Specifically, the liquid crystal panel 2 is formed between one substrate, the other substrate arranged to face the one substrate, the liquid crystal layer interposed between the one substrate and the other substrate, and between the one substrate and the other substrate. It is provided with a display member layer that intervenes in and contributes to display, and a backlight that irradiates one substrate and the other substrate with light. Here, for convenience of explanation, the illustration of one substrate, the other substrate, the liquid crystal layer, the display member layer, and the backlight is omitted. Examples of the display member layer include a pixel electrode, an alignment film, a color filter, and the like. The drive system of the liquid crystal panel 2 may be a simple matrix drive system or an active matrix drive system.

Instead of the liquid crystal panel 2, a display panel such as a plasma panel, an organic EL panel, or electronic paper may be used. Here, the organic EL panel is a display panel using a substance that emits light when a voltage is applied. Specifically, the organic EL panel is displayed by depositing a light emitter using an organic substance such as diamine on a substrate and applying a DC voltage of 5 to 10 V. When an organic EL panel is used instead of the liquid crystal panel 2, the backlight becomes unnecessary.

The touch sensor 3 is an input device that detects a position operated by the user with a finger, a pen, or the like as an input position. As shown in FIGS. 2 and 3, the touch sensor 3 is arranged so as to face the liquid crystal panel 2 via the space S1.

Further, the lower substrate 34 has an overhanging portion 341 protruding outward from the upper substrate 32. In the present embodiment, the overhanging portion 341 projects outward from the entire outer circumference of the upper substrate 32.

When the upper detection electrode 31 and the lower detection electrode 33 are brought into contact with each other at a predetermined position, the spacer 35 causes unnecessary contact between the upper detection electrode 31 and the lower detection electrode 33 in a region other than the predetermined position. It is a member that plays a role of reducing. Examples of the constituent material of the spacer 35 include a thermosetting resin and an ultraviolet curable resin. The thermosetting resin is preferable from the viewpoint of environmental resistance, and the ultraviolet curable resin is preferable from the viewpoint of production efficiency.

Examples of the ultraviolet curable resin include acrylic resin type and epoxy resin type.

The seal member 36 is a member that plays a role of holding the upper substrate 32 and the lower substrate 34 at a predetermined interval. The sealing member 36 is located between the upper substrate 32 and the lower substrate 34, and is provided on the outer peripheral portions of the upper substrate 32 and the lower substrate 34. The sealing member 36 is, for example, an adhesive material containing a plurality of conductive particles in an insulating adhesive resin.

The vibrating body 4 is a member that plays a role of bending and vibrating the touch sensor 3 when a predetermined input operation by the user is detected. Specifically, the vibrating body 4 repeatedly expands and contracts in the short side direction of the touch sensor 3 (the left-right direction when FIG. 1 is viewed from the paper surface), thereby causing the touch sensor 3 to be in the thickness direction (hereinafter, the direction). Is referred to as "vertical direction"), and the touch sensor 3 is curved and vibrated. As will be described in detail later, the vibrating body 4 also has a role of detecting a pressing load on the touch sensor 3. The vibrating body 4 is attached to the lower surface 34b of the lower substrate 34 via an adhesive member (not shown). In the present embodiment, the vibrating body 4 is, for example, a piezoelectric element that expands and contracts based on an applied voltage, but is not limited thereto. Instead of the piezoelectric element, an electromagnetic vibrator, a spring, a motor or the like may be used.

In this embodiment, the vibrating body 4 is a piezoelectric element. Specifically, it is a unimorph type piezoelectric element. Therefore, the vibrating body 4 according to the present embodiment has the following configuration. That is, the vibrating body 4 is configured by alternately laminating electrodes and active layers, and an inactive layer is provided at a portion located near the lower surface 34b of the lower substrate 34. Here, the active layer is composed of a polarization-treated piezoelectric material. The inert layer is made of any of a non-polarized piezoelectric material, a metal material, and an insulating material. A bimorph type piezoelectric element may be used instead of the unimorph type piezoelectric element.

In the present embodiment, as shown in FIGS. 1 and 2, two vibrating bodies 4 are provided in the vicinity of both short sides of the touch sensor 3 along each short side. The arrangement position, number, etc. of the vibrating bodies 4 are not particularly limited. For example, two vibrating bodies 4 may be provided near both long sides of the touch sensor 3 along each long side, or near both long sides and short sides of the touch sensor 3. , Four may be provided along the long side and the short side of each.

