At present, LED displays on the market use white lamp beads. However, in recent years, black LED packaging devices (black lights) have appeared, especially in the field of small-pitch LED displays and stage sets. Confused for many first-time users. Here are the two different packaging technologies for you.

Black lamp beads LED display: In order to meet people's requirements for image fidelity, LED display packaging manufacturers have begun to develop black LEDs to improve the contrast of LED displays.

White lamp beads LED display: The LED display is assembled from a plastic bracket and a light-emitting chip. In the early days, the light-emitting chip was not very bright, so engineers made the plastic bracket into a white bowl shape to enhance the focus and reflection to ensure that the brightness is not high. The wafer achieves a brighter effect.

The black lamp beads LED display is a display made of black LEDs with encapsulated plastic brackets. Compared with the general white LEDs LED display, the black LEDs LED display has the following advantages:

1. The contrast ratio is higher, and the background color of the whole screen is more uniform. The contrast ratio of the black tube is 10000:1 and the contrast ratio of the white tube is 3000:1.

2. The stability of the black light is better, the contrast ratio is high, the brightness is low, and the color is softer. The black tube is 1500cd/㎡, and the white tube is 2000cd/㎡.

3. The black light consumes less power than the white light, which is more energy-saving and environmentally friendly. The power consumption of the black tube is 350w/㎡, and the power consumption of the white tube is 410w/㎡.

4. When the screen is not lit, the appearance color is the same, and the display screen is more beautiful.

Through the above comparison, the white light LED display is weaker than the black light LED display in some functions, but in terms of cost, the black light display is more expensive, and the white light has a strong price advantage. Customers can choose to buy black light or white light display according to the actual needs.

As customers have higher and higher requirements for the display effect of LED displays and promote the continuous development of technology, it is believed that black LED displays with higher fidelity will become the mainstream.
