DISPLAY DEVICE INCLUDING OPTICAL SENSOR IN PIXEL

Abstract

In order to maintain display performance of a display device, the display device includes an optical sensor disposed across three sub-pixels of red, green and blue colors in each pixel. This configuration makes it possible to adjust the aperture ratios of the respective sub-pixels, and thus to make the amount of light passing through the respective sub-pixels closer to one another. In other words, the white balance can be maintained.

Claims

1. A display device comprising: a pixel region having a plurality of pixels;three sub-pixels of red, green and blue colors disposed in each of the pixels; andan optical sensor disposed across the three sub-pixels.

2. A display device comprising: a pixel region having a plurality of pixels;three sub-pixels of red, green and blue colors disposed in each of the pixels;an optical sensor disposed in any one of the three sub-pixels; anddummy patterns respectively disposed in the sub-pixels, in each of which the optical sensor is not disposed.

3. A display device comprising: a pixel region having a plurality of pixels;three sub-pixels of red, green and blue colors disposed in each of the pixels, and any one of which three sub-pixels has an area larger than the other two sub-pixels; andan optical sensor disposed in the sub-pixel having the larger area.
