The “scan” of an LED display refers to the ability of the driver IC to light up the number of rows per unit time, which is directly related to the brightness, refresh rate, stability, power consumption, and production cost of the display screen. Within the same time period, the screen is divided into 32 or […]

一. Pre installation preparation and site survey: 1) Site survey: ①Installation 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 the installation height

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
