Do you want to know about the best glass treatment touch screen display that enables you to perform the best function?

From an early time, we use different products daily for the convenience of work. Tablets, smartphones, and other products with touch screens have changed how we connect with devices. They have become so common that everyone expects many screens to have touch screen interfaces. A few products might have helped your desk as AR, AG, AF, and AS, whenever you work with your touch screen display manufacturer to design touch-enabled products. In this article, you will learn the best glass treatments, what they mean, and how they will work into your designs and the consumer experience? Let’s explore glass treatments, different kinds, their cost, advantages, and disadvantages.

1. Anti-Reflective (AR) Glass Treatment

Anti-reflective glass treatment involves applying a coating or film of a specific thickness to the surface of cover lens.

Anti-reflective glass treatments, also known as AR coatings, are applied to glasses via a series of attached layers to the front and back of the lenses. The layers help block specific wavelengths of light to minimize reflection on the surface. 

  • Process 

 When a specific wavelength of light passes through the AR material, some of it is reflected by the customer at the surface of the AR film, and some of its wavelengths are reflected at the surface of the cover lens. 

The consistency of the AR film causes the reflected wavelengths to be reflected precisely out of phase with each other so that they cancel the effect of each other. 

  • Cost

This coating or glass treatment generally costs about varied from size and thickness of glasses, more important is if there any special requirements like holes, silk-printings, unusual shapes. 

AR coating glasses look nicer in photos and in bright lights, making the glass less reflective.

2. Advantages of Anti-reflective Coating Glasses

AR coatings offer several benefits.

  • Better looking

One of the main benefits of this glass is that you will look better and increase the visibility of your eyes because you would not see the reflections in your prescription glasses. You will enhance eye contact with others and won’t be hindered by irritating reflections. This makes them ideal for people who do a lot of public speaking.

  • Durability

Another benefit is that it provides more durability as it lasts longer than regular lenses. Assume they are highly resistant to scratches and do an excellent job resisting water and dirt.

  • Reducing eye fatigue 

Also, AR coatings treatments help in decreasing eye fatigue at any work. This is suitable especially for people who spend long hours working on computers or other devices, which can cause significant eye stress. Besides using them for computer work, they are helpful while watching television to reduce eye fatigue. 

  • Improve Night vision

The anti-reflecting coating is also helpful in improving night vision.

Advantages-Of-Anti-reflective-Coating-Glasses

3. Disadvantages Of  Anti-Reflective (AR) Glass Treatment

On the other hand, anti-reflective coating glasses do have disadvantages.

  • Dirty look

They look dirty due to the transparency of the lenses. Then any regular pair of glasses and anti-reflective coatings are not any dirtier. As a result, you may have to clean your lenses more repeatedly, especially for some lower-cost AR coatings.

  • Not for Reading 

This lens generally isn’t suggested for reading glasses that rest on the low bridge of the nose. If you spend a considerable amount of time using a tablet, just read inadequate light conditions.

4. Anti-Glare (AG) Glass Treatment

Anti-glare glass treatment concerns creating a rough surface on the cover lens through an etching process.

Anti-glare glass can be tempered, laminated, or chemically strengthened. Unlike anti-reflective coated or untreated surfaces, anti-glare etched glass does not become highly reflective.

Light is scattered at different angles or reflected on the rough surface, which reduces the clarity of the reflected image. 

  • Process

A chemical-based surface process is applied instantly to the surface of the glass under the likes of sunlight to form micro severities and give the glass an anti-glare effect.

  • Cost

Anti-glare coatings are not expensive. It is similar to AF treatment, also varied from size and thickness of glasses, more important is if there any special requirements like holes, silk-printings, unusual shapes. 

5. Advantages Of Anti-Glare (AG) Glass Treatment

The advantages of the anti-glare are described below:

  • Better Appearance

Cameras flashes and bright lights can reflect off your lenses when you are not using anti-glare coating on your glasses. This can cause hinder your appearance when speaking to people or in public and make it tough to find the right angle for video calls. So the Anti-reflective coating eliminates the harsh reflections and permits others to see your eyes and face.

  • Reduced Digital Eye Strain

If you feel eye strain while using a computer or other devices, use anti-glare. The anti-glare coating helps reduce digital eye strain by lowering exposure to excessive glow from excessive lighting and digital devices.

  • Safe Driving at Night

The bright headlights from cars while driving in the opposite direction can be dangerous at night. These sudden glares can lead you to focus on the view ahead presently. AR coating on your eyewear effectively reduces reflections from headlights at night and enables you to enjoy a better road view.

