More specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an exemplary embodiment of the present disclosure provides a tiled display system, which may be a tiled screen 1 shown in fig. 1, including two display devices 10. Both display devices 10 may be complete display means, i.e. each display device 10 may display images independently, for example according to existing display technology, even if not used to form a tiled screen with other display devices.
Referring to fig. 2 together, in the present embodiment, each display device 10 includes a processing module 11, a display module 12, a communication module 13, a sound source module 14, and a sound pickup module 15.
The processing module 11 may be an existing data processing device for a display screen, such as a central processing unit (Central Processing Unit, CPU), a Microprocessor (Microprocessor), etc. The display module 12, the communication module 13, the sound source module 14 and the pickup module 15 are all in signal connection with the processing module 11, so that the display module 12 can display images under the control of the processing module 11, the communication module 13 can establish wireless communication with the outside under the control of the processing module 11, the sound source module 14 can play sound under the control of the processing module 11, and the pickup module 15 can receive audio signals from the outside and transmit the received audio signals to the processing module 11.
In this embodiment, the display module 12 may be an existing display screen such as a liquid crystal display (Liquid Crystal Display, LCD), an organic light emitting diode display (Organic Light Emitting Diode, OLED) display, or the like; the communication module 13 may be an existing wireless communication module such as a Wi-Fi module, a Bluetooth (Bluetooth) module, a near field communication (Near Field Communication, NFC) module, etc.; the sound source module 14 may be an existing audio signal playing device built in the display device, such as a speaker, a loudspeaker, a sound box, etc.; the pickup module 15 may be an existing array microphone built into the display device or other similar pickup device. Since the structures of the display module 12, the communication module 13, the sound source module 14 and the sound pickup module 15 and their connection and communication with the processing module 11 can be all adopted in the prior art, the detailed structures thereof and the connection and communication methods with the processing module 11 need not be repeated here.
In the present embodiment, it is preferable that both the sound source module 14 and the sound pickup module 15 are provided outside the display apparatus 10 so as to emit sound to the outside and receive sound from the outside of the display apparatus 10. For example, as shown in fig. 1, the sound pickup module 15 in the present embodiment includes a plurality of microphones 150 constituting an array, arranged at one side edge (upper side edge as shown in fig. 1) of the outside of the display apparatus 10, for receiving sound transmitted from the outside of the display apparatus 10 under the control of the processing module 11; the sound source module 14 includes a plurality of speakers 140 constituting an array, arranged at the other side edge (lower side edge as shown in fig. 1) opposite to the sound pickup module 15 outside the display apparatus 10, for emitting sound to the outside of the display apparatus 10 under the control of the processing module 11. Of course, the number, positions and arrangement of the speakers 140 in the sound source module 14 and the microphones 150 in the sound pickup module 15 are not limited to those shown in fig. 1, and other numbers, positions and arrangements of the speakers 140 and the microphones 150 are possible in other embodiments.
When it is desired to use the tiled screen 1, wireless communication may be first established between the two display devices 10 through the communication module 13 of the two display devices 10, so that the two display devices 10 can synchronously display images based on the wireless communication therebetween. The specific manner of establishing the wireless communication may be, for example, existing Wi-Fi, bluetooth, NFC, etc., and need not be described herein. After that, the two display devices 10 may respectively emit preset positioning audio signals by using the sound source modules 14 thereof and respectively receive the positioning audio signals emitted from each other by using the pickup modules 15 thereof, and then the processing modules 11 of the two display devices 10 respectively perform sound source positioning on each other according to the parameters of the received positioning audio signals to determine the relative positions of each other, and further determine which portion of the image each display device 10 respectively uses to display according to the determined relative positions of each other. In this way, the two display devices 10 can be used to synchronously display the respective portions of the same image, respectively, to form a large-size combined picture, i.e., to realize a split-screen function.
Referring to fig. 3, an exemplary embodiment of the present disclosure provides a screen splicing method for forming a spliced screen, which may be implemented using the components of the spliced screen 1 described above. In particular, the method may comprise the following steps.
S0, at least two display devices for constituting a tiled screen, such as the display device 10 in the foregoing embodiment, are provided.
S1, establishing wireless communication between the at least two display devices for forming the spliced screen.
One of the display devices is a master device for transmitting display information. Any one device may be used as a master device, and is not limited herein, and may be determined according to connection or communication conditions.
In this embodiment, the steps of the method will be described by taking the spliced screen 1 as an example. Accordingly, the specific operation of step S1 may be to establish wireless communication between the two display devices 10 through the communication module 13 of the two display devices 10 so that the two display devices 10 can synchronously display images based on the wireless communication therebetween. The specific manner of establishing the wireless communication may be, for example, existing Wi-Fi, bluetooth, NFC, etc., and need not be described herein.
