  • Publication number: 20130127697
    Abstract: A multiplexer circuit includes multiple groups of switches and multiple groups of control lines. Each control line in each one of the groups of control lines is coupled to a control end of at least one switch in corresponding one of the groups of switches, and each group of control lines is configured for synchronously transmitting an identical group of control signals. A display panel and method for transmitting signals in a display panel is also disclosed herein.

  • Publication number: 20120146962
    Abstract: An active liquid crystal display panel includes a pixel array, a gate driving circuit, a data driving circuit, and an analog buffer. The gate driving circuit is used for driving M first scan lines where M is a natural number. The analog buffer is coupled to the gate driving circuit and includes M buffer circuits and a regulator. Each buffer circuit drives a corresponding second scan line according to an output signal of a corresponding first scan line of the M first scan lines, and the regulator is used for maintaining at least one reference voltage supplied to the M buffer circuits.

  • Publication number: 20120104402
    Abstract: In one aspect of the invention, an analog buffer circuit includes a p-channel field effect transistor (PTFT) and an n-channel field effect transistor (NTFT). Each of the PTFT and NTFT has a source region and a drain region defining a channel region therebetween, formed on a substrate such that the drain regions of the PTFT and the NTFT are in substantial contact with each other, a gate layer formed over and insulated from the corresponding channel region, a source electrode insulated from the gate layer and electrically connected to the corresponding source region, and a common drain electrode insulated from the gate layer and the source electrode, and is electrically connected to the drain regions of both the PTFT and the NTFT through a via defined over the depletion region.

  • Patent number: 7163366
    Abstract: A screw includes a first thread on the shank and located close to the point of the shank, and a second thread which is connected to the first thread and extends toward the head of the screw. Each of the first and second threads includes an upper flank and a lower flank. A first angle is defined by an intersection of the upper flank and the lower flank of the first thread, and is larger than a second angle defined by an intersection of the upper flank and the lower flank of the second thread. The first thread bears larger torque and the second thread includes sharper cutting edges.
