Description

Display system with display picture function

The invention discloses a display system with the ability to display a picture of a picture, especially a display system for displaying a picture of a picture by superimposing an image.

With the rapid development of computer technology, many powerful processors and displays have also been used to provide users with a variety of sound and light enjoyment and visual experience. For example, the computer can be installed with game software and audio and video playback software, and then connected to the game-specific handle or keyboard to provide users with a visual and auditory gaming experience. However, as the display progresses, the fine-tuning functions of various parameters of the display are becoming more and more abundant. When a user uses a computer for a gaming experience, fine-tuning may be performed for specific display parameters to customize the display. For example, when a user uses a computer for a gaming experience, the control interface generated by the screen may be utilized to enhance the contrast of the screen or use the equalizer to enhance the bass to obtain a more exciting sound and light effect.

When the computer generates a display image, if the user wants to use the control interface to adjust some external parameters, the display image generated by the computer may cause a screen interruption. For example, when a user uses a computer to perform a gaming experience, the generation of the control interface will interrupt the game screen. This reduces the fluency of the game. In another case, when the user uses the computer to perform full-screen video playback (for example, the user is watching a movie), the generation of the control interface will reduce the full-screen image to the window image. After the user adjusts various parameters through the control interface, the user must enlarge the window image to a full screen image again. This reduces the comfort of the visual experience.

The method of displaying the second image includes steps S201 to S206. Any reasonable step change is within the scope of the present invention. The description of steps S201 to S206 is as follows.  <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> Step S201: </td><td> The first computer 10 is triggered by the hotkey HK; /td></tr><tr><td> Step S202: </td><td> The first processor CPU1 controls the first programs PG1 and PG2 and the multiplexer MUX through the first software SW1 to make the control device The CD is connected to the second computer 11 through the multiplexer MUX; </td></tr><tr><td> Step S203: </td><td> The first processor CPU1 generates a notification signal to the second computer 11 And the display device 12; </td></tr><tr><td> Step S204: </td><td> After the second computer 11 receives the notification signal, the second processor CPU2 generates a control interface image; Td></tr><tr><td> Step S205: </td><td> The display device 12 displays the control interface image; </td></tr><tr><td> Step S206: </td ><td> The control unit CD performs parameter control via the control interface image. </td></tr></TBODY></TABLE>

As described herein, the first computer 10 has generated the first image before performing the control interface image generation in steps S201 to S206. For example, the first computer 10 can be a game machine on which the game software has been installed. The user uses the first computer 10 to generate a game screen, which is displayed on the display device 12 and can be regarded as a background image. When the user wants to enable the function of adjusting game parameters or displaying parameters. The first computer 10 can be triggered by the hot key HK according to step S201. As mentioned above, the hotkey HK can be a physical button placed on the computer desk and coupled to the first computer 10. The hot key HK may also be a virtual button or a physical button displayed on the display device 12, and the hot button HK may also be disposed on the control device CD. Then, according to step S202, the first processor CPU1 of the first computer 10 controls the first programs PG1 and PG2 and the multiplexer MUX through the first software SW1, so that the control device CD is connected to the second through the multiplexer MUX. Computer 11. In other words, the control device CD can be used to control the first computer 10, for example to control the gaming machine. When the first computer 10 is triggered by the hot key HK, the control device CD can obtain control of controlling the second computer 11. Moreover, the switching behavior of the control right of the control device CD can be controlled by the software SW1 in the first computer 10. Next, in step S203, the first processor CPU1 in the first computer 10 can generate a notification signal to the second computer 11 and the display device 12. For example, the first computer 10 can use the first software SW1 to transmit a corresponding command to the display device 12 through the data display channel (DDC/CI). The first computer 10 and the second computer 11 can also communicate via a device command signal (Device Command). Next, in step S204, after the second computer 11 receives the notification signal, the second processor CPU2 can generate a control interface image. Subsequently, in step S205, the display device 12 can display a control interface image. As mentioned above, the control interface image of the display device 12 can be generated by the second computer 11. The second computer 11 can transmit the control interface image to the display device 12 using the port P5. In this embodiment, the display device 12 continues to display the first image (for example, the background image of the game screen). However, when the display control interface image is generated, the background image displayed by the display device 12 is not controlled. The interface image is interrupted. In other words, the background image and the control interface image displayed by the display device 12 are continuously operated, and the display screen is not interrupted. Finally, according to step S206, since the display device 12 has already displayed the control interface image, the user can use the control device CD to perform parameter control through the control interface image. For example, when the user wants to adjust the display parameters of the display device 12, the parameters displayed on the control interface image can be adjusted. After the user adjusts the parameters displayed on the control interface image, the adjusted parameters on the control interface image are converted into electrical signals, and transmitted by the second computer 11 to the first computer 10 through the connection port P4 and the connection port P3. After the first computer 10 receives the electrical signal corresponding to the adjusted parameter, the display device 12 can be controlled by the first program PG2.

