We present organic thin film transistors (OTFT) with leakage currents below 10 -17 A/µm and compare them to existing TFT technologies. The impact of low leakage on the dynamic range of an optical sensor was modelled to demonstrate its benefit to the performance of 500ppi device.

A well‐known method of increasing the contrast of an LCD is to use a dual cell. FlexEnable's low temperature organic TFT process allows us to work directly with polarisers as substrates. This reduces the gap between the cells to previously unreachable levels, allowing pixel level dimming and OLED‐like contrast from a simpler stack.
