This paper describes the design of a full-color, full-parallax, true holographic display system which will be fabricated as the top layer of an optically flat massively parallel computer. The individual processors of the parallel computer are themselves connected via free-space optical interconnects. The holographic display, which is called the Hoxel Display, utilizes electrostatic fields created by the parallel computer to modulate a thin layer of liquid crystal material, which forms the diffractive display. The computation performed by the embedded processors are used to drive very fine electrodes on the surface of the chip which modulate the liquid crystal. The entire system is fabricated using standard Very Large Scale Integrated (VLSI) circuit technology. There are two major innovations in this work. First, the display will be a low power, low cost, rugged, flat panel holographic display. Second, integrating the processor with the display into a single substrate removes the need for electrical interconnections between the processor and display unit. Each processor/display element contains a photodetector and data extractor circuit, and all information enters the system optically, thus obviating the need for any connections other than power and ground.
