[ background of the invention ]

Liquid crystal displays, which are flat, ultra-thin display devices, consist of a certain number of color or black and white pixels placed in front of a light source or a reflective surface. Liquid crystal displays are very low power consuming and are therefore favored by engineers for use in battery-operated electronic devices. The main principle is that the current stimulates the liquid crystal molecules to generate points, lines and surfaces which are matched with the back lamp tube to form a picture.

However, most of the existing liquid crystal display screens adopt plastic frames, and the plastic frames cannot be made thinner due to lower strength, so that the thickness of the plastic frames is limited; liquid crystal display generally can be through the fix with screw on the strengthening rib, is connected frame and display screen backshell fixed, and the equipment is not only wasted time and energy to this mode, can increase liquid crystal display's thickness moreover, and sealed effect, some adoption tradition buckles replace the fix with screw, but receiving under the external force condition, the frame takes place to warp easily.

In view of the above, it is desirable to provide a narrow-bezel lcd panel connection structure to overcome the deficiencies of the prior art.
