Many of our families now use lcd tv, and how many people know how his lcd screen works. Today, xiaoxi will share the working logic of lcd and related knowledge。
The working method of the lcd screen is to rely on the placement of the lcd screen in the middle of the glass with the ability to conduct electrically, so that there is an electric field reaction between the two electrodes, and the distortion of the lcd molecules creates an electromagnetic effect, thus regulating the effects of light-source projection and shielding, leading to dimness through power control buttons, so that the display screen can show the effects of images, which would be coloured if we were to install colour filters。
When we think that two glass glass is basically fitted with an orientation membrane, then the liquid crystal will go in the direction of the underlying groove, because the groove of the glass base sheet is too high at 90 degrees, so the liquid crystal molecule will form a reverse form, and if the electric field is not installed on the glass floor, the liquid crystal molecule will be transformed into a column, and the light will be shielded from the sub-spectrum of the light, because the niche of the liquid crystal molecule is kept in its original direction, and the light will be absorbed so that it is impossible to see through, and the surface of the liquid crystal will turn into black, the liquid crystal display is based on whether there is a voltage, so that the panels will be shown。
The evolution shown by lcd
The main composition of the liquid crystal is an organic compound, which was created in 1888, when it was in a state of discomfort, hovering between solid and liquid, not only solid substances but also the special characteristics of liquid substances, so it is called a liquid crystal, which consists of an organic compound, the main part of which is a carbon-based compound, and the case of a deviation of the 1963 liquid crystal from the power field was discovered by the united states company william, who also discovered that there would be a reflection of light when it was exposed to the liquid crystal
In 1968, five years after william learned that there would be a reflection of the lcd, the world's first screen was created using the special performance of lcd. The lcd and the monitor were linked and the lcd monitor were called out. In 1968, the lcd was first created, the work of the monitor and its instability were far from being used in our real life, and by 1973, the manufacture of the lcd using benzene was discovered, and since then the lcd was used in many areas. And there's a computer screen。
The liquid crystal display screen is very small for human radiation, and it protects our eyesight, and we all deserve such an environmentally friendly product。
