Detailed ways

With the development of computer technology, the split-screen display technology is gradually replacing the traditional projection display technology. When a computer is connected to multiple display devices, the presenter can operate on the main screen to select the content to be displayed on the auxiliary display device by dividing the display area or selecting the file to be displayed. The computer can send the content to be displayed to the auxiliary display device for display, so that the viewer can watch it.

Compared with projection display technology, split-screen display can select an image of a specific area to display on the auxiliary display device. The split-screen display technology is also more convenient for the presenter to edit and modify the displayed content, and has greater flexibility. Especially in the field of education, teachers can display questions on the auxiliary display device and display the answers to the questions on the main display device through the split-screen display technology, which is convenient for teaching.

However, due to the split-screen display technology, the image signal corresponding to the main screen will be collected in real time. When the presenter edits the content to be displayed, the image signal corresponding to the main display area is also sent to other display devices for display. For example, in the process of explaining the example questions, the operation of the teacher's annotation on the question stem will be displayed on the auxiliary display device synchronously, and the students may know the answer to the question in advance after seeing the annotation. In addition, in other fields, if the computer has private or confidential files, the operation of the presenter to open the folder may inadvertently reveal this information.

In order to provide a display scheme in which the display content can be freely controlled by the presenter on the basis of the existing split-screen display technology, the present application provides a split-screen display method, device, terminal and storage medium. The preferred embodiments of the present application will be described in terms of angles.

Referring to FIG. 1, FIG. 1 is a method flowchart of a split-screen display method provided by an embodiment of the present application, including:

S101: In response to an image display instruction, collect a first image of a preset area in a display area of a first display device, and send the first image to a second display device to display the first image in the display area of the second display device to display the first image.

In this embodiment, the presenter may first divide a preset area on the display area of the first display device to display on the second display device. The first display device may be a main display device directly connected to a computer, and the presenter can see the content displayed on the first display device and perform operations; the second display device may be an auxiliary display such as a projector or an electronic blackboard A device used to present the content to be shown to the viewer.

When the computer receives the image display instruction, the first image of the preset area can be collected and sent to the second display device, so that the second display device can display the first image. In this way, the computer can capture an image of a specific area in the display area of the first display device as the first image, and display the second display device when the first image is sent. In this way, the presenter can select any area in the display area of the first display device to be displayed on the second display device.

In some possible implementation manners, the computer may acquire the first image of the preset area by means of video memory copy. Specifically, since the graphics card is a device responsible for processing and outputting video signals by the computer, the content displayed by the first display device is all converted through the graphics card. The computer can acquire the image of the display area of the first display device at the current moment by reading the data in the memory of the graphics card. Next, the computer may obtain an image corresponding to the relative position from the image of the display area of the first display device as the first image according to the relative position of the preset area in the display area of the first display device. In this way, the image displayed in real time in the display area of the first display device can be acquired by means of video memory and copy, so as to realize the synchronous display of the first display device and the second display device.

S102: In response to the maintaining display instruction, copy the first image to obtain a second image, and periodically send the second image to the second display device to display the second image in the display area of the second display device the second image until the execution of the maintaining display instruction is stopped.

When the computer receives the maintaining display instruction, the computer can copy the first image at the current moment as the second image, and stop capturing the first image. The second image is then periodically sent to the second display device for displaying the second image in the display area of the second display device until the maintain display instruction ceases to execute. Specifically, when receiving the maintaining display instruction, the computer can read the first image from the display memory as the second image and store it in the memory, and then send the second image to the second display device according to the refresh rate calculation of the second display device. The time interval of the images, and finally the second image is sent to the second display device according to the time interval. In this way, before the execution of the maintaining display instruction is stopped, the computer can continue to send the second image to the second display device, thereby ensuring that the second display device always displays the second image. Of course, in some other implementation manners, the computer may determine the sending period of the second image in other manners. For example, the computer may send the second image to the second display device at regular intervals. The second display device may store the second image after receiving the second image sent by the computer, and continue to display the second image before the next time interval until the execution of the maintaining display instruction stops.

