The embodiment of the present disclosure provides a touch display device, which may have a composition and a structure as shown in fig. 1, and may include: a first display unit 101, a second display unit 102, a touch unit 104, and a processing unit 103 connected to the first display unit, the second display unit, and the touch unit.
In an embodiment of the present disclosure, the touch unit detects a touch operation of a user, generates a touch signal, and sends the generated touch signal to the processing unit.
The processing unit determines a target display unit corresponding to the touch operation from the first display unit and the second display unit according to the touch signal, and sends the touch signal to the target display unit corresponding to the touch operation.
After the first display unit or the second display unit receives the touch signal, corresponding operation is executed according to the touch signal, and an operation result is displayed.
In the embodiment of the present disclosure, the first display unit and the second display unit may be electronic whiteboards, and in this case, the touch display device described in the present disclosure may be referred to as a multi-screen interactive electronic whiteboard or a multi-screen interactive tablet. The multi-screen interactive electronic whiteboard is different from the traditional electronic whiteboard, can realize multiple functions such as multimedia display, touch operation and the like, and can support multiple screens, so that the multi-screen interactive electronic whiteboard can be widely applied to intelligent multimedia teaching or multimedia conferences.
In the embodiment of the present disclosure, the processing unit 103 may divide the total display area corresponding to the touch display device into a first display area and a second display area in advance; wherein the first display area corresponds to the first display unit 101; the second display area corresponds to the second display unit 102.
At this time, the touch signal may include: and the user performs touch control operation on the coordinates in the total display area. The processing unit 103 determines a target display area to which coordinates in the touch signal belong, and uses a display unit corresponding to the target display area as a target display unit; wherein the target display area is one of the first display area and the second display area.
In the embodiment of the present disclosure, the first display unit 101 and the second display unit 102 may be disposed in parallel and multiplexed with one touch unit 104. That is, the two display units share one touch unit. At this time, the touch unit 104 may include: a housing and sensor transmitting and receiving sensing elements mounted on the housing. Specifically, the outer frame may be enclosed on the peripheral edge of the geometric figure obtained by splicing the first display unit 101 and the second display unit 102 placed side by side.
Fig. 2 shows a positional relationship between the touch unit 104 and the first and second display units 101 and 102 according to some embodiments of the present disclosure. As shown in fig. 2, the first display unit 101 and the second display unit 102 that are juxtaposed are spliced together to form a rectangle, so that the outer frame of the touch unit 104 is also a rectangle and surrounds the peripheral edge of the rectangle formed by the first display unit 101 and the second display unit 102 that are juxtaposed. The rectangular coverage area can be regarded as the total display area corresponding to the touch display device. At this time, in the embodiment of the present specification, the above-described total display area may be divided into two display areas: a display area a and a display area B (as shown by a broken line in fig. 2), wherein the first display unit 101 corresponds to the display area a; the second display unit 102 corresponds to the display area B. The above-described division of the display area is related to the size of the screen of the display unit and the arrangement manner between the display units. That is, the processing unit 103 may divide the total display area into the first display area and the second display area in advance according to the sizes of the display screens of the two display units and the stitching manner. In general, the divided display areas are generally substantially equivalent to the size and shape of the screen of the display unit, so that a one-to-one correspondence between the display areas and the display units is achieved.
In an embodiment of the present disclosure, the sensor transmitting element and the receiving sensing element mounted on the outer frame may detect a touch operation of a user in an area surrounded by the outer frame and generate a touch signal.
Furthermore, in some embodiments of the present description, the sensor emitting element may be an infrared emitting element; the receiving sensing element may be an infrared sensing element. The infrared emitting element and the infrared sensing element may be plural, and together form an infrared sensing network in the area surrounded by the outer frame, that is, in the total display area, so that a touch operation of a user in the area may be detected.
