1. A display device comprising:
- a display panel comprising;
a first region comprising a plurality of display cells for displaying an image; and
a second region at least partly surrounding the first region, the second region comprising a plurality of light generation cells for generating light, different from the image, to be detected for touch position sensing; and
a pair of cameras located at or near a periphery of the display panel, aligned with respective crossing directions across the display panel, and oriented to detect the light generated by the light generation cells.

28. A method of sensing a touch position of an object on a display device comprising a display panel, a first camera and a second camera, the display panel comprising a first region having a plurality of display cells for displaying an image, a second region at least partly surrounding the first region and comprising a plurality of light generation cells for generating light, different from the image, to be detected for touch position sensing, the method comprising:
-
detecting the generated light with the first camera aligned with a first direction across the display panel; detecting the generated light with the second camera aligned with a second direction across the display panel, the second direction crossing the first direction; and determining the touch position of the object by comparing detection signals of the first and second cameras.

29. A plasma display device comprising:
-
a display panel comprising; a first substrate; a second substrate spaced from and facing the first substrate; and a plurality of barrier ribs between the first and second substrates, the barrier ribs defining a plurality of display cells on a display region for displaying an image and a plurality of light generation cells on a non-display region for generating light that is different from the image; and a pair of cameras located at or near a periphery of the display panel, aligned with respective diagonal directions of the display panel, and oriented to detect the light generated by the light generation cells. - View Dependent Claims (30, 31, 32, 33, 34)
