Circuits for controlling display apparatus
First Claim
Patent Images
1. A direct view display apparatus comprising:
- a transparent substrate;
an array of pixels formed on the substrate including, for each pixel, a MEMS-based light modulator including a light modulator comprising a first electrostatic actuator for changing the state of the light modulator; and
a control matrix connected to the substrate including, for a pixel, a write-enabling interconnect for enabling the pixel to respond to a data voltage and a data voltage interconnect for applying the data voltage to a data switch, thereby controlling the state of the light modulator of the pixel;
and a voltage regulator for substantially limiting variation in a voltage applied across the actuator during actuation that would otherwise be caused by movement of portions of the actuator.

38. A direct-view display apparatus comprising:
-
a transparent substrate, an array of pixels organized into rows and columns, wherein the rows are divided into at least two sets of rows, each respective row in a set of rows being associated with a corresponding row in the other sets of rows, collectively forming groups of rows, the array including for each pixel, light modulator formed on the substrate and including a first actuator for controlling the state of the light modulator; and a control matrix connected to the substrate including; for each group of associated rows, an electrical connection shared among the pixels of the associated rows, thereby enabling the group of associated rows to be actuated to an addressed state at substantially the same time. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46)
