Abstract: A display device includes a backlight unit generating light and a display panel displaying an image using the light from the backlight unit. The backlight unit includes a circuit board, a plurality of light emitting devices, a light guide member including a light incident surface, and a guide member disposed between a surface of the circuit board and the light incident surface. The guide member uniformly maintains a distance between the light incident surface and the light emitting devices. Thus, a light loss is reduced.

Abstract: A plurality of gray-scale values is extracted from image signals corresponding to a dimming area to calculate a mean value of the gray-scale values, and at least one of a variance, a standard deviation, a kurtosis, a skewness, a central moment, and an image moment is calculated using the mean value. Then, a representative gray-scale value corresponding to the dimming area is determined using the calculated values, and a dimming function for the light sources included in the dimming area is determined based on the representative gray-scale value. Then, the light sources included in the dimming area are driven based on the dimming function.

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.
