[0030] Figure 1 A schematic diagram of a display device according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows: A display device 10 includes: an input module 100, an output module 200, a main control module 300, a power amplifier module 400, and multiple speakers 500.

[0031] The input module 100 is used to receive audio data signals and input coordinate signals; the output module 200 is connected to the input module 100 and is used to output the audio data signals; the main control module 300 is connected to both the input module 100 and the output module 200, and the main control module 300 is used to generate output coordinate signals based on the input coordinate signals, and the output coordinate signals are output through the output module 200; the input terminal of the power amplifier module 400 is connected to the input module 100, and the power amplifier module 400 is used to generate audio drive signals based on the audio data signals, and each speaker 500 is connected to the output terminal of the power amplifier module 400; the main control module 300 is also used to control one or more speakers 500 to receive the audio drive signals based on the output coordinate signals, and the audio drive signals are used to drive the speakers 500 to work. Each display device 10 has independent sound output capability.

[0032] It is understandable that when multiple display devices 10 are cascaded sequentially, each display device 10 can transmit complete audio data signals to the next-level display device 10. When the output coordinate signal output by the previous-level display device 10 is transmitted to the next-level display device 10, it becomes the input coordinate signal of the next-level display device 10. Both the input and output coordinate signals can include coordinate parameters. The main control module 300 can use the coordinate parameters in the output coordinate signal to locate the display device 10, and thus control the corresponding speaker 500 to operate based on the location.

[0033] By directly connecting the input module 100 to the output module 200, the audio data signal received by the input module 100 can be completely transmitted to the next stage circuit. Therefore, the signal source providing the audio data signal can provide the audio data signal to multiple display devices 10 through only one data line, significantly reducing the number of cables required. Simultaneously, by generating output coordinate signals for the next stage circuit based on the input coordinate signals by the main control module 300, automatic positioning of the display devices 10 can be achieved. Under the control of the main control module 300, the corresponding speaker 500 can be directly controlled to operate according to the output coordinate signals. No additional intermediate circuits such as sending and receiving cards are needed, reducing the number of signal nodes and further reducing costs and maintenance difficulty.

[0034] In one embodiment, the plurality of speakers 500 include at least one woofer 510, at least one midrange speaker 520 and at least one tweeter 530.

[0035] For example, such as Figure 2 As shown, in some embodiments, a display device 10 includes a woofer 510, two midrange speakers 520, and two tweeters 530. The main control module 300 can control one or more speakers 500 to emit sound simultaneously according to actual needs, thereby forming a mono system, a stereo system, a 2.1-channel system, or a 4.1-channel system.

[0036] Understandably, by increasing the number of speakers by 500, it is possible to form a 5.1 channel system, a 7.1 channel system, or even more sound effect control systems, achieving the diversity of sound control for a single display device.

[0037] For example, multiple display devices 10 are cascaded in sequence. After the main control module 300 of the display device 10 completes the positioning of the display device 10 according to the output coordinate signal or the input coordinate signal, it can also group the multiple display devices 10 according to the coordinate parameters of each display device 10. The same group of display devices 10 can use the same speaker 500 driving strategy, and different groups of display devices 10 can use different speaker 500 driving strategies to form a multi-array distributed sound output system with diverse layouts suitable for actual needs.

[0038] In one embodiment, such as Figure 3 As shown, the power amplifier module 400 includes a power amplifier unit 410 and multiple control switches ( Figure 3 Only control switches S1 and S2 are shown in the diagram. Each control switch corresponds to one of the speakers 500. Each speaker 500 is connected to the power amplifier unit 410 through the corresponding control switch. The control terminal of each control switch is connected to the main control module 300.

[0039] Understandably, the main control module 300 can control the on and off states of each control switch. When a control switch is on, the audio drive signal can be transmitted to the corresponding speaker 500, causing the speaker 500 to emit the corresponding sound. When a control switch is off, the audio drive signal cannot be transmitted to the corresponding speaker 500, causing the speaker 500 to stop working.

[0040] In one embodiment, the display device 10 further includes a driving module 600, which is connected to the input module 100 and the main control module 300 respectively; the input module 100 is further configured to receive image signals, and the output module 200 is further configured to output the image signals; the driving module 600 is configured to obtain an image sub-signal corresponding to the output coordinate signal from the image signal according to the output coordinate signal, and generate a driving signal corresponding to the image sub-signal.

[0041] The display device 10 can use a signal format corresponding to the HDMI protocol to simultaneously transmit audio data signals and image signals.

