Claim 0:
1. A method of compensating at least one pixel for an image in a display, comprising the steps of:
(a) storing a pixel map for a display area of the display, the pixel map having a plurality of non-degraded pixels and at least one degraded pixel;
(b) projecting at least one fixed pattern on the display area;
(c) determining a number (NO) of non-degraded pixels required to turn on a sensing system, wherein the number of non-degraded pixels have a luminescence beyond a threshold luminescence sufficient to turn the sensing system on;
(d) setting a count value (i) to zero;
(e) generating a symbol S by energizing a number of degraded pixels equal to i;
(f) measuring a luminescence output of the sensing system to determine whether the sensing system is on;
(g) if the sensing system is not turned on at step (f), adding one to i, and re-generating S by energizing one additional degraded pixel;
(h) if the sensing system turns on at step (f), determining a degradation level based on NO and S;
(i) updating the pixel map based on a current value of S and the degradation level; and
(j) generating image data for forming a compensated image in the display.
