摘要： A light source apparatus includes a light source disposed adjacent to a side portion of a light guide plate and a light source driver driving the light source. The light source driver includes a booster and a protecting circuit. The booster boosts an input voltage to a driving voltage for driving the light source. The protecting circuit selectively cuts off the input voltage applied to the booster according to an output current of the booster, reducing the risk of damage to the driver due to shorts, overcurrents, or the like.

摘要： A piston support structure for a reciprocating compressor is provided that includes a piston receiving a linear reciprocating driving power generated by a reciprocating motor. The piston is in a compression space formed in a cylinder and a first resonant spring and a second resonant spring are positioned on both sides of the piston. The first resonant spring and the second resonant spring elastically support the linear reciprocating motion of the piston. The spring constant of the second resonant spring opposite to the first resonant spring is larger than the spring constant of the first resonant spring positioned on the side of the compression space of the cylinder. Accordingly, the stress concentration of the second resonant springs for elastically supporting the piston is reduced. Accordingly, it is possible to prevent the fatigue of the second resonant springs and to extend the durability of the resonant springs.

摘要： A backlight assembly outputs scan signals having a scanning frequency synchronized with a frame frequency to sequentially drive light emitting blocks providing a light to a display panel. A dimming step of each light emitting block corresponds to one of a plurality of dimming steps in response to local dimming data. A dimming clock having a value obtained by dividing a value obtained by multiplying the scanning frequency and the number is dimming steps by a duty ratio of each scan signal is generated. The dimming step of each light emitting block is counted using the dimming clock, and the counted values are combined with the scan signals to generate dimming signals having a dimming duty ratio corresponding to the dimming step of the light emitting blocks.
