Abstract: A display includes a scan line, a data line, a pixel circuit, a compensation circuit, a voltage controller, and a data line driver. The data line forms a junction with the scan line. The pixel circuit is disposed at the junction of the scan line and the data line. When the scan line and the data line are driven, the pixel circuit generates a driving current. The compensation circuit generates a comparing signal and a positioning signal based on the driving current. The voltage controller generates a reference voltage that corresponds to the positioning signal with reference to the comparing signal. The data line driver corrects an image signal based on the reference voltage, and drives the data line with the corrected image signal. A compensation circuit for the display is also disclosed.

Abstract: A pixel circuit includes an LED having an anode that receives a driving current and a cathode that receives a scan signal, and a driving circuit including: a switch unit operable according to a voltage signal, and adapted for permitting transfer of a data signal when operating in an on state; a capacitor having a first end coupled to the switch unit, and a second end; a first transistor having a first terminal that is coupled to the second end of the capacitor, a second terminal that is coupled to the anode of the LED, and a control terminal that is coupled to the first end of the capacitor; and a second transistor having a first terminal that is adapted for coupling to the voltage source, a second terminal that is coupled to the first terminal of the first transistor, and a control terminal that is adapted for receiving a reference voltage.
