  • Publication number: 20140312501
    Abstract: Structures and manufacturing processes of an ACF array using a non-random array of microcavities of predetermined configuration, shape and dimension. The manufacturing process includes fluidic filling of conductive particles onto a substrate or carrier web comprising a predetermined array of microcavities, of selective metallization of the array followed by filling the array with a filler material and a second selective metallization on the filled microcavity array. The thus prepared filled conductive microcavity array is then over-coated or laminated with an adhesive film. Cavities in the array, and particles filling the cavities, can have a unimodal, bimodal, or multimodal distribution.

  • Publication number: 20140313114
    Abstract: A column driver of a display device provides a high slew rate with lowered power requirements by using external switches connected to upper and bottom output buffers. The upper output buffer is driven between a first voltage rail and a second voltage rail, and outputs a first output signal in response to a first input signal and a second input signal. The bottom output buffer is driven between the second voltage rail and a third voltage rail, and outputs a second output signal in response to a third input signal and a fourth input signal. A first switch group selectively provides input for the upper output buffer and the bottom output buffer. A second switch group feeds back the first and the second output signals to the first or the second input terminal of each of the upper output buffer and the bottom output buffer.
