Problems solved by technology

[0007] However, the voltage is constantly applied to the backlight unit using CCFL, and the power consumption increases
One disadvantage of CCFL is that compared with cathode ray tube (CRT), its color reproduction rate is only about 70%, and another disadvantage is that it causes environmental pollution due to the addition of mercury

Embodiment Construction

[0045] Hereinafter, embodiments will be described with reference to the drawings.

[0046] It will be understood that when an element is referred to as being "on" or "under" another element, it can be directly on / under the other element, but one or more intervening elements may also be present.

[0047] When an element is referred to as being "on" or "under", this can include "under the element" as well as "on the element", based on the element.

[0048] figure 1 is a sectional view showing a backlight unit according to an embodiment.

[0049] Such as figure 1 As shown, the backlight unit may include a light source module 100 , a first reflector 200 and a second reflector 300 .

[0050] Here, the light source module 100 may be located between the first reflector 200 and the second reflector 300 . Here, the light source module 100 may be adjacent to the first reflector 200 .

[0051] In some cases, the light source module 100 may be spaced apart from the second reflector 3...

Abstract

Disclosed are a backlight unit and a display device using the same. The backlight unit includes a first reflector, a second reflector (300) and at least one light source module (100) disposed between the first and second reflectors, wherein a back surface of the first reflector comprises an inclined plane (201) and a flat surface (202), with facing the second reflector, and the inclined plane is adjacent to the light source and the flat surface is extended from an end of the inclined plane, with the inclined plane and the flat surface being collinear.

Description

technical field [0001] The invention relates to a backlight unit and a display device. Background technique [0002] In general, conventional display devices may include liquid crystal displays (LCDs), plasma display panels (PDPs), and the like. [0003] Unlike self-illuminating PDPs, LCDs are not self-illuminating, and require a backlight unit as a self-illuminating body. [0004] Such a backlight unit used in an LCD may be classified into an edge type backlight unit and a direct type backlight unit based on the position of a light source. In the edge type backlight unit, light sources are disposed on left and right lateral surfaces or upper and lower lateral surfaces of the LCD panel. Light can be uniformly dispersed to the front surface by the light guide plate. Therefore, the edge type backlight unit has good light uniformity and can make the panel ultra-thin. [0005] Direct-lit backlight units are used for monitors 20 inches or larger. In a direct type backlight u...
