Description

  The present invention relates to a display device having a display member, a shutter liquid crystal cell and a touch panel provided in front of the display member.

  Patent Document 1 discloses an image display device including an image display panel and a touch panel arranged in front of the display surface of the image display panel. The touch panel described in Patent Document 1 includes a sensor electrode and an opaque extraction circuit that is electrically connected to the sensor electrode in a non-display area. The take-out portion having the take-out circuit is bent so as to face the side surface with respect to the display surface of the image display panel. Thereby, narrowing of the frame is achieved.

JP 2014-157400 A

  However, in the image display device disclosed in Patent Document 1, while the frame is narrowed, the display area is not operating (when the device displaying various information in the display area is not turned on) When the display area is viewed from the front side, the color of the display area is not the same as the color of the non-display area (frame area).

  For example, there is a demand for the display area to have the same color as the non-display area when not in operation, and the display contents gradually emerge in the display area when the operation starts (fade in). Alternatively, there is a demand that the display content gradually disappears from the display area when the operation ends, and that the color of the display area becomes the same as the color of the non-display area when not operating (fade out). That is, there is a desire to make the display area color the same as the non-display area color so that the boundary between the display area and the non-display area cannot be seen during non-operation.

  Therefore, a display device in which a liquid crystal shutter is disposed so as to overlap an image display panel has been studied. According to this display device, the color of the display area can be made the same as the color of the non-display area when not operating.

  However, when a touch panel is provided in a display device provided with a liquid crystal shutter, a new problem arises. That is, when the touch panel is arranged at a position relatively close to the surface of the display device, there is a problem that the wiring provided outside the transmissive region (the region included in the detection region) of the touch panel can be seen from the surface side of the display device. Alternatively, when the touch panel is disposed at a position relatively far from the surface of the display device, there is a problem that the detection sensitivity of the touch panel is lowered while the wiring can be made invisible from the surface side of the display device.

  The present invention is for solving the above-described conventional problems, and in a display device provided with a liquid crystal shutter, the display of the touch panel can be made invisible and the detection sensitivity of the touch panel can be maintained. An object is to provide an apparatus.

The present invention provides a display member having a display region and a non-display region provided around the display region, a first region disposed in front of the display member and corresponding to the display region, and the non-display region In a display device provided with a shutter liquid crystal cell that forms a second region corresponding to
A first polarizing plate overlaid in front of the shutter liquid crystal cell, a second polarizing plate overlaid behind the shutter liquid crystal cell, and a touch panel disposed in front of the shutter liquid crystal cell,
The shutter liquid crystal cell switches the first region between a transmissive state and a non-transmissive state, and the second region is set to a non-transmissive state.
The touch panel has a transmissive region and a wiring region extending from the transmissive region, a transparent electrode is formed in the transmissive region, and an opaque wiring that is electrically connected to the transparent electrode is formed in the wiring region.
The touch panel is bent, and the wiring area is arranged behind the shutter liquid crystal cell.

  According to the display device of the present invention, the liquid crystal shutter is disposed so as to overlap the display member, and the first region of the liquid crystal shutter is switched between the transmission state and the non-transmission state corresponding to the display region of the display device. On the other hand, the second area of the liquid crystal shutter is set in an opaque state corresponding to the non-display area of the display device. Therefore, the color of the display area when the first area is set to the opaque state can be made the same as the color of the non-display area.

  In the present invention, it is preferable that the transmissive region of the touch panel is sandwiched between the shutter liquid crystal cell and the first polarizing plate.

  When the operation of the shutter liquid crystal cell is stopped, the first region and the second region are in the non-transmissive state with the same color from the front of the first polarizing plate. Therefore, when the first area is switched to the non-transmissive state, the presence of the touch panel is not visible from the front.

  In the display device of the present invention, the wiring area of the touch panel is located between the second polarizing plate and the non-display area of the display member.

