Abstract: Systems and methods for a digital pixel circuit for liquid crystal displays are provided. The design includes a dual-voltage pixel design, a two-transistor level-shift circuit design, self-adjusting transistor bias circuitry; and an optional on-chip test-array to determine die-specific design-center values for critical transistor leakage and threshold parameters. Level shift design simplicity, small pixel pitch, and applicability for small display applications such as microdisplays, are among the various benefits and advantages obtained.
