[0009] [Embodiment 1] (Display device configuration) FIG. 1 is a plan view showing an example of the configuration of a display device according to one embodiment of the present disclosure, along with a user looking at the display device. FIG. 2 is a schematic diagram showing another example of the configuration of a display device according to one embodiment of the present disclosure, along with a user looking at the display device. As shown in FIGS. 1 and 2, a display device 1 according to a first embodiment of the present disclosure includes a display panel 10 having a display area 12 and a frame area 14 surrounding the display area 12, a proximity sensor 30 including either a capacitance sensor 32 (see FIG. 1) or an infrared sensor 34 (see FIG. 2), and a touch sensor 40 overlapping the display area 12 in a plan view.

[0010] 3 is a partial cross-sectional view showing an example of the configuration of the display device shown in FIG. 1. As shown in FIGS. 1 and 3, the capacitance sensor 32 has multiple sensor electrodes 32A that overlap the display area 12 in a planar view and can detect the proximity of an operator to each sensor electrode 32A. The capacitance sensor 32 may be a distance measurement sensor that measures the distance from each of the multiple sensor electrodes 32A to an object based on a change in capacitance between the sensor electrode 32A and the object. The object may be, for example, the user's body or hand, or a wall or ceiling of a room.

[0011] The display area 12 of the display panel 10 has a first display area 12A that displays a first image IMG1 and a second display area 12B that displays a second image IMG2. The display device 1 is provided with a light-shielding pattern 20 that is arranged so that a first user U1 viewing the display panel 10 from a first side (the left side in FIG. 1) can see the first image IMG1 but not the second image IMG2, and so that a second user U2 viewing the display panel 10 from a second side (the right side in FIG. 1) opposite the first side can see the first image IMG1 but not the second image IMG2. The multiple sensor electrodes 32A of the capacitance sensor 32 are arranged to overlap with the light-shielding pattern 20 in a planar view.

[0012] The light-shielding pattern 20 may include a plurality of first light-shielding portions 22 and one or more second light-shielding portions 24. A plurality of sensor electrodes 32A may be arranged one by one above (or below) the plurality of first light-shielding portions 22, and an electrically floating dummy electrode 36 may be arranged above (or below) the second light-shielding portion 24.

[0013] FIG. 4 is a schematic diagram showing an example of zone division by the infrared sensor shown in FIG. 2. As shown in FIG. 4, the infrared sensor 34 divides the display area 12 into multiple zones ZN and can detect the operator's proximity to each zone ZN. The infrared sensor 34 may divide an area including the display area 12 and the frame area 14 into multiple zones ZN and can detect the operator's proximity to each zone ZN. The infrared sensor 34 may be a distance measuring sensor that measures the distance from each of the multiple zones ZN to an object based on infrared light reflected from the object through that zone ZN. The object may be, for example, the user's body or hand, or a wall or ceiling of a room.

[0014] 5 to 7 are plan views showing various examples of the arrangement of the infrared sensor shown in Fig. 2. As shown in Fig. 5, the infrared sensor 34 may be arranged on the display area 12 side near the boundary between the display area 12 and the frame area 14, with the display area 12 cut out. As shown in Fig. 6, the infrared sensor 34 may be arranged within the display area 12. As shown in Fig. 7, the infrared sensor 34 may be arranged on the frame area 14 side near the boundary between the display area 12 and the frame area 14.

[0015] In any of the above configurations, the first user U1 and / or the second user U2 can operate the display device 1 via the touch sensor 40. In the present disclosure, a user who is attempting to operate and / or is operating the display device 1 via the touch sensor 40 is referred to as an "operator."

[0016] According to the above configuration, the proximity sensor 30 is a capacitance sensor 32 that overlaps the display area 12 in plan view, or an infrared sensor 34 that is capable of multi-zone detection. Therefore, compared to a configuration in which multiple sensors that are not capable of multi-zone detection are arranged in the frame area (for example, the configuration disclosed in Japanese Patent Application Laid-Open No. 2009-241707), the frame of the display device 1 can be made narrower.

[0017] In a configuration in which multiple sensors that are not capable of multi-zone detection are arranged in the frame area (for example, the configuration disclosed in JP 2009-241707 A), the wider the display area, the more difficult it becomes to detect proximity to the center of the display area, making it difficult to enlarge the screen.

