High contrast

By optimizing the LED chip arrangement and drive circuit, COB LED displays can achieve higher contrast and provide better visual effects.

Uniform light distribution

COB packaging technology eliminates the gaps between multiple LEDs, distributes light evenly, and reduces light spots and chromatic aberration.

Good thermal conductivity

Since multiple LED chips are closely arranged on the same chip, COB technology is beneficial to heat dissipation, reducing the operating temperature of the LED display and extending the service life of the LED.

Application scenario analysis

Commercial advertising

The high brightness and high contrast characteristics of COB LED displays make them ideal for commercial advertising. Whether it is an indoor or outdoor environment, COB LED display can provide excellent visual effects and attract the audience’s attention.

Sporting events

Sports events usually require high-definition, high-refresh-rate displays to present game images. The high refresh rate and grayscale control capabilities of COB LED displays can meet this demand and provide viewers with a smooth viewing experience.

Stage performance

Stage performances require rich colors and dynamic effects to create atmosphere. The uniform light distribution and high brightness characteristics of the COB LED display can present delicate pictures and vivid colors, bringing an immersive viewing experience to the audience.

Conference and Exhibition

Conference exhibitions need to present a variety of information and images clearly and accurately. The high definition and high contrast characteristics of COB LED displays can ensure accurate communication of information and improve audience participation and satisfaction.
