    摘要: A backlight assembly a plurality of first light-emitting chips for emitting light and a thermistor for indicating the temperature of the first light-emitting chips. The first light-emitting chips emit first color light and are connected in series to each other. The thermistor may be connected in series to the first light-emitting chips and has an electrical resistance that decreases with an increase of its temperature. The light amount emitted by the first light-emitting chips is controlled by pulse width modulating the current driving the first light-emitting chips based on the temperature (resistance) of the thermistor and based on received image data. Thus, a decrease in brightness due to temperature variation may be compensated for while performing color dimming.

    摘要: A light source apparatus includes light-emitting blocks, a local dimming control part and a light source driving part driving. The light-emitting blocks include a first-color light source which emits first-color light and a second-color light source which emits second-color light. The second-color light source includes a third-color chip and a fourth-color phosphor disposed on the third-color chip, and is disposed as one package to emit the second-color light therefrom. The local dimming control part compensates a driving current of the first-color light source and a driving current of the second-color light source of each of the light-emitting blocks. The light source driving part drives the first-color light source and the second-color light sources based on the driving current of the first-color light source and the a driving current of the second-color light source, respectively, each compensated by the local dimming control part.

    摘要: A backlighting assembly for an LCD display is divided into a plurality of selective dimming areas each having a respective plurality of light generating blocks. A plurality of driving units supply power to the light generating blocks. The light generating blocks are grouped into light source groups. Each of the driving units supplies power to at least one light generating block in a first light source group and a second light generating block in a second light source group but not to all the light generating blocks in any one light source group. Light generating blocks connected to a same driving unit may be distributedly arranged to be nonadjacent to one another. Plural driving units are used to fully power a brightly lit one dimming area, thereby reducing the loads on the individual driving units and preventing overheating.

    摘要: In accordance with one or more embodiments of the present invention, a light source module includes a light source, a frame plate, and an insulation structure. The frame plate includes a plurality of light source pad portions, a power wiring portion, and a peripheral portion. The power wiring portion is electrically connected to the light source to be formed in the vicinity of the light source pad portion. A boundary area of the power wiring portion corresponding to the peripheral portion and the light source pad portion is formed to be open, so that the power wiring portion is spaced apart from the peripheral portion and the light source pad portion. The insulation structure is formed in the boundary area to electrically insulate the power wiring portion from the frame plate. In one aspect, the volume, weight, and manufacturing costs of the light source module may be reduced, and a process of individually packaging light sources may be considered unnecessary.
