>> iPhone X Sales Not as Expected: Driving OLED Trends 8th, May,2018
WitsView, a maker of micro-network news, said that although the sales of the iPhone X are not as expected, Samsung, which produces organic diode (O LED) panels, has been under capacity utilization. However, the OLED panel driven by Apple has taken shape.
WitsView estimates that the penetration rate of smart phones using OLED panels will reach 46% in 2021. The advantages of OLEDs in terms of technology maturity and production costs will make it very difficult for Mini LED to have a space in the smart phone market in the short term.
AU Optronics maintains the view of the previous legal person's briefing. Although the world-renowned branded mobile phones use OLED panels to drive the market to climb rapidly, the latest high-end smart phones have not been sold for OLED panels. OLED panels are not in fact all-purpose. Dan.
AUO believes that the MicroLED panel will be an opportunity for the panel industry in Taiwan, and AUO has invested a lot of resources; in addition, MiniLEDs used in panel backlights also have many opportunities to increase the number of panels. Specifications, price/performance ratio.
WitsView pointed out that in addition to the Samsung OLED panel supply Apple iPhone, it is necessary to supply its own brand of high-end smart phones, but other panel makers OLED production yield rate is low, so mobile phone manufacturers are also trying to find alternatives for their flagship models Technology.
Although the Mini LED has high color saturation and high contrast comparable to that of OLED in terms of specifications, it can also support high dynamic stability (HDR) function, and it has become a product considered by the industry.
However, in addition to high color saturation, high contrast, and fast response time, OLEDs have the biggest advantage in their self-luminous and bendable properties, allowing handset manufacturers to be more flexible in either thickness or shape design.
WitsView shows that the Mini LED miniaturizes the LED chip size to 100 to 300 microns under the premise that the original liquid crystal display (LCD) structure does not change, and the LED is covered in the backlight module through the matrix arrangement method. Take a 5.5-inch Full HD (FHD) screen as an example, the number of LEDs used is as high as 2,000 to 10,000.
When the number of LEDs is small, a long optical distance will be required, resulting in an increase in the thickness of the complete machine; although a large number of LEDs can shorten the optical distance required by the backlight and have better uniformity, it will lead to heat dissipation problems and increase the cost greatly. How to achieve balance is the bottleneck that current manufacturers still have to overcome.
