SE-4: Compact and High-Optical-Efficiency AR/VR Displays

Shin-Tson Wu

Trustee Chair Professor

College of Optics and Photonics, University of Central Florida 


           

Light-engine and imaging optics jointly determine the performance of augmented-reality (AR) and virtual-reality (VR) displays in terms such as power consumption, form factor, field-of-view, eye box, image quality, contrast ratio, cost, etc. In immersive VR headsets, high-dynamic-range AMLCDs and OLED-on-silicon are currently the two dominant technologies, while high-efficiency pancake lenses and beam-shaping films help to reduce the form factor and power consumption. In optical see-through AR displays, high brightness yet ultracompact liquid-crystal-on-silicon, OLED-on-silicon, LED-on-silicon, MEMS, and laser beam scanners are strong contenders to offer a high ambient contrast ratio for outdoor applications. In terms of optical combiner, geometric optics, diffractive waveguide, achromatic waveguide, and metalens visor are promising candidates for expanding the eye box while keeping a compact and lightweight form factor. To enhance ambient contrast ratio and occlusion, while keeping a low power consumption, a smart dimmer is proven to be effective.

This seminar starts with the ultimate goal for displays (naked-eye 3D), and the demand on realizing such 3D displays, and then introduces colloidal quantum-dot (QD) displays. The next focus is on key technologies for QD to become a display, especially pixel patterning. The recent development of QD patterning, especially photolithography-based patterning, is reviewed. The seminar then introduces the use of electrodeposition, inkjet printing, to achieve high-resolution pixilation and highly reliable quantum-dot light-emitting diodes (QLEDs). More understanding of QLED device physics is also reviewed. A QD microdisplay is demonstrated by integrating QLED onto a silicon backplane. These developments could contribute to the ultimate 2D display panel for lightfield 3D displays.

SE-8: Defect Kinetics and Reduction in Metal-Oxide Thin-Film Transistors 

Man Wong

Professor

 

University of California San Diego  

Defects related to oxygen deficiency play a significant role in determining the characteristics and stability of a metal-oxide thin-film transistor (TFT). It is well known that the population of such defects is sensitive to the temperature, duration, and atmosphere of the annealing process to which a TFT is subjected. The kinetics of defect generation and annihilation have been thoroughly studied and a quantitative model has been developed to relate the turn-on voltage, a measurable electrical parameter, to relevant parameters of the annealing process. Besides thermal processes, fluorination has been reported to be an efficient process for reducing the population of defects, leading to improved TFT characteristics and stability. The conditions of plasma fluorination have been investigated in detail and optimized, resulting in significant improvement in electrical and thermal stability.

Man Wong obtained his BS and MS from Massachusetts Institute of Technology, and his PhD from Stanford University, all in electrical engineering. After working for a few years at the Semiconductor Process and Design Center of Texas Instruments, he joined the Department of Electronic and Computer Engineering at the Hong Kong University of Science and Technology.

SE-14: Thin-Film Transistors for Emerging Applications 

 

Chen Jiang
 

Assistant Professor

Tsinghua University 

This seminar will discuss the fundamentals of oxide and organic thin-film transistors, and their operation in the subthreshold regime for low power applications. Oxide and organic semiconductors have a relatively large bandgap, therefore rendering ultra-low electrical off-state current and good optical transparency. The remarkable features of ultra-low off-state current facilitate deep subthreshold operation, while optical transparency opens up possibilities for multi-modal sensing/modulation in bioelectronics. Subthreshold thin-film transistors have advantages of low power and high gain, which are important for bioelectronic applications; for example, real-time electrophysiologic recording. In addition, the seminar will introduce the novel application of high-channel-count active-matrix neurostimulation, showcasing the expanding role of thin-film transistors beyond traditional applications in display and biosensing.

Chen Jiang is currently an assistant professor with the Department of Electronic Engineering, Tsinghua University. He received a BS in engineering from the Department of Electronic Engineering, Shanghai Jiao Tong University, China, and a PhD in engineering from the University of Cambridge, UK.
