LED dynamic multiplexing pixel technology for COB and COG panels

Chairman Dai Zhiming delivered a speech on the theme of "Development and Prospects of LED Dynamic Multiplexing Pixel Technology Based on COB and COG Panels". In this speech, Mr. Dai shared three aspects: one is the promotion and application of Lamp Video's patented three-pixel dynamic multiplexing technology; the other is Lamp Video's in-depth layout on COB research and development and manufacturing; and the third is Lamp Video's technical route and discussion of different dynamic pixels based on COB and COG.

Lamp Video has always been actively deploying flip COBs to promote the development of Mini/Micro LED fields. The biggest feature of Lamp Video's Micro fully flip-chip common-cathode COB display panel is that it adopts the patented spatial pixel imaging technology with super resolution. The core of this patent is pixel reorganization. Starting from the pixel point, the industry's conventional array pixel layout design consisting of red, green and blue as a group is disassembled and recombined to form a network with monochrome pixels as shared nodes. An efficient structure of matrix."""" The industry's conventional design is to form 27 lamp beads into 9 groups of pixels with a pitch of 1.5625mm; while the Lamp video solution is to disrupt 27 lamp beads and re-form 81 groups of pixels, reducing the pixel pitch to 0.52mm.

COB/COG dynamic pixel multiplexing technology can achieve cost reduction and efficiency improvement by reducing the number of pixels and optimizing algorithms, while virtual physical pixels can achieve complete image display. However, due to factors such as PM driving method, pixels and board space, the display effect will be affected to some extent. In this regard, General Manager Dai proposed his prospects for the development and combination of glass-based and AM driving methods.

Lamp Video's Micro LED COB-related projects have been approved as key funding projects in Shenzhen Technical Public Relations, and have received widespread attention and reports from the industry and media. Lamp Video's three-pixel spatial dynamic multiplexing technology has obtained many domestic and foreign invention patents. It has cutting-edge product technology and design and research and development capabilities, covering many aspects such as unit structure installation, COB packaging film process, COB testing, and image processing solutions. The achievements of three-pixel spatial dynamic multiplexing technology reflect our Lamp Video's leading technical heritage and product advantages in the flip-chip COB product line.
At the conference, President Dai was pleased to announce that our Lampu Video has officially joined the ranks of COB manufacturers, ushering in a new milestone. Brand strength and honorary testimony, Lamp Video has always adhered to the principles of high quality, high character and high taste, and rewarded customer value through innovation. With manufacturing strength and scientific and technological strength, we will always focus on the main channel of the industry, continuously strengthen technological innovation and product research and development, seize the opportunities of the times, and build and present the beauty of the visual world."" Experts said that this event provides a platform for industry exchanges and interactions. Lamp Video hopes to continue to explore with its peers and promote the sustainable development of COB in the industry.