  A wiring area where wiring is provided in the touch panel corresponds to the second area of the liquid crystal shutter, and is provided on the display member side as viewed from the second polarizing plate. That is, the wiring area of the touch panel is provided on the back side of the second polarizing plate when viewed from the surface side of the display device. Therefore, the wiring area of the touch panel can be made invisible from the surface side of the display device.

  Alternatively, in the display device of the present invention, the wiring area of the touch panel is located behind the display member.

  In the present invention, the transmissive region of the touch panel corresponds to the first region of the liquid crystal shutter, and is between the liquid crystal cell and the first polarizing plate provided on the side opposite to the display member as viewed from the liquid crystal cell. Is provided.

Therefore, the transmissive region of the touch panel is arranged at a relatively close position on the surface of the display device. Thereby, the detection sensitivity of a touchscreen can be maintained and an operation position can be detected reliably.

  Furthermore, in the display device of the present invention, the touch panel has a peripheral region between the transmissive region and the wiring region, and the peripheral region faces a side of the shutter liquid crystal cell. It is possible that non-transparent wiring exists in at least a part of the peripheral region.

  As described above, even if non-transparent wiring is arranged in the peripheral area, the peripheral area is located behind the second area, so that the shutter liquid crystal cell wiring is not seen from the front.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the display apparatus which can maintain the detection sensitivity of a touch panel while being able to hide the wiring of a touch panel in the display apparatus provided with the liquid-crystal shutter.

FIG. 2 is a schematic perspective view showing an arrangement relationship between the shutter portion and the display member.

  The display device 10 according to the present embodiment includes a shutter unit 100 and a display member 200. The shutter unit 100 is disposed in front of the display member 200. The display member 200 is, for example, a liquid crystal display device or an electroluminescence device. In the description of the present embodiment, a case where the display member 200 is a liquid crystal display device is taken as an example.

The second region 100B corresponds to the non-display region 200B and has an area larger than the area of the non-display region 200B. As a result, the non-display area 200 </ b> B of the display member 200 is shielded from the user of the display device 10. That is, it becomes impossible for the user of the display device 10 to see the non-display area 200B from the surface side of the display device 10 (upper side in FIG. 1).

  The first area 100A is set in a transmissive state when the display area 200A is operating (when the display member 200 is operating). On the other hand, the first area 100A is set in an opaque state when the display area 200A is not operating (when the display member 200 is not operating). The second area 100B is set in an opaque state both when the display area 200A is in operation and when it is not in operation. These settings are performed when the shutter unit 100 receives a control signal transmitted from the control unit 310.

  The first polarizing plate 120 shown in FIG. 3 is provided on the side opposite to the display member 200 when viewed from the shutter liquid crystal cell 110. The second polarizing plate 130 is provided between the shutter liquid crystal cell 110 and the display member 200. The angle of the transmission axis of the first polarizing plate 120 is the same as the angle of the transmission axis of the second polarizing plate 130.

  As illustrated in FIGS. 3, 5, and 6, the touch panel 140 includes a transmissive region 140 </ b> A, a peripheral region 140 </ b> B, and a wiring region 140 </ b> C. The transmissive area 140 </ b> A corresponds to the first area 100 </ b> A of the shutter unit 100 in FIG. 2, and corresponds to the display area 200 </ b> A of the display member 200. That is, the transmissive area 140 </ b> A corresponds to the first area 100 </ b> A of the shutter unit 100. As illustrated in FIG. 3, the transmission region 140 </ b> A is provided between the shutter liquid crystal cell 110 and the first polarizing plate 120.

  The peripheral area 140B and the wiring area 140C of the touch panel 140 are provided outside the transmissive area 140A. The peripheral region 140B is provided between the transmissive region 140A and the wiring region 140C. The peripheral area 140B and the wiring area 140C correspond to the second area 100B of the shutter unit 100 and correspond to the non-display area 200B of the display member 200. That is, the peripheral region 140B and the wiring region 140C correspond to the second region 100B of the shutter unit 100.

