OLED Smartphone Launch Products Slows Down In The First Half of 2022

/in , /by

The number of OLED smartphone launches, which had steadily increased from 2019 to 2021 reached only 110 units in the first half of 2022. 137 units had been released in 2019, 166 units in 2020, and 225 units in 2021. If this industry trend continues in 2022, OLED smartphones expected release will only be similar to 2021 or even slightly fewer than it had been last year.
Most of the smartphones released in the first half of 2022 were made in China. 98 products from China accounted for 89% of market share, followed by 9 products from Korea, 2 from Japan, and 1 from India.
By size, 6.6-inch products were the most with 34 types, followed by 6.4-inch products with 31 types and 6.7-inch products with 21 types. The largest sized product was Vivo’s ‘X Fold’, which was an 8.03-inch foldable. Not including the foldables, Vivo’s ‘X Note’ was the largest at 7.0 inches. The smallest product was Sony’s ‘Xperia 10 IV’, which was 6.0 inches.
By design, 102 types of punch hole models were released, with 4 narrow bezel types, 2 notch types, and 2 UPC types. There were two types of smartphones with UPC (Under Panel Camera) applied: ZTE’s Axon 40 Ultra and Nubia Red Magic 7 Pro.

By resolution, 51 products with 300ppi range, 50 products with 400ppi range, and 9 products with 500ppi or higher were released. No products under 300ppi were released. The product with the highest resolution was Sony’s ‘Xpeia 1 IV’, which had a resolution of 643ppi.
There were three foldable phones released in the first half of the year: Vivo’s ‘X Fold’, Honor’s ‘Magic V’, and Huawei’s ‘Mate Xs2’. All three types of foldable phones have a punch-hole design. The resolution of ‘Mate Xs2’ was 424ppi, which is 10ppi higher than the average OLED smartphones released in the first half of the year. Whereas ‘X Fold’ and ‘Magic V’ were two products with the lowest resolution among OLED smartphones released in the first half of the year.

 

[UBI Research China Trend Report] Will BOE Provide UPC Panel with Transparent PI Substrate to Oppo?

/in , /by

BOE, the largest display maker in China, produces UPC (Under Panel Camera) panels with transparent PI substrates.

UPC is a technology that makes a full screen of a smartphone possible by placing the front camera under the screen. The UPC technology that is currently commercialized is a method of patterning the cathode electrode and changing the resolution near the camera. However, this time it is expected that a transparent PI substrate will be additionally applied to the UPC panel supplied by BOE to Oppo.

Existing transparent PI substrates had difficulties in mass production due to the high process temperature of LTPS TFT. Yet, the recent test results of the panels with the transparent PI substrate produced by BOE reached most conditions of satisfactory levels even at the LTPS TFT process temperature.

The UPC OLED panel with the transparent PI substrate developed by BOE is expected to be installed in Oppo’s upcoming products.

Samsung Electronics widens the technology gap by applying new technology to ‘Galaxy Z Fold3’.

According to the ‘2021 OLED Components and Materials Report’ recently published by UBI Research, the ‘Galaxy Z Fold3’, which is expected to be released by Samsung Electronics in August, has UPC (under panel camera) and pol-less (or color filter on) encapsulation, COE) and S Pen technology are expected to be newly applied.

First, UPC, a technology that realizes the full screen of a smartphone by placing the front camera under the screen, has been mentioned using a transparent PI substrate and various technologies such as laser patterning, but in the end, the cathode electrode is patterned with a laser and the resolution near the camera is different. Thus, it seems that the maximum transmittance was secured. It is analyzed that the transparent PI substrate was not applied to the mass production process due to the high process temperature of the TFT.

Although many panel makers have developed pol-less technology, which replaces polarizers with color filters and low-reflection technologies, they could not be applied because they did not show as much anti-reflection effect as polarizers. The polarizing plate is effective in preventing external light reflection, but reduces the amount of light emitted from the OLED light emitting layer by more than 50%. If the polarizer is removed, more light can be emitted with the same power to the outside, so if the same luminance is implemented, battery consumption can be reduced. Samsung Display seems to have implemented pol-less technology by applying color filters, low-reflection films, and black pixel define layer (PDL).

The S Pen is finally applied with an electro-magnetic resonance (EMR) method, and the 30 um thick product used in the previous work is expected to be used as it is for the UTG. The AES method, which does not require a digitizer, was also considered due to the flexibility issue of the digitizer made of metal, but it is expected that the S Pen will eventually be applied in such a way that the digitizer is located on both sides of the panel.

The ‘2021 OLED Components and Materials Report’ published this time includes not only the development trend of foldable OLED, but also the development trend of mobile devices and materials for TV. It is expected to be of great help to related companies.
