[0037] 图 3为本发明的实施例三， 其中， 如图 3所示： 背光源 2与显示装置分离， 其中 ， 该背光源可以为 LED、 CCFL灯、 荧光灯、 卤素灯、 UHP超高压汞灯、 激光灯 、 白炽灯构成的射灯、 灯条、 灯管、 面板灯等。 白天光线充足吋， 背光源 2关闭 或者打幵， 环境光通过可透光底壳照亮液晶面板 1显示画面； 晚上或者环境光亮 度不够吋， 打幵背光源 2， 照亮液晶面板显示画面。 背光源 2在可透光底壳 3之后 ， 背光源 2发光通过可透光底壳 3透射照亮液晶面板 1显示画面。 本发明中底壳采 用透明玻璃或者透明亚克力， 白天就可以成为一种户外透明显示装置。
[0038] 综上所述， 以上仅为本发明的较佳实施例而已， 并非用于限定本发明的保护范
围。 凡在本发明的精神和原则之内所做的任何修改， 等同替换， 改进等， 均应 包含在本发明的保护范围内。
