Abstract

The embodiment of the invention provides a display device and a control method thereof. The display device comprises a display panel, a shell and at least one movement mechanism. The movement mechanism is connected with the display panel and used for controlling the display panel to move relative to the shell. In the flattening state, the bending part of the shell is overlapped with the first branch part of the display panel; in the bending state, the bending part drives at least part of the first subsection to be bent, and the non-bending part of the shell drives the second subsection of the display panel to be stacked; the bending state comprises a first bending state and a second bending state; in the first bending state, the bending part comprises a first site, the first branch part comprises a second site, and the second site is located on a normal line passing through the first site; in the second bending state, the second site is not located on the normal line passing through the first site. According to the display device, the relative position between the display panel and the shell can be finely adjusted, so that the part, bearing the maximum bending stress, in the display panel changes in a certain area, and the folding service life of the display device is prolonged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] The development of flexible display technology has promoted the diversification of display devices, making foldable display devices possible. Compared with conventional display devices, the foldable display device has great freedom in shape, which increases the portability of the display device and expands the usage scenarios of the display device. In the prior art, it is necessary to preset a fixed bending area in the flexible display panel, and the bending area in the flexible display panel will bend when the display device is folded; when the display device is flattened, the bending area in the flexible display panel Then flatten. Existing foldable devices generally require a bending life of 200,000 times. In fact, the display panel may have creases or even more serious screen damage under ...
