摘要： Embodiments of the present disclosure provide a display panel and a drive method thereof, and a display device. The display panel includes a plurality of sets of pixel columns and a plurality of drive circuits. Each of the sets of pixel columns includes a plurality of subpixel columns. The plurality of drive circuits correspond to the plurality of sets of pixel columns respectively. Each of the drive circuits is further configured to send, to an adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the drive circuit, and/or receive, from the adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the adjacent drive circuit and generate a data signal for driving the subpixel column in the set of pixel columns of the drive circuit, based on the received source data signal.

摘要： Embodiments of the present disclosure provide an OLED display panel and a driving method thereof. The OLED display panel includes a plurality of power lines, each power line connecting to a plurality of pixels, and one end of each power line connecting to a power source. The method includes acquiring a current value of the power line and comparing it to a preset threshold, when a current value of the power line is less than or equal to the threshold, providing an original data voltage to the pixels connected to the power line, when a current value of a power line is greater than the threshold, providing a compensating data voltage to the pixel connected to the power line. The compensating data voltage is equal to the difference between the original data voltage and the compensation voltage.
