What is the mobile phone screen generally made of

Why is the mobile phone screen glass, and what is the difference between the glass used in the mobile phone and ordinary glass!

Usually the mobile phone screen is composed of 4 layers, and the role of each layer is different.

1. The top layer of glass is cover glass, and most of them are made of sapphire material. The main component of sapphire is alumina, which is a single crystal material with a hardness of 9 on the Mohs scale (a standard for mineral hardness), making it the hardest material other than diamond (diamond), so it has a good scratch resistance effect. However, the sapphire material also has shortcomings, such as poor toughness, which is generally said that the material's ability to resist crack propagation is not good.

The toughness of the screen is very important for a mobile phone, and the toughness of sapphire is worse than that of Corning Gorilla Glass, so a phone with a sapphire screen is more likely to shatter when impacted or squeezed by the same force than a phone using Corning Gorilla Glass. In addition, the light transmittance of sapphire material is also low, the brightness of the screen using sapphire material is not high, and the imbalance of transmittance will also make the screen color cast.

In recent years, the cost of sapphire manufacturing has dropped considerably, and the process has become more mature, which has made sapphire screens meet certain requirements in mass production, and changed the disadvantages of "low yield rate and difficult mass production". Therefore, many manufacturers choose sapphire material for cover glass.

2. The second layer is the touch sensor layer, which mainly has two types: resistive type and capacitive type, and its main function is to detect touch operation. The mobile phone screen has a touch-sensitive layer function, which is mainly applied to the glass to apply magnetron sputtering technology to coat a layer of ITO (indium tin oxide, or tin-doped indium oxide), which is a mixture of indium (group) oxide and tin (group IV) oxide.

There are four layers to the phone screen. The top glass of the first layer is cover glass, the main component of which is silica.

To protect the internal structure of the mobile phone, the mobile phone cover glass on the market is mainly Corning.

Production of Gorilla Glass.

Sapphires have appeared technically at the moment.

The material replaces the glass material, Apple uses the sapphire material, the hardness of the material is first-class, and it has more advantages than glass in terms of scratch resistance, but sapphire still has disadvantages in technology, such as its toughness is relatively poor, and the transmittance of visible light is less than 90%, which is easy to make the screen color shift.

The second layer is the touch sensor layer, which is mainly divided into resistive and capacitive type, and its main function is to detect touch operation. Graphene at the moment.

Most likely to become the mainstream material for touch screens. Graphene is the thinnest and hardest known nanomaterial in the world, and it is almost completely transparent and resistive.

It is extremely low and the rate of electron migration is extremely fast, so it is expected to be used to develop a new generation of electronic components or transistors that are thinner and more conductive.

The third layer is the front panel, which is mainly used to install filters and generate images.

The last layer is the backplane, which is used to process millions of thin-film transistors. Whether it is an ultra-thin touch screen or a large-size touch screen, it is actually composed of these parts. Junye Electronic Technology, a brand enterprise focusing on the research and development of touch products for more than ten years, specializing in the development and production of capacitive touch screens, the touch screen produced is very sensitive, scratch-resistant, ultra-clear at high and low temperatures, and will not fail.

From the perspective of industry technology and applicability, the end consumer, especially the majority of mobile phone users, we recommend using LCD screens. Why? Please refer to the following:

1.At present, the mobile and application displays on the market can be divided into LCD and OLED in terms of manufacturing process.

It is the mainstream display**, and the performance gradient is large. There are copycat machine screens with very low resolution, such as general TN screens; There are LTPS screens like LG customized for iPhone, etc., which are of medium and upper quality; There are oxide film screens up to 400ppi, etc.

3.The LCD is enough to display on the phone!!

It has not been used for a long time in mobile phone display, but the technical field has given full affirmation, especially its correction of the shortcomings of LCD products. However, OLED has gone through a long R&D cycle, and the current progress is slow, far from the speed at which LCD replaced CRT in the past. Due to the insurmountable defects in use, the current application is very limited, such as short life, uneven color, immature technology, etc.

5.At present, various display chip factories have OLED projects.

6.At present, the largest OLED manufacturers are the bankrupt Kodak and Samsung Mobile, but Samsung's ace phones all use LCD.

7.My personal opinion is that the applicability should be good! A car doesn't have to be the fastest, clothes aren't the most expensive, and a house isn't the highest. However, everyone is encouraged to buy more OLED products to test their sexual tolerance.

At present, most of the mobile phone screen Qingji is using the following four mobile phone screen materials:

1. TFT screen:

TFT stands for thin-film field-effect transistor, which is a kind of active matrix liquid crystal display. The brightness of the TFT mobile phone screen material is good, the contrast is high, the sense of hierarchy is strong, the color is bright and bright, and the disadvantage is that it consumes more power;

2. IPS screen:

iPhone4 and iPhone4S use IPS material screens. The advantages of this mobile phone screen material are good light transmittance and high touch accuracy. The disadvantage is that the power consumption is slightly higher and the output is relatively low;

3. Super LCD screen:

At present, most of the high-end mobile phones are made of superLCD screen material, which has the advantage of strong comprehensive quality and high cost performance, and the disadvantage is that it is slightly thicker than other screens and consumes more power;

4. OLED screen:

OLED is an organic light-emitting display, which is a new type of product in the material of the mobile phone screen, and is known as a dream display. The advantages of this mobile phone screen material are high contrast, power saving, and high color saturation.
