Product Characteristics

The P2.5 4K full-color small-pitch COB display integrates advanced technologies and has unique advantages in display performance and application scenarios.


In terms of display effect, P2.5 refers to a pixel pitch of 2.5 millimeters, combined with 4K ultra-high-definition resolution, which can delicately present the details of the picture. Whether it is precise design drawings, complex data charts, or exquisite film and television images, every detail can be clearly displayed. COB (Chip On Board, chip on board packaging) technology directly packages LED chips on circuit boards, featuring high contrast and high brightness. Even in a bright environment, the picture is clear and vivid, with precise colors. The black is deep and pure, the white is bright and clean, and the color transition is natural and smooth. Meanwhile, the refresh rate of this display screen is as high as over 3840Hz, effectively eliminating the flickering and trailing phenomena of the picture. When presenting dynamic videos and performing high-speed picture switching, the smoothness is excellent.


In terms of structure and performance, the COB technology endows the display screen with outstanding protection performance. Its integrated packaging design avoids the problem of easy damage and detachment of the LED beads in traditional SMD display screens. It has strong dust-proof, moisture-proof and anti-collision capabilities and can adapt to various complex environments. Moreover, the display screen has good uniformity of brightness, no dark corners or Mosaic phenomena, and the viewing Angle is close to 180°. The picture effect remains consistent when viewed from different directions.


In application scenarios, the P2.5 4K full-color small-pitch COB display is suitable for high-end conference rooms, command and dispatch centers, radio and television studios and other places. In the meeting room, all kinds of materials can be displayed clearly. In the command center, massive data information can be presented in real time and accurately. In the studio, it brings immersive visual experiences to the audience and meets the display requirements of diverse scenarios.
