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.
