Abstract:
Red, green, and blue organic electroluminescent (EL) elements formed on a pixel in an organic EL display are driven by a driving transistor. A capacitor is coupled between a gate and a source of the driving transistor to maintain a voltage for a predetermined time. Emission control transistors are coupled between the driving transistor and the red, green, and blue organic EL elements, respectively. One field is divided into three subfields, and one of the red, green, and blue organic EL elements in each pixel starts to emit light in each subfield to thus represent a full color screen. The red, green, and blue are mixed and emitted in the row direction and column direction in each of the subfields of a field.
