Display control device, display device and method of controlling display device

A display device, comprising:

• a display unit having a plurality of pixels each including a first sub-pixel of a first color, a second sub-pixel of a second color, a third sub-pixel of a third color and a fourth sub-pixel of a fourth color;
• and
• a display control device for controlling the display device, the display control device comprising:
• an input part receiving an input signal including gray levels of the first color, the second color and the third color constituting a color for each of the plurality of pixels;
• a selection part selecting at least one of the plurality of pixels as a selection pixel and other of the plurality of pixels as a non-selection pixel;
• and
• an output part outputting an output signal controlling luminances of the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel based on the input signal,
• wherein at least one of the first sub-pixel, the second sub-pixel and the third sub-pixel of the non-selection pixel is controlled to have a luminance of 0 according to the output signal,
• wherein the fourth sub-pixel of the selection pixel is controlled to have a luminance of 0 according to the output signal.

A method of controlling a display device including a display unit having a plurality of pixels each including a first sub-pixel of a first color, a second sub-pixel of a second color, a third sub-pixel of a third color and a fourth sub-pixel of a fourth color, comprising:

• inputting an input signal including gray levels of the first color, the second color and the third color constituting a color for each of the plurality of pixels;
• selecting at least one of the plurality of pixels as a selection pixel and other of the plurality of pixels as a non-selection pixel;
• and
• outputting an output signal controlling luminances of the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel based on the input signal,
• wherein at least one of the first sub-pixel, the second sub-pixel and the third sub-pixel of the non-selection pixel is controlled to have a luminance of 0 according to the output signal, and
• wherein the fourth sub-pixel of the selection pixel is controlled to have a luminance of 0 according to the output signal.
