INDICATOR WITH TOUCH DETECTION NOT PATTERNIZED |
摘要 |
<p>A display device locates a touch anywhere on a conductive display faceplate by measuring plural electrical impedances of the faceplate conductive coating. The impedances are at electrodes located on different edges of the faceplate. A touch locating circuit determines the location of a touch using known pulsed signals and, in another embodiment, using a tuned measuring signal.</p> |
