Description

  The present invention relates to a display device with a touch panel, and more particularly, to a display device with a touch panel including a touch panel capable of varying a detection resolution on a detection area of the touch panel.

As a main method of a conventional touch panel, there are a method for detecting a change in light and a method for detecting a change in electrical characteristics. Among these, the method of detecting a change in light has a problem that the detection accuracy is not stable.
Conventionally, there are a resistance film method and a capacitance method as a method for detecting a change in electrical characteristics. FIG. 12 shows a cross-sectional structure of a conventional resistive film type touch panel.
As shown in FIG. 12, a transparent electrode (TLINE) covering the entire detection region is formed on a glass substrate (GSUB), and on the other side, a transparent electrode (TLINE) is also formed on a light-transmissive resin film (RESIN). It has a structure in which a film is formed and bonded so as to face a transparent electrode on a glass substrate (GSUB). A transparent spacer (SPACER) is installed in the surface so that each transparent electrode (TLINE) does not short-circuit, and a certain interval (several to several tens of μm) is maintained.
In this resistive film method, since the transparent electrode has a high resistance, the input point, that is, the contact position of the upper and lower transparent electrodes is detected in a one-dimensional manner using the potential difference of the voltage applied to the transparent electrode. Two-dimensional coordinates are calculated by performing voltage application and potential difference detection twice with the X and Y axes.

However, this resistive film system has the following problems (A) to (K).
(A) Since the operation mechanism of the resistance film system is an application of high resistance characteristics due to the fact that the transparent electrode is a metal oxide, in the case of a low resistance film, the voltage drop is reduced and detection becomes impossible.
(B) If multiple points are input simultaneously, normal detection is impossible.
(C) Cost is required for patterning and film formation of the transparent electrode.
(D) Since the voltage drop needs to be detected in analog, the cost of the circuit is high.
(E) The cost of the flexible cable which connects a transparent conductive film and a circuit is high.
(F) There is a problem of reliability such as instability of the transparent conductive film due to the metal oxide, for example, damage due to stress during operation of the touch panel, and resistance deterioration due to current flowing through the transparent conductive film.
(G) Since the transparent conductive film has high resistance, it is difficult to increase the size, and the practical size limit is considered to be 17 inches (about 200 × 300 mm).
In view of these problems, the present applicant has already proposed a touch panel that employs a new detection structure. (See Patent Document 1 below)

[Overview of touch panel as a premise of the present invention]
FIG. 13 is a schematic plan view of a touch panel as a premise of the present invention. FIG. 13 is the same as the touch panel described in Patent Document 1 described above.
The touch panel shown in FIG. 13 includes a first substrate (SUB1) and a second substrate (SUB2) having a resin film made of PET (PolyEthylene Terephthalate), a first peripheral circuit (SC1), and a second substrate. A peripheral circuit (SC2), a power supply, and a detection signal output terminal are provided.
The first substrate (SUB1) and the second substrate (SUB2) are made by bonding the copper foil, which has been reduced to 10 μm or less by cold rolling, with PET film and decorative steel plate technology, and then jetting the etching solution at high temperature and high pressure. This is a flexible wiring board in which a metal wiring processed to have a taper angle of 80 to 90 degrees by an etching technique is processed into a stripe shape.
The metal wirings of the first substrate (SUB1) and the second substrate (SUB2) are arranged so that the metal wirings face each other and the extending directions of the metal wirings intersect each other.
The first peripheral circuit (SC1) is connected to the first substrate (SUB1), selects the metal wiring (MLINE) line-sequentially, and inputs a voltage from the power supply. The second peripheral circuit (SC2) is connected to the second substrate (SUB2), detects the voltage (DSIG) by selecting the metal wiring (MLINE) line-sequentially.

FIG. 14 is a cross-sectional view of the display device with a touch panel shown in FIG. This is a cross-sectional view showing the state where the touch panel of FIG. 13 is attached to the surface of the display panel in more detail.
The display device with a touch panel shown in FIG. 14 includes a display panel substrate (PSUB), a first substrate (SUB1), a second substrate (SUB2), a spacer (SPACER), and a circularly polarizing plate (CPOL). It has. The display panel substrate (PSUB) is made of alkali-free glass and is a substrate on the display surface side, such as a counter substrate of a liquid crystal display device and a sealing substrate of a top emission type organic EL display device.
The first substrate (SUB1) is bonded onto the display panel substrate (PSUB). The second substrate (SUB2) is fixed to the first substrate (SUB1) with a sealing agent (not shown) via a spacer (SPACER). The circularly polarizing plate (CPOL) is fixed on the second substrate (SUB2).
FIG. 15 is an enlarged cross-sectional view of the first substrate (SUB1) in the AA region of FIG.
As described above, the metal wiring (MLINE) is disposed on the resin film (RESIN) made of PET.
In the touch panel shown in FIG. 13, the wiring pitch (PITCH) of the metal wiring (MLINE) is 80 to 1000 μm, the wiring width (WIDTH) is 8 to 50 μm, the wiring height (HEIGHT) is 10 to 150 μm, and the spacer (SPACER) height 5 ˜50 μm, and the resin film (RESIN) thickness can be appropriately produced from 35 to 300 μm.

