Abstract:
An optical touch display includes a display panel, a light source module, and a sensing module. The display panel has a first edge, a second edge, a third edge and a fourth edge. The light source module is disposed beside the first edge and the second edge of the display panel. The light source module is configure for providing a first parallel light and a second parallel light passing through above a display surface of the display panel. The first parallel light passes from the first edge of the display panel through the third edge of the display panel, and the second parallel light passes from the second edge of the display panel through the fourth edge of the display panel. The sensing module is disposed beside the third edge and the fourth edge of the display panel for sensing the first parallel light and the second parallel light. The optical touch display has advantageous of high reliability and low cost.
