    In this letter, a new backlight dimming technique that considers perceptual image quality based on a structural similarity (SSIM) metric is proposed. Conventional algorithms cannot accurately control the optimal trade-off between image quality and power consumption; image quality is therefore degraded in some images. In contrast, the proposed algorithm calculates the allowable target error based o... View full abstract»

    In this letter, a new subpixel rendering algorithm using the hue-saturation-intensity (HSI)-based color error analysis is proposed for matrix display devices. The proposed method converts an RGB input image into a HSI image, which is a color space based on human color perception, in order to analyze the sampling errors that are caused by subpixel rendering. Then, it computes the difference between... View full abstract»

    Polariscopes are the basic instruments used for the analysis of the stress state of transparent materials. Polarized light passing through a 3D object carries the integrated effect of the stress field along the light path. Therefore, conventional polariscopes are not able to discern the stress state of objects involving multiple plates with mutual occlusions. In this paper we propose a novel exper...

    A fragile watermarking algorithm for hologram authentication is presented in this paper. In the proposed algorithm, the watermark is embedded in the discrete cosine transform (DCT) domain of a hologram. The watermarked hologram is stored in spatial domain with finite precision level. By enhancing the precision for storing the watermarked hologram pixels, the distortion produced by the proposed wat... View full abstract»

    This paper presents a novel FPGA-based hardware architecture for realtime diffraction computation of digital holography. The hardware circuit is based on Fresnel transform in basic form for diffraction computation. A novel pipeline is adopted in the circuit so that all the components are operated concurrently. The computation time of the circuit is comparable to a single fast Fourier transform (FF... View full abstract»

  • Perceived Color Impression for Spatially Mixed Colors

    Publication Year: 2014 , Page(s): 282 - 287

    Display devices adopt multiprimary pixels to represent chromatic images, and the individual primary pixels are discernible dimly within a certain range of spatial frequency. We systematically investigate the color impression of spatially mixed patterns of two colors from a barely discernible distance and show that the color impression differs greatly from their physically averaged colorimetric col...

  • Fabrication of p-Channel Amorphous Tin Oxide Thin-Film Transistors Using a Thermal Evaporation Process

    Publication Year: 2014 , Page(s): 288 - 292
    Cited by:  Papers (1)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (674 KB) |  | HTML iconHTML  

    In this study, p-channel amorphous tin oxide thin-film transistors (TFTs) were fabricated. A vacuum thermal evaporation method with an SnO powder source was used to deposit the tin-oxide active layer. Thermal annealing in N 2 and oxygen plasma treatment were used as post-deposition treatments to obtain p-channel switching capabilities from the tin-oxide active layer. We have achieved a field effec... View full abstract»

    The triple-targets magnetron co-sputtering system with three targets of In2O3, Ga2O3, and Zn was used to deposit amorphous indium gallium zinc oxide (a-IGZO) films. The deposited a-IGZO films were used as the channel layers of the transparent thin film transistors (TFTs). The In2O3 RF power of 50 W, Ga2O3 RF po... View full abstract»

  • A 2D-3D Switchable Driving Method for Reducing Power Consumption of Thin-Film Transistor Liquid Crystal Display TV With Film-Type Patterned Retarder

    Publication Year: 2014 , Page(s): 299 - 307

    This paper presents a new 2D-3D switchable driving method for a 3D thin-film transistor liquid crystal display (TFT-LCD) TV. The proposed driving method, which uses a film-type patterned retarder (FPR), can reduce unnecessary power consumption while displaying 2D images. The proposed driving method can change a part of a pixel according to the driving mode; the part is operated as a black matrix i... View full abstract»

  • Design and Assessment of a Depth-Fused Multi-Focal-Plane Display Prototype

    Depth-fused multi-focal-plane display was proposed to create a fixed-viewpoint volumetric display capable of rendering correct or nearly-correct focus cues in a stereoscopic display through a small number of discretely placed focal planes. It may effectively address the negative effects of conventional stereoscopic displays on depth perception accuracy and visual fatigue due to the lack of focus c... View full abstract»

    A hybrid thin film transistor (TFT) technology is proposed and demonstrated, which features a simultaneous fabrication of amorphous silicon (a-Si) TFTs with low off-current and polycrystalline silicon (poly-Si) TFTs with high carrier mobility on one substrate in one single process. For the a-Si TFT fabrication, the active film is the as-deposited LPCVD a-Si film, whereas, for the poly-Si TFT fabri... View full abstract»

    Conventional backlight dimming methods can hardly be used in edge type backlight LCD. In order to perform a power efficient backlight local dimming in LCD of mobile devices, a novel backlight module structure called partitioned light guide (PLG) was proposed. The PLG backlight module consists of independently controlled light sources, allowing the light luminance distribution to be controlled loca... View full abstract»