However, the present invention is not limited thereto, and any form of the first image and the second image are superimposed to form a mother-in-picture, and the first image and the second image are continued in the image displayed by the display device 12. The characteristics of the operation of the earth are all within the scope of the present invention. For example, the first image may be a full screen display movie screen, and the second image may be a pop-up window generated by an external hot key or signal. When the second image is generated, the first image can maintain a full screen display. And, the second image can be superimposed on the first image. Also, as mentioned above, when the first computer 10 is triggered by the hot key HK, the control device CD can obtain control of controlling the second computer 11. Therefore, after the control right of the control device CD is switched, the second image generated by the second computer 11 can be operated by the control device CD, and the first image generated by the first computer 10 cannot be controlled by the control device CD. operating.

As mentioned above, any reasonable step change in steps S201 to S206 belongs to the scope of the present invention. For example, the first computer 10 can also generate a Power Off Signal to the second computer 11. After the second computer 11 receives the shutdown signal, the second processor CPU2 can control the second program by using the second software SW2. The PG3 turns off the power. The second program PG3 can be a system shutdown program, such as a Linux Power Off program. The first software SW1 of the first computer 10 has a function of controlling a plurality of programs. For example, the first software SW1 can control the device control program (the first program PG1, having a keyboard/mouse switching function) to drive the control device CD and/or the multiplexer MUX. The first software SW1 can control a wafer program (a first program PG2 having a function of controlling video playback and a chip module C) to drive the chip module C in the display device 12. For example, the first software SW1 can control the wafer program, adjust at least one video output parameter of the display device 12, and cause the display device 12 to display a corresponding picture. The audio and video output parameters can be picture brightness, picture contrast, display mode, volume, and so on.

Figure 3 is a block diagram of another embodiment of a display system 200 of the present invention. As mentioned above, in the display system 100, the first computer 10 and the second computer 11 can be two independent computers, and the first image and the second image can be independently generated by the first computer 10 and the second computer 11, respectively. . Therefore, the first image and the second image do not interfere with each other. However, the present invention can also integrate components inside the second computer 11 into the first computer 10 to reduce the space occupied by the hardware. To avoid confusion, the component symbols of the first computer are indicated by 10a in Figure 3. The display system 200 includes a first computer 10a, a display device 12, and a control device CD. And, the multiplexer MUX can be disposed within the first computer 10a. The multiplexer MUX may also be disposed outside the first computer 10a. The first computer 10a includes a first processor CPU1, a second processor CPU2, and a first memory M1. The first processor CPU1 and the second processor CPU2 are coupled to the first memory M1. The first memory M1 includes a first software SW1, a second software SW2, at least one first program controlled by the first software SW1 (for example, the first program PG1 and the first program PG2), and at least a second software SW2 controlled by the second software SW2. A second program (for example, the second program PG3). The multiplexer MUX is coupled to the first processor CPU1 and the second processor CPU2. The first processor CPU1 can control the multiplexer MUX through the first software SW1. The display device 12 is coupled to the first computer 10a for displaying images. The control device CD is coupled to the multiplexer MUX. The circuit elements of display system 200 are similar to the circuit elements of display system 100. The difference is that in the display system 200, the second processor CPU 2, the second software SW2, and the second program PG3 in the second computer 11 of the previous embodiment (display system 100) are integrated into the first computer 10a. Therefore, when the first computer 10a is triggered by the hot key HK (which may be a physical hot key or a virtual hot key), the first processor CPU1 may control at least one first program through the first software SW1 (as mentioned in the foregoing a first program PG1 of the keyboard/mouse switching function, and a first program PG2) and a multiplexer having functions for controlling video playback and chip module C, so that the control device CD is coupled to the second processor through the multiplexer MUX CPU2. The display device 12 includes a chip module C coupled to the first processor CPU 1 and the second processor CPU 2 . Similarly, the image displayed by the display device 12 includes the first image generated by the first processor CPU1 and the second image generated by the second processor CPU2. Moreover, similar to the foregoing features, the first image may be a background image, and the second image may be a control interface image. The first image and the second image are displayed on the display device 12 in a manner of a picture of the mother and the child. Moreover, the first image and the second image are continuously operated in the image displayed by the display device 12. In other words, when the display device 12 is displaying the first image (background image) and the second image (control interface image) is generated, the second image may be superimposed on the first image without interfering with the first image. The operation of the image. Since the first image is not interrupted by the second image, the user can obtain a better visual experience.

