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

一、SMD(Surface Mounted Device)Led Display Screens: 1) SMD Led Displays working principle and appearance: ①Packaging structure: The red, green, and blue chips are packaged together in the same bracket to form a tiny, square dot, which is a complete full color pixel unit. ②Installation method: Surface mount technology is used, pads are prefabricated on the PCB
