Abstract:
An electromechanical device comprises a substrate and an array of pixels (103) arranged on the substrate in rows and columns, a respective pixel having at least one respective light blocking element (202) and at least one electrode for actuating the light blocking element. A plurality of scan line interconnects (110) are formed on the substrate running in a first direction, and enable a plurality of pixels along the first direction to respond to data voltages. A plurality of data interconnects (112) are formed on the substrate running in a second direction perpendicular to the first direction, and provide data voltages to a plurality of pixels along the second direction. For a respective pixel: a first switch (2956) and a second switch (2966) connected in series, are formed on the substrate, and the first switch (2956) and second switch (2966) together connect an energy source to at least one of a light blocking element and the at least one electrode. A data switch (2957) is coupled to a corresponding one of the scan line interconnects (2946) and a corresponding one of the data interconnects (2948) for controlling movement of the light blocking element.
Abstract:
An electromechanical device comprising a substrate and a light blocking element (2304) formed on the substrate and having a first actuator and a second actuator opposing the first actuator for moving the light blocking element between at least a first position and a second position. A flip-flop circuit (2300) is disposed on the substrate and electrically couples the first and second actuators. The flip-flop circuit is configured to maintain an opposite logical state on the first and second actuators, the logical state corresponding to the position of the light blocking element.
Abstract:
A display apparatus comprises a modulator for selectively interacting with light in an optical path to form an image on the display apparatus. A controllable first electrostatic actuator provides a first mechanical support for the modulator, the first mechanical support providing a supportive connection from a first location on the modulator to a surface over which the modulator is supported. A second mechanical support provides a supportive connection from a second location on the modulator to the surface. The first electrostatic actuator drives the modulator in a plane substantially parallel to the surface.
Abstract:
An electromechanical device comprises a substrate; and an array of pixels (103) arranged on the substrate in rows and columns, a respective pixel having a respective light blocking element (202) coupled to a first electrostatic actuator (205) for moving the light blocking element (202) between at least two positions. For a respective pixel: a data voltage interconnect (1602) applies the data voltage to a data switch (1618), and controls a position of the light blocking element (202); and a voltage regulator substantially limits variation in a voltage across the first electrostatic actuator (402) that would otherwise be caused by movement of portions of the actuator (402).
Abstract:
A display apparatus comprises an array of pixels including a transparent substrate, and a plurality of MEMS-based light modulators; and a control matrix disposed on the substrate. The control matrix includes, for a pixel in the array of pixels, i) a writc-enabling interconnect for enabling the pixel to respond to a data voltage, ii) an actuation voltage interconnect for providing a voltage sufficient to actuate the pixel, iii) a first switch for selectively governing the application of the voltage provided by the actuation voltage interconnect to the pixel, and iv) a data voltage interconnect for controlling the first switch. The control matrix thereby regulates the application of the actuation voltage across an actuator included in a respective light modulator, thereby empowering the light modulator to change states to form an image.
