CSP LED four most concerned about the application trend, the logic of how you see?

Finally sold! Recently, Royal PHILPS announced that the company signed an equity transfer agreement, the LumiLEDs80.1% stake sold to Apollo (Appollo) some of the global fund management company of Affiliated Companies management, PHILPS Lumileds will retain the remaining 19.9% stake. The Lumileds for this sale, means that CSP LED technology have changed hands? As a senior CSP LED technology tracking crazy today do not talk about other talk about CSP. Looking back in the past, CSP was launched by Lumileds for nearly ten years, has been the foreign giants to seize the initiative, and now domestic companies have taken off. Today, about LEDinside to achieve domestic production of large enterprises, general manager of Zheng Haibin, deputy general manager of energy to talk about CSP, in addition to being pushed out of the flash market, the future trend of several major markets.

A, breaking the straight down type "thick" pain points, CSP high-end market penetration pulled

The backlight device trend

In panel factory or TV brand manufacturers continue to reduce the cost of the trend, direct type backlight TV technology because it can reduce the use of LED the number of pieces, so that the backlight costs can be further decreased, the proportion of the TV market share gradually increased. However, straight down backlight TV because of the thick impact of beauty, has been a pain point. However, with the introduction of CSP, these pain points are gradually resolved, and the power of the CSP can be done more, not only to the direct down type of the cost of the backlight model to further reduce, but also can do thinner. According to Zheng Haibin, deputy general manager of the domestic CSP production enterprises in Shenzhen, general manager of energy consumption to LEDinside, said the current energy saving CSP has been used in the field of large-scale backlight, and is increasing the layout of the lighting field. Zheng Haibin also revealed that the current CSP LED is still used in high-end brands, because the price is still relatively high, but the main reason is that the cost of the chip. At present, the yield of the chip is not very high, which is the main reason for the high cost. For packaging companies, the price of the product is limited to the chip side and can not compete with the current price of LED products, but for the high-end backlight market, but it has a congenital advantage. Compared to the previous backlight module, direct type with side entering type cannot be comparable to light, but the arrival of CSP is to break the existing balance, so that high quality and inexpensive as possible, this is also the reason why the current CSP in the field of backlight off.

Two, the lighting market has just started, the future force in the light engine and intelligent lighting

The CSP LED lighting circuit

Because of the small size of CSP, increase the flexibility of the lamp design, is considered to be the development trend of LED lighting miniaturization and highlight. However, the application of CSP in the lighting is different from the backlight, lighting backlight module relative to the cost of the entire application side is completely different. Zheng Haibin said, CSP relative to the cost of the entire TV is the difference between tens of thousands and thousands of blocks. But to the lighting applications, is a few pieces with a few pieces of the problem, the order of magnitude changed. So CSP lighting applications, not simply to provide CSP chip on it, more is integrated into the module to help the application side to do some of their work to improve the added value of CSP. But why can't the CSP lighting of the packaging enterprises go LED? The first is the size of CSP is too small for SMD technology is not easy to do lighting manufacturers can work; secondly, to do a good job, investment than before to invest into the machine, of course, for these companies, as the Buddha really is not too big, but there is a big investment risk but for small and medium sized lighting enterprises; third, while for the packaging plant, because the CSP SMT operation, need precise positioning of special package solid crystal machine, or application of factory SMT equipment is not up to the chip level SMT accuracy. In addition, there is another point is that if the package of the enterprise model and even after the light engine are done, then the lighting application will evolve into a light asset lighting design companies and OEM companies. The lighting design in addition to its own lighting design and extension of a single product lighting design, such as smart lighting, smart home, such as the edge of the lighting design company.

Three, small spacing hot market questioned technical surplus, but Micro LED has come to

Compared to backlighting, no one is currently seeing CSP on the display, but it can be seen that there is no exception to the COB display is a lot of. Recently, a veteran of the display company LEDinside said that the current COB display has a lot of cases, and good response. According to reports, the COB display is the LED package on the PCB board, because the heat is directly through the PCB board cooling, heat easily distributed, almost no serious optical attenuation, so few dead lights, greatly prolong the life of the screen. While the traditional surface mount LED product chip is fixed on the bowl, not in direct contact with PCB, mainly through the colloid and four pads of heat, the heat radiating area is small, the heat would be more concentrated on the chip, long time will cause serious optical attenuation phenomenon, even death light phenomenon, reduce the service life and the quality of display screen the. But now the COB display screen are used in the LED structure of the dress, if the import of flip chip or CSP, it will not only provided higher heat dissipation, higher reliability, but why not, obviously still cost. CSP can cut into the display? In fact, from the LEDinside visit trillion energy saving Zheng Haibin
