Therefore, if having with input media (as finger or pen) contact top electrode last transparent substrates certain a bit, the top electrode of then going up transparent substrates is electrically connected with the bottom electrode of following transparent substrates.Then, be output, then detect the position coordinates of contact according to output voltage with the resistance value of contact or the magnitude of voltage of capacitance variation.
Because common touch panel is bigger than display device, any problem can not appear in the process of making above-mentioned common touch panel.Simultaneously, in the LCD integrated touch panels, the size of touch panel is adjusted to the size of LCD, makes the idle space district of touch panel less than the liquid crystal edge of LCD.In this, the LCD integrated touch panels can cause the problem of making in the procedure of processing.
Describe below in conjunction with the prior art of accompanying drawing integrated touch panels.
Fig. 1 is the planimetric map of the LCD integrated touch panels of expression prior art.Fig. 2 is the sectional view of the LCD integrated touch panels of expression prior art along the I-I ' line among Fig. 1.Fig. 3 is the sectional view of the LCD integrated touch panels of expression prior art along the II-II ' line among Fig. 1.Fig. 4 is the sectional view of the LCD integrated touch panels of expression prior art along the III line among Fig. 1.Fig. 5 A is the design drawing of the last substrate of LCD integrated touch panels in the prior art.Fig. 5 B is the design drawing of the following substrate of LCD integrated touch panels in the prior art.
As mentioned above, in the LCD of prior art integrated touch panels, touch panel forms on the display surface of display device, and is used as the device of input signal on the display surface.
As shown in Figure 1, LCD integrated touch panels of the prior art comprises that one is observed district V/A and an idle space district 20.
At this moment, it is consistent with the display surface of display device to observe the district, and the idle space district forms at the periphery of observing the district, around observing the district.Then, upper and lower transparent substrates is connected with each other in idle space district 20 by a kind of insulated enclosure agent.
Therefore, the polyethylene terephthalate (PET) of the rectangle type consistent with display surface down substrate 2, go up substrate 1 toward each other, transparency electrode 3 and 4 forms on each inside surface of PET substrate 2 and last PET substrate 1 down respectively then.Then, the upper and lower PET substrate 2 and 1 of rectangle type couples together in idle space district 20 by sealant.
That is, if certain that goes up substrate a bit by pen or finger touch, transparency electrode 3 and 4 are electrically connected to each other at this point, feasiblely are output with the resistance of contact or the magnitude of voltage of capacitance variations.In order to read magnitude of voltage, there is a signal line to link to each other, so that voltage is imposed on transparency electrode and read the magnitude of voltage that changes with the contact with transparency electrode with the resistance value or the capacitance variation of this point.
At this moment, the transparency electrode in signal wire and the idle space district 20 links to each other.
To describe touch panel of the prior art in conjunction with sectional view.
Shown in Fig. 2 to Fig. 5 A and Fig. 5 B, the size and dimension of following substrate 2 and last substrate 1 is consistent with the display surface of display device.Then, transparency electrode 3 and 4 following substrate 2, on each inboard formation of substrate 1.At this moment, following substrate 2 and last substrate 1 are made by the material with elasticity and transparency (as PET).

Shown in Fig. 5 B, metal electrode 6a and 6b form in the idle space district 20 of the downside that descends substrate, upside, so that link to each other with transparency electrode 4.Then, form in the idle space district in the left side of following substrate from metal electrode 6a and the extended metal electrode 6c of 6b, so that metal wire 6a is linked to each other with FPC7 with 6b.At this moment, form insulation course 10b between transparency electrode 4 and the metal electrode 6c metal electrode 6 is not electrically connected with transparency electrode 4 with the identical mode of the metal electrode 5c of last substrate.
By metal electrode 6c, in idle space district 20, link to each other with 6b with metal electrode 6a as the FPC7 of signal wire.That is, on the upper and lower surface of FPC7, printed two signal line respectively, and FPC links to each other with 8b by conductive seal agent 8a with 6c with metal electrode 5a, 5c.
At this moment, two signal line that are printed on the upper surface of FPC7 link to each other with metal electrode 5c respectively, and two signal line that are printed on the lower surface of FPC7 link to each other with metal electrode 6c respectively.
As mentioned above, FPC7 links to each other with 8b by conductive seal agent 8a with 6c with metal electrode 5a, 5c, and upper and lower substrate is connected with each other by the idle space district of insulated enclosure agent 9 beyond in the FPC7 zone.
Below FPC7 is elaborated with the method that metal electrode 5a links to each other with 5b.
At first, conductive seal agent 8a and 8b are deposited on metal electrode 5a, the 5c and 6c that FPC will be connected, and insulated enclosure agent 9 is deposited in the idle space district 20 beyond the FPC7.Then, only heat the position (position of conductive seal agent deposit) that FPC7 will connect with 100 temperature of spending, and from this position of external compression, thereby FPC7 and metal electrode are coupled together.That is, upper and lower substrate is connected with each other.
Operation to touch panel describes below.
If a bit by pen or finger contact, following substrate and last substrate 3 and 4 are electrically connected at this point certain of last substrate surface.
At this moment, by two signal line and metal electrode 5a, 5b and the 5c that form on the FPC7 upper surface, power source voltage Vcc and ground voltage GND are applied in right side and the left side to the transparency electrode 3 on the last substrate 1.Then, by the metal electrode 6a of transparency electrode 4, following substrate 2,6b and 6c, and the signal wire that forms on the lower surface of FPC7 are read out with the resistance value of contact or the magnitude of voltage of capacitance variation, and the coordinate of X-axis is confirmed.
By two signal line on the upper surface that is printed on FPC7 and metal electrode 6a, 6b and 6c, power source voltage Vcc and ground voltage GND are applied in to the downside and the upside that are printed on down the transparency electrode 4 on the substrate 2.Then, by the metal electrode 5a of transparency electrode and last substrate 1,5b and 5c read this certain any magnitude of voltage, make that the coordinate of Y-axis is confirmed, thereby read XY axial coordinate value.
But the method for the structure of touch panel of the prior art and this type of touch panel of making has following problems.
At first, when FPC linked to each other by the conductive seal agent with metal electrode, FPC was made conductive seal agent fusing and inflow observe the district, thereby causes the defective of observing the district by the temperature heating with 100 degree.
