A resistive touch screen monitor consists of a glass panel and a film screen separated by a short gap coated with a thin metallic coating.

1. What is a Resistive Touch Screen?

A resistive touch screen monitor consists of a glass panel and a film screen separated by a short gap coated with a thin metallic coating. These two metallic layers come together and generate an electrical flow when you contact the screen. This voltage difference is what detects the site of touch. After that, the voltages are translated into X, and Y coordinates are then sent to the controller.

2. Where Is It Used? 

Resistive touch screens are widely used in manufacturing, ATMs, kiosks, and medical equipment due to their longevity. Because most businesses require users to wear gloves while using touch screens, the resistive option is suitable because it does not need contact with exposed human skin or a capacitive stylus. Furthermore, resistive touch panels are less expensive and simpler to operate in harsh situations and industrial settings.

3. Types Of Resistive Touchscreens 

Electrodes that provide a constant voltage across the conductive region are used in resistive touch displays. When a portion of the two layers comes into contact, this produces a precise voltage readout. The kind of resistive layout impacts the monitor’s longevity and sensitivity. As a result, manufacturers provide a variety of resistive touch displays.

3.1 4-wire analog

Two electrodes are positioned perpendicularly in this configuration’s top and bottom layers. Electrodes on the bottom sheet are used in conjunction with electrodes on the top sheet to construct the positive and negative X-axis. Thanks to its electrical-coordinate configuration, the gadget can detect the coordinates whenever these two layers come into contact.

3.2 5-wire analog

The 5-wire analog arrangement has four electrodes at each corner of the bottom layer, connecting four wires. The circuit is more durable than previous designs due to a more straightforward design with fewer components.

3.3 8-wire analog

This is the most sensitive resistive touch screen that is currently available. The configuration of the 8-wire sensing circuit is identical to that of the 4-wire analog. There is one distinction, however: each bar electrode has two wires. This increases the circuit’s redundancy. However, the touch screen is very durable and aids in avoiding detecting the user’s finger or stylus incorrectly.

Advantages of Resistive Touch Screen

Good resistance 

Resistive touch screens’ surfaces are more prone to wear and scratching than capacitive ones since the two layers of material they utilize are synthetic (rather than natural, like glass).

● Lower price tag

The cost of resistive touch panels is lower than that of capacitive touch displays, which have a more complicated technical structure.

The versatility of touch

Resistive touch screens may respond to a variety of different sorts of touch. Because they have more sensors per inch than capacitive touch displays, they can record input from gloved or ungloved fingertips at a precise point of contact.

 ● Lower sensitivity 

A resistive touch screen responds to touchless sensitively than a capacitive one. While sensitivity to touch might be beneficial, it is not in circumstances where random stimuli such as liquid spills and splatters can induce individuals to respond accidentally. As a result, resistive touch displays are often employed in industrial settings, while capacitive touch screens are found in consumer goods such as tablets and smartphones.

Advantages-of-Resistive-Touch-Screen

Drawbacks Of Resistive Touch Screens

  • Sensitivity to light touch is reduced.
  • The display’s clarity suffers as a consequence of the thick top layer.

Are you considering acquiring a resistive touchscreen? Whether it’s for business or play (or both), you’ll need to choose the appropriate kind. While all resistive touchscreens have two electrically resistive layers, they are different.

Things To Consider When Choosing A Resistive Touchscreen

1. Four-wire vs. five-Wire

Resistive touchscreens are often classed as four-wire or five-wire, depending on the technology used to detect touch instructions. Both four-wire and five-wire resistive touchscreens can read and react to your touch requests. On the other hand, five-wire resistive touchscreens have all of the electrodes on the bottom layer. On the other hand, four-wire resistive touchscreens have electrodes on both the bottom and top layers. As a consequence, five-wire resistive touchscreens outlast and outperform their four-wire equivalents.

2. Material

You should also examine the material used to make a resistive touchscreen. Pay close attention to the material employed in the device’s various layers. Two layers of glass are used in specific resistive touchscreens. On the other hand, others have a layer of glass and a layer of plastic. Glass layers provide superior visual clarity. On the other hand, plastic coatings are stronger and more resistant to breakage.

3. Moisture Resistance

If you want to use resistive touchscreens outdoors — or in other severe conditions — you should consider selecting a device that is moisture resistant. The good news is that most resistive touchscreens are designed to keep moisture out. Specific resistive touchscreens are more suited to damp or otherwise hostile situations than others.

4. Display

What kind of display technology is used by the resistive touchscreen?

A liquid-crystal display (LCD) has emerged as the dominant display technology in touchscreens, and resistive touchscreens are no exception. Although cathode-ray tube (CRT) displays are still used in touchscreens, LCD technology offers better visuals, making it the favoured option among touchscreen users and manufacturers alike.

