Description

  The present invention relates to a flexible wiring board and an information processing apparatus, and more particularly to a flexible wiring board used in a touch panel display device including an image display panel such as a liquid crystal panel or an organic electroluminescence panel and a touch panel, and such a flexible wiring board. The present invention relates to an information processing apparatus provided with a touch panel display device.

  Conventionally, display devices of many portable information devices such as mobile phones, personal digital assistants (PDAs), digital cameras, and multimedia players include liquid crystal modules (liquid crystal display devices) and organic electroluminescence modules (organic EL displays). For example, a thin image display device is used.

  Recently, an image display device provided with a touch panel has been provided in order to improve the operability of information equipment (Patent Document 1).

  FIG. 18 is a perspective view showing a touch panel constituting the image display device disclosed in Patent Document 1. As shown in FIG.

  The touch panel TP includes a touch panel substrate TPS that is a transparent substrate, and an electrode TPE of the touch panel is formed on one side of the touch panel substrate TPS. A flexible printed circuit FPC is used for the wiring connected to the touch panel TP. This flexible printed circuit is also called a flexible printed circuit board or a flexible wiring board, and is hereinafter referred to as a flexible printed circuit board.

  Here, a driving IC chip TPIC for driving the touch panel TP is mounted on a part of the flexible printed board FPC, one end of the flexible printed board FPC is connected to the touch panel board TPS, and the other end of the flexible printed board FPC is It is an interface unit IFT.

  FIG. 19 is a cross-sectional view showing an example of a liquid crystal display device having such a touch panel.

  The liquid crystal display device 50 includes a touch panel TP and a liquid crystal panel LCP, and the touch panel TP and the liquid crystal panel LCP are arranged so as to overlap each other so that the touch panel TP is located on the front surface side. Further, the liquid crystal panel LCP and the touch panel TP are disposed so as to be in close contact with a transparent resin layer (not shown) interposed therebetween.

  In the liquid crystal display device 50, a front panel FW that protects the liquid crystal panel LCP and the touch panel TP is provided above the touch panel TP.

  Here, the flexible printed circuit board FPCt is bonded to the touch panel substrate TPS constituting the touch panel TP by FOG pressure bonding (that is, heat pressure bonding using an anisotropic conductive film), and a part of the flexible printed circuit board FPCt. Is mounted with a driving IC chip TPIC for driving the touch panel TP. In FIG. 18, FOG is a joint between the touch panel substrate TPS and the flexible printed circuit board FPCt.

  The liquid crystal panel LCP includes a TFT substrate TFTS on which circuit elements such as thin film transistors are formed, and a color filter substrate (counter substrate) CFS on which color filters are formed. The TFT substrate TFTS and the color filter substrate ( The counter substrate is disposed so as to face the CFS. A region between the TFT substrate TFTS and the color filter substrate CFS is sealed with a sealing material SH, and a region between these substrates is filled with liquid crystal LC. A backlight unit BLU is provided on the rear surface side of the TFT substrate TFTS via a lower polarizing plate SPP, and an upper polarizing plate UPP is provided on the upper surface side of the color filter substrate CFS. Further, a driver chip DRC for driving a liquid crystal panel is provided on a portion of the TFT substrate TFTS located outside the color filter substrate CFS, and another flexible printed circuit board FPCd is connected to one end of the TFT substrate TFTS by a joint FOG. Is connected.

  As described above, in the liquid crystal display device 50 including the touch panel TP, the touch panel TP and the liquid crystal panel LCP are arranged close to each other, so that many wires exist in a narrow space, and the liquid crystal display device is thinned. Is getting harder.

  In addition, in an organic EL display device using a touch panel, it is necessary to secure an arrangement space for wiring, so that it is difficult to reduce the thickness as in a liquid crystal display device.

