液晶显示器及其背光模块 Liquid crystal display and a backlight module

技术领城 Technical collar city

本发明涉及一种液晶显示器及其背光模块,特别是涉及一种直下式液晶背光模块,其可有效地增强热对流而达到灯管录佳发光效率。 The present invention relates to a liquid crystal display and a backlight module, particularly to a direct backlight type liquid crystal module, which may be effective to enhance the convective heat to reach good recording lamp light emission efficiency.

背景技术 Background technique

一般液晶显示器中的背光模块系用来提供所需的光源,由于目前背光模块尺寸越来越大,直下式背光模块所需的辉度也不断提高,而荧光灯管的数量及供给电力也必须提高,然而,这将使得灯管周围环境温度升高,而导致即使增加了荧光灯管的数量及供给电力,却无法增加辉度的情况。 In the general liquid crystal display backlight module to provide a desired source lines, the current increasing size backlight module, a direct type backlight module desired luminance is also rising, while the number of fluorescent tubes and the supply of power must also increase However, this will cause the lamp ambient temperature increases, even if the resulting increase in the number of fluorescent tube and power supply, but can not increase the luminance of the case. 详而言之, 由于背光模块内的温度过高,使得其辉度反而会随着操作时间的增加而降低,造成灯管辉度下降的问题。 Specifically speaking, since the high temperature inside the backlight module, but such that the luminance increases as the operation time decreases, causing problems of decrease of the lamp brightness.

因此, 一般背光模块使用铝背板来作为主要散热机制,如图1所示,背光模块10包括一反射板(reflectorsheet)ll、 一光扩散板16、光学薄膜层17a、 17b、多个荧光灯管13及一铝背板15。 Thus, generally the backlight module backplane using aluminum as the main mechanism for heat dissipation, shown in Figure 1, a backlight module 10 comprises a reflector plate (reflectorsheet) ll, a light diffusion plate 16, the optical thin film layers 17a, 17b, a plurality of fluorescent tubes 13 and a back plate 15 of aluminum. 其中,光扩散板16以包覆荧光灯管13的方式设置于反射板ll上,荧光灯管13作为背光模块10的光源,且设置于一支撑部(未显示),反射板11位于铝背板15的上方,用以将荧光灯管13的光反射出背光模块10,而铝背板15位于背光模块10的底部,用以传递热量到外界。 Wherein an optical diffusing plate 16 to cover the fluorescent tube 13 is disposed on the reflective plate ll, fluorescent tube 13 as the light source of the backlight module 10, and is disposed on a support (not shown), the reflecting plate 11 is located an aluminum backplate 15 above for the fluorescent tube light reflected off of the backlight module 13, 10, 15 and the aluminum backplate 10 is located at the bottom of the backlight module, to transfer heat to the outside.

然而,由于目前直下式背光模块设计中通常搭配反射板来反射光源,所以反射板的存在使得热量并非直接传递到铝背板,而是通过反射板再间接传递到铝背板上,也正因为如此将使得背光模块内部的热量无法快速的传递外界,造成灯管周围环境温度升高,使得灯管的辉度下降。 However, the current design of a direct type backlight module is generally used with a reflective plate for reflecting light, there is a reflective plate so that heat is not directly transferred to an aluminum backing plate, but indirectly through the reflecting plate and then transferred to an aluminum back plate, because of so that the heat inside the backlight module can not be quickly passed outside, causing environmental temperature around the lamp so that the lamp brightness decreases.

因此,如何有效克服背光模块热的问题,且有效提高背光模块的光学效率,是目前必须积极解决的问趙之一,使得灯管的发光效率达到最佳化。 Therefore, how to overcome the problem of heat backlight module, and effectively improve the optical efficiency of the backlight module, is a positive solution must ask one of Zhao, so that the luminous efficiency of the lamp to optimize.
