Using current technology, it is possible to design and fabricate performance‐competitive TV‐Sized AMOLED displays. In this paper the system design considerations are described that lead to the selection of the device architecture (including a stacked white OLED‐emitting unit), the backplane technology (an amorphous Si backplane with compensation for TFT degradation), and module design (for long life and low cost). The resulting AMOLED displays will meet performance and lifetime requirements, and will be manufacturing cost‐competitive for TV applications. We fabricated a high‐performance 14″ AMOLED display using an in‐line OLED deposition machine to demonstrate some of these approaches. The chosen OLED technologies are scalable to larger glass substrate sizes compatible with existing a‐Si backplane fabs.
