Product Characteristics

The P0.78 4K COB display screen shows unique advantages in many fields with its ultra-high-definition display and advanced packaging technology.


In terms of display performance, P0.78 refers to a pixel pitch of only 0.78 millimeters, which makes the picture details presented extremely fine. Combined with 4K resolution (3840×2160), whether it is for displaying ultra-high-definition pictures, playing 4K videos, or for professional design, medical image display, etc., it can accurately restore the details of the picture, bringing users a delicate and realistic visual experience. Meanwhile, the COB (Chip on Board) technology directly packages the chip on the circuit board, reducing the connection links between the LED beads and the circuit board in the traditional packaging method, improving the stability and reliability of the display screen, reducing the dead lamp rate, and ensuring the consistency and integrity of the picture display.


In terms of protective performance, the application of COB technology enables the display screen surface to form an integrated structure, which has excellent dust-proof, moisture-proof and anti-collision capabilities, and can effectively adapt to complex environments such as outdoor advertising and industrial control scenarios. In addition, the P0.78 4K COB display has a fast response speed and a high refresh rate. When displaying dynamic images, it is smooth without trailing. Whether it is the live broadcast of large-scale sports events or the display of game competition images, it can present a smooth and fluid visual effect.


In terms of application scenarios, it is suitable for high-end commercial displays, command and dispatch centers, medical imaging diagnosis, high-end conference rooms and other places with extremely high requirements for display quality and stability, providing users with outstanding visual solutions to meet the demands for ultra-high-definition and highly stable displays in different scenarios.
