Abstract: The present invention relates to a composition for etching, comprising a first inorganic acid, a first additive represented by Chemical Formula 1, and a solvent. The composition for etching is a high-selectivity composition that can selectively remove a nitride film while minimizing the etch rate of an oxide film, and which does not have problems such as particle generation, which adversely affect the device characteristics.

Abstract: A display device includes at least a first luminance range and a second luminance range which includes a luminance different from the first luminance range. In a boundary area of a second dimming range corresponding to the second luminance range and which is adjacent to a first dimming range corresponding to the first luminance range, a reference luminance emitted from a pixel is maintained as a first constant luminance value, and an off-duty number, which is the number of periods in which the pixel is turned off during one frame, is gradually increased by an emission control signal.

Abstract: A bidirectionally openable console includes side lid portions, a center lid portion positioned between the side lid portions, a first button unit positioned at a front end of the center lid portion, a second button unit positioned at a rear end of the center lid portion, and rotary units configured to be respectively rotated by movement of the first and second button units. The console further includes: fastening units, each of which is constructed such that, when an opening request input is applied to a corresponding button unit, a corresponding rotary unit is rotated to retract a central shaft portion into the center lid portion; hinge units, each of which is rotated together with the center lid portion when the center lid portion is opened, and locking units, each of which restricts movement of the fastening unit when the center lid portion is closed.

Abstract: A driver for a liquid crystal lens, an imaging apparatus and a temperature controlling method thereof, include: a liquid crystal lens which adjusts a focal length according to a voltage applied thereto; a lens driver which applies the voltage to the liquid crystal lens; a sensor driver which detects a temperature of the liquid crystal lens, compensates for the detected temperature, and determines whether the compensated temperatures maintains a preset range for the driver for the liquid crystal lens to perform a control operation; and a heater driver which, according to the determination by the sensor driver, controls heat generation of the liquid crystal lens to maintain a temperature of the liquid crystal lens in the preset range. Thus, the driver detects a temperature of the liquid crystal lens accurately by compensating for a resistance value from the liquid crystal lens to thereby maintain stability of the imaging apparatus.

Abstract: A network connection method for an asynchronous mobile terminal is provided for reducing connection latency and power consumption. A network connection method for an asynchronous mobile terminal includes displaying a list of operators identified by scanning frequencies in a manual network selection mode, acquiring, when one of the operators is selected from the list, synchronization through a frequency of the selected operator, and connecting to a network through the frequency for receiving a service. The network connection method enables a mobile terminal to select an operator network through a single frequency scanning process unlike the convention method which performs frequency scanning twice, thereby reducing connection latency and power consumption of the mobile terminal.
