摘要： The present disclosure proposes an OLED display panel, and a driving method and driving circuit thereof. After grayscale data of a pixel in an image to be displayed is acquired and aging degree of the pixel is determined, a data compensation coefficient of the pixel is determined according to both the grayscale data of the pixel and the aging degree of the pixel. Then, the grayscale data of the pixel is compensated using the determined data compensation coefficient. Finally, the pixel is driven using the compensated grayscale data.

摘要： The present disclosure provides a pixel structure, a display panel, and a display apparatus. The pixel structure includes a plurality of subpixels. The subpixels include red subpixels, green subpixels, and blue subpixels. The red subpixels and the green subpixels are all substantially in an isosceles triangular shape and have substantially a same area. Each blue subpixel is in substantially a rhombic shape and has an area substantially twice the area of the red subpixel or green subpixel. Each leg of the isosceles triangular shape of the red or green subpixel has a length equal to a side length of the rhombic shape of the blue subpixel. The display panel using the subpixel rendering algorithm has visual resolution greater than physical resolution. The enlarged blue subpixel extends life span to make all three color subpixel have similar life span.

摘要： The NAND gate circuit includes at least two input transistors, at least two pull-up modules and at least two input control transistors. A first electrode of each input transistor is connected to a second level output end via the pull-up module. The input control transistor is configured to enable a potential of the control end of the pull-up module connected to the first electrode of the input transistor to be the first level when the input signal connected to the gate electrode of the input control transistor is at a second level. The at least two pull-up modules are configured to cut off the connection between the second level output end and the NAND gate output end when all the input signals are at the second level, and enable the connection therebetween when none of the input signals is at the second level.
