摘要： An optical member according to one or more embodiments includes an optical plate and an optical film. In an embodiment, the optical plate includes an incident part receiving light provided from the exterior and an emitting part emitting the light. The optical film is attached to the incident part and includes a first conductive layer, a second conductive layer facing the first conductive layer and polarized particles disposed between the first conductive layer and the second conductive layer. Thus, light sources of a backlight assembly may be individually driven regardless of the type of light source and the disposition of the light sources, and image display quality may be improved by improving a contrast ratio by realizing various gradation voltages.

摘要： A backlight assembly including direct-type lamps and an edge-type lamp and a liquid crystal display having the backlight assembly. The direct-type lamps are arranged with a predetermined interval to emit light, and the edge-type lamp is provided at a side portion of a light guide plate provided above or below the direct-type lamps. The light guide plate and a light guide pattern output light, which is emitted from the edge-type lamp, through a space between two adjacent direct-type lamps. The backlight assembly supplies light to the light receiving region such that brightness is uniformly distributed throughout the light receiving region regardless of the position of the direct-type lamps.

摘要： A plurality of point-light sources emits light, based on an image displayed on a display panel. A substrate has the point-light sources disposed thereon. A power-controlling section provides the point-light sources with first driving current having a pulse current with a pulse modulation duty less than or equal to a maximum pulse modulation duty cycle and a first amplitude in accordance with a normal image. A power-controlling section provides the point-light sources with second driving current having a pulse current with the maximum pulse modulation duty cycle and first boosting amplitude greater than the first amplitude in accordance with a high luminance image. Thus, the quantity of emitted light of the point-light sources may be adjusted in accordance with the position of an image displayed in a display panel, and the point-light sources that correspond to high luminance images may be boosted up.

摘要： In a method of driving a light source, light generated by a light source is sensed in order to detect color coordinates of a red color, color coordinates of a green color and color coordinates of a blue color. A light source color space formed by the color coordinates of the red, green and blue colors is compared with a reference color space formed by red reference color coordinates, green reference color coordinates and blue reference color coordinates. Then, color temperature of the light generated by the light source is controlled so that the light source color space covers the reference color space.
