The difference between LCD and led LCD
What is the difference between LCD and led LCD? Let Jingyao popularize it today.
Led LCD screen: Also called electronic display screen or floating word screen. It is composed of led dot matrix and ledpc panel. It displays text, pictures, animations and videos through the bright red, blue and green led lights. The content can be changed at any time, each component is a modular display device.
traditional led display screen is usually composed of display module, control system and power supply system. The display module consists of a dot matrix composed of LED lights and is responsible for luminous display; The control system can make the screen display text, pictures, videos and other contents by controlling the on and off of the corresponding areas. Monochrome and dual-color screens are mainly used to play text, while full-color screens are mainly used to play animation; The power supply system is responsible for converting the input voltage and current to the voltage and current required by the display screen.
LCD liquid crystal display is mainly used for mobile phones, medical equipment, etc. The LCD display uses two pieces of polarized material, between which is a liquid crystal solution. When the current passes through the liquid, the crystals are rearranged so that light cannot pass through them. Therefore, each crystal is like a shutter that allows light to pass through and block light.
The above are some of Jingyao's own views on the difference between LCD and led liquid crystal display. Generally speaking, led liquid crystal display is better, however, the price of led is relatively higher, but in some occasions it is suitable to use LCD screen, so it is defined according to the environment and price.
