一. Features and working principle of LED display screens: ①The core technology of led displays is self illumination and each pixel is a miniature led bead. ②Light emission principle is RGB led beads directly mix to emit light. ③The splicing effect is seamless, and it can be spliced ​​in any size, and the physical seams […]

一. Pre installation preparation and site survey: 1) Site survey: ①Outdoor Led Screens Installation location: Determine whether to install on a wall, roof, or freestanding column. Assess the wall structure load bearing wall, hollow brick wall, or foundation conditions. ②Viewing angle and distance: Determine the viewing direction and distance of the primary audience to determine

一、Core Component: Light Emitting Diode led: Leds are the pixels of an led display screen, which are the most basic light emitting units. ①Electroluminescence: When an electric current passes through a special semiconductor material, electrons and holes recombine, releasing energy in the form of photons, thus emitting light. ②Color principle: A single led chip can
