[0034] In this embodiment, a method for displaying a screen running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] FIG2 is a flow chart of a method for displaying a screen according to an embodiment of the present disclosure. As shown in FIG2 , the method includes the following steps:

[0036] Step S201: upon receiving a screen update command, the timing controller reduces the original resolution to a preset resolution, wherein the screen update command is a command for displaying a first screen, and the first screen is a screen that needs to be displayed simultaneously with the original screen of the screen;

[0037] Specifically, if the existing screen is displaying a picture, called the original picture, and the timing controller TCON (Timer Control Register, TCON for short) receives a command to update the picture, that is, the timing controller receives a command to display another picture based on the original picture. This picture is called an additional picture in the background technology, and is referred to as the first picture below. In order to prevent the information of the original picture from being blocked by the information of the first picture while displaying the first picture, the above steps first reduce the resolution of the picture, that is, the timing controller reduces the original resolution to a preset resolution, so that the space occupied by the original picture on the screen can be reduced, and the reduced resolution can be further allocated to the additional picture, i.e., the first picture, for display, so that the problem of the first picture covering or blocking the original picture will no longer occur.

[0038] Step S202, the timing controller sends the preset resolution to the graphics card, so that the graphics card outputs a picture with the preset resolution, obtains a second picture, and sends the second picture to the timing controller;

[0039] Specifically, the timing controller only reduces the original resolution to the preset resolution, and the graphics card outputs the picture of the preset resolution. That is, the timing controller sends the preset resolution parameter to the graphics card, so that the graphics card outputs the picture of the preset resolution, that is, the second picture to the timing controller. That is to say, the second picture is the original picture after the resolution is reduced. The content displayed on the second picture is the same as the original picture, but the resolution is reduced.

[0040] In step S203 , the timing controller receives the first picture and the second picture, splices the first picture and the second picture into a picture of the original resolution to obtain a target picture, and sends the target picture to a screen for display.

[0041] Specifically, the timing controller receives the second picture sent by the graphics card, that is, the original picture with reduced resolution, and receives the additional picture that needs to be displayed simultaneously, that is, the first picture. Since the resolution of the second picture is smaller than that of the original picture, the space occupied by the second picture is also reduced. The reduced part is spliced ​​with the first picture to obtain a complete picture with the original resolution. The spliced ​​image with the original resolution includes the first picture (the additional picture in the background technology) and the second picture (the original picture with reduced resolution), achieving the effect of displaying the two pictures simultaneously without blocking or covering each other. Moreover, the first picture and the second picture in the target picture obtained after splicing can both be kept updated, overcoming the shortcomings of the prior art in which part of the original picture's content is covered or blocked and the original picture can no longer be updated.

[0042] Through this embodiment, when the timing controller receives a command to display the first screen, i.e., update the screen, it reduces the original resolution of the screen to a preset resolution, and sends the preset resolution to the graphics card, so that the graphics card outputs a screen with the preset resolution, i.e., the second screen. The timing controller receives the first screen and the second screen, and splices the first screen and the second screen into a screen with the original resolution to obtain a target screen, and sends the target screen to the screen for display. Compared with the method in the prior art where, when two screens are displayed simultaneously, one screen will cover the information of the other screen and the information of the covered screen can no longer be updated, the present disclosure can display the information of two screens at the same time, where the information of one screen will not be covered or blocked, and both screens can be kept updated without affecting each other. Therefore, it can solve the problem in the prior art where, when two screens are displayed simultaneously, the information of one screen is blocked, and achieve the purpose of displaying the information of two screens at the same time.

[0043] In a specific implementation process, the above-mentioned step S201 can be implemented by the following steps: the above-mentioned timing controller reduces the row resolution of the above-mentioned original resolution to obtain the above-mentioned preset resolution; the above-mentioned timing controller reduces the column resolution of the above-mentioned original resolution to obtain the above-mentioned preset resolution; the above-mentioned timing controller reduces the above-mentioned row resolution and the above-mentioned column resolution of the above-mentioned original resolution to obtain the above-mentioned preset resolution. The method reduces the parameter of the original resolution by reducing the row resolution or the column resolution or reducing both the row resolution and the column resolution. In this way, the original resolution can be reduced in various ways, and the reduced resolution can be allocated to the subsequent first picture that needs to be displayed additionally. In this way, the first picture and the subsequent second picture are spliced ​​according to any of the above-mentioned methods, thereby increasing the diversity and flexibility of the picture display.

