Abstract
The embodiment of the invention discloses a display panel and a display device.The display panel comprises a middle frame and a backboard, the middle frame comprises a first face and a second face which are oppositely arranged, a through hole is formed in the middle frame, and the through hole penetrates through the middle frame; wherein the middle frame comprises a first middle sub-frame and a second middle sub-frame which are symmetrically arranged relative to the through hole, and the end faces of the ends, close to the through hole, of the first middle sub-frame and the second middle sub-frame are both arranged in an arc shape. Therefore, the stress at the bending position of the display panel can be evenly spread, the stress concentration phenomenon at the bending position of the display panel is relieved, the stress borne by the display panel in the bending process is reduced, the fatigue life of the display panel can be prolonged, and development of the water drop type display panel with the small bending angle is facilitated.
Description
technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] At present, in the modern communication industry, the market demand for mobile phones, TVs, tablets, notebooks, digital cameras and other products is increasing, and various display devices are also developing towards being bendable. [0003] Among them, the water drop type bending is favored by the market because of its space utilization, but the water drop type is limited due to the stress concentration at the bending point, which not only affects the bending angle of the water drop type bending screen, but also affects the water drop type bending. The service life of the folding screen. [0004] Therefore, how to alleviate the stress concentration phenomenon at the bend of the display panel is a difficult problem that panel manufacturers need to work hard to overcome.