S2, sending out a positioning audio signal to at least one other display device by using the at least one display device.
For example, in the present embodiment, the processing module 11 of each display device 10 may control the sound source module 14 thereof to emit a preset positioning audio signal, respectively. The positioning audio signal may be a specific audio signal having preset parameters (e.g., preset frequency ranges, preset keywords, etc.).
S3, receiving the positioning audio signals by at least one other display device, positioning a sound source according to the positioning audio signals, and determining the relative position between the display devices.
In the present embodiment, the pickup module 15 of each display apparatus 10 may receive the localization audio signals from the sound source module 14 of the other display apparatus 10, respectively, and transmit the received localization audio signals to the corresponding processing module 11.
The processing module 11 of each display device 10 first confirms that the positioning audio signal is the positioning audio signal emitted by another display device 10 according to the preset parameter (for example, whether the frequency is within the preset frequency range or whether the frequency contains the preset keyword, etc.) of the received positioning audio signal, so that the pickup module 15 can be prevented from mistaking the external noise received at the same time as the positioning audio signal.
After the processing module 11 of one display device 10 confirms that the localization audio signal received by the sound pickup module 15 of the display device 10 is indeed the localization audio signal emitted by the other display device 10, the sound source localization of the other display device 10 can be performed based on the received localization audio signal. The specific sound source localization method may be an existing method, for example, the pickup module 15 used in the present embodiment is composed of a plurality of microphones 150 forming an array, so that sound source localization can be performed on another display device 10 by using the existing sound source localization method based on the array microphones according to the localization audio signal received by the pickup module 15, and the specific means are not necessary to be described. By the sound source localization means, each display device 10 can judge the relative position of itself and another display device 10.
After each display device 10 completes sound source localization and determines the relative position of itself and another display device 10, its processing module 11 may control the communication module 13 to send confirmation information to the other display device 10, informing the other display device 10 that confirmation of the relative position has been completed. After the other display device 10 receives the confirmation information through the communication module 13, the confirmation information may be displayed through the display module 12 to inform the user, and the display information of the display device 10, such as a specific image portion displayed thereon, is adjusted according to the confirmation information.
It will be understood that, for a plurality of display devices in the spliced screen, the specific execution sequence of the steps S2 and S3 may be sequentially executed between the display devices, for example, in this embodiment, a first display device 10 of the two display devices 10 may first send a positioning audio signal to a second display device 10, the second display device 10 receives the positioning audio signal and then performs sound source positioning, and after determining the relative positions of the second display device and the first display device 10, confirmation information is sent to the first display device 10; then, the second display device 10 sends out a positioning audio signal to the first display device 10, the first display device 10 receives the positioning audio signal and then performs sound source positioning, and after determining the relative positions of the first display device 10 and the second display device 10, confirmation information is sent out to the second display device 10. For other embodiments using more display devices, each display device may be used in turn to emit a positioning audio signal for sound source positioning by other display devices in this order. In this way, the mutual interference of the positioning audio signals sent by different display devices 10 can be avoided, and the accuracy of sound source positioning is improved.
It will be appreciated that, for a plurality of display devices in the spliced screen, the specific execution sequence of the steps S2 and S3 may be executed simultaneously between the display devices, for example, in this embodiment, two display devices 10 may be used to simultaneously send positioning audio signals to each other, and sound source positioning is performed simultaneously after receiving the positioning audio signals sent from each other respectively to determine the relative positions of the two display devices, so that the working efficiency may be improved. For other embodiments using more display devices, sound source localization may also be performed in this manner between more than two display devices simultaneously. It will be appreciated that in this case, in order to prevent the positioning audio signals emitted by the different display devices 10 from interfering with each other, the positioning audio signals of the different display devices 10 should be set to have different audio parameters, respectively, so as to be distinguished from each other.
For the processing module 11 of each display device 10, determining the relative position of the display device 10 where the processing module 11 itself is located (hereinafter referred to as the own display device) among the plurality of display devices according to the positioning audio signal may include: and determining the relative position of the display equipment according to the directions and the quantity of the positioning audio signals sent by other display equipment. The number of other display devices can be determined according to the parameter types of other positioning audio signals received by the display device, and the relative positions of the display device relative to other display devices can be determined according to the direction and the azimuth of the positioning audio, for example, how many other display devices are respectively arranged in the upper, lower, left, right, upper left, upper right, lower left and lower right directions of the display device can be determined, so that the relative positions of the display device can be judged.
