Publication number: 20200219443Abstract: An OLED display panel includes subpixels, scanning lines, data lines, a scanning signal output unit, and a data signal output unit. Each subpixel includes a storage capacitor. In the same row of subpixels, the farther a distance away from the scanning signal output unit is, the greater a capacitance value of the storage capacitor in the subpixel is. In the same column of subpixels, the farther a distance away from the data signal output unit is, the greater a capacitance value of the storage capacitor in the subpixel is. The capacitance value of the storage capacitor of the subpixel farther from the data signal output unit is greater in the same column of subpixels. The voltage change caused by the voltage drop is balanced by changing the capacitance value of the storage capacitor, thereby improving the uniformity of the display screen.Type: ApplicationFiled: April 24, 2019Publication date: July 9, 2020Inventors: Kaixiang ZHAO, Di Li
