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.
