Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing the configuration of the information processing apparatus 100 according to the first embodiment of this invention. In FIG. 1, it is assumed that the information processing apparatus 100 is an apparatus capable of wireless communication, such as a mobile phone or a smartphone.

The information processing apparatus 100 illustrated in FIG. 1 includes a wireless unit 110, an antenna 120, a speaker 130, a microphone 140, a memory 150, a display unit 160, an input unit 170, and a control unit 180. The speaker 130 is an example of a notification unit.

The wireless unit 110 performs wireless communication via the antenna 120 under the control of the control unit 180.

The speaker 130 reproduces the input audio signal according to the control of the control unit 180.

The microphone 140 collects ambient sounds and outputs an audio signal of the collected sounds to the control unit 180.

The memory 150 stores various data such as various control programs executed by the control unit 180, telephone directory data, mail data, schedule data, and the like.

The display unit 160 includes an LCD (Liquid Crystal Display) 161, an LCD backlight 162, and a piezoelectric sheet 163.

The LCD 161 displays various information according to the control of the control unit 180. The LCD 161 is an example of a display unit.

The LCD backlight 162 outputs light that illuminates the display surface of the LCD 161. The LCD backlight 162 is provided with a diffusion plate that diffuses light uniformly over the entire display surface of the LCD 161. The output light is diffused by the diffusing plate and applied to the LCD 161.

The piezoelectric sheet 163 is an example of a pressure detection unit that detects pressure applied to the display surface of the LCD 161. The piezoelectric sheet 163 is disposed so as to overlap the display surface of the LCD 161, and when a pressure is applied to the display surface, a voltage signal corresponding to the pressure is output to the control unit 180. The piezoelectric sheet 163 is composed of a transparent electrode or the like and has translucency. In the present embodiment, an example in which the piezoelectric sheet 163 is used as an example of the pressure detection unit will be described, but the present invention is not limited to this. However, the pressure detection unit is a variable resistance type device in which almost no current flows when the pressure applied to the display surface is zero, and when the pressure is applied to the display surface, the current flows according to the pressure. It is preferable. By using such a device as a pressure detection unit, power consumption for pressure detection can be reduced. In addition, even if the power is in a power-saving state, pressure greater than a predetermined threshold is applied to the display surface, so that return by interruption is possible. Is possible.

The input unit 170 detects an operation input from the user, and outputs a signal corresponding to the detected operation content to the control unit 180. Specific examples of the input unit 170 include a key input circuit having key buttons and a touch or proximity of an input unit such as a finger or a stylus pen to a touch surface arranged so as to overlap the display surface. There is a touch sensor that outputs a signal corresponding to a position on a touch surface that is in contact with or in proximity. When the input unit 170 is a touch sensor, the display unit 160 also incorporates a touch sensor.

The control unit 180 receives an operation input via the input unit 170 and performs a process according to the received operation input. In addition, the control unit 180 controls the operation of the information processing apparatus 100 according to the input from the piezoelectric sheet 163.

FIG. 2 is an external perspective view of the information processing apparatus 100. In FIG. 2, the information processing apparatus 100 includes a plurality of key buttons 171 and a touch sensor 172 as the input unit 170. As described above, when a touch sensor is used as the input unit 170, the touch sensor is also incorporated into the display unit 160. In FIG. 2, in order to show the positional relationship between the components in the display unit 160, the components are described separately outside the housing of the information processing apparatus 100. In FIG. 2, the description of the speaker 130, the control unit 180, and the like is omitted.

As shown in FIG. 2, a piezoelectric sheet 163 is disposed on the LCD backlight 162. In addition, a touch sensor 172 is disposed on the piezoelectric sheet 163, and an LCD 161 as a display unit is disposed on the touch sensor 172.

In FIG. 2, the piezoelectric sheet 163 is disposed below the LCD 161, but may be disposed above the LCD 161. In addition to the LCD 161, for example, an organic EL display (Organic Electroluminescence Display) may be used as the display unit. As shown in FIG. 2, when the piezoelectric sheet 163 is provided between the LCD 161 and the LCD backlight 162, the output light of the LCD backlight 162 is hindered depending on the transparency of the piezoelectric sheet 163. The visibility of the display image on the LCD 161 may deteriorate. Since the organic EL display is a self-luminous display device, a backlight is not necessary, and the configuration of the information processing apparatus 100 can be simplified. In addition, the color and transparency of the piezoelectric sheet can be prevented from affecting the display image.

