  • Publication number: 20120249914
    Abstract: A display apparatus includes a first substrate including a plurality of pixels, a second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. Each pixel includes a gate electrode, a gate insulating layer, a semiconductor pattern, a source electrode, a drain electrode, a first electrode, and a second electrode. The first electrode includes a first portion overlapping the drain electrode and a second portion outside the first portion, and the second electrode does not overlap the first portion of the first electrode. The first electrode or the second electrode is formed as a single unitary structure.

  • Patent number: 7949324
    Abstract: The application discloses embodiments of methods and/or systems for compensating a transmission carrier leakage of an up-conversion mixer, a tranceiving circuit or apparatus embodying the same. One embodiment of a method can include detecting an I channel DC offset DCI0 and a Q channel DC offset DCQ0 generated by a reception carrier leakage from an output of a down-conversion mixer, detecting an I channel DC offset DCI and a Q channel DC offset DCQ from the output of the down-conversion mixer while varying a compensation parameter being inputted to an up-conversion mixer that has its output coupled to an input of the down-conversion mixer to determine the compensation parameter that can reduce or minimize a transmission carrier leakage. A combination of a transmission baseband signal and the determined compensation parameter can be transmitted using the up-conversion mixer and an antenna to compensate for the transmission carrier leakage.

  • Publication number: 20080157198
    Abstract: A high-voltage semiconductor device capable of preventing a substrate current from forming is disclosed. The method of manufacturing the high-voltage semiconductor device comprises forming a well in a semiconductor substrate, forming a device isolation film in a portion of the semiconductor substrate, forming a series of drift regions below the surface of the semiconductor substrate, forming a gate electrode on the surface of the semiconductor substrate so as to overlap a portion of at least one drift region, and forming a source and a drain region below the surface of the semiconductor substrate drift regions formed on opposing sides of the gate electrode. Advantageously, the substrate current of the semiconductor device is reduced and the operational withstand voltage is increased, improving the characteristics of the high-voltage transistor.
