1. Field of the Invention
The invention is related to a display panel, and more particularly to an ultra-thin backlight display panel.
2. Description of the Prior Art
Basically, traditional advertisement boards use fluorescent tubes as light sources to enhance their surface illumination. However, the fluorescent tubes have high-energy consumption and short lifetime. Besides, because the prior art advertisement boards must be large enough to install the fluorescent tubes, the thickness and the volume of the prior art advertisement boards could not be decreased easily. Therefore, the prior art advertisement boards have heavy and thick appearances and are not beautiful and fashionable at all.
