Abstract
A display for providing information relating to an object relative to the display is disclosed. The display includes a plurality of pixels, and a plurality of light sensors. An individual light sensor of the plurality of light sensors is provided near an individual pixel of the plurality of pixels. An individual light sensor of the plurality of light sensors is configured to detect light. The information relating to the object relative to the display may be provided by correlating the amount of detected light from the plurality of light sensors to the information relating to the object.
Claims19
A display device, comprising:
- a plurality of pixels for generating a display image;
- a plurality of light sensors, wherein each light sensor is positioned near at least one pixel, and wherein each light sensor is configured to sense light;
- and
- a processor coupled to the light sensors configured to determine information associated with an object near the display device based on the light sensed by the light sensors, wherein the processor determines information associated with the light sensed by the light sensors by compensating for the effect of light emitted by the plurality of pixels, wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors;
- wherein the compensation is determined by subtracting the effect of the light emitted by the plurality of pixels;
- and wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors.
A display device, comprising:
- a plurality of pixels for generating a display image;
- a plurality of light sensors, each light sensor being positioned next to at least one pixel, each light sensor being configured to detect light;
- and
- a graphics controller coupled to a processor;
- wherein the processor receives the effect of the plurality of pixels generating the display image from the graphics controller;
- and
- wherein the processor determines information associated with an object near the display device based on subtracting the effect of light emitted by the plurality of pixels from the light levels sensed by the plurality of light sensors, wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with the remainder of the plurality of light sensors.
A method for determining information associated with an object near a display, comprising:
- providing a plurality of light sensors for sensing light, each light sensor being positioned near at least one of a plurality of pixels;
- determining the effect of light emitted from at least a portion of the plurality of pixels;
- sensing a change in light via at least one of the plurality of light sensors due to an object being near the display;
- and
- determining the information associated with the object near the display based on compensating for the effect of the light emitted from the plurality of pixels via the at least one light sensor, wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors ;
- wherein the compensation is determined by subtracting the effect of the light emitted by the plurality of pixels;
- and wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors.
