Mini LED backlight technology is regarded as a high-end advanced version of LCD. It has the advantages of fine-district dynamic dimming, HDR high contrast, and high-brightness display effects. Compared with traditional OLED products, the picture effects are equally good, and Mini LED backlights have longer service life and wider application fields. They are expected to compete in the OLED market, so they have attracted much attention from the industry. With the release of Mini LED backlight products by many well-known companies, it has triggered a new round of category update boom in the market.
The commercial application of Mini LED backlight dates back to 2019, when Apple released a Mac display with a Mini LED backlight solution; in 2020, Lenovo released the first Mini LED backlight display; in April this year, Apple released the first Mini LED backlight tablet; in July, Huawei released its first Mini LED backlight TV; in October, Apple released its first Mini LED-backlit notebook computers... It can be seen from its history that its outbreak and advancement are extremely rapid. Apple, Lenovo, Huawei, TCL and other leading companies in the industry have entered the market, which also hints at the huge potential of Mini LED backlight and releases a signal for new technological reforms.
Mini LED backlights target users in the civilian display market who are highly price-sensitive. However, current Mini LED backlights are affected by factors such as uncertain technical routes and high cost of Mini LED chips, which affect product pricing and lead to insufficient consumer acceptance. How to break through the tight siege and accelerate market penetration must achieve a balance between cost and technical value, and the choice of LED packaging technology will be the key to breaking the situation.
POB vs COB
The mainstream routes for Mini LED backlight packaging technology are POB and COB. Both solutions have their own advantages. Overall, the POB solution has more advantages under current technology, breaking the constraints of high COB costs and helping to stabilize Mini LED backlight prices.
Industrial chain: The POB industrial chain is mature, and there is no need to replace or upgrade existing equipment. It can achieve large-scale mass production and has significant advantages in reducing production costs.
Raw materials: Compared with COB, when using the same PCB substrate, POB has low precision requirements, high yield, and low cost; chips can be produced using large-scale wafers, smaller size chips, and lower costs.
Technical process: 1. Production yield: Due to the large pad size and the use of mature processes, the yield of POB is significantly better than that of COB. Maintenance method: POB can be repaired manually to achieve low-cost maintenance. 2. Luminous efficiency: Due to the influence of chip size, the photoelectric conversion efficiency of POB is higher than that of COB, and the power consumption is saved by about 25%. In addition, the CHIP series large-angle packaging of the Mini backlight POB solution can realize ultra-thin designs in notebooks, e-sports, and monitors, and is highly competitive.
In the application of Mini LED backlight in different niche fields, the POB packaging route can simultaneously meet the needs of high contrast, low power consumption, high reliability, low cost, energy saving, etc., and has a competitive advantage whether in vehicles, e-sports, notebooks or large TVs.
Based on more than ten years of accumulation of LED packaging technology, Jingtai has professional R&D and manufacturing capabilities for Mini LED backlight POB solution packaging devices. The technical process and industrial chain support are very mature. It can now increase its large-scale mass production capacity to 6000KK, and its production capacity ranks among the top in the industry. For applications in different fields, Jingtai has launched three targeted backlight LED solutions:
Jingtai has launched the Hummingbird series POB solution. With the advantages of ultra-long life, high cost performance, mature technology, high reliability, ultra-large angle, etc., it has achieved an excellent balance in terms of cost and performance, making the price of Mini LED backlight products more competitive.
In the future, in all aspects of the Mini LED backlight industry chain, manufacturers are accelerating their layout and continuing to increase their investment, which is expected to create a huge market in the next few years. Jingtai's solution will help consolidate the Mini LED backlight technology route, drive down the overall cost trend, open up the acceptance of the civilian display consumer market, and accelerate the formation of new growth points.
