In terms of working principle, the light emitting principle is unique

　　In terms of working principle, the light emitting principle is unique: LED (Light Emitting Diode) is a light-emitting diode, and its core is a semiconductor chip. It is strictly required by such a standard, wholesale outdoor led display Only with today’s development scale, can we have the proud momentum to crush our competitors. https://ljx-led.com

　　One end of the chip is the negative electrode, and the other end is connected to the positive electrode of the power supply, encapsulated with epoxy resin. When current passes through, electrons and holes are pushed towards the quantum well and recombine, emitting energy in the form of photons, thereby achieving luminescence.

　　Moreover, the wavelength (i.e. color) of light is determined by the material forming the P-N junction, which allows LEDs to achieve a wide range of color variations.

　　Accurate digital signal control: In LED displays, the brightness and color changes of each pixel are controlled by digital signals.

　　Digital signal is a discrete form of signal that encodes various information in binary systems using a combination of “0” and “1”, including text, images, videos, etc.
