  • Cold Shaded Light Tubes 
  • Light guide Panels 
  • Optical Films

 

Liquid-crystal-display

2. TFT LCD Technology 

LCD is a liquid-crystal display. Most of the current market uses TFT-LCD or thin-film transistor liquid crystal display technology. TFT-LCD consists of a layer of liquid crystal sandwiched between two glass substrates. The lower glass layer is inlaid with electro-crystals and the upper glass substrate is a color filter. The electric field passes through the crystals created by the electric current and making the original rotational arrangement of the liquid crystal molecules twist. Different colors produce by changing the rotational amplitude of the light passing through and shining on the color filter in different proportions.

  • LCD panels are made using TFT-LCD technology. 

It Includes:

  • Polarizers
  • Glass Substances 
  • Color filters
  • Colored molecular layers
  • Glass substrates
  • Polarizers
  • Backlight Module 

It is now quite grown and is used for TV screens and public computers. And It is a low-cost technology that has become the foundation for consumer products.

After understanding LCD and TFT LCD, let’s move on to LED and OLED technologies. 

TFT-LCD-technology

3. LED Technology 

The LED is called a light-emitting diode, which uses electrical energy to convert into light energy by applying a voltage to the positive and negative terminals in the semiconductor. The electrons combine with the electric hole when the current passes through, and the remaining energy is released in the form of visible light. The direct display LED is commonly used for outdoor traffic lights or TV walls. LED chips are the mainstream TV, screen backlighting, and lighting products.

  • LED technology uses electrical energy to convert into light energy, and it includes:
  •  Optical
  • P-Type Semiconductor
  • N-Type Semiconductor 

LED-technology

4. OLED Technology 

Generally, the concept of conducting LEDs is quite similar to that of OLEDs.  But the materials used in LEDs are totally different because OLEDs are called organic Light-Emitting Diodes and shortly OLEDs. The basic structure of OLED consists of an organic material light-emitting layer made on Indium Tin Oxide glass. It is covered with a low power function metal electrode on top of the light-emitting layer. An external voltage drives the light-emitting diode. The cathode electrons combine in the light-emitting layer to emit light and generate energy, producing R, B, and G primary colors depending on the characteristics of the material from the primary colors.

  • OLED technology includes:
  • Polarizers 
  • Substrates
  • Electrodes
  • Electron layers
  • Organic light Emitted layer
  • Electron hole layer
  • Electrodes
  • Substrates 

The most noteworthy difference between OLED and LCD is that LCDs require LED backplanes and filters and OLEDs are self-luminous.

Although OLED presents a vivid picture, has low power consumption, and can be bent, the organic material will oxidize, so the life span is relatively short. There will be problems with color burn-in, coupled with high technical content and the high cost. Currently, it is mainly used for small screens only, such as mobile phone screens, etc.

Now, we will look at advanced display technologies like Mini LED, Micro LED, and Micro OLED. After understanding the fundamental differences between LCD, LED, and OLED.

OLED-technology

5. Mini LED Technology 

The most automatic difference between Mini LED and Micro LED is the size of the LED crystals. But there is a slight difference from a conceptual point of view; Mini LED is formally known as a sub-millimeter light-emitting diode, while Micro LED refers to the micro light-emitting diode.

  • Micro LED technology no longer requires a filter and liquid crystal layer, and it includes:
  •  Anti-glare and Protective films 
  • RGB micro LEDs
  • Electrodes
  • Substrates

Mini LED is considered as the transition period of Micro LED. It is an improved version based on the conventional LED backlight and used as the backlight of LCD panels. Micro LED is regarded by the industry as the new generation of display technology and matrixing the LED backlight. It is dedicated to driving inorganic self-lighting or self-luminous alone and allowing longer product life and even perform better than OLED.

Mini LED technology is currently mainly used in multi-zone backlight displays and large RGB small pitch displays. The multi-zone backlight control function can be achieved by zonal dimmings, such as the screen’s high resolution and enhancing the high contrast ratio, or performing the HDR effect. The effect is similar to OLED displays; another technology uses Mini LED chips to create a display with a pixel pitch lower than Pitch 1. Mini LED chips are another technology used to create large screens with a pixel pitch of approximately less than 1.0 mm, which improves the resolution of LED display screens. It creates a new mainstream specification for display screens.

