Abstract
The present invention relates to a touch sensitive LCD flat panel display. The display allows a user to provide input into a computer device by simply touching an LCD display screen with a passive device, such as a finger, stylus, or a ball point pen. The invention includes circuitry which continuously compares the charge times of the liquid crystal elements of the display to a reference value and uses the results of the comparison to determine which elements in the display are currently being touched.
