Abstract
A multi-touch sensing apparatus using a rear view camera of an array type is provided. The multi-touch sensing apparatus may include a display panel to display an image, a sensing light source to emit light to sense a touch image which is generated by an object and displayed on a back side of the display panel, and a camera to divide and sense the touch image. The camera may be arranged in an edge of a lower side of the multi-touch sensing apparatus, or a mirror to reflect the touch image may be included in the multi-touch sensing apparatus.
Claims5
A multi-touch sensing apparatus, comprising:
- a display panel arranged on an upper side of the multi-touch sensing apparatus, and configured to display an output image;
- a sensing light source configured to emit a first light to sense a touch image generated by touch of an object on a front side of the display panel and displayed on a back side of the display panel;
- a mirror configured to reflect the touch image;
- a camera configured to sense the reflected touch image;
- and
- a backlight configured to emit a second light to display the output image on the display panel,
- wherein the mirror reflects the second light toward the display panel and decreases a distance between the camera and the back side of the display panel by being disposed on an edge of a lower side of the multi-touch sensing apparatus,
- wherein the camera is arranged under the display panel and inside the multi-touch sensing apparatus, and
- wherein the camera is configured to divide the touch image reflected by the mirror and sense one of the divided touch images.
