>> Mini LED backlight jump display market, battle OLED technology 10th,May,2019
After nearly three years of development, Mini LED backlight technology will formally compete with OLED in the field of display in 2019. Looking at the advantages of Mini LED backlight technology, Apple is also actively cooperating with suppliers in Taiwan and Japan, however, due to LED The increase in the number of uses will lead to increased costs, so how to reduce costs to reduce the price gap with traditional LCD panels will be the key to the future popularity of Mini LED backlights.
According to the latest "2019 Mini LED and HDR high-end display market report" by TrendForce LED Research (LEDinside), after nearly three years of development, Mini LED backlight technology will formally compete with OLED in the field of display in 2019, due to Mini LED backlight technology. The only difference from the traditional LED backlight technology is the use of more Mini LED chips. Therefore, for the panel manufacturer, it is only necessary to re-invest in some equipment, such as the transfer of parts, testing equipment, and redesigning the driver IC and selecting the substrate. In the case where the existing panel production line can be used, it is a painless upgrade for the panel factory.
TrendForce said that compared to the characteristics of the two, the Mini LED backlight display has multi-zone local dimming function, the contrast effect is similar to that of the OLED display, and in some product lines, the cost of the Mini LED backlight display is even lower than that of the OLED display. For the traditional LCD panel factory, it will be an opportunity to upgrade the product specifications and have the opportunity to compete with OLED technology.
However, compared with the traditional LCD panel, the increase in the number of LEDs will of course lead to increased costs. Therefore, how to reduce the cost to reduce the price gap with the traditional LCD panel will be the key to the future popularity of the Mini LED backlight.
Looking at the advantages of Mini LED backlight technology, Apple is also actively working with suppliers in Taiwan and Japan, with the goal of importing desktop displays, notebooks and tablets.
From the perspective of the supply chain, the Taiwan LED panel factory is the most active in the OLED panel production competition, so the Mini LED backlight technology solution is the most active. AUO and Innolux are jointly developed by their LED companies, such as AUO (2409) and Ronda (3698), and Innolux (3481) focuses on companies such as Rongchuang (3437) and Guangqi (4956). The partners hope to continue the competitiveness of the LCD panel products. In addition, Taiwan's LED manufacturer, Jingyuan Optoelectronics (2448), launches customized products for major customers, and also has the ability to modify the equipment by itself, mainly in high-order display. And backlight applications.
Chinese manufacturers are also actively developing Micro LED and Mini LED technology. For example, Sanan Optoelectronics established the first Micro LED epitaxial wafer and wafer production line in the first quarter of 2019, and has developed Micro LED products with a chip size of 20 microns. Sanan has formed an alliance with Samsung Electronics to become the preferred supplier of Mini LEDs for Samsung Electronics. The Chinese panel maker BOE announced that it has partnered with Rohinni to form a joint venture to produce Micro LED and Mini LED solutions for display backlights. The main goal is to improve the production speed, accuracy and yield of LEDs transferred to the substrate. More cost-competitive products.
