Problems solved by technology
[0002] In recent years, folding display panels have become more and more popular among consumers. When the cover layer of the folding display panel is shipped by the upstream product manufacturer, it is usually pre-bent once to ensure its bending performance. The cover layer determines its bending direction. However, when making a folding display panel, it is difficult to distinguish the front and back of the incoming cover layer (that is, the bending direction after lamination). The bending direction during the work is opposite to the bending direction during the pre-bending test, which will greatly reduce the bending performance of the cover layer

The embodiment of the invention discloses a folding display panel and a display device. The folding display panel comprises a panel body and a cover plate layer located on one side of the panel body, the cover plate layer comprises a first face attached to the panel body and a second face opposite to the first face, the first face corresponds to the first side of the folding display panel, and the second face corresponds to the second side of the folding display panel. In the front view direction of the first side, the front view pattern of the first surface is a first pattern, in the front view direction of the second side, the front view pattern of the second surface is a second pattern, and the first pattern is different from the second pattern; the upward view pattern of the first surface of the cover plate layer is different from the downward view pattern of the second surface of the cover plate layer, so that the front surface and the back surface of the cover plate layer are easier to distinguish according to different patterns when the cover plate layer is attached, the bending performance of the cover plate layer is prevented from being influenced by the reverse attachment of the front surface and the back surface, and the product quality of the folding display panel is ensured.
Description
technical field [0001] The invention relates to the field of display, in particular to a folding display panel and a display device. Background technique [0002] In recent years, foldable display panels have become more and more popular among consumers. When the cover layer of foldable display panels is shipped by upstream product manufacturers, it is usually pre-bent once to ensure its bending performance. The cover layer determines its bending direction. However, when making a folded display panel, it is difficult for the incoming cover layer to distinguish the front and back sides (that is, the bending direction after bonding). If the wrong front and back sides are attached, the cover layer The bending direction during the work is opposite to the bending direction during the pre-bending test, which will greatly reduce the bending performance of the cover layer. [0003] Therefore, there is an urgent need for a foldable display panel and a display device to solve the abo...
