Abstract
There is provided a display device in which disadvantageous effects due to unnecessary operations of an image lag alleviating function are minimized. In a display device of active matrix type, for each of the pixels arranged in a matrix, a current-driven emissive element is provided, and the current of the emissive element is controlled using a drive TFT so as to perform display. While a black display period during which an opposite bias voltage is applied between the gate electrode and the source electrode of the drive TFT is inserted in order to alleviate image lag, this insertion is performed only when a predetermined condition is satisfied, and is performed for a certain duration according to a command by a microcomputer (10).
Claims7
An active matrix type display device in which a current-driven emissive element is provided in each of pixels arranged in a matrix, and a current of the emissive element is controlled using a drive TFT so as to perform display,
- the display device comprising means for alleviating image lag by periodically applying an opposite bias voltage between a gate electrode and a source electrode of the drive TFT,
- wherein the means for alleviating image lag operates for a certain duration when a predetermined condition is satisfied.
