In this work, we demonstrated high-performance transparent flexible amorphous indium-gallium-zinc-oxide thin-film transistors on ultrathin polyimide substrates. The threshold voltage, saturation mobility, subthreshold swing, and current on/off ratio of the TFT are 0.88 V, 15.96 cm^2/Vs, 0.542 V/dec and 1.15 × 10^9. It also exhibits good stability against gate-bias stress.

 

We demonstrate p-channel solution-processed nanocomposite field effect transistors based on conjugated 6,13-bis(triisopropylsilylethinyl)pentacene or poly(3-octylthiophene-2,5-diyl) on an ordered network of germanium nanowires. With an appropriate loading of germanium nanowires into the active channel, nanocomposite transistors show an enhancement of more than a factor of 10 over pristine devices.

 

This study reports the optically and electrically controllable electro-optical characteristics of dichroic dyes-doped cholesteric LCs, including driving voltage, driving frequency, photo-isomerization, response time, polarizer-free and variations of structures. This light shutter has advantages of optically controllable steady state, electrically controllable absorptive state and high contrast ratio.

 

This study demonstrates a stable and defect-free uniform lying helix alignment by a cholesteric liquid crystal doped with bent-shaped liquid crystal dimer, CB7CB. The frequency-dependent flexoelectric responses can be observed by means of transmission spectra with crossed polarizers.

 

We investigate the effect of weight percent of the reactive monomer (RM257) dispersed in cholesteric liquid crystal (CLC) on the quality of polymer-network CLC templates. By analyzing electro-optical and textural properties one can determine the robustness of the polymer template, and thus, the performance of a refilled sample.

 

The optical axis of the uniformly lying helix state and uniformity of the cholesteric liquid crystal cells with various rubbing angles were investigated. The substrate was rubbed with different rubbing angles, and experimental results suggest the uniformity in the ULH state can be controlled by the rubbing angle.

 

A new AR glass based on time-multiplex method was proposed. To extend display depth range, light field technology is introduced. In this paper, both diffraction issue and image quality are simulated and verified. Due to simple structure, FoV could be expanded further by combining with curve optical components in future.
