Types of LCD interface of notebook computer

There are three main interface types: TTL interface, LVDS interface and TMDS interface. The board has nothing to do with the LCD screen. The key is to look at your screen. The choice of screen line depends on your interface type, and it depends on whether your interface is single-channel 6-bit, single-channel 8-bit, dual-channel 6-bit and dual-channel 8-bit.

Generally speaking, the longest used interface is lvds interface. If you want to connect, you should operate according to the definition of interface pin. The pin definitions of ttl interface, lvds interface and tmds interface are different, so you should choose according to your screen. If you connect it backwards, you may burn the motherboard or screen.

As for the power supply, the battery has little to do with the notebook. The main thing is to know the rated voltage of your LCD driver accurately and buy the corresponding adapter. If the voltage is too high, it will burn out, and if the voltage is too low, it will not start well.

Extended data:

The LCD screen is based on liquid crystal material and is filled between two parallel plates. The arrangement of molecules in liquid crystal materials is changed by voltage, so as to achieve the purpose of shading and transmitting light, and to display images with different shades. Moreover, as long as a three-color filter layer is added between the two plates, a color image can be displayed.

LCD screen has low power consumption, so it is favored by engineers and is suitable for electronic equipment using batteries.

In a word, the basic principle of screen display is to fill liquid crystal material between two parallel plates.

The arrangement of molecules in the liquid crystal material is changed by voltage to achieve the purpose of shading and light transmission, so as to display images with different shades and patchwork. As long as a three-color filter layer is added between two plates, color images can be displayed.

Knowing its structure and principle, knowing its technical and technological characteristics, we can be targeted when purchasing, and more scientific and reasonable when applying and maintaining. Liquid crystal is an organic compound, which is composed of long rod-like molecules. In the natural state, the long axes of these rod-like molecules are roughly parallel.

The first characteristic of LCD is that the liquid crystal must be poured between two planes with fine grooves to work normally. The grooves on these two planes are perpendicular to each other (intersecting at 90 degrees), that is, if the molecules on one plane are arranged in the north-south direction and the molecules on the other plane are arranged in the east-west direction, the molecules located between the two planes are forced to be in a 90-degree twisted state.

Because light propagates along the arrangement direction of molecules, it is also distorted by 90 degrees when passing through liquid crystal. However, when a voltage is applied to the liquid crystal, the molecules will rearrange vertically, so that light can be emitted directly without any twist.
