230 DPI High Resolution AMPLED Display on Flexible Metal Foils with Integrated Row Drivers

This paper presents a 230 dpi Active Matrix Polymer Light Emitting Diode (AMPLED) display on flexible stainless steel substrates fabricated with laser annealed poly-silicon TFT technology. The high resolution display is based on the standard 2 TFT pixel circuitry to form a full VGA array. Polysilicon TFT based shift registers for integrated row driving are also demonstrated. Display fabrication is compatible with standard polysilicon TFT CMOS processing temperatures and conditions. This paper discusses backplane fabrication, PLED deposition and display encapsulation; all performed in-house.