[0044] In some optional embodiments, if the original resolution is 1920×1280, the row resolution is reduced to obtain a preset resolution, for example, 720×1280; the column resolution is reduced to obtain a preset resolution, for example, 1920×1080; and both the row resolution and the column resolution are reduced to obtain a preset resolution, for example, 720×1080. Of course, in actual application, the preset resolution can be set according to the actual application scenario, that is, this disclosure does not specifically limit the value of the preset resolution.

[0045] In order to splice the first picture and the second picture according to the preset resolution so that the first picture and the second picture can be displayed simultaneously after being spliced, the above-mentioned step S203 of the present disclosure can be implemented by the following steps: when the above-mentioned timing controller reduces the row resolution of the above-mentioned original resolution, the above-mentioned first picture and the above-mentioned second picture are spliced ​​up and down to obtain the above-mentioned target picture; when the above-mentioned timing controller reduces the column resolution of the above-mentioned original resolution, the above-mentioned first picture and the above-mentioned second picture are spliced ​​left and right to obtain the above-mentioned target picture; when the above-mentioned timing controller reduces the above-mentioned row resolution and the above-mentioned column resolution of the above-mentioned original resolution, the above-mentioned first picture and the above-mentioned second picture are embedded and spliced ​​to obtain the above-mentioned target picture. The method splices the received first picture and the second picture according to the above-mentioned resolution reduction method, that is, the preset resolution, so that the part of the resolution reduced by the second picture can be compensated by the first picture according to the preset resolution, and the target picture with the complete original resolution can be spliced. Further, the first picture and the second picture can fill the entire screen picture while making the first picture and the second picture fully displayed without overlapping or blocking each other, so as to more flexibly realize the display of the target picture.

[0046] Specifically, after the second picture is obtained by reducing the resolution by any of the above methods, if the preset resolution is obtained by reducing the row resolution, it can be understood that the number of rows of the second picture is reduced. In this case, the first picture is spliced ​​by compensating for the reduced row resolution, which can be specifically: the first picture is placed above the second picture or the first picture is placed below the second picture, that is, the top and bottom splicing method, for example: the original resolution is 1920×1280, the preset resolution, that is, the resolution of the second picture is 720×1280, then the resolution of the first picture is 1200×1280; if the preset resolution is obtained by reducing the column resolution, it can be understood that the number of columns of the second picture is reduced. When the number of columns is reduced, the first picture is spliced ​​by compensating for the reduced column resolution, which can be specifically: the first picture is placed on the left of the second picture or the first picture is placed on the right of the second picture, that is, the left and right splicing method, for example: the original resolution is 1920×1280, the preset resolution, that is, the resolution of the second picture is 720×1280. If the resolution of the second screen is 1920×1080, then the resolution of the first screen is 1920×200. If the preset resolution is obtained by reducing the row resolution and column resolution, it can be understood that the number of rows and columns of the second screen is reduced. In this case, the first screen needs to make up for the reduced number of rows and columns, which can be called embedded splicing. For example, if the original resolution is 1920×1280 and the preset resolution, i.e., the resolution of the second screen, is 720×1080, then the resolution of the first screen is 1200×200. The first screen can be placed in the lower left corner, lower right corner, upper left corner, or upper right corner of the entire screen, so that the second screen is still displayed as the main screen. Since the second screen is the original screen with a reduced resolution, displaying the second screen as the main screen can more intuitively allow the audience to obtain the information of the main screen. The information of the first screen as an additional screen is not the key information that the user needs to obtain (mainly advertising lights). Therefore, the space occupied can be smaller, providing a better user experience.

[0047] After step S203, the method further includes the following steps: upon receiving a command to exit the display of the first screen, the timing controller sends the original resolution and an interrupt signal to the graphics card, so that the graphics card outputs a screen with a resolution of the original resolution to obtain a third screen, and sends the third screen to the timing controller, wherein the command to exit the display of the first screen is a command indicating exiting the first screen; and the timing controller sends the third screen to the screen for display. When exiting the display of the first screen, the method continues to restore the original resolution and causes the graphics card to output the screen with the original resolution, outputting it to the screen for display. In this way, when exiting the display of the first screen, the first screen is no longer displayed, and the screen with the original resolution, i.e., the third screen, continues to be displayed.