[0018] On the other hand, according to the configuration of the present disclosure, the proximity sensor 30 of the present disclosure can detect proximity throughout the entire display area 12. The proximity sensor 30 measures the distance from each sensor electrode 32A or each zone ZN to an object. The multiple sensor electrodes 32A are located within the display area 12 in a planar view, and the multiple zones ZN cover the entire display area 12 in a planar view. Therefore, even if the display area 12 is large, proximity to the center of the display area 12 can be detected, allowing the display device 1 to have a larger screen.

[0019] 1 and 2, the display panel 10 is capable of single-view display, in which the first user U1 and the second user U2 see the same image by making the second image IMG2 the same as the first image IMG1. The display panel 10 is also capable of multi-view display, in which the first user U1 sees the first image IMG1 and the second user U2 sees the second image IMG2, which is different from the first image IMG1. Multi-view display includes dual-view display.

[0020] (Configuration of control unit) 8 is a functional block diagram showing an example of the configuration of a display device according to an aspect of the present disclosure. As shown in FIG. 8, the display device 1 according to the first embodiment of the present disclosure further includes a control unit 50.

[0021] The control unit 50 includes a proximity receiving unit 51 that receives proximity information from the proximity sensor 30, a touch receiving unit 52 that receives touch information from the touch sensor 40, an operator identification unit 53 that identifies, based on the proximity information, whether the operator is a first user U1 viewing the display panel 10 from a first side or a second user U2 viewing the display panel 10 from a second side opposite the first side, and a touch processing unit 54 that, when the operator is identified as the first user U1, executes a first process corresponding to the touch information, and, when the operator is identified as the second user U2, executes a second process corresponding to the touch information, the second process being at least partially different from the first process.

[0022] According to the above configuration, it is possible to distinguish between touch operations by the first user U1 and touch operations by the second user U2 and provide different processes for them. Furthermore, since erroneous detection of the touch sensor 40 due to noise is not accompanied by proximity information indicating the proximity of the operator, it is possible to eliminate erroneous detection of the touch sensor 40.

[0023] The proximity receiving unit 51 may be a simple port that sends the proximity information from the proximity sensor 30 directly to the operator identifying unit 53, or may perform some processing on the proximity information and send the processed proximity information to the operator identifying unit 53. The proximity receiving unit 51 may perform processing such as analog-to-digital conversion of the proximity information or determining whether the proximity information exceeds a threshold. If the proximity sensor 30 is a capacitive sensor 32, the proximity information may indicate the distance from each of the multiple sensor electrodes 32A to the target. If the proximity sensor 30 is an infrared sensor 34, the proximity information may indicate the distance from each zone ZN to the target. Arrangement information indicating the arrangement of the multiple sensor electrodes 32A or the multiple zones ZN may be recorded in a storage medium accessible by the control unit 50.

[0024] The operator identifying unit 53 receives proximity information from the proximity receiving unit 51 and identifies whether the operator is the first user U1 or the second user U2 based on the proximity information and the position information. The operator identifying unit 53 may also identify the presence or absence of an operator based on the proximity information and the position information. The operator identifying unit 53 sends operator information indicating the operator to the touch processing unit 54.

[0025] The touch receiving unit 52 may be a simple port that sends touch information from the touch sensor 40 directly to the touch processing unit 54, or may perform some processing on the touch information and send the processed touch information to the touch processing unit 54. The touch information may indicate the position where the operator touched the display device 1.

[0026] The touch processing unit 54 determines whether the operator is the first user U1 or the second user U2 based on the operator information from the operator identification unit 53. The touch processing unit 54 executes a first process for a touch operation by the first user U1, and executes a second process for a touch operation by the second user U2.

[0027] The control unit 50 may include a drive control unit 60, which may include a display panel control unit 62 that controls the display panel 10, a proximity sensor control unit 64 that controls the proximity sensor 30, and a touch sensor control unit 66 that controls the touch sensor 40.

[0028] The display panel control unit 62 may control the display panel 10 to (i) perform single view when the operator is not performing a touch operation, i.e., when the touch acceptance unit 52 is not accepting touch information, and (ii) perform multi-view when the operator is performing a touch operation, i.e., when the touch acceptance unit 52 accepts touch information. To eliminate erroneous detection by the touch sensor 40, multi-view may be performed when the operator identification unit 53 identifies the presence of an operator and the touch acceptance unit 52 accepts touch information, and single view may be performed in other cases. By performing single view when no touch operation is performed, the display device 1 can reduce the calculation load of the control unit 50. By performing multi-view when a touch operation is performed, the display device 1 can display an image corresponding to the touch operation to the operator and simultaneously display a different image to a non-operator.

