摘要： A backlight unit for a dynamic image and a display employing the same are provided. The backlight unit is used for a light source of a display and includes light-emitting devices (15) located separately on a substrate (20), an image analyzer which analyzes an image signal and extracts position information on a region requiring the relative increase or decrease of brightness, and a control unit (18) which independently drives and controls the light-emitting devices (15) located in a region corresponding to the position information inputted from the image board. Accordingly, the display employing the backlight unit can provide a more dynamic and realistic image.

摘要： A light emitting diode unit (15) includes a plurality of light emitting elements (5) for generating light of at least two different wavelengths and a cap (10) arranged to totally internally reflect the light emitted from the light emitting elements (5). The light from the light emitting elements (5) is mixed by undergoing multiple total internal reflections before exiting the cap (10). As this mixing is performed within the light emitting diode unit (15), the distance (d) between the light emitting diode unit (15) and other optical elements of the backlight unit (100), such as a diffusing sheet (40) can be reduced when compared with prior art arrangements. This can result in a backlight unit (100) and display device (200) having a relatively slim configuration. The light emitting elements (5) are preferably arranged on a base (7), at its periphery rather than its centre, in order to reduce the occurrence of hotspots.
摘要翻译：发光二极管单元（15）包括用于产生至少两种不同波长的光的多个发光元件（5）和布置成全部内反射从发光元件（5）发射的光的帽（10）。来自发光元件（5）的光通过在离开盖（10）之前进行多次全内反射来混合。由于在发光二极管单元（15）内进行混合，发光二极管单元（15）与背光单元（100）的其他光学元件（例如漫射片）之间的距离（d）可以与现有技术的布置相比减小。这可以导致背光单元（100）和具有相对纤细结构的显示装置（200）。发光元件（5）优选地在其周边而不是其中心处布置在基座（7）上，以便减少热点的发生。
