Title:
DISPLAY PANEL, DISPLAY DEVICE AND COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/205574
Kind Code:
A1
Abstract:
A display panel (10), a display device (1) and a compensation method. The display panel (10) comprises: a plurality of sub-pixels arranged in a plurality of rows and a plurality of columns, each sub-pixel comprising a pixel circuit (100); a plurality of sensing drive lines (Se) respectively connected to pixel circuits (100) of the plurality of sub-pixels; and a sensing driver (12) connected to the plurality of sensing drive lines (Se). The pixel circuit (100) comprises a light-emitting element; and the sensing driver (12) is configured to sense, via the plurality of sensing drive lines (Se), electrical parameters of light-emitting elements of the pixel circuits (100) of the plurality of sub-pixels, and is configured to generate a compensation signal according to the electrical parameters and transmit the compensation signal to the pixel circuits (100) of the plurality of sub-pixels via the plurality of sensing drive lines (Se). The display panel (10) can multiplex the sensing drive lines (Se) to complete sensing and the compensation for a threshold voltage drift of a driving transistor.