  As shown in FIG. 3, the peripheral region 140B passes through the side surface of the shutter liquid crystal cell 110 and extends to the wiring region 140C. The wiring region 140C is provided on the display member 200 side as viewed from the second polarizing plate 130. Specifically, the wiring region 140 </ b> C is provided between the second polarizing plate 130 and the display member 200.

As illustrated in FIG. 6, the touch panel 140 includes a base material 141, a first transparent electrode 142, and a second transparent electrode 143. The first transparent electrode 142 and the second transparent electrode 143 correspond to the transparent electrode of the present invention. For example, the base material 141 has translucency and is formed of a film-like transparent base material such as polyethylene terephthalate (PET). The first transparent electrode 142 and the second transparent electrode 143 are provided in the transmission region 140A and the peripheral region 140B on the surface of the base material. For example, the first transparent electrode 142 and the second transparent electrode 143 are formed of a transparent conductive material such as ITO (Indium Tin Oxide), SnO ₂ , or ZnO by sputtering or vapor deposition.

As the transparent conductive material, in addition to ITO, SnO ₂ , and ZnO, metal nanowires typified by silver nanowires, thin metals formed in a mesh shape, conductive polymers, and the like can be given. The first transparent electrode 142 and the second transparent electrode 143 may be formed by screen printing with a conductive ink. Alternatively, the first transparent electrode 142 and the second transparent electrode 143 may be formed of a photosensitive conductive sheet (a so-called sheet having a conductive layer in a dry film resist).

  When the transparent conductive material is formed of a metal nanowire typified by silver nanowire, a thin metal formed in a mesh shape, or a conductive polymer, the touch panel 140 can be easily bent in a region where the transparent conductive material is formed.

  The first transparent electrode 142 and the second transparent electrode 143 are connected to the wiring 144 provided in the wiring region 140C. The wiring 144 is connected to the circuit board 340 via the flexible printed board 350. A driving voltage for the first transparent electrode 142 and the second transparent electrode 143 is supplied through the wiring 144. The wiring 144 may be formed of the same transparent conductive material as that of the first transparent electrode 142 and the second transparent electrode 143 by sputtering, vapor deposition, or the like. It may be formed. At least the terminal portion of the wiring 144 is non-transparent.

  The touch panel 140 is, for example, a self-capacitance detection type capacitive sensor. In this case, when the finger is brought into contact with the operation surface (for example, the surface of the surface treatment layer 150), the second transparent electrode between the finger and the first transparent electrode 142 close to the finger and between the finger and the finger is transparent. A capacitance is generated between the electrode 143 and the electrode 143. The touch panel 140 can calculate the contact position of the finger based on the capacitance change at this time. The touch panel 140 detects the Y coordinate of the finger position based on the capacitance change between the finger and the first transparent electrode 142, and changes the capacitance between the finger and the second transparent electrode 143. Based on this, the X coordinate of the finger position is detected.

  Alternatively, the touch panel 140 may be, for example, a mutual capacitance detection type. In this case, the touch panel 140 applies a driving voltage to one row of either the first transparent electrode 142 or the second transparent electrode 143, and the first transparent electrode 142 and the second transparent electrode 143 are applied. A change in capacitance between the other electrode and the finger may be detected. Thereby, the touch panel 140 detects the Y coordinate of the finger position by the other electrode, and detects the X coordinate of the finger position by the one electrode.

  Note that like the touch panel 140 illustrated in FIG. 6, the wiring 144 may be connected to a flexible printed board 350 provided on one side of the touch panel 140. Alternatively, as in the touch panel 140M illustrated in FIG. 7, the wiring 144 may be connected to a flexible printed board 350 provided on a plurality of sides of the touch panel 140. The terminal portion of the wiring 144 is a connector terminal, and the conductive pattern of the flexible circuit board 350 is joined to the connector terminal by soldering or the like. Note that the flexible printed board 350 may be formed by extending a part of the base material 141 constituting the touch panel 140.

