57.2: Extreme AMOLED Backplanes in a‐Si with Proven Stability

Instability has long been a barrier to the use of a‐Si AMOLED backplanes. We present here the first demonstration of proven stability of a‐Si AMOLED pixels. Over 7000h of stability data is shown for pixel circuits that compensate for threshold‐voltage shift, temperature, and OLED degradation (extreme compensation). This demonstrates that stable AMOLED backplanes are achievable using well‐established and proven a‐Si TFT technology in mainstream use by the flat panel display industry.