The method of displaying the second image of the display system 200 is similar to the display system 100 and will not be described herein. Similarly, when the first computer 10a is triggered by the hot key HK, the control of the control device CD will be switched. Therefore, the second image can be operated by the control device CD, and the first image cannot be operated by the control device CD. Moreover, in the method of displaying the second image of the display system 200, the first processor CPU1 may also generate a shutdown signal to the second processor CPU2. The second processor CPU2 can turn off the second processor by using the second program PG3 controlled by the second software SW2 to achieve power saving.

The display system 100 and the display system 200 of the present invention can have various combinations of signals, as long as the first image and the second image are independently generated, and the first image and the second image overlap each other without interfering with each other. The manner in which the technology produces a picture of a child and a child is within the scope of the present invention. For example, as described above, the first image can be defined as a background image, and the second image can be defined as a control interface image. The background image and control interface image can be a picture of the child and is continuously operated. When the first computer 10a is triggered by the hot key HK (which may be a virtual or physical hot key), the first processor CPU may generate a notification signal to the second processor CPU 2 and the display device 12. After the second processor CPU2 receives the notification signal, the second processor CPU2 generates a control interface image. The display device 10 can display a control interface image. The control device CD can be operated using the control interface image. Moreover, although the first image in this embodiment may be defined as a background image and the second image may be defined as a control interface image, the present invention is not limited thereto. For example, the first image may be a full screen displayed movie screen, and the second image may be an instant message pop-up window generated by an external hot key or signal. The first image maintains a full screen display when the second image is generated. And, the second image can be stacked on the first image. In this embodiment, since the display system can use the independently generated first image and the second image to perform image superimposition to generate a picture, the first image and the second image do not interfere with each other and stop. There is also no case where the first image is reduced to a window image by the full screen without warning. Therefore, the display system of the present invention can enhance the visual experience of the user.

Figure 4 is a block diagram of another embodiment of a display system 300 of the present invention. As mentioned above, any reasonable change of hardware or software is within the scope of the present invention. The architecture of the display system 300 of FIG. 4 is similar to the architecture of the display system 100 of FIG. 1 , except that the display system 300 introduces the first image generation unit GPU 1 and the second image generation unit GPU 2 , and also introduces the first The driver PGM1 and the second driver PGM2 drive the corresponding hardware, which are described below. Since the architectures in the first computer 10 and the second computer 11 in the display system 300 are different from the display system 100, in order to avoid confusion. The code for the first computer in display system 300 is referred to herein as 10c, and the code for the second computer is referred to herein as 11c. The display system 300 includes a first computer 10c, a second computer 11c, a display device 12, and a control device CD. The first computer 10c includes a first processor CPU1 and a first image generating unit GPU1. The first image generating unit GPU1 generates a first image IMG1. The second computer 11c includes a second image generating unit GPU2 for generating a second image IMG2. The second computer 11c may also include a second processor CPU2 to control the second image generating unit GPU2. The first image generating unit GPU1 and the second image generating unit GPU2 may generate a wafer for the image on the display card. The first computer 10c may further include a first memory M1 coupled to the first processor CPU1. The first memory M1 includes a first driver PGM1 and a second driver PGM2. In the display system 300, the first driver PGM1 and the second driver PGM2 can be two independently installed programs, or can be two sub-programs integrated by the upper layer software. For example, the first driver PGM1 can be integrated by the first software (upper layer) SW1 and the first program PG1 (lower layer) in the foregoing display system 100. The second driver PGM2 can be integrated by the first software (upper layer) SW1 and the first program PG2 (lower layer) in the display system 100. However, in practical applications, the affiliation of the upper layer software (SW1) and the lower layer programs (PGM1 and PGM2) can also be utilized to achieve the function of the first driver PGM1 and the function of the second driver PGM2, any reasonable software or toughness. Combinations of bodies are within the scope of the present invention. The display device 12 is coupled to the first computer 10c and the second computer 11c, and the display device 12 can display the first image IMG1. As mentioned above, when the first computer 10c is not triggered by the hotkey HK, the first image IMG1 displayed by the display device 12 can be a background image, and the control device CD is coupled to the first computer 10c through the multiplexer MUX.

