White LED Display vs Black LED Display:Which is Better?

In the purchase of LED display, our eyes are focused on the display effect of the screen, few people will notice that the screen LED lamp bead color is not the same, some are white, some are black. Today we are going to talk in detail about the difference between white LED display vs black LED display and which one is better.

What is white LED display?

When it comes to white LED display, people may confuse it with monochrome LED display with all white color. However, the white LED display we are talking about today is not the same as the white LED bead display and the other single white color LED display.

The single white color LED display is mainly made using DIP packaging technology, the lamp beads are very large with pins, while the white LED display is mainly made using SMD technology packaging, the lamp beads are smaller and fit perfectly with the PCB board.

What is black LED display?

Similarly, a black LED display refers to an LED display where the LED beads are black. It is designed to compensate for the distortion of color that occurs when white LED displays show black images.

Difference between white LED and black LED display

Shape and size

From the appearance, we can clearly see that the white LED display beads are white, while the black LED display is gray.

Through the naked eye, it will seem that the white LED display beads are larger. In fact, white LED display and black LED display lamp beads are the same size, only due to the influence of the mask to interfere with our vision, so it will feel that the white LED display is larger.

Contrast ratio

The contrast ratio of black LED display is 10,000:1, while the contrast ratio of white LED is only 3,000:1. Therefore, the black LED display is very effective in showing pure black, a feature that cannot be fully realized by white LED display.

Stability

Compared with white LED display, black LED display has better stability. This is because black LED display in the performance of black or gray, without additional processing of the image, reducing the stimulation of the LED lamp beads, so the stability is good, long service life.

Brightness

Although black LED displays are excellent in all aspects, they are not as bright as white LED displays. Because black LEDs are non-reflective, it is more difficult to achieve high brightness or pure white color, so there is no way to compare with white LEDs.

Energy consumption

If applied to a full color display, the capacity consumption of both is about the same. Black LEDs consume 350/² and white LEDs consume 380/㎡. However, when displaying a black or white screen, the energy consumption of the two can be significantly different.

Black LED displays can use less power to achieve a black or gray effect, making them superior when displaying black images.

On the other hand, when displaying pure white or high brightness images, black LED displays not only consume more power, but also perform slightly less well.

Cost

From the above several features for comparison, we can find that the black LED display is more powerful than white LED display, so the price of black LED display will be more expensive than white.
If customers want to choose a lower price LED display, then white LED display can also be an alternative.

Which is better, black LED or white LED display?

From the trend, more and more screens are using black LED display. The reason why black LED display is better than white LED display. One is because of the performance of the black LED display, and the second is that the single application of pure white or high brightness is relatively rare, so the black LED is obviously better.

Let’s look at a few more features of black LED display:

Black LED display effect is more delicate

The image performance effect of the LED display has a lot to do with the contrast ratio and color degree. The higher the contrast, the image can achieve a better sense of hierarchy, the picture is more vivid and delicate. We can see from the previous contrast difference comparison, the black LED contrast is much higher than the white LED, so the display effect is much stronger.

Black LED display is clearer

When we use PS to adjust the highlights of the image, we will find that the highlights of the dark areas of the enhancement effect is very obvious. This applies to the display is the same. Black LED display in the performance of the dark area, the level is clear, the picture will be clearer, more recognizable.

Good color uniformity

Due to the non-reflective properties of black LED display, it can better absorb other external stray light, so the color uniformity is better, and it is not easy to be interfered by other colors.

Summarize

We have comprehensively compared the differences between black LEDs and white LEDs and elaborated on the reasons for the superior performance of black LEDs. Although the price of black LED display is slightly higher than that of white LED display, but with its superior performance, it has been more and more widely used.
