Abstract
The present disclosure provides a compensation method, device, circuit for a display panel, a display panel and a display device. The display panel includes a plurality of pixel circuits, each of which comprises a driving transistor. The compensation method includes: obtaining a first compensation grayscale value GLand a second compensation grayscale value GLof a pixel circuit to be compensated; obtaining a first compensation luminance L, a first gate-source voltage Vof the driving transistor, a second compensation luminance L, and a second gate-source voltage Vof the driving transistor, wherein Land Vcorrespond to GL, and Land Vcorrespond to GL; obtaining a theoretical luminance L corresponding to an input grayscale value GL; calculating the compensation gate-source voltage V'by using L, L, V, L, and V; and obtaining an output compensation grayscale value GL′ according to V′.
