Abstract

A thieno [3,2-b] thiophene-based planar liquid crystal molecule, C12-PTTT, which possesses the characteristics of an organic field-effect transistor (OFET), was synthesised and its mesomorphic properties were studied by polarising optical microscopy and differential scanning calorimetry. A wide temperature range for a highly oriented smectic phase was observed. OFET devices made under various conditions, such as self-assembled monolayer treatment and alignment treatment, and with micro-channel structures, were fabricated to measure the electrical properties. Among different OFET device conditions, the best electric carrier mobility for C12-PTTT was 0.038 cm2 V−1 s−1. [ABSTRACT FROM AUTHOR]

Abstract

Color sequential transmissive and reflective projection displays using a vertical field switching (VFS) polymer-stabilized blue phase liquid crystal (BPLC) are proposed. The VFS-BPLC exhibits submillisecond response time which is useful for suppressing color breakup, hysteresis-free for accurate grayscale control, high optical efficiency, and low operation voltage.

Abstract

The unplugged electronic display were fabricated and investigated in this study. The electro phoretic display (EPD) and solar cell device were laminated as an ultra thin structure, leading to a flexible, light and unbroken characteristics. Also, surface engineering for dust-proof and water-proof was performed for product application. Furthermore, the electricity generated by solar cells can support the operation of EPD device by maximum power point tracking (MPPT) technology. [ABSTRACT FROM AUTHOR]

Abstract

A 6-inch rollable active-matrix electrophoretic display driven by organic thin-film transistor is demonstrated by using solution and photolithography processes. All process temperature are kept below 120 degree C. Pixel OTFT devices exhibit an average mobility of 0.6 cm2/Vs and good reliability. The rollable EPD prototype has thin (125um) and light (14g) features. The minimum rolling diameter can reach 25 mm. [ABSTRACT FROM AUTHOR]

23. Effects of Ambient Atmosphere on Electrical Characteristics of Al2O3Passivated InGaZnO Thin Film Transistors during Positive-Bias-Temperature-Stress Operation

Author

Huang, Sheng-Yao, Chang, Ting-Chang, Chen, Min-Chen, Chen, Shih-Ching, Tsai, Chih-Tsung, Hung, Ming-Chin, Tu, Chun-Hao, Chen, Chia-Hsiang, Chang, Jiun- Jye, and Liau, Wei-Lung

Abstract

This study investigates the effects of ambient atmosphere on electrical characteristics of Al2O3passivated InGaZnO thin film transistors during positive bias temperature stress. Under H2O vapor environment, the Al2O3passivated device exhibited stable electrical behaviors (ΔVth< 0.5 V), while the unpassivated device showed an apparent hump effect in the transfer curves under bias stress. The hump phenomenon was attributed to the absorption of the H2O molecule which can serve as a donor to develop a conductive back channel. The experiment results suggest that Al2O3is an effective passivation layer to suppress water vapor absorption in the InGaZnO back channel.
