Abstract:
One or more embodiments of the present invention relate to a four color image display device. A display device according to an exemplary embodiment of the present invention includes a first pixel adapted to display a first color, a second pixel adapted to display a second color, a third pixel adapted to display a third color, and a white pixel adapted to display a first white. In one aspect, the first to third pixels are adapted to display a second white in combination, and a ratio of the first white and the second white varies according to a gray. Accordingly, a greenish phenomenon of a low-luminance white light in a four color display device may be reduced.
Abstract:
An organic light-emitting display device and a method of driving the display device are disclosed. A pixel circuit used in the organic light-emitting display device includes a first switching transistor, a second switching transistor and a driving transistor. The first switching transistor switches a data voltage in response to a first control signal. The second switching transistor switches a compensation voltage in response to a second control signal. The driving transistor provides an electric current to an organic light-emitting device in response to the data voltage and the compensation voltage.