[0029] Conversely, the display panel control unit 62 may control the display panel 10 to perform multi-view when the operator is not performing a touch operation, and to perform single-view when the operator is performing a touch operation.

[0030] Alternatively, the display panel control unit 62 may control the display panel 10 to (i) perform single view when the user is away from the display device 1, i.e., when the operator identification unit 53 identifies that the operator is absent based on the proximity information, or (ii) perform multi-view when the user is close to the display device 1, i.e., when the operator identification unit 53 identifies that the operator is present based on the proximity information. By performing single view when no one is close to the display area 12, the display device 1 can reduce the calculation load of the control unit 50. By performing multi-view when someone is close to the display area 12, the display device 1 can display an image that prompts the close person to perform a touch operation, and simultaneously display a different image to a non-close person.

[0031] Conversely, the display panel control unit 62 may control the display panel 10 to perform multi-view when the user is away from the display device 1 and to perform single-view when the user is close to the display device 1.

[0032] The first process and the second process by the touch processing unit 54 may differ in the instructions given to the display panel control unit 62. For example, the first process may include switching the first image IMG1, while the second process may include switching the second image IMG2. This allows the first user U1 to switch the first image IMG1 by a touch operation, and the second user U2 to switch the second image IMG2 by a touch operation.

[0033] Additionally or alternatively, the first process and the second process may differ in other respects, for example, in one or more of the commands to the proximity sensor control unit 64, the commands to the touch sensor control unit 66, and the commands to external devices such as speakers and air conditioning equipment.

[0034] (Operation of operator identification unit) Fig. 9 is a flow chart showing an example of the operation of the operator identifying unit shown in Fig. 8. Fig. 10 is a diagram showing an example of the distance from each zone to an object measured by the infrared sensor when no one is approaching the display area. Fig. 11 is a diagram showing an example of the distance from each zone to an object measured by the infrared sensor when an operator brings their hand close to the first side (left side) of the display area. Fig. 12 is a diagram showing an example of the distance from each zone to an object measured by the infrared sensor when an operator brings their hand close to the second side (right side) of the display area.

[0035] 10 to 12, the unit of distance is mm, and the proximity sensor 30 is an infrared sensor 34. The multiple zones ZN include a first zone group BLK1 located on a first side (left side) of the center of the display area 12, and a second zone group BLK2 located on a second side (right side) of the center of the display area 12. A threshold value (distance threshold value) is set for each zone ZN to determine that an object is close to that zone ZN.

[0036] The number of zones ZN in the first zone group BLK1 whose measured distance is equal to or less than the distance threshold is referred to as the first number of interest, and the number of zones ZN in the second zone group BLK2 whose measured distance is equal to or less than the distance threshold is referred to as the second number of interest. Thresholds (number thresholds) for the first number of interest and the second number of interest are set for each of the first zone group BLK1 and the second zone group BLK2.

[0037] In the operational example described in this section, the distance threshold is 250 mm for all zones ZN, and the number threshold is 4 for both the first zone group BLK1 and the second zone group BLK2.

[0038] 9, the operator identifying unit 53 outputs, by default, operator information "No_Detect" indicating that no operator is present and that neither the first user U1 nor the second user U2 is the operator (step S10). This reduces the chance of the touch processing unit 54 erroneously executing the first process or the second process.

[0039] When the operator identifying unit 53 outputs "No_Detect", it calculates a first number of items of interest and a second number of items of interest, and determines whether the first number of items of interest is greater than the second number of items of interest (step S20).

[0040] If the first number of items of interest is greater than the second number of items of interest (Yes in step S20), it is then determined whether the first number of items of interest is greater than the number threshold (step S30). If the first number of items of interest is greater than the number threshold (Yes in step S30), the operator identification unit 53 outputs operator information “LeftSide_Detect” indicating that an operator is present and that the first user U1 is the operator (step S32).

[0041] For example, when the operator places his / her hand close to the first side of the display area 12 as shown in Fig. 11, the first number of objects of interest is 8 and the second number of objects of interest is 2. In this case, both the first number of objects of interest > the second number of objects of interest and the first number of objects of interest > the number threshold are satisfied, and the operator identifying unit 53 outputs "LeftSide_Detect".

