Abstract

A spatial image display touch device includes an imaging element, a display, an optical film and a sensor unit. The imaging element and the display are retained in a housing and inclined to each other. The display generates an image light passing through the imaging element to form a spatial image. The optical film, composed of a plurality of micro-grids arranged in a matrix, is attached on the display. The sensor unit is mounted in the housing to detect an object appearing at the position wherein the spatial image is displayed. By arranging the optical film in front of the display, only the spatial image is visible and the problem of ghost images is avoided.
