1. A display apparatus comprising:
- an array of pixels arranged in rows and columns including a substrate having a plurality of apertures, and a plurality of shutters configured for transverse motion relative to the substrate corresponding to the plurality of apertures; and
a control matrix disposed on the substrate including, a common electrical connection among a set of pixels, the set of pixels including pixels in at least two of the columns and in at least two of the rows, a data voltage interconnect corresponding to one of the columns, and a switch corresponding to one of the pixels for controlling actuation of a corresponding shutter in response to a voltage applied by the data voltage interconnect.

12. A method of forming an image on a display, comprising:
-
selecting a first scan-line of the display, wherein the scan line includes a plurality of pixels;
for at least a first pixel of the plurality of pixels in the selected scan line, selectively regulating a voltage across a first actuator, thereby enabling the first actuator to move a corresponding first shutter relative to a first aperture defined in a substrate;
selecting a second scan-line of the display including a second plurality of pixels;
for at least a second pixel of the second plurality of pixels in the selected second scan line, selectively regulating a voltage across a second actuator, thereby enabling the second actuator to move a corresponding second shutter relative to a second aperture defined in the substrate;
applying a global actuation voltage to a global actuation interconnect shared among at least two pixels in the first scan line and at least two pixels in the second scan line, thereby actuating the first and second enabled actuators; and
directing light towards the substrate to form an image. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
