Patent ID: 8350796

Claim:
A display device for displaying an image, said display device comprising: a display section, provided by a liquid crystal display (LCD), configured to display the image with a luminance in accordance with a display signal voltage, the display section including pixels, each pixel in the LCD including a first subpixel and a second subpixel that are connected to a same source line and same gate line; and a control section configured to divide each frame into first to m-th subframe periods, m being an integer greater than or equal to two, the control section configured to generate first to m-th display signals for the first to m-th subframe periods for output to the display section such that dividing each frame into the first to m-th subframe periods does not change a sum luminance output of the display section within each frame; wherein the control section creates a difference between a luminance of the first subpixel and a luminance of the second subpixel, wherein each subpixel is connected to a different auxiliary line and includes a pixel capacitance, a switching element, and an auxiliary capacitance, the switching element applying, to the pixel capacitance, a display signal applied to the source line when the gate line turns ON, the auxiliary capacitance being connected to the pixel capacitance and a respective auxiliary line, wherein the control section creates an auxiliary signal in a different state for each subpixel, the auxiliary signal being supplied to the first and second subpixels through the respective auxiliary lines, and adjusts a polarity of the display signal voltage to control a relationship between levels of the luminances of the first and second subpixels, wherein the control section reverses the polarity of the display signal voltage at a frame cycle and inverts, in a frame, the state of the auxiliary signal supplied to each subpixel, and wherein the control section inverts, at a subframe cycle, the state of the auxiliary signal supplied to each subpixel.
