Abstract
A control knob assembly primarily for use with devices utilizing flat panel display technology, each assembly having means for manipulating the electronic apparatus by using remote sensing capability to transfer control knob input into a control signal. The assembly is mounted on a bezel, affixed to the front side of the flat panel display and cooperates in conjunction with a plurality of photodiode devices located near the back side of the flat panel display. Photodiodes are located with respect to knob location so as to be able to detect knob adjustment by monitoring a reflected signal that is alternatively disrupted by knob adjustment. The photodiode devices may be infra-red light emitting diode as are well known in the prior art. Circuitry to the photodiode device is used to transmit detected knob adjustment to the appropriate device control circuitry.
