Abstract: Display products changed from CRT, PDP to LCD and OLED, and the applications are also diversified from TV, PC monitor and mobiles to digital signage, AR/VR and automobile applications. Recently, there are huge demand on the next-generation displays such as flexible display, micro-LED, QD display and micro-OLED for AR/VR applications. I will explain the display technology history and touch on the current issues on these next-generation displays. Current hot issues for displays are micro-LED and flexible AMOLED. Large area micro-LED displays are a lot demonstrated, but TFT based micro-LED displays are currently focusing for manufacturing of cost-effective displays. On the other hand, flexible AMOLEDs are being manufactured for foldable smartphones and mobile applications. I will discuss these technologies and the future prospect of display technologies for consumer electronics.

Abstract: The main constraint of most mobile electronic devices is not computational power, but rather their energy consumption. These devices rely in fact on rich multi-core platforms with powerful accelerators that could be even exploited further, if it were not to the stringent constraints imposed by batteries. A paradigm that has recently emerged is the so-called "energy quality scalability", which leverages the fact that most functionalities of a mobile device are error-resilient: controlled errors in their operations do not have a dramatic impact on final quality of the outputs, but might allow to simplify the system and therefore save energy. This impact can be fully exploited in mobile systems, where most functionalities are meant for two human senses (sight and hearing) that have limited sensitivity. This talk will present some ideas that are particularly promising and also quite consolidated in the research community, but, in spite of their simplicity and economic sustainability, have not found their way into mobile devices.

Abstract: A display device is an electronic component which shows the image from the electrical signals of the image source such as TV, computer, smart phone, etc. The display is the first impression of a customer in most electronic devices, and the importance of the display is getting higher. Various types of display have been developed, and each display needs different driving scheme for the best performance of the display. Driving scheme is important in terms of the power consumption as well as the display performance. The relationship between display performance and driving scheme will be introduced after a brief review of the driving technologies for various displays. In terms of the performance of the display, driving scheme is much important as well as the fabrication of the display panel itself. The quality of the image strongly depends on the method of the driving and the some fault of the display image can be eliminated by changing the addressing scheme. Various methods for driving various displays will be examined.

Abstract: Thin-film Transistor (TFT) is one of key compoments for flat-panel displays (FPDs). Amorphous silicon (a-Si:H) TFTs have excellent uniformity for large area application; however, field effect mobility and reliability of the TFTs are not sufficient to adress an organic light emitting diode (OLED) display. Excimer laser annealing is used to crystallize amorihous Si into poly-Si (LTPS). Since field effect mobility of LTPS TFT is over 100 cm2/Vs, it is widely used for high-definition and small size FPDs for smartphone. Recently, metal oxide semiconductors, such as InGaZnO (IGZO), have attracted particular attention for TFT applications owing to its high field effect mobility of over 10 cm2/Vs, steep subthreshold swing (S.S.) , extremely low off current, large-area uniformity, and good bias stress stability. In this presentation, recent TFT technologies for active matrix and flexible displays will be discussed including a heterointegration of LTPS and oxide TFTs.

Abstract: Photosensitive thin Si film of new multi-layer structure was designed by calculated simulation for the translation of light spectra, and the film structure was successfully fabricated using semiconductor blue laser diode annealing (BLDA) on glass. By adopting back-reflection layer, drastic increase of light absorption in red and infra-red (IR) region is expected even for 50 nm thickness of Si film. After effective H2 annealing at low temperature after BLDA for the multi-layer structure, functional photo-sensor system with TFT circuits is expected on panel.

Abstract: Advanced two-dimensional (2D) materials have attracted significant interest due to their extraordinary physical and chemical properties over the past decade. Understanding and controlling the growth of novel 2D crystal materials is central for the performance of various applications, spanning from electronics to energy storage. Chemical vapor deposition (CVD) method is a key technology we used to develop exceptional nanomaterials and explore their applications in effective energy storage devices as well as scalable water purification. One of the greatest challenges besetting the development of battery technologies is fast charging, especially within flexible or compact designs. We discuss how the design of low dimensional nanostructure can correlate with the ion transportation efficiency, the activity of electrochemical reaction and energy storage based on chemical transformation. We have also studied the prospects of fast prototyping and scalability for 2D materials based devices.

Abstract: 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.

Abstract: LCoS (Liquid Crystal on Silicon) is a miniaturized reflective active-matrix liquid-crystal display which uses a liquid crystal layer on top of a silicon backplane. It is also referred to as a spatial light modulator. Using CMOS processes, microdisplays with extremely small pixels, high fill factor (pixel aperture ratio) and low fabrication costs are created. LCoS was initially developed for projection televisions, but it now finds applications in various industries, such as automotive, consumer electronics, medical, defense, and several other industries. More recently, the adoption of liquid crystals in Wavelength Selective Switches with the control of light on a pixel-by-pixel basis has been enabled by developments in LCoS backplane technologies derived from projection displays. This presentation highlights our team's study on the LCoS market by product type, applications, design type and architectures.
