Abstract
A display apparatus including a display, and a detector which is coupled to the display. The touch detector is to detect a touch input when light passing through a touch area on the display is blocked. The touch detector includes a cover member covering the display, and the cover member includes at least one curved surface formed to guide light passing through the touch area.
Claims14
A display apparatus comprising:
- a display having a display surface;
- and
- a touch detector including cover glass coupled with the display surface to detect a touch input when light passing through a touch area in a front side of the display surface is blocked,
- wherein a front surface of the cover glass includes a concave curvature to guide the light passing through the touch area, the concave curvature being curved along a first direction and a second direction which are orthogonal to each other.
