Difference between white light LED and black light LED display

Some customers report that it is very curious to see a black LED display in the market because the display on the market is mostly white. In fact, this is a difference from the white light LED display packaging technology. As for what exactly is happening, what is the difference between the two? Here we collect some information and hope to solve everyone's doubts.

First, the concept 1, white light LED display LED is assembled from plastic brackets and light-emitting chips, early light-emitting chips due to low brightness, so engineers will make a plastic bowl made of white bowl-shaped reflector to enhance the focus to ensure brightness Not high wafers achieve brighter results. However, the white light also has its disadvantages. When it comes to black and gray, his light-emitting diode color (white) also participates in the color to be expressed on the electronic display. This causes color distortion (no expression of black, gray, dark green, etc.). ). Engineers compensate for the lack of brightness of the wafers by losing color expression.

2, black light LED display Now, when the LED light intensity is getting bigger and bigger, the LED light 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 LED to improve the contrast of LED display.

Second, the white light and black light LED display distinction <br> <br> mechanized, the package is the use of black light display black plastic holder made in LED display. The black light display has a higher contrast ratio and the overall background color is more uniform.

With the increasing demand of customers for display, LED display technology continues to progress, black LED display will become one of the mainstream products in the market, we will wait and see.
