High‐mobility solution‐processed organic thin‐film transistor array for active‐matrix color liquid‐crystal displays

Abstract

Abstract— A solution‐processed organic thin‐film‐transistor array to drive a 5‐in.‐diagonal liquid‐crystal display has been fabricated, where semiconductor films, a gate dielectric film, and passivation films have all been formed using solution processes. A field‐effect mobility of 1.6 cm2/V‐sec, which is among the highest for solution‐processed organic thin‐film transistors ever reported, was obtained. This result is due to semiconductor material with large‐grain‐sized pentacene crystals formed from a solution and adoption of three‐layered passivation films that minimize the performance degradation of organic thin‐film transistors.

“…Their TN-LCD with all solution processed OTFT backplane would have been compatible with a plastic substrate as the process temperature was kept below 150 C after the pentacene deposition [4].…”

“…Though not on glass, Hitachi manufactured a 5” colour QVGA LCD in 2008 with Organic pentacene TFTs demonstrating a mobility of 1.6cm 2 /Vs, amongst the highest reported at the time. Their TN‐LCD with all solution processed OTFT backplane would have been compatible with a plastic substrate as the process temperature was kept below 150°C after the pentacene deposition .…”

Non-volatile transistor memory fabricated using DNA and eliminating influence of mobile ions on electric properties

“…Printing processes are attractive for the fabrication of electronic devices such as radio-frequency identification (RFID) tags, 1 sensors, 2 and active matrix displays 3 on a plastic substrate. [4][5][6] Since organic compounds can be dissolved in a solvent, electric materials are promising candidates for use as inks in the printing process. [7][8][9][10] Further, since biopolymers, such as deoxyribonucleic acid (DNA), proteins, and polysaccharides, have a highly ordered structure, functional molecules can be oriented along the ordered structure.…”

Influence of Substitution Group of the Side Chain of Polypeptide on the Morphology and its Hysteresis Property as a Ferroelectric Memory Device

“…Organic materials have been attracting significant interest for their potential use as inks in low-cost printable electronics device such as flexible displays [1][2][3], electronic papers [4][5][6][7], RFID tags [8], and sensors [9]. Printable nonvolatile memories have high applicability in electric devices, but promising techniques for the fabrication of these memories have not been developed thus far.…”