In FIG. 13, a touch panel having a pair of substrates (SUB1, SUB2) having electrodes on opposite surfaces, a spacer (SPACER) that holds a gap between the pair of substrates, and a display panel disposed on the back surface of the touch panel, In the display device with a touch panel including the above, at least one substrate uses a metal wiring (MLINE) formed on a resin film (RESIN).
Accordingly, in the touch panel shown in FIG. 13, a basic recognition structure can be realized by attaching a resin film (RESIN) provided with a metal wiring (MLINE) through a spacer (SPACER). A touch panel that can be input and has high durability can be manufactured at low cost.
Also, bright display cannot be realized unless the width of the metal wiring (MLINE) is made smaller than 50% of the wiring pitch of the metal wiring (MLINE). Further, since the polarizing plate (CPOL) is provided outside the second substrate (SUB2), reflection of external light can be suppressed.
Further, by providing the spacer (SPACER) between the pair of substrates, the gap between the pair of substrates can be held uniformly, and the maximum width of the planar shape viewed from the substrate direction of the spacer (SPACER) Since the pitch is larger than the pitch of the wiring (MLINE), a short circuit between the opposing metal wirings (MLINE) due to deformation of the resin film (RESIN) can be prevented, and erroneous recognition of the touch panel can be suppressed. In addition, the possibility of a short circuit between the metal wirings (MLINE) can be reduced.

Further, unlike the transparent conductive film (TLINE) such as ITO, the metal wiring (MLINE) does not transmit light, so the width of the metal wiring (MLINE) must be less than 50% of the wiring pitch of the metal wiring (MLINE). , The transmittance decreases. Further, when the wiring width is 13 to 20 μm, an inexpensive milk photomask can be used.
This metal wiring (MLINE) is an opaque metal film, and in addition to aluminum (Al), non-ferrous metals such as carbon (C), copper (Cu), stainless steel (SUS), and iron (Fe) and iron can be used. . Note that the surface of the metal wiring (MLINE) may be blackened. In addition to PET, TAC (triacetyl cellulose) can also be applied as the resin film of the first substrate (SUB1) and the second substrate (SUB2). As described above, other materials can be used as long as the film has little birefringence.
In the touch panel shown in FIG. 13, a fine wiring pattern by metal wiring (MLINE) can sufficiently achieve a definition of 300 lpi (line per inch), and in the conventional example, it is about 10 ppi (point per inch). The resolution can be improved 10 times or more. In addition, since the fine wiring pattern can be sufficiently manufactured with a width of about 10 μm and a thickness of about 10 μm, the transmittance can be improved as compared with the current resistive film type touch panel by designing the resolution to about 100 lpi. It becomes possible.
Although there is a cost problem, the metal wiring (MLINE) can be manufactured not only by etching but also by deposition or plating.

[Example]
FIG. 1 is a diagram for explaining resolution on a touch panel in a display device with a touch panel according to an embodiment of the present invention.
The display device with a touch panel of the embodiment of the present invention has the same configuration as that of the touch panel shown in FIG. 13, but in this embodiment, the touch panel has a plurality of areas having different detection resolutions (the high resolution detection area HAR of FIG. 1). , And is divided into low-resolution detection areas LAR). Here, as an assumed usage method, the low resolution detection region LHR is mainly used for a push button, a confirmation dialog box, or the like.
Corresponds to this application.
FIG. 2 is a diagram for explaining a display device with a touch panel according to an embodiment of the present invention.
The X-coordinate detection film (XSUB) and Y-coordinate detection film (YSUB) of the touch panel of this example are similar to the touch panel shown in FIG. 13 on the metal wiring (resin) made of PET (resin). MLINE).
In the touch panel of this embodiment, the X coordinate detection film (XSUB) is fixed to the Y coordinate detection film (YSUB) with a sealant (not shown) through a spacer (not shown). Further, a circularly polarizing plate (CPOL) may be disposed on the X coordinate detection film (XSUB).

