Liquid Crystal Display Panel.

The objective of this program is to demonstrate the feasibility of developing an effective x-y addressed liquid crystal display by fabricating a three-inch square flat dynamic scattering device incorporating all addressing and drive circuitry for the display of alphanumeric and vector-graphical information at a resolution of 30 lines per inch. The reflective display will be built directly on a silicon substrate containing an MOS random access memory with interface drivers. To eliminate chip-to-chip interconnections inside the display, the substrate will be a mosaic of four 1.7-inch square integrated circuit chips with exceptionally low circuit density. A partial redesign of the MOS circuit layout to facilitate photomask generation for these very large devices by reticle composition has been completed. A mechanical prototype display was built.