  • Performance Indicator

Double-sided anti-glare glass has an anti-glare effect on both glass surfaces. The key is that single-sided and overall anti-glare meet specific performance hands, and it is an upgraded product of single-sided anti-glare glass. The glare glass’s superior anti-glare performance truly eliminates the phenomenon of screen reflection.

Advantages-Of-Anti-Glare-(AG)-Glass-Treatment

6. Disadvantages of Anti-Glare (AG) Glass Treatment

  • Damaging Over Time

 The thin layer of anti-reflective coating can get scratched down over time, making it harder to see clearly, affecting your vision over time.

  • Headache or Eye Strain

They would not prevent all glare and light from reaching your eyes, so it may cause you to have headaches or eye strain.

7. Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

Anti-fingerprint glass treatment is also a concern as an anti-smudge glass treatment reduces the ability of the cover lens to retain oils from your finger. In other words, anti-reflective glass treatment involves applying a film of a specific thickness to the surface of a cover lens.

  • Process

A liquid chemistry process generally uses AF/AS treatment, or vacuum deposition, that creates an oleophobic top coating. This layer is a chemical modification of the glass surface and is very durable compared to aftermarket AF/AS spray-on films.

The film minimizes the reflections on the surface by cutting out a specific wavelength of light as it is reflected to the user. The thickness of the AR film causes the reflected wavelengths to be reflected precisely out of phase to cancel each other out. Thus the user will not see reflection to own. Instead, they will see a more vivid display.

8. Advantages Of Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

The advantages of AF or AS are described below:

  • Easy to Use

The most important benefit of the AF/AS coating is the “feel” of the treated surface because the smooth surface and the finger will float more quickly than a non-treated surface. A non-treated cover lens surface causes the user’s finger to skip, feel, or draw a singular line on the screen.

  • Improve Oleophobicity

They help Increase oleophobicity and significantly improve the comfort of cleaning fingerprint contaminated surfaces. Unmistakable fingerprints with a dry cloth wipe.

  • Durability

It offers durability for long time use.

Anti-smudge Lenses Benefit you in Several Ways:

  • Clear Vision

It offers clearer vision without smudges or dirt covering the surface of the lenses from damage. 

  • Reduce Eye Strain

When you are not straining to see through fingerprints, there is a reduction in eye strain, and you feel happy.

Advantages-Of-Anti-Finger-Print-AF)-or-Anti-Smudge-(AS)-Glass -reatment

9. Disadvantages Of Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

  • Expensive
  • They can wear off and are a more expensive option in the long run.

10. Conclusion

We have explained the glass treatment touch screen’s different types, costs, processes, advantages, and disadvantages of glass treatment. We hope you understand or like the details about glass treatment.

  8. Final Words

Are you confused about how to choose a standard vs. custom LCD module for your use?

No need to worry now. Today in this article, I’ll explain everything about how you can choose the best LCD module according to your need. When considering a display module for your project, you will have to answer: “Should I design a standard module or customized one for my use?”  This article has described some tips, common misconceptions, and detailed answers to common questions to help you choose the best one.

1. Common Misconceptions About LCD

Here are some common misconceptions about LCD you kneed to know before your final decision.

  •  Custom LCD Modules Are Costly.

The common misconception is that custom display modules cost more than standard modules.

While the above holds for NRE cost, custom LCD module unit pricing is often equivalent to or lower than a similar product.

Here’s why: Standard display modules are often designed to maximize their implementation potential.

This can lead to:

  1. variable interface protocols allowed by high pin counts,
  2. high-output backlighting to maximize application potential,
  3. Generally conservative mechanical design practices.
  • Custom NRE Costs Are Too Restrictive.

For most Passive Matrix LCD modules, we can deliver a custom LCD with active area size and resolution or a custom backlight, mechanical housing, and electrical interface for a total NRE cost of less than USD 10k. Likewise, Createxplay can customize an Active Matrix LCD module’s backlight, housing, and mechanical interface for an NRE cost of less than USD 10k. 

In these cases, the design flexibility justifies the modest NRE required that customization often allows.

However, customizing the Active Matrix LCD itself (size/resolution) can cost restrictive for most applications since the minimum NRE required for panel mask sets is around USD 100k. Unless the scope of the business dictates a customer-owned TFT panel or the project volumes depending on the size, are over 500k pieces per year. In many applications, combining a standard active matrix TFT cell with a custom-designed module and electrical interface offers the most favorable overall cost solution.

