Description

  The present invention relates to an input device and an electro-optical device with the input device including the input device.

  Electronic devices such as mobile phones, car navigation systems, personal computers, ticket machines, and bank terminals use an input device having a touch panel on the surface of a liquid crystal device or the like. In such an input device, an image display of the liquid crystal device is used. Information can be input by operating a switch button displayed in the area. In such an input device, unlike a mechanical input device that presses a key, there is a tendency that it is difficult to feel the operated feeling.

  Therefore, a technique has been proposed in which the user can easily recognize that the touch panel has been vibrated and the touch panel has been operated (see Patent Document 1).

  More specifically, in the input device described in Patent Document 1, the touch panel is supported by the casing via a cushion, and when the casing is closed, the entire mobile phone on which the touch panel is mounted is vibrated, When the housing is opened, only the touch panel is vibrated.

JP 2008-17327 A

  However, in order to allow the touch panel to vibrate, it is necessary to secure a gap between the touch panel and the casing over the entire circumference of the touch panel, so that foreign matter such as moisture easily enters from the gap between the touch panel and the casing. . Therefore, the configuration described in Patent Document 1 has a problem that foreign matter cannot be prevented from entering the inside.

  In view of the above problems, an object of the present invention is to provide an input device and an electro-optical device with an input device that can prevent entry of foreign matters such as moisture into the inside even when the touch panel can be vibrated. There is.

In order to solve the above problems, an input device according to the present invention, a touch panel, and can be imparted oscillating member vibration in motor touch panel, at a gap between the outer peripheral end portion of the motor touch panel around the touch panel A translucent flexible film that has an arranged frame body and an easily deformable portion that enters the gap and closes the gap, and is applied across the input operation surface of the touch panel and the input operation surface side of the frame body. with a sex film, a flexible film, busy with data touch panel is in a state of being supported by the oscillatably frame in contact with the touch panel and the frame, between the gap over the entire circumference of the motor touch panel Gu

In order to vibrate the touch panel, a gap is provided between the touch panel and the frame. However, the gap may be supported by the frame so that the touch panel can vibrate all around the touch panel. It is blocked by a flexible film . For this reason, even when the touch panel can be vibrated, foreign matter such as moisture can be prevented from entering the inside. When the touch panel is displaced, the flexible film can be deformed following the displacement of the touch panel. In addition, since the touch panel is supported and foreign matter is prevented from entering by a common member, the configuration can be simplified.

In the present invention, data touch panel is a capacitive touch panel, a switch for detecting the pressure on the data touch panel, oscillation member, employs a configuration which vibrates the motor touch panel when the motor touch panel is pressed can do. Capacitance type input devices have the advantage that they can be input even if they are not pressed or approached, but they cannot be distinguished from malfunctions without confirming the input without pressing any other button. There is. However, in the present invention, when the touch panel is pressed, the switch detects the press, and the oscillation member vibrates the touch panel. For this reason, it is possible to determine that the pressing operation on the touch panel is the confirmation of input, and it is possible to make the user recognize that the confirmation operation has been performed by the vibration of the touch panel.

In the present embodiment, the second translucent conductive film 4b is also made of a polycrystalline ITO film, like the first translucent conductive film 4a. The metal film 4c is made of an alloy of silver, palladium, copper, or the like. The first surface 20a of the substrate 20 may be provided with a light-transmitting base protective film made of a silicon oxide film or the like on the entire surface. In this case, the first light-transmitting property is formed on the base protective film. The conductive film 4a, the interlayer insulating film 214, and the second light transmissive conductive film 4b are sequentially stacked.

  In the capacitance-type input device 1 of the present embodiment, the first light-transmissive conductive film 4a is first formed as a plurality of rhombus regions in the input region 2a. The pad portions 211a and 212a (large area portion) of the first electrode 211 and the second electrode 212) are configured. These pad portions 211a and 212a are alternately arranged in the X direction and the Y direction. In the plurality of pad portions 211a, adjacent pad portions 211a in the X direction (first direction) are connected via a connecting portion 211c, and the pad portion 211a and the connecting portion 211c extend in the X direction.

