Optical touch display device |
摘要 |
An optical touch device includes a display panel and at least a light emitting and receiving unit. The display panel includes a transparent substrate having a touch surface and a plurality of side surfaces adjacent to the touch surface. At least one of the side surfaces is a first light incidence surface and at least one of the side surfaces is a first light emitting surface. Each light emitting and receiving unit includes a linear light source and a light sensing component. The linear light source is disposed beside the first light incidence surface and is configured for providing optical signals into the transparent substrate. The light sensing component is disposed beside the first light emitting surface. The light sensing component is configured for receiving the optical signals from the linear light source. The optical touch display device has advantages of low cost.