Things You Didn’t Know About Resistive Touchscreen Technology

Capacitive touch-sensing technology is not used in all touchscreen devices. In recent years, capacitive touch-sensing technology has overtaken resistive touch-sensing technology as the dominant touch-sensing technology for tablet computers, cellphones, and other touchscreen devices. It’s quick, efficient, simple to use, and very adaptable. On the other hand, some touch screen gadgets employ resistive technology to recognize touch instructions. This piece will look at five facts regarding resistive touchscreen technology and how it works that you probably didn’t know.

1. It Supports a Stylus

Using a stylus is a significant benefit of resistive touchscreen technology. With a resistive touchscreen device, you may use your naked finger, a gloved finger, or a pen.

2. Fewer Erroneous Commands

When utilizing a resistive touchscreen device, you will encounter fewer erroneous instructions. Capacitive touchscreen devices are very responsive, thanks to their ability to recognize touch inputs. Even a mild touch will register as a touch command. Resistive touchscreen systems are less responsive because they recognize touch instructions depending on pressure. This is beneficial since resistive touchscreen devices will record fewer incorrect instructions.

3. Increased Precision

You may be shocked to hear that resistive touchscreen devices provide more accuracy than capacitive. This is because resistive touchscreen devices need a stylus. You may also use a stylus to touch certain portions of the UI swiftly. You will sense a greater size if you use your finger to operate a capacitive gadget. You can touch a smaller and more specific region using a pen to operate a resistive device.

4. It Uses Multiple Layers

Although there are several methods to construct a resistive touchscreen device, most have three or more layers. The most typical configuration has an upper and lower layer of flexible material separated by central air or inert gas layer. When you push your finger or pen against the interface, the top and lower layers make contact, enabling the device to recognize your point of contact.

  1. What are the parts of the LCD screen?
  2. Different types of liquid crystals have very different costs
  3. Different glass materials will also lead to different costs
  4. Different glue will also lead to different costs
  5. Different polarizers will also lead to different prices
  6. Different display types will also have big price differences
  7. Different glass thicknesses will also lead to different prices
  8. Different silk printing requirements will also lead to different prices
  9. Some other factors affect the price
  10.  Conclusion

Are you confused and thinking, why is the price of the same LCD produced by different manufacturers so different?

Well, we’ll try to explain everything in this article; we need to know how to get a new LCD design before talking about the factors that influence LCD price.

When some companies want to make their new products, they need an LCD screen and custom designs for LCD.

First of all, they will have an idea about what they need from the following list:

  • LCD size
  • working temperature, 
  • viewing angle, 
  • connection types, 
  • LCD frames, 
  • need backlight or not,
  •  inner symbols, icons, etc.

1. What Are The Parts Of The LCD Screen?

Some of the components: 

  • Diffuser
  • Polarizer
  • Color filter
  • Power supply. The power supply is responsible for supplying electric current to every component of an LCD screen.
  • Backlight
  • Inverter
  • The motherboard of the LCD screen
  • The array of liquid crystals

2. Different Companies Have Different Types Of Liquid Crystals. 

Other companies produce various crystals determined by the different working ranges with very different costs. Different liquid crystals will determine the lifespan of LCDs and the working temperatures of LCDs. 

3. Different Companies Use Different LCD Glass Materials 

Different companies use different LCD glass materials that will lead to different costs. Different glasses for the liquid crystal display will also determine LCD’s lifespan. High-quality and better glasses can keep the LCD safe from scratches and damages. 

4. Different Types Of Glue Used By Various Companies Will Lead To Different Costs For LCD

Glue is essential for the long life of the liquid crystal display. Different types of glue used by different companies will lead to different costs for LCD. Better glues can keep the LCDs having a longer lifespan too. And It keeps the LCD stronger, or it will help the LCDs not easily break. Remember that worse glues may only work for 1 or 2 years and lose their functions. 

5. Different Companies Add Different Kinds Of Polarizers. 

Polarizers play an essential role in the price of liquid crystal displays as they will vary a lot so lead to different prices. That’s why different companies have different prices for their products. Remember, transmissive, transflective, and reflective LCDs use other polarizers from different companies. Reflective and transmissive are cheaper than transflective as it is expensive enough.  

6. Different Display Types Will Have Big Price Differences. 

The key part of the LCD screen is a display type because the display types will determine which kind of liquid crystal will be used. If we look from cheap to expensive is TN, HTN, STN, VA, FSTN(CSTN and DSTN are all FSTN, so we treat them as one kind). So if different companies will use STN instead of TN for the display, the price will be high ultimately.