Next, the operation of the information processing apparatus 100 will be described.

First, an outline of the operation of the information processing apparatus 100 will be described.

As shown in FIG. 3, when a book or the like hits the display surface of the LCD 161 or the user bends the information processing apparatus 100 in the pocket of the pants, a large pressure is applied to the display surface, and the display unit 160 (LCD 161). May break down.

Therefore, in the information processing apparatus 100, when the pressure applied to the display surface of the LCD 161 is detected by the piezoelectric sensor 163 that is a pressure detection unit, and the detected pressure (hereinafter referred to as detection pressure) is equal to or greater than a threshold value, The user is notified by a notification process such as outputting a warning sound from the speaker 130. By doing so, it is possible to reduce the possibility that a large pressure is applied to the display surface without the user's knowledge and the display unit 160 breaks down.

Hereinafter, the details of the operation of the information processing apparatus 100 will be described with reference to the flowchart shown in FIG. In the following, it is assumed that a determination threshold value for determining whether to perform notification processing according to the pressure applied to the display surface of the LCD 161 is stored in the memory 150.

When pressure is applied to the display surface of the LCD 161, the piezoelectric sheet 163 outputs a voltage signal corresponding to the pressure to the control unit 180.

The control unit 180 has a function of AD converting the voltage signal. The control unit 180 performs AD conversion on the voltage signal output from the piezoelectric sheet 163, and reads a digitized voltage value (hereinafter referred to as a detection voltage) (step S41).

Next, the control unit 180 determines whether or not the detected voltage is greater than a determination threshold stored in the memory 150 (step S42). Here, as the determination threshold, a voltage value corresponding to a voltage signal output from the piezoelectric sheet 163 when pressure that may cause the display unit 160 to fail is applied to the display surface of the LCD 161 is set.

In the present embodiment, the voltage signal output from the piezoelectric sheet 163 is AD converted to read the detection voltage, and the detection voltage is compared with the determination threshold. However, the present invention is not limited to this. Absent. In short, since it is only necessary to determine whether or not the pressure applied to the display surface is larger than the threshold value, for example, the comparison may be performed using a comparison circuit such as a comparator.

When the detected voltage is larger than the determination threshold (step S42: Yes), the control unit 180 performs a notification process (step S43). The notification process includes a process for outputting a warning sound to the speaker 130 and a process for vibrating a vibrator (not shown in FIG. 1). After the notification process, the control unit 180 returns to the process of step S41.

When the detected voltage is larger than the determination threshold, there is a possibility that the display unit 160 is broken by applying a strong pressure. Therefore, by performing notification processing and issuing a warning to the user, it is possible to reduce the possibility that a strong pressure continues to be applied and the display unit 160 breaks down. Further, when outputting a warning sound from the speaker 130, for example, when a person is suddenly attacked on a night road, the warning sound is output by pressing the display surface of the LCD 161 with a certain force or more. Therefore, it can be used as a security alarm.

When the detected voltage is equal to or lower than the determination threshold (step S42: No), the control unit 180 determines whether or not notification processing is being performed (step S44).

If the notification process is not performed (step S44: No), the control unit 180 returns to the process of step S41.

When the notification process is being performed (step S44: Yes), since the detection voltage is equal to or lower than the determination threshold, the display unit 160 is unlikely to break down due to the pressure applied to the display surface. After stopping the notification process (step S45), the process returns to the process of step S41.

As described above, according to the present embodiment, the information processing apparatus 100 detects the pressure applied to the display surface of the LCD 161 by the piezoelectric sheet 163 that is the pressure detection unit, and notifies the user when the detected pressure exceeds the threshold value. .

Therefore, the possibility that the display unit 160 breaks down can be reduced by applying a strong pressure to the display surface of the LCD 161 as a display unit without the user's knowledge.

In general, since pressure is most easily applied near the center of the display surface, a piezoelectric sheet 163 serving as a pressure detection unit may be provided near the center of the display surface to detect pressure applied near the center of the display surface. .

Further, as described above, in the present embodiment, the touch sensor 172 is used as the input unit 170. When an operation input is detected by the touch sensor 172, even if the user unintentionally touches the touch surface lightly, the input may be detected and an erroneous operation input may be accepted. In the information processing apparatus 100 of this embodiment, the possibility of accepting an erroneous operation input as described above can be reduced by accepting an operation input based on the detection result of the pressure detection unit 180. Hereinafter, based on the detection result of the pressure detection unit 180, the operation of the information processing apparatus 100 when receiving an operation input will be described with reference to FIG. In FIG. 5, the same processes as those in FIG. 4 are denoted by the same reference numerals, and the description thereof is omitted.