[0042] If the first number of targets≦the second number of targets is true (No in step S20), it is then determined whether the second number of targets is greater than the number threshold (step S40). If the second number of targets is greater than the number threshold (Yes in step S40), the operator identification unit 53 outputs operator information “RightSide_Detect” indicating that an operator is present and that the second user U2 is the operator (step S42).

[0043] For example, when the operator places his / her hand close to the second side of the display area 12 as shown in Fig. 12, the first number of objects of interest is 3 and the second number of objects of interest is 8. In this case, both the first number of objects of interest <= the second number of objects of interest and the second number of objects of interest > the number threshold are satisfied, and the operator identifying unit 53 outputs "RightSide_Detect".

[0044] If the result is No in step S30 or step S40, both the first number of interest and the second number of interest are equal to or less than the number threshold value. Therefore, the operator identifying unit 53 returns to step S10 and continues to output "No_Detect."

[0045] For example, when the user's hand is removed from the display area 12 as shown in FIG. 10, both the first number of objects of interest and the second number of objects of interest are 0, and the operator identifying unit 53 outputs "No_Detect."

[0046] While outputting "LeftSide_Detect", the operator identifying unit 53 calculates the sum of the first number of interest and the second number of interest, and determines whether the sum of the first number of interest and the second number of interest is greater than 0 (step S50). If the first number of interest + the second number of interest > 0 is established (Yes in step S50), the operator identifying unit 53 returns to step S32 and continues to output "LeftSide_Detect".

[0047] When outputting "RightSide_Detect", the operator identifying unit 53 similarly calculates the sum of the first number of targets and the second number of targets, and determines whether the sum of the first number of targets and the second number of targets is greater than 0 (step S60). If the relationship "first number of targets + second number of targets > 0" holds (Yes in step S60), the operator identifying unit 53 returns to step S42 and continues to output "LeftSide_Detect".

[0048] If the result is No in step S50 or step S60, both the first number of interest and the second number of interest are 0. Therefore, the operator identifying unit 53 returns to step S10 and outputs "No_Detect."

[0049] The operator identifying unit 53 appropriately determines whether or not to end the process (steps S70, S72, S74).

[0050] (Operation of the touch processing section) FIG. 13 shows an example of the first image. FIG. 14 shows an example of the second image. As shown in FIGS. 13 and 14, the display region 12 may be provided with (i) a first operation area OP1 in which touches by the first user U1 are valid and touches by the second user U2 are invalid, (ii) a second operation area OP2 in which touches by the first user U1 are invalid and touches by the second user U2 are valid, and (iii) a third operation area OP3 in which touches by both the first user U1 and the second user U2 are valid. In other areas, touches by both the first user U1 and the second user U2 are invalid. An area in which neither touch is valid is referred to as an invalid area.

[0051] 13, when the operator identifying unit 53 supplies the touch processing unit 54 with operator information indicating that the first user U1 is the operator, the touch processing unit 54 switches the first image IMG1 in response to a touch in the first operation area OP1 or the third operation area OP3. Furthermore, the touch in the second operation area OP2 or the invalid area does not switch the first image IMG1.

[0052] 14, when the operator identifying unit 53 supplies the touch processing unit 54 with operator information indicating that the second user U2 is the operator, the touch processing unit 54 switches the second image IMG2 in response to a touch in the second operation area OP2 or the third operation area OP3. Furthermore, the touch in the first operation area OP1 or the invalid area does not switch the second image IMG2.

[0053] When the first image IMG1 and the second image IMG2 are different, the second user U2 may not need to know the operations performed by the first user U1, and the first user U1 may not need to know the operations performed by the second user U2. For example, if the first user U1 is viewing map information and the second user U2 is enjoying content such as videos and music, they may not need to know each other's operations. In such a case, icons or virtual buttons in the first operation area OP1 and the third operation area OP3 in the first image IMG1 may not be displayed in the second image IMG2, and icons or virtual buttons in the second operation area OP2 and the third operation area OP3 in the second image IMG2 may not be displayed in the second image IMG2.

[0054] (Triple view) The display panel 10 of the display device 1 may further be capable of triple viewing, which allows a third user viewing the display panel 10 from a different position from the first user U1 and the second user U2 to see a third image different from the first image IMG1 and the second image IMG2. When triple viewing is possible, the operator identification unit 53 may be able to identify whether the operator is the first user U1, the second user U2, or the third user.

