A brief analysis of the difference between the white light LED and the black light LED display
- Mar 22, 2018 -

Some customers have shown that it is curious to see a black light LED display on the market because most of the screens on the market are white lights at the moment. In fact, this is a packaging technology that is different from the white light LED display. What is the difference between the two and what is the difference between the two? Here we have collected some information, hoping to solve our doubts. 1, a concept, a white light LED display LED is composed of a plastic bracket and light emitting chip assembly, early light emitting chips because the brightness is not high, so the engineers will be plastic stent made of white bowl used to enhance reflective focusing, to ensure the chip brightness is not high to achieve a more bright effect. But white light also has its shortcomings. When it comes to black and gray, its luminous two level tube is white, which is also involved in the color of the electronic display, which produces color distortion (not black, gray, dark green, etc.). Engineers make up for the low brightness of the chip with the loss of color expressiveness. 2, the black light LED display now, when the luminance of LED is getting bigger and bigger, the LED lamp has no need of white to achieve satisfactory results. In order to meet the people's demand for the fidelity of the image, some manufacturers have begun to develop a black light LED to improve the contrast of the LED display. Two, the difference between the white light and the black light LED display screen, the black light display screen is used to encapsulate the plastic support for the black LED. The contrast of the black light display screen is higher, and the bottom color of the whole screen is more uniform. With the development of LED display technology, the black light LED display will become one of the mainstream products in the market. We will wait and see.