The substrate 5 and the frame 6 are members that play a role of accommodating the liquid crystal panel 2. The substrate 5 has a main surface 5a. A liquid crystal panel 2 is provided on the main surface 5a of the substrate 5. That is, the liquid crystal panel 2 is provided between the lower substrate 34 and the substrate 5 in the touch sensor 3. That is, the liquid crystal panel 2 may be provided directly on the main surface 5a of the substrate 5, or may be provided on the main surface 5a of the substrate 5 via an arbitrary member such as a circuit board. The frame body 6 is provided on the main surface 5a of the substrate 5 so as to surround the liquid crystal panel 2 and the touch sensor 3. Examples of the constituent materials of the substrate 5 and the frame 6 include resins such as polycarbonate and metals such as stainless steel, aluminum, and magnesium alloys. Here, the substrate 5 and the frame 6 may be integrally formed or may be formed separately and independently.

The support 7 is a member that plays a role of supporting the touch sensor 3. In the present embodiment, the support 7 supports the touch sensor 3 on the lower surface 34b of the lower substrate 34. The support 7 is provided on the main surface 5a of the substrate 5. Specifically, the support 7 is connected to the lower surface 34b of the lower substrate 34 and the main surface 5a of the substrate 5 via the double-sided tape 71. Further, in the present embodiment, the support 7 is located at the four corners C1 to C4 of the lower substrate 34. The shape of the support 7 is, for example, a columnar shape, but may be a prismatic shape or the like. The support 7 has elasticity so as not to suppress the vibration of the touch sensor 3. Therefore, examples of the constituent material of the support 7 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

In the above description, an example in which the support 7 is connected to the lower surface 34b of the lower substrate 34 and the main surface 5a of the substrate 5 via the double-sided tape 71 has been described, but the present invention is not limited to this. For example, the support 7 may be directly connected to the main surface 5a of the substrate 5 without the intervention of the double-sided tape 71. Further, the support 7 may be connected to the lower surface 34b of the lower substrate 34 and the main surface 5a of the substrate 5 by using an arbitrary adhesive member instead of the double-sided tape 71.

Further, in the above description, an example in which the support 7 is located at the four corners C1 to C4 of the lower substrate 34 has been described, but the present invention is not limited to this. The support 7 may be located between the corners C1 and C2 and between the corners C3 and C4 in addition to the four corners C1 to C4 of the lower substrate 34.

The protrusion 8 is provided on the frame body 6. Specifically, the projecting portion 8 is provided so as to project inward so as to face the projecting portion 341 of the lower substrate 34. The frame body 6 and the projecting portion 8 may be integrally formed or may be formed separately and independently. Here, in the present embodiment, as shown in FIG. 4, the upper surface 341a of the overhanging portion 341 is connected to the lower surface 8b of the protruding portion 8 via the first variable member 9. Specifically, the first variable member 9 is connected to the lower surface 8b of the protrusion 8 and the upper surface 341b of the overhanging portion 341 via the double-sided tape 91. The first variable member 9 itself may be a deformable joining member (for example, double-sided tape).

In the present embodiment, the first variable member 9 is located between the lower surface 8b of the protruding portion 8 and the upper surface 341a of the overhanging portion 341, and is provided so as to surround the upper substrate 32. The first variable member 9 has elasticity. Examples of the constituent material of the first variable member 9 include silicone rubber, urethane rubber, urethane foam, and other rubbers. Therefore, in the electronic device X1, even if dust or water enters through the gap between the upper substrate 32 and the protrusion 8, the dust or water is separated from the touch sensor 3 by the first variable member 9. The possibility of entering the space S1 between the liquid crystal panel 2 and the liquid crystal panel 2 can be reduced. Therefore, the electronic device X1 has a certain degree of dustproofness and waterproofness. In order to further enhance the waterproof property, it is preferable to use a waterproof double-sided tape for the double-sided tape 91.

Further, a protective glass or a protective film may be provided on the upper surface 32a of the upper substrate 32 and the upper surface 8a of the protrusion 8 so as to close the gap between the upper substrate 32 and the protrusion 8.

Further, since the first variable member 9 is located between the lower surface 8b of the protruding portion 8 and the upper surface 341a of the protruding portion 341, it is possible to reduce the suppression of the bending vibration of the touch sensor 3. Can be done. That is, the first variable member 9 also changes with the bending vibration of the touch sensor 3. Although FIGS. 2 to 4 show an example in which the first variable member 9 has an elliptical shape in a cross-sectional view, the present invention is not limited to this. That is, in order to further reduce the suppression of the bending vibration of the touch sensor 3 by the first variable member 9, the first variable member 9 may be provided with a cavity 9a as shown in FIG. .. Further, in order to further reduce the suppression of the bending vibration of the touch sensor 3 by the first variable member 9, the first variable member 9 has an M-shape in cross section as shown in FIG. May be good. Further, the first variable member 9 may have a Z shape when viewed in cross section.

