Abstract

In an OLED display panel provided by the present application, a capacitance value of a first capacitor corresponding to a sub-pixel circuit of at least one color is different from a capacitance value of the first capacitor corresponding to a sub-pixel circuit of another one color in red sub-pixel circuits, green sub-pixel circuits, and blue sub-pixel circuits, so that a capacitance value of the first capacitor corresponding to the green sub-pixel circuits is greatest; in the red sub-pixel circuits, the green sub-pixel circuits, and the blue sub-pixel circuits, a capacitance value of the first capacitor corresponding to the blue sub-pixel circuit is least.
