In the past year, ultra-high-definition, large-size, intelligent, curved and other elements have become the hotspots in the TV industry, and various new technologies are emerging. The world's major TV manufacturers have launched products with the above elements without exception. Seize the market. As a manufacturer of core chips and light source products in the middle and upper reaches of the LED industry chain, Jingke Electronics (Guangzhou) Co., Ltd. has also introduced high-power, high-brightness LED backlights with the latest LED chips and packaging technologies, providing over 95% of high-color The domain experience is almost close to quantum dot technology and has very high stability. Recently, during the 2015 China Electronic Information Expo, this reporter interviewed Dr. Xiao Guowei, President of Jingke Electronics (Guangzhou) Co., Ltd. (hereinafter referred to as Jingke Electronics), and asked him to introduce in detail the latest high-brightness LED backlight technology of Jingke Electronics. And related solutions.
Dr. Xiao Guowei introduced that as a component supplier of LCD TVs, Jingke Electronics mainly provides high-power high-brightness LED backlights. The reason why LCD TVs can achieve ultra-high color gamut is mainly the innovation and performance improvement of TV backlight technology. For display-based backlights, Jinko Electronics provides high-brightness LED backlights with the latest LED packaging technology and LED phosphors, and achieves a high color gamut of over 95% with proper LCD ratio, while traditional LCD TV gamuts Only 70% -75%.
Talking about quantum dot technology, Dr. Xiao Guowei introduced that although quantum dot technology can make the color gamut of liquid crystal TV reach 110%, due to the inherent deficiency of the quantum dot itself, it has a relatively large attenuation to high temperature and damp heat. At present, Jingke Electronics is focusing on the protection of quantum dots by directly encapsulating quantum dot materials on the backlight of LEDs, which not only further reduces the cost, but also can reduce the thickness of the TV set.
With the emergence of large-size LCD TVs with ultra-high color gamut, ultra-high resolution of 4K and above, and quantum dots, Jingke Electronics has begun to focus on high-resolution LED backlight technology and product development above 4K. Dr. Xiao Guowei introduced that Jingke Electronics mainly enhances the high color gamut performance of LED backlights through the latest R powder packaging and COB packaging technology.
In response to the requirements of high reliability and high stability of backlight devices, Jingke electronic packaging devices rely on flip-chip gold-free technology to develop high-stability LED backlight products with high brightness, high light efficiency and low heat. Resistance, ultra-thin package, small size and good color consistency. At present, the company has introduced high-reliability side-emitting backlight package devices 4014, 7020, direct-lit backlight devices 3030, 2835, and gradually won market recognition. Dr. Xiao Guowei said, “Because LED flip-chip backlights have the advantages of high power and packaging, they are increasingly used in TV backlights.â€
"Although the proportion of LED devices and packages in the entire TV set is very low, but one lamp is dead, the entire TV is scrapped. From the characteristics of the material itself, there is definitely a product quality risk above 2W. Jingke Electronics recently In the development of some new materials such as SMC, can withstand higher temperatures. Compared with consumers' high requirements for TV performance, I believe that the quality of LED backlights is far more important than the cost reduction of LED backlight systems. In the future, Jingke Electronics is committed to providing LED backlight products with high color gamut, high brightness and high reliability," he said.
For the future development of LED backlights, Dr. Xiao Guowei believes that the change of LED chip structure and the introduction of quantum dot technology will provide a better choice for TV backlights. The performance of LED backlights in high brightness and high color gamut will be the trend and direction of development in the next 1-2 years.
Color flash solutions to restore the true color shot <br> <br> addition to the LED technology development of high-brightness backlight, Crystal Electronics also for the rapidly growing market of mobile devices, has developed a two-color high-brightness high-power flash. Jingke Electronic's two-color solution is a true color flash solution, which can match warm colors with cool colors, truly restore the color difference of shooting, and improve white balance.
As a very important part of the camera, the flash plays the most important role in restoring the color of the photo. As mobile phone pixels continue to climb, users have new requirements for flash. Dr. Xiao Guowei introduced that this product uses Jingke Electronics' industry-leading LED flip-chip technology, mainly concentrated between 1.5W-3W, suitable for smart phone configuration above 1200 pixels, and it is also the first two-color flash product in China. Jingke Electronics' new EFG model can meet the requirements of 16 million pixel camera, and the 1m center illumination is 180lx.