Also in this embodiment, the wiring pitch (PITCH) of the metal wiring (MLINE) is 80 to 1000 μm, the wiring width (WIDTH) is 8 to 50 μm, the wiring height (HEIGHT) is 10 to 150 μm, and the height of the spacer (SPACER) is 5 to 50 μm. The thickness of the resin film (RESIN) can be appropriately manufactured up to 35 to 300 μm.
This metal wiring (MLINE) is an opaque metal film, and in addition to aluminum (Al), non-ferrous metals such as carbon (C), copper (Cu), stainless steel (SUS), and iron (Fe) and iron can be used. . Note that the surface of the metal wiring (MLINE) may be blackened. In addition to PET, TAC (triacetyl cellulose) can also be applied as the resin film of the first substrate (SUB1) and the second substrate (SUB2). As described above, other materials can be used as long as the film has little birefringence.
Even in the touch panel of this embodiment, a fine wiring pattern by metal wiring (MLINE) can sufficiently achieve a definition of 300 lpi (line per inch). In addition, since the fine wiring pattern can be sufficiently manufactured with a width of about 10 μm and a thickness of about 10 μm, the transmittance can be improved as compared with the current resistive film type touch panel by designing the resolution to about 100 lpi. It becomes possible. Although there is a cost problem, the metal wiring (MLINE) can be manufactured not only by etching but also by deposition or plating.

The first method for setting a plurality of regions having different detection resolutions on the touch panel, such as the high-resolution detection region HAR and the low-resolution detection region LAR in FIG. 1, is a method of switching flexibly by software. is there.
The switching by this software can be realized by, for example, converting the coordinates of the detection points detected in the low resolution detection area LAR in FIG. 1 into low resolution coordinates using a table or the like. The advantage of this first method is that the detection resolution region can be freely defined by the application to be used.

A second method for setting a plurality of areas having different detection resolutions on the touch panel, such as the high resolution detection area HAR and the low resolution detection area LAR in FIG. 1, is the high resolution detection area HAR in FIG. The metal wiring (MLINE) is divided at the boundary with the low resolution detection area LAR, and the number of metal wirings (MLINE) in the low resolution detection area LAR is reduced as compared with the high resolution detection area HAR (in other words, , The wiring pitch of metal wiring (MLINE) is increased).
The configuration in this case is shown in FIGS. 3A and 4A show the configuration of the X coordinate detection film (XSUB), and FIGS. 3B and 4B show the configuration of the Y coordinate detection film (YSUB). . 3 and 4, the FPC connects each metal wiring (MLINE) of the touch panel to the peripheral circuits (the first peripheral circuit (SC1) and the second peripheral circuit (SC2) shown in FIG. 13). This is a flexible wiring board.
In the configuration shown in FIG. 3, the X-coordinate detection film (XSUB) is divided into two areas XA and XB, and the Y-coordinate detection film (YSUB) is divided into two areas YA and YB. In addition, the number of metal wires (MLINE) in the region XA is increased, the number of metal wires (MLINE) in the region XB is less than the number of metal wires (MLINE) in the region XA, and similarly, The number of metal wires (MLINE) is large, and the number of metal wires (MLINE) in the region YB is smaller than the number of metal wires (MLINE) in the region YA.
In the configuration shown in FIG. 3, the region where the region XA and the region YA overlap is the high-resolution detection region HAR, the region where the region XA and the region YB overlap, the region where the region XB and the region YA overlap, and the region XB A region where the region YB and the region YB overlap is a low resolution detection region LAR.
In this case, in the region where the region XA and the region YB overlap and the region where the region XB and the region YA overlap, one of the metal wirings (MLINE) has a larger number of wirings than the other metal wiring (MLINE). Low resolution can be achieved by software control.

In the configuration shown in FIG. 4, the X-coordinate detection film (XSUB) is divided into two L-shaped shapes so that the region where the region XA and the region YB overlap and the region where the region XB and the region YA overlap are eliminated. It is divided into regions XA and XB, and the Y coordinate detection film (YSUB) is divided into two regions YA and YB in an L-shape.
In FIG. 3 and FIG. 4, since the area is divided in each of the X coordinate detection film (XSUB) and the Y coordinate detection film (YSUB), a flexible cable is generally required at both ends. Of course, a flexible cable may be installed on one side or adjacent side by routing the wiring.
In addition, since one pitch is sufficient for dividing the area, if the pitch is 0.5 mm or less, it cannot be visually observed and can be functionally the same as a continuous wiring touch panel.
Furthermore, since the wiring resolutions of the areas XA and XB and the areas YA and YB can be freely designed, the burden on the software can be reduced when the operation of the touch panel is performed in a prescribed pattern.
Note that the number of wirings (wiring pitch) of the metal wirings (MLINE) in the regions XA and XB and in the regions YA and YB is made equal, and the high-resolution detection region HAR and the low-resolution detection are performed by software control as in the method 1 described above. You may make it divide | segment into area | region LAR.

