Abstract: This disclosure provides systems, methods and apparatus for an all n-type transistor inverter circuit. A circuit can include an input thin film transistor (TFT), a pull-down TFT, a discharge TFT, a first pull-up TFT, a second pull-up TFT, and a floating capacitor. The circuit also can include first and second low-voltage voltage sources and first and second high-voltage voltage sources. The TFTs, the capacitor, and the voltage sources can be coupled such that an output of the circuit is the logical opposite of an input of the circuit. In some implementations, the circuit can exhibit zero DC current in both logic states and can output voltages substantially equal to the voltage output by the first low-voltage voltage source and the second high-voltage voltage source. In some implementations, the circuit can be used to construct D flip-flops, buffers, and controllers for an active matrix electronic display.

Abstract: This disclosure provides systems, methods and apparatus for forming electromechanical systems (EMS) displays where the area of a substrate occupied by a pixel circuit can be reduced if portions of the pixel circuit can be built in three dimensions. In some aspects, certain EMS displays can incorporate structures that are substantially normal to the surface of a substrate. Incorporating circuit components, such as transistors, into such structures, can reduce the area they occupy within the plane of the substrate. In some aspects, the components of a transistor can be fabricated directly into a MEMS anchor that supports a light modulator or a portion of an actuator over the substrate. In some other aspects, the transistor can be fabricated on one or more sidewalls of any MEMS structure.

The display apparatus includes dual-level shutter assemblies. Each dual-level shutter assembly includes front and rear light obstructing levels positioned adjacent to respective front and rear light blocking layers.

Abstract: This disclosure provides systems, methods and apparatus for incorporating tip-gap adjustment features (TGAF) in actuators of shutter assemblies. The TGAF are incorporated into a drive beam of the actuator during the formation of the shutter assembly over a mold. The TGAF are configured such that they develop a mechanical stress or stress gradient. When the shutter assembly is released from the mold, the stress or stress gradient in the TGAF bend the drive beam such that a tip-gap between the drive beam and a load beam of the actuator is reduced. The reduced tip-gap, in turn, reduces an actuation voltage needed to actuate the shutter assembly.