In this way, when the user performs a touch operation in the total display area corresponding to the touch display device, the touch unit 104 may detect the touch operation of the user and determine the position information, that is, the coordinates, of the touch operation in the total display area. Then, the touch unit 104 generates a touch signal including coordinates of the touch operation in the total display area. Next, the touch unit 104 feeds back a touch signal to the processing unit 103, and the processing unit 103 determines a target display area to which coordinates of the touch operation in the total display area belong, and uses a display unit corresponding to the target display area as the target display unit. Wherein the target display area is one of the first display area and the second display area.
In other embodiments of the present disclosure, the processing module 103 may further configure a correspondence between the coordinates in the total display area and the coordinates in the first display area and a correspondence between the coordinates in the total display area and the coordinates in the second display area in advance. In this way, after receiving the touch signal, the processing module 103 may further determine the coordinates of the touch operation in the target display area according to the correspondence relationship and the coordinates of the touch operation in the total display area, and replace the coordinates in the touch signal with the coordinates in the target display area.
After receiving the touch signal, the first display unit 101 or the second display unit 102 may perform a corresponding operation according to the coordinates in the touch signal and the current operation mode thereof, and display an operation result in the target display area.
In the embodiment of the present specification, the operation mode may be a touch mode or a drawing mode, or the like. The touch mode generally means that the first display unit 101 or the second display unit 102 normally displays a graphical user interface, and a user may operate the graphical user interface or an object such as an icon displayed on the graphical user interface in a plurality of touch manners, for example, a single click, a double click, a long press, a drag, or a slide manner. The drawing mode generally means that the first display unit 101 or the second display unit currently displays a whiteboard or a background board, and the user can write or draw on the whiteboard in a touch manner, so that the first display unit 101 or the second display unit further displays the content written or drawn by the user on the whiteboard or the background board.
In the embodiment of the present disclosure, the operation mode of the first display unit 101 or the second display unit may be switched by a touch operation of a user. For example, in some embodiments of the present application, control keys for various operation modes of one display device may be displayed at specified positions in the above-mentioned overall display area, or the control keys for various operation modes of one display device may be triggered by a specified operation, at which time the user may select the current operation mode for that display device by clicking these keys. At this time, the interaction process for switching the operation mode is the same as the interaction process of the normal touch operation, and will not be described herein.
In the embodiment of the present disclosure, each display unit may generally display only in its corresponding display area.
In the embodiment of the present specification, the processing unit 103 may be connected to the first display unit 101 or the second display unit 102 through one of a serial interface (abbreviated as serial port) or a USB interface, or a combination thereof. For example, the processing units 103 may be all connected to all display units through serial ports or all USB ports; it is also possible to use a serial connection for one display unit and a USB connection for the other display unit. For example, the first display unit 101 is connected to the processing unit 103 through a USB interface, and the second display unit 102 is connected to the processing unit 103 through a serial interface.
In some embodiments of the present disclosure, the first display unit 101 and the second display unit 102 may use a single operating system, for example, an OPS board card supporting a Windows system or a An Zhuoban card supporting an android system.
In other embodiments of the present disclosure, the first display unit 101 and the second display unit 102 may also use dual operating systems, for example, an OPS board card supporting a Windows system and a An Zhuoban card supporting an android system.
It will be appreciated that the display device 102 described above should include a display screen in addition to the An Zhuoban card and/or OPS board card described above.
In particular, in some embodiments of the present disclosure, the first display unit 101 may generally employ a dual operating system, and the second display unit 102 may generally employ a single operating system. Therefore, the requirements of users can be met, and the cost of the touch display device can be saved.
In this case, the first display unit may include: the first display board card, the second display board card, the change-over switch connecting the first display board card and the second display board card, and the display screen connecting the first display board card and the second display board card, which are connected to the processing unit 103. The first display board corresponds to the first display system; the second display board corresponds to the second display system; and when the current operation system of the first display unit is the second display system, the switch receives the touch signal from the first display board card and outputs the touch signal to the second display board card.
At this time, the second display unit may include: a display board card connected to the processing unit 103 and a display screen connected to the display board card.
