A method for providing a User Interface (UI), in which a common function is mapped to a plurality of motions, and a device adopting the method is provided. The method includes performing a function commonly mapped to a plurality of motions when a user motion falls within any one of the plurality of motions. Thus, as a plurality of motions for instructing a specific function exists, a user may input a familiar or desired motion, to thereby enable the user to input a command for a function in a more convenient and free manner.

A termination value for a pin of a semiconductor device is set to a first value if a pin signal has a first logic state at an edge of a control signal, and to a second value if the pin signal has a second logic state at the edge of the control signal. Alternatively, a respective logic state of a first control signal is determined at an edge of a second control signal, and a respective logic state of the pin signal is determined at the edge of the second control signal. The termination value is set depending on such respective logic states.

A light generating device includes a circuit board and a plurality of light source units. Each of the light source units includes a first light source group and a second light source group. The first light source group includes at least two light sources spaced apart from each other by a first distance and the second light source group including at least two light sources. Each of the light sources of the second light source group is spaced apart from a first virtual line segment connecting centers of the light sources of the first light source group by a second distance that is larger than the first distance. A second virtual line segment connecting centers of the light sources of the second light source group crosses the first virtual line segment. Therefore, a number of light sources is reduced to lower a cost of manufacturing the light generating device

An operating system of a liquefied natural gas ship for performing sub-cooled liquefaction of boil-off gas includes a boil-off gas compressor, a cryogenic heat exchanger connected to a refrigerator system, and a first check valve and a first pressure control valve, installed in a pipe between a liquefied natural gas phase separator and a gas combustion unit, and a second check valve and a second pressure control valve, installed in a parallel pipe connected to the pipe in parallel. The parallel pipe is connected to a pipe between the boil-off gas compressor and the cryogenic heat exchanger such that boil-off gas is supplied to an upper vapor region of the liquefied natural gas phase separator. Thus, pressure and level of the liquefied natural gas phase separator are stably controlled. Power consumption is effectively reduced, and economical efficiency is achieved by stable operating pressure and level of the liquefied natural gas phase separator.

In a display panel and a display device having the display panel, the display device has a first pixel area, a second pixel area, a third pixel area and a fourth pixel area. A red fluorescent member, a green fluorescent member and a yellow fluorescent member are formed in the first pixel area, the second pixel area and the third pixel area. The red fluorescent member emits a red light by using a blue light incident thereon. The green fluorescent member emits a green light by using a blue light incident thereon. The yellow fluorescent member emits a white light by using a blue light incident thereon. A blue light incident on the fourth pixel area passes through the fourth pixel area so that the blue light is irradiated from the fourth pixel area.

A frequency measuring circuit may include an edge detector, a charge pump, and an analog-to-digital (A/D) converter. The edge detector may be configured to generate an output pulse responsive to an edge of an input clock signal. The charge pump may be configured to generate an output signal responsive to the output pulse from the edge detector. The analog-to-digital (A/D) converter may be configured to convert the output signal into a digital value representing a frequency of the input clock signal. Related methods and integrated circuit memory devices are also discussed.
摘要:
In a machine-implemented method of local dimming a light source of a light source block for driving the light source block to provide a plurality of image regions with light, duty ratios of a first light source and a second light source adjacent to the first light source are initially determined by using a first target luminance value of a first image region closest to the first light source and a second target luminance value of a second image region closest to the second light source. The initially determined duty ratios are compensated by using a target luminance value of a remaining image region excluding the first and second image regions among the image regions receiving the light generated from the first and second first light sources. The first and second first light sources are driven by using the compensated duty ratios.