For this reason, the second electrode 212 extends in the Y direction while being electrically connected in the Y direction. Note that the relay electrode 215 overlaps the connecting portion 211c with the interlayer insulating film 214 interposed therebetween, so there is no possibility of short circuit.

(Input position detection method)
In the input device 1 configured as described above, when a position detection signal in the form of a rectangular pulse is output to the input position detection electrode 21, if no capacitance is parasitic on the input position detection electrode 21, the input position detection electrode 21 A signal having the same waveform as the applied position detection signal is detected. On the other hand, if a capacitance is parasitic on the input position detection electrode 21, a waveform distortion due to the capacitance occurs. Therefore, it is detected whether or not the capacitance is parasitic on the input position detection electrode 21. be able to. Therefore, when the finger approaches one of the plurality of input position detection electrodes 21, the input position detection electrode 21 that is in proximity to the finger has a capacitance corresponding to the capacitance generated between the finger. Since it increases, it is possible to identify the electrode that the finger is close to.

(Configuration for input confirmation)
FIG. 5 is an explanatory diagram schematically illustrating the configuration of the cover 90, the frame, and the like used in the electro-optical device 100 with an input device according to the first embodiment of the present invention. , (C), (d) are plan views of the cover 90, the frame, etc., a cross-sectional view of the cover 90, the frame, etc. cut along the line C1-C1 ′, and a cross section of the cover 90, the frame, etc. It is explanatory drawing which expands and shows a structure, and explanatory drawing which shows a mode that the cover 90 (touch panel 2) was pressed.

  In this embodiment, after the input to the touch panel 2 shown in FIG. 3A, the touch panel 2 is pressed when confirming the input content. As a result, as shown in FIG. 3B, the touch panel 2 is slightly lowered, and then the touch panel 2 vibrates. Therefore, the user can clearly recognize that the input has been confirmed.

  For the purpose of performing such an operation, in the electro-optical device 100 with an input device according to the present embodiment, the input device 1 includes a bottom 3011 of the first housing 3010 shown in FIG. A dome-shaped switch 31 and a rubber cushion 36 are provided between the bottom 531 of the frame 53. In this embodiment, the switch 31 is provided at the approximate center between the bottom 3011 of the first housing 3010 and the bottom 531 of the frame 53, and the cushion 36 is provided between the bottom 3011 of the first housing 3010 and the frame 53. It is provided at the end between the bottom 531. Here, the switch 31 includes a rubber sheet layer and can be deformed in the thickness direction. In addition, the input device 1 includes two oscillation members 33 made of piezoelectric vibrators at the bottom 531 of the frame 53. Here, the switch 31 is a pressure-sensitive resistor element and is not in contact with the first housing 3010. Accordingly, when the touch panel 2 is pressed and the switch 31 is deformed between the bottom 3011 of the first housing 3010 and the bottom 531 of the frame 53, the switch 31 outputs a signal indicating that the touch panel 2 has been pressed. When the signal output is generated, the oscillation member 33 applies vibration to the touch panel 2 via the image generation device 5. At that time, the image generation device 5 also vibrates integrally with the touch panel 2.

  In addition, the input device 1 includes a plate-like frame body 95 with a gap 98 between the outer peripheral end of the touch panel 2 as shown in FIGS. 3 (a), 5 (a), and 5 (b). The frame body 95 is fixed to the upper plate portion 3012 of the first housing 3010 shown in FIG.

  Further, as shown in FIGS. 3A, 5B, and 5C, the input device 1 is in contact with the touch panel 2 and the frame body 95 and is supported by the frame body 95 so that the touch panel 2 can vibrate. The flexible member 96 to be in a state is provided, and the flexible member 96 closes the gap 98 over the entire circumference of the touch panel 2. More specifically, the frame 95 includes a rectangular opening 950 having a shape similar to or substantially similar to the planar shape of the cover 90 constituting the input operation surface of the touch panel 2, and the inside of the opening 950 is inside the opening 950. A cover 90 of the touch panel 2 is disposed. Therefore, a rectangular gap 98 exists between the outer peripheral end of the cover 90 and the inner peripheral end of the opening 950 provided in the frame body 95, and the touch panel 2 is displaced by the presence of the gap 98. Is possible.

