摘要： A switch panel having a touch plate, light converter, and light analyzer are disclosed. The touch plate includes an optically transparent layer having first and second surfaces, and having an index of refraction greater than that of air. The touch plate conducts light of an excitation wavelength between the first and second surfaces and emits part of that light through the second surface at one of a plurality of emission locations depending on the position at which pressure is applied to the first surface. The light converter is positioned to receive the light emitted through the second surface and generates light having a plurality of distinct location-specific spectra, one of the location-specific spectra corresponding to each of the emission locations. The light analyzer generates a signal indicative of which of the location-specific spectra was generated by the light converter.

摘要： A switch panel having a touch plate, image generator, imaging system and light source is disclosed. The touch plate includes an optically transparent layer having first and second surfaces in which a light signal is trapped by internal reflection. The image generator displays an image that includes a plurality of button positions to a person viewing the touch plate from the first surface. When the user touches the front surface at one of the button positions, light from a multi-LED light source that generates the trapped light signal is caused to escape the touch plate at a point corresponding to the point of contact. The light leaving the touch plate is imaged by the imaging system and used to determine the location of the point of contact. Images taken with different LEDs in the light source are used to make the contact determination to reduce the effects of ambient light.
