[0024] like Figure 1 As shown, a dual 8K image display device according to an embodiment includes:

[0025] Processor 10, image display processing module 20, first display interface 30 and second display interface 40; processor 10 is connected to image display processing module 20, and image display processing module 20 is connected to first display interface 30 and second display interface 40 respectively;

[0026] The processor 10 is configured to instruct the image display processing module 20 to read image data to be displayed in response to the image display signal; the processor 10 meets a first preset performance condition;

[0027] The image display processing module 20 is configured to perform image generation processing on the image data to be displayed to obtain the image to be displayed; the image display processing module 20 meets the second preset performance condition;

[0028] The first display interface 30 is used to display the image to be displayed on the first display device connected to the first display interface 30; the second display interface 40 is used to display the image to be displayed on the second display device connected to the second display interface 40; the image resolution of the first display device and the image resolution of the second display device are both 8K.

[0029] The processor 10 is the central processing unit of the dual 8K image display device. The image data corresponding to the image to be displayed at a higher resolution has richer image information. Therefore, in order to more quickly respond to the image display signal to instruct the image display processing module 20 to read the image data to be displayed, thereby ensuring the timeliness and real-time performance of the image display, the processor 10 should have higher performance. Therefore, the processor 10 should meet the first preset performance condition.

[0030] Specifically, the processor 10 is configured to instruct the image display processing module 20 to read the image data to be displayed from a corresponding storage location in response to the image display signal.

[0031] Optionally, the image data to be displayed may be static image data or video image data; correspondingly, the image to be displayed may be a static image or a video image.

[0032] Optionally, the image to be displayed may be a monitoring image, a medical image, or an industrial design image.

[0033] The first preset performance condition is used to ensure that the performance of the processor 10 can meet the requirements of quickly responding to image display signals. Specifically, the first preset performance condition should ensure that the performance of the processor 10 can be used to process 8K resolution image data to be displayed.

[0034] Optionally, the first preset performance condition can be determined by at least one performance parameter of the processor 10, and the at least one performance parameter of the processor 10 includes the clock frequency, number of cores, number of threads, cache size, power consumption, number of concurrent tasks, memory frequency supported by the processor 10, memory bandwidth supported by the processor 10, maximum memory capacity supported by the processor 10, number of memory channels supported by the processor 10, or other parameters related to the performance of the processor 10; exemplarily, the first preset performance condition can represent at least one of the following conditions: the clock frequency of the processor 10 satisfies the first preset frequency condition, the number of cores satisfies the first preset quantity condition, the cache size satisfies the second preset quantity condition, the power consumption satisfies the preset power consumption condition, the number of concurrent tasks satisfies the third preset quantity condition, the memory frequency supported by the processor 10 satisfies the second preset frequency condition, the memory bandwidth supported by the processor 10 satisfies the first preset rate condition, the maximum memory capacity supported by the processor 10 satisfies the preset fourth preset quantity condition, and the number of memory channels supported by the processor 10 satisfies the fifth preset quantity condition.

[0035] Optionally, the first preset performance condition may also directly characterize the type of the processor 10 .

[0036] For example, when the first preset performance condition is determined by at least one performance parameter of the processor 10, the first preset performance condition may characterize that the clock frequency of the processor 10 is 1.60 GHz to 3.40 GHz, it has four cores, a cache size of 16MB, and supports DDR4 memory with a memory frequency of 3200MHz...; when the first preset performance condition directly characterizes the type of the processor 10, the first preset performance condition may characterize that the processor 10 is an X86 processor.

[0037] The image display processing module 20 is a key component in the dual 8K image display device. The image display processing module 20 can ensure that the image to be displayed has accurate color, contrast and clarity when displayed in the first display device and the second display device respectively. Optionally, the image display processing module 20 is a graphics card. The image data to be displayed corresponding to the image to be displayed with a higher image resolution has richer image information. Therefore, in order to have sufficient image display processing capabilities to process rich image information, to process the image data to be displayed and obtain a high-resolution image to be displayed, and to ensure that the image to be displayed has sufficient smoothness, response speed and display quality when displayed in the first display device and the second display device respectively, the image display processing module 20 should have higher performance. Therefore, the image display processing module 20 should meet the second preset performance condition.

[0038] The second preset performance condition is used to ensure that the performance of the image display processing module 20 can meet the requirements of 8K resolution image processing and display.