A third method for setting a plurality of regions having different detection resolutions on the touch panel, such as the high resolution detection region HAR and the low resolution detection region LAR in FIG. 1, is the high resolution detection region HAR in FIG. The metal wiring (MLINE) is divided at the boundary with the low-resolution detection area LAR, and a plurality of (here, two) metal wirings (MLINE) are connected to one terminal in the low-resolution detection area LAR. is there.
The configuration in this case is shown in FIGS. 5 (a) and 6 (a) show the configuration of the X coordinate detection film (XSUB), and FIGS. 5 (b) and 6 (b) show the configuration of the Y coordinate detection film (YSUB). . 5 and 6, the FPC connects each metal wiring (MLINE) of the touch panel to the peripheral circuits (the first peripheral circuit (SC1) and the second peripheral circuit (SC2) shown in FIG. 13). It is a flexible wiring board.
In the configuration shown in FIG. 5, the X coordinate detection film (XSUB) is divided into two areas XA and XB, and the Y coordinate detection film (YSUB) is divided into two areas YA and YB. Similarly, the number of metal wirings (MLINE) in the regions XA and XB is the same, and the number of metal wirings (MLINE) in the regions YA and YB is also the same, and the metal wiring (MLINE) in the region XB is set every two. Bundling, connecting to the same wiring (FLINE) of the flexible wiring board (FPC), bundling every two metal wirings (MLINE) in the region YB, and connecting to the same wiring (FLINE) of the flexible wiring board (FPC) is there.
The metal wiring (MLINE) of the X coordinate detection film (XSUB) or the Y coordinate detection film (YSUB) and the wiring (FLINE) of the flexible wiring board (FPC) are made of an anisotropic conductive film or the like. Connected.

In the configuration shown in FIG. 5, the region where the region XA and the region YA overlap is the high-resolution detection region HAR, the region where the region XA and the region YB overlap, the region where the region XB and the region YA overlap, and the region XB A region where the region YB and the region YB overlap is a low resolution detection region LAR.
In this case, in the region where the region XA and the region YB overlap and the region where the region XB and the region YA overlap, one of the metal wirings (MLINE) has a wiring pitch wider than that of the other metal wiring (MLINE). Low resolution can be achieved by software control.
In the configuration shown in FIG. 6, the X-coordinate detection film (XSUB) is divided into two L-shaped shapes so that the region where the region XA and the region YB overlap and the region where the region XB and the region YA overlap are eliminated. It is divided into regions XA and XB, and the Y coordinate detection film (YSUB) is divided into two regions YA and YB in an L-shape.
In the configurations shown in FIGS. 5 and 6, the wiring resolutions of the regions XA and XB and the regions YA and YB can be freely designed. Therefore, when the operation of the touch panel is performed in a prescribed pattern, the software burden Can be reduced.

In this embodiment, as shown in FIG. 7, the wiring pitch of the flexible wiring board (FPC) connected to the touch panel (FLINE) is gradually increased from the area connected to the touch panel to the area connected to the peripheral circuit. You may make it narrow. In this case, the connector for connecting the flexible wiring board (FPC) to the peripheral circuit can be reduced in size.
Further, as shown in FIG. 8, the wiring pitch of the metal wiring (MLINE) around the resin film (RESIN) may be gradually reduced. In this case, the width of the flexible printed circuit board (FPC) can be reduced, and the convenience at the time of incorporation in the housing is improved. Therefore, the housing in which the touch panel of the present invention is incorporated can be downsized. Alternatively, when the size of the touch panel is increased, the flexible wiring board (FPC) can be reduced, and the degree of freedom for mounting the touch panel can be improved.
Further, as shown in FIG. 9, the resin film (RESIN) may be extended to an external terminal while narrowing the wiring pitch outside the detection area of the touch panel. That is, the external terminal and the wiring to the external terminal (MLINEF) are formed on the resin film (RESIN) on which the metal wiring (MLINE) is formed, not on a separate substrate (flexible wiring substrate).
In the structure shown in FIG. 9, since a striped metal wiring (MLINE) and a wiring for connecting to a peripheral circuit can be formed simultaneously, the number of parts can be reduced, connection reliability can be improved, and cost can be reduced. It becomes.

Here, the flexible printed circuit board (FPC) is connected to peripheral circuits (first peripheral circuit (SC1) and second peripheral circuit (SC2) shown in FIG. 13) by a connector (CONT) as shown in FIG. The
As shown in FIG. 11, the flexible wiring board (FPC) may be directly connected to a display panel (for example, a liquid crystal display panel or an organic EL display panel) (PANEL). In this case, a shift clock (for example, a scanning clock) for the display panel is input to one film (X coordinate detection film (XSUB) or Y coordinate detection film (YSUB)) of the touch panel (TAP). Thus, the shift clock for the display panel may be detected as a signal for detecting the position of the touch panel.
As mentioned above, the invention made by the present inventor has been specifically described based on the above embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. Of course.