[0042] Understandably, when multiple display devices 10 are cascaded sequentially, each display device 10 can transmit a complete image signal to the next-level display device 10. When the output coordinate signal from the previous-level display device 10 is transmitted to the next-level display device 10, it becomes the input coordinate signal for the next-level display device 10. The input coordinate signal includes coordinate parameters. Each driving module 600 can use the coordinate parameters in the input coordinate signal to position the display device 10, thereby determining the image area that the display device 10 needs to display. It then obtains the corresponding image sub-signal from the image signal and generates the corresponding driving signal.

[0043] By directly connecting the input module 100 to the output module 200, the image signal received by the input module 100 can be completely transmitted to the next-level circuit. Therefore, the signal source providing the image signal can provide the image signal to multiple display devices 10 through only one data line, significantly reducing the number of cables required. At the same time, by generating the output coordinate signal for the next-level circuit based on the input coordinate signal by the main control module 300, the display device 10 can be automatically positioned. Each display device 10 can automatically obtain the corresponding image sub-signal based on the output coordinate signal through the driver module 600, eliminating the need for intermediate circuits such as additional sending and receiving cards, reducing the number of signal nodes, and further reducing costs and maintenance difficulty.

[0044] In some embodiments, when multiple display devices 10 are cascaded sequentially, the input coordinate signal received by display device 10 may include the coordinate parameters of the previous stage circuit, and the output coordinate signal output by display device 10 may include its own coordinate parameters. Alternatively, the input coordinate signal received by display device 10 may include its own coordinate parameters, and the output coordinate signal output by display device 10 may include the coordinate parameters of the next stage. The input and output coordinate signals can be configured according to actual needs.

[0045] In some embodiments, the main control module 300 includes a microcontroller unit (MCU).

[0046] In one embodiment, such as Figure 4 As shown, the driving module 600 includes a cutting unit 610 and a driving unit 620; the cutting unit 610 is connected to the input module 100 and is used to obtain an image sub-signal corresponding to the output coordinate signal from the image signal according to the output coordinate signal; the driving unit 620 is connected to the cutting unit 610 and is used to generate a driving signal corresponding to the image sub-signal.

[0047] The cutting unit 610 and the driving unit 620 may each include a corresponding chip, and this embodiment does not limit their model, parameters, etc.

[0048] The cutting unit 610 can determine which part of the target image needs to be displayed based on the output coordinate signal, and then obtain the image sub-signal corresponding to the output coordinate signal from the image signal. The driving unit 620 can then output a driving signal corresponding to the image sub-signal to light up each pixel in the display panel connected to the driving unit 620.

[0049] For example, after receiving a 4K resolution image signal, the cutting unit 610 can obtain a 2K resolution image sub-signal from a portion of the 4K image signal, and the driving unit 620 can generate a corresponding driving signal to light up the corresponding display panel according to the resolution of the display panel to be lit.

[0050] In one embodiment, such as Figure 5 As shown, the driving module 600 includes a conversion unit 630, a driving unit 620, and a storage unit 640. The conversion unit 630 is connected to the input module 100 and is used to convert the image signal into a data signal through serial-to-parallel conversion. The driving unit 620 is connected to both the conversion unit 630 and the storage unit 640. The driving unit 620 is used to store the data signal in the storage unit 640, obtain the image sub-signal corresponding to the output coordinate signal from the data signal according to the output coordinate signal, and generate a driving signal corresponding to the image sub-signal.

[0051] The conversion unit 630, the driving unit 620, and the storage unit 640 each include a corresponding chip.

[0052] The image signal may specifically include an HDMI signal, and the data signal may specifically include a Low Voltage Differential Signaling (LVDS) signal or a Time-Limited (TTL) signal. The conversion unit 630 can convert the serial signal to a parallel signal to obtain a data signal based on the image signal, and the driving unit 620 stores the data signal in the storage unit 640. After storing the data signal corresponding to at least one frame of the image, the driving unit 620 can obtain the image sub-signal corresponding to the output coordinate signal based on the stored data signal and the resolution of the display panel to be lit, and generate a driving signal corresponding to the image sub-signal.

[0053] In some embodiments, the driving unit 620 includes a field programmable gate array (FPGA).

[0054] In some embodiments, the storage unit 640 includes a DDR3 storage chip.

[0055] Figure 6A schematic diagram of a display device according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows: A display device 10 includes a display panel 700, and a driving module connected to the display panel 700 for transmitting driving signals to the display panel 700. The display panel 700 may include an LED panel.

[0056] Understandably, the driving signal can be used to illuminate each pixel unit on the display panel 700 and control the color and brightness of the light emitted by each pixel unit to display the corresponding image.

