Abstract:
1. A reflective mirror, adapted to be used in an optical touch device defined with a sensing area, the optical touch device includes a light source module to provide light to the sensing area, the reflective mirror comprising: a reflective film comprising a first connection surface and a plurality of reflection structures opposite to the first connection surface, the reflection structures adjacent to the light source module, each reflection structure protruding away from the first connection surface, each reflection structure including a light reflection region and a light penetration region, the light reflection region alternatively arranged with the light penetration region, each reflection structure including at least a reflective surface connected to the light penetration region, and the light reflection region including the reflective surface; a light-transmitting base comprising a light penetration surface and a second connection surface opposite to the light penetration surface; and a light-transmitting adhesive layer disposed between the reflective film and the light-transmitting base and connected to the first connection surface and the second connection surface; wherein the light provided by the light source module is capable of passing through the light penetration region and thereby emitted to the light sensing area.
