Description

Flat panel attachment device and method {FLAT PANELS BONDING APPARATUS AND METHOD}

The present invention relates to a flat panel attachment, wherein the first flat panel and the second flat plate are prevented from leaking UV-curable solvent between the first flat panel and the second flat panel when the first flat panel and the second flat panel are attached to each other. The present invention relates to a flat panel attachment apparatus and method capable of attaching a panel precisely.

Generally, a liquid crystal display includes a liquid crystal panel in which liquid crystal is injected between two display panels, a backlight assembly including a light source and a light guide plate for supplying a constant backlight to the liquid crystal panel, and receives an image signal input from the outside. It is a display device to display.

In such a liquid crystal display, a digitizer for displaying an image and inputting an electric graphic signal on a displayed screen is mounted. Such a device is called an EGIP (Electric Graphic Input Panel) or a touch screen panel.

The touch screen panel is a peripheral device installed on the display surface of the liquid crystal display device and presses the touch screen panel while the user views the liquid crystal display device to input predetermined information into the computer. Generates a current signal and enters user-specified command or graphic information.

The front of the touch screen panel, which is a kind of flat panel, is attached with a window that protects the panel and prints the necessary text or pattern. The window is made of transparent plastic or the like.

As a conventional method for attaching a touch screen panel and a window, an optical clear adhesive (OCA) film may be used.

However, the conventional method of attaching the touch screen panel and the window to each other via the OCA film has a problem in that bubbles are generated on the adhesion surface of the window and the OCA film due to a step caused by the printing layer of the window or the like.

In order to solve this problem, a method of attaching a touch screen panel and a window by applying an ultraviolet curable solvent (UV solvent) to a touch screen panel or a window surface instead of an OCA film and curing it is recently used.

In the conventional method, after applying the UV curable solvent between the touch screen panel and the window, the touch screen panel and the window are pressed using a squeeze, and after pressing the touch screen panel and the window, the UV curable solvent is cured by irradiating ultraviolet rays. Let's do it.

However, in the conventional method, since the touch screen panel and the window are crimped using a squeeze, it is difficult to control the pressure of the touch screen panel and the window, so that the UV-curable solvent protrudes outward from the touch screen panel and the window and hardens. .

When pressure is applied when pressing the touch screen panel and the window in this way, the UV-curable solvent hardens out of the space between the touch screen panel and the window, resulting in product defects, or the portion hardened out of the space between the touch screen panel and the window. Since post-processing is required to remove the product, it has been a cause of lowering productivity.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the ultraviolet-curable solvent applied between the first flat panel and the second flat panel can be adjusted so that the pressing force applied to the first flat panel and the second flat panel can be adjusted appropriately.