Mini-LED-technology

6. Micro-LED Technology 

Micro LEDs will bring a new technological breakthrough. Their use is not only specified to backlighting, as the grains of Micro LEDs are of an indistinguishable grade to the naked eye.  Also, it can directly combine the R, G, and B primary colors into a single pixel, turning it into the concept of one pixel. 

  • The technology is different from the light-emitting structure of previous LCD screens.
  • Huge Transfers
  • Wafer Dicing 
  • Red, Green, and Blue LED wafers

Moreover, to create a whole new scenario for the LCD industry, the future of Micro LED has a wide range of applications, including automotive screens, VR/AR devices, and high-resolution wearable products. However, Micro LED technology has many significant difficulties, like Mass Transfer yield, packaging testing problems to the next inspection and maintenance. These are all critical challenges and affect whether Micro LED can be mass-produced or not.

Micro-OLED-technology

7. Micro OLED Technology 

As Apple has approached TSMC to collaborate on the development of Micro OLED panels, Micro OLED has been the talk of the town this year. It is not like traditional LCD or OLED for TVs and high-end mobile phones where the screen is built on a glass substrate.

It is directly mounted on a wafer, which is the essential feature of Micro OLED. Micro OLEDs use a single silicon wafer as the backplane especially suitable for AR, VR, or other display wearable devices.

It has the advantages of making the display thinner, shorter, lighter, self-luminous, high luminous efficiency, and consuming less power.

Micro-LED-technology

7. Final Words

All the above LCD, LED, OLED, Micro LED, Mini LED, Micro OLED has their own features and characteristics, and all are useful for humanity’s services. So You can choose one of them according to your need and desire based on their uses.

 When you buy an LCD display, you may face the five most common issues, and you would like to contact us for their solution.

1. What Are The Five Key Lcd Display Challenges You Can Face?

There are only five problems with LCDs you can experience with them. Five simple words that can equate to significant LCD display challenges for you. 

  • Obsolescence
  • Delivery
  • Quality
  • Performance
  • Cost

But why would you ever call us? 

Here’s how you can successfully address and resolve the above 5 LCD challenges.

How Will We Help You?

We Simplify the conversation by identifying your exact pain points so we can quickly identify your needs and figure out if we can solve them.

In order of occurrence, these are the only five reasons to contact us:

What-are-the-five-key-LCD-display-challenges-you-can-face?

2. Obsolescence

The most common of the five issues are obsolete displays. The display suppliers have discontinued the display without providing a suitable replacement but our customers are still producing their end product.

Why Does This Issue Happen?

For the occurrence of the above issue there are two reasons which are following:

Two Reasons:

1) The overall volumes for this part reached a low threshold, and the supplier does not want to support it.

2) The components within the LCD have gone obsolete or over-dated.

What Can We Do?

Because we create custom displays, we have the ability to be able to produce un-obsolete displays.

1) If volumes are too low to support a custom display, we would recommend changing the end product to accommodate an available standard display. 

2) Solving an obsolescent component is more complicated. We have complete control of all parts within a display, except for the LCD driver IC and the color TFT LCD glass (monochrome glass is not an issue).  

Our process is to find the closest standard TFT panel and closest standard driver (if outdated). 

We do an obsolesce analysis on these replacement components to ensure we have the most extended lifetime with this new arrangement before starting the design work. We use our crossmatch program to redesign the display near these non-obsolete components.

Our focus is on eliminating any differences between the obsolete display and our new replacement. Not only is this process for new customers, but it’s the standard operating procedure for our current clients. We do not have obsolete configurations due to low volumes. We automatically go through the redesign process at no cost to our clients if any component goes obsolete within our display. Therefore, we come to our clients with the obsolescence notification and the solution to keep them up and running. 

Obsolescence

3. Delivery

Why Does This Issue Happen?

If we talk about delivery, longer than expected lead times and inconsistent deliveries lead to missed customer commitments and cause stress on manufacturing.

One of the main reasons customers are forced to switch suppliers is delivery. Learn what goes into actually getting a product to you and how CreateXdisplay might be different.

Missed deliveries are a killer with even if one component is missing, an assembly line goes down, missing revenue goals, affecting operations, and failing customers. Parts frequently have lengthy and variable lead times, leading to production and subsequent delivery problems if they’re not managed effectively.

What Is The Solution?

Proactively address this challenge within your company and the LCD display provider. Assure suppliers’ lead times are accurate in your MRP, Internally. Further, maintain a 2-4-week buffer stock or more depending on component scarcity and lead times.

