Abstract
A display device includes a display panel including a display area in which an optical area and a normal area are disposed, and a non-display area, a first optical electronic device disposed to overlap the optical area and generating user information, and a display controller configured to acquire information on a viewing angle at which images on the display panel can be acceptably viewed based on the user information, and adjust a ratio between red, green, and blue colors in an image displayed in the optical area among the images displayed in the display area based on the viewing angle information.
Claims20
A display device comprising:
- a display panel comprising a display area in which an optical area and a normal area are disposed, and a non-display area;
- a first optical electronic device disposed to overlap with the optical area and configured to generate user information;
- and
- a display controller configured to acquire viewing angle information on a viewing angle at which images on the display panel are viewed based on the user information generated by the first optical electronic device, and adjust a ratio between red, green, and blue colors in an image displayed in the optical area among the images displayed in the display area based on the acquired viewing angle information without affecting a ratio between red, green, and blue colors of an image displayed in the normal area,
- wherein the optical area is configured not to include a cathode electrode.
A display device comprising:
- a display panel comprising a display area in which an optical area and a normal area are disposed, and a non-display area;
- a first optical electronic device disposed to overlap with the optical area and configured to generate user information;
- and
- a display controller configured to acquire viewing angle information on a viewing angle at which images on the display panel are viewed based on the user information generated by the first optical electronic device, and adjust a ratio between red, green, and blue colors in an image displayed in the optical area among the images displayed in the display area based on the acquired viewing angle information without affecting a ratio between red, green, and blue colors of an image displayed in the normal area,
- wherein the first optical electronic device has a driving frequency that is smaller than a driving frequency of the display device, and
- wherein the first optical electronic device generates the user information at discontinuous frames of the display device.
A method of driving a display device comprising a display panel comprising a display area comprising an optical area and a normal area, and a non-display area, the method comprising:
- generating user information using image information supplied by a first optical electronic device disposed to overlap with the optical area;
- generating viewing angle information on a viewing angle at which images on the display panel are viewed based on the user information;
- and
- while displaying the images on the display panel, adjusting a ratio between red, green, and blue colors in an image displayed in the optical area by adjusting luminance of pixels present in the optical area of the display panel based on the viewing angle information without affecting a ratio between red, green, and blue colors of an image displayed in the normal area,
- wherein the generating of the viewing angle information comprises predicting a location of a user using the user information and one or more algorithms, and generating predicted viewing angle information based on the predicted location of the user.
