Abstract
The display device includes a circuit and multiple pixels. Each pixel includes multiple sub-pixels, and each sub-pixel includes a pixel electrode and a portion of a common electrode. A frame period includes a first polarity period and a second polarity period. The circuit maintains a voltage of the common electrode unchanged during the frame period, and applies a first dot inversion mode in the first polarity period and applies a second dot inversion mode in the second polarity period to the pixel electrodes. If determining that the input image has a bright stripe and the dark stripe adjacent to the each other, the circuit increases an intensity of the sub-pixel in an edge of the dark stripe or the bright stripe, and/or decrease an intensity of the middle sub-pixel in the bright stripe.
