Understand the black light LED display and white light LED display

As an important tool for modern information dissemination and publicity, LED display screens have become increasingly diversified in performance and expression. Among them, black light LED display and white light LED display are two common types, and they have obvious differences in display effects and application scenarios.

White light LED display:

White light LED display is a common type of early LED display. LEDs are assembled from a plastic bracket and a light-emitting chip. Early light-emitting chips had low brightness, so engineers usually made the plastic bracket into a white bowl shape to enhance focused reflection and ensure that the light-emitting chip achieves a brighter effect. However, when the light-emitting diodes of the white LED display display colors such as black and gray, because their true color is white, they will participate in the color to be expressed by the electronic display screen, resulting in color distortion, especially when displaying black, gray, dark colors, etc. It doesn't work well with colors like green. LED displays are divided into single-color, dual-color and full-color types.

Black light LED display:

With the improvement of LED luminous brightness, LED lamp tubes no longer need to be made white to achieve satisfactory brightness. Therefore, LED display packaging manufacturers began to develop black light LEDs to improve the contrast and color expression of LED displays. The black light LED display uses an encapsulated plastic bracket in black. Compared with the white light LED display, it has a higher contrast and a more uniform background color of the entire screen, which can present a more realistic and clear image. What should I do if the LED display screen cannot load images?

Summarize:

To sum up, there are significant differences in the packaging of light-emitting chips between black-light LED displays and white-light LED displays. White light LED displays were often used in early LED displays, while black light LED displays were developed with the advancement of technology and have higher contrast and better color expression. Therefore, when choosing an LED display screen, you should choose a suitable type according to actual needs and application scenarios to obtain the best display effect.
