Linear Light Source Module and Optical Touch Device with the Same |
摘要 |
A linear light source module includes a mirror light guide component and a light emitting component. The mirror light guide component has a light emitting end, a surface having a mirror light reflecting layer formed thereon and a light incidence end. The light emitting component is configured for providing light to the light incidence end. The mirror light guide component is a light guide bar and is configured for converting the light from the first light emitting component into a linear light when the light emitting component is lighted, and the mirror light guide component is a mirror bar and is configured for providing a mirror function when the light emitting component is closed. An optical touch device with the linear light source module can avoid a blind zone and can be used as a dual-touch device or a multi-touch device.
