What does mobile phone screen TFT mean?

Mobile phone screen TFT is a common liquid crystal display technology designed to improve the image quality and response speed of mobile phone screens. TFT screens are composed of many micro-transistors. Each transistor controls a liquid crystal pixel. By changing the Electric field to control the degree of light transmission. Compared with traditional LCDs, TFTs use transistors that individually control each pixel to more precisely control the brightness and color of the pixels.

Mobile phone screen TFT (Thin Film Transistor) is a common liquid crystal display technology designed to improve the image quality and response speed of mobile phone screens. The TFT screen is composed of many micro-transistors, each transistor controls a liquid crystal pixel, and controls the degree of light transmission by changing the electric field of the liquid crystal. Compared with traditional LCD (liquid crystal display), TFT uses transistors that individually control each pixel to more precisely control the brightness and color of the pixel.

The basic structure of a TFT screen includes a glass substrate, a light-transmitting layer, a liquid crystal layer, a control circuit and a backlight module. The glass substrate is the supporting structure of the TFT screen. The light-transmitting layer is used to transmit light from the backlight. The liquid crystal layer is a key part. The liquid crystal molecules have two states. The arrangement of the liquid crystal molecules can be controlled by changing the electric field to adjust the transmission of light. degree. The control circuit controls the transistors through signal lines to turn them on or off one by one to control the brightness or color of the corresponding pixels. The backlight module is a key part of providing background lighting for TFT screens, usually using cold cathode fluorescent lamps or LEDs.

One of the advantages of TFT screens is their high brightness and vivid colors. TFT screens produce sharper, more vivid images than traditional LCDs. This makes TFT screens ideal for use in a wide range of mobile phones, computers and other electronic devices. In addition, the response speed of the TFT screen is also very fast, and it can quickly display dynamic images and videos, reducing blur and stretching.

However, TFT screens also have some disadvantages. First, it is relatively thick and takes up a certain amount of space, which limits the design and manufacturing of electronic devices. Secondly, TFT screens are easily damaged when bent or twisted. In addition, TFT screens consume a lot of energy, which has a certain impact on battery life and endurance.

In order to solve the limitations of TFT screens, some new technologies are constantly developing. For example, AMOLED (Active Matrix Organic Light Emitting Diode) screens use organic light-emitting diodes and TFT-like technology to provide higher contrast and faster response speed. Flexible screen technology is also developing rapidly, allowing for thinner, lighter and more bendable screens.

In short, TFT screen is a common liquid crystal display technology used in mobile phones and other electronic devices. It delivers high-brightness, colorful, and fast-response images by precisely controlling each pixel's transistors. Despite some shortcomings, TFT screens are still one of the most common and widely used mobile phone screen technologies. With the advancement of technology, more advanced screen technology may appear in the future to replace TFT screens, providing better display effects and user experience
