Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
We have developed highly transparent color liquid crystal display (LCD) using newly developed scattering-type liquid crystal, which shows transparent state when voltage is not applied, with field sequential color (FSC) driving method without employing color filter and polarizer. Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back...
Retinal Imaging Laser Eyewear has a miniature laser projector inside the frame which provides the wearer with digital image information through the pupil using the retina as a screen. This compact universal-design eyewear features focus-free and augmented-reality image independent of the wearers' visual acuity and point of focus. This paper describes the background of this technology, the principle...
In this paper, we evaluate the quality of laser projection light field 3D display and propose a comprehensive evaluation of visual fatigue. Subjective questionnaires including the feeling about the quality of two displays and degree of visual fatigue, as well as objective indicators such as Electrocardiograph (ECG) and Electroencephalography (EEG) are recorded during the whole experiment. The results...
In this study, we have discussed how grain sizes of CH3NH3PbI3 perovskites have an impact on the photovoltaic parameters such as a short-circuit current density Jsc, an open-circuit voltage Voc, and hence a power conversion efficiency PCE. As a result, we found that the device with larger grains exhibits the better photovoltaic parameters. The highest PCE was as high as 19.4%, which was obtained for...
To enhance the performance of planar type CH3NH3PbI3 (MAPbI3) perovskite solar cells, we introduced MAPbBr3 because MAPbBr3 exhibits longer charge carrier's diffusion length than the MAPbl3. Although the absorption of MAPbI3−xBrx (x = 0.045) perovskite material is blue-shifted to ∼ 4 nm than that of MAPbl3−xBrx (x = 0), the MAPbl3−xBrx (x = 0.045) solar cell showed ∼ 17.7 % enhanced performance (1...
The manufacturing of solar photovoltaic panels has seen dramatic reductions in costs primarily through business innovations to the extent that the industry is quite laige. The implementation of newer technologies that could further reduce costs are very attractive, especially technologies that can be adapted to continuous printing particularly involving polymer film substrate. The Intense Pulsed Light...
Flat panel displays in automobiles have a long history, starting with simple segment displays for the depiction of HVAC information, radio station or odometer in the instrument panel. The first full color active matrix LCD has been introduced in cockpits more than 20 years ago, in order to show information of navigation systems or an integrated board computers (e.g. phone, climate, infotainment)....
Ultra-thin flexible glass provides all the benefits of glass — thermo-mechanical stability at high temperature, transparency and the best barrier property in a transparent material, while capable of using R2R processing and deliver products that can be flexible. Corning® Willow® Glass is 100–200 μm thick glass that is flexible and is used in a roll-to-roll (R2R) process. In this paper we will discuss...
We summarize the optical properties of lead halide perovskite single crystals, nanocrystals, and solar cells based on perovskite thin films. The complementary information from various spectroscopic and electrical measurements allows us to discuss their photocarrier dynamics with respect to photonic device applications.
This report presents the methods to prepare high quality MAPbI3 film for the p-i-n (inverted) perovskite solar cell. A detailed step-by step to improve the grain size and thickness of MAPbI3 film and the photovoltaic performance of the corresponding cell were discussed. The results demonstrate that the grain size of MAPbI3 film (the film quality) directly related to the efficiency of perovskite solar...
Developing low cost CH3NH3PbI3 solar cell utilising earth abundant carbon as a counter electrode in the hole transport layer free structure is promising for practical applications. Here we demonstrated the solution processed CH3NH3PbI3 solar cells by utilising ambient coated carbon layer as hole transport and counter electrodes. The fabricated devices exhibit the advantages in terms of ambient and...
In order to achieve high-efficiency solar cells, a tandem structure with perovskite and silicon solar cells was introduced and concerned, recently. However, it was difficult to form perovskite top cell on “textured” silicon solar cell due to the in homogeneity layer of perovskite top cells by solution process. In this work, therefore, in order to combine perovskite solar cell as a top cell and “textured”...
A modified Nested-Current-Mirror (NCM) Single-Stage amplifier, for high-resolution, liquid crystal display (LCD) panels, is presented in this paper. The proposed NCM is 12 times faster than the original NCM structure, without any extra power consumption. Slew rate (SR) of the NCM is improved 12 times and DC-gain is also improved 6 dB, while the power consumption, gain-bandwidth product (GBW), noise,...