  • Designing Custom Modules Extend Lead Time.

The lead time is another consideration for a custom design that can be shorter than you would think. Short lead time is made off-the-shelf LCD modules attractive for designers.

LCD manufacturers like Createxplay can typically design custom housing for passive or active matrix LCDs – with integrated capacitive touch sensor and interface – within one to two weeks of the initial RFQ and then provide sample custom LCD modules 4-5wks after that.

Createxplay also offers customers the option to use off-the-shelf modules as prototypes within their design before the custom display is ready to evaluate other design aspects and perform qualification work (e.g., testing software).

For many implementers, the design freedom and iterative optimization that customization offers are well worth the additional time required to sample custom LCD modules.

Advantages-of-Liquid-Crystal-Display

3. Customized LCD

Nowadays, different LCDs are used in various applications, from calculators, watches, games to medical and industrial applications. The display content easily modified to satisfy the exact requirements of an application is one of the main advantages of LCDs over all other display technologies. The customized LCD panels can show particular user interface information that enhances the product performance and value.

Customized LCDs display alphanumeric digits, numeric, ON, or OFF indicators, graphic icons, messages, pie charts, bar graphs, symbols, etc. The content of the LCDs panel is limited only by the product designer’s imagination. Many factors should be considered in the design of a customized LCD panel. 

4. Important Information To Design Custom LCD Panel

The following information is necessary to design a quotation for a customized LCD panel:

  • LCD panel, 
  • Display modes, 
  • Polarisers, 
  • Viewing mode, 
  • Backlight requirement, 
  • Operating environment, 
  • Drive method, 
  • Connection method, 
  • A keypad is required if applicable.

  • Portable test equipment
  • Diagnostic device
  • Electric, water, gas meters
  • Telecom products
  • Measuring device
  • Marine equipment
  • Medical equipment
  • Automotive display

Do you want to know the important matters needing attention for the outdoor LCD display with causes and solutions?

This article will discuss them in detail with solutions for you.

As a new carrier of self-service to our life, outdoor LCD has brought great convenience. Outdoor LCD self-service can be seen everywhere in our life.

1. When It Comes To Outdoor LCD Display Hardware?

Outdoor LCDs become lighter, brighter, more efficient in power consumption, and have higher resolution every two to three years. To ensure investment efficiency, “everything should be based on actual needs and avoid blindly following the trend” has become the basic principle of end-users purchasing. 

There are some important matters needing attention for outdoor LCD display:

2. Structure Design Of Outdoor LCD

Outdoor LCDs are generally large and very heavy. The home page needs to pay attention to the structure’s design for installing the outdoor touch screen display. Firstly, the installation structure should consider wind resistance, bearing capacity, earthquake resistance, and other major factors.

Secondly, the display screen should coordinate the structure, shape, and exterior decoration design with the architecture. Moreover, it considers local environmental factors, such as air humidity, air salinity content, etc.

Structure-Design-Of-Outdoor-LCD

3. Light Pollution Of Outdoor LCD

The popularity of LCDs has led to “light pollution. ” 

Do LCDs count as “light pollution”? 

The definition of light pollution is usually divided into three international categories: white light pollution, color light pollution, and artificial daylight pollution. Currently, only China has relevant regulations for the glass curtain wall in white light pollution but no relevant laws for artificial daylight and color light pollution. The display screen design has been regarded as the prevention and control of light pollution.

Solutions:

3.1 Proper Planning Of The Outdoor Area And Installation Location Of The Display Screen

You should choose an outdoor area and installation location of the display screen according to the viewing distance and angle of the surrounding environment, the display content requirements, and location. 

3.2 Selection Of Display Content And Design 

When choosing the display content, it must agree with the general requirements. The GUI design of the outdoor display screen should be dark-colored to avoid causing discomfort to users’ eyes. You need to make the color look soft color and transition natural.

3.3 The System Can Automatically Adjust The Brightness.

Different times and places of the brightness of the environment change greatly if the screen brightness is greater than the environment too much. It will cause people’s eyes not to adapt, especially since the brightness of the difference between the day and night is large. Our automatic brightness adjustment system drives light pollution; an automatic conversion is suitable for the air environment brightness and avoids light pollution.

Many outdoor LCD manufacturers have done a lot of work in the field of the outdoor display to enrich our visual space light up a better life to make a great contribution relative to the original TNT and other traditional display products; in recent years.

