Abstract

The embodiment of the invention discloses a rollable display panel and a rollable display device. The rollable display panel comprises a flexible substrate, a driving array layer, a light-emitting device layer and a pressure-sensitive functional layer, and the driving array layer is located on one side of the flexible substrate; the light-emitting device layer is located on one side, far away fromthe flexible substrate, of the driving array layer; the pressure-sensitive functional layer is located between the flexible substrate and the light-emitting device layer, the pressure-sensitive functional layer extends from the first side to the second side of the display panel, the first side and the second side of the display panel are arranged in the curling direction of the display panel, andthe pressure-sensitive functional layer comprises at least one of a resistance-type pressure-sensitive functional layer and a capacitance-type pressure-sensitive functional layer. And the resistancevalue and / or the capacitance value of the pressure-sensitive functional layer are / is changed along with the curling length of the display panel. According to the technical scheme of the embodiment ofthe invention, the detection of the unfolding length of the rollable display panel can be realized, and the thickness and size of the display device can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a rollable display panel and a rollable display device. Background technique [0002] In order to meet the needs of users with a large screen, a large field of view and easy portability, a rollable display device has emerged as the times require. The rollable display device generally includes a flexible screen, and the smaller the radius of the flexible screen when it is rolled, the smaller the volume of the rollable display device, and the more convenient it is to carry. By folding the flexible display panel or rolling it on a roll to reduce the overall size of the flexible display device, it can be carried; the flexible display has attracted wide attention. [0003] During the unfolding and winding process of the flexible display panel, the user may not fully unfold it, and the area of ​​the area where the image is displayed will change; at present, the area of ​...
