Control circuit for stacked oled device

A method of driving a plurality of control circuits, each controlling two organic light-emitting diodes, comprising the steps of:

• a) providing first and second electrodes and a first OLED formed there-between for each of the plurality of control circuits, wherein the first and second electrodes are independently controlled from each other;
• b) providing a third electrode and a second OLED formed between the third electrode and the second electrode, wherein the third electrode is connected in common with the third electrode from another OLED control circuit and independently controlled from the first and second electrode;
• c) providing a bypass transistor connected to the third electrode and second electrode and responsive to a bypass control signal;
• and
• d) driving the first, second, and third electrodes with the control circuits and bypass control signal to control amount of current passing through the first and second OLEDs.

A method of making a plurality of organic light-emitting diodes and control circuits, comprising the steps of:

• e) providing a substrate;
• f) forming a thin-film bypass transistor over the substrate;
• c) forming a first patterned electrode over the substrate;
• d) forming a first OLED over the first electrode;
• e) forming a second patterned electrode over the substrate and connected to the bypass transistor;
• f) forming a second OLED over the second electrode;
• and
• g) forming an unpatterned electrode over the second OLED and connected to the bypass transistor.