S4, determining the image parts which should be respectively displayed by each display device according to the determined relative positions among the display devices.
After the relative positions of the display devices are determined, the step S4 can be implemented through the existing split screen image segmentation algorithm, and detailed means are not needed. In the present embodiment, this step S4 is used to determine which half of the image displayed by each display device 10, respectively. It is clear that in other embodiments, if more display devices are used, this step S4 may also be used to determine respectively which specific part of the several parts of the same image each display device is used to display.
After determining the relative position, each display device 10 may send its own relative position and address information (e.g., IP address, MAC address) as confirmation information to other display devices 10. In order to save the calculation power of the whole system, any one of the display devices 10 can be selected as a main device, and when the main device receives the confirmation information of the other display devices 10, the main device can only determine the information part which should be displayed by each display device 10 according to the relative position and address information of each display device 10 and send a corresponding instruction to each display device 10, so as to complete the tiled display.
And S5, respectively displaying the image parts which should be displayed by the display device by using the at least two display devices.
In the present embodiment, after determining the image portions that should be displayed by each display device 10, respectively, the display module 12 of each display device 10 can be controlled by the processing module 11 of that display device 10 to display the image portions that should be displayed by that display device 10. Thus, each display device 10 can be used to display each portion of the same image, so as to form a large-size combined picture, i.e. to realize the function of a spliced screen. During the display process, the image display of at least two display devices 10 can be kept synchronous by means of the wireless communication established between at least two display devices 10 through the communication module 13 thereof, so that each display device 10 always displays different parts of the whole image respectively.
In the tiled display system (i.e., the tiled screen 1) and the screen stitching method thereof provided in the foregoing embodiments of the present disclosure, the display devices 10 of the tiled screen 1 first establish mutual communication through a wireless communication manner, then determine the relative positions of each other through a sound source positioning manner, and further determine, according to the determined relative positions, image portions that should be displayed by each display device 10, so that each display device 10 can be used to synchronously display each portion of the same image, respectively, to form a large-size combined picture, that is, to realize the tiled screen function. Obviously, in the above embodiment provided by the present disclosure, when each display device 10 is assembled into the spliced screen 1, a connecting line is not required to be added between the display devices 10, so that the structure is simple and the operation is convenient; the means of sound source localization is adopted in determining the relative positions between the respective display devices 10, and since the existing display devices are generally built-in with the speakers and microphones in the form of arrays, the means of sound source localization can be realized by built-in components of the existing display devices without adding special localization sensors such as infrared sensors or the like, and without increasing the cost. Therefore, compared with the prior art, the embodiment of the disclosure realizes the spliced screen with simpler structure and lower cost.
Referring to fig. 4, an exemplary embodiment of the present disclosure provides another tiled display system, which may be the tiled screen 2 shown in fig. 4, the tiled screen 2 also being configured with the same display device 10 as in the previous embodiment, but the tiled screen 2 is different from the tiled screen 1 in that it includes four display devices 10, the four display devices 10 are tiled together according to a "field" shape to form the tiled screen 2, and it is apparent that the tiled screen 2 thus formed has a larger size and a more regular shape than the tiled screen 1, and a better display effect can be obtained.
The screen splicing method of the spliced screen 2 may also refer to the screen splicing method provided in the foregoing embodiment. In particular, when each display device 10 emits a positioning audio signal when step S3 of the method is performed for the stitched screen 2, it is preferable that the positioning audio signal is received by the respective pick-up modules 15 of the other three display devices 10 simultaneously, and sound source positioning is performed to determine the relative position between the respective display devices 10 emitting the positioning audio signal. This allows more references to be obtained for sound source localization of each display device 10, and the localization results are more accurate.
It will be appreciated that in other embodiments, other numbers of display devices 10 may be used to form the tiled screen, and the tiled shape of the tiled screen is not limited to the shapes of the tiled screen 1 and the tiled screen 2, but may be implemented with reference to the tiled methods provided in the foregoing embodiments.
In the above embodiment, the parameter information (such as size, shape, resolution, etc.) of each spliced screen may or may not be identical. During splicing, the display data and the working parameters of each spliced screen can be automatically adjusted according to the relative position, the size, the resolution and the shape of each spliced screen. According to the scheme provided by the embodiment, a plurality of spliced screens with inconsistent sizes, resolutions and shapes can be spliced to form a larger display picture.
The foregoing description is only a partial embodiment of the present disclosure, and is not intended to limit the scope of the present disclosure, and all equivalent devices or equivalent process changes made by the disclosure and the accompanying drawings, or direct or indirect application in other related technical fields, are equally included in the scope of the patent protection of the present disclosure.
