The invention discloses a supporting plate, a folding display panel and a folding display device. According to one specific implementation mode, the supporting plate for a folding display module comprises a bottom plate and side plates formed by extending upwards from the edge of the bottom plate; the side plate is provided with a first area corresponding to the folding area of the folding displaymodule and a second area corresponding to the non-folding area of the folding display module, the first area and the second area respectively comprise a foldable rigid layer, and the height of the foldable rigid layer of the first area is smaller than that of the foldable rigid layer of the second area. According to the supporting plate of the embodiment, dust particles entering a gap between thehinge of the folding display device and the folding display panel and the gap existing in the hinge can be effectively prevented from entering a film layer of the folding display module, the performance of the folding display module is guaranteed, and the service life of the folding display module is prolonged.
Description
technical field [0001] The present application relates to the technical field of folding display. More specifically, it relates to a support plate, a folding display panel and a folding display device. Background technique [0002] Compared with conventional display devices, the folding display device can achieve a larger display area or a smaller carrying size due to its folding characteristics, thereby bringing better user experience to users. [0003] In the prior art, the folding of the folding display device is mainly controlled by the hinge. There are certain gaps between the hinge and the folding display panel and the hinge itself. External dust particles can easily enter the folding display device through these gaps, or even go deep into the folding display device. The interior of each film layer of the display module leads to poor dustproof performance of the folding display device, which affects the display effect and service life of the folding display module. ...
