摘要:
A coordinate locating device capable of locating the coordinates of two or more objects is provided for a display apparatus. The coordinate locating device includes a first detector arranged together with a first light source at a first corner of the coordinate locating device, a second detector arranged together with a second light source at a second corner of the coordinate locating device, at least one reflector configured to reflect light from the first and second light sources, and a mirror arranged on a first edge of the coordinate locating device, configured to reflect mirrored images of two or more objects intruding the coordinate locating device, wherein the first and second detectors detect real images of the two or more objects, and at least one of the first and second detectors further detects the mirrored images of the two or more objects reflected by the mirror.
