    Abstract: An insulated gate bipolar transistor (IGBT) is provided comprising a semiconductor substrate having the following regions in sequence: (i) a first region of a first conductive type having opposing surfaces, a column region of a second conductive type within the first region extending from a first of said opposing surfaces; (ii) a drift region of the second conductive type; (iii) a second region of the first conductive type, and (iv) a third region of the second conductive type. There is provided a gate electrode disposed to form a channel between the third region and the drift region, a first electrode operatively connected to the second region and the third region, a second electrode operatively connected to the first region and the column region. The arrangement of the IGBT is such that the column region is spaced from a second surface of the opposing surfaces of the first region, whereby a forward conduction path extends sequentially through the third region, the second region, the drift region, and the first region, and whereby a reverse conduction path extends sequentially through the second region, the drift region, the first region and the column region. Reverse conduction of the IGBT occurs through a thyristor structure which is embedded in the IGBT. Such an IGBT structure is advantageous over a reverse conducting IGBT structure in which an anti-parallel diode is integrated or embedded because it provides improved reverse conduction and snapback performance.

    Abstract: A double-layer switchable stereo liquid crystal display includes a timing controller, a microprocessor, a backlight module, a first liquid crystal panel, a controller, and a second liquid crystal panel. The timing controller receives an image signal and generates a left/right eye signal and a two-dimensional/three-dimensional control signal. The microprocessor outputs the image signal, and generates a control signal and a backlight control signal according to output timing of the image signal. The first liquid crystal panel receives and displays the image signal. The controller outputs a voltage control signal according to the control signal. The second liquid crystal panel rotates liquid crystal within the second liquid crystal panel according to the voltage control signal. A period for the second liquid crystal panel rotating the liquid crystal to a second angle is longer than a period for the second liquid crystal panel rotating the liquid crystal to a first angle.

    Abstract: A phase locked loop and an associated alignment method are provided. A disclosed phase locked loop receives a reference signal to provide a feedback signal. The phase locked loop is first opened. When the phase locked loop is open, a frequency range of an oscillating signal from a voltage-controlled oscillator is substantially selected. The feedback signal is provided according to the oscillation signal. After the frequency range is selected, the phase locked loop is kept open and the phases of the reference signal and the feedback signal are substantially aligned. The phase locked loop is then closed after the reference signal and the feedback signal are aligned.
