10.4L: Late‐News Paper: Joule Heating Induced Lift‐off Technology for Large Area Flexible AMOLED Displays

For large area flexible active matrix organic light emitting diode AMOLED display, we have developed a novel lift off method. This novel technology named as Joule heating induced lift-off JILO uses pulsed electric field for debonding of plastic and the substrate glass. We fabricated the low temperature poly silicon LTPS thin film transistors TFTs on the plastic film. Applying JILO, we can successfully develop flexible TFTs with no damage on transistor performance

9.2: LTPS 5 Mask for 3.5″ WVGA Top Emission AMOLED Displays

The world first LTPS 5 mask top emission active matrix organic light emitting diode AMOLED panel was fabricated by forming the data and the pixel in one step. Employing the coplanar structure of the pixel and the data line, we fabricated the 5 mask 3.5″ WVGA AMOLED successfully.