  As shown in FIG. 3, the surface treatment layer 150 is provided on the side opposite to the touch panel 140 when viewed from the first polarizing plate 120. The surface treatment layer 150 is provided on the surface of the first polarizing plate 120, and includes an anti-fingerprint (AF) coating layer, an anti-reflection (AR) coating layer, and a hard coating (HC: Hard). -Coat) layer.

  The display member 200 includes a graphic liquid crystal cell 210, a first polarizing plate 220, a second polarizing plate 230, a backlight 240, a surface treatment layer 250, and a case 260. The graphic liquid crystal cell 210, the first polarizing plate 220, the second polarizing plate 230, the backlight 240, and the surface treatment layer 250 are accommodated in a case 260 formed of, for example, metal.

  The graphic liquid crystal cell 210 is, for example, an IPS (In Plane Switchig: registered trademark) liquid crystal cell. The graphic liquid crystal cell 210 is not limited to an IPS (registered trademark) liquid crystal cell. The surface treatment layer 250 includes an anti-glare (AG) coating layer, an anti-reflection (AR) coating layer, and a hard-coat (HC) layer.

  The graphic liquid crystal cell 210 is provided between the first polarizing plate 220 and the second polarizing plate 230. The angle of the transmission axis of the first polarizing plate 220 is orthogonal to the angle of the transmission axis of the second polarizing plate 230. For example, the transmission axis angle of the first polarizing plate 220 is the same as the transmission axis angles of the first polarizing plate 120 and the second polarizing plate 130 of the shutter unit 100. For example, the angle of the transmission axis of the second polarizing plate 230 is orthogonal to the angles of the transmission axes of the first polarizing plate 120 and the second polarizing plate 130 of the shutter unit 100.

  When a voltage having a predetermined frequency and potential difference is applied to the shutter liquid crystal cell 110, the liquid crystal 111 in the shutter liquid crystal cell 110 reacts to enter a transmissive state. As a result, the first region 100A of the shutter unit 100 is in a transmissive state. On the other hand, when the application of the voltage is released, the liquid crystal 111 in the shutter liquid crystal cell 110 returns to the non-reactive state and becomes non-transmissive. As a result, the first region 100A of the shutter unit 100 is in an opaque state.

  Specifically, referring to FIG. 8, the upper transparent electrode 116 includes a first electrode 116A and a second electrode 116C. The first electrode 116 </ b> A corresponds to the first region 100 </ b> A of the shutter unit 100. The second electrode 116 </ b> C corresponds to the second region 100 </ b> B of the shutter unit 100. The lower transparent electrode 117 includes a first electrode 117B and a second electrode 117C. The first electrode 117B corresponds to the first region 100A of the shutter unit 100. The second electrode 117 </ b> C corresponds to the second region 100 </ b> B of the shutter unit 100.

  The controller 310 selectively applies a voltage having the same potential and a voltage having a predetermined frequency and a potential difference from each other to the first electrode 116A and the first electrode 117B. When a voltage having a predetermined frequency and a potential difference from each other is applied to the first electrode 116A and the first electrode 117B, the liquid crystal 111 disposed between the first electrode 116A and the first electrode 117B reacts. And become transparent. On the other hand, when voltages having a predetermined frequency and a potential difference are released and voltages having the same potential are applied to the first electrode 116A and the first electrode 117B, the first electrode 116A and the first electrode 117B are applied. The liquid crystal 111 arranged between and returns to the non-reactive state and becomes non-transparent.

  On the other hand, voltages having the same potential are always applied to the second electrode 116C and the second electrode 117C by the controller 310. Therefore, the liquid crystal 111 disposed between the second electrode 116C and the second electrode 117C does not react and maintains an impermeable state.

  According to the display device 10 according to the present embodiment, the shutter unit 100 is disposed so as to overlap the display member 200, and the first region 100 </ b> A of the shutter unit 100 corresponds to the display region 200 </ b> A of the display member 200. Switch to the transparent state. On the other hand, the second area 100 </ b> B of the shutter unit 100 is set in an opaque state corresponding to the non-display area 200 </ b> B of the display member 200. Therefore, the color of the display area 200A when the first area 100A is set to the opaque state can be the same as the color of the non-display area 200B.

