Narrow Pixel led display GOB technology is rising
At present, domestic LED companies in the narrow pixel led display package production, not only adhere to the use of GOB technology, Lehman Optoelectronics, Changchun Xida Electronics, etc., and more is to take the four-in-one, six-in-one route.
From LCDs, OLEDs to narrow pixel led display, the new display industry is experiencing dramatic changes, and the competition for different technology routes has made this display battle exceptionally exciting.
With the characteristics of low power consumption, ultra-high-resolution, high color and so on, the micro LEDs that have emerged in the past two years have attracted the attention of international giants including Apple, Samsung, Sony, etc., and have begun to feel the general lighting and After the low-end domestic LED companies that display the market chill are even more unwilling, many LED display companies have launched related narrow pixel led display LED products.
It is understood that at present, domestic LED companies in the HD LED Display package production, not only adhere to the use of GOB technology, Lehman Optoelectronics, Changchun Xida Electronics, etc., and more is to take the four-in-one, six-in-one route.
According to the new high-tech display, the current international Samsung and Sony Micro LED products are also taking a technical route similar to GOB. The representative of this route in China is Lehman Optoelectronics.
"Lehman's Small pixel led display adopts the self-developed new generation COB technology. It solves the pain point of SMD discrete device LED small-pitch display technology. It is an innovative technology that combines LED package and LED display. This multi-LED The chip-integrated packaging technology, the biggest difference from the SMD packaging process is the elimination of the bracket, and also saves the process of lamp reflow soldering during the display production process." Tu Menglong, director of Lehman Optoelectronics Technology, said that the high-definition display product based on GOB technology It has the technical advantages of high density, high protection, high reliability, high adaptability, high image quality and low cost of use. Compared with SMD small pitch products, the failure rate is greatly reduced, which prolongs the service life and reduces the use cost.
It is understood that Lehman Optoelectronics COB products are used in the formal or flip-chip 100-200 micron LED chip, using "single" and "multiple" chip transfer technology on the PCB substrate. At present, the yield can reach 95%, and it is expected to further improve.
Tu Menglong believes that the LED display panel of GOB display technology has higher protection performance, higher reliability, higher contrast ratio, better image quality, more flexible and quick stitching and higher environmental adaptability. .
Many industry insiders who have accepted the interviews of senior executives also agree with this view. Some insiders predict that GOB products in the next one or two years are expected to occupy half of the field in Fine pixel led display.
According to market sources, Liard, who is taking the four-in-one package route, is also developing GOB-type Mini LED small pitch products.
"In the past, GOB was worse than the four-in-one in terms of display consistency. However, with the maturity of the calibration technology, the two have basically not seen the gap." Some unnamed industry veterans said that COB is in heat dissipation, failure rate, etc. There are obvious advantages in terms.
The new display field is ushering in a new technology turning point. Technological innovation means that the industry has the opportunity to rewrite the game rules, reshape the competitive landscape, and provide new development opportunities for the latecomers. Narrow pixel led display is giving the LED industry a new upgrade opportunity.