This embodiment provides a split-screen display method. When performing split-screen display, the display content can be switched according to a received display instruction. When an image display instruction is received, a first image of a preset area may be captured in the display area of the first display device, and the first image may be sent to the second display device for display on the second display device The first image is displayed in the display area; when receiving an instruction to maintain display, the first image can be copied to obtain a second image, and the second image can be periodically sent to the second display device to display the second image in the second display device. The second image is displayed in the display area of the second display device until the execution of the maintaining display instruction is stopped. In this way, the computer can send real-time images or pre-collected images to the second display device in response to different instructions sent by the presenter, and switch between two display states of real-time display and maintenance display. When the presenter needs real-time screen sharing, an image display instruction can be sent. At this time, the content displayed by the second display device and the first display device is synchronized, and the viewer can see the first image displayed on the first display device. When the presenter does not want the viewer to see the image on the first display area, the display maintenance instruction can be sent. At this time, the synchronization between the first display device and the second display device is cut off, and the viewer can only see the receiving instruction. The second image before, does not see what the presenter is doing on the computer after receiving the instruction. In this way, the presenter can freely choose the displayed content, which is suitable for more application scenarios.

In some possible implementations, the presenter may also control the second display device to display other pre-stored pictures through a fixed display instruction. Specifically, when the computer receives the fixed display instruction, it can obtain a pre-stored screen saver picture or other picture as a third image, and periodically send the third image to the second display device to display the second image on the second display device. The third image is displayed in the display area of the device until the execution of the fixed display instruction is stopped. In this way, in response to the fixed display instruction, when the presenter operates, the second display device can be controlled to display a preset screen saver picture, so as to prevent the viewer from seeing the operation performed by the presenter.

In some possible implementations, the presenter may need to update the second image displayed by the second display device. At this time, the presenter can send an update display instruction to the computer. In response to the update display instruction, the computer collects an image of a preset area in the display area of the first display device at the current moment as a new first image, and copies the first image to obtain a new second image. The new second image is then periodically sent to the display area of the second display device for continuous display. In this way, in response to the update display instruction, when the presenter needs to update the second image displayed in the display area of the second display device, the image at the current moment in the preset area can be collected and used as a new second image to complete the second image. Displays an update of what the device displays.

In some possible implementations, the computer may be connected to more than two display devices, each of which may be used to display different content. At this time, the computer may first set up multiple preset collection zones on the first display device according to the instructions of the presenter, and then configure the corresponding relationship between the multiple preset collection zones and the multiple second sub-display devices according to the settings of the presenter. During display, the computer may acquire a plurality of first images of a plurality of preset acquisition regions from the display area of the first display device. And according to the corresponding relationship between the preset acquisition sub-area and the second sub-display device, the plurality of first images are sent to the second sub-display device corresponding to the preset acquisition sub-area where the first images are located. In this way, by recording the corresponding relationship between the preset acquisition partition and the second sub-display device, the first image collected can be sent to the sub-display device corresponding to the preset acquisition partition for display, so as to realize the common display of multiple display devices. It can be used in application scenarios such as splicing multiple screens into a large screen.

In order to facilitate the understanding of the technical solutions of the present application, the split-screen display method provided by the present application will be introduced next in combination with specific teaching scenarios.

Referring to the schematic diagram of the application scenario of the split-screen display method shown in FIG. 2, the scenario includes a classroom 201, a plurality of desks and students 202, a desk 203 equipped with a first display device, and a blackboard 205 equipped with a second display device . The first display device is connected to the computer device, and is used for displaying the courseware for teaching on its display area 205 . The courseware for teaching includes answer part A and test question part B. When a teacher is teaching, a preset area 206 may be set in the display area 205 of the first display device 203 first. When playing the courseware, the computer can capture the first image of the preset area 206 and send it to the second display device 204. In this way, the second display device 204 can display the content in the preset area 206, and the students can see the test questions. B, cannot see part A of the answer.

In the process of students answering the test questions, the teacher may mark part B of the test question, but these marks are seen by the students and may let the students know the answer in advance. In this case, the teacher can send a command to maintain the display to the computer. At this time, the computer responds to the maintenance display instruction, copies the first image at the current moment to obtain the second image, and sends the second image according to the refresh rate of the second display device 204, thereby controlling the second display device 204 to display the pre-marked test question part B. In this way, when the teacher operates the content to be displayed, the student can maintain the display instruction so that the students cannot see their own operation, and can only see the content to be displayed before the operation.
