Abstract
Disclosed herein is a pixel circuit for an OLED panel, a display device having the pixel circuit and a method of driving the OLED panel. The pixel circuit for an OLED panel includes a switching element driven by a scan signal input through a corresponding one of scan lines sequentially selected from among a plurality of scan lines, and configured to transfer drive current based on luminance data input through a corresponding one of a plurality of data lines. An OLED emits light using the drive current transferred by the switching element. The OLED has an anode connected to a source terminal of the transistor and a cathode connected to a common electrode. Accordingly, problems such as the imbalance and deterioration of luminance attributable to the sequential driving of scan lines can be solved, and the complexity of circuits of a conventional AMOLED panel can be solved.