After reading the detection voltage, the control unit 180 determines whether or not the detection voltage is equal to or higher than the first threshold (step S51). Here, the first threshold value is a pressure value that is applied to the display unit when the user performs an operation input by a normal touch input.

When the detected voltage is less than the first threshold (step S51: No), it is considered that pressure is not applied to the display unit by touch input, and the control unit 180 receives input from the touch sensor 172. Even if a signal indicating that is touching or approaching is output, it is assumed that there is no operation input (step S52), and the process returns to step S41.

When the detected voltage is equal to or higher than the first threshold (step S51: Yes), the control unit 180 determines whether or not the detected voltage is equal to or higher than the second threshold (step S53). Here, the second threshold value is a pressure value that may cause the display unit to fail when applied to the display unit. Therefore, the second threshold value is larger than the first threshold value.

When the detected voltage is less than the second threshold (step S53: No), the control unit 180 receives an operation input corresponding to the output signal from the touch sensor 172 (step S54).

When the detected voltage is equal to or higher than the second threshold (step S53: Yes), the control unit 180 notifies the operation input in accordance with the output signal even if a signal is output from the touch sensor 172. Processing is performed (step S55).

In this way, taking into account the detection result of the pressure detection unit 180, by accepting the operation input, a strong pressure is applied to the display unit, thereby reducing the possibility that the display unit will break down, and erroneous operation input may be performed. The possibility of being accepted can also be reduced.

(Second Embodiment)
The housing of the information processing apparatus is provided with an opening corresponding to the size of the display surface of the display unit. For this reason, when the area of the display portion increases, the area of the opening portion also increases. In recent years, information processing devices have become lighter, thinner, and smaller. When the area of the opening provided in the housing increases, the housing cannot secure rigidity and the housing itself is twisted or bent. As a result, the pressure applied to the display surface may not be detected accurately.

Therefore, in the present embodiment, the information processing apparatus is provided with a protection unit for suppressing deformation of the casing. Hereinafter, the configuration of the information processing apparatus of the present embodiment will be described with reference to FIG. In FIG. 6, the same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

FIG. 6 is a schematic cross-sectional view showing the internal configuration of the information processing apparatus 200 of the present embodiment.

As shown in FIG. 6, an opening 202 is provided in the housing 201 of the information processing apparatus 200. The opening 202 is larger than the display surface of the display unit (LCD 161 not shown in FIG. 6) of the display unit 160.

The opening 202 is provided with a protective panel 203 as a first protective part made of transparent tempered glass or transparent reinforced resin. The protective panel 203 is fixed to the opening 202 with a double-sided tape or the like having a dustproof and waterproof function. A display unit 160 is provided below the protective panel 203. In FIG. 6, the display unit 160 and the protection panel 203 are illustrated separately, but may be configured integrally. Specifically, the LCD 161 may be formed on the transparent tempered glass surface also serving as the protective panel 203 and fixed to the opening 202.

In the housing 201, a frame 204 that is fixed to the housing 201 and holds the display unit 160 is provided. A circuit board 205 on which a circuit for performing various displays by the display unit 160 is formed below the frame 204.

Further, a sheet metal 206 as a second protection unit that is fixed to the housing 201 and supports the display unit 160, the frame 204, and the circuit board 205 is provided below the circuit board 205. . Note that the sheet metal 206 is fixed to the housing 201 by abutting against a protrusion (not shown) provided in the housing 201 in FIG.

The sheet metal 206 does not need to have a larger area than the display surface, and only needs to support the display unit 160 together with the frame 204. However, it is desirable that at least a part of the sheet metal 206 is provided so as to protrude from the periphery of the display unit 160. Further, in order to prevent the metal plate 206 from losing rigidity, it is desirable to reduce the number of opening windows, and it is desirable to fold so that the end in the long side direction is not easily bent.

Since the protection panel 203 and the sheet metal 206 are fixed to the housing 201, the housing 201 is prevented from being deformed due to twisting or distortion of the housing 201 or bending.

As described above, according to the present embodiment, the information processing apparatus 200 includes the protection unit (the protection panel 203 and the sheet metal 206) in order to suppress the deformation of the casing 201 of the information processing apparatus 200.

