The development of GOB microspacing display

　　GOB technology integrates the midstream packaging and downstream display technologies of the LED industry, which saves the cost of brackets and part of the manufacturing process, resulting in higher production efficiency. "The smaller the dot spacing, the greater the overall cost advantage of GOB products. P1.2 products produced using GOB technology and SMD technology are comparable in cost. When the dot spacing is less than P1.2, the overall manufacturing cost of GOB technology is lower than that of SMD technology."

　　In addition to the advantages of process and cost, GOB products also have better performance, such as high protection, high reliability, high contrast, low energy consumption and wide color gamut. "The bad point rate of GOB products in the life cycle is nearly an order of magnitude lower than that of SMD products, which is better able to meet the needs of ultra-high-definition smart display in the 5G era and has differentiated advantages in small spacing display."

　　GOB technology is a chip-level package, and LED crystal particles directly contact PCB board, which increases the available heat conduction area of LED crystals and improves the heat dissipation capacity. At the same time, the chip-level packaging method is "fully covered," meaning that the LED crystals are coated with a 100 percent protective armor, which helps prevent moisture and bumps. GOB small spacing technology features chip-level packaging and full coverage of optical resin. This structure and the traditional table paste lamp beads, in the picture quality has a great difference.

　　The high brightness of LED screens is an advantage, but it is also a disadvantage for indoor applications. High dazzle light, high frequency refresh sense of vertigo, the granular sense of lamp bead table paste, so that the led screen in the face of high-end command and dispatch center such as "close distance, long viewing time" application, especially "easy visual fatigue". The latter is a drawback that many customers find difficult to accept. GOB small spacing technology can eliminate the "visual experience disadvantage" of these traditional LED screens.

　　The emergence of GOB technology brings LED products with small spacing to a higher stage and brings better user experience to the end market. It has been widely used in various application scenarios, including radio and television, high-end conference, big data center, intelligent command center, monitoring center, exhibition, education and teaching, cultural entertainment, telemedicine, home theater and so on.
