William Yao 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: 8570284
    Abstract: Provided is a display comprising a first plurality of light-emitting elements forming an annular bar graph, and a numerical display within the annular bar graph. The annular bar graph displays information graphically, and the numerical display simultaneously displays the same information numerically.
    Type: Grant

  • Patent number: 7532264
    Abstract: An ESD protection system for an image sensor array includes a two-dimensional array of pixels formed on a substrate. Each of the pixels is connected to a gate line and a data line. The system includes a common ESD bus and at least one ESD protection circuit formed on the substrate. The protection circuit includes: a pair of thin film transistors connected in a back-to-back configuration with a first terminal connected to one of the gate lines, and a second terminal connected to the common ESD bus. Upon the occurrence of an electrostatic discharge onto the gate line causing the voltage across the terminals to exceed a threshold value, the protection circuit discharges the ESD charge from the gate line to the ESD bus, thereby preventing damage to each of the switching transistors in the pixels connected to the gate line.

  • Patent number: 7265327
    Abstract: Photodetecting devices or arrays and methods of making such devices or arrays. In one exemplary embodiment, a photodetecting array includes a plurality of detecting cells arranged in an array, each of the detecting cells including a photodiode, a plurality of data lines coupled to the detecting cells, and a mesh of bias voltage lines which comprise first bias lines disposed substantially parallel to gate lines which are coupled to the detecting cells and second bias lines disposed substantially perpendicularly to the gate lines, wherein the total length of the first bias lines exceeds a total length of the second bias lines.

  • Patent number: 5682211
    Abstract: The invention provides an integrated dark matrix for an active matrix liquid crystal display. A plurality of pixel electrodes overlap at least one of a plurality of gate lines and a plurality of data lines. A perimeter of the pixel electrodes overlaps the gate lines and/or data lines by twice the distance that the pixel electrode is above the gate and data lines, respectively to obtain a viewing angle of over 60 degrees.
