The GaN-based semiconductor device may include a heat dissipation substrate (that is, a thermal conductive substrate); a GaN-based multi-layer arranged on the heat dissipation substrate and having N-face polarity; and a heterostructure field effect transistor (HFET) or a Schottky electrode arranged on the GaN-based multi-layer. The HFET device may include a gate having a double recess structure. While such a GaN-based semiconductor device is being manufactured, a wafer bonding process and a laser lift-off process may be used.

Abstract: A method and apparatus for processing an image. The method and apparatus may each perform the operations of extracting motion information of an input signal calculating true motion information, which indicates whether an object of interest moves and an area where the object of interest moved, from the motion information, and deinterlacing the input signal by using the motion information with respect to an area that is determined to have true motion, such that the input signal is in a form before being compressed for transmission. The method and apparatus may further perform an operation of converting resolution of the deinterlaced input signal. In the converting of the resolution, the resolution may be converted by using the true motion information and the motion information.

Abstract: Methods and related liquid crystal display devices are disclosed that reduce/avoid a tearing effect in displayed images. A scan time of a scan clock signal of a display is detected. A write time of a write clock signal that writes data into a memory for display on the display is detected. The write time is regulated in response to a comparison of the scan time of the scan clock signal to the write time of the write clock signal.
