Real-time compensation for blue shift of electromechanical systems display devices

摘要

This disclosure provides systems, methods, and apparatus related to electromechanical systems display devices. In one aspect, an apparatus includes a display assembly, a sensor, and a processor. The display assembly may include an array of electromechanical systems display devices. The sensor may be configured to provide a signal indicative of an illumination angle, a viewing angle, or both, with respect to a line perpendicular to the display assembly. The processor may be configured to receive the signal from the sensor, to determine the illumination angle and/or viewing angle, and to process image data to compensate for the determined illumination angle and/or viewing angle. In one implementation, the image data is processed to compensate for a shift in a wavelength of light reflected from at least one of the electromechanical systems display devices that would have occurred as a result of a non-normal illumination and/or viewing angle.

主权项

1. An apparatus for displaying an image comprising:
a display assembly including an array of electromechanical systems display devices; a sensor configured to provide a first signal, the sensor being oriented in a sensor plane having a first angle relative to a plane of the display assembly; and a processor configured to:
communicate with the display assembly and the sensor, the processor configured to receive the first signal;determine an illumination angle with respect to a line perpendicular to the display assembly indicated by the first signal; andprocess image data to compensate the image for the determined illumination angle.
