Micro-optical components for Light Field AR/VR Display Application
Yi-Pai Huang

Depth, resolution, and field of view(FoV) are always the key factors in light field technology. With optimized micro-optical component, the three factors can be fully compensated. Those micro-optical devices can be passive or electrically driven. In this presentation, we will focus on discussing various Liquid Crystal devices which can change the focal length, scan and shift the image position, which can also result in high-resolution image. Additionally, the optimized free-form optical lens array can further enlarge the FoV of AR/VR glass. Finally, the new application of using VR display for bio-medical application will be discussed.

Po-Han Tsai Award Candidate Using a Scattering Film to Eliminate Reflective Diffraction while Keeping Image Sharpness for OLED Displays
Po-Han Tsai;Chi-Chieh Wu;Zong Qin;Yi-Pai Huang

To eliminate reflective diffraction in OLED display, a scattering film whose threshold haze and transmittance is calculated is applied based on contrast sensitivity function (CSF). Also, the maximum distance between the scattering film and OLED that can make image quality beyond certain MTF criterion is determined depending on different resolutions.

Fang Yu Liu Award Candidate A transparent display with high image quality composed of organic light-emitting diode and cholesteric liquid crystal light shutter
Fang Yu Liu

Transparent display is expected to be a next generation technology which has been sufficiently discussed in recent year. However, the image quality of the transparent active matrix organic light-emitting diode. In this work, the concept of high-image-quality transparent display based on AMOLED with a desirable liquid crystal shutter is demonstrated.

T. JAIRAM Award Candidate Synthesis, Photophysical and Electrochemical Studies of di-triphenylamine-1, 10 Phenontroline based fluorophore for Organic Light Emitting Diodes
T. JAIRAM;Sivakumar Vaidyanathan

Abstract: Organic Light Emitting Diodes are gaining interest due to their significant contribution in the field of lighting and displays technology. In the present study, a new di-triphenylamine-1, 10 Phenontroline based fluorophore have been designed and synthesized. A detailed photophysical and electrochemical properties were systematically studied.

Jung-Chun Tseng Award Candidate Composite polythiophene field effect transistors with multifunctional graphene nanostructures
Jung-Chun Tseng

We investigate multifunctional graphene nanostructures as carrier mobility enablers and moisture and air barrier films for organic-based polythiophene FET. The carrier mobility of Gr-P3HT FET was higher than pristine P3HT device mobility ten times. Gr-P3HT FET laminated with graphene passivation layers exhibit significantly superior and prolonged performances over 1350 hours.

Mao Chou Tai Influence of floating ITO Effect on Reliability in a-IGZO TFT
Mao Chou Tai;Ting-Chang Chang;Hsiao-Cheng Chiang;Yu-Ching Tsao;Yu-Chieh Chien

In this work, we reported that a dual gate TFT when the top gate ITO is floating could suppress the threshold voltage shift of TFTs after negative bias temperature stress. TCAD simulations of the electrostatic potential and evidence of capacitance coupling has been further discussed.
