TOUCH SENSITIVE DISPLAY EMPLOYING AN SOI SUBSTRATE AND INTEGRATED SENSING CIRCUITRY

摘要

Methods and apparatus for producing a touch sensitive LCD employing a semiconductor on glass (SiOG) structure provide for: a glass or glass-ceramic substrate; a single crystal semiconductor layer bonded to the glass or glass-ceramic substrate; display circuitry including a plurality of thin-film transistors disposed on the single crystal semiconductor layer and forming a matrix of display pixels; display control circuitry operable to drive the display circuitry to produce viewable images; and sensing circuitry operable to detect electrical characteristic changes in one or more of the single crystal semiconductor layer and the display circuitry, the electrical characteristic changes resulting from user touch events.
