Larry J Hornbeck: Bistable DMD addressing circuit and method. Texas Instruments Incorporated, Julie L Schneider, James C Kesterson, Richard L Donaldson, August 25, 1992: US05142405 (344 worldwide citation)

Bidirectional operation of the bistable DMD is preferred over unidirectional operation because it eliminates contrast degradation caused by duty-factor effects and permits lower voltage operation. However, bidirectional addressing requires either two drain lines and two transistors per pixel or one ...