In the embodiment of the present disclosure, the first board card may be a An Zhuoban card; the first operating system may be an android system; the second board card may be an OPS board card; the second operating system may be a Windows operating system. Of course, the reverse is also possible.
When the first display unit 101 adopts the dual operating systems, in the embodiment of the present disclosure, the change-over switch in the first display unit 101 determines the working state thereof according to the current operating system of the first display unit 101, for example, when the current operating system is the operating system corresponding to the first board card, the switch does not work; and when the current operating system is the operating system corresponding to the second board card, the touch signal is received from the first board card and is output to the second board card.
For example, when the first display unit 101 uses the android system as its own first operating system, the An Zhuoban card will be connected to the processing unit 103. At this time, the change-over switch would be mounted on the An Zhuoban card and connect the output to the OPS board. When the current operating system of the first display unit 101 is an android system, the change-over switch does not work; when the current operating system of the first display unit 101 is a Windows system, the switch receives the touch signal from the An Zhuoban card and outputs the touch signal to the OPS board.
Conversely, when the first display unit 101 uses the Windows system as its own first operating system, the OPS board will be connected to the processing unit 103. At this time, the change-over switch would be mounted on the OPS board and connect the output to the An Zhuoban card. When the current operating system of the first display unit 101 is a Windows system, the switch does not work; when the current operating system of the first display unit 101 is android system, the switch receives the touch signal from the OPS board and outputs the touch signal to the An Zhuoban card.
In an embodiment of the present disclosure, the switch may be a USB switch (USB switch).
It can be seen that, in the embodiment of the present disclosure, a multi-screen touch display device may be implemented by dividing a total display area formed by splicing two display units into at least two display areas, and associating the divided two display areas with the two display units. In this way, when the user performs the touch operation, the processing unit 103 may determine, according to the position of the touch operation of the user, the target display area to which the operation of the user belongs, and further determine the display unit corresponding to the touch operation of the user, so that the touch signal generated by the touch operation of the user may be sent to the corresponding display unit, and the corresponding display unit performs the corresponding operation and gives the corresponding response, so as to implement the multi-screen interactive touch operation, which may perform the independent operation on the multiple screens, or perform the simultaneous operation on the multiple screens, and may even provide a hardware base for the association operation between the multiple screens. Moreover, as the plurality of display units can share the same set of touch control unit and processing unit, the realization cost of the touch control display device is lower. Furthermore, the touch display device can also support various systems, and is more flexible in configuration, so that the application requirements of users are met to a greater extent.
It should be noted that the method is not only applicable to a dual-screen touch display device, but also can be generally applied to a multi-screen touch display device. For example, one or more display units may be further added in addition to the first display unit 101 and the second display unit 102 described above. The plurality of display units together multiplex a set of touch units 104 and processing units 103. The processing unit 103 may determine the total display area according to the sizes and the arrangement modes of the display screens of the display units, and divide the total display area, so that the divided display areas are in one-to-one correspondence with the display units. After receiving the touch signal, the processing unit 103 may determine a display unit corresponding to the touch operation of the user according to the coordinate information in the touch signal, so as to send the touch signal to the corresponding display unit for performing the touch operation processing.
The technical solutions of the embodiments of the present specification will be described in detail below with reference to the accompanying drawings and specific examples.
Fig. 3 is a schematic structural diagram of a touch display device according to an embodiment of the disclosure. As shown in fig. 3, the touch display device may include: the touch control unit 301, the processing unit 302, a main display unit 303 connected to the processing unit 302 through a USB interface, and a sub display unit 304 connected to the processing unit 302 through a serial interface.
The main display unit 303 and the auxiliary display unit 304 are both single operating systems, and may include an OPS board card supporting a Windows system or a An Zhuoban card supporting an android system, for example. For cost reasons, an Zhuoban cards may be used for both the main display unit 303 and the sub display unit 304, as shown in fig. 3.
