Tzung-Hsien Chen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8723067
    Abstract: A capacitive touch control sensor includes a plurality of first electrodes, a plurality of first electrode wires, a plurality of second electrodes, a plurality of second electrode wires. The first and second electrodes are disposed at predetermined interval. The first electrodes have two opposite sensor units and a connecting unit which bridges there-between. Each of the first electrode wires connects one of the first electrodes. Each of the second electrode wires connects more than one of the second electrodes in a same column. The first and second electrodes are arranged alternatively and the neighboring second electrodes are disposed respectively at either side of the connecting unit of the first electrodes.
    Type: Grant

  • Publication number: 20070030237
    Abstract: A source driving method and a source driver for a liquid crystal display device having a plurality of pixels, wherein each pixel comprises a first color sub-pixel with a first displaying wavelength, a second color sub-pixel with a second displaying wavelength less than the first displaying wavelength, and a third color sub-pixel with a third displaying wavelength less than the second displaying wavelength are provided. First, a digital data is received. Then, a digital to analog process is performed to convert the digital data into an analog data. Next, the analog data is sequentially selected and output to the first color sub-pixel, the second color sub-pixel, and then the third color sub-pixel of the selected pixel. The source driving method can improve the image color fidelity of the liquid crystal display device.
