Description

[0001] Bonding device for dual panel in which the contacts of two or more tags are superposed [

The present invention relates to a bonding apparatus for a dual panel in which contacts of at least two or more tags are overlapped.

2. Description of the Related Art Generally, a display device is a device for converting a signal output from a computer device (hereinafter referred to as "computer") such as a computer into an image and displaying the image signal. However, in recent years, a display device having an input function has been developed and used.

That is, in order to display a new image from a display device, a conventional display device requires a data input device such as a keyboard, a keypad, and a mouse for inputting information to a computer, but a display device recently developed and used requires information So that it can be input. As a representative example of such a display device, there is a touch screen having a touch panel as a position detection sensor on a display panel.

The touch panel includes a touch panel for detecting a position on a display panel for displaying an image. The touch panel is electrically connected to a main board on which a chip for driving the display panel is mounted. The touch panel includes a main circuit board And an auxiliary circuit board for transferring the touch position coordinate signal, which is glued and sensed, to the main board is attached. The auxiliary circuit board is fixed to the outermost portion of the display panel in the process of manufacturing the module of the display device.

The display panel includes various types such as LCD, OLED, and AMOLED, and various flexible and rigid ones according to physical properties. The touch screen using such a display panel includes a flexible circuit board (M-FPC (Hereinafter collectively referred to as "M-FPC") and a flexible circuit board (T-FPC, hereinafter collectively referred to as "T-FPC") extended from a touch panel. And transmits and receives electrical signals to each other to perform a display function and an input function.

In order to connect the M-FPC of the display panel and the T-FPC of the touch panel to each other, the connection tags are extended from the two FPCs and the contacts formed on the respective tags must be accurately aligned. In this case, when the tag contacts of two FPCs are not aligned correctly, there is a problem that accurate information can not be inputted.

Various techniques for bonding the contacts of the tags of the display panel M-FPC and the touch panel T-FPC have been developed, for example, Patent Documents 1 and 2.

The conventional method and apparatus for connecting the FPC tag contacts are separately supplied with the FPC and the panel separated from each other, bonding the FPC and the panel substrate to each other, bonding the FPCs to each other, .

However, in the conventional FPC bonding method, as described above, the FPC and the panel are respectively supplied and joined together. After supplying each of the display panels and the touch panel to which the FPC is bonded separately, The display panel M-FPC and the touch panel T-FPC tag contacts are aligned and pressed to align the contacts between the two FPC tags. However, in this method, The process of bonding the contacts of the FPC tag requires a long time, and the alignment of the contacts is not properly performed, thereby increasing the defect rate.