Therefore, even when a large opening is provided in the housing 201 in order to provide the display portion, the rigidity of the housing 201 can be secured and the possibility of deformation of the housing 201 can be reduced.

In this embodiment, the example in which both the protective panel 203 and the sheet metal 206 are provided has been described. However, the present invention is not limited to this, and the rigidity of the housing 201, the display unit 160, the frame 204, and the like, Only one of the protection panel 203 and the sheet metal 206 may be provided depending on the resistance to twisting and distortion of 160, the pressure detection method, and the like.

(Third embodiment)
In the information processing apparatuses according to the first and second embodiments, the pressure applied to the display surface of the display unit is constantly detected by the pressure detection unit such as the piezoelectric sheet 163. Therefore, it is necessary to always drive the pressure detection unit, which may increase power consumption.

Therefore, in the present embodiment, the power consumption for pressure detection is reduced, and when a strong pressure is applied to the display unit, the user is notified. Hereinafter, the configuration and operation of the information processing apparatus according to the present embodiment will be described.

FIG. 7 is a block diagram illustrating a configuration of the information processing apparatus 300 according to the present embodiment. FIG. 8 is a schematic cross-sectional view showing the internal configuration of the information processing apparatus 300. In FIGS. 7 and 8, the same components as those in FIGS. 1 and 6 are denoted by the same reference numerals, and description thereof is omitted.

The information processing apparatus 300 is different from the information processing apparatus of the second embodiment in that a switch 310 is added.

As shown in FIG. 8, the switch 310 is an element that is provided between the housing 201 and the protective panel 203 and is turned on due to structural deformation when a pressure of a predetermined value or more is applied to the protective panel 203. Specific examples of the switch 310 include a variable resistor that has a large resistance value when turned off and a small resistance value when turned on. The switch 310 is supplied with power from a sub power source (not shown) different from the main power source (not shown) to which the control unit 180 and the like are supplied. When the switch 310 is turned on, it generates an interrupt signal by energization and outputs it to the control unit 180.

Although FIG. 8 shows an example in which two switches 310 are provided, the number of switches 310 may be one or three or more. In addition, a slight gap is usually provided between the protective panel 203 and the display unit 160 so that the switch 310 can be operated by structural deformation. However, when the display unit 160 and the frame 204 have a structure that can be deformed in the vertical direction, or because of the gap between the frame 204 and the circuit board 205 or between the circuit board 205 and the sheet metal 206, the switch 310 is structured. When the operation can be performed by deformation, it is not necessary to provide a gap between the protective panel 203 and the display unit 160.

In FIG. 8, the lower side of the casing 201 provided with the switch 310 is supported by the frame 204, but the configuration is such that the circuit board 205 and the sheet metal 206 are brought into contact with ribs extending from the casing 201. It is good.

Next, the operation of the information processing apparatus 300 will be described.

The information processing device has a function to turn off the main power from the normal operation state to a power saving state in which the power consumption is lower than that in the normal operation state when there is no operation input for a predetermined time or longer. There is something. When shifting to the power saving state, power supply to the pressure detection unit is normally stopped, and pressure applied to the display unit is not detected.

The transition to the power saving state is highly likely that the user is not using the information processing device and the information processing device is put in a bag or a pants pocket. In such a state, a strong pressure is applied to the display surface of the display unit without the user's knowledge, and the possibility of failure increases. On the other hand, when the user is using the information processing apparatus, generally, a strong pressure is not applied to the display surface. Therefore, if the pressure is detected during the transition to the power saving state and the pressure is not detected in the normal operation state, a strong pressure that causes the display unit 160 to fail while reducing power consumption. If it is added to, notification processing can be performed.

Hereinafter, it is assumed that the information processing apparatus 300 is in a state of shifting to the power saving state. In this state, it is assumed that a pressure equal to or higher than a predetermined value is applied to the protective panel 203. When a pressure equal to or higher than a predetermined value is applied to the protective panel 203, the switch 310 is turned on. The predetermined pressure is a pressure that is not determined to perform the notification process even when the pressure is applied to the display panel by applying the pressure to the protective panel 203.

As described above, the switch 310 is supplied with power from a sub power source different from the main power source that supplies power to the control unit 180 and the like. Therefore, even in the power saving state, when a pressure equal to or higher than a predetermined value is applied and the switch 310 is turned on, the switch 310 is energized by power supplied from the sub power supply, generates an interrupt signal, and outputs the interrupt signal to the control unit 180.