[0039] Optionally, the second preset performance condition can be determined by at least one performance parameter of the image display processing module 20, and the at least one performance parameter of the image display processing module 20 includes the clock frequency, acceleration frequency, number of stream processors 10, video memory capacity, video memory bandwidth, memory bandwidth or other parameters related to the performance of the image display processing module 20. Specifically, the clock frequency of the image display processing module 20 refers to the clock frequency of the graphics processing unit (GPU); exemplarily, the second preset performance condition can represent at least one condition of the memory interface in which the clock frequency of the image processing display module satisfies the third preset frequency condition, the acceleration frequency satisfies the fourth preset frequency condition, the number of stream processors 10 satisfies the sixth preset number condition, the video memory capacity satisfies the seventh preset number condition, the video memory bandwidth satisfies the second preset rate condition, and the memory bandwidth satisfies the eighth preset number condition.

[0040] Optionally, the second preset performance condition may also directly characterize the type of the image display processing module 20 .

[0041] Exemplarily, when the second preset performance condition is determined by at least one performance parameter of the image display processing module 20, the second preset performance condition may characterize that the clock frequency of the image display processing module 20 is greater than or equal to 1.5 GHz, the acceleration frequency is greater than or equal to 1.8 GHz, it has 2048 stream processors 10, and the video memory capacity is greater than or equal to 16 GB...; when the second preset performance condition directly characterizes the type of the image display processing module 20, the second preset performance condition may characterize that the image display processing module 20 is an independent graphics card, a professional graphics card, or a mobile graphics card.

[0042] The first display interface 30 and the second display interface 40 have different interface types, which may include a DP (DisplayPort) interface, a Type-C interface, an HDMI interface, or other interface types that can support 8K resolution images. Specifically, since the image resolution of the first display device connected to the first display interface 30 and the image resolution of the second display device connected to the second display interface 40 are both 8K, the first display interface 30 and the second display interface 40 should meet the image display function of 8K resolution.

[0043] The first display device is a display device equipped with a connection cable specifically adapted for the first display interface 30. The second display device is a display device equipped with a connection cable specifically adapted for the second display interface 40. Both the first and second display devices are located outside the dual 8K image display apparatus, that is, the first and second display devices are external devices to the dual 8K image display apparatus. Both the first and second display devices meet 8K resolution requirements. For example, the display devices may be monitors, televisions, projectors, and the like.

[0044] Optionally, the first display device or the second display device may display the image to be displayed separately, or both the first display device and the second display device may display the image to be displayed. That is to say, the image to be displayed in this embodiment is displayed by the first display device and / or the second display device, and this embodiment does not impose any restrictions here.

[0045] Specifically, the image resolution of the first display device and the image resolution of the second display device are both 8K. Since the 8K resolution has 7680×4320 pixels ≈ 33 million pixels, the 8K resolution provides an extremely high pixel density for the image and can display extremely delicate image details in the image. Therefore, this embodiment is suitable for large-screen display of the image to be displayed by the first display device and the second display device or high-definition display of the image to be displayed.

[0046] Specifically, the dual 8K image display device provided in this embodiment can be an embedded computer.

[0047] In this embodiment, a dual 8K image display device includes a processor, an image display processing module, a first display interface, and a second display interface; the processor is connected to the image display processing module, and the image display processing module is connected to the first display interface and the second display interface respectively; the processor is configured to respond to an image display signal to instruct the image display processing module to read image data to be displayed; the processor meets a first preset performance condition; the image display processing module is configured to perform image generation processing on the image data to be displayed to obtain an image to be displayed; the image display processing module meets a second preset performance condition; the first display interface is configured to display the image to be displayed on a first display device connected to the first display interface; the second display interface is configured to display the image to be displayed on a second display device connected to the second display interface; the image resolution of the first display device and the image resolution of the second display device are both 8K. The dual 8K image display device provided in this application includes different types of first and second display interfaces, and the first display device connected to the first display interface and the second display device connected to the second display interface both have high image resolutions. Therefore, with the cooperation of the high-performance processor and the high-performance image display processing module, 8K resolution images can be displayed on different display devices through different types of display interfaces.

[0048] In an exemplary embodiment, Figure 2 As shown, a first common-mode inductor 50 is provided between the image display processing module 20 and the first display interface 30. The first common-mode inductor 50 is used to suppress electromagnetic interference noise received when the image to be displayed is displayed on the first display device;

[0049] A second common-mode inductor 60 is provided between the image display processing module 20 and the second display interface 40 . The second common-mode inductor 60 is used to suppress electromagnetic interference noise when the image to be displayed is displayed on the second display device.