In the example shown in fig. 3, the main display unit 303 and the auxiliary display unit 304 may be spliced together side by side, and the outer frame of the touch unit 301 may cover the outer sides of the main display unit 303 and the auxiliary display unit 304, and divide the area surrounded by the outer frame of the touch unit 301 into two display areas (as shown by two dashed boxes in the figure) according to the sizes and the splicing modes of the display screens of the main display unit 303 and the auxiliary display unit 304, where the display area a corresponds to the main display unit 303; the display area B corresponds to the sub display unit 304.
Further, the correspondence between the coordinates in the area surrounded by the outer frame of the touch unit 301 and the coordinates in the display areas corresponding to the main display unit 303 and the sub display unit 304 may be established according to the sizes and positions of the display screens of the main display unit 303 and the sub display unit 304.
Specifically, assuming that the range of the X-axis coordinates output by the touch unit 301 is 0 to 255 and the range of the Y-axis coordinates output is 0 to 100, the range of the output coordinates of the total display area occupied by the main display unit 303 may be defined as the X-axis: 0-160, Y axis: 0 to 100; the output coordinate range that defines the total display area occupied by the sub display unit 304 is the X axis: 165-255, Y axis: 0 to 80.
In practical applications, the coordinate range may be determined according to the sizes of the display screens of the main display unit and the auxiliary display unit, for example, the display screens of the main display unit and the auxiliary display unit may be spliced together first, the size of the total display screen is determined, and the total display screen is segmented to determine the range of the X-axis coordinate and the range of the Y-axis coordinate output by the touch unit 201; and then, respectively determining the output coordinate range of the main display unit and the output coordinate range of the auxiliary display unit according to the proportion of the display screens of the main display unit and the auxiliary display unit to the total display screen. It should be noted that the method is not only applicable to a dual-screen touch display device, but also can be generally used for a multi-screen interactive touch display device. Furthermore, based on the above method, a correspondence relationship between the coordinates in the area surrounded by the outer frame of the touch unit 301 and the coordinates in the display areas corresponding to the main display unit and the auxiliary display unit may be established.
Although in the example shown in fig. 3, the processing unit 302 is connected to the main display unit 303 through a USB interface and to the sub display unit 304 through a serial port, in practical applications, the processing unit 302 may be connected to the sub display unit 304 through a USB interface; the main display unit 303 may be connected using a serial port; or other connection interfaces between devices may be used without departing from the scope of this specification.
It can be seen that the present example provides a dual-screen interactive touch display device that may include two independent screens, and that a user may implement separate or simultaneous control of the two independent screens through one infrared touch frame, as if a screen including two pictures were operated. The example also has the characteristics of convenient implementation and low cost.
In addition, the association operation of the main display unit 303 and the sub display unit 304 may be realized by performing a hardware and software association design on the main display unit 303 and the sub display unit 304.
Fig. 4 is a schematic structural diagram of a touch display device according to another embodiment of the disclosure. As shown in fig. 4, the dual-screen interactive touch display device may include: the touch control unit 401, the processing unit 402, a main display unit 403 connected to the processing unit 402 through a USB interface, and a sub display unit 404 connected to the processing unit 402 through a serial interface.
The main display unit 403 supports dual operating systems, including: an Zhuoban card supporting android system and OPS board card supporting Windows system. The An Zhuoban card is connected to the USB interface, assuming that the android operating system is the default operating system. The main display unit 403 will also include a USB switch to connect the An Zhuoban card and OPS card supporting Windows system, which will be installed on An Zhuoban card and connect the output to OPS card, in order to switch touch data between the two systems. When the current operating system is an android system, the change-over switch does not work; when the current operating system is a Windows system, the switch receives touch data from the An Zhuoban card and outputs the touch data to the OPS board.
The secondary display unit 404 supports a single operating system, and may include an OPS board card supporting a Windows system or a An Zhuoban card supporting an android system, for example. For cost reasons, the secondary display unit 404 may use a An Zhuoban card.
