Abstract

The invention relates to a detection circuit, a pixel electric signal acquisition circuit, a display panel and a display device, which are used to solve the problem that the current technical solution for detecting whether a flexible display panel is deformed is relatively complicated. Wherein, the detection circuit based on the AMOLED flexible display panel includes: a plurality of pixel electrical signal acquisition circuits for inputting the electrical signal of the pixel electrode of the organic light emitting diode in the pixel electrical signal acquisition circuit to the IC through the data acquisition line, and a plurality of pixel electrical signal acquisition circuits for After the electrical signal changes, the integrated circuit IC that determines the deformation of the flexible display panel. The embodiment of the present invention can detect whether the flexible display panel is deformed by collecting the electrical signal of the pixel electrode of the organic light-emitting diode. Complexity.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a detection circuit based on an active matrix organic light emitting diode flexible display panel, a pixel electrical signal collection circuit, a display panel and a display device. Background technique [0002] With the advancement of display technology, more and more flexible display panels enter the market. Compared with traditional display panels, flexible display panels are more and more popular for their lightness, thinness, bendable or even curled, and good mechanical properties. Favor. [0003] At present, the flexible display panel can quickly operate the application in the device through deformation. However, the detection of whether the flexible display panel is deformed in the prior art is usually through the use of special macromolecular piezoelectric materials. In this technical solution, independent This kind of technical solution for detecting whether the flex...