[0050] The first common-mode inductor 50 is the common-mode inductor corresponding to the first display interface 30, and the second common-mode inductor 60 is the common-mode inductor corresponding to the second display interface 40. A common-mode inductor is an electronic component used to suppress common-mode noise. It consists of two coils of identical size and number of turns symmetrically wound around a common ferrite toroidal core, forming a four-terminal device. This design enables the common-mode inductor to provide high inductance for common-mode signals and low inductance for differential-mode signals. Consequently, when common-mode current flows through the common-mode inductor, the currents in the two coils flow in the same direction, resulting in superposition of magnetic flux. This, in turn, increases the inductance of the common-mode inductor, producing a relatively high inductance for the common-mode signal, ultimately suppressing electromagnetic interference noise.

[0051] Specifically, since high-resolution image data to be displayed requires data transmission based on a higher transmission frequency, the connection line used by the first display device to transmit data to the first display interface 30 and the connection line used by the second display device to transmit data to the second display interface 40 are more susceptible to electromagnetic interference noise, and traditional filters already have technical bottlenecks for high-frequency signals. Therefore, this embodiment uses the first common-mode inductor 50 and the second common-mode inductor 60 to suppress the electromagnetic interference noise that may exist at the first display interface 30 and the second display interface 40, respectively.

[0052] In this embodiment, by respectively providing a first common-mode inductor and a second common-mode inductor between the image display processing module and the first display interface, and between the image display processing module and the second display interface, the electromagnetic interference noise to which the image to be displayed is subjected when displayed on the first display device and the second display device can be suppressed, respectively. Furthermore, the image display quality of the image to be displayed on the first display device and the second display device can be ensured, and it can be ensured that adverse conditions such as screen distortion will not occur.

[0053] In an exemplary embodiment, Figure 3 As shown, a first electrostatic protection module 70 is provided between the image display processing module 20 and the first display interface 30 , and the first electrostatic protection module 70 is used to guide the static electricity existing at the first display interface 30 to the ground;

[0054] A second electrostatic protection module 80 is provided between the image display processing module 20 and the second display interface 40 . The second electrostatic protection module 80 is used to guide static electricity existing at the second display interface 40 to the ground.

[0055] The first ESD protection module 70 corresponds to the first display interface 30, and the second ESD protection module 80 corresponds to the second display interface 40. The ESD protection module is a circuit module used to protect the dual 8K image display device from damage caused by electrostatic discharge (ESD). The ESD protection module includes electrical components such as transistors. When ESD occurs in the dual 8K image display device, the first ESD protection module 70 and / or the second ESD protection module 80 can promptly enter an operational state to discharge a large amount of transient current and / or transient voltage through the ground line, protecting the internal circuits of the dual 8K image display device from damage.

[0056] In this embodiment, by respectively providing a first electrostatic protection module and a second electrostatic protection module between the image display processing module and the first display interface and between the image display processing module and the second display interface, the static electricity existing at the first display interface and the second display interface can be respectively guided to the ground line, thereby increasing the electrostatic protection capability of the dual 8K image display device to ensure the safety and reliability of the dual 8K image display device.

[0057] In an exemplary embodiment, a first common-mode inductor is arranged between the image display processing module and the first display interface, a second common-mode inductor is arranged between the image display processing module and the second display interface, a first electrostatic protection module is arranged between the image display processing module and the first display interface, and a second electrostatic protection module is arranged between the image display processing module and the second display interface, the first electrostatic protection module is arranged between the first common-mode inductor and the first display interface, and the second electrostatic protection module is arranged between the second common-mode inductor and the second display interface.

[0058] Specifically, since ESD phenomena usually occur at the display interface, the first electrostatic protection module and the second electrostatic protection module are respectively arranged at positions closer to the first display device and the second display device, that is, the first electrostatic protection module is arranged between the first common-mode inductor and the first display interface, and the second electrostatic protection module is arranged between the second common-mode inductor and the second display interface.

[0059] In this embodiment, the first electrostatic protection module is arranged between the first common-mode inductor and the first display interface, and the second electrostatic protection module is arranged between the second common-mode inductor and the second display interface. Thus, while ensuring that the dual 8K image display device can avoid electromagnetic interference noise and static electricity, it can also provide the dual 8K image display device with a faster electrostatic protection response action, reduce the damage caused by ESD phenomena to the first display interface and the second display interface, and further ensure the safety and reliability of the dual 8K image display device.

[0060] In an exemplary embodiment, the first display interface is a DP interface.

