There are many types of LED screens, mainly to adapt to different usage scenarios. For example, the small-pitch display screens we often hear about are mainly used in some monitoring rooms, conference rooms, etc., targeting some high-end LCD monitors, so they have occupied part of the high-end display market.

There are also display screens such as stage rental LED display screens, which are also to adapt to the fluidity and timeliness of stage displays, and to facilitate disassembly and transportation to other places after the performance. Therefore, different screens and different products correspond to different needs. Let's take a closer look at the types of LED display screens.

Types of LED screens: 1. Classification by color Single primary color display: single red or single white; Two-color display: red and green two primary colors, 256 grayscale, can display 65536 colors; full-color display screen: red, green, and blue three primary colors, 256 grayscale full-color display screen, can display more than 160,000 colors.

2. Classification by pixel unit Digital display: display pixels are 7-segment digital tubes, suitable for making clock screens, interest rate screens, etc.; Graphic display screen: display pixels are dot matrix modules, suitable for playing text and image information;

Video display: display pixels are composed of many light-emitting diodes, which can display various video files such as videos and animations.

3. Classification by usage location Indoor display: small luminous points, dense pixel spacing, suitable for close viewing;

Semi-outdoor display screen: between indoor and outdoor, not rainproof, suitable for information guidance on the lintel; Outdoor display screen: large luminous points, large pixel spacing, high brightness, can work in the sun, with windproof, rainproof, waterproof functions, suitable for long-distance viewing. Advantages of LED display screen

1. Natural color restoration
Using the LED light-emitting mechanism and point-by-point correction technology, the color authenticity of the picture can be fully retained, and the color loss and deviation of the picture caused by other display technologies, such as the material of the display, can be completely avoided, and the true color reproduction can be achieved.

2. High brightness and intelligent adjustable Since the brightness of the LED display itself is relatively high, in order to meet the needs of strong light environment and dark light environment, give viewers a more comfortable viewing effect and avoid visual fatigue, the screen brightness can be automatically adjusted in conjunction with the light sensing system.

3. High refresh rate, faster response speed LED display screens, as a commonly used electronic display product, are no exception. The number of times the electron beam repeatedly scans the image on the screen. The more scans, the higher the refresh rate, and the better the stability of the displayed image. Just like when we play games, we generally choose a screen with a higher frequency, so that we will feel the best when playing games; on the contrary, if the refresh rate is low, the flickering and jittering of the image will be more serious, and eye fatigue will be faster. At the high refresh rate of the LED display screen, the shooting picture is stable, there is no ripple black screen, the image edges are clear, and the real information of the image itself is accurately restored
