Some customers report that it feels curious to see a black light LED display in the market, because most of the displays on the market today are white. In fact, this is a packaging technology that is different from white light LED display. As for the specifics, what is the difference between the two? Here we have collected some information, hoping to resolve everyone's doubts.
 
First, the concept
 
1. White LED display
 
LEDs are assembled from a plastic holder and a light-emitting chip. Due to the low brightness of the early light-emitting chips, engineers made the plastic holder into a white bowl shape to enhance the focus reflection to ensure that the less bright chips achieved a brighter effect. However, the white light also has disadvantages. When it is required to express black and gray, the nature of the light-emitting diode (white) also participates in the color to be expressed by the electronic display. ). Engineers make up for the lack of chip brightness by losing color expression.
 
2, black light LED display
 
At present, when the brightness of LED is getting larger and larger, the LED tube does not need to be made white to achieve satisfactory results. In order to meet people's requirements for image fidelity, some manufacturers began to develop black light LEDs to improve the contrast of LED displays.
 
To sum up, the black light display is a display made of encapsulated plastic brackets for black LEDs. The black light display has higher contrast, and the background color of the entire screen is more uniform.
 
As customers have higher and higher display requirements and the continuous improvement of LED display technology, black light LED display will become one of the market products, we wait and see.
