Company News >> 2021 smartphone OLED panel penetration rate will reach 46% 13th,Apr,2018
                                           It is reported that because of the sales volume of iPhone X is lower than market expectations, Samsung has reduced the utilization rate of OLED production lines. The tension in the supply of OLED panels over the past two years has also eased. According to Trendsce's WitsView data, Optoelectronics Division, Apple has begun to drive the development of OLED panels. It is expected that the penetration rate of smart phone OLED panels will reach 46% in 2021. Due to the impact of OLED technology maturity and competitive costs, Mini LED may not be able to gain growth momentum in the smart phone market in the short term.
WitsView pointed out that the current supply of Samsung OLED panels has been occupied by the iPhone and high-end Samsung smartphones, while the yield of other OLED panel makers is still low. Therefore, mobile phone manufacturers have been trying to find alternatives for various flagship models. The Mini LED is considered a viable option because it is comparable to OLED in terms of high color saturation, high contrast, and support for HDR.
However, the advantages of OLEDs are even more pronounced. In addition to high color saturation, high contrast, and fast response, the biggest advantage of OLED panels is their self-luminous and bendable characteristics, which makes mobile phone manufacturers more flexible in the thickness and design of mobile phones. The Mini LED can be used as a transitional product before the Micro LED is fully ready for mass production. With the original LCD structure unchanged, the size of the LED chip will be reduced to 100 to 300 microns, and the LEDs can also be placed in the backlight module by the matrix sorting method. For example, in a 5.5-inch FHD display, the number of LEDs used is as high as 2000 to 10,000. A smaller number of LEDs requires a longer optical distance, which will make the device have a greater thickness. Although a large number of LEDs can reduce the required optical distance and improve uniformity, making the entire device thinner, it can lead to heat dissipation problems and make the cost higher. At present, how to achieve this balance is still a major bottleneck for manufacturers.
From a cost perspective, OLEDs are more competitive at this stage. Taking a 5.5-inch hard OLED panel as an example, the cost is about 17 to 18 dollars; however, for a Mini LED backlight board of the same size and the same resolution, the cost may be doubled to 35 to 40 US dollars. With the release of OLED supply tight news, WitsView said that in the long run, OLED smart phone panels offer relatively weak, and the drop in LTPS panel prices will also bring more pressure to Mini LED. Therefore, if the Mini LED cannot reduce its cost, it will be difficult to compete with the OLED panel in the high-end smartphone market.
The cost of using a Mini LED in smartphone backlighting depends on the number of LED chips used and the wafer transfer efficiency. Therefore, many LED manufacturers try to reduce costs through different technical solutions, such as reducing the number of LED chips by optical adjustment, or increasing the transmission efficiency of chip bonding machines to reduce the cost of bonding.
However, in niche markets with higher total profits, costs are not a priority for suppliers. Therefore, Mini LED will have more opportunities in the niche market.