[0048] In a specific implementation, after the first screen is no longer needed for display, indicating that the display of the additional screen is to be exited, the timing controller receives a command indicating the exit of the first screen display, i.e., the first screen display command. The timing controller then sends the initial native resolution to the graphics card, causing the graphics card to no longer output the second screen according to the preset resolution, but instead output the third screen at the native resolution. This third screen is the original screen mentioned above, i.e., the second screen at the native resolution. The graphics card sends the third screen to the timing controller, which then sends the third screen to the screen for display, thereby returning the screen to its original display (the original screen). The graphics card and the timing controller communicate via an EDP (Embedded Display Port, a digital interface used in laptops and tablets) link. If the resolution needs to be changed, the timing controller sends an HPD IRQ (hot plug interrupt request, HPD Interrupt Request, referred to as HPD IRQ) and the preset resolution or the native resolution to the graphics card, causing the graphics card to reconfigure the EDP link according to the preset resolution or the native resolution, causing the graphics card to output the preset resolution or the native resolution to the timing controller.

[0049] In order to promptly update the first and second screens in the target screen, in some embodiments, after step S203, the method further includes the following steps: upon receiving the updated first screen, updating the first screen in the target screen; upon receiving the updated second screen, updating the second screen in the target screen. This method updates the first and second screens upon receiving the updated first and second screens, thereby promptly updating the target screen and allowing both the first and second screens to be updated. This avoids the problem of one screen failing to be updated when the two screens are displayed simultaneously, resulting in the user being unable to obtain updated screen information.

[0050] In some optional embodiments, the current screen displays the target screen, i.e., the first screen and the second screen, and when each screen is dynamic, the screen itself needs to be updated in real time. The above steps can update the first screen in real time when the updated first screen is received, and update the second screen in real time when the updated second screen is received. When the updated first screen and the updated second screen are received at the same time, both the first screen and the second screen are updated to ensure that the user can obtain information about the first screen and the second screen at the same time. As mentioned in the background technology, in the prior art, one screen will be blocked or covered, and the blocked or covered screen cannot be updated in real time. In this way, the user can no longer continue to obtain information about the covered screen, and can only obtain information about the screen above the covered screen, resulting in a poor user experience.

[0051] In some embodiments, step S201 further includes the following steps: upon receiving a screen update command, before the timing controller reduces the original resolution to the preset resolution, the timing controller receives a fourth frame from the graphics card, wherein the fourth frame is the last frame received from the graphics card before the timing controller reduces the original resolution to the preset resolution; and the fourth frame is sent to the screen for display. This method sends the fourth frame, the last frame received at the original resolution, to the screen for display before simultaneously displaying the first and second frames. This avoids the screen from stopping displaying if the target frame, which is the combination of the first and second frames, has not yet been loaded.

[0052] Specifically, the timing controller requires a certain buffer period to reduce the original resolution to the preset resolution and receive the first and second images. Even if it is a very small period of time, the screen cannot stop displaying the image, such as a black screen, etc., which will make the user experience worse. Therefore, when the timing controller receives the above-mentioned update screen command, the last frame of the original resolution sent by the graphics card, that is, the original image, is sent to the screen for display. That is, during this buffer period, the screen displays the image with the original resolution.

[0053] To accurately splice the first and second images, in a specific implementation, while the timing controller receives the first and second images, the timing controller also receives attribute information of the first image sent by the motherboard controller, the attribute information including at least position information and color information of the first image. The method also receives the attribute information of the first image to better splice the first and second images based on the attribute information.

[0054] In some optional embodiments, since the first picture needs to be spliced ​​with the second picture, the first picture needs to have position information. At the same time, the timing controller also needs to synchronously receive color information of the first picture, etc., collectively referred to as attribute information. Based on the above position information, the timing controller can better splice the first picture and the second picture in accordance with the negotiation requirements of the mainboard controller EC.