  Patent Document 1 discloses that in a liquid crystal display device, a liquid crystal panel LCP and a touch panel TP that are arranged close to each other as described above are connected by wiring to reduce the number of components and the connection process. In addition, since the distance between the liquid crystal panel LCP and the touch panel TP is short, it is difficult to accurately bond the flexible printed circuit board to the liquid crystal panel LCP and the touch panel TP. In addition, after joining the flexible printed circuit board to one panel by FOG pressure bonding, when bonding the flexible printed circuit board to the other panel, measures against the problem that the previously bonded part is removed due to the heat effect of FOG pressure bonding What has been taken is disclosed.

  FIG. 20 is a cross-sectional view for explaining such a liquid crystal display device, in which the same reference numerals as those in FIG. 19 denote the same components.

  Similarly to the liquid crystal display device 50 shown in FIG. 19, the liquid crystal display device 50a includes a liquid crystal panel LCP and a touch panel TP disposed on the front surface (upper side of the paper surface) of the liquid crystal panel LCP. In the liquid crystal display device 50a, the liquid crystal panel LCP and the touch panel TP are connected by a single flexible printed circuit board FPC0.

  Specifically, the above-described anisotropic conductive film is used to join the flexible printed circuit board FPC0 to the TFT substrate TFTS of the liquid crystal panel LCP and the transparent touch panel substrate TPS of the touch panel TP. This anisotropic conductive film is a mixture of thermosetting resin and metal particles whose surfaces are covered with an insulating layer. The anisotropic conductive film is sandwiched between the electrode portion of the flexible printed circuit board and the electrode of the electronic component (liquid crystal panel or touch panel) and pressed while heating, so that the anisotropic conductive film of the flexible printed circuit board or electronic Pressure is applied only to the part where the electrode of the component contacts, and a conductive path is formed between the electrode of the flexible printed circuit board and the electrode of the electronic component, and insulation is performed on the part of the anisotropic conductive film where pressure is not applied. Sex is preserved.

  Further, in this liquid crystal display device 50a, the anisotropic conductive film for bonding the flexible printed circuit board FPC0 to the TFT substrate TFTS of the liquid crystal panel LCP is anisotropic for bonding the flexible printed circuit board FPC0 to the substrate TPS of the touch panel. In the process of connecting the liquid crystal panel LCP and the touch panel TP with one flexible printed circuit board FPC0 using a resin having a higher glass transition temperature than that of the conductive conductive film, One end of the flexible printed circuit board FPC0 is connected to the TFT substrate TFTS of the liquid crystal panel LCP by FOG pressure bonding, and then the other end of the flexible printed circuit board FPC0 is connected to the transparent substrate TPS of the touch panel TP by FOG pressure bonding.

  As described above, an anisotropic conductive film having a high glass transition temperature is used for the bonding between the flexible printed circuit board FPC0 and the liquid crystal panel LCP, and the glass film is used for bonding between the flexible printed circuit board FPC0 and the touch panel PT performed later. Since an anisotropic conductive film having a low transition temperature is used, the flexible printed circuit board FPC0 and the liquid crystal panel LCP connected earlier are affected by the heat of the FOG pressure bonding when the flexible printed circuit board FPC0 and the touch panel TP are joined later. Bonding is difficult to come off. That is, when the touch panel TP and the TFT substrate TFTS are connected by the flexible printed board, it is possible to suppress the disconnection between the previously connected flexible printed board FPC0 and the liquid crystal panel LCP.

  Also, in the state where the flexible printed circuit board is connected to the liquid crystal panel having a narrow pitch between the connection wirings, the touch panel is not connected to the flexible printed circuit board, so that the two can be joined with high accuracy without being disturbed by the touch panel. Yes, when connecting a flexible printed circuit board to the touch panel, the liquid crystal panel connected to the flexible printed circuit board interferes with the bonding work, but the pitch interval of the connection wiring of the touch panel is wider than the liquid crystal panel, so some deviation occurs Even so, there is no connection failure.

  In FIG. 20, FOG1 indicates a joint formed by FOG pressure bonding between one end of the flexible printed circuit board FPC0 and the TFT substrate TFTS, and FOG2 indicates the other end of the flexible printed circuit board FPC0 and the transparent substrate TPS of the touch panel TP. 2 shows a joint formed by FOG pressure bonding.

