Claim 0:
1. A display panel comprising:
an array of pixel driver chips connected to a corresponding array of LED matrices, the array of LED matrices including a first LED matrix, and the array of pixel driver chips including a first pixel driver chip connected to the first LED matrix;
wherein the first LED matrix includes a plurality of first primary strings of LEDs and a plurality of first redundant strings of LEDs;
wherein the first pixel driver chip includes a corresponding plurality of first primary driver terminals coupled with the plurality of first primary strings of LEDs and a corresponding plurality of first redundant driver terminals coupled with the plurality of first redundant strings of LEDs; and
wherein the first pixel driver chip includes a first portion of pixel driver circuitry comprising:
a first group of first output drivers; and
a first group of first driver terminal switches;
wherein each first output driver is connected to a corresponding first driver terminal switch that switches between a first primary driver terminal and a first redundant driver terminal to select either the first primary driver terminal or the first redundant driver terminal of the first pixel driver chip.