When the interrupt signal is input, the control unit 180 returns from the power saving state to the normal operation state, causes the pressure detection unit to detect the pressure, and performs the processing illustrated in FIG.

When the pressure applied to the protective panel 203 becomes a predetermined value or less, the switch 310 is turned off. When the switch 310 is turned off, no interrupt signal is input to the control unit 180. When no interrupt signal is input, the control unit 180 causes the pressure detection unit to end pressure detection.

As described above, according to the present embodiment, the information processing apparatus 300 is turned on when a pressure smaller than a pressure determined to perform the notification process and a pressure equal to or higher than a predetermined value is applied to the display surface of the display unit. When the switch 310 is turned on, the pressure applied to the display surface of the display unit is detected, and it is determined whether or not to perform notification processing according to the detected pressure.

Therefore, since it is not necessary to detect the pressure constantly applied to the display surface of the display unit, it is possible to suppress an increase in power consumption for pressure detection.

In addition, in this embodiment, although demonstrated using the example which provides the switch 310 between the housing | casing 202 and the protection panel 203, it is not restricted to this. For example, as shown in FIG. 9, a switch 310 is provided between the housing 201 and the frame 204, between the frame 204 and the circuit board 205, between the back surface of the circuit board 205 directly below the display unit 160, and the sheet metal 206. It may be provided. In short, the switch 310 may be provided at a position where the switch 310 is turned on when a pressure of a predetermined value or more is applied to the display surface of the display unit.

Alternatively, a piezoelectric element may be incorporated in the switch 310 itself, and the switch 310 may be used as a pressure detection unit instead of the piezoelectric sheet 163.

Further, instead of the switch 310, a pressure-sensitive touch sensor may be incorporated in the display unit 160 so that the pressure applied to the display unit is detected by the pressure detection unit according to the output. The pressure-sensitive touch sensor is of a variable resistance type, and has a high resistance value when no pressure is applied, and the resistance value decreases when pressure is applied. Therefore, the pressure applied to the display surface can be detected by measuring the voltage by grounding the output terminal of the pressure-sensitive touch sensor via a fixed resistor. If the detected pressure is equal to or greater than a predetermined value, an interrupt signal may be output.

In this embodiment, the return from the power saving state to the normal operation state has been described as an example, but the present invention is not limited to this. For example, when the switch 310 is turned on in the standby state where the application is selected or is waiting for execution, the normal operation state may be restored. Depending on the application to be executed, the pressure applied to the display surface may be used as part of the operation input. In this case, the control unit 180 processes the pressure detected by the pressure detection unit as part of the operation input while the application is being executed, and determines whether to perform notification processing to the user if the application is not being executed. Used to determine

(Fourth embodiment)
FIG. 10 is a schematic cross-sectional view showing the internal configuration of the information processing apparatus 400 according to the fourth embodiment of this invention. In FIG. 10, the same components as those in FIG.

The information processing apparatus 400 according to the present embodiment is different from the information processing apparatus 200 according to the second embodiment in that the piezoelectric sheet 163 is deleted and a strain sensor element 410 is provided.

The strain sensor element 410 is provided on the surface of the protective panel 203 facing the display unit 160. The strain sensor element 410 detects strain generated in the protective panel 203 and outputs the detection result to the control unit 180 (not shown).

When pressure is applied to the protective panel 203, the protective panel 203 is distorted so that the vicinity of the center of the protective panel 203 sinks, and pressure is also applied to the display surface of the display unit 160 immediately below the protective panel 203. The strain sensor element 410 detects the strain of the protective panel 203, and the control unit 180 determines whether or not to perform notification processing on the assumption that pressure according to the strain detected by the strain sensor element 410 is applied to the display surface. Judgment is made.

As described above, according to the present embodiment, the information processing apparatus 400 includes the strain sensor element 410 that detects strain generated in the protection panel 203 as a pressure detection unit, and the protection panel 203 detected by the strain sensor element 410 has It is determined whether or not notification processing is performed on the assumption that a pressure corresponding to the distortion is applied to the display surface.

As mentioned above, although this invention was demonstrated with reference to embodiment, this invention is not limited to the said embodiment. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

This application claims priority based on Japanese application 2012-193027 filed on September 3, 2012, the entire disclosure of which is incorporated herein.
