Patent ID: 8610749

Claim:
A display device including a plurality of scanning lines extended in one direction, a plurality of data signal lines extended in another direction, a source driver circuit for driving the plurality of data signal lines, a gate driver circuit for controlling the plurality of scanning lines, and a pixel provided correspondingly to each intersection between the plurality of scanning lines and the plurality of data signal lines, each pixel being provided with an element for emitting light with luminance depending on an electric current supplied to the element, where a selection period of a scanning line is a period in which the scanning line is selected by the gate driver circuit, the display device comprising: a pixel circuit per pixel, the pixel circuit configured to be driven in an impulse mode in which the element emits the light only during the selection period, and in a hold mode in which the element emits the light not during the selection period but after the selection period, in a case where whole gray scales of a light emitting signal are classified into lower-side gray scales and higher-side gray scales, the pixel circuit being driven (i) solely in the impulse mode when a display is carried out at a lower-side gray scale indicated by the light emitting signal and (ii) solely in the hold mode when a display is carried out at a higher-side gray scale indicated by the light emitting signal, the source driver circuit being provided with a first signal source for supplying the light emitting signal when the pixel circuit is driven in the impulse mode, a second signal source for supplying the light emitting signal when the pixel circuit is driven in the hold mode, and switching means, and for the pixel displaying an image in the impulse mode, the switching means connecting a corresponding one of the data signal lines with the first signal source, and for the pixel displaying an image in the hold mode, the switching means connecting a corresponding one of the data signal lines with the second signal source.