The LCD display supplier can carry a buffer stock for your application. Effective display providers like CreateXdisplay can adjust production schedules, pressurize the upstream supply chain, partial ship quantities, and accelerate shipments. A good thing is applying these solutions reduces most delivery problems and handles unplanned customer demand. Because we have full production lines. From glass cleaning to final LCD.

Delivery

4. Quality

Quality should not be mistaken with performance as they both are different. This is where the LCD is not meeting the specification standards or simply a clients’ expectations.

Why Does This Problem Occur?

A manufacturing LCD failure is an expensive issue and even it could be more costly later.

Generally, quality issues arise in a few ways. 

First, the LCD’s failure to fulfill the performance specification as intended. This involves customers’ needs and defining what’s required to satisfy the product’s intent.

Second, there are the mechanical and visual aspects of LCD display manufacturing. This includes maximum defect limitations and meeting dimensional tolerances.

What Is The Solution?

A supplier that manufactures to your specific needs will minimize quality issues due to their expertise by modifying the LCD display for your particular product, ability to bring flexibility, and then actively supporting ongoing product improvements.

Quality

5. Performance

What Are the Performance Issues?

This is where the component does not work as you want or expect. The display could meet the specification very well. A little improvement to contrast, sunlight readability, response time, brightness, color gamut could make the end product work better and ultimately help our clients sell more of their product. 

Defining performance begins with the application and some basic questions listed below. 

  • Who is the end-user, and how will they interact with the LCD display? 
  • In what environment will it be used? 
  • How is it being sold to customers? 
  • What type of data does the LCD need to convey? 
  • Is it must be readable by the visually impaired?

What is the Solution?

We can define the ideal display type, pixel density, size, contrast, brightness, temperature range, color gamut response time, etc when performance is fully understood. 

Over-specifying any of these factors will add unnecessary cost, while under-specifying any factor will detract from the end product’s usability. Ensure performance is optimized for your application to be successful. It is critical to find an LCD display provider who will willing to adjust explain them to you in terms of the end-user experience and customize these particular variables.

Performance

6. Cost

What Is The Cost Issue?

Surprisingly cost issue is the least common. The pain of changing LCD suppliers is high, such that all the problems mentioned above end up costing more than a regular cost delta between competitive suppliers.

An LCD’s cost is an obvious challenge as it’s usually the most expensive component. The challenge is that cost is also difficult to quantify and properly understand. Determining the right price to pay depends on three main factors. 

  • What does the display need to do? 
  • What does the display not need to do?
  • What quantity is required? 

The ideal option in most cases is a custom or semi-custom display designed for its application. This is often the most cost-effective solution, despite what many think.

What Is The Solution?

You expect a lower price point with greater volume, which goes hand in hand with provider selection. 

Oversimplifying this for you, imagine three categories; 

  • low-volume – standard product distributors; 
  • mid-volume – built-to-order custom semi-custom suppliers; 
  • high-volume – consumer market suppliers.

You will never get to the optimal volume pricing with a low-volume stocking distributor for a high-volume consumer product. Start work with the right provider who serves that particular category after identifying where you fit.

System-level manufacturability is another cost challenge where display integration improvements can reduce product complexity, improve manufacturing time, and reduce system-level manufacturing defects. For the most seamless LCD integration, additional components such as buttons, LEDs, PCB boards, and connectors are more efficiently integrated on display than a separately assembled component. Clearly, in this case, the LCD cost will go up, but when done right, the system-level cost is reduced to result in a net gain.

Lastly, you need to know system-level costs. You are trading market share and profitability for display savings, and the net result may be decreased profit if you are giving up customer valued performance or functions. The opposite also holds; adding performance that is not necessary (these are attributes that the customer does not value) adds additional product costs.

Cost

7. Conclusion

Choosing the right supplier based on your volume and quality needs is essential. Then implement the optimal LCD solution with the optimal features and performance.  

We strongly encourage our clients to reach out to us if they are developing a new product that requires a display or has any one or more of these problems.

Are you looking forward to getting a high-quality, advanced and affordable LCD display but do not know what makes it high quality?

Today we will discuss some essential things that you need to know like quality vs. performance factors, developing a well-defined quality assurance process, and quality-related aspects that would be important when buying an LCD display.

