Abstract

The invention provides a display panel, a display device and a manufacturing method thereof; the display panel comprises a display area, and the display area comprises: a light-emitting subarea and anexternal light transmission sub-area; an anode arranged in the light emitting subarea; a light-emitting layer arranged on the anode and is positioned in the light-emitting subarea; a cathode arrangedon one side, far away from the anode, of the light-emitting layer and covers the display area; a covering layer arranged on one side, far away from the light-emitting layer, of the cathode; the covering layer at least covers the light-emitting subarea; by patterning the covering layer, the thickness of the original covering layer on the cathode is kept, the normal electrical performance of each film layer and the display effect of the display panel and the display device are ensured, and meanwhile, the penetration capacity of light rays of the external light transmission sub-area is enhanced,so that the transparent display effect of the display panel and the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method thereof. Background technique [0002] Due to the high penetrability of the screen, the transparent display device can transmit the external light in front of the screen to realize the camera technology under the screen. On the other hand, it can transmit the external light behind the screen so that the user can see the objects behind the screen. An organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device is an ideal transparent display device because it does not require a backlight source. The mainstream top-emitting OLED devices must use a "semi-transparent and semi-reflective" cathode layer in order to improve the light extraction rate and color purity. However, since the cathode is vapor-deposited on the entire surface of an open mask (OPM), the penetrating ability of the screen is ...
