Abstract

The invention relates to a detection circuit, a pixel electric signal acquisition circuit, a display panel and a display device to solve the problem of a complicated conventional technical scheme in which people detect whether a flexible display panel deforms. A detection circuit based on an AMOLED flexible display panel includes multiple pixel electric signal acquisition circuits and an integrated circuit IC, wherein the pixel electric signal acquisition circuits are used for inputting electric signals of pixel electrodes of organic light-emitting diodes in the pixel electric signal acquisition circuits to the IC through data acquisition wires, and the IC is used for determining whether the flexible display panel deforms after the electric signals change. According to the embodiment, people detect whether the flexible display panel deforms by acquiring the electric signals of the pixel electrodes of the organic light-emitting diodes. Through the technical scheme, no independent film structure needs to be arranged, so the complexity of detecting whether a flexible screen deforms is reduced.

Description

technical field [0001] The 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 acquisition circuit, a display panel and a display device. Background technique [0002] With the advancement of display technology, more and more flexible display panels have entered the market. Compared with traditional display panels, flexible display panels are more and more popular due to their thinness, bendability or even curling, and good mechanical properties. favor. [0003] At present, the flexible display panel quickly operates the application in the device through deformation. However, in the prior art, the detection of whether the flexible display panel is deformed is usually by using a special macromolecular piezoelectric material. In this technical solution, an independent The film layer structure and special circuit are used to cooperate....
