Abstract
A controller including a chip package coupled with a light-based touch screen, emitter driver circuitry inside the chip package for selectively activating photoemitters that are outside of the chip package, detector driver circuitry inside the chip package for selectively activating photo detectors that are outside of the chip package, detector signal processing circuitry for generating detection signals representing amounts of light detected on the photo detectors, signal conducting pins for connecting the photoemitters to the emitter driver circuitry, signal conducting pins for connecting the photo detectors to the detector driver circuitry and to the detector signal processing circuitry, controller circuitry inside the chip package for controlling the emitter driver circuitry and the detector driver circuitry, and at least one input/output pin for outputting the detection signals to a host processor, for the host processor to identify one or more locations on the touch screen that are being touched.
