Generally speaking, the
LED display with black light is more contrast, the color is softer, and the white balance is better. When the screen is not lit, the whole screen looks more beautiful. The first LED network below will introduce you to what is a black LED display.
To understand the black LED display, you need to understand the concept of white light.
The LEDs are assembled from plastic holders and illuminating wafers. Due to the low brightness of the early illuminating wafers, engineers have made the plastic holders into a white bowl shape to enhance the focusing and reflection, so as to ensure that the wafers with low brightness achieve a brighter effect. But white light also has shortcomings. When it is black or gray, his light-emitting diode color (white) also participates in the color to be expressed on the electronic display, which produces color distortion (cannot express black, gray, dark green, etc.) ). Engineers compensate for the lack of brightness in the form of loss of color expression.
What is a black light LED display
Now, when the brightness of the LED is getting larger and larger, the LED tube can be used without a white color to achieve a satisfactory result. In order to meet people's requirements for image fidelity, LED display packaging manufacturers led by Cree began to develop black LEDs to improve the contrast of LED displays.
The difference between the white light (left) and the black light (right) is shown in the figure below.
The difference between black LED display and white LED display
In summary, the black LED display is a display made of a plastic LED with a plastic bracket. Compared with the general LED display, the black LED display has higher contrast and the background color of the whole screen is more uniform.