[0055] In a specific implementation, the second image is the image output by the graphics card after it receives an interrupt signal, interrupts the connection link with the timing controller, and generates a new connection link based on the preset resolution. The interrupt signal is a signal that controls the interruption of the connection link between the timing controller and the graphics card. In this method, the timing controller instructs the graphics card to output an image at the preset resolution by sending an interrupt signal, so that the graphics card outputs the image after the resolution is changed, i.e., the second image, to further enable splicing of the first and second images.

[0056] Specifically, as mentioned above, data is transmitted between the graphics card and the timing controller through the EDP link. When the resolution needs to be changed, the amount of valid data sent down the link will change, including row valid data and column valid data. The timing controller sends the HPD IRQ and the preset resolution or the original resolution to the graphics card (the preset resolution is sent in the above step) to enable the graphics card to reconfigure the EDP link according to the above preset resolution, so that the graphics card outputs the picture of the preset resolution, that is, the second picture to the timing controller.

[0057] In order to enable those skilled in the art to more clearly understand the technical solution of the present disclosure, the implementation process of the screen display method of the present disclosure will be described in detail below with reference to specific embodiments.

[0058] This embodiment relates to a specific method for displaying a screen, as shown in FIG3 to FIG5 , including the following steps:

[0059] FIG3 illustrates a conventional display method in which conventional on-screen display (OSD) information (an additional image, referred to as the first image above) overlays the GPU (graphics card) display content (the original image, referred to as the second image) on the frame sent by the GPU (i.e., the second image).

[0060] Step S1: FIG4 is a specific screen display method of the present disclosure. When receiving a screen update command (such as an update screen command: ANX DPCD), the timing controller TCON stores the last frame of the screen (the fourth screen) received from the graphics card in the SRAM (static random access memory) inside the timing controller, and the timing controller TCON sends the fourth screen to the screen for display.

[0061] Step S2: The timing controller TCON reduces the original resolution, for example, by reducing the number of rows of EDID (Extended display identification data, EDID for short), or reducing the number of columns of EDID, or reducing the number of rows and columns of EDID to obtain a preset resolution, and sends an HPD IRQ (hot plug interrupt signal) to the graphics card GPU, requesting the GPU to change the number of valid rows of the sent frame. The graphics card performs eDP link training according to the EDID information and TCON, and changes the resolution of the eDP link, so that the graphics card sends an image of the preset resolution, i.e., the second image, to the timing controller via the eDP link.

[0062] Step S3: The embedded controller (EC) sends the first image and the first image information (attribute information) to the timing controller (TCON) via the I2C interface. The TCON stitches the first image and the frame sent by the GPU (the second image sent by the graphics card) into an image with the original resolution and sends it to the screen for display.

[0063] Step S4: When the timing controller TCON receives the updated first picture and the updated second picture, it can update the second picture sent by the graphics card or the first picture sent by the motherboard controller respectively;

[0064] Step S5: Figure 5 is a flowchart when the system receives the command to exit the first screen display. The timing controller TCON restores the original resolution EDID, for example, restores the number of lines of the EDID to the number of lines of the original EDID, that is, the physical complete and valid lines of the screen, and sends a hot plug interrupt signal to the graphics card. The graphics card GPU outputs the image of the original resolution, that is, the third image, through the eDP link according to the EDID information and TCON, and sends the third image to the screen Panel for display.

[0065] The embodiment of the present disclosure also provides a timing controller. It should be noted that the timing controller of the embodiment of the present disclosure can be used to execute the display method for the screen provided by the embodiment of the present disclosure. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0066] The following introduces the timing controller provided by the embodiments of the present disclosure.

[0067] FIG6 is a schematic diagram of a timing controller according to an embodiment of the present disclosure. As shown in FIG6 , the timing controller 10 is used to:

[0068] When receiving an update screen command, the timing controller 10 reduces the original resolution to a preset resolution, wherein the update screen command is a command for displaying a first screen, and the first screen is a screen that needs to be displayed simultaneously with the original screen of the screen;

[0069] Specifically, if the existing screen is displaying a picture, called the original picture, and the timing controller TCON (Timer Control Register, TCON for short) receives a command to update the picture, that is, the timing controller receives a command to display another picture based on the original picture. This picture is called an additional picture in the background technology, and is referred to as the first picture below. In order to prevent the information of the original picture from being blocked by the information of the first picture while displaying the first picture, the above steps first reduce the resolution of the picture, that is, the timing controller reduces the original resolution to a preset resolution, so that the space occupied by the original picture on the screen can be reduced, and the reduced resolution can be further allocated to the additional picture, i.e., the first picture, for display, so that the problem of the first picture covering or blocking the original picture will no longer occur.