4. Top 5 Precautions For Installation Of Outdoor Display Screens

There are some precautions for the installation of the outdoor display screens, which are given below:

4.1 Lightning Protection Measures For The Installation Of Buildings And Screens

The display screen body and the protective layer of the outer packaging must be grounded to avoid strong electromagnetic lightning attacks. The grounding line’s resistance should be less than 3 ohms to timely discharge lightning from the ground wire.

Top-5-Precautions-For-installation-Of-Outdoor-Display-Screens

4.2 Measures the Screen Body Waterproof, Dust And Moisture-Proof 

The connection between the box body, the joint of the screen body, and the force installation object to avoid leakage and dampness should seamlessly connect. Inside the screen body, the situation can be dealt with in time to have good drainage and ventilation measures if there is water inside.

Top-5-Precautions-For-installation-Of-Outdoor-Display-Screens

4.3 Choice Of Circuit Chips

In cold areas, the temperature in winter generally reaches minus ten degrees. When choosing the circuit chip, selecting the working temperature in the negative 40 degrees Celsius refers to 80 degrees Celsius of the industrial chip to avoid difficulty using LCD due to the low temperature.

4.4 Ventilation Measures Inside The Screen Body 

A certain amount of heat will generate when the screen is powered on. If the heat cannot be discharged, it will get to a certain extent, which will cause the internal ambient temperature to be too high and affect the work of the integrated circuit. If heat cannot be discharged, it will burn down seriously, so the display can not operate. Therefore, the internal environment temperature is kept between negative 10 degrees and 40 degrees. It is necessary to do good ventilation and heat dissipation measures inside the screen body.

4.5 Highlight The Choice Of Wick

The high brightness LED backlight display can face direct sunlight and enhance the contrast with the surrounding environment. The audience of the picture is broader; in the distance, an overall perspective of the place still has a good performance.

Top-5-Precautions-For-installation-Of-Outdoor-Display-Screens

5. Some Misunderstandings About Outdoor LCD Display Hardware Equipment 

5.1 The Longer The Life, The Better

According to human inertia thinking, the longer the product’s service life, the better. This is no exception in purchasing outdoor LCDs, and this idea is not advisable. We should keep in mind that the longer the service life of outdoor displays, the higher the technical requirements. The related manufacturing costs will naturally increase, and the industry users will have to invest more money. Industry users will choose to use the product as long as possible to ensure the return on investment. Balance the use cost and application experience, users in the purchase of outdoor liquid crystal display should not blind foot pursuit of long life, according to the application needs.

5.2 The Brighter The Screen, The Better

Nowadays, highlighting has become an important parameter in outdoor liquid crystal displays, highlighting the leading technology. It is indefinite amplification in the marketing publicity by some manufacturers, which directly causes many users to produce serious highlighting properties. The screen is not as bright as possible; the effect of screen brightness is a superimposed effect, including the contrast, viewpoint, viewing distance, the brightness of the surrounding environment, content, and so on. Therefore, simply the pursuit of high brightness cannot necessarily achieve the best application effect, even having a negative impact. For instance, the higher the screen brightness, the heat generated, the consumed power will increase, the maintenance costs, and highlighting the high price of the product itself, to greatly increase the capital investment, does not fit the established economic principles. At the same time, in indoor applications, too bright a screen may cause discomfort to the eyes, thus affecting the audience’s viewing experience.

5.3 The Metal Casing Is Safer And More Practical

At present, many outdoor commercial displays will be equipped with metal cases. Under manufacturers’ guidance, many industry users have been convinced that metal cases are more secure. Unless the outdoor LCD is installed in a public space where people can tamper, the metal case becomes a completely unnecessary expense. For example, the elevator billboard in the office and the information displayed at the cash register in the back are almost inaccessible to outsiders, so they are very suitable for applying plastic cases.

5.4 The Smaller The Player, The Better

Out of the demand for beautiful design, many users prefer to choose small products, which is understandable but also moderate. The installation of compact player products is flexible, and it puts forward higher requirements for the cooling design, and once the cooling problem occurs, the results are unimaginable.

6. Final Words

The increase of technical threshold leads to the high cost and increases the potential risk of system application. After all, the liquid crystal display needs 7×24 hours of continuous operation. You can choose outdoor displays wisely. If you still have any questions, contact us.

Touchscreens grow in popularity as a part of user interface systems and become a critical design decision. Each type of touchscreen, resistive or projected capacitive, offers many advantages. 

