[0003] This application relates to the field of image display technology, and in particular to a dual 8K image display device and image display system. Background Technology

[0004] With the rapid development of image display technology, existing technologies generally support 2K and 4K resolutions, which are sufficient for the image clarity requirements of everyday life. However, with the rapid development of fields such as medical imaging, industrial design, and video surveillance, these fields have placed higher demands on image display resolution. Clearly, 2K and 4K resolutions are insufficient to meet the image quality requirements of these fields.

[0005] With the rapid development of image display technology, although there is a demand for higher resolution displays, such as 8K resolution which can provide finer image details and a wider field of view, current computer systems still face significant challenges in supporting 8K resolution. This limits the advantages of 8K image display. Summary of the Invention

[0027] As shown in Figure 1, one embodiment of a dual 8K image display device includes:

[0028] The processor 10, the image display processing module 20, the first display interface 30, and the second display interface 40 are included; the processor 10 is connected to the image display processing module 20, and the image display processing module 20 is connected to the first display interface 30 and the second display interface 40 respectively.

[0029] Processor 10 is configured to respond to an image display signal to instruct image display processing module 20 to read image data to be displayed; processor 10 satisfies a first preset performance condition;

[0030] Image display processing module 20 is used to perform image generation processing on the image data to be displayed to obtain the image to be displayed; image display processing module 20 meets the second preset performance conditions;

[0031] The first display interface 30 is used to display the image to be displayed on a 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 a 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.

[0032] The processor 10 is the central processing unit of the dual 8K image display device. The image data to be displayed corresponding to the higher image resolution has richer image information. Therefore, in order to respond more quickly to the image display signal to instruct the image display processing module 20 to read the image data to be displayed, so as to ensure the timeliness and real-time performance of the image display, the processor 10 should have high performance. Therefore, the processor 10 should meet the first preset performance condition.

[0033] Specifically, the processor 10 is configured to respond to an image display signal to instruct the image display processing module 20 to read the image data to be displayed from the corresponding storage location.

[0034] Optionally, the image data to be displayed can be static image data or video image data; correspondingly, the image to be displayed can be either a static image or a video image.

[0035] Optionally, the image to be displayed can be a surveillance image, a medical image, or an industrial design image.

[0036] The first preset performance condition is used to ensure that the performance of the processor 10 can meet the requirements of fast response to image display signals. Specifically, the first preset performance condition should ensure that the performance of the processor 10 can be used to process image data to be displayed at 8K resolution.

[0037] Optionally, the first preset performance condition can be determined by at least one performance parameter of the processor 10. 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. For example, the first preset performance condition can characterize at least one of the following conditions: the clock frequency of the processor 10 meets a first preset frequency condition; the number of cores meets a first preset number condition; the cache size meets a second preset number condition; the power consumption meets a preset power consumption condition; the number of concurrent tasks meets a third preset number condition; the memory frequency supported by the processor 10 meets a second preset frequency condition; the memory bandwidth supported by the processor 10 meets a first preset rate condition; the maximum memory capacity supported by the processor 10 meets a preset fourth preset number condition; and the number of memory channels supported by the processor 10 meets a fifth preset number condition.

[0038] Optionally, the first preset performance condition can also directly characterize the type of processor 10.

[0039] 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 the processor 10 as having a clock frequency of 1.60GHz to 3.40GHz, having four cores, having a cache size of 16MB, supporting DDR4 memory with a memory frequency of 3200MHz, etc.; when the first preset performance condition directly characterizes the type of the processor 10, the first preset performance condition may characterize the processor 10 as an x86 processor.

[0040] The image display processing module 20 is a key component in the dual 8K image display device. It ensures accurate color, contrast, and sharpness when the image to be displayed is shown on the first and second display devices respectively. Optionally, the image display processing module 20 is a graphics card. Higher resolution images correspond to image data with richer image information. Therefore, in order to have sufficient image display processing capabilities to process the rich image information and obtain a high-resolution image, and to ensure sufficient smoothness, response speed, and display quality when the image is shown on the first and second display devices respectively, the image display processing module 20 should have high performance. Therefore, the image display processing module 20 should meet the second preset performance condition.

[0041] 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.

[0042] Optionally, the second preset performance condition can be determined by at least one performance parameter of the image display processing module 20. 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). For example, the second preset performance condition can characterize at least one of the following memory interface conditions: the clock frequency of the image processing display module meets the third preset frequency condition, the acceleration frequency meets the fourth preset frequency condition, the number of stream processors 10 meets the sixth preset number condition, the video memory capacity meets the seventh preset number condition, the video memory bandwidth meets the second preset speed condition, and the memory bandwidth meets the eighth preset number condition.

