Title
(EN) Folding display panel
(ZH) 折叠显示面板
Abstract
(EN) An embodiment of the invention provides a folding display panel. The folding display panel comprises a metal supporting layer, a display module arranged on the surface of the metal supporting layer, atouch layer arranged on the surface of the display module and a polarizing cover plate layer arranged on the surface of the touch layer, wherein the folding display panel comprises a display area, aplurality of sections of folding areas are arranged in the display area, and the metal supporting layer is provided with hollow-out patterns in the folding areas; the metal supporting layer is made ofsus stainless steel; the thickness of the sus stainless steel ranges from 10 microns to 30 microns, so the supporting function of the folding display panel is achieved; the hollowed-out patterns caneffectively avoid concentration or non-uniformity of folding stress, so the bending stress of the whole structure is small in the bending process, and the cracking risk of a film layer of the foldingdisplay panel is reduced; and therefore, the flexibility and stability of the folding display panel are improved.
(ZH) 本申请实施例提供一种折叠显示面板,本申请中折叠显示面板包括金属支撑层、设于金属支撑层表面的显示模组、设于显示模组表面的触控层以及设于触控层表面的偏光盖板层;其中,折叠显示面板包括显示区,显示区内设置有多段折叠区域,金属支撑层在折叠区域中设置有镂空图案;该金属支撑层的材料为sus不锈钢,且该sus不锈钢的厚度为10um至30um范围内满足折叠显示面板的支撑功能,镂空图案可以有效避免折叠应力集中或者不均匀,以使弯折中使整个结构的弯折应力较小,降低折叠显示面板膜层开裂的风险,从而提高折叠显示面板柔韧性和稳定性。
