Abstract: A display apparatus is provided with a backlight and a driving apparatus for driving the backlight, the driving apparatus including: a switching unit which performs a switching operation to selectively supply driving power to the backlight in accordance with a driving signal; a signal synthesizer which outputs a synthesized signal by synthesizing a current control signal which controls a level of a backlight current flowing in the backlight and a dimming signal which controls dimming of the backlight; and a driver which generates the driving signal so that the backlight current flowing in the backlight reaches a predetermined target level based on the synthesized signal, outputs the driving signal to the switching unit, and controls the dimming of the backlight based on the synthesized signal.

Abstract: A backlight unit (BLU) capable of stably driving various light source modules, and a display apparatus using the same are provided. A display apparatus includes a display and a BLU. The BLU includes a light source module, a converter, a light source driving unit which drives the light source module using the output voltage of the converter, and a control unit which controls the output voltage of the converter based on the output voltage of the light source driving unit. Therefore, the ratio of the input voltage to the output voltage of the light source driving element may be maintained uniformly for various light source modules, so the light source modules can be stably driven.

Abstract: A light emitting module, a backlight unit (BLU) and a display apparatus are provided. The display apparatus includes a light emitting module including a light emitting unit including one or more light emitting elements which are electrically connected to each other; and a board on which the light emitting unit is disposed. The board includes a first terminal which is connected to a first end of the light emitting unit, and a ground portion which connects a second end of the light emitting unit to a ground. Therefore, it is possible to design a thinner BLU, thereby making a display device slimmer.

Abstract: A backlight assembly including: a power unit which outputs a current whose polarity is changed on a regular basis; a plurality of balancing units which is connected in parallel to the power unit; a plurality of light emitting diode (LED) modules each of which individually receives each current output by a corresponding balancing unit of the plurality of balancing units; and a driver which is connected between the plurality of balancing units and the plurality of LED modules, and forms a current route for each balancing unit included in the plurality of balancing units to balance a current supplied to two different LED modules during a single period where a polarity of a current output by the power unit is changed.

Abstract: A power supply for a television and a television including the same, the power supply including: a rectifier which rectifies input AC power; a converter which converts the rectified power into DC power through a switching control; a circuit board on which at least one of the rectifier and the converter is mounted; and an input connector which receives the AC power and is mounted on the circuit board such that a projecting height of the input connector projecting from the circuit board is substantially equal to or smaller than a projecting height of at least one of the rectifier and the converter.

Abstract: A display apparatus having a display and a backlight unit (BLU) which provides backlight to the display are provided. The BLU includes a first light source module in which a plurality of light sources are arranged, a second light source module in which a plurality of light sources are arranged, and a light source driving unit which drives the first light source module and second light source module. The first light source module and second light source module are connected to each other by a first connector.

Abstract: A power supply apparatus and display apparatus having the same are provided for outputting power, in which a standby mode selecting unit switches on and off a standby mode, a standby power supplying unit outputs standby power of a predetermined magnitude in the standby mode and temporarily outputs first auxiliary power when the standby mode is released by selecting of the standby mode selecting unit, a main power supplying unit outputs main power of a predetermined magnitude, and a backup power supplying unit continues to supply second auxiliary power, which is induced by the main power output from the main power supplying unit, to the main power supplying unit as driving power substituting the first auxiliary power. Thus, the output of standby power is increased when a standby mode is released, without increasing power consumption in the standby mode, using a standby power converter with small capacity.

Abstract: Disclosed is an infinitely variable speed transmission, including: a speed changing mechanism for primarily changing power from an engine into a necessary speed ratio, including: a sun gear disposed on an input shaft for transmitting power generated from the engine; a plurality of planet rollers which are disposed around the sun gear at a predetermined distance from each other, each planet roller having a truncated cone-shape and being revolvable around the sun gear and rotatable about its axis; a carrier for connecting the planet rollers with each other; a movable ring disposed to be circumscribed on outer tangential line of the planet rollers and movable by moving member along a longitudinal direction of the planet rollers to change a rotational speed of the planet rollers by varying an operating diameter so that an output speed outputted through the carriers connecting the planet roller with each other can be varied; and a second speed changing mechanism for changing the output speed from the speed changin
