Title:
DISPLAY PANEL AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/126587
Kind Code:
A1
Abstract:
A display panel and a driving method therefor, and a display device. The display panel comprises: a plurality of pixel islands (10, AA11-AA33), each of the plurality of pixel islands (10, AA11-AA33) comprising a plurality of sub-pixels (111, 121, 131); a plurality of control signal lines (G1, G2, G3…); a plurality of switching signal lines (D_I1, D_I2, D_I3…); a plurality of light-emitting signal lines (D_T11, D_T12, D_T13, D_T21, D_T22, D_T23, D_T31, D_T32, D_T33…); and a sub-pixel driving circuit provided for each of the plurality of sub-pixels (111, 121, 131). The plurality of light-emitting signal lines (D_T11, D_T12, D_T13, D_T21, D_T22, D_T23, D_T31, D_T32, D_T33…) are configured to: under the control of switching signals provided by the plurality of switching signal lines (D_I1, D_I2, D_I3…) and control signals provided by the plurality of control signal lines (G1, G2, G3…), sequentially write working gray-scale level signals corresponding to particular gray-scales to corresponding sub-pixels (111, 121, 131) in multiple times in ascending order of gray-scale within one display time frame, wherein different working gray-scale level signals indicate that durations during which the light-emitting signal lines (D_T11, D_T12, D_T13, D_T21, D_T22, D_T23, D_T31, D_T32, D_T33…) provide working gray-scale level signals to an organic light-emitting diode (E) by means of a second transistor (M2) are different, and the final display gray-scale of each of the plurality of sub-pixels (111, 121, 131) in the plurality of pixel islands (10) is a gray scale obtained by superposition of the different working gray-scale level signals.
