In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
A touch forwarding device is applied to a touch display device with a touch screen, wherein the touch display device is configured to be connected with at least two signal sources and simultaneously display images of the at least two signal sources. Here, it should be noted that the at least two signal sources may include an external device connected to the touch display device, such as a notebook computer, a tablet computer, and the like; a PC built in the touch display device may also be included. In a specific embodiment, the touch display device is configured to connect three signal sources, wherein the three signal sources include a PC built in the touch display device and two external device signal sources. In another alternative embodiment, the touch display device is configured to connect two signal sources, both of which are external device signal sources.
As shown in fig. 1, the touch forwarding device includes a forwarding control module 1 and a forwarding interface module 2 connected to the forwarding control module 1, where the forwarding control module 1 is configured to obtain touch data from a touch screen 3. The forwarding control module 1 is connected with the touch screen 3 of the touch display device, and may be directly connected or indirectly connected. For example, an acquisition circuit is arranged between the forwarding control module 1 and the touch screen 3, and the acquisition circuit acquires touch data of the touch screen 3 and transmits the touch data to the forwarding control module; for another example, the forwarding control module 1 is directly connected to the touch screen 3, and the forwarding control module 1 directly obtains the touch data of the touch screen 3.
After the touch data of the touch screen 3 is obtained, the forwarding control module 1 is further configured to calculate, according to the touch data and the display area information of each signal source displayed on the touch display device, a touch logic coordinate value of an original touch coordinate value of the touch data relative to each display area, and send the touch data including the touch logic coordinate value to the forwarding interface module 2. The touch data includes original coordinates of the position where the user uses a finger or uses a stylus to click or continuously touch the display screen 3, the display area of the signal source is usually square, the display area information of the signal source refers to coordinate values of four vertex angles of the square relative to the display screen, and the touch logic coordinate values refer to coordinate values of the original coordinates relative to the display area information of the signal source. In a specific embodiment, the lower left corner of the display screen 3 is taken as the origin of coordinates, the entire display screen is divided into 8 × 8 areas, the original coordinates of the relative display screen clicked by the user on the touch screen are (2,3), the coordinate values of the relative display screen at the four corners of the display area of one signal source are (1,1), (5,1), (1,6) and (5,6), the lower left corner of the display area is taken as the origin of coordinates of the display area, and after calculation, the coordinate value of the touched position relative to the display area is (2,2), that is, the touch logic coordinate value is (2, 2). Here, it should be noted that the conversion method of the touch logic coordinate values is not limited to the above simple conversion process, and the conversion of the touch logic coordinate values may be performed by how many calculation methods such as an average value, a variance, an addition, a subtraction, a multiplication, and a division are used in various internal logic control methods.
The forwarding interface module 2 of the touch forwarding device is configured to forward the touch data to the corresponding signal source according to the touch logic coordinate value of the touch data, so that the corresponding signal source executes a corresponding action based on the received touch data. The forwarding interface module 2 includes a plurality of forwarding interface circuit units 21, each forwarding interface circuit unit 21 is used for connecting to a signal source, and the forwarding control module 1 sends the touch data to all forwarding interface circuit units 21 in a broadcast manner. Here, it should be noted that each forwarding interface circuit unit 21 is connected to a signal source, which is a signal source corresponding to the forwarding interface circuit unit 21. In a specific embodiment, an external device is connected to the touch display device through a forwarding interface circuit unit 21, and the forwarding interface circuit unit 21 only transmits the received touch data related to the external device. When the forwarding control module 1 sends the touch data to each forwarding interface circuit unit 21 in a broadcast manner, each forwarding interface circuit unit 21 only receives the touch data of the signal source connected to itself, and ignores the rest of the touch data.
