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： 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.

摘要： In accordance with embodiments of the present disclosure, a backlight unit assembly is provided with a lamp and a light emitting diode (LED) periodically turned on and off, and a liquid crystal display having the backlight unit assembly. A light source is configured with both the lamp and the LED, and the LED is periodically turned on and off by applying a start signal, which are capable of removing image sticking on a liquid crystal display (LCD) panel. This feature may reduce power consumption and increase contrast ratio. The backlight unit assembly and the LCD are capable of adjusting a chromaticity coordinate of the light source to a reference chromaticity coordinate.
