Claim 0:
1. A microLED display comprising:
a light emitting diode (LED) array and driver circuitry,
wherein the light emitting diode (LED) array comprises a first mesa comprising a first stack having a top surface, at least a first LED including a first p-type layer, a first n-type layer and a first color active region and a first tunnel junction on the first LED, the first top surface of the first mesa comprising a second n-type layer on the first tunnel junction; an adjacent mesa comprising a top surface, the first LED, a second LED including the second n-type layer, a second p-type layer, and a second color active region; a second tunnel junction on the second LED of the adjacent mesa, and a third n-type layer on the second tunnel junction of the adjacent mesa; a first trench separating the first mesa and the adjacent mesa; a first metallization layer in the first trench, the first metallization layer extending continuously from and in electrical contact with the first color active region and the second color active region of the adjacent mesa; and second metallization contacts on the second n-type layer of the first mesa and on the top surface of the adjacent mesa; and
wherein the driver circuitry is configured to provide independent voltages to the second metallization contacts.
