Assembly structure and method of display device

Abstract

The invention discloses an assembly structure and an assembly method of a display device, which are used for assembling a liquid crystal display panel and a backlight module. The assembly structure comprises a bench and at least three positioning post. The bench has a first groove for holding the backlight module; and the positioning posts are arranged on at least two adjacent sides of the first groove for positioning the liquid crystal display panel when the liquid crystal display panel is placed on the backlight module, and the positioning posts are tangent to the edge of the liquid crystaldisplay panel. The assembly structure and the assembly method of the invention can be used for detecting the surface foreign material condition of the backlight module after the backlight module is placed in the assembly structure and sticking the foreign matters; and assembly precision can be ensured with the positioning posts limiting the sizes of spacing between the liquid crystal display panel and the backlight module.

Description

technical field [0001] The present invention relates to an assembly structure and an assembly method, in particular to an assembly structure and an assembly method of a liquid crystal display panel and a backlight module. Background technique [0002] In the prior art, the assembly process of the liquid crystal display panel and the backlight module of the display device is as follows. First, prepare the liquid crystal display panel: tear off the protective film of the lower polarizer on the liquid crystal display panel (Panel); put the liquid crystal display panel on the Panel machine. Prepare the backlight module: tear off the protective film of the backlight module (BL); put the backlight module on the BL machine. Next, use the suction nozzle to pick up the liquid crystal display panel, and use the image capture unit (CCD) to grab the positioning edge of the liquid crystal display panel; use the suction nozzle to move the liquid crystal display panel to the BL machine an...

Problems solved by technology

[0003] However, in the assembly process of the above-mentioned liquid crystal display panel and backlight module, there are many processes that are easy to bring in impurities or particles, such as the action of placing the Panel and BL on the machine and the action of sucking the Panel with the suction nozzle; and At present, it is inconvenient to clean the internal mechanism of the machine assembly. It is impossible to overcome the foreign matter brought in during assembly by simply wiping the machine and the incoming materials of the LCD panel / backlight module.