[0061] The DP interface is an interface that supports high-definition digital display interface standards and can support high-resolution and high-refresh rate image displays. Specifically, the DP interface supports 4K and 8K resolution image displays.

[0062] Specifically, in the case that the first display interface is a DP interface, correspondingly, the first display device is a DP interface display device.

[0063] In an exemplary embodiment, the second display interface is a Type-C interface.

[0064] Among them, the Type-C interface is an interface that supports universal serial interface standards. Type-C has the characteristics of fast transmission speed, compact interface, and support for forward and reverse insertion.

[0065] Specifically, in the case that the second display interface is a Type-C interface, correspondingly, the second display device is a Type-C interface display device.

[0066] In this embodiment, the DP interface is used to display one channel of 8K resolution images to be displayed on a first display device, and the Type-C interface is used to display another channel of 8K resolution images to be displayed on a second display device. Thus, the dual 8K image display device can simultaneously support the display function of two channels of ultra-high-definition 8K resolution images, while improving the display compatibility of the dual 8K image display device, it can also meet the user's demand for high-resolution, large-screen image display.

[0067] In an exemplary embodiment, Figure 4 As shown, the device further includes a power delivery module 90 and a power processing module 100 , and the power delivery module 90 is connected to the second display interface 40 and the power processing module 100 respectively;

[0068] The power delivery module 90 is configured to rectify and stabilize the first power supply signal from the second display device to obtain a second power supply signal, and deliver the second power supply signal to the power processing module 100, if the second display device supports reverse power supply to the device through the second display interface 40;

[0069] The power processing module 100 is configured to supply power to a target module or a target device in the apparatus based on the received second power supply signal.

[0070] Among them, the second display device that supports reverse power supply to the dual 8K image display devices through the second display interface 40 can not only display images, but also provide power supply signals for the dual 8K image display devices connected thereto. Therefore, the second display device in this case is particularly suitable for occasions where the number of power supplies or power lines used needs to be reduced due to site restrictions or actual needs, so as to simultaneously realize image display functions and power supply functions.

[0071] For example, the second display device of this embodiment can be used in applications where electrical wiring modification is difficult in environments where dual 8K image display devices are located. This means that electrical wiring modification is impossible, resulting in the dual 8K image display devices being unable to connect to the power supply in that environment. In this case, the second display device can overcome the inability of the dual 8K image display devices to obtain power signals from the power supply in that environment, ensuring that the dual 8K image display devices can still perform normal image display operations. In other words, the dual 8K image display device of this embodiment can be used in environments where dual 8K image display devices are unable to obtain power signals.

[0072] Specifically, in order to realize reverse power supply to the dual 8K image display apparatus based on the first power supply signal of the second display device, the power supply signal is transmitted between the second display device and the power delivery module 90 based on the same data transmission protocol.

[0073] The first power supply signal is a power supply signal provided to the second display device by an external power supply connected to the second display device. For example, the external power supply may be a 220V AC power supply.

[0074] It is easy to understand that the second power supply signal is a power supply signal that has been rectified and voltage stabilized. Therefore, the second power supply signal has higher stability than the first power supply signal.

[0075] The target module can be a module in the dual 8K image display device that needs to obtain a power supply signal to maintain a working state; similarly, the target device can be a device in the dual 8K image display device that needs to obtain a power supply signal to maintain a working state.

[0076] In this embodiment, the dual 8K image display device also includes a power delivery module and a power processing module. When the second display device supports the reverse power supply function of the device through the second display interface, the power delivery module rectifies and stabilizes the first power supply signal from the second display device to obtain a second power supply signal, and transmits the second power supply signal to the power processing module. Then, the power processing module powers the target module or target device located in the device based on the received second power supply signal. In this embodiment, since the second display device can obtain the first power supply signal through the external power supply to reversely supply power to the dual 8K image display device, on the one hand, since the dual 8K image display device does not need to be connected to an external power supply, that is, there is no need to prepare a power cord for the dual 8K image display device, the simplicity and ease of use of the dual 8K image display device can be improved. On the other hand, since the setting position of the second display device has higher flexibility, when the second display device supports the reverse power supply function, the dual 8K image display device is compatible with more occasions. Specifically, even if the electrical circuit of the application site of the dual 8K image display device cannot be modified, resulting in the dual 8K image display device being unable to connect to the power supply in the application site, the first power supply signal can be obtained through the second display device whose placement position can be flexibly set, so that the dual 8K image display device can normally perform image display work.

