    A multi-domain vertical alignment liquid crystal display (MVA LCD) using a negative C-plate and a biaxial film is proposed to obtain an achromatic dark state. In comparison to conventional approach which uses a negative C-plate and a positive A-plate, the maximum light leakage over entire viewing cone is reduced by ~ 6X at lambda = 450 nm and ~ 4X at lambda = 650 nm. The achromatic dark state is essential for improving the contrast ratio, viewing angle and color saturation of MVA LCDs. View full abstract»

    In this paper, we demonstrated the Inkjet print method to fabricate a ultraviolet (UV)-curable epoxy microlens deflecting array with controllable curvature and filling factor, by which a 7-in light guide plate with 82% uniformity and 70% light efficiency was successfully implemented. The microlenses can be directly formed by plastic discharged by inkjet head, eliminating the need for molds and slashing development time. Proposed method will certainly has a promising impact on rapid prototyping and other specialized microfeatures due to its simplicity and versatility. View full abstract»

  • Low Frequency Architecture for Multi-Lamp CCFL Systems With Capacitive Ignition

    A low frequency architecture is proposed for driving parallel cold cathode fluorescent lamps (CCFLs) in large screen liquid crystal display (LCD) TV backlighting applications. Key to the architecture is a proposed capacitive coupling approach for aiding lamp ignition. A dc voltage is applied to the lamp electrodes while an ac voltage is applied to an external plate for capacitive coupling. The result is reliable, simultaneous ignition of parallel lamps with a required applied dc voltage near the lamp steady-state operating voltage. The complete system architecture includes a single high voltage converter, a pulse lamp ignition circuit, current control circuits and a single backlight controller. The topology is capable of driving a large number of parallel lamps with independent lamp current regulation, while avoiding ac coupling losses in steady-state operation and achieving significant reduction in reactive components when compared to typical high frequency ac ballast designs. Experimental results are presented for a system of four parallel 250 mm length lamps, demonstrating simultaneous parallel lamp ignition and dc current regulation. View full abstract»

    A mask-free inkjet printing (IJP) process has been developed to fabricate color filters. The coffee ring effect was used to create a ring-edged bank array with fine structures by IJP of poly(methylmethacrylate). After the color filtering inks were deposited in the banks, a color filter panel was made without any transitional photolithography process. The resulting color coordinates of the three primary colors on the chromaticity diagram are (0.70, 0.30), (0.33, 0.60) and (0.14, 0.09), respectively, covering 67.8% of the National Television System Committee standard. This process can be used with flexible substrates to produce low-cost inkjet printed color filters. View full abstract»