Further, it is preferable that the first variable member 9 is compressed and narrowed between the lower surface 8b of the protruding portion 8 and the upper surface 341a of the overhanging portion 341. Even when the user presses the upper substrate 32 toward the lower substrate 34, the first variable member 9 is compressed and narrowed, so that the first variable member 9 is sufficiently downward. It becomes possible to stretch. That is, the first variable member 9 can have a margin. As a result, the possibility that the touch sensor 3 comes off from the protrusion 8 can be reduced.

As described above, the electronic device X1 has a certain degree of dustproofness and waterproofness, and can transmit a sufficient tactile sensation to the user.

Further, as shown in FIGS. 2 to 4, it is preferable that the height position of the upper surface 32a of the upper substrate 32 and the height position of the upper surface 8a of the protrusion 8 are substantially the same. Therefore, in the present embodiment, as shown in FIG. 4, the thickness L1 of the upper substrate 32 is larger than the thickness L2 of the lower substrate 34. If the height position of the upper surface 32a of the upper substrate 32 and the height position of the upper surface 8a of the protrusion 8 are substantially the same, one main surface of the electronic device X1 becomes a flat surface, and the design of the electronic device X1 is improved. To do.

Next, an operation example of the electronic device X1 will be described with reference to FIG. 7.

In the following, an operation example of the electronic device X1 in the case of transmitting the feeling of pressing to the user among the tactile sensations will be described, but the electronic device X1 has a feeling of tracing, a feeling of touch, etc. other than the feeling of pressing. Of course, it can also be applied when transmitting various tactile sensations.

As shown in FIG. 7, when the user presses the touch sensor 3, the vibrating body 4 detects the pressing load on the touch sensor 3 (Op1). Here, the load detection function of the vibrating body 4 will be described. That is, when the user presses the touch sensor 3, the touch sensor 3 curves downward. When the touch sensor 3 bends downward, the vibrating body 4 also bends downward. That is, the amount of curvature of the vibrating body 4 changes according to the pressing load on the touch sensor 3. In the present embodiment, since the vibrating body 4 is a piezoelectric element, it can be converted into a voltage according to the amount of curvature. As a result, the pressing load on the touch sensor 3 can be detected by the vibrating body 4. In the above description, an example in which the load detection function is realized by the vibrating body 4 has been described, but the present invention is not limited to this, and for example, a load sensor such as a strain sensor may be used.

Then, the tactile transmission driver (not shown) determines whether or not the pressing load detected by Op1 is equal to or greater than the threshold value when the input operation by the user is a pressing operation on the input object displayed on the display screen. (Op2). The tactile transmission driver is provided, for example, on an FPC (Flexible Printed Circuit) connected to the touch sensor 3 together with a touch panel driver that controls the touch sensor 3.

Then, if the tactile transmission driver determines that the pressing load detected in Op1 is equal to or greater than the threshold value (YES in Op2), the vibrating body 4 expands and contracts in the short side direction of the touch sensor 3 (Op3). Then, the touch sensor 3 bends and vibrates in the vertical direction due to the vibrating body 4 that is expanded and contracted in Op3 (Op4). As a result, the feeling of pressing is transmitted to the user who presses the touch sensor 3. On the other hand, if the tactile transmission driver determines that the pressing load detected in Op1 is less than the threshold value (NO in Op2), the process of FIG. 7 ends.

Next, the mobile terminal P1 provided with the above-mentioned electronic device X1 will be described with reference to FIG.

FIG. 8 is a perspective view showing a schematic configuration of the mobile terminal P1 according to the present embodiment. As shown in FIG. 8, the mobile terminal P1 is, for example, a mobile phone, a smartphone, a PDA (Personal Digital Assistant), or the like, and includes the above-mentioned electronic device X1, a voice input unit 101, a voice output unit 102, and a key. It includes an input unit 103 and a housing 104.

The voice input unit 101 is composed of, for example, a microphone or the like, and a user's voice or the like is input. The voice output unit 102 is composed of a speaker or the like, and outputs voice or the like from the other party. The key input unit 103 is composed of, for example, mechanical keys. The key input unit 103 may be an operation key displayed on the display screen. The housing 104 is a member that plays a role of accommodating the electronic device X1, the voice input unit 101, the voice output unit 102, and the key input unit 103.

In addition, the mobile terminal P1 may be provided with a digital camera function unit, a tuner for one-segment broadcasting, a short-range wireless communication unit such as an infrared communication function unit, various interfaces, etc., depending on the required functions. The illustration and description of the details of the above will be omitted.

Since the mobile terminal P1 is equipped with the electronic device X1, it is possible to transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness.

In the above description, an example in which the mobile terminal P1 is provided with the voice input unit 101 has been described, but the present invention is not limited to this. That is, the mobile terminal P1 does not have to be provided with the voice input unit 101.

Further, in the above description, an example in which the mobile terminal P1 includes a housing 104 for accommodating the electronic device X1 has been described, but the present invention is not limited to this. A mobile terminal in which the base 5 and the frame 6 in the electronic device X1 serve as a housing may be used without providing the housing 104 separately and independently.