  Hereinafter, the operation on the touch panel will be described in detail.

  In the touch control circuit (touch panel control IC) 506 of the touch panel, when the drive line drive unit 110 controlled by the control unit 130 applies the drive signal Dr to the signal lead lines T1a to T1f, T3a, and T3b of the touch panel body 504, this drive is performed. The first electrode lines 11a to 11f and the third electrode lines 13a and 13b are driven by the signal Dr, and thereby the sense voltage generated on the second electrode lines 12a to 12f and the fourth electrode lines 14a and 14b is sensed. The signal Se is output from the signal lead lines T2a to T2d, T4a, and T4b to the sense line detection unit 120.

  In the sense line detection unit 120, the amplifier circuit 121 amplifies the input sense signal Se and outputs the amplified sense signal Se to the signal selection unit 122. The signal selection unit 122 selects sense signals from the amplifier circuit 121 and sequentially outputs them to the A / D conversion unit 123. The A / D converter 123 digitizes the sense signal and outputs it to the end detector 126a. The end detection unit 126a detects sense signals from the fourth electrode lines 14a and 14b located at both ends of the touch region 101, and the detected digital sense signal is a fourth signal located at the end of the touch region 101. The information indicating that it is from the electrode lines 14a and 14b is added to the touch line correction processing unit 126b. The touch level correction processing unit 126b outputs the digital sense signal obtained from the fourth electrode lines 14a and 14b located at the end of the touch area 101 of the panel unit 504 to the second electrode lines 12a to 12d other than the end. Is corrected so as to have the same signal level as that of the digital sense signal obtained from the above. In the touch level correction processing unit 126b, the digital sense signals obtained from the second electrode lines 12a to 12d located outside the touch region end are output to the decoding processing unit 124 without being corrected.

  The decoding processing unit 124 detects a capacitance value between adjacent electrodes on the touch panel by decoding the digitized sense signal, and outputs the detected capacitance value to the touch position calculation unit 125. The touch position calculation unit 125 creates and outputs touch position information Dt indicating the touch position in the touch area based on the detected capacitance value between adjacent electrodes. Touch position information Dt output from the touch panel display device 500 is supplied to the system control unit 521 via the data bus 503.

  Further, the control unit 130 controls operation timings in the drive line control unit 110, the amplifier circuit 121, and the signal selection unit 122 based on the touch position information Dt.

  In addition, the system control unit 521 determines the operation content of the operator, and outputs display data to the display control unit 507 so that an image corresponding to the operation content is displayed on the display unit 505.

  Here, in a state where the touch operation is not performed on the touch panel 550, the capacitance value between the adjacent electrodes is uniform over the entire surface of the touch region. That is, the capacitance value between adjacent electrodes distributed in a matrix in the touch area is constant.

  In such a state, when a finger or the like that is a conductor touches any part of the touch panel body, there is a capacitance between the electrode line and the finger, and the electrode of the electrode line to which the drive signal is applied at the touch position And the capacitance value between the electrode of the electrode line from which the sense signal is extracted decreases. The touch panel control circuit 560 detects the position touched by the finger by taking out the decrease in the touch panel body 504 as a sense signal.

  Next, the manufacturing method of a flexible printed circuit board is demonstrated.

  First, in the first conductive layer forming step, an intersection portion where wiring in the touch panel conductor layer 514 intersects on the insulating transparent base material (polyimide film) 3 constituting the touch panel flexible substrate (flexible wiring substrate). The other portions and the lower portions (diamond electrodes) 15 and 16 and the triangular electrodes 17 and 18 at the intersection are formed of a conductive material. At this time, signal lines L1a to L1f and L3a, L3b, L2a to L2d and L4a and L4b, and signal lead lines T1a to T1f and T3a, T3b, T2a to T2d and T4a and T4b are also formed at the same time.

  Next, in the insulating layer forming step, the insulating layer 4a is selectively formed on the transparent substrate 3 in a region including the intersecting portion and the peripheral portion of the intersecting portion.

