Problems solved by technology

[0007] However, the backlight unit using the CCFL has several disadvantages, such as: it consumes a lot of power because it always needs to apply power to the CCFL; its color reproduction efficiency is low, only about 70% of that of a cathode ray tube (CRT) and, due to the use of mercury, caused environmental pollution

Embodiment Construction

[0049] Hereinafter, embodiments will be described with reference to the drawings.

[0050] 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.

[0051] 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.

[0052] Figure 1A to Figure 1C is a view illustrating a backlight unit according to an embodiment, in which, Figure 1A is the cross-sectional view, Figure 1B is the top view, and Figure 1C is the top perspective view.

[0053] Such as Figure 1A to Figure 1C As shown, the backlight unit may include: a light source module 100, which includes a circuit board 120 and at least one light source 110; a first reflector 200; a second reflector 300; and a reflective structure 400, which includes a reflective structure part 410 and supp...

Abstract

Disclosed herein are a backlight unit and a display apparatus using the same. The backlight unit includes a first reflector, a second reflector partially having an inclined surface, at least one light source module disposed between the first and second reflectors, and at least one reflective structure disposed on the second reflector.

Description

technical field [0001] The invention relates to a backlight unit and a display device using the backlight unit. Background technique [0002] In general, examples of typical large display devices include liquid crystal displays (LCDs), plasma display panels (PDPs), and the like. [0003] Unlike self-illuminating PDFs, LCDs require a separate backlight unit due to the lack of self-emitting elements. [0004] Backlight units used in LCDs can be classified into edge-type backlight units and direct-type backlight units according to the position of a light source. In the edge type backlight unit, light sources are arranged on the left and right sides or the upper and lower sides of the LCD panel, and a light guide plate is provided to uniformly diffuse the light over the entire surface of the LCD panel, thereby ensuring uniform brightness and enabling Manufactures ultra-thin display panels. [0005] Direct-lit backlight units are generally suitable for displays larger than 20 ...
