When the field uses TN mode to drive liquid crystal, the LCD liquid crystal display is Without any electric field, the liquid crystal will not rotate, so that the light source of the backlight module will pass through the liquid crystal and the polarizing plate, thereby causing the display to display an all-white surface, which is generally called, Normally White, and. The related technologies of TN liquid crystal displays have been significantly improved in recent years, and the contrast and color saturation provided by TN liquid crystal displays are also excellent in conventional displays (for example, CRT displays). However, TN liquid crystal display = has a key The shortcoming, that is, the narrow viewing angle range of the TN liquid crystal display makes its application limited. When the VA mode is used to drive the liquid crystal, the liquid crystal display liquid crystal does not add any electric field, the liquid crystal does not rotate # The backlight mode and the light source of the group will be blocked by the liquid crystal without passing through the liquid crystal and the polarizing plate, and the display will have a black surface. Generally speaking, Normally Black, in contrast, the contrast provided by the VA liquid crystal display is higher than that provided by the TN liquid crystal.
