Comparison of Black LED vs. White LED

The majority of led beads used in LED displays are white LED, which is typically used in outdoor displays. Black LED, on the other hand, has become increasingly popular in recent years, particularly among small-pitch LED displays and stage background screens. Therefore, why did the business select the black LED? What advantages does the black LED offer?

The white led's "white" indicates a high brightness for viewing from a distance.

The concept of white LED must first be understood before you can comprehend black LED displays. Chips and plastic brackets make up the LED. In order to ensure that chips with low brightness can achieve a brighter effect, engineers transformed the plastic brackets into white bowls to improve focus and reflection. However, the white led has some drawbacks as well. The light-emitting diode's natural color, white, will participate in the color that the electronic display will express when blackness and grayness are displayed, resulting in color distortion (cannot display black, gray, dark green, etc. completely). However, engineers compensated for the lack of brightness by sacrificing color expressiveness in response to demand.

In the past, outdoor commercial advertisement display was the primary application for PTCLed display screens. It was acceptable to lose color to compensate for the brightness because of the long viewing distance and the high brightness requirement of the display screen. High-density, low-pitch LED displays, on the other hand, are getting better and better as LED brightness increases. White LED beads are not required to produce satisfactory results. Black LED was developed simultaneously by domestic LED display packaging factories like Lanke Electronics and foreign LED display packaging factories like CREE and NICHIA in order to meet people's requirements for image fidelity and enhance LED displays' contrast. It has developed the ultimate black LED, capable of providing the market's darkest level.

The black LED's designation as "black" indicates that the high-contrast display has more vibrant colors.


The performance of an LED display is inversely proportional to the grayscale level. The measurement of the difference between an image's brightest white and darkest black is referred to as grayscale. The contrast is greater the larger the difference range. Grayscale is smaller when the difference range is smaller. High grayscale can support colors of all levels and makes it easier to display vivid and rich colors.

Why Does The Outdoor Rental LED Display Make Use Of The Dark Lamp?

The effect of a black LED display is stunning

In terms of the performance of an LED display, the higher the fidelity, and the fidelity is primarily determined by the two indicators of the contrast and color of the image (greater contrast, more color types, better).

The distinction between the brightest white and darkest black in an image's brightest and darkest regions is referred to as contrast. The contrast is greater the larger the difference range. LED Displays with high contrast can display vivid and rich colors at all levels and are easier to use. The brightness and darkness of the display screen can always be clearly seen on the black LED display.

Contrast is more important than brightness in determining an image's sharpness

 Increasing the brightness of an LED display is primarily intended to make screen images, videos, and other content more visible to customers. The human eye's perception of color is greater than its perception of light and darkness, according to studies.

In general, an image that has a higher contrast is brighter and clearer. As a result, more than brightness, the contrast ratio determines the image's overall clarity. It is more important than a bright display.

Additionally, the dynamic video display effect is more affected by contrast. Higher contrast makes it easier for the human eye to distinguish such a conversion process because the dynamic image's light-to-dark conversion is faster.

However, some customers still hold the innate belief that the brighter the better. In point of fact, a brightness level that is too high will not only result in light pollution but will also harm consumers' visual experience and shorten their viewing time; simultaneously, it will result in an increase in operating expenses and an increase in electricity bills.

Black LEDs have a higher contrast than white LEDs

As a result, it is more feasible to increase the contrast of an LED display screen in an outdoor setting to improve the image's recognizability as opposed to blindly pursuing a high brightness, which pollutes light and uses a lot of energy. Under the same brightness, the higher the contrast, the image will be stronger and more vivid, and customers will be able to see the image more clearly.

The black LED display that comes packaged with a black plastic bracket and PPA has non-reflective properties as well. It can absorb stray light from the outside and has a more uniform background color. As a result, black LEDs are better suited for outdoor retinal LED displays than white LEDs.