[0070] The timing controller 10 sends the preset resolution to the graphics card, so that the graphics card outputs a picture with the preset resolution to obtain a second picture, and sends the second picture to the timing controller;

[0071] Specifically, the timing controller only reduces the original resolution to the preset resolution, and the graphics card outputs the picture of the preset resolution. That is, the timing controller sends the preset resolution parameter to the graphics card, so that the graphics card outputs the picture of the preset resolution, that is, the second picture to the timing controller. That is to say, the second picture is the original picture after the resolution is reduced. The content displayed on the second picture is the same as the original picture, but the resolution is reduced.

[0072] The timing controller 10 receives the first picture and the second picture, splices the first picture and the second picture into a picture of the original resolution to obtain a target picture, and sends the target picture to a screen for display.

[0073] Specifically, the timing controller receives the second picture sent by the graphics card, that is, the original picture with reduced resolution, and receives the additional picture that needs to be displayed simultaneously, that is, the first picture. Since the resolution of the second picture is smaller than that of the original picture, the space occupied by the second picture is also reduced. The reduced part is spliced ​​with the first picture to obtain a complete picture with the original resolution. The spliced ​​image with the original resolution includes the first picture (the additional picture in the background technology) and the second picture (the original picture with reduced resolution), achieving the effect of displaying the two pictures simultaneously without blocking or covering each other. Moreover, the first picture and the second picture in the target picture obtained after splicing can both be kept updated, overcoming the shortcomings of the prior art in which part of the original picture's content is covered or blocked and the original picture can no longer be updated.

[0074] Through this embodiment, when the timing controller receives a command to display the first screen, i.e., update the screen, it can reduce the original resolution of the screen to a preset resolution, and send the preset resolution to the graphics card, so that the graphics card outputs a screen with the preset resolution, i.e., the second screen. The timing controller receives the first screen and the second screen, and splices the first screen and the second screen into a screen with the original resolution to obtain a target screen, and sends the target screen to the screen for display. Compared with the device in the prior art, in which when two screens are displayed simultaneously, one screen will cover the information of the other screen and the information of the covered screen can no longer be updated, the present disclosure can display the information of two screens at the same time, the information of one screen will not be covered or blocked, and both screens can be kept updated without affecting each other. Therefore, it can solve the problem in the prior art that when two screens are displayed simultaneously, the information of one screen is blocked, and the purpose of displaying the information of two screens at the same time is achieved.

[0075] In a specific implementation, the timing controller further includes a first reduction unit, a second reduction unit, and a third reduction unit, wherein the first reduction unit is configured to reduce the row resolution of the original resolution to obtain the preset resolution; the second reduction unit is configured to reduce the column resolution of the original resolution to obtain the preset resolution; and the third reduction unit is configured to reduce the row resolution and the column resolution of the original resolution to obtain the preset resolution. The device reduces the parameter of the original resolution by reducing the row resolution, the column resolution, or both the row resolution and the column resolution. This allows the original resolution to be reduced in a variety of ways, so that the reduced resolution can be allocated to a subsequent first screen that needs to be displayed additionally. This allows the first screen and the subsequent second screen to be spliced ​​in any of the above-mentioned ways, thereby increasing the diversity and flexibility of screen display.

[0076] In some optional embodiments, if the original resolution is 1920×1280, the row resolution is reduced to obtain a preset resolution, for example, 720×1280; the column resolution is reduced to obtain a preset resolution, for example, 1920×1080; and both the row resolution and the column resolution are reduced to obtain a preset resolution, for example, 720×1080. Of course, in actual application, the preset resolution can be set according to the actual application scenario, that is, this disclosure does not specifically limit the value of the preset resolution.

