In recent years, the global LED application market has shown a growing trend, mainly driven by the explosive growth of the lighting market. The trend of domestic application market is also consistent with the global, and the demand for chips has increased significantly. Among them, the backlight market has been experiencing rapid growth in industrial transfer, and the lighting market has become the main growth force since 2013. At present, the localization rate of China's LED industry chips has reached 80. With the continuous growth of market demand, should enterprises focus on product research and development? As far as the LED display market is concerned, the total sales volume has increased year by year, and the growth rate has slowed down. The indoor display screen has been developed to high density, and the outdoor display screen has been developed with wide viewing angle and high image quality, and the dot pitch has been continuously reduced. Among them, the application of small-pitch LED display has developed rapidly, driving the demand for LED chips to increase rapidly. Specific to the development of technology, high-density indoor display applications are characterized by high density, high scanning, high refresh, high gray scale, so the direction of chip optimization is small size, high light efficiency, consistent under low current drive Good, at the same time, the chip has high reliability, and it has good anti-back pressure, anti-ESD and anti-overshoot current capability. The surface-applied outdoor display application features large display angle and good picture quality. Therefore, the optimized direction of the chip is higher brightness, good light consistency, and better weather resistance of the chip. Look at the backlight market again. The decline in demand for TV backlight chips is mainly due to the direct penetration and LED light efficiency improvement, and the subsequent major growth drivers will come from the tablet market. The comprehensive strength of China's chip companies and packaging companies continues to increase, and the backlight industry is shifting significantly to mainland China. On the technical level, the chip optimization direction of high-brightness and small-size backlight is to continuously optimize the axial light intensity, improve the light efficiency, and make it smaller, thinner and brighter; high-brightness, high-reliability large-size TV backlight chip The optimized direction is to match the thinner light guide plate, improve light efficiency, save cost, and match the phosphor to achieve a wider color gamut. Finally, look at the lighting market. Alternative lighting is a cost-effective market. With the sharp decline in the price of LED lighting terminal lamps, the market replacement rate of LED lighting will increase rapidly in the future. Estimated by sales, it is estimated that it will reach the total sales of the lighting market by 58 in 2016 and 78 in 2020. At the same time, the global OEM of LED lighting products is also concentrated in mainland China. In 2013, the proportion of LEDs in China's lighting products exports has reached 57. In terms of chips, the domestic market demand for cost-effective whole-light reduction solutions, while foreign markets prefer high-efficiency solutions. The optimization direction of the chip is centered on improving the light efficiency lm/W, increasing the brightness and reducing the size, improving the light-effect price ratio of the product, developing high-voltage chips and flip-chip technology.
