Abstract

The invention provides a display panel and a method for detecting bending degree of a bending region. The display panel comprises n deformation detecting units, wherein at least part of the deformation detecting units are arranged in the bending region, the deformation detecting units are distributed in a line in the bending direction of the display panel; the deformation detecting units comprisea first strip-shaped semiconductor, a second strip-shaped semiconductor, a first resistor element and a second resistor element which are arranged in a bridge-arm shape and have the connection mode of(first strip-shaped semiconductor)-(second resistor element)-(second strip-shaped semiconductor)-(first resistor element)-(first strip-shaped semiconductor); equivalent resistance values of the firststrip-shaped semiconductor and second strip-shaped semiconductor change along with the change of own bending degrees thereof, and the resistance values of the first resistor element and second resistor element do not change along with the change of deformation amounts of the bending area, therefore, the problem of uneven brightness of a displayer under a bending state is solved by accurately calculating the bending degree of each position of the display panel can be solved.

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 ...
