Abstract

The invention provides a foldable display device. The foldable display device comprises a flexible display panel, a first bottom shell, a second bottom shell, a lifting mechanism and a transmission mechanism. The flexible display panel includes a first display area, a second display area, and a curved display area positioned between the first display area and the second display area. The first bottom shell, the second bottom shell and the lifting mechanism are arranged below the first display area, the second display area and the bent display area respectively. The transmission mechanism is rotationally connected to the lifting mechanism and used for enabling a supporting piece of the lifting mechanism to support the bent display area when the foldable display device is in the unfolded state, so that the bent display area is prevented from collapsing due to finger pressing or wrinkling and layering due to bending.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a foldable display device. Background technique [0002] Flexible display panels, such as organic light emitting diode display panels, can be used to realize foldable display devices due to their flexibility. However, when the existing foldable display device is unfolded, the curved display area in the center of the flexible display panel is not supported. Therefore, when a finger presses the curved display area to perform touch control, the curved display area is likely to collapse. Furthermore, the curved display area is prone to creases after several times of bending, thereby causing peeling. Therefore, it is necessary to provide a foldable display device to solve the problems in the prior art. Contents of the invention [0003] In order to solve the technical problem that the curved display area of ​​the existing foldable display device is easily collapse...