Do you want to know how to select the one that provides the optimal user experience from the wide variety of touchscreen options?

1. What Is Touchscreen Technology?

Traditional input devices for computer systems contain keyboards and mice. Touchscreen technology has become widely used to interact with computer systems and mobile devices.

A touchscreen is an electronic visual display that a user controls by touching the screen with fingers. A touchscreen allows more direct interaction with what is displayed than a mouse device. Touchscreens have become very common on smartphones, tablet computers, and other mobile devices. Additionally, standard laptops and desktop computers use touchscreen displays to use both touches and more traditional ways of input.

The first major successful technology was the resistive touchscreen, which uses a panel including two thin, electrically charged layers separated by a narrow space. These two layers touch by pressing the panel, and the location of the connection is recorded as the input. Resistive touchscreens are somewhat cheap and resistant to liquids, but they have relatively poor contrast, and you need to press them down with some pressure. Resistive touchscreens did not become widely used for computer systems but developed as part of other electronic systems. For instance, control panels in factories and the display screens used in restaurants to enter orders are resistive touchscreens.

The second major technology used in touchscreens is the capacitive touchscreen, which uses a layer of insulating material, such as glass, coated with a transparent conductor and touching the screen with your finger changes the screen’s electrostatic field. Several approaches can be used to record the location of the touch. Using a fine grid of capacitors is one of the most common ways to record the electrostatic field’s change.

2. Multi-Touch Gestures

Touchscreen technology works similar to a computer mouse at a basic level. Instead of moving your pointer with a mouse, press the location with your finger. Multi-touch technology makes it possible to interact with the computer display in many ways. With touchscreen technology, tasks like scrolling up and down a web page, selecting text and drag-and-drop have become quite different. This figure shows several single and multi-touch gestures.

Things To Consider When Choosing A Touchscreen Technology

There are some important things you need to know while choosing a touchscreen, which are given below.

3. What Is The Intended Use Of The Device?

The first step is to precisely define what the device will be used for and which touchscreens are feasible. For instance,

Is the screen intended for an inexpensive toy where durability is not a huge concern?

Will your display be for a military application, subject to harsh conditions? 

Both situations require different durability, functionality, pricing, and input registration screen technologies. The next step is to figure out which functionalities are necessary once you have narrowed down the planned use for the display.

4. Which Touch Features Are Required?

You should know about users’ preferences; for example, will users only need to select single inputs with one finger on your device? 

If Yes, a standard 4-wire resistive touchscreen is perhaps a perfect option for them. A 4-wire resistive touchscreen’s simple construction handles this without adding much cost. However, if users need to zoom, scroll, or activate features with multiple touchpoints, that will narrow the selection to screens with multi-touch functionality, such as a projected capacitive or a resistive multi-touch screen.

5. How Will The Touchscreen Be Activated?

Given how touchscreens register inputs, activating the screen is an important consideration. 

Will the user wear gloves or another object to touch the screen? If so, specific types of touchscreens are necessary to register those inputs. While the sensitivity of a projected capacitive touchscreen can be adjusted to note certain styluses and gloves, the object used must be able to disrupt the capacitive field. A resistive touchscreen is optimal for applications where other input devices can register inputs from nearly any object.

6. What Is The Environment To Use Touchscreen?

Where the touchscreen will activate is another essential factor to consider.

Is it subject to drastic cleaning agents in a medical setting?

Will it be used in an industrial environment to repeat impacts? 

 PCAP technology is ideal if durability is a vital concern, given that damage to the cover glass does not change its ability to register inputs correctly. Resistive screens meet performance requirements for softer environments without adding additional cost.

7. What Is The Price Point?

Resistive touchscreens still tend to be cheaper, as PCAP touchscreens technology becomes more popular and its cost decreases. If you are looking for a touchscreen for a game, toy, or other cheap application, a simple 4-wire resistive touchscreen may add unnecessary cost to the device. However, a projected capacitive screen will be worth the additional cost in the case of a computer, smartphone, or other costly application that requires a high-end look.

8. How Many Actuations Does The Touchscreen Require To Handle?

Different touchscreen constructions are ranked for different numbers of actuations. A 4-wire or 8-wire resistive touchscreen will be optimal for a device that needs to remain accurate only for a few thousand actuations. In contrast, if the device will require significantly more usage, a 5-wire touchscreen is a better choice. However, a projected capacitive screen would be ideal if a display handles millions of actuations, as it can maintain its accuracy over infinite inputs.
