Abstract: There is of increasing interest for thin-film transistor (TFT) which can be a basic device for displays and sensors. A big advantage of TFT is that it can be manufactured on any substrate including flexible and stretchable ones. For example, the substrate for display changes from glass to polyimide, and the glass which was used for display manufacturing for many tens of years will change into plastic within in 10 years. I will discuss the display and sensor applications of TFTs and will presents the recent results we have developed for sensor and flexible displays. Finally, I will discuss the future prospect of TFT applications on plastic substrates.

Abstract: The main constraint of most personal consumer electronic devices is not computational power, but rather their energy consumption. The potentiality of these devices could be even pushed further, if it were not to the stringent constraints imposed by batteries.
In the last 20 years there has been a continuous effort in reducing the power demand of those devices: state-of-the-art components have reached impressive energy efficiency figures. However, focusing on how the available energy is consumed is only one part of the picture; Many consumer devices are battery-operated, and the way this inite amount of energy is extracted from the battery, distributed, and converted is an often overlooked issue.
In this talk we will show how focusing only one how the energy is consumed will severely underestimate the actual usability of consumer devices, and propose solutions for a smart management of energy by carefully analyzing also its storage, distribution, and conversion.

Abstract: The water level sensor was developed with single transistor on printed circuit board. The cost was reduced by one transistor operation of the sensor while the sensitivity keeps high by the bootstrapped sensor circuit. After patterned printed circuit board preparation, one transistor was attached by soldering. The printed circuit board was enclosed in a package for dipping into the water. The inside was filled with epoxy resin. After applying the pulses to the input pad, the outputs were measured at the output pad. The output signal was increased when the tank was empty and decreased when the tank was filled by water. Some consumer electronics are using the water tank which needs the sensor to check the height of the water. The developed water level sensor is useful for those applications.

Abstract: An In–Ga–ZnO thin-film transistor (IGZO TFT) with a heterojunction channel was demonstrated to enhance field effect mobility (mFE) and positive bias stress stability (PBTS). For achieving a hetero-junction channel, a stacked film of high-In composition IGZO layer (IGZO-high-In) on typical compositions IGZO layer (IGZO-111) was employed to form the type-Ⅱ energy band diagram which possess a conduction band discontinuity (DEc) at a hetero interface. The mFE of the IGZO TFT increased to 23.7 cm2/Vs which is twice as high as a conventional IGZO TFT. Carrier transport mechanism in the heterojuction IGZO channel will be discussed based on the experimental and device simulation results.

Abstract: We proposed a holographic retina display for augmented reality. We use a single phase-only spatial light modulator and a double phase method to directly modulate the light at multiple planes inside the eye. The complex amplitude of hologram is transformed to pure phase value based on double-phase method. To suppress noises and higher order diffractions, we introduced a 4-f system with a filter at the frequency plane. A blazing grating is proposed to separate the complex amplitude on the frequency plane. Due to the complex modulation, the speckle noise is reduced. Both computer simulation and optical experiment have been conducted to verify the effectiveness of the method. We also presented a hologram calculation method based on light field capturing, which is efficient for rendering 3D natural scene. The results indicate that this method can effectively reduce the speckle in the reconstruction in 3D holographic display. By changing the focal length of the eye, images at different depth planes are sharply projected onto the retina, which solve the accommodation and convergence conflict problem for augmented display.

Solar energy is one of the most efficient renewable energy sources that can be harvested at minimum cost. The growth of solar photovoltaic system implemented on rooftop or solar farm to generate power is significant and dominated by China, United States, Japan and India. Therefore the availability of cost effective solar cell is essential to support the solar PV demand. Meanwhile, in recent years, commercially available silicon and thin film solar cell dominate solar cell market due to its high efficiency and stability. However new type of solar cell such as organic solar cell, perovskite solar cell and dye-sensitized solar cells (DSSCs) have been intensively studied and developed. DSSCs have attracted considerable attention due to its advantages such as of low production cost, non-toxic material and simple fabrication process. However, more effort is needed to enhance the DSSC overall efficiency toward commercialization. DSSC highest efficiency reported by Sharp Corporation in 2016 was 11.9% using Black Dye as synthesizer and Cobalt electrolyte as hole transport material. In this session, DSSC efficiency enhancement utilizing AgNP/TiO2 plasmonic nanocomposite will be presented. The nanocomposite with different amount of AgNP were prepared by chemical reduction method using AgNO3 as precursor. The incorporation of AgNP onto the TiO2 has considerably improved the absorption in the visible region of solar spectrum due to the surface plasmon effect by silver nanoparticles. Then a method of incorporating carbon quantum dots (CQD) into TiO2 has also been studied in which the CQD can enhance the visible light absorption in DSSC. Both techniques shows significant improvement in light absorption which reflects to the DSSCs efficiency.