7. Different Glass Thicknesses Cause The Different Prices

Generally speaking, glass thickness typically has three tiers of LCD, 1.7mm, 2.0mm, and 2.8mm. And the price from low to high is 2.8mm, 2.0mm, 1.7mm. Because producing the thinner display is the most difficult for the manufacturers, it will have a higher defective rate.

The 2.8mm is the most common thickness, the thinner, the more expensive it. Different companies will use them accordingly, and the price will vary from low to high.

8. Different Silk Printing Requirements Will Also Lead To Different Prices.

If you need different silk printing, it will cause different prices because one color silk printing is easy, then two colors than three colors and 4 and 5 and will cost you more if customers need different colors, the more expensive because it will be much more challenging to print different colors. 

9. Some Other Factors Affect The Price Of Liquid Crystal Display. 

Other factors like pin length and pin shapes etc., and particular size and special deals with edges of LCDs will cost much more. 

Factors that influence the price of LCD:

And all these factors listed below are also the most critical factors that will influence the price of LCD. The important factors are the following:

  • Unit Price
  • MOQ (minimum order quantity)
  • Backlight
  • Tooling Fees

 

1. Unit Price

Usually, people have confused about the unit price of custom LCDs. But it’s easy to know the approximate cost of them.

Let’s talk about the factors that will affect the price.

  • Display Mode

Generally speaking, let’s take an example with the same size, same thickness LCD. The price from cheap to expensive is TN, HTN, STN, VA, FSTN, DFSTN because the viewing angle will be wider from TN to DFSTN.

  • Viewing Mode

Viewing modes include Transmissive, Transflective, Reflective.

Here we also treat other factors the same. Size, display mode. Temperature range, etc.

Reflective is cheapest, then transmissive, then transflective.

  • Temperature Range

Generally speaking, all companies divided temperature ranges into four tiers.

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

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

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

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

And it’s clear that the price is from low to high. Because the requirements for the liquid crystals are different, the higher and lower temperature you need, it will be more expensive.

2. COG or COB or LCD only

Why we talk about the LCD frame is because it’s an essential factor that influences price.

COG means chip on glass, and we need to get a suitable IC for it. Because the IC is on glass, it has more production processes requirements. So it will be expensive.

COB means chip on board, there is a lot of space for a big IC to drive the LCD, so the producing requirements are not that fierce.

LCD only is easy to understand the reason. Because we only need to produce the glass and bond the PINs or FPC or conductive tapes on it.

We don’t talk about COF because COF is commonly used in TFT screens. And here we talk about monochrome LCD only.

  • Segments It Needs To Display

It is also easy to understand the meaning of the title. The more segments, the more liquid crystal materials are needed, and the more PINs are required. So under the same conditions, the more segments, the higher the price.

  • PINs

Actually, this part can be combined with the 5th point. More segments you need, more PINs you will need. Then the price will be higher.

  • LCD Size

LCD size is the most important factor that will influence the price of LCD. It’s easy to understand. The bigger it is, the more expensive it is.

3. MOQ (Minimum Order Quantity)

The reason why there will be MOQ should be explained in more detail.

First, making a new mould to make LCDs will change a whole production line for a new item. A production line includes more than 40 processes. And once it starts running. It will take a few minutes to adjust the whole production line and need to use raw materials to test the preciseness of the production line. It will cost a lot when starting production.

And once we changed the whole production line for a new item. It also takes some time to change the moulds. So it’s also a high cost for that.

4. Backlight

Typically, 90% of customers who need LCD will also need a backlight. Because only reflective LCDs don’t need a backlight.

There will also be a massive difference in the price of the backlight. Under normal circumstances, we divide the backlight into three types. The first very commonly used backlight is directly connected to the LCD and soldered on the motherboard. This backlight does not require a specific structure, and its size only needs to be designed according to the size of the LCD and PCB board. The second is the backlight that is attached to the LCD. Generally, we will help it design a wall so that the LCD and the backlight can be better fixed together so that the entire module structure can be more stable. The third is to add an iron frame to the second one, making the structure more stable and helping protect the LCD screen.

5. Tooling Fees

And the tooling fee also has significant differences between the different kinds of LCD and backlights you need.

Tooling fee for LCD from cheap to expensive is TN, HTN, STN, VA, FSTN, DFSTN.

Tooling fee for backlight from cheap to expensive as discussed, the more complex the frame is, the more expensive it will be.

And tooling fee for PCB board. The more extensive and more complex it is, the tooling fee will be higher.

10. Conclusion

The price of different companies can be different because of varying liquid crystals, different LCD glass, different diffuser films. Moreover, different compensation films and pin assignments can use bad bronze. FPC can use inventories or not-good bronze materials. Conductive tapes can also be different, and the material will determine the conductivity. Backlight can be different because of different LED beads, compensation film, and Light guide plate material.
