Abrégé
(EN)
The invention provides an OLED display panel. The OLED display panel includes a plurality of sub-pixels, a plurality of scan lines, a plurality of data lines, a scan signal output unit, and a data signal output unit; a plurality of sub-pixel can be subjected to array assignment, each row of sub-pixels is provided with the scan line electrically connected to the row of sub-pixels, and each column of sub-pixels is provided with the data line electrically connected to the column of sub-pixels, the scan signal output unit is electrically connected to the plurality of scan lines, and the data signal output unit is electrically connected to the plurality of data lines; each of the sub-pixels includes a storage capacitor; in the same row of sub-pixels, a capacitance value of the storage capacitorof the sub-pixel which is farther from the scan signal output unit is larger; in the same column of sub-pixels, a capacitance value of the storage capacitor of the sub-pixel which is farther from thedata signal output unit is larger, the change in the capacitance value of the storage capacitor is used, the voltage change caused by the voltage drop is balanced, and the uniformity of the display frame is increased.
