  • Publication number: 20140022494
    Abstract: A liquid crystal display is provided, which includes a first substrate, a plurality of pixels, a second substrate, a plurality of floating electrodes, and a liquid crystal layer. The pixels are arranged in an array on the first substrate, and each of the pixels includes a first electrode and a second electrode, wherein a space is maintained between the first electrode and the second electrode. The floating electrodes are disposed on the second substrate and above the spaces. The liquid crystal layer is located between the first substrate and the second substrate, wherein the liquid crystal layer is optically isotropic when the first electrode and the second electrode have no voltage difference; and the liquid crystal layer is optically anisotropic when the first electrode and the second electrode have a voltage difference therebetween.

  • Patent number: 8502952
    Abstract: Color cholesteric liquid crystal display devices and fabrication methods thereof are provided. The color cholesteric liquid crystal display device includes a first substrate, a second substrate and a gap interposed therebetween. A patterned enclosed structure, formed by adhering a first patterned enclosed structure on the first substrate and a second patterned enclosed structure on the second substrate, is interposed between the first substrate and the second substrate, dividing a plurality of color sub-pixel channels. A plurality of the color cholesteric liquid crystals are respectively filled into each of the color sub-pixel channel, wherein the first patterned enclosed structure is tightly adhered to the second patterned enclosed structure so as to prevent mixing of the color cholesteric liquid crystals between adjacent color sub-pixel channels.

  • Publication number: 20130020186
    Abstract: A touch sensing apparatus has a plurality of unit regions, and each of the unit regions includes a first substrate, a second substrate and a spacer structure. The first substrate has a first electrode layer thereon. The second substrate is disposed opposite to the first substrate and has a second electrode thereon. The spacer structure is disposed between the first substrate and the second substrate. In particular, there are plural of sensing units in each of the unit regions, and sensing trigger forces of the sensing units in the unit region are not completely the same.

  • Publication number: 20120218104
    Abstract: A signal transmitting apparatus in accordance with the present invention comprises two connecting wires. Two connectors are respectively to two opposite ends of each of the two connecting wires. Two alarm devices are mounted on the two connecting wires and each near a corresponding one of the two connectors. Two conducting wires are respectively connected to the two alarm devices to form a closed circuit such that the two alarm devices are synchronously operated when one of the two alarm devices is connected to a power source for user to confirm a connecting wire is operated in somewhere.

  • Publication number: 20040015440
    Abstract: A network resource management system includes: a server a server for constructing therein a database and connection with web sites; an encoder disposed in the server for encoding files downloaded via the server so as to convert the file into an encrypted format; and a decoding software disposed in the computer at a client user end for checking identity and code of the client user against identity in the server and decoding the downloaded file to recover the same into the original file format; whereby all the files downloaded from the server are in an encoded encrypted format upon entering into the computer at the client user end and cannot be displayed in the original file format, and the files have to be encoded to the original format by exclusive decoding software after legitimate licensing and transaction verification for use by the client user, thereby effectively preventing adaptation of network resources.
