DISPLAY DEVICE, METHOD FOR DRIVING THE SAME, AND ELECTRONIC APPARATUS

摘要

According to an aspect, a display device includes: an image display panel in which pixels are arranged in a two-dimensional matrix, each of the pixels including a first sub-pixel displaying a first color, a second sub-pixel displaying a second color, a third sub-pixel displaying a third color, and a fourth sub-pixel displaying a fourth color; and a signal processing unit that converts input values of input signals into extended values in an extended color space to generate output signals, and outputs the generated output signals to the image display panel. The signal processing unit changes the output signals for the first to fourth sub-pixels based on at least saturation of the input signals.

1. A display device comprising:
an image display panel in which pixels are arranged in a two-dimensional matrix, each of the pixels including a first sub-pixel that displays a first color, a second sub-pixel that displays a second color, a third sub-pixel that displays a third color, and a fourth sub-pixel that displays a fourth color; and a signal processing unit that converts input values of input signals into extended values in a color space extended with the first color, the second color, the third color, and the fourth color to generate output signals, and outputs the generated output signals to the image display panel, wherein each of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel includes a pixel electrode that is supplied with a video signal and reflects light incident thereon from a front surface of the image display panel, the signal processing unit
obtains an output signal for the first sub-pixel based on at least an input signal of the first sub-pixel and an expansion coefficient and outputs the obtained output signal to the first sub-pixel,obtains an output signal for the second sub-pixel based on at least an input signal of the second sub-pixel and the expansion coefficient and outputs the obtained output signal to the second sub-pixel,obtains an output signal for the third sub-pixel based on at least an input signal of the third sub-pixel and the expansion coefficient and outputs the obtained output signal to the third sub-pixel, andobtains an output signal for the fourth sub-pixel based on the input signal of the first sub-pixel, the input signal of the second sub-pixel, the input signal of the third sub-pixel, and the expansion coefficient and outputs the obtained output signal to the fourth sub-pixel; and the signal processing unit changes the output signal for the first sub-pixel, the output signal for the second sub-pixel, the output signal for the third sub-pixel, and the output signal for the fourth sub-pixel based on at least saturation of the input signals.