[0077] In order to splice the first picture and the second picture according to a preset resolution so that the first picture and the second picture can be displayed simultaneously after splicing, the above-mentioned timing controller also includes a first splicing unit, a second splicing unit and a third splicing unit, wherein the first splicing unit is used to splice the first picture and the second picture up and down to obtain the above-mentioned target picture when the above-mentioned timing controller reduces the row resolution of the above-mentioned original resolution; the second splicing unit is used to splice the first picture and the second picture left and right to obtain the above-mentioned target picture when the above-mentioned timing controller reduces the column resolution of the above-mentioned original resolution; the third splicing unit is used to embed and splice the first picture and the second picture to obtain the above-mentioned target picture when the above-mentioned timing controller reduces the row resolution and the column resolution of the above-mentioned original resolution. The device splices the received first and second pictures according to the above-mentioned resolution reduction device, that is, the preset resolution. In this way, the part of the second picture whose resolution is reduced can be compensated by the first picture according to the preset resolution, and the target picture with the complete original resolution can be obtained by splicing. Furthermore, the first and second pictures can fill the entire screen picture while making the first and second pictures completely displayed without overlapping or blocking each other, thereby realizing the display of the target picture more flexibly.

[0078] Specifically, after the second picture is obtained by reducing the resolution by any of the above-mentioned devices, if the preset resolution is obtained by a device for reducing the row resolution, it can be understood that the number of rows of the second picture is reduced. In this case, the first picture is spliced ​​by compensating for the reduced row resolution, which can be specifically: the first picture is placed above the second picture or the first picture is placed below the second picture, that is, the top and bottom splicing method, for example: the original resolution is 1920×1280, the preset resolution, that is, the resolution of the second picture is 720×1280, then the resolution of the first picture is 1200×1280; if the preset resolution is obtained by a device for reducing the column resolution, it can be understood that the number of columns of the second picture is reduced. When the number of columns is reduced, the first picture is spliced ​​by compensating for the reduced number of columns. Specifically, the first picture is placed on the left of the second picture or the first picture is placed on the right of the second picture, that is, left-right splicing. For example, if the original resolution is 1920×1280 and the preset resolution, that is, the resolution of the second picture, is 1920×1080, then the resolution of the first picture is 1920×200. If the preset resolution is obtained by reducing the row resolution and the column resolution, it can be understood that the number of rows and columns of the second picture are reduced. In this case, the first picture needs to make up for the reduced number of rows and columns, which can be called embedded splicing. For example, if the original resolution is 1920×1280 and the preset resolution, that is, the resolution of the second picture, is 720×1080, then the resolution of the first picture is 1200×200.

[0079] The timing controller further includes a first sending unit and a second sending unit, wherein the first sending unit is configured to, upon receiving a command to exit the display of the first screen, cause the timing controller to send the original resolution and an interrupt signal to the graphics card, so that the graphics card outputs a screen with the original resolution to obtain a third screen, and then send the third screen to the timing controller, wherein the command to exit the display of the first screen is a command indicating exiting the first screen; and the second sending unit is configured to cause the timing controller to send the third screen to the screen for display. When exiting the display of the first screen, the device continues to restore the original resolution and causes the graphics card to output the screen with the original resolution, which is then output to the screen for display. In this way, when exiting the display of the first screen, the first screen is no longer displayed, and the screen with the original resolution, i.e., the third screen, continues to be displayed.

[0080] In a specific implementation, after the first screen is no longer needed for display, indicating that the display of the additional screen is to be exited, the timing controller receives a command indicating the exit of the first screen display, i.e., the first screen display command. The timing controller then sends the initial native resolution to the graphics card, causing the graphics card to no longer output the second screen according to the preset resolution, but instead output the third screen at the native resolution. This third screen is the original screen mentioned above, i.e., the second screen at the native resolution. The graphics card sends the third screen to the timing controller, which then sends the third screen to the screen for display, thereby returning the screen to its original display (the original screen). The graphics card and the timing controller communicate via an EDP (Embedded Display Port, a digital interface used in laptops and tablets) link. If the resolution needs to be changed, the timing controller sends an HPD IRQ (hot plug interrupt request, HPD Interrupt Request, referred to as HPD IRQ) and the preset resolution or the native resolution to the graphics card, causing the graphics card to reconfigure the EDP link according to the preset resolution or the native resolution, causing the graphics card to output the preset resolution or the native resolution to the timing controller.

