图 7是本发明背光模组的第四实施方式的结构示意图。
【具体实施方式】
请一并参阅图 2和图 3 ,图 2是本发明液晶显示装置的较佳实施方式的结构 示意图, 图 3是本发明背光模组的第一实施方式的结构示意图。 液晶显示装置 2 包括显示面板 20、 塑件 22、 前框 24及背光模组 26。 显示面板 20设置在背光模 组 26上方, 前框 24与塑件 22相互配合以固定显示面板 20和背光模组 26。
背光模组 26包括光源 260、 导光板 262及背板 264。 导光板 262位于背板
264上方, 且导光板 262的入光面正对光源 260设置。
背板 264包括铝挤 265和塑料底板 266 ,光源 260设置在铝挤 265远离塑料 底板 266的一侧的侧壁 261上。 在此实施方式中, 光源 260焊接在铝挤 265的 侧壁 261上。
塑料底板 266与铝挤 265的一侧固定连接, 具体而言, 铝挤 265与塑料底 板 266设有多个固定孔 267 , 通过螺钉(图未示)穿过多个固定孔 267可将铝挤 265与塑料底板 266固定连接。 此外, 塑料底板 266也可由其他散热效果一般、 价格较低的材料代替。
由于光源 260直接设置在铝挤 265远离塑料底板 266的一侧的侧壁 261上, 光源 260所对应的背板部分为铝挤, 因此光源 260发出的热量可直接经过铝挤 265散发到空气中, 降低了光源 260和铝挤 265的接触热阻, 提高了背光模组 26的散热效率。 并且背板 264除了主要散热面为铝挤外, 其他部分由散热效果 一般但价格较低的塑料底板 266构成, 以减少价格相对昂贵的铝挤的使用量, 降低材料成本。
请参阅图 4 , 图 4是本发明背光模组的第二实施方式示意图。 背光模组包括 光源 360、 导光板 362及背板 364 , 背板 364包括铝挤 365和塑料底板 366。 本 发明背光模组的第二实施方式与前文所述的第一实施方式的区别在于: 本实施 方式中, 在铝挤 365远离塑料底板 366的一侧的底面上进一步设有中空部 368。 中空部 368具有散热鰭片 369 , 且中空部 368的两端贯通, 以形成热对流。
图 5是如图 4所示的背光模组同显示装置外壳装配后的立体结构示意图, 显示装置包括外壳 30和设置于外壳 30内的背光模组 (图未示)。 外壳 30在对 应中空部 368的位置设有贯通孔(图未示)。 由于背光模组的中空部 368两端贯 通, 其与显示装置外壳 30装配后可以在外壳 30两端形成独立的对流散热系统, 可进一步提高背光模组的散热效率。
请继续参阅图 6 , 图 6是本发明背光模组的第三实施方式示意图。 本实施方 式与图 4 所示的第二实施方式相比, 主要区别在于中空部设置的位置不同。 在
本实施方式中, 中空部 468 背向光源设置于光源所在侧壁的外侧。 当然, 只要 设计合理, 中空部可以设置在光源的其他位置。
前述的实施方式均以单侧入光的背光模组为例进行说明, 但是本发明并不 限于于此。
请参阅图 7所示, 图 7为本发明背光模组的第四实施方式的结构示意图。 本实施方式与图 3 所示的第一实施方式相比, 主要区别在于背光模组为双侧入 光模式, 铝挤 265包括第一铝挤 265a和第二铝挤 265b , 且第一铝挤 265a和第 二铝挤 265b的侧壁 261a和 261b上分别焊接光源 260。 塑料底板 266设置于第 一铝挤 265a和第二铝挤 265b之间, 且分别与第一铝挤 265a和第二铝挤 265b 远离光源 260的一侧通过固定孔 267以螺丝(图未示)固定连接。
在双侧入光的模式下, 在铝挤 265上也可进一步于光源 260的下方或后方 相应设置中空部, 以进一步提高散热效率。
综上所述, 本发明的显示装置及背光模组中, 以铝挤构成背光模组背板的 一部分, 且将光源直接整合到铝挤上, 因而光源产生的热可经铝挤直接传至大 气, 具有降低接触热阻, 提高散热效率的优点; 并且, 中空部的散热设计在背 光模组与显示装置外壳装配后可以形成独立的对流散热系统, 进一步提高了背 光模组的散热效率。 此外, 背板的主要散热区域设计为铝挤, 其余部分釆用散 热效果一般、 价格较低的塑料底板, 具有降低背板的材料成本的优点。
以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运 用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
