  • Publication number: 20090008162
    Abstract: An input device of capacitive touchpad is capable of generating an inducing capacitance through holding by a user. The claimed input device includes a pen nib which is made of/from an electric-conductive material, a pen body providing wider holding area for the user and a connect part for holding by the user. The pen nib and the connect part have an inlaying component in pairs such as mortise to lodged in or inset into each other. The pen nib may be made of/from an elastic or soft electric-conductive material which is made of/from a polyester compound doped or mixed with a metal powder or having metallic covering stuffed with the elastic or soft electric-conductive material for increasing the contact surface area. Accordingly, the present invention solves the available pad area shortening problem and the capacitance sensing variation result from the sweat of finger.

  • Publication number: 20060243968
    Abstract: An organic electroluminescent device for preventing long distance short comprises an isolated separating layer unit provided on an organic light emitting layer and the two sides of an second electrode, and an isolating trench further provided between a first isolated separating layer and a second isolated separating layer of the isolated separating layer unit. Accordingly, the isolating trench is provided for preventing the irregular electrical contact from the first electrical conducting layer of the top of the first isolated separating layer and the second electrical conducting layer of the top of the second isolated separating layer, that is, the irregularly lighting by the pixels can be prevented from the long distance short for the organic electroluminescent device.

  • Publication number: 20060208633
    Abstract: An organic electroluminescent device with improved lifetime and a method of fabricating the same are provided. The device comprises a barrier layer on an upper surface of a color filter, and etching and removing part of the barrier layer uncovered by first electrodes to form moistness removed channel after defining and forming at least one first electrode on an upper surface of the barrier layer. It is convenient to bake and eliminate a solvent or mist existed in the color filter in a baking process, thereby reducing speed of going bad of the organic light emitting layer and effectively improving lifetime of the organic electroluminescent device.