[0057] In one embodiment, such as Figure 7 As shown, the input module 100 of the display device 10 includes a first input terminal 110, a second input terminal 120, and an interface unit 130; both the first input terminal 110 and the second input terminal 120 are connected to the interface unit 130, and the interface unit 130 is connected to the drive module 600, the output module 200, and the main control module 300 of the display device 10, respectively; the first input terminal 110 is used to connect to an external circuit located in a first direction of the display device 10, and the second input terminal 120 is used to connect to an external circuit located in a second direction of the display device 10; wherein, the first direction and the second direction intersect, and both the first direction and the second direction are parallel to the display panel 700.

[0058] Specifically, the interface unit 130 may include an interface chip. The interface unit 130 may include multiple input terminals and multiple output terminals, and when an image signal is received at any one input terminal, all output terminals can output the same image signal.

[0059] In the case of multiple display devices 10 arranged in an array, the first input terminal 110 and the second input terminal 120 can be connected to adjacent display devices 10 in different directions to obtain input coordinate signals from the adjacent display devices 10. It is understood that the first input terminal 110 and the second input terminal 120 can be connected to different display devices 10. Even if the input coordinate signals received by the first input terminal 110 and the second input terminal 120 are different, the main control module 300 can determine its own coordinates based on which input terminal received the input coordinate signal and generate an output coordinate signal corresponding to its own coordinates.

[0060] It should be noted that the display device 10 can also be directly connected to the signal source through the first input terminal 110 or the second input terminal 120 to directly obtain image signals from the signal source.

[0061] In some embodiments, both the first input terminal 110 and the second input terminal 120 include an HDMI interface.

[0062] In some embodiments, the signal source includes electronic devices such as computers and mobile phones.

[0063] Since the signal source can directly provide image signals to the display device 10, the entire image signal transmission path only has two signal nodes (i.e., the signal source and the display device 10), reducing control layers, improving stability, and lowering the maintenance threshold. Each display device 10 is an independent unit, making it convenient and simple to use and maintain.

[0064] In one embodiment, such as Figure 7 As shown, the output module 200 includes a first output terminal 210 and a second output terminal 220.

[0065] The first output terminal 210 and the second output terminal 220 are respectively connected to the input module 100 and the main control module 300; the first output terminal 210 is used to connect to an external circuit located in a third direction of the display device 10 to output image signals and a first coordinate signal; the second output terminal 220 is used to connect to an external circuit located in a fourth direction of the display device 10 to output image signals and a second coordinate signal; wherein, the third direction intersects with the fourth direction, and both the third direction and the fourth direction are parallel to the display panel 700.

[0066] When multiple display devices 10 are arranged in an array, the first output terminal 210 and the second output terminal 220 can be connected to different display devices 10 respectively, but can output the same first coordinate signal and second coordinate signal. The output coordinate signal includes the first coordinate signal and the second coordinate signal.

[0067] In some embodiments, both the first output terminal 210 and the second output terminal 220 include an HDMI interface.

[0068] In some embodiments, the display devices 10 can be connected via an Inter-Integrated Circuit (IIC) bus, and the main control module 300 can use the IIC to transmit image signals and output coordinate signals (input coordinate signals).

[0069] In one embodiment, the third direction is the opposite direction of the first direction, and the fourth direction is the opposite direction of the second direction.

[0070] In the case of an array of multiple display devices 10, if the first and third directions are column directions and the second and fourth directions are row directions, adjacent display devices 10 located in the same column can be interconnected through the first input terminal 110 and the first output terminal 210, and adjacent display devices 10 located in the same row can be interconnected through the second input terminal 120 and the second output terminal 220. When a signal source is connected to a suitable display device 10 and provides an image signal to the display device 10, the first input terminal 110, the second input terminal 120, the first output terminal 210, and the second output terminal 220 can be used to provide an image signal to each display device 10.

[0071] It is understandable that two image signal transmission paths can be formed through the first input terminal 110, the second input terminal 120, the first output terminal 210, and the second output terminal 220. The two paths can serve as backups for each other, and if one path fails, most display devices 10 can still receive the complete image signal.

[0072] In one embodiment, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the fourth direction.

[0073] When the first and second directions are perpendicular to each other, and the third and fourth directions are perpendicular to each other, multiple display devices 10 can form a cross-shaped screen pattern.

[0074] In one embodiment, such as Figure 8 As shown, the input module 100 of the display device 10 includes a first data terminal 140, a first communication terminal 150, and an interface unit 130; the output module 200 of the display device 10 includes a second data terminal 230 and a second communication terminal 240; and the main control module 300 of the display device 10 includes a communication unit. The first data terminal 140 and the second data terminal 230 are both connected to the interface unit 130, and the first communication terminal 150 and the second communication terminal 240 are both connected to the communication unit.

[0075] The first data terminal 140 can be used to receive image signals, the second data terminal 230 can be used to output image signals, the first communication terminal 150 can be used to receive input coordinate signals, and the second communication terminal 240 can be used to transmit output coordinate signals, so as to realize independent signal transmission. Multiple display devices 10 can be interconnected through the first communication terminal 150 and the second communication terminal 240, and communicate with each other through their respective communication units to configure various parameters.