A high-quality and affordable LCD display is necessary for fully managing end-user cases. Liquid crystal displays with defects and cosmetic deficiencies can only spoil your reputation with your buyers. However, people are often confused with the terms “performance”  and “quality,” which can lead to incorrect questions in their purchase decisions.

This article will explore the difference between these two terms and answer the question, What makes a high-quality and affordable LCD display?

1. The Difference in b/w Quality And Performance

In this part, we will talk about both performance and quality. 

Performance is an area of quality-focused display elements that the customer would want to see and interact with. 

Quality is about the manufacturer’s proficiency to meet agreed-to-all specifications and requirements. It’s about defining what the product is supposed to do, then producing the product to do that perfectly and consistently.

 

The-difference-in-B/W-quality-and-performance

Additionally, the quality typically contains three main areas:

1.1 Cosmetic

Cosmetic includes some items such as spots, missing pixels, scratches, LCD glass colors, pixel, backlight color, and other prominent or physical defects on the surface. There could also be wrongly assembled components or poorly fused joints on a craft level. 

LCD-cosmetic

1.2 Electrical 

Electrical Is the product operating at the correct voltage? Is the LCD over-driven or under-driven? Is it drawing the right amount of power?

Voltage-of-LCD

1.3 Performance

Operating temperature, response time, reliability, LED lifetime, contrast, brightness, color gamut, and viewing angle are Example aspects of performance.

Customers may have their unique requirements involving drop-test criteria, specific mechanical limitations, and electrostatic discharge (ESD) beyond these areas.

Performance-of-LCD

2. Developing a Well-Defined Quality Assurance Procedure

Designing a high-quality LCD display means that all quality requirements are fulfilled. To get this quality, the manufacturer needs to have a well-defined quality assurance (QA to accomplish this) process. It’s how to consistently meet all the quality requirements.

Developing-a-well-defined-quality-assurance-procedure

Here are the specific QA process areas you should know:

2.1 Qualification 

Qualification is the initial testing of the new product for every performance factor, including contrast, vibration, and temperature cycle.

Qualification-of-LCD

2.2 Sampling

It is very important to test a predetermined selection of displays to ensure consistency. This may be completely random, including every lot, some other sampling method depending on the sampling plan. In addition, the factors tested for the samples of the product could include every requirement or only a select few.

Sampling-of-LCD

 2.3 Final Assembly Test 

What is being tested after the display is fully assembled? 

  • Functionality,
  • cosmetic defects, 
  • voltage, 
  • all of the above areas? 

All the above factors are often determined by the product, as some require more strict testing than others.

2.4 Process 

What is the documentation, training, tools to ensure that each step of the manufacturing process is as simple and as consistent as possible? And what other processes are put in place to ensure that each display produced consistently meets the original design specification?

There could also be testing throughout the manufacturing process. For example, at PDI, we test 300%—including tests along the manufacturing path to catch any defects early on and avoid adding value to wrong parts, as well as burn-in tests that entail running displays for a certain amount of time at higher temperatures to catch any latent defects.

3. What Are Quality-Related Aspects to Consider When Buying an LCD Display?

From a customer perspective, there are several questions you need to ask your manufacturer before purchasing LCD displays from them:

1) What is the expected defect rate for the type of your desired display?

2) What is the test process of manufacturers? 

For example, 

  • What is tested? 
  • How are they tested? 
  • And how often are they tested?

3) What is the return merchandise authorization (RMA) process of the manufacturers? 

For example,

  • What happens when there is a defect?
  • Who pays for the product and shipping? 
  • What are the responsibilities on both sides? 
  • Will, there be a corrective action for every defect?
  • Or is there a defect-rate threshold that needs to be reached first?

1. Understand Your Customer’s Expectations

First, you need to understand your customer’s expectations from your product or services. We have seen many technological improvements in the display module space, such as monochrome custom LCD, TN, and FSTN LCDs and various functionality enhancements that can be done perfectly. It may be difficult for you to understand the benefits of all displays in this fast-paced world with many technological improvements. Unfortunately, everyone wants their product without knowing its pros and cons and a proper understanding of the technology.

Do you take the time to understand what you need or what you want to see in your product?

Many companies primarily establish only a particular display module without understanding whether other options may better suit their needs; they don’t thoroughly evaluate the customer’s expectations and result in under-performing or over-engineered products.

These factors significantly affect the cost, design cycles, and user experience. For example, the optical bonding of cover lenses sounds like a must-have is a mistake, as it may not always be required.

