Abstract Flexible active matrix TFT array backplanes were fabricated on 51 μm thick polyimide foil (Kapton®E) substrates. Expected applications include low cost flexible lightweight displays using electrophoretic, OLED, and PDLC displays. TFT performance of the Kapton backplane is nearly identically to the same structure fabricated on a glass substrate. Measurement of the transfer and output characteristics while the sample was bent at an inward radius of curvature of 2.5 cm indicate no loss in TFT performance.
