TFT screen is a thin film transistor type liquid crystal display, and each pixel is driven by integrated thin film transistors, which not only improves the response time of the display, but also accurately controls the color balance, making the color tone of TFT liquid crystal screen more realistic.
2、 The key components of TFT screen.
The key components of TFT screen include LED backlight, light guide plate, diffusion film, prism film, alignment film, optical materials, thin film transistors, etc.
LED backlight
The light of the moon on an LCD screen comes from the light source at the bottom of the screen.
The LCD light source can be a strip fluorescent tube (CCFL) used on the head of a teacher's office, or it can be a light emitting diode (LED).
LCD light sources usually use LEDs to make our screens extra thin. There are generally two ways to place the light source: one is to directly cover the LED on the lower shading plate, such as a computer display screen; Another way is to place the LED on the side of the screen. For example, mobile phone screens.
Light guide plate
The placement method of using LED on the side of the screen for mobile phones may result in some parts being too bright and some parts being too dark. And using the side swing method requires a layer of light guide plate. The function of a light guide plate is to convert linear light sources into light sources, making the light uniform.
Diffusion film
The diffusion film increases the diffusion area of light and makes it gentler, just like how we look at a light through frosted glass, making our eyes much more comfortable.
