Title:
OLED SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2020/237750
Kind Code:
A1
Abstract:
The present invention provides an OLED substrate. The OLED substrate comprises: a plurality of pixel regions distributed at intervals. Each pixel region comprises an active region and a non-active region surrounding the active region. The active region comprises: a base substrate, a TFT layer provided on the base substrate, a flat layer provided on the TFT layer, and an anode provided on the flat layer. The anode is in contact with the TFT layer by means of an anode connection hole running through the flat layer. The non-active region is provided with a light sensor placement region spaced apart from the anode connection hole. The area of the light sensor placement region can be increased. When the OLED substrate is applied to an electronic device having a camera module, a light sensor of the camera module is placed in the light sensor placement region, so that the light receiving area of the light sensor can be increased, thereby improving the photography quality of the camera module.
