SYSTEMS AND METHODS FOR MEMS LIGHT MODULATOR ARRAYS WITH REDUCED ACOUSTIC EMISSION

摘要

Systems and methods for a display having an array of pixels, a substrate, and a control matrix formed on the substrate are described. The array of pixels includes mechanical light modulators that can be referred to as micro-electro-mechanical or MEMS light modulators. The MEMS light modulators may be shutter-based light modulators, and an array of apertures may be formed on the substrate corresponding spatially to the shutters in the array of shutter-based light modulators. Each modulator is configured to be driven from a-light-blocking state to a-light-transmissive state through a movement direction. The array of light modulators are arranged to reduce the correlations in movement directions of neighboring pixels, thereby reducing the amplitude of acoustic emissions from the display.

1. A pixel structure comprising:
a substrate having a surface; at least one first actuator; at least one second actuator; at least one third actuator; at least one fourth actuator; a control circuit to control actuation of the at least one first actuator, the at least one second actuator, the at least one third actuator and the at least one fourth actuator; a first light modulator capable of being driven to a light-transmissive state through movement in a first direction in a plane parallel to the surface responsive to actuation of the at least one first actuator; a second light modulator capable of being driven to a light-transmissive state through movement in a second direction in a plane parallel to the surface responsive to actuation of the at least one second actuator; a third light modulator capable of being driven to a light-transmissive state through movement in a third direction in a plane parallel to the surface responsive to actuation of the at least one third actuator; and a fourth light modulator capable of being driven to a light-transmissive state through movement in a fourth direction in a plane parallel to the surface responsive to actuation of the at least one fourth actuator; each of the first direction, the second direction, the third direction and the fourth direction being different.
