APIX, Inova Semiconductors Pixel Link for medium-size displays, was developed with the aim of eliminating the limitation of distance between the control computer and the display. The specifications for this were provided by the automotive industry's catalog of requirements.
The result is a significant reduction in radiated noise, cable diameter and cost. APIX requires only a single twisted pair cable for the transmission of video and control information. Alternatively, a return channel can be used with another twisted pair wire pair to implement a full duplex capable communication interface.
