Problems solved by technology

As a result, the backlight assembly cannot sufficiently dissipate the heat generated by the lamp, so that the internal temperature of the backlight assembly gradually rises
[0004] Corresponding to the increase in internal temperature, the pressure of mercury injected into the lamp increases, thereby reducing the brightness of the backlight assembly
In addition, due to the uneven internal temperature, the injection distribution of mercury cannot be maintained uniformly, thereby deteriorating the display quality of the liquid crystal display

Embodiment Construction

[0027] Hereinafter, exemplary embodiments of the present invention are explained in detail with reference to the accompanying drawings.

[0028] figure 1 is an exploded perspective view showing a backlight assembly according to an exemplary embodiment of the present invention;

[0029] refer to figure 1 , the backlight assembly 100 includes a bottom frame 110 , a reflective plate 120 , a lamp 130 , a lamp guide and a radiation spacer 150 .

[0030] The bottom frame 110 has a bottom plate and side walls extending from the bottom plate to provide a receiving space. Accordingly, the bottom frame 110 is a receiving container for receiving the lamp 130 and the reflective plate 120 . An inverter 115 is disposed on a surface of the bottom plate of the bottom frame 110 opposite to the reflection plate 120 . In other words, the inverter 115 is disposed on the outer surface of the bottom frame 110 .

[0031] The reflective plate 120 is disposed in the accommodation space of the bot...

Abstract

In a radiant pad, a backlight assembly and a display device, the backlight assembly has a light source, a receiving container and a heat absorbing member. The receiving container receives the light source and the heat absorbing member to absorb radiant heat emitted by the light source. The backlight assembly further includes a discharge member disposed at an exterior surface of the receiving container to discharge heat from the light source transmitted through the receiving container. Accordingly, a temperature of the backlight assembly is lowered and a temperature difference between left and right areas of the backlight assembly is also reduced, thereby improving brightness properties.

Description

technical field [0001] The present invention relates to a backlight assembly and a display with the backlight assembly. More specifically, the present invention relates to a radiation spacer for a display capable of improving heat dissipation efficiency, a backlight assembly and a flat panel display having the backlight assembly. Background technique [0002] In a large-sized liquid crystal display, a direct illumination type backlight assembly is used to improve brightness performance. A large-sized liquid crystal display having a size exceeding 20 inches employs a direct illumination type backlight assembly having a lamp number of about 20 to about 50 units. [0003] In order to prevent the entry of foreign substances, the backlight assembly is almost completely isolated from the external environment. As a result, the backlight assembly cannot sufficiently dissipate the heat generated by the lamp, so that the internal temperature of the backlight assembly gradually rises...