  In the present embodiment, the flexible member 96 is a translucent flexible member that is pasted by the adhesive layer 969 across the input operation side surface of the cover 90 and the frame body 95 of the touch panel 2. And a rubber flexible packing 962 provided in the gap 98. In such a flexible member 96, the flexible packing 962 is in contact with the outer peripheral end of the touch panel 2 and the inner peripheral end of the opening 950 of the frame body 95 over the entire periphery of the touch panel 2 to block the gap 98. . Further, the flexible film 961 is stuck to the cover 90 and the frame body 95 so as to straddle the gap 98 to block the gap 98.

  For this reason, in the input device 1 and the electro-optical device 100 with the input device according to the present embodiment, foreign matter such as moisture such as sweat and rain can be prevented from entering the inside through the gap 98. As shown in FIGS. 3B and 5D, when the touch panel 2 is pressed, the touch panel 2 is displaced downward, and when the press is performed, the touch panel 2 can be vibrated. .

  Here, since the frame body 95 is made of a translucent material, a light shielding layer 95 a is formed in the same manner as the cover 90. The frame body 95 is made of the same translucent material as the cover 90. In this embodiment, the frame body 95 and the cover 90 are both made of glass. The frame 95 having such a configuration is formed at the same time when the cover 90 is cut out from a large glass plate. For example, when the cover 90 is cut out from a large glass plate by etching, if the glass plate is etched in a state where the cover 90 and the frame body 95 are cut out with an etching mask in the large glass plate, the outer portion of the frame 95 Since the portion between the cover 90 and the frame body 95 is removed by etching, the frame body 95 and the cover 90 can be formed simultaneously from the glass plate. In addition, a rectangular opening 950 having a shape similar to or substantially similar to the planar shape of the cover 90 can be reliably formed in the frame 95.

(Main effects of this form)
As described above, in the input device 1 and the electro-optical device 100 with the input device according to the present embodiment, a machine that presses a switch key to vibrate the touch panel 2 by the oscillation member 33 to make the user recognize the vibration of the touch panel 2. A feeling similar to that of the input device can be obtained. In particular, the touch panel 2 of this embodiment is a capacitive touch panel, but the input device 1 is convenient because the touch panel 2 is vibrated by the oscillation member 33 when the touch panel 2 is pressed. In other words, the capacitance type input device 1 has an advantage that the input can be performed even if it is not pressed or just approached. On the other hand, if any other button is not pressed, the input is confirmed and the malfunction is discriminated. In this embodiment, when the touch panel 2 is pressed, the switch 31 detects the pressing, and the oscillation member 33 vibrates the touch panel 2. For this reason, it is possible to determine that the pressing operation on the touch panel 2 is the confirmation of input, and when the touch panel 2 vibrates, the user can be made aware that the confirmation operation has been performed.

  In this embodiment, since the touch panel 2 is vibrated as described above, there is a gap 98 between the touch panel 2 and the frame body 95, but the gap 98 extends over the entire circumference of the touch panel 2. Is closed by a flexible member 96 that is supported by the frame body 95 so as to vibrate. For this reason, even when the touch panel 2 can be vibrated, foreign matter such as moisture can be prevented from entering the inside. In addition, since the support of the touch panel 2 and the prevention of foreign matter intrusion are performed by a common member (flexible member 96), the configuration can be simplified.

  In addition, in this embodiment, as the flexible member 96, the translucent flexible film 961 attached by the adhesive layer 969 across the input operation side surfaces of the cover 90 and the frame body 95, and the gap 98 Since the rubber-made flexible packing 962 provided on the touch panel 2 is used, there is an advantage that the touch panel 2 can be reliably supported so as to be able to vibrate and the gap 98 can be reliably closed. In addition, since the flexible film 961 is bent and the flexible packing 962 is twisted and the flexible packing 962 is not compressed and deformed, there is an advantage that the touch panel 2 is easily displaced.
