ABSTRACT:
In a liquid-crystal display, each pixel is associated with a sensor which detects incoming light projected by a light pen. In response to the detected light, the sensor produces a signal which causes its associated pixel to darken. Thus, as a user moves the light pen along the display, the pen leaves a trail of darkened pixels, analogous to a pen leaving a trail of ink on paper.