[0055] When the display panel 10 is capable of showing different images to four or more users, the operator identifying unit 53 may be capable of identifying which of the four or more users the operator is.

[0056] [Embodiment 2] (Configuration of control unit) 15 is a functional block diagram illustrating an example of a configuration of a display device according to an aspect of the present disclosure. As shown in FIG. 15, an operator identifying unit 53 according to the second embodiment of the present disclosure sends operator information indicating an operator to a touch accepting unit 52.

[0057] When the operator identifying unit 53 identifies the operator as the first user U1, the touch accepting unit associates the touch information with a first detection flag based on the operator information. On the other hand, when the operator identifying unit 53 identifies the operator as the second user U2, the touch accepting unit 52 associates the touch information with a second detection flag based on the operator information.

[0058] Then, the touch processing unit 54 performs a first process on the touch information associated with the first detection flag, performs a second process on the touch information associated with the second detection flag, and ignores the touch information that is not associated with either the first detection flag or the second detection flag.

[0059] The above configuration can reduce erroneous processing. As shown in FIG. 8, in the method of supplying operator information to the touch processing unit 54, an unexpected time lag may occur between touch information supplied to the touch processing unit 54 at a certain time and proximity information that serves as the basis for the operator information supplied to the touch processing unit 54 at that time. Such a time lag may cause erroneous processing, such as the touch processing unit 54 executing the first process, when, for example, a second user U2 touches the touch panel immediately after a first user U1 approaches. On the other hand, as shown in FIG. 9, in the method of supplying operator information to the touch receiving unit, the first and second detection flags are linked to the touch information. This reduces the possibility of an unexpected time lag occurring between the touch information and the proximity information that serves as the basis for the detection flags. Therefore, the configuration according to the second embodiment can reduce erroneous processing.

[0060] 16 is a schematic diagram illustrating an example of a configuration of a display device according to one embodiment of the present disclosure. As illustrated in FIG. 16, the proximity sensor 30 may include multiple infrared sensors 34. The detection ranges of the multiple infrared sensors 34 are different from one another and extend across the entire display area. For example, the proximity sensor 30 may include: (i) a first infrared sensor 34A that divides a range on a first side of the center of the display area 12 into multiple first zones ZN1 and can detect the proximity of an operator to each of the first zones ZN1; and (ii) a second infrared sensor 34B that divides a range on a second side of the center of the display area 12 into multiple second zones ZN2 and can detect the proximity of an operator to each of the second zones ZN2.

[0061] According to the above configuration, the proximity sensor 30 is a plurality of infrared sensors 34 capable of multi-zone detection. Therefore, compared to the conventional configuration (JP 2009-241707 A) that does not use sensors capable of multi-zone detection, the frame of the display device 1 can be made narrower.

[0062] The area that can be detected by a plurality of infrared sensors 34 working together is larger than the area that can be detected by a single infrared sensor 34. Therefore, the area of ​​the display region 12 can be increased.

[0063] The number of zones that can be divided by multiple infrared sensors 34 working together is greater than the number of zones that can be divided by one infrared sensor 34. Therefore, the display area 12 can be divided into more fine parts, and the identification accuracy by the operator identifying unit 53 can be improved.

[0064] The multiple infrared sensors 34 may be arranged so that they cover each other's blind spots. This arrangement can improve the identification accuracy of the operator identification unit 53. The detection ranges of the multiple infrared sensors 34 may partially overlap each other.

[0065] The configuration according to the third embodiment can be combined with the configurations according to the first and second embodiments described above.

[0066] [Software implementation example] The functions of the control unit 50 of the above-mentioned display device 1 can be realized by a program for causing a computer to function as the control unit 50, and a program for causing a computer to function as each functional block of the control unit 50 (e.g., proximity reception unit 51, touch reception unit 52, operator identification unit 53, touch processing unit 54, proximity sensor control unit 64, display panel control unit 62, and touch sensor control unit 66).

[0067] In this case, the control unit 50 includes a computer having at least one control device (e.g., a processor or a microcomputer) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing each of the functional blocks described in each of the above embodiments.

[0068] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0069] In addition, some or all of the functions of the functional blocks can be realized by logic circuits.
