LCD Monitors Are Classified By Drive Method

From the driving method of the liquid crystal panel, the most common one is the TFT (Thin Film Transistor) type driver. It achieves independent and precise control of each pixel by means of active switching, so it can achieve a more detailed display effect than the previous passive driving (commonly known as pseudo color). Therefore, most liquid crystal displays, LCD TVs, and some mobile phones use TFT drivers. The liquid crystal display uses a narrow viewing angle TN mode, and the liquid crystal television uses a wide viewing angle IPS mode. They are commonly referred to as TFT-LCDs.

The TFT-LCD is mainly composed of a fluorescent tube (or LED Light Bar), a light guide plate, a polarizing plate, a filter plate, a glass substrate, an alignment film, a liquid crystal material, a thin mode transistor, and the like. First, the liquid crystal display must first use a backlight to project the light source, which will pass through a polarizing plate and then through the liquid crystal. At this time, the arrangement of the liquid crystal molecules changes the polarization angle of the light propagating through the liquid crystal, and then the light must pass through the front color filter film and the other polarizing plate. Therefore, we can control the intensity and color of the last appearing light by changing the voltage value applied to the liquid crystal, so that the color combination of different color tones can be changed on the liquid crystal panel.
