Abstract: An approach is provided for a light source module and a display device including the same. The light source module includes two first light source packages configured to emit light of a first color, one or more second light source packages disposed between the two first light source packages, and a plurality of third light source packages disposed between the two first light source packages and alternately arranged with the one or more second light source packages. The one or more second light source packages are configured to emit light of the first color and the plurality of third light source packages are configured to emit light of a second color. An intensity of light emitted from each of the one or more second light source packages is approximately twice an intensity of light emitted from each of the two first light source packages.

Abstract: A display apparatus with at least two light guide plates, each including a light incident surface and a light exiting surface, the light guide plates being spaced apart from each other so as to form a gap therebetween. The display apparatus also has a light source disposed adjacent to at least one side portion of the light guide plates to emit light to the light incident surface, a display panel positioned to receive light from the light exiting surfaces to facilitate display of an image, and a diffusion member. The diffusion member covers the gap, so as to diffuse light directed toward the display panel.

Abstract: A display device with improved display quality is provided. The display device includes an LED light source emitting light, a display panel receiving the light to display an image, and a backlight driver adjusting the magnitude and the duty ratio of an LED current I_LED flowing through the LED light source. The waveform of the LED current I_LED includes at least one of a rising section in which the magnitude of the LED current more gradually increases from a turn-off current value to a peak value, and a falling section in which the magnitude of the LED current more gradually decreases from the peak value to the turn-off current value. This acts to reduce waterfall noise.

Abstract: In order to perform local dimming, a driving dimming duty cycle is generated using a target gamma curve (TGV), wherein the driving dimming duty cycle corresponds to a representative grayscale value (RGV) of each of a plurality of dimming unit areas. Each of a plurality of light unit blocks of a light source is driven based on the driving dimming duty cycle, wherein the light unit blocks correspond to the dimming unit areas, respectively. Therefore, a display apparatus may display an image having a higher contrast ratio than normal.
