Crystal power breakthrough next generation LED, the introduction of quantum dots, CSP backlight and display industry

LEDinside day held in front of LEDforum2016, focusing on new technology to change the future of the industry, including quantum dots (Quantum Dot), Micro and LED technology. Because LED is currently in LED backlight market, LED lighting market has been saturated, high growth potential respectively, but different applications need to open problems, the LED industry needs more new applications and directions, including small pitch LED display (advertising billboards, indoor and outdoor large screen), LED, LED (not visible light vehicle UV, IR), plant lighting, has confirmed that it is an important application of sustainable growth in the future, more or less have the opportunity and the technology of quantum dots, and even Micro LED technology integration, the combined effect of play opportunities.

LEDinside LED visited Taiwan Dachang epitaxial crystal electric (Epistar) Deputy General Manager Xie Mingxun, understand the crystal electric in the next generation of LED chip technology has come to the kind of trend, have the opportunity to have more possibilities.

EPISTAR deputy chief Xie Mingxun said that many special applications in the LED industry, EPISTAR has mastered the corresponding technology, and actively develop and solve customer problems.

According to LEDinside data, the LED industry from 2016 to 2021 compound annual growth rate (CAGR) was 2%, showed that the overall explosive growth is not easy to occur, the main LED application market entered the mature period, but more special applications still have high growth potential.

Xie, vice president pointed out that the crystal in special applications, is very optimistic about the application of quantum dot technology on LED, as well as the development of CSPLED backlight LCD TV market in LED. While quantum dyking electricity has developed several years, there has been a matter of course, concerned by the market.

Quantum dot technology blessing small pitch LED display

LED chip products currently in the LED display with the crystal power, not only has the red LED production capacity and technology, patent on the edge, to screen for RGBLED, the spacing of market visibility and market share is very high, rely on the unique miniature chip size, and effectively processing cost and wavelength uniformity. Through the introduction of quantum dots technology in the small spacing LED display screen, the crystal can be used for better color rendering, and the luminous efficiency is also improved.

At present the LED display (LED billboard, LED Display) is mainly divided into indoor, outdoor screen screen and screen the main buyers are semi household, commercial space operators for public space advertising films, advertising posters carousel. In the past, the field of products to low order LED products, LED spacing between relatively large, with the size of the face of the resolution is relatively low, the use of LED is also relatively small.

However, the current LED chip and packaging technology on the market, the size of the chip can be miniaturized LED, crystal power in this area has been recognized by the market, you can narrow the gap between the rendering of LED. As a result, a small pitch LED display can have a higher resolution, the audience can compare and watch with their own eyes, feel quite obvious quality progress, there are more and more high-end market buyers orders.

Thank the vice president believes that the smaller size of LED, representing a large screen before the outdoor, there is the opportunity to do this 100 inch and 60 Inch specifications in the room, FullHD is also zoned high quality, even more high quality products designated 4K, the future will have the opportunity to appear, is a possible option to display industry.

Indeed, small pitch LED display compared to other display technology, self luminous, high brightness, excellent color, easy to maintain and update frequency fast, with characteristics of seamless stitching, stitching in there are large plasticity, in the field of large screen display, no other technology can match. The main application areas include war room and meeting room, control center, arcade and the counter roadside booth.

At present, small spacing distance specification, with P1.6 and P1.2 are the most, so demand is the most standard specification for 0808LED 1010LED. Benefit from market demand, 2015-2016 manufacturers to actively carry out small spacing display.

LEDinside forecast 2015-2020 small screen display mainstream trends from 2015 Pitch2.5mm to Pitch0.8mm in 2020.

Backlight LED will benefit from a new pattern of quantum dots and CSP

The import quantum dot technology can also play in the CSP package, the future have the opportunity in the mobile phone backlight applications for LED backlight, notebook computer, tablet computer to create color better, in this way, the LCD screen when the quantum dot technology LED backlight, the bright colors and plan quality, not only did not lose OLED, but also more exciting than the OLED panel, the cost will be relatively low.

Xie Mingxun also said that in 2016 LED market demand for CSP products by the industry's most attention. Crystal power in CSP (chip size package) has mastered the yield and reliability of the product, and has a good match with the terminal design.

Crystal power with customers to jointly solve the LCD TV using side LED backlight design with CSPLED, is expected to further expand the overall demand for CSP.
