With the rapid development of computer network and display equipment, the indoor LED display screen is an electronic display screen composed of LED dot matrix. By turning on and off the traffic light beads, the screen display content forms such as text, animation, pictures and video are transformed in time, and the component display control is carried out through the modular structure.
The biggest difference between LED display screen and traditional LED TV screen is industrial manufacturing. LED TV for the general family, and LED display for industrial engineering. LED TV works continuously for 48 hours, and LED display can play continuously for 365 days. The life cycle of LCD LED screen used in ordinary LED TV is 10000-30000 hours, while the life of backlight of LED screen used in shadow technology can be as long as 100000 hours, which ensures the consistency of brightness, contrast and chroma of each LED screen used in splicing display screen after long-time use, and ensures that the life of display screen is not less than 60000 hours.
After years of development, LED display technology has occupied an important position in the field of LED splicing display. LED display is a kind of flat panel display, which is composed of small LED module panels. It is used to display text, image, video and other information. Full color LED display is mainly divided into display module, control system and power supply system. The display module is composed of LED light lattice, and the screen emits light; The control system is to adjust and control the lights in the area to realize the conversion of the content displayed on the screen; The power supply system converts the input voltage and current to meet the needs of the display screen. Splicing curtain wall is characterized by ultra-light, ultra-thin, long life, low maintenance cost, low power consumption, no radiation, high definition, outstanding advantages, and has attracted much attention. Led splicing wall, with LED display screen as the basic display unit, integrates the latest LED display technology and pure hardware high-speed real-time splicing control (control) technology, all input signals can be freely displayed in the display wall window, and fully supports high-end display functions such as cross screen, roaming, picture in picture, overlay, zoom and so on.
