Abstract

A method for assembling a liquid crystal display includes steps of disposing a liquid crystal panel and a backlight module and blowing an ionic flow into the space between the liquid crystal panel and the backlight module to clean the surfaces of them. In addition, the method can be proceeded by an apparatus for assembling the liquid crystal display. The apparatus comprises a fastening device, a hoist platform, and an ionic particle-removal device. The fastening device has several vacuum suckers used to attach the surface of a liquid crystal panel and the panel is held and fixed. The hoist platform is disposed vertically under the fastening device to carry a backlight module and thus to adjust the distance between the liquid crystal panel and the backlight module. The ionic particle-removal device, which is disposed at a lateral part of the hoist platform and the fastening device, is capable of blowing an ionic flow to remove the particles and electrostatic charges attached on the surface of the liquid crystal panel and the backlight module simultaneously during assembly.

Claims

1. A method for assembling process of fitting a liquid crystal panel and a backlight module together, comprising:

fastening respectively the liquid crystal panel and the backlight module;

injecting an ionic flow in between the liquid crystal panel and the backlight module;

disposing the liquid crystal panel just above the backlight module; and

fitting the liquid crystal panel and the backlight module together.

2. The method of claim 1 wherein the protective films attached in between the backlight module and the liquid crystal panel are peeled off in advance before the backlight module is fastened.

3. The method of claim 1 wherein the ionic flow continuously injects in between the liquid crystal panel and the backlight module in advance before the liquid crystal panel is held on the backlight module in stack.

4. The method of claim 1 wherein the ionic flow continuously injects in between the liquid crystal panel and the backlight module in advance before the liquid crystal panel is held on the backlight module in stack. Furthermore, after a period of time has passed, the liquid crystal panel is then stacked on the backlight module.

5. The method of claim 1 wherein the direction of injecting the ionic flow to the surface of the backlight module is by a slanting angle while the ionic flow injects in between the liquid crystal panel and the backlight module.

6. The method of claim 1 wherein the gap between the liquid crystal panel and the backlight module is ranged from about 10 mm to 25 mm.

7. The method of claim 1 wherein the gap between the liquid crystal panel and the backlight module is about 10 mm.