When the first computer 10c is triggered by the hot key HK, the control device CD is coupled to the second computer 11c via the multiplexer MUX. Subsequently, the display device 12 can simultaneously display the first image IMG1 and the second image IMG2. The user can operate the second image IMG2 through the second computer 11c by using the control device CD. For example, the user can adjust the display parameters or the video output parameters on the second image IMG2 (operation interface image) by using the control device CD. The second computer 11c generates a control signal and transmits the control signal to the first computer 10c via the port 4P4 and the port 3P3. After the first computer 10c receives the control signal, the first processor CPU1 can drive the display device 12 through the second driver PGM2 to present a screen set by the user. In other words, the control signal can adjust at least one of the video output parameters of the display device 12 through the second driver PGM2. Moreover, as mentioned above, when the first computer 10c is triggered by the hot key HK, the control device CD can be coupled to the second computer 11c via the multiplexer MUX. The embodiment may be that when the first computer 10c is triggered by the hotkey HK, the first processor CPU1 in the first computer 10c can switch and couple the multiplexer MUX to the second computer 11c through the first driver PGM1. . Therefore, the control device CD can obtain the control right of the second computer 11c, and the user can control the second computer 11c by using the control device CD, and further trigger the first computer to control the display device 12 to present the screen set by the user. In other words, when the first computer 10c is triggered by the hot key HK, the control of the control device CD will be switched. The second image IMG2 generated by the second computer 11c can be operated by the control device CD, and the first image IMG1 generated by the first computer 10c cannot be operated by the control device CD.

As mentioned above, the first image IMG1 generated by the first image generating unit GPU1 may be a background image, and the second image IMG2 generated by the second image generating unit GPU2 may be an operation interface image. The first image IMG1 and the second image IMG2 may be a picture of a child. Moreover, as shown in FIG. 4, the second image IMG2 may be stacked on the first image IMG1. Since the second image IMG2 and the first image IMG1 can be generated by the independent image generating unit, and the second image IMG2 can be stacked on the first image IMG1, the first image IMG1 and the second image IMG2 do not interfere with each other. Therefore, when the first image IMG1 is displayed on the full screen, the second image IMG2 is generated without causing the window image reduction operation of the first image IMG1 or the screen to be stopped. As a result, the user's visual experience can be improved.

In summary, the present invention describes a display system that can independently generate a first image and a second image, and has a function of superimposing the first image and the second image to generate a picture of the child. Since the first image and the second image do not interfere with each other, when the first image is displayed on the full screen and the second image is generated, the first image does not stop or shrink to the window without warning. . Moreover, the display system of the present invention also introduces the function of the switching control device. When the first computer that generated the first image is not triggered, the control of the first computer is directed to the control device. For example, the user is using a mouse to perform a video game through the game machine. However, when the first computer is triggered to inform the second computer to generate the second image, the control of the second computer is directed to the control device. For example, when the user wants to call the operation interface and adjust the parameters when performing the video game, the parameter can be adjusted through the operation interface generated by another computer. Therefore, since the display system of the present invention can smoothly display the picture of the mother and child and has the function of switching the control of the control device, the visual experience and the operation efficiency of the user can be improved. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
