| 英文摘要 | Touch screen sensor systems that incorporate VCSELs or VCSEL arrays to provide illumination beams for sensing the position of objects such as a finger or stylus in a two dimensional space is provided. Normally the touch sensor is used with a display screen so that objects in the display screen are identified by positioning a finger or stylus at the object's position. The invention describes improved illumination methods using VCSELs that realize higher resolution in position sensing. VCSELs can also be integrated with detectors on a common substrate which provides both illumination and detection functions for the touch sensor system. Different methods to suitably couple light from VCSEL arrays directly, or through guided light paths such as fibers and waveguide arrays are provided to configure a touch sensor in different applications. |
