Abstract
The present invention provides a flexible and foldable organic light-emitting diode (OLED) display device. When the flexible and foldable OLED display device is bent inward, information displayed on an organic light-emitting layer can be directly viewed through a substrate and a drive layer, without extending the flexible and foldable OLED display device, thereby improving usability of the flexible and foldable OLED display device. In addition, display areas at different positions and having different shapes are designed, so that the flexible and foldable OLED display device has more diversified appearances and functions.
Claims16
A flexible and foldable organic light-emitting diode (OLED) display device, comprising:
- a flexible substrate, a drive layer, and an organic light-emitting layer, wherein the drive layer is disposed on the flexible substrate, the organic light-emitting layer is disposed on the drive layer, the flexible substrate has a first transparent area, and the drive layer has a second transparent area, wherein an overlapping area is defined between an orthographic projection of the first transparent area and an orthographic projection of the second transparent area in a direction perpendicular to the organic light-emitting layer, the overlapping area on one side of the flexible substrate away from the organic light-emitting layer functions as a display area, and wherein the drive layer further comprises a non-transparent area, a ratio of an area of a drive circuit in the second transparent area to an area of the organic light-emitting layer is less than a ratio of an area of a drive circuit in the non-transparent area to the area of the organic light-emitting layer, one end of the non-transparent area is provided with a groove recessed toward a center of the non-transparent area, and the second transparent area is disposed in the groove.