In the example shown in fig. 4, the main display unit 403 and the auxiliary display unit 404 may be spliced together side by side, and the outer frame of the touch unit 401 may cover the outer sides of the main display unit 403 and the auxiliary display unit 404, and divide the area surrounded by the outer frame of the touch unit 401 into two display areas (as shown by two dashed boxes in the figure) according to the sizes and the splicing manner of the display screens of the main display unit 403 and the auxiliary display unit 404, where the display area a corresponds to the main display unit 403; the display area B corresponds to the sub display unit 404.
In this example, reference may be made to the example shown in fig. 3 described above for the method of dividing the display regions and the method of mapping the coordinates between the display regions, and the description thereof will not be repeated.
Although in the example shown in fig. 4, the processing unit 402 is connected to the secondary display unit 404 through a serial port, in practical applications, the processing unit 402 may be connected to the secondary display unit 404 through a USB port or may be connected to other devices through a connection interface without departing from the scope of the present disclosure.
Although in the example shown in fig. 4, the main display unit 403 supports a dual operating system and the sub display unit 404 supports a single operating system, in practical applications, the sub display unit 404 may support a dual operating system. At this time, the secondary display unit 404 may also include a switch that connects the own An Zhuoban card and the OPS board card, so as to implement switching between two operating systems supported by the touch signal itself.
It can be seen that the present example provides a dual-screen interactive touch display device, which may include two independent screens, and a user may implement separate or simultaneous control of the two independent screens through one touch unit, as if a screen including two pictures is operated. Moreover, in this example, the main display unit 403 not only supports the android system but also supports the Windows system, which improves the compatibility of the dual-screen interactive touch display device, and can meet various demands of users.
As described above, the processing unit may further configure in advance a correspondence between the coordinates in the total display area and the coordinates in the first display area and a correspondence between the coordinates in the total display area and the coordinates in the second display area. It should be noted that, the above-mentioned correspondence may be a mapping relationship of coordinates, and may generally be a pre-configured mathematical expression representing the mapping relationship of coordinates. According to the mathematical expression, the coordinates of the touch operation of the user in the target display area can be calculated according to the coordinates of the touch operation of the user in the area surrounded by the outer frame of the touch unit. In general, the above-described coordinate mapping relationship may be determined simultaneously when the display area division configuration is performed. For example, when dividing the display area, the output coordinate ranges of the display devices are divided according to the sizes and arrangement positions of the display screens of the display devices, and then the mapping relationship of the coordinates can be directly determined after the division, that is, the mapping relationship from the coordinates in the range surrounded by the infrared touch frame to the coordinates in the display device is established.
The specific operation of the processing unit will be described in detail below with a specific example. It is assumed that a rectangular planar coordinate system is used to represent the area surrounded by the outer frame of the touch unit, that is, the total display area, in the range of 0 to 255X-axis coordinates and in the range of 0 to 100 y-axis coordinates. And dividing the above area into two display areas: the X-axis coordinate range of the display area 1 is 0-160, and the Y-axis coordinate range is 0-100, and the display area corresponds to the first display unit; the X-axis coordinate ranges 161 to 255 and the y-axis coordinate ranges 0 to 100 of the display area 2 correspond to the second display unit. And the mapping relation between the coordinates in the total display area range and the coordinates of the second display unit can be established as X-axis coordinates minus 160, and Y-axis coordinates are unchanged.
In this case, when detecting that the position of the touch operation of the user within the total display area is (50, 50), the processing unit may first determine that the position of the touch operation belongs to the display area 1, that is, corresponds to the first display unit. Then, the processing unit obtains the position of the touch operation of the user in the display area corresponding to the first display unit according to the corresponding relation (e.g., mapping expression) between the coordinates of each position in the total display area (the coordinates of each position in the display area 1) and the coordinates of each position in the display area corresponding to the first display unit, for example, (50, 50), and connects the touch signal to the output port of the first display unit. At this time, the first display unit executes a corresponding operation according to the current operation mode after receiving the touch signal, and outputs a corresponding response.
