摘要： A liquid crystal display device includes: first and second liquid crystal panels disposed to be overlapped with each other; a parallax reduction unit that generates the second output image signal by performing smoothing processing on a first signal based on the input image signal; a first temporal filter that generates a first response correction signal determining the first output image signal based on the second output image signal; and a corrector that generates the first output image signal based on at least the first response correction signal and a second signal based on the input image signal. The first temporal filter generates the first response correction signal of a current frame based on the second output image signal of the current frame and the first response correction signal of a previous frame.

摘要： A controller in an intermediate inversion drive mode causes a source driver to alternate polarities of voltages applied to pixel electrodes connected to one of source signal lines per plural gate signal lines, and to apply the voltages so that a pair of the pixel electrodes, which are connected to one of the gate signal lines and to source signal lines adjacent to each other, are subjected to different voltage application in polarity from each other, the source driver alternating polarities of the voltages applied to the respective pixel electrodes for each frame. When the source driver, in the intermediate inversion drive mode, applies the voltages sequentially to the pixel electrodes connected to one of the source signal lines, the controller sets a longer voltage application period for the inverted electrode than for the equivalent electrode.

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.
