Abstract

A pixel circuit includes one organic light emitting diode, five first transistors and two capacitors. The first and third transistors have terminals coupled to a first voltage. The second transistor has two terminals coupled to another terminal of the first transistor and a second voltage through the organic light emitting diode, respectively. The first capacitor has a terminal coupled to one terminal of the second transistor. The third transistor has a terminal coupled to one terminal of the first capacitor. The second capacitor has two terminals coupled to a control terminal of the second transistor and another terminal of the first capacitor, respectively. The fourth transistor has two terminals coupled to the terminal of the second transistor and a control terminal of the second transistor, respectively. The fifth transistor has a terminal coupled to the another terminal of the second transistor. A display apparatus is also provided.
