Reducing deterioration in display quality of a displayed image on a display device

摘要

A display device includes a display portion having gate and source signal lines, and a plurality of pixels, a gate driver that outputs gate signals, a source driver that outputs source signals, and a controller that causes the display portion to display an image at a frame frequency. The controller sets the frame frequency to a first frame frequency F1 when the image is a moving picture, and the controller sets the frame frequency to a second frame frequency F2 lower than F1 when the image is a still picture. The gate driver outputs the gate signals to the gate signal lines in an aligned order of gate signal lines in a second direction when the frame frequency is F1, and the gate driver outputs the gate signals to the gate signal lines in different order from the array order when the frame frequency is F2.

1. A display device comprising:
a display portion including a plurality of gate signal lines extending in a first direction and aligned in a second direction intersecting the first direction, a plurality of source signal lines extending in the second direction and aligned in the first direction, and a plurality of pixels connected to the source signal lines and the gate signal lines, the display portion configured to display an image at a frame frequency for each frame; a gate driver configured to output gate signals to the gate signal lines sequentially; a source driver configured to output source signals to the pixels connected to the gate signal lines to which the gate signals are outputted, the source signals configured to display the image through the source signal lines; and a controller configured to control the gate driver and the source driver to cause the display portion to display the image at the frame frequency for each frame, wherein: the controller sets the frame frequency to a first frame frequency F1 when the image is a moving picture, and the controller sets the frame frequency to a second frame frequency F2 lower than the first frame frequency F1 when the image is a still picture, the controller once switches the frame frequency from the first frame frequency F1 to an intermediate frame frequency F3 (F1>F3>F2) and then, further switches the frame frequency from the intermediate frame frequency F3 to the second frame frequency F2, when switching the image signal from the moving picture signal to the still picture signal causes the frame frequency to be switched from the first frame frequency F1 to the second frame frequency F2, and the gate driver outputs the gate signals to the gate signal lines in an aligned order of the gate signal lines in the second direction when the frame frequency is the first frame frequency F1, and the gate driver outputs the gate signals to the gate signal lines in a different order from the aligned order of the gate signal lines when the frame frequency is the second frame frequency F2.
