What is the difference between black and white lights on outdoor LED display screens?

　　1. To understand the outdoor LED display screen with black lights, one must first understand the concept of white lights.

　　LED is assembled from a plastic bracket and a light-emitting chip. In the early days, because the brightness of the light-emitting chip was not high, engineers made the plastic bracket into a white bowl shape to enhance the focus and reflection, so as to ensure that the chip with low brightness can achieve a brighter effect. However, white light also has disadvantages. When it is necessary to represent black and gray, its LED natural color (white) also participates in the color to be expressed on the electronic display screen, which results in color distortion (black, gray, dark green, etc. cannot be represented). Engineers compensate for insufficient chip brightness by losing color expression.

　　2. What is a black light outdoor LED display screen

　　Nowadays, with the increasing brightness of LED lights, LED tubes no longer need to be made white to achieve satisfactory results. In order to meet people's requirements for image fidelity, outdoor LED display screen packaging manufacturers led by Kerui have started developing black light LEDs to improve the contrast of outdoor LED displays.
