Through CSP LED and quantum dot technology to solve the bottleneck of LED miniaturization

Since the consumer electronics giant Sony in June after the release of the CLEDIS display in North America, the combination of small screen LED display combined with Micro LED technology has attracted market attention. However, LED is facing the challenges of high cost and different wavelength.

At this stage, small spacing LED display applications in the indoor 100 inch -150 inch has matured. However, in the current technology, PLCC's LED package size limit of about 0505 (mm). If you want to do more than 100 inches below the small spacing LED display, LED micro on the cost and wavelength are facing a challenge. At present, the production level of the general blue wavelength uniformity is 5~12nm, while the small spacing LED wavelength is a target of 3~4nm. In addition, when the LED package sizes continue to shrink, in order to avoid the wire caused by the increase in volume of red LED from vertical (Vertical) modified flip chip (flipchip), the cost even more than the blue LED and green LED was doubled in the small pitch screen the sum of the costs of.

LED epitaxial crystal electric manufacturers (Epistar) break the limitation of the approach, it is a combination of CSP and quantum dots (QD) technology, through quantum dot light conversion solution, blue and green LED wavelength uniformity is poor, and the problem of expensive red LED flip chip. Quantum dot crystal electric small spacing LED, package size can be 0303 or even 0202 (mm), distance (pitch) less than 0.5mm. To the resolution of the industry standards, such a LED package, and even can do 60 inches below the small display, is expected to significantly open the application range of small spacing LED display.

Hosted by LEDinside LEDforum 2016, will be held in September 30, 2016 at the International Conference Center, NTU Hospital, the seminar was invited to the deputy general manager of crystal electric R & D center Mr. Xie Mingxun and share his on quantum dot innovative technology in view and Prospect of small spacing display applications.

Conference briefing

LED backlight market tightening, lighting profit bleak, the industry is facing the problem of inadequate nutrition, OLED and apple light swept through, a large layout display applications and special lighting market. However, the LED industry in this difficult time with a new possibility, Micro LED with apple and Sony layout, gradually surfaced, jump into the mass production technology may enter the public life. In view of this, LEDforum2016 will be unveiled Micro LED, "the next generation of display technology on Micro LED and LEDinside, invited the industry advanced, professional analysis team, discusses the future market potential and technology development.

Hosted by LEDinside LEDforum 2016, will be held in September 30, 2016 at the International Conference Center, NTU Hospital, this seminar will explore from the Micro LED material, manufacturing, system integration, and then to the terminal application and market to conduct a comprehensive analysis of the industry, we sincerely invite Gongxiangshengju, visit to.
