Indoor LED display is a new type of large-screen display device that mainly displays information by controlling the display mode of semiconductor light-emitting diodes. This kind of display screen uses ultra-high brightness light-emitting diodes as light-emitting elements, and uses electron beam tubes to control high-precision gray scale and white field uniformity to form a high-definition display screen. It has the characteristics of high resolution, delicate pictures, and rich colors, and can be widely used in many fields such as financial securities markets, advertising media agencies, management departments, and sports venues.