[0077] In an exemplary embodiment, the image to be displayed is any one of a monitoring image, a medical image, and an industrial design image.

[0078] In one exemplary embodiment, the processor is an Intel X86 CPU.

[0079] Among them, Intel X86 CPU is a microprocessor that follows the x86 instruction set architecture (ISA). Intel X86 CPU supports multiple 32-bit and 64-bit computing modes. This processor architecture is compatible with multiple software ecosystems and is therefore widely used in personal computers, servers, and embedded systems.

[0080] In an exemplary embodiment, the image display signal is a PCIE X16 signal.

[0081] In this embodiment, the image display signal is a PCIE X16 signal. Since the PCIE X16 signal provides 16 data channels and each data channel can transmit high-speed data, high-bandwidth data transmission can be achieved. Therefore, the image display processing module is instructed to read the image data to be displayed based on the PCIEX16 signal, which can improve the reading efficiency of the image data to be displayed. Therefore, the display efficiency of the image to be displayed in the first display device and the second display device can be significantly improved, ensuring that the image display is timely and real-time.

[0082] In an exemplary embodiment, the image display processing module is further used to perform differential processing on two consecutive frames of images to be displayed to obtain a frame difference map; perform binarization processing on the frame difference map to obtain a binary frame difference map; obtain a dynamically changing area in the two consecutive frames of images to be displayed based on the binary frame difference map to generate a frame rate reduction coefficient; and reduce the frame rate of a non-dynamically changing area in the two consecutive frames of images to be displayed based on the frame rate reduction coefficient.

[0083] In another exemplary embodiment, the image display processing module is further configured to reduce the frame rate of the non-human area of ​​the non-dynamically changing area based on the frame rate reduction coefficient.

[0084] In another exemplary embodiment, the image display processing module is also used to: obtain the dynamic change area in two consecutive frames of the image to be displayed, and the degree of dynamic change in the dynamic change area based on the binary frame difference map, so as to generate a frame rate reduction coefficient; the frame rate reduction coefficient is negatively correlated with the degree of dynamic change.

[0085] In this embodiment, the dynamically changing areas of the image to be displayed in two consecutive frames are determined, so as to reduce the frame rate of the static areas of the non-dynamically changing areas. Thus, while improving the display flexibility of high-resolution images, energy saving can be achieved by reducing the frame rate of the static areas of the image with less attention, thereby avoiding the static areas of less attention from consuming a large amount of system resources.

[0086] In an exemplary embodiment, the image display processing module is further configured to:

[0087] When a detection object is determined to be present in the display images displayed on the first display device and the second display device, counting the appearance time of the detection object;

[0088] When the appearance duration of the detection object is greater than or equal to the preset duration, determining the image change rate of the displayed image within the appearance duration;

[0089] When the image change rate is greater than or equal to a preset change rate, the processor generates an alarm signal;

[0090] The above processor is further used to:

[0091] The alarm signal is sent to the administrator terminal of the dual 8K image display device.

[0092] The detection object may be a person.

[0093] Optionally, the preset duration may be 30 seconds, 50 seconds, 1 minute or other durations.

[0094] Optionally, the preset change rate may be 0.5, 0.6, 0.7 or other change rates.

[0095] Optionally, the image change rate may be determined by calculating a comparison result of differences between consecutive frames of the displayed image within a duration of time.

[0096] Optionally, the administrator terminal of the image display terminal may be a smartphone, a pager or other terminal of the administrator of the dual 8K image display device.

[0097] Specifically, counting the appearance time of the detection object can be implemented by a time statistics unit in the image display processing module.

[0098] In an exemplary embodiment, there is a negative correlation between the preset change rate and the monitoring level.

[0099] The monitoring level is determined based on the monitoring area of ​​the dual 8K image display devices. For example, if the stored items in the monitoring area are of high value, the monitoring level is also higher; or if the monitoring area involves residents' privacy, the monitoring level is also higher; while if the monitoring area is a busy road, the monitoring level can be appropriately lowered.

[0100] In this embodiment, when the dual 8K image display device is used in a monitored area, if the detected object appears for a long time and the displayed image changes at a high rate during this time, it indicates that the monitored area may be experiencing an abnormality, such as an illegal act of stealing or damaging public property. In this case, the image display processing device will cause the processor to generate an alarm signal, which is then promptly transmitted to the administrator terminal of the dual 8K image display device. Thus, by promptly notifying the administrator of the abnormality, suspicious behavior in the monitored area can be promptly reported to ensure the safety of the monitored area.