[0043] Optionally, the second preset performance condition can also directly characterize the type of the image display processing module 20.

[0044] For example, 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 the image display processing module 20 as having a clock frequency greater than or equal to 1.5 GHz, a boost frequency greater than or equal to 1.8 GHz, having 2048 stream processors 10, a video memory capacity greater than or equal to 16 GB, etc.; when the second preset performance condition directly characterizes the type of the image display processing module 20, the second preset performance condition may characterize the image display processing module 20 as a discrete graphics card, a professional graphics card, or a mobile graphics card.

[0045] The first display interface 30 and the second display interface 40 have different interface types, which may include DP (DisplayPort), Type-C, HDMI, or other interface types that 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 8K resolution image display function.

[0046] The first display device is a display device equipped with a dedicated connection cable adapted to the first display interface 30. The second display device is a display device equipped with a dedicated connection cable adapted to the second display interface 40. Both the first and second display devices are located outside the dual 8K image display device; that is, the first and second display devices are external devices to the dual 8K image display device. Both the first and second display devices are display devices that meet 8K resolution; for example, the display devices can be monitors, televisions, projectors, etc.

[0047] Optionally, either the first display device or the second display device may display the image to be displayed individually, or both the first display device and the second display device may display the image to be displayed. That is to say, in this embodiment, the image to be displayed is displayed by the first display device and / or the second display device. This embodiment does not impose any limitations on this.

[0048] Specifically, the image resolution of both the first display device and the second display device is 8K. Since 8K resolution has 7680×4320 pixels ≈ 33 million pixels, it provides an extremely high pixel density for the image, which can display extremely fine image details. Therefore, this embodiment is suitable for large-screen display or high-definition display of the image to be displayed on the first and second display devices.

[0049] Specifically, the dual 8K image display device provided in this embodiment can be an embedded computer.

[0050] In this embodiment, the 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, which is connected to both the first and second display interfaces. The processor is used 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 used to perform image generation processing on the image data to be displayed to obtain the image to be displayed. The image display processing module meets a second preset performance condition. The first display interface is used to display the image to be displayed in a first display device connected to the first display interface. The second display interface is used to display the image to be displayed in a second display device connected to the second display interface. The image resolution of both the first and second display devices is 8K. The dual 8K image display device provided in this application includes different types of first and second display interfaces, and both the first display device connected to the first display interface and the second display device connected to the second display interface have high image resolution. Therefore, with the image display processing 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.

[0051] In an exemplary embodiment, as shown in FIG2, 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 when the image to be displayed is displayed on the first display device.

[0052] 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.

[0053] The first common-mode inductor 50 corresponds to the first display interface 30, and the second common-mode inductor 60 corresponds 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 the same size and number of turns symmetrically wound on the same ferrite toroidal core to form a four-terminal device. This design allows the common-mode inductor to provide a large inductance for common-mode signals and a smaller inductance for differential-mode signals. Therefore, when common-mode current flows through the common-mode inductor, the current directions in the two coils are the same, resulting in superposition of magnetic flux. This increases the inductance of the common-mode inductor, providing a relatively large inductance for common-mode signals, ultimately suppressing electromagnetic interference noise.

[0054] Specifically, since high-resolution image data to be displayed requires data transmission based on higher transmission frequencies, the connection lines of the first display device for data transmission with the first display interface 30 and the connection lines of the second display device for data transmission with the second display interface 40 are more susceptible to electromagnetic interference noise. Traditional filters have technical limitations for high-frequency signals. Therefore, in this embodiment, the first common-mode inductor 50 and the second common-mode inductor 60 are used to suppress electromagnetic interference noise that may exist at the first display interface 30 and the second display interface 40, respectively.

[0055] In this embodiment, by 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, respectively, electromagnetic interference noise received by the image to be displayed on the first display device and the second display device can be suppressed, thereby ensuring the image display quality of the image to be displayed on the first display device and the second display device, and ensuring that no screen distortion or other defects occur.

[0056] In an exemplary embodiment, as shown in FIG3, a first electrostatic discharge (ESD) protection module 70 is provided between the image display processing module 20 and the first display interface 30. The first ESD protection module 70 is used to guide the static electricity present at the first display interface 30 to the ground wire.

[0057] A second electrostatic discharge (ESD) protection module 80 is provided between the image display processing module 20 and the second display interface 40. The second ESD protection module 80 is used to guide the static electricity present at the second display interface 40 to the ground wire.

[0058] The first electrostatic discharge (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. An ESD protection module is a circuit module used to protect a dual 8K image display device from damage caused by electrostatic discharge (ESD). The ESD protection module includes electrical components such as transistors. When an ESD event 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 a working state to discharge a large amount of instantaneous current and / or instantaneous voltage through the ground wire, ensuring that the internal circuitry of the dual 8K image display device is not damaged.

