Distributing processing means based on the liquid crystal indicator shown in Fig. 3 and the touch-control shown in Fig. 4, the embodiment of the present invention is also
Provide the touch-control distribution method of a screen windows display.
Fig. 5 is the flow chart of the touch-control distribution method of a kind of screen windows display of the embodiment of the present invention, and the method should
In the scene of a screen windows display, in this application scenarios, display screen is divided into multiple subwindow, each subwindow
The most corresponding road image input channel, each road image input channel is for connecting from different image input terminals.Such as Fig. 5 institute
Showing, the process step of the method includes:
Step S501: according to user, the touch of display screen is generated touch data, wrap in touch data
Include touch information and touch-control coordinate.
After touch-control processing unit collects the touch of user, generate touch data, wherein at touch number
According to including touch-control coordinate and touch information, wherein this touch-control coordinate refers to the coordinate relative to whole display screen, example
As, in FIG, the resolution of display screen is (M, N), and the resolution of touch-control coordinate is that (m, n), user sends in A window
Touch-control coordinate corresponding to touch is (mM, nN)。
Step S502: determine the subwindow corresponding to touch-control coordinate.
After touch-control processing unit gets touch data, only can determine that the touch-control coordinate in this action data, not
Knowing this subwindow corresponding to touch-control coordinate, in order to accurately process this touch-control coordinate, touch-control processing unit is the most true
This subwindow corresponding to touch data fixed, such as, can determine the son corresponding to touch data according to touch-control coordinate
Window.
Step S503: according to the subwindow corresponding to touch-control coordinate, be response coordinate by touch-control Coordinate Conversion.
After touch-control processing unit determines the subwindow corresponding to the touch received, owing to the image in subwindow is
Image after scaling, and touch-control coordinate remains the coordinate for whole display screen, if directly being sent by touch-control coordinate
Processing to image input terminal, the position that the response position that image input terminal determines is to be operated with touch may not
Unanimously, the failure of touch control operation may thus be caused.
In order to the image in accurate child windows carries out touch control operation, need the touch-control relative to whole display screen
The response coordinate in Coordinate Conversion correspondence subwindow region.
Step S504: touch information and response coordinate are transferred to corresponding image input terminal, for image
Input terminal carries out touch-control process to output to the image of subwindow.
As shown in Figure 6A, the touch-control coordinate that touch-control processing unit arrives at A window reception is (x0, y0), due in A window
The image of display processes through scaling, as shown in Figure 6B, when in computer A, the image information of storage is still displayed in full screen
Image information, therefore touch-control processing unit is by touch-control coordinate (x0, y0) be converted to corresponding with deposited image information in computer A
Response coordinate (Xa, Ya), touch-control processing unit by response coordinate and relevant touch data be sent to computer A and enter
Row processes.
Computer A carries out touch response according to response coordinate (Xa, Ya), and the image after response is input to A window
Showing in Kou, wherein, after computer A response, output is consistent with touch point coordinate to the response point coordinate of the image of A window, is
(x0, y0), it is seen then that utilize embodiment of the present invention method, the coordinate holding of the touch point in each subwindow and response point can be made
Unanimously, and then the touch control operation to each subwindow can be realized.
Fig. 7 is the flow chart of the touch-control distribution method of the another kind one screen windows display of the embodiment of the present invention.The method
Being applied in the scene of a screen windows display, in this application scenarios, display screen is divided into multiple subwindow, every sub-window
The most corresponding road image input channel of mouth, each road image input channel is used for and different image input terminals connects.
As it is shown in fig. 7, the process step of the method includes:
Step S601: touch-control processing unit obtains each subwindow in display screen from the graphics processing unit of display screen
The image input terminal that dividing mode, the coordinate range of each subwindow and each subwindow are the most corresponding.
Optionally, after display screen is divided into multiple subwindow by graphics processing unit, graphics processing unit will display
The image input terminal that dividing mode, the coordinate range of each subwindow and each subwindow of screen is corresponding respectively is sent to touch
Control processing unit.
Or,
Graphics processing unit is after image input channel receives video data, and graphics processing unit is by logical for the input of this image
Each sub-window in image input terminal that subwindow coordinate range corresponding to road, this image input channel are corresponding and display screen
The dividing mode of mouth is sent to touch-control processing unit.
Step S602: touch-control processing unit gathers the touch of user, and generates touch data, wherein at touch-control
Action data includes touch information and touch-control coordinate.
Step S603: touch-control processing unit, according to the coordinate range of each subwindow, determines the coordinate belonging to touch-control coordinate
Scope.
Step S604: touch-control processing unit, according to the coordinate range belonging to touch-control coordinate, determines corresponding to touch-control coordinate
Subwindow.
Step S605: touch-control processing unit, according to the subwindow corresponding to touch-control coordinate, determines that touch-control coordinate is to be amplified
Multiple and the side-play amount of touch-control coordinate.
In the embodiment of the present invention, touch-control processing unit, according to the subwindow corresponding to touch-control coordinate, determines that touch-control coordinate is treated
The multiple amplified and the side-play amount of touch-control coordinate, including: touch-control processing unit is according to the division of each subwindow in display screen
Mode, determines the multiple that touch-control coordinate is to be amplified；Touch-control processing unit is according to the coordinate model of the subwindow corresponding to touch-control coordinate
Enclose, determine the side-play amount of touch-control coordinate.
Step S606: touch-control coordinate, according to touch-control coordinate multiple to be amplified and side-play amount, is turned by touch-control processing unit
It is changed to respond coordinate.
Step S607: touch information and response coordinate are transferred to the input of corresponding image eventually by touch-control processing unit
End.
Below with reference to instantiation, a screen windows display touch-control allocative decision of present example is carried out specifically
Bright.
One, when the liquid crystal indicator shown in Fig. 3 only has image input channel A to connect computer A:
(1) graphics processing unit detects that the resolution of the image from image input channel A input is M1 × N1, display screen
Resolution be M × N, the resolution of touch-control coordinate be (m, n).
1) when liquid crystal indicator is arranged to single window full screen display, if M1 × N1 is equal to M × N, image procossing list
Unit's directly driving display screen carries out image by the resolution of M × N and shows, order notice touch-control processing unit current state of concurrently losing one's life
For when single window full-screen display mode.When M1 × N1 is not equal to M × N, resolution is the image of M1 × N1 by graphics processing unit
The resolution rear drive display screen being scaled M × N shows, order notice touch-control processing unit current state of concurrently losing one's life is for working as
Single window full-screen display mode.The touch-control coordinate data that touch-control module is not sended over by touch-control processing unit is divided again
Join, directly by the touch information received and touch-control coordinate (mM,nN) send to computer A.
