TOUCH SENSOR USING LIGHT CONTROL |
摘要 |
Touch sensing methods and systems implement an optical control layer to direct light through a touch sensor. The optical control layer may be arranged as a structural element of the touch sensor. The structural element incorporating optical control functionality may provide a touch surface of the touch sensor. Processes for manufacturing a light control touch sensor involve providing a structural element that incorporates light control and forming an active touch sensing element on the structural element. |