In another case, when detecting that the position of the touch operation of the user within the total display area is (200,50), the processing unit may first determine that the position of the touch operation belongs to the display area 2, that is, corresponds to the second display unit. Then, the processing unit obtains the position of the touch operation of the user in the display area corresponding to the second display unit according to the corresponding relation (e.g., mapping expression) between the coordinates of each position in the total display area (the coordinates of each position in the display area 2) and the coordinates of each position in the display area corresponding to the second display unit, for example, (40, 50), and connects the touch signal to the output port of the second display unit. At this time, the second display unit executes a corresponding operation according to the current operation mode after receiving the touch signal, and outputs a corresponding response.
Of course, in other embodiments of the present disclosure, the processing unit may also directly send the coordinates (200,50) to the corresponding second display unit, and the second display unit determines, according to its configuration, the corresponding position of the touch operation on its display screen.
It can be seen that, in the embodiment of the present disclosure, the total display area corresponding to the touch display device is divided into at least two display areas, so that the at least two display areas and the at least two display units can be corresponding to implement a multi-screen interactive touch display device. In this way, when the user performs touch operation in the total display area, the processing unit can determine the display area to which the user operation belongs according to the position of the user touch operation, and further determine the output port for outputting the touch signal, so that the touch signal can be sent to the corresponding display unit through the corresponding output port, the corresponding display unit performs corresponding operation and gives corresponding response, so as to realize the touch operation of the multi-screen interactive touch display device, and the touch operation can be performed on the multiple screens independently or simultaneously, and even provide a hardware basis for the association operation between the multiple screens.
Corresponding to the touch display device, the embodiment of the present disclosure also provides a touch display method, which may be implemented by a touch display device.
Fig. 5 is a flowchart of a touch display method according to an embodiment of the present disclosure. As shown in fig. 5, the method may include:
in step 502, after detecting the touch operation of the user, a touch signal is generated.
In an embodiment of the present disclosure, the touch signal may include coordinates of a touch operation of a user in a total display area corresponding to the touch display device.
In step 504, a target display unit corresponding to the touch operation is determined from the first display unit and the second display unit included in the touch display device according to the touch signal.
In step 506, the touch signal is sent to the target display unit corresponding to the touch operation.
And after receiving the touch signal, the target display unit executes corresponding operation according to the touch signal and displays an operation result.
In an embodiment of the present disclosure, the method may further include: dividing a total display area corresponding to the touch display device into a first display area and a second display area; the first display area corresponds to the first display unit; the second display area corresponds to the second display unit; wherein,
The determining, according to the touch signal, the target display unit corresponding to the touch operation from the first display unit and the second display unit included in the touch display device in the step 504 may include: determining a target display area to which the coordinates belong, and taking a display unit corresponding to the target display area as the target display unit; wherein the target display area is one of the first display area and the second display area.
In an embodiment of the present disclosure, the method may further include: and pre-configuring the corresponding relation between the coordinates in the total display area and the coordinates in the first display area and the corresponding relation between the coordinates in the total display area and the coordinates in the second display area.
At this time, before the above step 506, further execution may be performed: and determining the coordinates of the touch operation in the target display area according to the corresponding relation and the coordinates of the touch operation in the total display area, and replacing the coordinates in the touch signal by the coordinates in the target display area.
It can be seen that, in the embodiment of the present disclosure, when the user performs the touch operation in the total display area, the processing unit may determine, according to the position of the touch operation of the user, the display unit corresponding to the operation of the user, and the corresponding display unit performs the corresponding operation and gives a corresponding response to implement the multi-screen interactive touch operation. Specifically, the correspondence may be achieved by dividing the total display area corresponding to the touch display device into two display areas, and the two display areas and the two display units may be in one-to-one correspondence. It can be seen that, by the touch display method of the present specification, not only can the multiple screens of the touch display device be operated independently, but also the multiple screens can be operated simultaneously, and even a hardware and software foundation can be provided for the association operation between the multiple screens.
