Claim 4:
5. The display panel of claim 4,
wherein the array of pixel driver chips includes a second pixel driver chip connected to the first LED matrix and a third LED matrix;
wherein the third LED matrix includes a plurality of third primary strings of LEDs and a plurality of third redundant strings of LEDs;
wherein the second pixel driver chip includes:
a third group of third output drivers;
a corresponding plurality of third primary driver terminals coupled with the plurality of third primary strings of LEDs in the third LED matrix and a corresponding plurality of third redundant driver terminals coupled with the plurality of third redundant strings of LEDs in the third LED matrix; and
a fourth group of fourth output drivers;
a corresponding plurality of fourth primary driver terminals coupled with the plurality of first primary strings of LEDs in the first LED matrix and a corresponding plurality of fourth redundant driver terminals coupled with the plurality of first redundant strings of LEDs in the first LED matrix,
wherein each third output driver is connected to a corresponding third driver terminal switch to select either a third primary driver terminal or a third redundant driver terminal of the second pixel driver chip, and each fourth output driver is connected to a corresponding fourth driver terminal switch to select either a fourth primary driver terminal or a fourth redundant driver terminal of the second pixel driver chip.
