A repair path is established between a sub-pixel with a defective drive transistor and another sub-pixel with an operable drive transistor to connect storage capacitors in the two sub-pixels in parallel. Another repair path is established to operate a light emitting device by the operable drive transistor of the second sub-pixel. Terminals of the storage capacitors in the two pixels are connected to a gate of the operable drive transistor. The voltage at the terminals of the storage capacitors are maintained above the threshold voltage of the operable drive transistor is switched on for a longer time due to the combined capacitance of the two storage capacitance. Hence, the sub-pixel with the defective drive transistor and the other sub-pixel of the operable drive transistor remain turned on for a longer time. Hence, despite providing a lower level of current to each of the light emitting devices in the two sub-pixels, the intensity of light produced remains relatively high due to increased turn on time of the operable drive transistor.
