Embodiment Construction

[0048] figure 1 A is an isometric view of the display device 100 according to the exemplary embodiment of the present invention. The display device 100 includes a plurality of light modulators, in particular, a plurality of shutter assemblies 102a-102d (collectively "shutter assemblies 102") arranged in rows and columns. In general, a shutter assembly 102 has two states, open and closed (although partial opening may be used to impart gray scale). The shutter assemblies 102a and 102d are in an open state, allowing light to pass through. The shutter assemblies 102b and 102c are in a closed state, blocking the passage of light. By selectively setting the state of the shutter assemblies 102a-102d, if illuminated by the lamp 105, an image 104, either projected or backlit, can be formed using the display device 100. In another embodiment, device 100 may form an image by reflecting ambient light originating from the front of the device. In display device 100 , each shutter assem...

Abstract

The invention relates to MEMS-based display devices. In particular, the display devices may include actuators having two mechanically compliant electrodes. In addition, bi-stable shutter assemblies and means for supporting shutters in shutter assemblies are disclosed inclusion in the display devices.

Description

[0001] Information about divisional applications [0002] This application is a divisional application, the filing date of the original application is February 23, 2006, the application number is 200680005822.2 (international application number PCT / US2006 / 006552), and the name is "method and device for operating a display". technical field [0003] The present invention relates generally to the field of video displays and in particular to mechanically actuated display devices. Background technique [0004] Displays constructed with mechanical light modulators are an attractive alternative to displays based on liquid crystal technology. Mechanical light modulators are fast enough to display video content with good viewing angles and a wide range of colors and grayscales. Mechanical light modulators have been used successfully in projection display applications. Backlit displays using mechanical light modulators, however, have not yet exhibited an attractive enough combinati...
