Abstract
The present disclosure relates to a detection circuit, a pixel electrical signal collection circuit, a display panel and a display apparatus, to solve the problem that the current technical solution of detecting whether a flexible display panel is deformed is relatively complex. The detection circuit of an AMOLED based flexible display panel comprises: a plurality of pixel electrical signal collection circuits, each configured to input an electrical signal of a pixel electrode of an organic light emitting diode thereof into an IC through a data collection line; and the IC configured to determine that the flexible display panel is deformed after the electrical signal varies. The embodiments of the present disclosure can detect whether a flexible display panel is deformed by collecting an electrical signal of a pixel electrode of an organic light emitting diode without arranging an individual film structure in the technical solution, thereby reducing the complexity of detecting whether a flexible screen is deformed.
