Panel protective layers and display panel device

Abstract

The invention discloses multiple panel protective layers and a display panel device. One protective layer comprises interpenetrating components which are of laminated structures which are connected layer by layer and have spaced gaps; the every two interpenetrating components extend in a mutual penetrating manner side by side; the formed panel protective layer is windable and foldable; and duringunfolding and folding switching, the interpenetrating components are matched to complete the change conversion of the total volume of penetrating. One safe outwards-folding type protective layer comprises a plurality of springs which are wound side by side and extend in sequence; the radius of each spring is greater than or equal to the minimum folding curvature radius of a supported panel; and the formed panel protective layer can enable the supported panel to be safely folded outwards around each spring. One safe inwards-folding type protective layer comprises spring layers which are wound side by side and penetrate a cloth layer; metal strips are arranged at the intersection of spring holes in the cloth layer or the adjacent springs below the cloth layer; and the diameter of each metalstrip is matched with the diameter of a smallest cavity formed by safe inward folding. The invention further provides the display panel device comprising the panel protective layer.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a panel protective layer and a display panel device. Background technique [0002] With the rapid development of science and technology, flexible display screens will be integrated into our lives. Compared with traditional screens, flexible display screens have better flexibility, thinner and thinner, bendable and foldable, easy to store and carry; in wearable display devices , desktop display devices and mobile display devices will play a huge role. However, the flexible display also has a fragile side, such as being unable to withstand large compressive forces and large tensile forces, otherwise the flexible display will be damaged due to excessive force, so the flexible display is not suitable for all aspects during transportation and application. The supporting active structure has demanding requirements. [0003] In the current patents on the safety protectio...

Problems solved by technology

However, the flexible display also has a fragile side, such as being unable to withstand large compressive forces and large tensile forces, otherwise the flexible display will be damaged due to excessive force, so the flexible display is not suitable for all aspects during transportation and application. Supported active structures have demanding requirements

[0003] In the current patents on the safety protection of flexible display screens, especially in the deep bending folding method, most of them use the folded solid support structure for volume retreat and sliding processing, so as to adapt to the length of the flexible display screen and maintain a fixed value without any delay. change, which in turn makes the folding radius formed by the folded rigid support structure larger

In addition, the long-term folding of the fixed-point area also reduces the service life of the overall flexible display
