[Text / high-tech LED Xu Chaopeng] Xiaomi president Lei Jun said, "As long as you stand in the wind, pigs can fly." And CSP this magical gadget has been on the air of public opinion since its birth, and guides the current LED The lighting industry has undergone a major transformation.
Recently, Zhou Xuejun, Marketing Director of Lumileds Asia and Xie Mingxun, Deputy General Manager of Jingyuan Optoelectronics R&D Center, pointed out that CSP will be applied to LED TV backlight in 2016. At the same time, according to a number of well-known personalities, CSP is the first to be applied in the field of backlight and high power next year, and it has great possibilities.
“Since this year, the need for manufacturers to reduce costs has become imminent, so the role of CSP LEDs in the LED industry is becoming more and more important. It can be said that it has become the wisdom of the majority of LED manufacturers to reduce manufacturing costs. Small but with the same luminous flux, and the chip requires less raw materials. According to Zhou Xuejun, CSP LED can reduce the cost by nearly 40% compared with traditional LED.
It is reported that due to the high optical density and high light intensity of CSP light source, the current CSP products have been widely used in large-angle light source products, such as television, mobile phone backlight, etc., but the most worth mentioning is the TV backlight field, because In the current TV application, the brightness of the traditional medium power device can not meet the requirements of 4K TV.
“Therefore, according to the current situation, CSP has become the development focus of the 2015 direct-lit backlight design, and its biggest advantage lies in cost saving.†Xie Mingxun mentioned that Jingyuan Optoelectronics’ CSP products have been used in the backlight field for a long time. Very mature product.
According to the wafer, compared to the traditional package structure, the CSP size is reduced by about 34%, and the cost can be reduced by 20%. Although the CSP has a high single cost, the 5-sided illumination can be omitted in the field of direct-lit backlights. The secondary optics problem, and the number of particles can be reduced, the distance is reduced, thus making the fuselage thinner, and the overall accounting cost can be reduced by 1/3.
According to the recent LED backlight data research conducted by the High-tech Research Institute LED Research Institute (GGII), the direct-type backlight penetration rate has been greatly improved without any surprise, from 57% in 2014 to 59.5% in 2015, and GGII also expects that This data will further increase to 68.5% in 2019, so CSP will have more room for development in the field of backlighting.
"In the original 2835 or 5630 device, it was the Korean TV backlight that simplified it to the extreme. At this time, mass production, and finally this technology penetrated and occupied the lighting market, and it is expected that CSP will have the possibility to go the same way. According to industry insiders, the proportion of new TV-type CSP backlights next year will probably reach 50%.
Moreover, many LED experts have agreed that after CSPLED is applied to TV backlights, it will be applied to lighting fixtures in the future, but the time points predicted by experts are different. For example, Zhou Xuejun estimates that CSPLED will be in 2016. The year began to be applied to lighting fixtures, and Xie Mingxun argued that the application of CSPLEDs in lighting fixtures should start in 2017.
“Recently, there are industry rumors that LGDisplay and Samsung are very interested in replacing traditional LEDs with CSP LEDs as backlights for LCD TVs. CSPLEDs are more closely arranged, have higher brightness and use fewer LEDs in TV backlights. In the end, LGDisplay and Samsung decided to use CSPLED as the TV backlight, so the market penetration of CSPLED will be greatly improved." Zhou Xuejun finally mentioned.
