ED display (LED panel) is a display screen that displays various information such as text, graphics, images, animations, market prices, videos, and video signals by controlling semiconductor light-emitting diodes.
Through appropriate connections (including series and parallel) of light-emitting diode chips and appropriate optical structures. The light-emitting segments or light-emitting points of the light-emitting display can be constituted. These light-emitting segments or light-emitting points can be composed of digital tubes, symbol tubes, pyramid tubes, matrix tubes, level display tubes, etc. Usually, digital tubes, symbol tubes, and pyramid tubes are collectively called stroke displays, while stroke displays and matrix tubes are collectively called character displays.
