Problems solved by technology
[0003] Existing foldable display devices generally include a flexible display panel and a cover attached to the surface of the flexible display panel. If the hardness of the cover is low, there will be creases after folding and unfolding; if the hardness of the cover is high, It will also affect the bending performance, and it is difficult to ensure that the flexible display panel is bent to a smaller curvature, resulting in a foldable display device that is too thick

The embodiment of the invention discloses a foldable display device. The foldable display device includes a display panel and a flexible cover; the display panel includes a first display part, a second display part and a foldable part; the foldable display device includes a first state and a second state; in the first state, the display The panel and the flexible cover are in the unfolded state, the light-emitting surface of the first display part and the light-emitting surface of the second display part are on the same plane, and the flexible cover covers at least the light-emitting surface of the display panel; in the second state, the display panel is in the first In the folded state, the light-emitting surface of the first display part is folded toward the light-emitting surface of the second display part; the flexible cover is in the second folded state, the flexible cover wraps the display panel, the flexible cover is separated from the light-emitting surface of the display panel, and the flexible cover At least partially covering the non-light-emitting surface of the display panel. The technical solutions of the embodiments of the present invention can avoid stress accumulation during folding, and improve the bending performance of the foldable display device.
Description
technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a foldable display device. Background technique [0002] At present, portable electronic devices (such as mobile phones, tablet computers, etc.) have gradually become people's indispensable carry-on items. With the demand for various entertainment and office functions, people's demand for large-size screens continues to increase. However, the portability of large-size screens will decline. Foldable display devices are increasingly popular due to their advantages of portability and large-size screens. more and more attention. [0003] Existing foldable display devices generally include a flexible display panel and a cover attached to the surface of the flexible display panel. If the hardness of the cover is low, there will be creases after folding and unfolding; if the hardness of the cover is high, It will also affect the bending performance, and it is difficult...