  Subsequently, in the second conductive layer forming step, a conductive layer 4b made of a conductive material is formed on the transparent substrate 3 in a region including the upper portion of the insulating layer 4a and the peripheral portion of the insulating layer 4a. A portion located on the upper side at the intersection of the touch panel conductor layer is formed.

  Thus, after forming the portion other than the intersection where the wirings in the touch panel conductor layer intersect, and the lower portion of the intersection with the conductive material, the intersection and the peripheral portion of the intersection are formed. An insulating layer is selectively formed in a region including the conductive layer, and then a conductive layer made of a conductive material is formed in a region including an upper portion of the insulating layer and a peripheral portion of the insulating layer, and the intersection portion of the conductor layer for the touch panel is formed. By forming the upper part, the conductive layer for the touch panel including the part where the wiring intersects three-dimensionally can be efficiently formed without forming an interlayer insulating film or forming a contact hole. be able to.

  Here, an ITO film is formed as a conductor layer in the first conductive layer forming step and the second conductive layer forming step. In the case where the plurality of electrodes forming the touch region are made of an ITO film, a small and medium touch panel can be provided at a low price.

  However, the first conductive layer forming step and the second conductive layer forming step include a metal fine wire step for forming a metal fine wire, and a plurality of electrodes constituting the electrode portion by the metal fine wire step, that is, rhombus electrodes and triangular electrodes , Signal wirings, and signal lead lines may be formed. In this case, the resistance of the electrode or the like is lowered, thereby increasing the response speed of the touch panel, and a large touch panel can be realized at high speed. That is, it is possible to provide an efficient manufacturing method of a flexible wiring board necessary for a large touch panel display device and an information processing apparatus including the large touch panel display device.

The joint portion between the wiring and the signal lead line becomes unnecessary, and the problem of poor connection between them is solved, and the frame portion 100b where touch input located at the periphery of the electrode portion 514a (that is, the touch area 100) of the touch panel 550 cannot be performed. Can be narrowed. Moreover, since it is not necessary to bond the flexible substrate FPC for touch panels with different types of anisotropic conductive films as in Patent Document 1, it is possible to reduce the trouble of arranging different materials as the anisotropic conductive film that is a material for manufacturing. .

  Further, since the touch panel mounting pattern region 533 for mounting an IC as a touch panel controller is provided on the touch panel flexible substrate FPC, an analog signal corresponding to a signal applied to the electrode portion 514a of the touch panel body 504 or a signal acquired from the electrode portion 514a. The wiring between the touch panel control circuit (touch panel control IC) 506 that performs processing and the electrode portion 514a is shortened, and noise can be suppressed.

  In addition, a shape including a symmetry axis portion obtained by dividing the shape of the electrode located in the peripheral portion of the electrode portion 514a of the touch panel by the symmetry axis along the extending direction of the electrode line from the shape of the electrode located in a region other than the peripheral portion. Therefore, a sense signal can be acquired from the electrode line arranged at the very periphery of the electrode part, and a touch panel in which the influence of noise at the periphery of the electrode part is suppressed can be provided. That is, electrodes that are electrically connected in the vertical direction or the horizontal direction up to the edge of the peripheral portion of the touch area are arranged, and thereby, a sense signal having a high S / N ratio can be obtained from the electrode located in the peripheral portion of the electrode portion. It can acquire and the influence of the noise in the peripheral part of an electrode part can be suppressed.

  In Embodiment 1, after forming a portion other than the intersecting portion where the wirings in the conductor layer for the touch panel intersect with each other and a portion positioned below the intersecting portion with a conductive material, the intersecting portion and the intersecting portion are formed. An insulating layer is selectively formed in a region including the peripheral portion of the conductive layer, and then a conductive layer made of a conductive material is formed on the insulating layer and in the region including the peripheral portion of the insulating layer. Since the upper portion is formed at the intersection, the touch panel conductor layer including the portion where the wiring intersects three-dimensionally is formed without forming an interlayer insulating film or forming a contact hole. Can be well formed.
