The present application provides a display panel and a method for detecting the bending degree of the bending area. The display panel includes: n deformation detection devices at least partially arranged in the bending area and distributed in a straight line along the bending direction of the display panel. Unit; the deformation detection unit is the first strip-shaped semiconductor, the second strip-shaped semiconductor, the first resistance element and the second resistance element arranged in the form of a bridge arm; its connection mode is: the first strip-shaped semiconductor-the second resistance element - second semiconductor strip - first resistive element - first semiconductor strip. Wherein, the equivalent resistance values of the first strip-shaped semiconductor and the second strip-shaped semiconductor change according to their curvature, and the resistance values of the first resistance element and the second resistance element do not follow the bending area. deformation changes. Therefore, the above solution can solve the problem of uneven brightness of the display in the bent state by accurately calculating the bending degree of each position of the display panel.
Description
technical field [0001] The present invention relates to the technical field of display devices, in particular to a method for detecting the bending degree of a display panel and a bending area. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable important tool missing. [0003] The main component of electronic equipment to realize the display function is the display panel. With the continuous advancement of technology and the continuous improvement of people's needs, foldable flexible display panels have emerged as the times require. After the flexible display panel is bent, the light-emitting devices inside the display panel Spacing will vary, so display compensation for the bend area is required. However, since the bending conditions at ...
