  • Patent number: 8711136
    Abstract: The present invention provides a voltage transfer function, a luminance transfer function, and a transfer factors (for example, efficiency, critical point, and slope) between these two functions, derives the correlation (based on the condition change in all cases) between an input grayscale voltage and output luminance, and calibrates the input grayscale voltage by a difference between measurement luminance and target luminance using the transfer functions. Therefore, the present invention can respond to change in conditions for all cases, and increase the accuracy, easiness, and generalization of calibration compared to the existing calibration scheme that relies on the lookup table by checking the actual measurement data and readjusting the transfer factors in each calibration stage. Moreover, the present invention can further increase the manufacturing yield by an average of 35% than the existing yield, significantly saving the manufacturing cost.

  • Patent number: 8711108
    Abstract: A substantially transparent touch sensor panel having co-planar single-layer touch sensors and traces fabricated on a single side of a substrate for detecting single or multi-touch events. The touch sensor elements can be fabricated in columns and rows, with each sensor element in a row adjacent to a sensor element in a column. By using a board as the dielectric to connect traces from multiple sensor elements in each row, rather than using a dielectric layer on the substrate upon which the sensor elements and traces are formed, the sensor elements and traces on the substrate can be formed by simply patterning a single layer of conductive material on the substrate, which can simplify the manufacturing process of the substrate from a complexity and cost perspective.

  • Patent number: 8692777
    Abstract: The testing of a multi-touch sensor panel for opens and shorts on its drive and sense lines is disclosed by placing a substantially ungrounded conductor diagonally over the touch sensor panel so that at least a portion of every drive line and every sense line is covered by the substantially ungrounded conductor. Pixels under the substantially ungrounded conductor can have strongly positive pixels, while pixels outside the substantially ungrounded conductor can have negative pixels. With the substantially ungrounded conductor in place, a backdrop of negative pixels is formed, and an image of touch can be obtained. By analyzing the image of touch, any opens and shorts on the drive and sense lines, any shorts between a drive and a sense line, or any open drive and sense lines can be quickly identified against the backdrop of negative pixels.
