Abstract
A display device includes a display panel including a plurality of pixels and a plurality of sensors, which are positioned in a display area, a first logic circuit that receives a plurality of illuminance values sensed by the plurality of sensors, and generates illuminance mapping data by mapping the plurality of illuminance values to each of the pixels, and a second logic circuit that corrects image data corresponding to the plurality of pixels based on the illuminance mapping data to generate corrected image data for output to the display panel.
Claims18
A display device comprising:
- a display panel including a plurality of pixels and a plurality of sensors, which are positioned in corresponding areas of a display area;
- a first logic circuit configured to receive a plurality of illuminance values sensed by the plurality of sensors, and to generate illuminance mapping data by mapping the plurality of illuminance values to each of the areas;
- and
- a second logic circuit configured to correct image data corresponding to the plurality of pixels of a given area among the areas based on the illuminance value of the given area in the illuminance mapping data, to generate correction image data for output to the display panel, where each illuminance value corresponds to a light intensity of a corresponding one of the areas,
- wherein a weight used to generate the correction image data for the given area is greater than that used for another area when the illuminance value of the given area is greater than the illuminance value of the other area.
A display device comprising:
- a display panel including a plurality of pixels and a plurality of sensors, which are positioned in a display area;
- and
- a first logic circuit configured to:
- determine a correction weight according to a location within the display area based on a plurality of illuminance values sensed by the plurality of sensors;
- and
- generate correction image data by correcting image data corresponding to the plurality of pixels based on the correction weight for output to the display panel,
- wherein the first logic circuit is configured to:
- determine the correction weight for each of the plurality of pixels;
- and
- generate the correction image data by correcting the image data based on the correction weight.
An electronic device comprising a display device comprising:
- a display panel including a plurality of pixels and a plurality of sensors, which are positioned in a display area including a first area and a second area, and configured to operate in one of a first mode having a first maximum brightness, and a second mode having a second maximum brightness brighter than the first maximum brightness;
- and
- a first logic circuit configured to correct image data corresponding to the plurality of pixels based on a plurality of illuminance values sensed by the plurality of sensors to generate correction image data for output to the display panel,
- wherein, in the second mode, the correction image data for the second area is generated such that a brightness increase applied to the second area is greater than a brightness increase applied to the first area when a measured light intensity in the second area is greater than a measured light intensity in the first area.
