The principle of LCD panel display


A liquid crystal display(tv panel/ open cell), mostly by the drive board, power board, high pressure board and liquid crystal panel composition. The drive board is like a person's "brain", which governs the expression of language and behavior. Its function is to control the normal operation of the LCD panel by receiving and processing the external image signal and output the drive signal. Let us introduce how liquid crystal panels work.

The principle of LIQUID crystal display: an electric field is applied to the liquid crystal to change the refraction phenomenon of the liquid crystal, and the polarized light is used to determine the path of the light, thus producing a colorful image.

Liquid crystal panel is composed of liquid crystal, polarizer, filter and glass substrate. In the absence of an applied electric field, liquid crystal molecules behave irregularly. But if the liquid crystal molecules are subjected to an applied electric field, they will be "forced" to behave in a regular way, rather than moving randomly as before. The image is displayed by refraction when light is absorbed into the liquid crystal layer through the polarizing plate.

The main role of the driving plate is to control the arrangement of liquid crystal molecules through changing electrical signals, and then affect the refraction route of light, so as to present different pictures.

So, as the LCD panel of the most important accessories, the role of the driving plate is self-evident.