Further, each forwarding interface circuit unit 21 includes a determining submodule 211, configured to determine whether touch data received by the forwarding interface circuit unit 21 includes dedicated touch data of the forwarding interface circuit unit 21, where the forwarding interface circuit unit 21 is configured to send the dedicated touch data to a corresponding signal source according to a determination result, where the dedicated touch data is touch data of a signal source connected to the forwarding interface circuit unit 21. The touch data sent by the forwarding control module 1 includes a display area identification code, and each forwarding interface circuit unit 21 is configured to select and send its own dedicated touch data according to the display area identification code. For example, when two external devices connected to a touch display device are connected to each other via two forwarding interface circuit units 21, the two external devices are connected to the touch display device via two forwarding interface circuit units 21, the two signal sources have corresponding first and second display areas on a display screen, the first display area and the first forwarding interface circuit unit 21 connected to the external device corresponding to the first display area both have a display area identification code 1, the second display area and the second forwarding interface circuit unit connected to the external device corresponding to the second display area both have a display area identification code 2, the touch data sent by the forwarding control module 1 in a broadcast form includes the display area identification code, and the first forwarding interface circuit unit receives information sent by the forwarding control module, only the touch data with the display area identification code 1 is received, i.e. the touch data with the display area identification code 1 is the dedicated touch data of the first forwarding interface circuit unit. When receiving the information sent by the forwarding control module 1, the second forwarding interface circuit unit only receives the touch data containing the display area identification code 2, that is, the touch data containing the display area identification code 2 is the exclusive touch data of the first forwarding interface circuit unit. By setting the judgment sub-module 211, it can be ensured that the touch data received by the forwarding interface circuit unit 21 is definitely the data related and useful to the signal source connected to itself, and the control accuracy is improved. The touch display equipment of different models is provided with different numbers of forwarding interface circuit units, and the touch data transmission in the broadcast mode is not limited by the number of forwarding interface circuit units, so that the touch forwarding device can be applied to touch display equipment of various models, and the flexibility and the universality of the touch forwarding device are enhanced. Of course, it can be understood that when the forwarding control module 1 sends the touch data, a point-to-point sending manner may also be adopted, in a specific embodiment, the touch information sent by the forwarding control module 1 to the forwarding interface circuit unit 21 includes the touch data having the display area identification code 1 and also includes the touch data having the display area identification code 2, so when the touch data is sent in a point-to-point manner, when the forwarding control module 1 sends the touch data to the first forwarding interface circuit unit, the touch data only includes the touch data having the display area identification code 1; when the forwarding control module 1 sends the touch data to the second forwarding interface circuit unit, the touch data only includes the touch data with the display area identification code 2.
Further, the touch forwarding device further includes a display control module 4, the display control module 4 is connected to the forwarding control module 1, the display control module 4 is configured to adjust a position and/or a size of a display area of any signal source displayed on the touch display device, and the display control module 4 is further configured to provide display area information of each signal source displayed on the touch display device to the forwarding control module 1. When the position or the size of the display area of the signal source changes, the display area information of the display area of the signal source, which is acquired by the forwarding control module 1, changes, and then the touched position changes relative to the touch data of the signal source. Of course, it can be understood that, on some types of touch display devices, the position and size of the display area of the signal source cannot be changed, and at this time, the position of the display area that does not change relative to the display screen may be stored in the forwarding control module 1 in advance, and when it is needed, the forwarding control module may read the position.
The application also provides a touch display device, which comprises a touch screen 3 and the touch forwarding device, wherein the forwarding control module 1 of the touch forwarding device is connected with the touch circuit 6 to acquire touch data from the touch screen 3.
Preferably, the touch display device is a touch all-in-one machine, an electronic blackboard, an electronic whiteboard, a multimedia large screen, a touch panel television, an intelligent interactive panel or an interactive display screen, so as to bring more diversified use feelings to users, improve the use and visual experience of the users, and meet the requirements of the users on displaying pictures of multiple signal sources by the touch display device.
The application also provides a touch display device, which is used for carrying out image display and touch operation on a signal source connected with the touch display device, and comprises a touch screen 3 and a display screen 5 which are correspondingly arranged, wherein the touch screen 3 and the display screen 5 are correspondingly arranged on the whole display area of the display screen 5 and are both provided with the touch screen 3; it is also understood that the touch panel 3 is provided at any position where the display panel 5 can display. Of course, it is understood that the touch screen 3 may occupy only a portion of the area of the display screen 5.
As shown in fig. 2, the touch display device in the present application includes:
the touch circuit 6 is connected with the touch screen 3 and used for acquiring an original touch coordinate value of the touched position of the touch screen 3 relative to the display screen 5;
the forwarding control module 1 comprises a control submodule 11, the control submodule 11 is connected with the touch circuit 6, the control submodule 11 is used for receiving an original touch coordinate value and obtaining display area information of a display area of each signal source relative to the display screen 5, and the control submodule 11 is also used for calculating a touch logic coordinate value of a touched position relative to the display area of each signal source according to the display area information and the original touch coordinate value;
the forwarding interface circuit units 21 are configured to be connected to a signal source, each forwarding interface circuit unit 21 is connected to the forwarding control module 1, and the forwarding interface circuit unit 21 is configured to extract dedicated touch data corresponding to a display area of the signal source connected to the forwarding interface circuit unit 21 according to the touch logic coordinate value and transmit the dedicated touch data to the signal source connected to the forwarding interface circuit unit, so that the corresponding signal source executes a corresponding action based on the received touch data.
After obtaining the original touch coordinate value and the display area information of the display area of the signal source, the forwarding control module 1 calculates the touch logical coordinate value of the touched position relative to the display area of each signal source, which is the same as the method introduced in the touch forwarding device and is not described herein again.
The method for obtaining the display area information of the display area of the signal source by the forwarding control module 1 includes the following two methods:
one is that the position and size of the display area of the signal source cannot be changed;
alternatively, the location and size of the display area of the signal source may be varied.
The above two methods for obtaining the display area information of the display area of the signal source are described in detail.