[0059] In this embodiment, by providing a first electrostatic discharge (ESD) protection module and a second ESD 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, respectively, the static electricity present at the first display interface and the second display interface can be guided to the ground wire, thereby increasing the ESD protection capability of the dual 8K image display device to ensure the safety and reliability of the dual 8K image display device.

[0060] In an exemplary embodiment, a first common-mode inductor is provided between the image display processing module and the first display interface, a second common-mode inductor is provided between the image display processing module and the second display interface, a first electrostatic discharge (ESD) protection module is provided between the image display processing module and the first display interface, and a second ESD protection module is provided between the image display processing module and the second display interface. In this case, the first ESD protection module is provided between the first common-mode inductor and the first display interface, and the second ESD protection module is provided between the second common-mode inductor and the second display interface.

[0061] Specifically, since ESD phenomena usually occur at the display interface, the first electrostatic discharge (ESD) protection module and the second ESD protection module are respectively positioned closer to the first display device and the second display device. That is, the first ESD protection module is positioned between the first common mode inductor and the first display interface, and the second ESD protection module is positioned between the second common mode inductor and the second display interface.

[0062] In this embodiment, the first electrostatic discharge (ESD) protection module is disposed between the first common-mode inductor and the first display interface, and the second ESD protection module is disposed 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 ESD effects, it can also provide a faster ESD protection response for the dual 8K image display device, reduce the damage caused by ESD phenomena to the first and second display interfaces, and further ensure the safety and reliability of the dual 8K image display device.

[0063] In one exemplary embodiment, the first display interface is a DP interface.

[0064] The DisplayPort (DP) interface is an interface that supports high-definition digital display standards, enabling high-resolution and high-refresh-rate image display. Specifically, the DP interface supports 4K and 8K resolution image display.

[0065] Specifically, when the first display interface is a DP interface, the first display device is a DP interface display device.

[0066] In one exemplary embodiment, the second display interface is a Type-C interface.

[0067] Among them, the Type-C interface is an interface that supports a universal serial interface standard. Type-C features high transmission speed, small interface size, and support for reversible insertion.

[0068] Specifically, if the second display interface is a Type-C interface, then the second display device is a Type-C interface display device.

[0069] In this embodiment, the DP interface is used to display one 8K resolution image to be displayed on the first display device, and the Type-C interface is used to display another 8K resolution image to be displayed on the second display device. Thus, the dual 8K image display device can simultaneously support the display function of two 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.

[0070] In an exemplary embodiment, as shown in FIG4, the device further includes a power delivery module 90 and a power processing module 100, wherein the power delivery module 90 is connected to the second display interface 40 and the power processing module 100 respectively.

[0071] The power supply module 90 is used to rectify and regulate the first power supply signal from the second display device to obtain a second power supply signal when the second display device supports the function of reverse power supply to the device through the second display interface 40, and then send the second power supply signal to the power processing module 100.

[0072] The power processing module 100 is used to supply power to the target module or target device located in the device based on the received second power supply signal.

[0073] 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 to the dual 8K image display devices connected to it. Therefore, the second display device in this case is particularly suitable for occasions where the number of power supplies or power cables used needs to be reduced due to space limitations or actual needs, so as to realize both image display and power supply functions at the same time.

[0074] For example, the second display device of this embodiment can be applied to situations where the electrical wiring of a dual 8K image display device is difficult to modify, meaning that the dual 8K image display device cannot be connected to the power supply of that location due to the inability to modify the electrical wiring. In such cases, the second display device can overcome the defect that the dual 8K image display device cannot obtain a power supply signal from its location, ensuring that the dual 8K image display device can still perform image display normally. That is to say, the dual 8K image display device of this embodiment can be applied to situations where the dual 8K image display device cannot obtain a power supply signal.

[0075] Specifically, in order to enable the first power supply signal from the second display device to provide reverse power to the dual 8K image display device, the second display device and the power supply module 90 transmit the power supply signal based on the same data transmission protocol.

[0076] The first power supply signal is the 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 can be a 220V AC power supply.

[0077] As is easily understood, the second power supply signal is a power supply signal that has undergone rectification and voltage regulation, and thus, the second power supply signal has higher stability than the first power supply signal.

[0078] The target module can be a module in a dual 8K image display device that needs to obtain a power supply signal to maintain its working state; similarly, the target device can be a device in a dual 8K image display device that needs to obtain a power supply signal to maintain its working state.

