According to reports, WitsView, a subsidiary of Jibang Technology, pointed out that although the iPhone X sales situation is not as expected, Samsung's production of organic diode (O LED) panels has been repaired, but the trend of OLED panels driven by Apple has taken shape.
WitsView estimates that the penetration rate of smartphones using OLED panels will reach 46% in 2021. The advantages of OLEDs in terms of technology maturity and production costs will make it difficult for Mini LEDs to play a role in the smartphone market in the short term.
AUO maintains the view of the previous corporate briefing. Although the world famous brand mobile phones adopt OLED panels, which drives the market to rise rapidly, the latest high-end smartphones are not sold because of the OLED panels. The OLED panels are not Wanling. Dan.
AUO believes that the micro-LED (MicroLED) panel will be an opportunity for the Taiwan panel industry. AUO has invested a lot of resources. In addition, the mini-light diode (MiniLED) applied to the panel backlight also has many opportunities to improve the panel. Specifications, cost performance.
WitsView pointed out that in addition to the supply of Apple's iPhone, Samsung's OLED panel also needs to supply its own brand of high-end smartphones, but other panel makers' OLED production yields are low, so each mobile phone manufacturer is also trying to find alternatives for its flagship model. Technology.
Although the Mini LED has high color saturation and high contrast comparable to OLED in terms of specifications, and can support high dynamic stability range (HDR) function, it has once become a product considered by the industry.
However, in addition to high color saturation, high contrast and fast response time, the biggest advantage of OLED is its self-illumination and bendability, which makes mobile phone manufacturers more flexible in terms of thickness and shape design.
WitsView shows that the Mini LED shrinks the LED chip size to 100 to 300 microns under the premise of the original liquid crystal display (LCD) structure, and the LED is placed in the backlight module through the matrix arrangement method. Take the 5.5-inch Full HD (FHD) screen as an example, the number of LEDs used can vary from 2,000 to 10,000.
When the number of LEDs is small, a long optical distance is required, which increases the thickness of the whole machine; although the number of LEDs is large, the optical distance required for the backlight can be shortened and the uniformity is better, but the heat dissipation problem is derived and the cost is greatly increased. How to achieve balance is the bottleneck that manufacturers still have to overcome.
