Abstract
An active-matrix organic light-emitting diode (AMOLED) compensation pixel circuit is provided. The pixel circuit is configured to include an OLED element, three switching transistors, one driving transistor, and two capacitors. This configuration allows the voltage applied to the gate of the driving transistor to change in proportion to the area of the display screen, thereby increasing the current flowing through the OLED. This enables compensation for luminance reduction while also automatically compensating for luminance reduction caused by power supply voltage drops.
