Abstract
The invention is directed towards an apparatus and method for masking display element defects in a display device. In one embodiment, the invention includes a display device with display elements disposed on a display surface, a translation unit that is coupled to the display device to impart periodic motion to the display surface, a display signal source capable of providing input signals to the display device, and a control unit coupled to the translation unit and the signal source to direct the movement of the display device and the signal source to correspondingly shift the display signals, which when displayed, conceal display element defects while presenting a stable image to a stationary viewer.
Claims21
An apparatus for masking defects in a visual display, comprising:
- a visual display unit having a plurality of display elements;
- a translation unit coupled to the visual display unit that is structured to impart motion to the display unit;
- and
- a control unit coupled to the translation unit and the display device that is structured to receive image signals from an image signal source and capable of exchanging signals with the translation unit and the display unit to controllably direct the movement of the display unit and to compensatingly shift the image signals, the signals being maintained at a fixed signal level as the image signals are shifted, the shifted signals concealing display element defects on the display surface.
A method for concealing a defective display element in a visual display surface, comprising:
- directing an image signal having a signal magnitude onto a first display element positioned in a first display location, the first display element being at least partially defective;
- translating a second display element into the first display location;
- directing the image signal onto the second display element while the second display element is in the first location while maintaining the signal magnitude.