In a specific embodiment, as shown in fig. 2, the forwarding control module 1 further includes a storage sub-module 12 connected to the control sub-module 11, and a plurality of preset display areas are divided on the display screen, and the plurality of preset display areas and the plurality of forwarding interface circuit units 21 are arranged in a one-to-one correspondence manner. The storage submodule 12 is configured to store position information of each preset display area relative to the display screen. The control sub-module 11 is used for reading the position information in the storage sub-module 12 as the display area information. For example, the display screen is divided into a first preset display area and a second preset display area, the first preset display area and the second preset display area may respectively occupy 50% of the display screen, the first preset display area corresponds to the first forwarding interface circuit unit, and the first preset display area can only be used for displaying a picture of a signal source connected to the first forwarding interface circuit unit. The second preset display area corresponds to the second forwarding interface circuit unit, and the second preset display area can only be used for displaying the picture of the signal source connected with the second forwarding interface circuit unit. The control sub-module 11 stores position information, such as coordinate values, of each vertex angle of the first preset display area and the second preset display area relative to the position of the display screen 5. When the control submodule 11 needs to use the position information of the first preset area and the second preset area, the control submodule 11 may directly read the position information in the storage submodule 12 as the display area information.
In another specific embodiment, as shown in fig. 3, the touch display device further includes a display control module 4, and the display control module 4 is connected to the display screen 5 and the control sub-module 11 respectively. The display control module 4 is configured to obtain position information of a display area of the signal source relative to the display screen 5, and transmit the position information as display area information to the control sub-module 11. In this embodiment, the signal source and the display area are in one-to-one correspondence with the forwarding interface circuit unit 21, but the position and/or size of the display area may be adjusted, and when the position or size of the display area of the signal source changes, the display area information of the display area of the signal source acquired by the forwarding control module 1 changes, and then the touched position changes with respect to the touch data of the signal source. Therefore, the display control module 4 needs to constantly acquire the position and size of the display area displayed on the display screen 5, and once the position or size of the display area is changed, the changed display area information of the display area can be timely transmitted to the forwarding control module, so that the forwarding control module 1 can provide accurate touch data for the signal source.
Furthermore, as shown in fig. 3, the forwarding control module 1 further includes a lighting judgment sub-module 13 connected to the control sub-module 11, where the lighting judgment sub-module 13 is configured to judge whether the display areas of the plurality of signal sources have overlapping portions, and if there is an overlapping portion, determine the display area of the signal source currently in a lighting state as an operation interface, and when the touched position is located at the overlapping portion, the control sub-module 11 is configured to determine a touch logic coordinate value of the touched position relative to the operation interface. The display area on the display screen 5 has not only X and Y coordinates on the same plane with respect to the display screen but also a Z coordinate perpendicular to the XY plane. When the display areas of the plurality of signal sources have overlapping portions, it is necessary to determine Z coordinate values of the display areas of the plurality of signal sources, and the display area where the Z coordinate value of the display area is closer to the touch screen 3 is the display area of the signal source in the lit state, that is, the current operation interface. At this time, when the touch position falls on the overlapping portion of the display areas of the plurality of signal sources, the touch position is determined as a position relative to the operation interface, that is, the touch operation is applied to the operation interface, regardless of other display areas overlapping with the portion.
Further, the forwarding control module 1 further includes an output judgment submodule 14, and the output judgment submodule 14 is connected to the control submodule 11 and the plurality of forwarding interface circuit units 21, respectively. The output determining submodule 14 is configured to extract information meeting a predetermined condition from the touch logic coordinate values and output the information to the forwarding interface circuit unit 21, where the predetermined condition is that the touched position falls in the display area of the signal source. In the touch logic coordinate values calculated by the control sub-module 11, there may be a case that the original touch coordinate values do not fall into the display area of the signal source, in this case, the part of the touch logic coordinate values is meaningless for the signal source, and the control sub-module 11 may ignore the touch operation that does not fall into the display area of the signal source, or may display the part of the touch operation through the display screen. However, since the part of touch operation is meaningless for the signal source, the control sub-module 11 ignores the part of touch operation when transmitting the touch logic coordinate values outwards in a broadcast manner, and only transmits the touch logic coordinate values meeting the predetermined condition, that is, only transmits the touch logic coordinate values of which the touched position falls into the display area of the signal source, so as to ensure the control reliability and the accuracy of the transmission content, and avoid the occurrence of misoperation.
In order to further improve the control accuracy, the touch logic coordinate values sent by the output judgment sub-module 14 in the present application include a display area identification code, and each forwarding interface circuit unit 21 is configured to extract and send own dedicated touch data according to the display area identification code.

Because the forwarding control module 1 outputs the touch logic coordinate values to the forwarding interface circuit unit 21 in a broadcast manner, the touch logic coordinate values related to a plurality of display areas may appear in one broadcast, in order to ensure that the signal source can accurately receive the dedicated touch data related thereto and avoid the situation of disordered transmission of the touch data, the determining sub-module 211 determines whether the touch logic coordinate values received by the forwarding interface circuit unit 21 contain the dedicated touch data of the forwarding interface circuit unit 21, and the forwarding interface circuit unit 21 is configured to send the dedicated touch data to the corresponding signal source according to the determination result.
