Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding device for folding a flexible circuit board,

The present invention relates to a flexible circuit board folding apparatus, and more particularly, to a flexible circuit board folding apparatus capable of preventing a failure occurring when a touch circuit board and a display circuit board are disposed adjacent to each other in folding a display circuit board And more particularly, to a flexible circuit board folding apparatus of a touch-type display apparatus and a flexible circuit board folding method using the same.

2. Description of the Related Art In recent years, as portable electronic devices such as a mobile phone, a PDA, and a notebook computer have developed and counter electronic devices have been developed, the demand for a thin flat panel display device is gradually increasing. As such flat panel display devices, a liquid crystal display (LCD), a plasma display panel (PDP), a field emission display (FED), and an organic light emitting diode display (OLED) have been actively studied.

On the other hand, personal computers, portable communication devices, and other personal-purpose information processing devices generally have an interface with a user by using various input devices such as a keyboard, a mouse, and a digitizer. However, as the development of portable electronic devices has expanded, input devices such as a keyboard and a mouse can not be input to a portable electronic device, and a touch panel (Touch Panel) was proposed.

The touch panel is a resistive type in which a metal electrode is formed on a top plate or a bottom plate in accordance with a method of detecting a contact portion to detect a current change according to a resistance in a contact position in a state where a DC voltage is applied, (Capacitive type) which detects the position where the voltage change of the upper and lower plates due to the contact is formed, and an electrostatic capacity type sensor which reads the LC value induced by the contact of the electronic pen with the conductive film and detects the contact position And an electro magnetic type.

Such a touch panel can be attached to the upper surface of the display panel of the flat panel display device or can be formed directly in the display panel, and the touch-type display device including the touch panel is convenient to use, And has recently been applied to various information processing apparatuses.

2 is a cross-sectional view taken along a line II-II 'in FIG. 1, and FIG. 3 is a cross-sectional view illustrating a process of folding a display circuit board in the touch- Fig.

Referring to FIGS. 1 and 2, a conventional touch-type display device 1 includes a display panel 10 for displaying an image, a touch panel 10 for sensing a touched position when a user touches a predetermined area, And a driving circuit for driving the panel 20 and the display panel 10 and the touch panel 20, respectively.

The display panel 10 and the touch panel 20 are bonded to each other by an adhesive layer (not shown). In addition, although not shown in the drawing, tempered glass (not shown) is disposed on the upper surface of the touch panel 20 to prevent breakage of the touch panel 20 due to an external impact.

The driving circuit unit includes a display circuit board 15 bonded to one side of the display panel 10 to control the driving of the display panel 10 and a display circuit board 15 connected to one side of the touch panel 20 to control the driving of the touch panel 20 And a touch circuit board (25). The display circuit board 15 and the touch circuit board 25 are formed of a flexible printed circuit board (FPCB) and are positioned adjacent to each other at one side of the display panel 10 and the touch panel 20 .

Driving chips 16 and 26 for driving are located above the substrates of the display circuit board 15 and the touch circuit board 25, respectively. That is, on the upper surface of the touch circuit board 25, a touch driving chip 16 for controlling the driving of the touch panel 20 is positioned. On the upper surface of the display circuit board 15, the driving of the display panel 10 is controlled The driving chip 26 for display is located.

Here, the display circuit board 15 is bent and disposed on the back surface of the display panel 10. 3, a process of folding the display circuit board 15 to the backside of the display panel 10 is performed.

However, since the display circuit board 15 and the touch circuit board 25 are adjacent to each other as described above, in order to fold the display circuit board 15 to the back surface of the display panel 10, Work is required.

Conventionally, the operator has manually separated the display circuit board 15 and the touch circuit board 25 from each other, but this causes a lot of defects.

For example, the operator pulls the display circuit board 15 in the direction of the back of the display panel 10 while holding the display circuit board 15 by hand, separates the two circuit boards, and then attaches the display circuit board 15 to the display panel 10 The process of attaching to the back surface is performed manually. At this time, if the operator forcibly pulls the display circuit board 15, a crack or the like is generated in the display circuit board 15 as shown in FIG. 3A. This causes a malfunction of the touch-type display device 1. [

For example, the position recognition unit 320 may include an image pickup device using a sensor such as a CCD (Charge-Coupled Device), a CMOS (Complementary Metal-Oxide Semiconductor) . The position recognition unit 320 can photograph the side surfaces of the first circuit board 15 and the second circuit board 25 and detect the positions of the ends of the first circuit board 15 and the second circuit board 25, respectively.

The end position information of the first circuit board 15 and the second circuit board 25 detected by the position recognizing unit 320 may be provided to a controller 370 to be described later. The control unit 370 can control the operation of the substrate separating unit 335 and the folding unit 360 based on the end position information.
