About the knowledge of LED screen
With the passage of time and the development of science and technology, the trend of LCD screens in the market is very widespread, and the hot sales of LCD screens are very strong. There are also many types of LCD screens.
What is an LED screen?
Direct LED: This is composed of LED screens, with LED dioceses placed on the back and have direct effect on the air. This is a screenshot of good images and good keyboard.
Edge-lit LED: This enables the use of LED diodem in the edge of the document, resulting in a layer of salt or oil droplets. This enables blinking of monitors and sparking more energy.
MicroLED: A new generation of LED documents using microscopic LED diodes that can be created by individual forces. This is usually made up of screens, and better robots, and is usually in large screens such as busters, trails, or magnifiers.
The luminous principle of LED lights
LED is a semiconductor device that emits light by injecting electrons and air into the semiconductor material. When they recombine, they release energy and produce photons, thereby achieving light emission.
Composition of LED lights
LED lights are composed of light-emitting chips, packaging materials, leads, and brackets. Among them, the light-emitting chip is the core component of LED lights, and the packaging material is to encapsulate the light-emitting chip in the shell. The leads and brackets are used for connection and fixation.
Composition of LED Display Screen
An LED display screen is composed of many LED lights, each of which is a pixel that can emit light of different colors. These pixels are arranged in a certain way to form a matrix, forming the display area of the LED display screen.
Control principle of LED display screen
The control principle of LED display screen is to convert the signal into the brightness and color of LED lights through the control circuit, thereby achieving display. Specifically, the control circuit of LED display screen includes two parts: scanning circuit and driving circuit.
The scanning circuit is responsible for converting the input signal into the brightness and color of the LED light, while the driving circuit is responsible for transmitting these signals to the LED light and controlling its emission.
The display effect of LED display screen
The display effect of an LED screen depends on the brightness, color, and arrangement of the LED lights. The brightness and color of LED lights can be adjusted through control circuits, and the arrangement can be customized according to needs.
