We have developed an AMOLED panel using hybrid backplane technology with IGZO and LTPS. This panel contains both Gate-on-Array and pixel circuits with high reliability TFTs. The panel can operate between 1 and 120 Hz. We operated at 60^oC for 1,000 hours and it remain operational without any display problem.
