According to TrendForce's Optoelectronics Research Office, major TV brand manufacturers have introduced Mini LED backlight TVs. As technology improves and costs continue to optimize, it is estimated that Mini LED backlight TVs will reach 4.4 million units in 2021, accounting for about 2% of the overall TV market. . As Apple is about to launch Mini LED backlight products for IT products, South Korean manufacturers Samsung Electronics and LG both plan to launch Mini LED backlight TVs in 2021. Samsung Electronics in particular is looking at the market’s popularity and actively deploying the technology for TV applications , The shipment target next year is expected to reach more than two million units.
At present, the major TV brand manufacturers are focusing on the layout of high-end TVs. They mainly use 4K or OLED as the two main axes. Samsung will use the existing QLED wide color gamut with Mini LED backlight that can be adjusted in multiple zones. Improving the contrast and display effects to make the picture quality more detailed, coupled with the advantage of lower prices than OLED TVs, is expected to expand the market share.
TrendForce said that in 2021, Samsung will launch 55-inch, 65-inch, 75-inch, 85-inch and other large-size Mini LED backlight TVs, with 4K high-resolution picture quality, and adopt Mini LED multi-zone backlight control, which can change the existing The display contrast ratio has been increased from 10,000:1 to 1,000,000:1. It is estimated that the number of backlight partitions of Mini LED needs to be at least 100 zones or more to have such a high contrast effect; therefore, the number of corresponding backlight modules is also relatively increased. According to different design specifications of each TV, the number of Mini LEDs used is about Between 8,000 and 30,000, with the combination of high-resolution panels and multi-zone light control, consumers can upgrade their display experience.
Samsung Mini LED-backlit TVs are expected to use high-voltage LED chips as the backlight source, highlighting high dynamic contrast (HDR) and wide color gamut (WCG) to multiply the display effect, and a large number of and rapid rigorous testing and testing of LED chip wavelengths and specifications Sorting, including Sanan, Jingdian and Longda, Whitby, Shuttle, Trident, Macroblock and other related manufacturers have actively entered the supply chain.
TrendForce believes that although the overall decision has not been finalized and most manufacturers are still in the sample delivery stage, it is expected that the LED supply chain will once again set off a boom.
