The LED is assembled from a plastic bracket and a light-emitting chip. In the early days, the light-emitting chip was not too bright, so engineers made the plastic bracket into a white bowl shape to enhance the focus and reflection. This is the white led lamp display. The black led lamp display is a display made of black LEDs with encapsulated plastic brackets.
The LED display uses red, green, and blue light-emitting diodes to express images. If the led screen wants to express black, then its method is to not emit light (because there is no black light in nature). The led display uses white led lamps, its natural color(white) also participates in expressing color, then produces color distortion (cannot express black, gray, dark green, etc.). The main differences between black lights and white lights are:
1. The performance of the black led lamp has been greatly improved in many aspects such as heat dissipation capacity, light decay, color cast problem and contrast ratio.
2. When the black led lamp expresses black or gray, it can achieve higher image fidelity, the background color is more uniform, and the contrast of the LED display can be provided to achieve a good performance effect. At present, the black led screen made by our company also has high brightness which can reach at least 3500nits or more.
3. But for projects installed in special outdoor locations, such as the seaside, highways, etc., The ambient sunlight is strong in this environment, and our white LED lamp led display, with more than 10000nits. The high brightness led screen plays advertisements can attract more people.