[0081] In order to timely update the first and second images in the target image, in some embodiments, the timing controller further includes a first updating unit and a second updating unit, wherein the first updating unit is configured to update the first image in the target image upon receiving the updated first image; and the second updating unit is configured to update the second image in the target image upon receiving the updated second image. The device updates the first and second images upon receiving the updated first and second images, thereby timely updating the target image and updating both the first and second images, thereby avoiding the problem of one image failing to be updated when the two images are displayed simultaneously, resulting in the user not being able to obtain the updated image information.

[0082] In some optional embodiments, the current screen displays the target screen, i.e., the first screen and the second screen, and when each screen is dynamic, the screen itself needs to be updated in real time. The above steps can update the first screen in real time when the updated first screen is received, and update the second screen in real time when the updated second screen is received. When the updated first screen and the updated second screen are received at the same time, both the first screen and the second screen are updated to ensure that the user can obtain information about the first screen and the second screen at the same time. As mentioned in the background technology, in the prior art, one screen will be blocked or covered, and the blocked or covered screen cannot be updated in real time. In this way, the user can no longer continue to obtain information about the covered screen, and can only obtain information about the screen above the covered screen, resulting in a poor user experience.

[0083] In some embodiments, the timing controller further includes a first receiving unit and a third sending unit, wherein the first receiving unit is configured to, upon receiving a screen update command and before the timing controller reduces the original resolution to a preset resolution, cause the timing controller to receive a fourth frame sent by the graphics card, wherein the fourth frame is the last frame received by the graphics card before the timing controller reduces the original resolution to the preset resolution; and the third sending unit is configured to send the fourth frame to the screen for display. The device sends the fourth frame, the last frame received at the original resolution, to the screen for display before simultaneously displaying the first and second frames. This prevents the screen from stopping displaying if the target frame, the combination of the first and second frames, has not yet been loaded.

[0084] Specifically, the timing controller requires a certain buffer period to reduce the original resolution to the preset resolution and receive the first and second images. Even if it is a very small period of time, the screen cannot stop displaying the image, such as a black screen, etc., which will make the user experience worse. Therefore, when the timing controller receives the above-mentioned update screen command, the last frame of the original resolution sent by the graphics card, that is, the original image, is sent to the screen for display. That is, during this buffer period, the screen displays the image with the original resolution.

[0085] To accurately splice the first and second images, the timing controller further includes a second receiving unit configured to receive attribute information of the first image sent by the mainboard controller. The attribute information includes at least position information and color information of the first image. The device also receives the attribute information of the first image to better splice the first and second images based on the attribute information.

[0086] In some optional embodiments, since the first picture needs to be spliced ​​with the second picture, the first picture needs to have position information. At the same time, the timing controller also needs to synchronously receive color information of the first picture, etc., collectively referred to as attribute information. Based on the above position information, the timing controller can better splice the first picture and the second picture.

[0087] In a specific implementation, the second image is the image output by the graphics card after receiving an interrupt signal, interrupting the connection link with the timing controller and generating a new connection link based on the preset resolution. The interrupt signal is a signal that controls the interruption of the connection link between the timing controller and the graphics card. The timing controller of the device instructs the graphics card to output an image at the preset resolution by sending the interrupt signal, thereby causing the graphics card to output the image after the resolution is changed, i.e., the second image, thereby further splicing the first image and the second image.

[0088] Specifically, as mentioned above, the transmission is performed between the graphics card and the timing controller through the EDP link. When the resolution needs to be changed, the timing controller sends the HPD IRQ and the preset resolution or the original resolution to the graphics card (the preset resolution is sent in the above step) to enable the graphics card to reconfigure the EDP link according to the above preset resolution, so that the graphics card outputs the picture of the preset resolution, that is, the second picture to the timing controller.

[0089] The timing controller includes a processor and a memory. The first receiving unit, the second receiving unit, and the like are stored in the memory as program units. The processor executes the program units stored in the memory to implement corresponding functions. The modules are all located in the same processor; alternatively, the modules can be located in different processors in any combination.

[0090] The processor contains a kernel, which calls the corresponding program unit from the memory. One or more kernels can be set, and by adjusting the kernel parameters, information on two screens can be displayed simultaneously.

[0091] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