In order to meet the needs of true color photography, Jingke Electronics supplements the warm color with LED flash to perform color reproduction. “The currently used warm-tone flash is lacking in red, and Jingke Electronics uses a warm-toned flash to complement the red-tone color, which allows the RGB three-color reduction capability to meet satisfactory requirements. Full-spectrum LED common market The display technology has a CRI of 70, and Jingke Electronics' full-spectrum LED solution can exceed 90%.†Dr. Xiao Guowei introduced, “Jingke Electronics Full Spectrum LED can restore the full-band color difference and enhance the color of photos.â€
Dr. Xiao Guowei said that only Apple smartphones use two-color flash. He also said, "One of the biggest problems with high power wattage is optical consistency, and the two-color flash has placed higher demands on packaging and materials. Samples of Jingke Electronics have been provided to our customers."
Equity investments, strategic alliances build an international industrial chain <br> <br> current LED applications mainly in the two largest display backlighting and illumination in these two fields. Jingke Electronics has been involved in these two fields. With the continuous development of LED technology, CSP packaging and flip-chip technology can be well combined, which can eliminate the need for the conventional package to bond the wire on the bracket, so that the size of the product is basically close to the size of the LED chip. At the same time provide better heat dissipation performance. At present, Jingke Electronics has been able to complete the packaging of such LED backlight products and apply it to TV backlights together with TV manufacturers.
"The use of such backlights can make the thickness of the direct-lit backlight close to the thickness of the side-lit backlight, and the cost is further reduced. At the same time, the wattage of the direct-lit backlight can be increased from 2W to 3W, which makes the TV The backlight technology has taken a new step." Dr. Xiao Guowei said, "Especially for large-size, high-definition LCD monitors, this technology can meet the backlight requirements of 4K or even 8K LCD panels. Therefore, in the field of white light chips. Jingke Electronics is the first company to introduce such a solution. Its main technical details are based on flip-chip LED chips and packaging technology, which is difficult for traditional LED packaging companies to achieve."
For the "no package" and "no power" LED technology solutions, Dr. Xiao Guowei said that strictly speaking, "no package" is not without packaging, it is only a combination of the traditional LED chip and packaging process, completed in the chip link Part of the chip packaging process, or the combination of chip and packaging process, compresses the entire process and steps. Of course this requires a higher process and equipment. To be precise, the so-called no-package technology is chip-level packaging technology. At the same time, the current development direction of the LED industry is to reduce costs and improve light efficiency. From the current point of view, due to the sharp decline in the cost of LED devices and packaging in the entire lighting field, the relative proportion of power control drive and heat dissipation costs has increased. The so-called power-free technology proposed by the industry is still based on traditional standard LED devices, which can provide a high-voltage LED, making the LED power supply driving circuit more simple. The “no power†LED technology solution provides convenient conditions for downstream terminal manufacturers, mainly for low-end and mid-range lighting.
In addition, for LED standard optical components (called LED light engine in Taiwan), he introduced that Jingke Electronics and many international companies have launched a series of LED light engines or standard optical components, but there are still some problems in the whole industry. Mainly because LED has not yet formed a unified lighting industry standard. Despite this, he still believes that LED standard optical components are the possible future direction.
All along, Jingke Electronics has achieved a technologically advanced and innovative position through continuous research and development and innovation. According to reports, Jingke Electronics has obtained or applied for more than 100 patents, including related patents in Europe and the United States, mainly for flip-chip and high-power LED chip technology and chip-level light source technology patents. At the same time, Jinko Electronics has also established strategic alliances with strategic partners to cope with international competition. In addition, Jingke Electronics is making a large amount of investment every year, and through the equity investment and strategic alliance, has built an international supply chain to protect the service quality of downstream customers and enhance the competitiveness of downstream products. At present, Jingke Electronics has established a competitive upstream supply system for Taiwanese companies and European and American companies to improve the supply chain system for TV manufacturers such as TCL, Skyworth, Changhong and other international manufacturers including lighting such as Philips Lighting. Chain service.
For the future development of the company, Dr. Xiao Guowei said that Jingke Electronics will base itself on mainland China to further explore overseas markets and provide better LED application solutions for overseas customers of LED backlight and LED lighting. At the same time, Jingke Electronics will cooperate with downstream customers to increase the research and development of LED intelligent application devices and platforms.
