Abstract:
1. An active matrix type display device in which a current-driven emissive element is provided in each of a plurality of pixels arranged in a matrix, and a current of the emissive element is controlled using a drive TFT so as to perform sequential display of a plurality of images having a predetermined frame period, the display device comprising: an image lag alleviating function that, when turned on, applies an opposite bias voltage between a gate electrode and a source electrode of the drive TFT; a first detector for detecting whether or not a first image of the plurality of images includes a uniform portion having an intermediate tone; a second detector for detecting motion of the first image from a previous image of the plurality of images; and a microcomputer to turn on the image lag alleviating function for a preset time when the first detector detects that the first image of the plurality of images includes a uniform portion having an intermediate tone and the second detector detects motion of the first image from a previous image of the plurality of images, wherein when the image lag alleviating function is turned on, a signal level of the first image is increased by multiplying the signal when the image lag alleviating function is turned off by a ratio of (one frame period/lights-on period within one frame period).