  Here, when a touch panel is provided in a display device provided with a shutter portion, a new problem arises. That is, when the touch panel is disposed at a position relatively close to the surface of the display device, there is a problem that the wiring provided outside the transmission region of the touch panel can be seen from the surface side of the display device. Alternatively, when the touch panel is disposed at a position relatively far from the surface of the display device, there is a problem that the detection sensitivity of the touch panel is lowered while the wiring can be made invisible from the surface side of the display device.

  On the other hand, in the display device 10 according to the present embodiment, the wiring region 140C of the touch panel 140 is provided on the display member 200 side as viewed from the second polarizing plate 130. That is, the wiring region 140 </ b> C is provided on the back side of the second polarizing plate 130 as viewed from the front surface side of the display device 10. Therefore, the wiring region 140 </ b> C can be hidden from the surface side of the display device 10.

  Specifically, the wiring region 140 </ b> C is provided between the second polarizing plate 130 and the display member 200. Accordingly, the wiring region 140 </ b> C is provided on the back side of the second polarizing plate 130 and on the front side of the display member 200 when viewed from the front surface side of the display device 10. Therefore, the distance between the transmissive region 140A and the wiring region 140C can be made relatively short, and the touch panel 140 can be downsized.

  Further, the transmissive region 140 </ b> A of the touch panel 140 is provided between the shutter liquid crystal cell 110 and the first polarizing plate 120. Therefore, the transmissive region 140 </ b> A is disposed at a relatively close position on the surface of the display device 10. Thereby, the detection sensitivity of the touch panel 140 can be maintained, and the operation position can be reliably detected.

  Since the detection sensitivity of the touch panel 140 can be maintained, a signal-to-noise ratio (SNR) can be maintained or improved. Thereby, the display apparatus 10 resistant to noise can be provided. In addition, the hovering distance can be increased.

  Further, when the transparent conductive material forming the first transparent electrode 142 and the second transparent electrode 143 is a metal formed in a mesh shape, the touch panel 140 has at least one of the transmissive region 140A and the peripheral region 140B. Even in the case where the first transparent electrode 142 and the second transparent electrode 143 are bent, the disconnection of the first transparent electrode 142 and the second transparent electrode 143 can be suppressed, and the reliability of the first transparent electrode 142 and the second transparent electrode 143 can be improved. it can. Moreover, compared with the case where a transparent conductive material is ITO (Indium Tin Oxide), the resistance value of the 1st transparent electrode 142 and the 2nd transparent electrode 143 can be reduced.

  Since the peripheral area 140B of the touch panel 140 faces the side surface of the shutter liquid crystal cell 110, a part of the non-transparent wiring 144 may exist in at least a part of the peripheral area 140B.

  Further, the peripheral region 140B and the wiring region 140C may extend only from one side of the transmissive region 140A, or may extend from two sides.

Next, another embodiment of the present invention will be described with reference to the drawings.
FIG. 9 is a block diagram showing a main configuration of a display device according to another embodiment of the present invention.
FIG. 10 is a schematic perspective view showing an arrangement relationship among the shutter portion, the display member, and the optical coupling.

  The display device 10A illustrated in FIG. 9 further includes an optical coupling 400 as compared with the display device 10 described above with reference to FIGS. As shown in FIG. 10, the optical coupling 400 is provided between the shutter unit 100 and the display member 200. The shutter unit 100 and the display member 200 are optically coupled to each other by an optical coupling 400. Examples of the optical coupling 400 include an acrylic adhesive and a double-sided adhesive tape.

  In the display device 10 </ b> A according to the present embodiment, the wiring region 140 </ b> C of the touch panel 140 is provided on the side opposite to the shutter unit 100 when viewed from the display member 200. The peripheral area 140B of the touch panel 140 passes through the side surfaces of the shutter liquid crystal cell 110 and the display member 200 and extends to the wiring area 140C. The other structure of the display device 10A is the same as that of the display device 10 described above with reference to FIGS.
