A method of making a display includes providing a display substrate having a plurality of control electrodes in a display area; locating a plurality of chiplets responsive to a controller to provide current to the control electrodes, each chiplet having a separate substrate, at least one pixel connection pad electrically connected to a control electrode, and one or more test light emitters formed in the chiplet responsive to the current provided on the control electrodes to emit light; controlling the chiplets to pass current through one or more of the test light emitters formed in the chiplet to emit light; detecting the light emitted by the test light emitters to determine faulty chiplets or chiplet interconnections; replacing or repairing the faulty chiplets or chiplet interconnections; and forming an organic light emitting diode over the substrate in the display area connected to the control electrodes. |
