Description

Touch screen panel manufacturing method

The present invention relates to the art of planar display devices, and more particularly to a method of fabricating a touch screen panel using a simplified process.

Generally, the touch screen device refers to a device that recognizes a coordinate value of a contact point when a user's finger or an object such as a stylus touches a specific position displayed on the screen, and the touch screen is equipped with the touch. The electronic device of the screen is controlled. Depending on the driving and sensing modes and the technology used, the touch screen device can have different types of screens, such as a capacitive touch screen, a resistive touch screen, a surface acoustic wave touch screen using infrared or ultrasonic waves, or the like.

The touch screen device comprises a display panel and a touch screen panel attached to the display panel. In addition, the touch screen panel comprises a transparent electrode layer formed by the sensing electrode pattern and a polarizing film on the transparent electrode layer.

FIG. 5 is a view showing a procedure for manufacturing a touch screen mother substrate by attaching a polarizing film mother substrate to the transparent electrode thin mother substrate in the method of manufacturing a touch screen panel according to the first embodiment of the present invention; Cross section view.

Referring to FIG. 5, a protective film 116 is deposited on a polarizer 114 to prepare a polarizing plate 118, and then formed in a position corresponding to the pad portion 25 of the touch panel 20 in the polarizing plate 118. The first-1 pad penetrates the portion 120 ((a) of Fig. 5). Here, the polarizing plate 118 has the same size as the touch screen panel mother substrate 10 shown in FIG. 1 . However, for convenience of description, the touch screen panel mother substrate 10 is illustrated as having a touch screen panel corresponding thereto. 20 sizes.

Fig. 6 is a plan view showing a state in which a penetrating portion is formed in a mother substrate of a polarizing plate. Referring to Fig. 6, a polarizing plate mother substrate 118' has the same dimensions as the touch screen panel mother substrate 10. Each of the first -1 pad penetration portions 120 is formed in the polarizing plate mother substrate 118' corresponding to the position of the pad portion 25 of each of the touch screen panels 20.

As described above, since the first-1 pad penetration portion 120 is first formed in the polarizing plate mother substrate 118', even if the polarizing plate mother substrate 118' is attached to the transparent electrode thin layer mother substrate 50, smoothing is possible. Follow up the process. Therefore, the entire manufacturing process can be simplified, and the production yield can be improved. That is, when the polarizing plate mother substrate 118' is attached to the transparent electrode thin layer mother substrate 50, the conductive layer 112 is exposed to the outside, and a flexible printed circuit board (FPCB) is thus connectable to the conductive layer 112, This makes it possible to carry out the subsequent procedures smoothly. The reason is detailed as in Fig. 7 and its description.

Referring to FIG. 5, a retardation film 122 is deposited on the transparent electrode thin layer mother substrate 50 to cover the second sensing pattern 106-2 and the conductive layer 112, and then corresponding to the pad portion in the retardation film 122.

Here, the retardation film 122 may include a photo alignment film and a 1/4 wavelength liquid crystal layer deposited on the photo alignment film. In this embodiment, the first - 2 pad penetration portion 124 formed in the retardation film 122 is used to be positioned at a position corresponding to the first - -1 pad penetration portion 120 formed in the polarizing plate 118. . The first --2 pad penetration portion 124 may be formed on the conductive layer 112 to expose a portion thereof to the outside.

Next, the polarizing plate 118 is attached to the retardation film 122 ((c) of Fig. 5). Here, the first -1 pad penetration portion formed in the polarizing plate 118 and the first - - 2 pad penetration portion 124 formed in the retardation film 122 form a first pad penetration portion 126. At this time, the conductive layer 112 is exposed to the outside through the first pad penetration portion 126. When the retardation film 122 is not required to be formed, the first-1 pad penetration portion 120 formed in the polarizing plate 118 inherently functions as the first pad penetration portion 126.

In addition, the polarizing plate 118 and the retardation film 122 form a polarizing film 128. The polarizing film 128 has a function of blocking external light reflection to improve visibility. In the fifth embodiment, although the polarizing film 128 includes the polarizing plate 118 and the retardation film 122, it is not limited thereto, and the polarizing film 132 may include only the polarizing plate 118 according to the form of the display panel.

Next, after the bottom member 102 is removed from the base film 104 ((d) of FIG. 5), an adhesive layer 130 and a release layer 132 are sequentially deposited on the lower surface of the base film 104 (Fig. 5 (e)).

Next, the touch screen panel mother substrate 10 is attached to a display panel mother substrate 70 ((b) of FIG. 7). In this example, after the release film 132 is removed from the base film 104, the touch screen panel mother substrate 10 is attached to the display panel mother substrate 70. The display panel mother substrate 70 includes a display pad portion 136 formed thereon and thus exposed to the outside through the second pad penetration portion 134. That is, the second pad penetration portion 134 and the display pad portion 136 are formed at positions corresponding to each other.

Then, the touch screen panel mother substrate 10 and the display panel mother substrate 70 are cut into individual touch screen sheets 90 having the same size as the touch screen panel 20 ((c) of FIG. 7).

Thereafter, a first flexible printed circuit board (FPCB) 138 and a second FPCB 140 are attached to each of the touch screen units 90 ((d) of FIG. 7). At this time, one end of the first FPCB 138 can be electrically connected to the conductive layer 112 exposed through the first pad penetration portion 126, and the other end of the first FPCB 138 can be connected to the touch screen. One of the panels of the IC chip (not illustrated). One end of the second FPCB 140 can be electrically connected to the display pad portion 136, which is exposed to the outside through the second pad penetration portion 134, and the other end of the second FPCB 140 can be connected to a driver ( Not illustrated) for driving the display panel. Here, after the protective film 116 is removed from the polarizer 114, the first and second FPCBs 138 and 140 may be located in the touch screen unit 90.

According to the first embodiment of the present invention, the first -1 pad penetration portion 120 may be first formed in the polarizing plate mother substrate 118', and the polarizing plate mother substrate 118' itself may be attached to the transparent electrode thin layer mother The substrate 50 is used to prepare the touch screen panel 20. Therefore, the number of attachment programs in the overall manufacturing process of the touch screen panel can be significantly reduced, and the overall production process can be simplified. For example, when twelve touch screen panels are prepared by a touch panel mother substrate, in the related art, the transparent electrode thin layer having the product unit size and the polarizing plate are attached to each other, so that twelve attachments must be performed. program. However, according to the first embodiment of the present invention, only one attachment process is required to attach the transparent electrode thin mother substrate 50 and the polarizing plate mother substrate 118', so that the number of attachment processes can be remarkably reduced and thus the overall production process can be simplified. In addition, since the second pad penetration portion 134 is formed in the touch screen panel 20, and the touch screen panel 20 is attached to the display panel mother substrate 70, the subsequent processing can be smoothed and further simplified. Overall production process.
