    We present a new pixel circuit on glass using hydrogenated amorphous silicon (a-Si:H) for driving polymer-stabilized blue-phase liquid crystal displays (BPLCDs). Different from conventional nematics, BPLC demands a large dielectric anisotropy in order to lower the operation voltage. As a result, the pixel's capacitance is increased by ~ 10×, which seriously limits the charging capability... View full abstract»

    A thorough study on the gate driver integrated with hydrogenated amorphous-silicon thin-film transistors (a-Si:H TFTs) for active-matrix flat-panel display (AM-FPD) is carried out in this work. The single stage circuit of the a-Si:H gate driver consists of input, pull-up, pull-down, and low-level holding units. The operation principle of the driver is described in detail. The subtle static and dyn... View full abstract»

    This work presents a new simple passive 3D stylus and its associated stroke reconstruction algorithm for capacitive touch panels that detects the x,y -directional position and z -directional strength without the help of a pressure sensor. The proposed algorithm can successfully detect touch information while eliminating noise. Moreover, unintended touch will be recognized and ... View full abstract»

  • Figure of Merit of Polymer-Stabilized Blue Phase Liquid Crystals

    A figure of merit (FoM), defined as the ratio of Kerr constant to response time, is used to characterize and compare the electro-optic performance of polymer-stabilized blue phase liquid crystals (BPLCs). Increasing the dielectric anisotropy of LC host enhances Kerr constant and lowers the operation voltage, but its associated high viscosity dramatically increases the response time. As a result, t...

  • Photo-Related Stress Effects in a-SiGe:H Thin Film Transistors for Infrared Image Sensors

    Publication Year: 2013, Page(s):30 - 36
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1234 KB) | HTML iconHTML

    The effects of photo-related stress on the electrical performances of a-SiGe:H thin-film transistors (TFTs) were investigated in comparison with a-Si:H TFTs. Compared with a-Si:H TFTs, the a-SiGe:H TFTs show better stability to the light stress because the number of electrons involved in the creation of dangling bonds are smaller in a-SiGe:H TFTs, resulting in less light-induced degradation.

  • Non-Homogeneity of Lateral Resolution in Integral Imaging

    We evaluate the lateral resolution in reconstructed integral images. Our analysis takes into account both the diffraction effects in the image capture stage and the lack of homogeneity and isotropy in the reconstruction stage. We have used Monte Carlo simulation in order to assign a value for the resolution limit to any reconstruction plane. We have modelled the resolution behavior. Although in ge... View full abstract»

    Contrast enhancement involves transforming the intensity of pixels from the original state to feature significant impaction on many display devices, including laptops, PDAs, monitors, mobile camera phones, and so on. This paper proposes a new method to enhance the contrast of the input image and video based on Bezier curve. In order to enhance the quality and reduce the processing time, control po...

    Recently, three-dimensional (3D) object reconstruction using photon counting integral imaging (PCII) based on grayscale elemental images has been reported. In this paper, we present a multispectral PCII system using Bayer elemental images for multispectral visualization of photon limited 3D scenes. We measure the accuracy as well as the speed of demosaicing algorithms to estimate multispectral 3D ... View full abstract»

    In this paper, we present a 3D photon counting axially distributed image sensing system using statistical approaches, such as a maximum-likelihood estimation and total variation maximum a posteriori expectation maximization, to enhance the visual quality of 2D photon counting images and obtain better 3D reconstructed images. Conventional photon counting integral imaging is implemented by using a l... View full abstract»
