Light sensitive display
First Claim
Patent Images
1. A display device having a surface for viewing an image comprising:
- a stack of layers configured to display the image; and
a plurality of light sensitive elements included in the stack, the plurality of light sensitive elements configured to detect an object on or near the surface,wherein a processor is configured to detect a touching state of the object based on a region having an inner region and an outer region,wherein the touching state is detected when the inner region is lighter than the outer region and lighter than ambient light reaching the display, and the outer region is darker than the inner region and darker than ambient light reaching the display,a light guide having a surface wherein the processor is configured to detect the touching state of the object relative to the surface of the light guide,wherein the plurality of light sensitive elements are configured to detect a diffusion of light from the light guide due to contact of the object on the light guide.

7. A display device having a surface for viewing an image comprising:
-
a stack of layers configured to display the image; and a plurality of light sensitive elements included in the stack, the plurality of light sensitive elements configured to detect an object on or near the surface, wherein a processor is configured to distinguish between a touching state of the object and a hover state of the object by determining that the object is in the touching state relative to the display device based on detecting a region having an inner region and an outer region, wherein the touching state is detected when the inner region is lighter than the outer region and lighter than ambient light reaching the display, and the outer region is darker than the inner region and darker than ambient light reaching the display; and determining that the object is in the hover state relative to the display device based on detecting the region, wherein the hover state is detected when the inner region and the outer region are darker than ambient light reaching the display, a light guide having a surface wherein the processor is configured to detect the touching state of the object relative to the surface of the light guide wherein the plurality of light sensitive elements are configured to detect a diffusion of light from the light guide due to the touching state of the object on the light guide. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
