  • Publication number: 20110108936
    Abstract: A pressure detector is disclosed having an organic transistor, a pressure-detecting layer and a first electrode. The organic transistor includes an emitter, an organic layer, a grid formed with holes, and a collector, the organic layer being sandwiched between the emitter and the collector. The pressure-detecting layer is formed on the organic transistor such that the collector is sandwiched between the organic layer and the pressure-detecting layer. The first electrode is formed on the pressure-detecting layer such that the pressure-detecting layer is sandwiched between the collector and the first electrode. The area of the active region of the pressure detector is determined by the overlapped area of the electrodes, thereby reducing the pitch of the electrodes and thus the size of the pressure detector.

  • Publication number: 20100316182
    Abstract: A shift register includes a plurality of shift register units each including an input circuit, a pull-up circuit and a pull-down circuit. The shift register unit receives an input voltage at an input end and provides an output voltage at an output end. The input circuit controls the signal transmission path between a first clock signal and a first node according to the input voltage. The pull-up circuit controls the signal transmission path between a second clock signal and the output end according to the level of the first node. The pull-down circuit includes a pull-down unit and a control unit. The pull-down unit maintains the level of the first node or the output end according to the level of the second node. The control unit maintains the level of the second node according to the first clock signal, the second clock signal and the level of the first node.

  • Publication number: 20100301504
    Abstract: A method of making a light-guiding module includes the steps of applying a layer of light guide material containing methyl methacrylate oligomers on a reflector, and polymerizing the methyl methacrylate oligomers of the light guide material at a temperature ranging from 60 to 65° C. for 2.5 to 3 hours to form a light guide plate containing polymethylmethacrylate and integrally combining the reflector. Since there is no any gap between the light guide plate and the reflector, the light-guiding module reduces light loss, and improves the luminous efficiency of the backlight unit in which the light-guiding module is used.

  • Publication number: 20080139069
    Abstract: A spunbond non-woven containing bamboo charcoal is provided, which has functions of thermal insulation, deodorization and acoustical absorption and including a plurality of non-woven fibers. The non-woven fibers include a bamboo charcoal mixture including bamboo charcoal and a polymer, wherein the bamboo charcoal accounts for 0.05˜35 wt % based on the total amount of the bamboo charcoal mixture. The present invention additionally provides a method for fabricating the single-component or multi-component spunbond non-woven containing bamboo charcoal. A bamboo charcoal grain containing bamboo charcoal is prepared, wherein the bamboo charcoal has an amount of 0.05˜35 wt % based on the total weight of the bamboo charcoal grain. Next, the bamboo charcoal grain or the bamboo charcoal grain mixed with a polymer is spunbond with another polymer by using a spin apparatus to form a non-woven.
