FIELD OF INVENTION

The present disclosure relates to a field of display technology, and more particularly to an organic light-emitting diode (OLED) display panel and a display device.

BACKGROUND

Mobile phones with full screen design have extremely high viewing area-to-screen ratios and give users excellent user experience, and thus have become one of the most popular techniques.

With development of full screen designs, there is a trend that electronic devices, such as a camera, are disposed under display screens. According to prior art, to ensure that electronic devices, such as a camera, disposed under display screens can receive enough light, layers including thin film transistor (TFT) circuits, light-emitting layers, cathode structures, etc. for displaying images and positioned above the camera are removed. That is, a hole formation technique is required to achieve such an objective. However, for such a hole formation technique, because the layers for displaying images in the hole formation region have been removed, the hole formation region cannot display images. This is not really a full screen design.