[0076] In some embodiments, both the first communication terminal 150 and the second communication terminal 240 include an RJ45 interface, and the communication unit includes a network communication chip.

[0077] Figure 9 A schematic diagram of a display device according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows: A display device 20 includes a plurality of display devices as described in any of the above embodiments. Figure 9 The diagram shows a first display device 10a, a second display device 10b, a third display device 10c, a fourth display device 10d, a fifth display device 10e, a sixth display device 10f, a seventh display device 10g, an eighth display device 10h, and a ninth display device 10i. Multiple display devices are arranged in an array, with the input module 100 of each display device connected to the output module 200 of the adjacent display device. It is understood that different display devices 20 may each include a different number of display devices 10, and the number of display devices 10 in the vertical direction (i.e., the first and third directions) and the number of display devices 10 in the horizontal direction (i.e., the second and fourth directions) may differ between different display devices 20. The arrangement of the multiple display devices 10 in the display device 20 can be set according to actual needs, and the positioning of each display device 10 can ultimately be completed through the main control module 300 of each display device 10.

[0078] For example, in one embodiment, the first direction is downward, the second direction is leftward, the third direction is upward, and the fourth direction is rightward. The display device 20 includes nine display devices (namely, a first display device 10a, a second display device 10b, a third display device 10c, a fourth display device 10d, a fifth display device 10e, a sixth display device 10f, a seventh display device 10g, an eighth display device 10h, and a ninth display device 10i), which form a three-row, three-column display matrix.

[0079] Signal source 30 can be connected to the first display device 10a located in the lower left corner to provide image signals to the first display device 10a. Since the first input terminal 110 and the second input terminal 120 of the first display device 10a are not connected to other circuits, the first display device 10a can set its own coordinates to (0, 0) and transmit a first coordinate signal containing the (0, 0) coordinates through the first output terminal 210, and transmit a second coordinate signal containing the (0, 0) coordinates through the second output terminal 220. For the second display device 10b located above the first display device 10a, it can receive the first coordinate signal output by the first display device 10a through its first input terminal 110. The first coordinate signal provided by the first display device 10a, containing coordinates (0, 0), is the input coordinate signal of the second display device 10b. The second display device 10b can then confirm its own coordinates as (0, 1). For the fourth display device 10d to the right of the first display device 10a, the second coordinate signal provided by the first display device 10a, containing coordinates (0, 0), is the input coordinate signal of the fourth display device 10d. When the fourth display device 10d receives the second coordinate signal from the first display device 10a through its second input terminal 120, the fourth display device 10d can then confirm its own coordinates as (1, 0). Similarly, the second display device 10b can provide the required input coordinate signals to the third display device 10c and the fifth display device 10e, respectively, and the fourth display device 10d can provide the required input coordinate signals to the fifth display device 10e and the seventh display device 10g, respectively. By analogy, each display device 10 can be automatically positioned according to the input coordinate signal, thereby configuring the coordinates of each display device 10.

[0080] In this embodiment, only one data line is required between the display device 20 and the signal source 30, which can reduce cable costs, reduce wiring complexity, improve stability, and make maintenance more convenient.

[0081] In practical applications, after configuring the coordinates of each display device 10, the coordinate origin can be reset. For example, the coordinates of the third display device 10c located in the upper left corner can be set to (0, 0). Correspondingly, the coordinates of the second display device 10b can be adjusted to (0, 1), the coordinates of the first display device 10a can be adjusted to (0, 2), and the coordinates of the other display devices can be deduced in the same way.

[0082] For example, after the coordinate configuration of each display device 10 is completed, the first display device 10a, the third display device 10c, the seventh display device 10g and the ninth display device 10i can be configured to drive only their respective tweeters 530, the fifth display device 10e can be configured to drive only the woofer 510, and the second display device 10b, the fourth display device 10d, the sixth display device 10f and the eighth display device 10h can be configured to drive only their respective midrange speakers 520, thereby forming a multi-array distributed sound output system with 6 tweeters, 2 midrange speakers and 1 woofer.

[0083] Each display device 10 has configuration parameters saved at the factory. These configuration parameters include the number of horizontal and vertical pixels of the display device. The corresponding image starting point can be obtained by multiplying the number of pixels by the coordinates through the main control module 300.

[0084] For example, if each display device 10 has 480 horizontal pixels and 270 vertical pixels, then the image starting point of the display device with coordinates (1, 0) is (480, 0), the image starting point of the display device 10 with coordinates (0, 1) is (0, 270), the image starting point of the display device 10 with coordinates (1, 1) is (480, 270), and so on.
