Key Functions of Each Component Of TFT-LCD Modules

Looking for durable and high-grade TFT LCD Modules that are easy to use and come with many added features – mainly providing HD quality pictures and displaying information? Different types of China TFT Modules or displays are needed in other applications and for various purposes. Therefore, they are created by using advanced technologies and the latest thousands of color blends to make them effective. 

If you want to give better performance to the role of TFT-LCD display module components, you have to know the functional characteristics of these components. 

The TFT-LCD display module is equipped with a semiconductor switch for every pixel, and its processing process is similar to that of large-scale integrated circuits. Because a point pulse can directly control each pixel, each node is relatively independent and maintained continuously. This design improves the display screen's reaction speed and can accurately control the display grayscale. Therefore, the color of the TFT liquid crystal module is more realistic. 

The functions of each part of TFT-LCD display modules are explained below:

1. Light Diffuser: After the light released by the backlight crosses through the light diffuser, it can be evenly distributed to each pixel.

2. Storage Capacitance: Its capacity is about 0.5PF. Its poles are attached with the transparent display electrode / common transparent electrode. Because the power between the transparent display electrode and the common transparent electrode is about 0.1PF, It can not hold the voltage until the next time the image is updated, so it must be maintained with the help of storage capacitance. 

3. TFT: Thin film transistor, a switching device that decides whether the liquid crystal is charged or not (the thin film transistor only switches on or off, and when the thin film transistor is on, the voltage is producing from its source, Charge the liquid crystal and storage capacitor, the LCD driving circuit determines the charging voltage).

4. Row Electrode: The scanning electrode, also recognized as the gate bus, is attached to the thin film transistor gate in each subpixel.

5. Column Electrode: The signal electrode, also known as the channel bus, is attached to the drain of the thin film transistor in all subpixels. 

6. Polarized Glass Plate: That is, a polarizing plate, internal polarized glass plate 1 is horizontal opening, external polarized glass plate 2 is vertical opening.

7. Glass Bottom Plate: Used for isolation.

8. The Transparent Display Electrode: It is combined with the source of each thin film transistor. It makes a charging electrode with the common transparent electrode to charge the liquid crystal in each pixel. 

9. Color Filter: It is also recognized as a color filter, is a glass made up of many transistors. The LCD screen displays a color image, which is generally achieved by joining a color filter between the common transparent electrode and the polarized glass plate. When the light moves through the liquid crystal layer, it moves through the color filter. Because the color filter is organized horizontally in red, green, and blue, the R, G, and B colors are split into three independent points, each corresponding to one sub-pixel. On the contrary, the adjacent R, G, B points have various gray changes and form one pixel simultaneously, and many pixels have different gray changes. Thus, from the principle of color mixing and space addition, we can view a color picture.