 Answer To Some Important Questions 

To get a clear understanding, you need to answer the following questions in detail. All companies need to ask these questions before engaging in a display project, and These questions are as simple as:

2. What Are The Types Of Custom LCDs?

There are many types of Liquid crystal displays that you can choose from. Some are modern technology, and others are older types of displays.

What-are-the-types-of-custom-LCDs?

There are some categories, and types of the LCD are:

Monochrome can be divided into:

  • Graphic LCD
  • Segment LCD

Multi-Color

  • CSTN(Kind of STN)
  • TFT
  • Silk-Printing for monochrome LCD(TN, HTN, STN, FSTN, DSTN, VA)

3. What Type And Size Of Display Do You Need?

Custom LCD screens are available in various sizes ranging from tiny digital watches to enormous televisions. They are also used as glass or plastic panels, where LCDs use two glass panels.

You can measure the size in inches from corner to corner, and almost any size is available. The largest LCD we can make is 460*360mm because the whole glass panel size is 470*370mm.

There is a higher interest in a small custom LCD Display module. At present, the minimum size of the display can reach 10*10mm that we have designed and mass-produced.

4. Do You Need A Reflective Or Transmissive Or Transflective Display?

Polarizer displays have three types, including reflective, transmissive, and transflective and you need to choose from them, as they are different.

  • Transmissive LCD 

It is always combined with a backlight, although it can be used without a backlight we generally don’t recommend this. 

  • Reflective LCD 

It does not have a backlight because its bottom film does not transmit light and the contents on the screen can only be seen with the external light source.

  • Transflective LCD 

It is a combination of both transmissive and reflective technologies so it can be used without backlight or with backlight.

5. What Functionality Are You Expecting?

You should be clear about the functionality you are expecting from your display. A liquid crystal display is an electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. LCDs use a backlight to produce images in monochrome or color as they do not emit light directly.

6. What Type Of Interface Is Needed For Your Product?

We divided the interface of LCD into 3 kinds. Pin assignment, conductive tape, and FPC.

If the LCD is small and not enough space for the connection to the PCB, we will choose conductive tape for it.

If there is enough space for connection, we will choose pin assignment or FPC. It can be determined by the product’s frame.

If there are so many icons and symbols in the LCD, we will choose FPC for it, then it will be a COF frame. Because it needs an extra IC to drive.

If the IC is on the board, there will be so many ways for the connection. PIN assignment, conductive tape, or FPC all can be. (Yes, FPC also can be, because the FPC can be treated as a flexible way for the frame, and IC can be on the board, FPC as an extended part of the connection.)

7. What Level Of Backlight Brightness Do You Need?

Generally speaking, when the size is fixed, the higher the brightness required, the higher the thickness of the backlight will be because brighter lamp beads are used.

If the thickness is fixed, then another way to increase the brightness is to increase the size of the backlight so that more lamp beads can be added.

The third way is to change different led beads, there are many different led beads for backlights. Like Philip, Samsung, etc.

8. Does your display module need a touch panel?

A touch panel is a piece of equipment that lets users interact with an LCD module by touching the screen directly. Incorporating features into the monitor like sensors that detect touch actions makes it possible to issue instructions to a device by having it sense the position of a finger. A touch panel can be a resistive touch panel or a capacitive touch panel.

Normally, a monochrome LCD doesn’t need a touch panel. TFT LCD will need a touch panel.

9. What Is Your Operating Temperature Range?

Generally speaking. We divided temperature ranges into 4 tiers.

First, the working temperature is 0 to 50 degrees, storage temperature is -10 to 60 degrees.

Second, the working temperature is -10 to 60 degrees, storage temperature is -20 to 70 degrees.

Third, the working temperature is  -20 to 70 degrees, storage temperature is -30 to 80 degrees.

Forth, the working temperature is -30 to 80 degrees, storage temperature is -40 to 90 degrees.

And it’s clear that the price is from low to high. You need to choose from them for your custom display module.

10. Do You Need An Extra Layer Of Protection From A Glass Cover Lens?

You should be clear about the protection level of the required display. You need to know clearly whether your display needs an extra layer of protection from a glass cover lens or not. If yes then go for it. 

The above list is not a complete list of questions but food for thought – enough to move the design process on solid ground.

These fundamental questions help display module manufacturers quickly whittle the choices to a handful. This does not mean that further adjustments are not required, but it makes the process of choosing the correct display smoother and less cumbersome.