[0079] In this embodiment, the dual 8K image display device further includes a power supply module and a power processing module. When the second display device supports reverse power supply to the device through the second display interface, the power supply module rectifies and regulates the first power supply signal from the second display device to obtain a second power supply signal, and sends the second power supply signal to the power processing module. Then, the power processing module supplies power to 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 an external power supply to supply power to the dual 8K image display device in reverse, on the one hand, 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, which improves the simplicity and ease of use of the dual 8K image display device. On the other hand, since the placement of the second display device is more flexible, the dual 8K image display device is compatible with more occasions when the second display device supports reverse power supply function. Specifically, even if the electrical wiring of the occasion where the dual 8K image display device is used cannot be modified so that the dual 8K image display device cannot be connected to the power supply in that occasion, the first power supply signal can still be obtained through the second display device, which can be flexibly placed, so that the dual 8K image display device can perform image display work normally.

[0080] In one exemplary embodiment, the image to be displayed is any one of a surveillance image, a medical image, and an industrial design image.

[0081] In one exemplary embodiment, the processor is an Intel x86 CPU.

[0082] The Intel x86 CPU is a microprocessor that follows the x86 instruction set architecture (ISA). The Intel x86 CPU supports multiple 32-bit and 64-bit computing modes. This processor architecture is compatible with a variety of software ecosystems, and is therefore widely used in personal computers, servers and embedded systems.

[0083] In one exemplary embodiment, the image display signal is a PCIe x16 signal.

[0084] 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, it can achieve high-bandwidth data transmission. Therefore, by instructing the image display processing module to read the image data to be displayed based on the PCIe x16 signal, the reading efficiency of the image data to be displayed can be improved. Thus, 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.

[0085] In an exemplary embodiment, the image display processing module is further configured 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 the dynamically changing regions 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 the non-dynamically changing regions in the two consecutive frames of images to be displayed based on the frame rate reduction coefficient.

[0086] In another exemplary embodiment, the image display processing module is further configured to reduce the frame rate of non-human areas in non-dynamically changing areas based on a frame rate reduction coefficient.

[0087] In another exemplary embodiment, the image display processing module is further configured to: obtain the dynamically changing regions in two consecutive frames of the image to be displayed, and the degree of dynamic change of the dynamically changing regions, 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.

[0088] In this embodiment, by determining the dynamically changing areas of two consecutive frames of the image to be displayed, the frame rate of the static areas in the non-dynamically changing areas is reduced. Thus, while improving the display flexibility of high-resolution images, energy saving can also be achieved by reducing the frame rate of static areas with low attention in the image, avoiding the consumption of a large amount of system resources by static areas with low attention.

[0089] In an exemplary embodiment, the image display processing module described above, after the image to be displayed is displayed on the first display device and the second display device, is further configured to:

[0090] When a detected object is identified in the displayed images on the first display device and the second display device, the duration of the detected object's appearance is counted.

[0091] When the duration of the detected object's appearance is greater than or equal to a preset duration, the rate of change of the displayed image within the appearance duration is determined;

[0092] When the rate of change of the image is greater than or equal to a preset rate of change, the processor generates an alarm signal.

[0093] The aforementioned processor is also used for:

[0094] The alarm signal is sent to the management terminal of the dual 8K image display device.

[0095] The object of detection can be a person.

[0096] Optionally, the preset duration can be 30 seconds, 50 seconds, 1 minute, or other durations.

[0097] Optionally, the preset rate of change can be 0.5, 0.6, 0.7 or other rates of change.

[0098] Alternatively, the image change rate can be determined by calculating the comparison of differences between consecutive frames of the displayed image within the duration of its appearance.

[0099] Optionally, the management terminal of the image display terminal can be a smartphone, pager, or other terminal of the management personnel of the dual 8K image display device.

[0100] Specifically, the duration of the detected object's appearance can be achieved through the time statistics unit in the image display processing module.

[0101] In one exemplary embodiment, the preset rate of change is negatively correlated with the monitoring level.

[0102] The monitoring level is determined based on the monitoring area of ​​the dual 8K image display device. For example, when the items stored in the monitoring area are of high value, the monitoring level is also higher; or when 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 reduced.

[0103] In this embodiment, when the dual 8K image display device is applied to a monitoring area, if the duration of the detected object's appearance is long and the rate of image change within that duration is large, it indicates that an abnormal situation may have occurred in the monitoring area. For example, there may be criminals attempting to steal or damage public property. In this case, the image display processing device will cause the processor to generate an alarm signal, which will then be promptly sent to the management terminal of the dual 8K image display device. Thus, by promptly informing the management personnel of the abnormal situation, suspicious behavior in the monitoring area can be reported in a timely manner to ensure the security of the monitored area.
