LCD display screens use an organic compound that is liquid under normal conditions and consists of the following components:
1. Horizontal polarizer.
2. Color filter.
3. Liquid crystal: Liquid crystal is a special substance.
4. TFT glass: The TFT glass panel is essentially a matrix composed of millions of FT driving tubes and lT0 (transparent conductive metal) controlling the liquid crystal region, also known as an array.
5. Vertical polarizer.
Specifically, an LCD display screen is made of two fast white glass, abbreviated as TFT, but not ordinary glass. It is made of glass with circuit lines, and liquid crystal is injected in the middle. Then, a polarizing film is attached to the glass to display various colors. LCD, abbreviated as LCD, is tied with an IC and an FPC circuit board, which can display various colors.
The soft material on the surface of a liquid crystal display screen is more accurately called a polarizer (PLZ), which has the function of filtering light. If there is no such thing as this layer on the LCD screen, you cannot see any display at all, because when the LCD screen is working, after filtering out the X-direction or Y-direction light, the remaining parallel light cannot be seen with the naked eye without the polarization display of the polarizing film. Polarizing film is a soft and thin material. If there are scratches, punctures, or abrasions, they will not work in production, so be careful when using them.
LCD display screen is a flat ultra-thin display device composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Its main principle is to stimulate liquid crystal molecules with an electric current to produce dots, lines, and surfaces, which are combined with the back light tube to form a picture. The special property is that if an electric field is applied to a liquid crystal, it will change its molecular arrangement. In this case, if it is paired with a polarizing film, it has the function of preventing light from passing through (light can pass through smoothly without applying an electric field). If it is paired with a color filter and the voltage applied to the liquid crystal is changed, it can change the amount of light transmission of a certain color, It can also be vividly said that changing the voltage at both ends of the liquid crystal can change its transparency (but in reality, this must be combined with a polarizing plate).
