What are the total components of a mobile phone LCD

The mobile phone screen is used to display images and colors, so it is also called a display screen.

The screen material, screen color, brightness, contrast, etc. of the mobile phone screen determine the screen quality.

After production is completed, the quality of the mobile phone screen can be verified through testing. Using a large current spring microneedle module as an electronic component for connection and conduction can play a stable connection role and improve the testing efficiency of the mobile phone screen.

If you want to understand the mobile phone screen

You can start with the composition structure of the mobile phone screen. The more colors and more complex pictures the mobile phone screen can display, the richer the levels of the picture.

The mobile phone screen is mainly based on the touch screen. The assembly of the mobile phone screen includes cover glass, touch module, and display module.

NO.1

Cover glass: The outermost component of the mobile phone screen, which plays a role in protecting the internal structure of the mobile phone. In order to prevent scratches on the screen, mobile phone manufacturers usually put a protective film on this layer of the screen.

NO.2

Touch module: It can realize touch sensing and is the key to improving the human-computer interaction experience. Mobile phone screens are basically based on capacitive touch screens. Below the touch sensing layer is the front panel, which is mainly used to install filters and generate images; the next layer is the back panel, which is used to process thin film transistors.

NO.3

Display module: mainly LCD and OLED, which are the two most mainstream types of mobile phone screens. The LCD screen display module is composed of polarizers, color filters, TFTs, liquid crystals, back panels, etc. It has good image color rendering, soft pictures and does not hurt the eyes. It is the most widely used mobile phone display screen at present; the OLED screen display module is composed of polarizers, organic light-emitting layers, glass, TFTs and other materials. The screen can emit light by itself, and has the advantages of being thin, flexible and low in energy consumption. It is an emerging screen display technology.

From the development trend of thin and large screens of mobile phone screens, the production and manufacturing of mobile phone screens is also developing from a single component supply mode to an integrated module, and the requirements for the display clarity and refresh rate of the screen are also increasing. In addition to improving the manufacturing process and technology, testing is also a very important part of the quality of mobile phone screens.

As mentioned above, the high-current shrapnel microneedle module can be used for mobile phone screen testing, so what functions does it have?

First of all, this is an integrated module that has a reliable solution for transmitting large currents and dealing with small pitches. It can withstand a large current of up to 50A and the current flow is stable. The value of the large current shrapnel microneedle module in the small pitch is between 0.15mm-0.3mm, and it has a stable connection function.

Secondly, the service life of the large current shrapnel microneedle module is an average of more than 20W times, and it can pass high-frequency testing. It can maintain good performance even in complex test environments, is not easy to break, and does not need to be replaced frequently. The stable connection function of the large current shrapnel microneedle module can ensure the stable and efficient testing of mobile phone screens, and the long service life reduces the cost of mobile phone screen testing, making it an ideal test connection module.