[Embodiment 2] FIG. 9 is an enlarged cross-sectional view showing a schematic configuration of an electronic device X2 according to the present embodiment. In FIG. 9, the same reference numerals are added to the configurations having the same functions as those in FIG. 4, and detailed description thereof will be omitted.

As shown in FIG. 9, in the electronic device X2, the second variable member 10 is provided between the upper substrate 32 and the protrusion 8. The second variable member 10 has elasticity like the first variable member 9. Examples of the constituent material of the second variable member 10 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

In the present embodiment, since the gap between the upper substrate 32 and the protrusion 8 is filled by the second variable member 10, dust or water may infiltrate between the upper substrate 32 and the protrusion 8. Can be reduced. Further, since the second variable member 10 is provided in addition to the first variable member 9, dust or water enters the space S1 between the touch sensor 3 and the liquid crystal panel 2 as compared with the electronic device X1. The possibility can be further reduced. Further, since the second variable member 10 is provided between the upper substrate 32 and the protruding portion 8, it is possible to reduce the suppression of the bending vibration of the touch sensor 3.

It is preferable that the height position of the upper surface 32a of the upper substrate 32, the height position of the upper surface 8a of the protrusion 8, and the height position of the upper surface 10a of the second variable member 10 are substantially the same. If the height position of the upper surface 32a of the upper substrate 32, the height position of the upper surface 8a of the protrusion 8 and the height position of the upper surface 10a of the second variable member 10 are substantially the same, it is the main component of the electronic device X2. The surface becomes a flat surface, improving the design of the electronic device X2.

As described above, the electronic device X2 has excellent dustproof and waterproof properties as compared with the electronic device X1, and can transmit a sufficient tactile sensation to the user.

In the above description, an example in which the first variable member 9 and the second variable member 10 are formed separately and independently has been described, but the present invention is not limited to this. The first variable member 9 and the second variable member 10 may be integrally formed. In this case, a variable member is provided between the upper substrate 32 and the protruding portion 8 and between the protruding portion 8 and the overhanging portion 341.

[Embodiment 3] FIG. 10 is a plan view showing a schematic configuration of an electronic device X3 according to the present embodiment. FIG. 11 is a cross-sectional view taken along the cutting lines III-III shown in FIG. FIG. 12 is an enlarged view of the support 11. Note that, in FIGS. 10 and 11, the same reference numerals are added to the configurations having the same functions as those in FIGS. 1 and 2, and detailed description thereof will be omitted.

As shown in FIGS. 10 to 12, the electronic device X3 includes a support 11 instead of the support 7 described in the first embodiment. The diameter M1 of the surface 11a in contact with the lower surface 34b of the lower substrate 34 of the support 11 is smaller than the diameter M2 of the surface 11b in contact with the main surface 5a of the substrate 5 of the support 11. Specifically, the support 11 has a so-called tapered shape in which the diameter gradually increases from the lower surface 34b of the lower substrate 34 toward the main surface 5a of the substrate 5. By configuring the support 11 in this way, the degree of restraint of the touch sensor 3 by the support 11 can be reduced. Therefore, the electronic device X3 can transmit a sufficient tactile sensation to the user as compared with the electronic device X1 described in the first embodiment.

The "surface diameter" referred to above means the diameter of the circle when the surface is circular in plan view, and when the surface is polygonal in plan view, the said. Means the diagonal of a polygon.

As described above, the electronic device X3 has a certain degree of dustproofness and waterproofness, and can transmit a sufficient tactile sensation to the user as compared with the electronic device X1.

Examples of the constituent material of the third variable member 13 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

Although the first variable member 12 has some elasticity, it is made of double-sided tape, so that the bending vibration of the touch sensor 3 may be suppressed to some extent. However, in the present embodiment, since the third variable member 13 is provided between the frame body 6 and the protruding portion 8 in addition to the first variable member 12, the third variable member 13 causes the curved vibration of the touch sensor 3. Can be reduced.

As described above, the electronic device X4 has a certain degree of dustproofness and waterproofness, and can transmit a sufficient tactile sensation to the user.

In the first to fourth embodiments, an example of the touch sensor 3 including the upper substrate 32 that functions as the operation plate and the lower substrate 34 that functions as the support plate has been described, but the present invention is not limited to this.

Examples of the display panel having the function of the touch sensor include a display panel having a built-in optical sensor having a position detection function.

Further, in the first embodiment, the example of the mobile terminal P1 provided with the electronic device X1 has been described, but any of the electronic devices X2 to X4 may be adopted instead of the electronic device X1. Further, the first to fourth embodiments may be combined as appropriate.

Further, in the first to fourth embodiments, examples of applying the electronic devices X1 to X4 to the tactile transmission technique have been described, but the present invention is not limited to this.
