Three dimensional position sensing apparatus and method for a display device |
摘要 |
A position sensing device for a display device includes an oscillator, a first and second electrode pair, a transparent conductive layer positioned on a display of the display device, first and second differential amplifiers, an amplifier and a processor. The first differential amplifier provides a first signal indicative of distance of the first electrode pair from the second body part of the operator in an x-direction. The output of the second differential amplifier provides a second signal indicative of distance of the second electrode pair from the second body part of the operator in a y-direction. The output of the amplifier provides a third signal indicative of distance of the transparent conductive layer from the second body part of the operator in a z-direction. The processor is operable to generate a three dimensional distance signal based on the output of the differential amplifiers and amplifier.
