DISPLAY DRIVING CIRCUIT, DISPLAY DEVICE, AND DISPLAY DRIVING METHOD

摘要

Disclosed is a display device that performs CC driving, wherein a first mode in which images are displayed by doubling the resolution of video signals in the longitudinal direction is switched to a second mode in which images are displayed at the resolution of the video signals. In the first mode, signal potentials of the same polarity and of the same gradation are supplied to pixel electrodes included in two adjacent pixels arranged in the longitudinal direction corresponding to two adjacent scanning signal lines such that directions of change of the signal potentials written in the pixel electrodes differ every two adjacent rows (two line inversion driving). In the second mode, the directions of change of the signal potentials written in the pixel electrodes differ every row (one line inversion driving). Also disclosed is a display driving circuit capable of mutually switching modes between a first mode in which images are displayed by multiplying the resolution of video signals by n times (n is an integer) and a second mode in which images are displayed by multiplying the resolution of the video signals by m times (m is an integer and differs from n) in a display device that performs CC driving without causing a reduction in display quality.
