Abstract

A pixel of a display panel includes a first transistor with a first end coupled to a data line, a control end coupled to a scan line; a second transistor with a first end coupled to a first voltage source, a control end coupled to a second end of the first transistor; a third transistor with a first end coupled to a second end of the second transistor, a control end for receiving a control signal; a light emitting unit with a first end coupled to the second end of the second transistor, a second end coupled to a second voltage source; a first capacitor with a first end coupled to the second end of the first transistor, a second end coupled to a second end of the third transistor; and a second capacitor coupled between the second end of the first capacitor and the second voltage source.
