COB know-how advancement of major LED show companies
Posted March 13, 2023
COB know-how is viewed as to be the following era of Out of doors led show packaging engineering, and it has built a qualitative leap in phrases of performance and pitch. Though COB engineering has solid technical advantages, due to value concerns, COB products and solutions are at present only oriented to the mid-to-higher-conclude business show industry, and have not achieved a significant sector penetration charge. Likely again a couple decades, the market place share of COB is even Considerably less than 10%.
From the pertinent investigate and progress of some enterprises in COB technological know-how, it can be viewed that the flip-chip COB packaging technological know-how is the innovative route of the present-day layout of COB monitor enterprises. and so on are exceptional.
To this stop, we specifically interviewed important LED screen suppliers to comprehend the recent trends of COB.
LED COB technologies
Lianjian Optoelectronics: produce charge of COB concluded template approach reaches 99.99%
At present, Liantronics has entire COB R&D, design, producing, and following-product sales upkeep capabilities, and has been equipped to achieve chip-stage COB completed module rework, and the approach produce fee has reached 99.99%, which is in the main place in the industry.
At the ISE exhibition not long back, Liantronics also exhibited its VT0.7, VTⅡ0.9 and other collection of micro-pitch products and solutions in the COB location. The state-of-the-art Vmini micro-pitch display screen know-how and micron-scale mild-emitting chips enable the LED display screen to existing a darker black area and larger distinction.
JYLED: Set up COB production heart
3D LED Show has now recognized a professional COB manufacturing center, masking an spot of extra than 800 sq. meters. JYLED’s flip-chip COB micro-pitch show engineering has won quite a few awards, and this product has been commonly utilized in significant-end convention rooms, command rooms, radio and television studios and other scenarios. Owing to the use of flip-chip COB packaging engineering , the product is secure and responsible, can conveniently cope with many environmental checks, and proceeds to work stably.
Cedar Electronics: Has whole mass production capability of flip-chip COB sequence solutions
As the industry chief in COB exhibit know-how, Cedar took the direct in completing the growth of flip-chip COB technological know-how as early as 2013. In 2017, it was also approved for similar invention patents, and done the iterative up grade from official COB to flip-chip COB technological innovation. Cedar also produced the world’s 1st .4mm extremely-significant-definition fine-pitch flip-chip COB 2K splicing display in the nationwide “13th Five-Calendar year Plan” special venture “Ultra-superior-density modest-pitch LED exhibit important engineering growth and software demonstration”.
At the beginning of this 12 months, Cedar Electronics held its 2023 full flip-chip COB innovative product advertising and cooperation trade conference in Hainan. At the conference, Cedar Electronics shown its a number of integrated flip-chip COB integrated packaging processes and main patented technologies for pixel multiplication Mini LED merchandise, and exposed that centered on the flip-chip COB built-in packaging supporting marketplace chain, Cedar has completed the advancement of 75-inch, 85-inch, 98-inch, 120-inch and other sequence of items and has full mass creation capability, and this products is main It was initially produced by international outside LED display giants this sort of as Samsung and Sony, and the entire established of technologies has achieved the international top degree.
