Abstract
A display device includes: a substrate; a display layer disposed on the substrate and including a plurality of light emitting areas; a code pattern layer disposed on the display layer and including a plurality of position code patterns; and a reflective layer that receives first light incident from the outside having a first wavelength band and reflects the first light to generate second light having a second wavelength band, wherein a second peak wavelength of the second light is smaller than a first peak wavelength of the first light.
Claims23
A display device comprising:
- a substrate;
- a display layer disposed on the substrate and including a plurality of light emitting areas;
- a code pattern layer disposed on the display layer and including a plurality of position code patterns;
- and
- a reflective layer that receives a first light having a first wavelength band incident from the outside and reflects the first light to generate second light having a second wavelength band,
- wherein a first peak wavelength of the first light is greater than a second peak wavelength of the second light.
A touch sensing system comprising:
- a display device for displaying an image;
- and
- a position input device for outputting first light having a first wavelength band,
- wherein the display device comprises:
- a display layer including a plurality of light emitting areas;
- a code pattern layer disposed on the display layer and including a plurality of position code patterns;
- and
- a reflective layer receiving the first light and reflecting the first light to generate second light having a second wavelength band different from the first wavelength band,
- wherein the position input device senses the second light reflected by the plurality of position code patterns, determines codes of the plurality of position code patterns from the sensed second light, and calculates touch coordinate data by analyzing the codes.
A display device comprising:
- a processor;
- a display panel comprising a plurality of pixels for displaying an image;
- and
- a touch panel comprising a plurality of electrodes comprising a first set of the electrodes for sensing a touch input and a second set of the electrodes including a plurality of code patterns corresponding to a plurality data codes,
- wherein a reflective layer of the display panel is configured to receive a first light having a first wavelength band and reflect the first light off the code patterns to generate second light having a second wavelength band different from the first wavelength band.
