    摘要： 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.

    摘要： 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.

    摘要： A liquid crystal display apparatus includes a liquid crystal display panel which displays an image, a light guide plate, a backlight unit including a light source part which generates and supplies light, and a panel temperature adjusting member on a surface of the liquid crystal display panel. The panel temperature adjusting member includes a transparent resistor, and a power supply which supplies power to the transparent resistor. The transparent resistor emits a larger amount of heat to a region of the liquid crystal display panel, which is distant from the light source part, than to a region close to the light source part, such that the liquid crystal display panel has uniform temperature distribution.

    摘要： A light source module of a display device comprises light-emitting blocks each of which comprises multiple sets of light sources, with different sets emitting different colors (e.g. red, green and blue). Each set is independently controllable according to one or more driving parameters. A local-dimming method comprises: (a) in each color-dimming period, driving each light-emitting block by the first color-dimming process; (b) in each compensating period, driving each light-emitting block by a full-color process which is independent of the image; (c) in each compensating period, sensing emitted light and determining the one or more driving parameters' reference driving values operable to generate a reference color; (d) in at least one of the color-dimming and compensating periods, driving each light-emitting block using the one or more driving parameters' values which depend on the reference driving values; and (e) between a color-dimming period and an adjacent compensating period, gradually switching the light-source module between the first color-dimming process and the full-color process.
