    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： In a method for driving a light source, a backlight assembly for performing the method and a display apparatus having the backlight assembly, a light source is driven by an initial power until a first time when initial brightness of the light source decreases to a reference brightness. Then, the light source is driven by a first compensation power after the first time, so that the light source has first compensation brightness. When the brightness of the light source decreases to the reference brightness, a driving power applied to the light source is changed to compensate the brightness of the light source. Thus, the light source is driven to have uniform brightness over an extended length of time.

    摘要： A light generating device includes a circuit board and a plurality of light source units. Each of the light source units includes a first light source group and a second light source group. The first light source group includes at least two light sources spaced apart from each other by a first distance and the second light source group including at least two light sources. Each of the light sources of the second light source group is spaced apart from a first virtual line segment connecting centers of the light sources of the first light source group by a second distance that is larger than the first distance. A second virtual line segment connecting centers of the light sources of the second light source group crosses the first virtual line segment. Therefore, a number of light sources is reduced to lower a cost of manufacturing the light generating device
