  • Patent number: 12014674
    Abstract: A display panel includes a pixel circuit, a driving circuit, and a clock signal line. The driving circuit is configured to provide a control signal to the pixel circuit. The clock signal line is configured to provide a clock signal for the driving circuit. A data refresh period of the pixel circuit includes a data writing stage and a holding stage. The holding stage includes N stages arranged in sequence, N?1. When the pixel circuit is operated in the data writing stage, a clock pulse frequency of the clock signal is a first frequency F1. When the pixel circuit is operated in the holding stage, in at least one stage of the N stages, the clock pulse frequency of the clock signal is a second frequency F2.

  • Patent number: 11978391
    Abstract: A display panel includes a pixel circuit. An operation process of the pixel circuit includes a first data refresh period, a data adjustment stage, and a second data refresh period set in sequence, the data adjustment stage includes a first data adjustment stage. The first data adjustment stage includes T1 first sub-data adjustment stages set in sequence, each first sub-data adjustment stage includes m1 data writing frames and n1 holding frames. The operation process of the pixel circuit further includes a first data refresh frequency F21 and a second data refresh frequency F22, and F21<F22. When the pixel circuit is operated at the first data refresh frequency F21, the first data adjustment stage includes T11 first sub-data adjustment stages set in sequence. When the pixel circuit is operated at the second data refresh frequency F22, the first data adjustment stage includes T21 first sub-data adjustment stages set in sequence. T11>T21.
