Abstract

The application discloses a display apparatus and a deformation detection method thereof used to detect the deformation of the display apparatus. A flexible display apparatus provided in the embodiment of the application includes a flexible substrate, a display device and a piezoelectric sensor stacked together. The piezoelectric sensor includes a first electrode, a second electrode, and a piezoelectric layer located between the first electrode and the second electrode. The piezoelectric sensor is configured to generate an electrical signal under the stress generated by the bending of the flexible display apparatus in order to determine the deformation parameters of the flexible display apparatus.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a deformation detection method thereof. Background technique [0002] Active-matrix organic light-emitting diode (AMOLED) display devices have attracted much attention due to their advantages of bright colors, good viewing angles, high contrast, fast response, and low power consumption. Flexible AMOLED display devices have a wider application prospect in the future display field, and have broad application space in multiple display fields such as mobile display, vehicle display, and medical display. However, the flexible AMOLED display device in the prior art cannot use the device itself to detect the stress change when it is deformed, cannot determine the degree of bending of the display device, cannot avoid excessive bending of the display device, and cannot use the bending of the display device to develop a display device new features. Conten...
