A liquid crystal display is a type of liquid crystal display that does not seem to generate any light to display characters, images, videos, and videos. But it just changed its light. Change to generate any characters, images, etc.
It's a bit about history.
Inventor J. Fergason created the first working American LCD in 1970. Before that, such a screen screen screen screen screen display. A new LCD monitor was introduced in 1971. Although liquid crystals were discovered very early, they were originally used for different purposes. Research, it is possible to find a connection between the increase in voltage and the change of the guardian to ensure the creation of the image. First of all, crystals are used in computing and crystal watch displays. They are used in displays. Today, due to advances in this field, such screens are very popular in computers and many other devices in the world.lcd display manufacturers,specializing in the development and production of LCD monitors. High-quality products, low power consumption, fast delivery, and reasonable price.
Liquid crystal display technology.
An LCD screen is an array of small segments called pixels, which can be manipulated to display information. This type of display has several layers. Two of the panels are made of sodium-free glass material, called substrates, which play a vital role. The substrate contains a thin layer of liquid crystal between them. The panel has grooves to guide the crystals, giving them a unique orientation. The flute is parallel on each panel, but perpendicular between the two. The longitudinal grooves are obtained by placing a transparent plastic film on the surface of the glass and then processing it in a specific way. When in contact with the flute, the orientation of the molecules in all cells is the same. The LCD panel is illuminated by a light source, depending on where it is located, because the LCD panel operates in reflection or light transmission. When a panel passes through, the polarization plane of the beam is rotated by 90°. When the electric field appears, the molecules align along the electric field part, and the rotation angle of the polarization plane of the light becomes 90°. By using LCD display technology to produce screens, the backlight of the display is used to output color images, thereby generating light on the back of the LCD display. Must be able to have high-quality pictures, even if it is dark. The color is obtained using three filters, which distinguish the three main components from the radiation of the white light source
