Abstract:
1. A method for compensating for a defective light-reflecting device, the method comprising the steps of: providing an array of light-reflecting devices for selectively reflecting light from a light source onto a display screen that has an array of pixels, each of the light-reflecting devices corresponding to one and only one of the pixels of the display screen and having a movable reflective surface for selectively reflecting light from the light source onto the corresponding pixel of the display screen, with a first of the light-reflecting devices corresponding to a first pixel of the display screen and a second of the light-reflecting devices corresponding to a second pixel of the display screen, which is different than the first pixel of the display screen; identifying the first light-reflecting device as being defective; positioning the reflective surface of the second light-reflecting device in a first position such that the light from the light source is reflected by the second light-reflecting device onto a light absorbing material; and positioning the reflective surface of the second light-reflecting device in a second position such that the light from the light source is reflected by the second light-reflecting device onto the first pixel of the display screen that corresponds to the first light-reflecting device.
