DETAILED DESCRIPTION
[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the corresponding component outline, and "far" and "near" refer to the corresponding structure or corresponding component being far away from or from another structure or component; it should be noted that the terms used, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0029] In the related art, in order to install the GPU chip, an external graphics card dock is usually used, which not only requires consumers to spend extra money to purchase the graphics card dock, but also still takes up a certain amount of desktop space, and is not friendly to some users with poor hands-on ability.
[0030] In addition, there are also GPU chips integrated like in notebooks, but they require higher power supply and heat dissipation capabilities, which also takes up space and increases weight and cost.
[0031] The present disclosure aims at the technical problems in the related technology, namely, the pain points that the current external graphics card solutions are not highly integrated and require certain hands-on skills, so as to improve the integration of graphics card modules and displays, reduce desktop space occupancy, and reduce costs, thereby creating a foundation for subsequent technological innovation.
[0032] In order to achieve the above purpose, Figures 1 to 4As shown, an embodiment of the present disclosure provides a display device, which includes a shell 500, a display panel, and a display driver chip 100 disposed inside the shell 500 and connected to the display panel signal. The display device also includes a graphics card module 200, and the graphics card module 200 includes a graphics card chip 210, and the graphics card chip 210 is disposed inside the shell 500 and connected to the display driver chip 100 signal.
[0033] Through the above technical solution, the display device of the present disclosure includes a housing 500, a display panel, and a display driver chip 100 disposed inside the housing 500, and also includes a graphics card module 200, wherein the graphics card module 200 includes a graphics card chip 210, wherein the graphics card chip 210 and the display driver chip 100 are both disposed inside the housing 500 of the display device, and the graphics card chip 210 is connected to the display panel signal through the display driver chip 100, thereby improving the integration of the display device, reducing the desktop space occupied, and reducing the overall cost. At the same time, since the graphics card chip 210 of the graphics card module 200 of the present disclosure can be disposed inside the housing 500 and connected to the display panel through the display driver chip 100, the consumption of video (such as HDMI or DP) cables required to connect the display device can also be reduced.
[0034] It should be noted that the display device can be a display, which may include a shell 500 and a display panel (not shown in the figure) arranged on the side of the shell 500. The display panel can be any suitable panel, for example, it can be an LED (light emitting diode) or LCD (liquid crystal display) structure, which will not be repeated here. The display driver chip 100 and the graphics card chip 210 of the graphics card module 200 are arranged inside the shell 500. The graphics card chip 210 is signal-connected to the display driver chip 100, and the input image signal is rendered and then transmitted to the display panel through the display driver chip 100 for display.
[0035] like Figure 1 As shown, in some embodiments, the display device further includes a first circuit board and a second circuit board 220, the display driver chip 100 is disposed on the first circuit board; and the graphics chip 210 is disposed on the second circuit board 220. The display device may include a first circuit board and a second circuit board 220 disposed inside the housing 500, and the graphics card module 200 may include a graphics card chip 210 and a video memory, etc. The graphics card chip 210 and the video memory may both be disposed on the first circuit board, that is, the graphics card chip 210 and the video memory may be integrated on a newly added first circuit board inside the housing 500 of the display device as in a discrete display, and the display driver chip 100 may be disposed separately on the second circuit board 220. In this configuration, the graphics card chip 210 and the display driver chip 100 are disposed separately on a circuit board, which is convenient for later maintenance and replacement.
[0036] like Figure 2 As shown, in some other embodiments, the display device may further include a third circuit board, and the display driver chip 100 and the graphics chip 210 are both disposed on the third circuit board.
[0037] The graphics card chip 210 can also share a circuit board with the display driver chip 100, that is, the graphics card chip 210 and the display driver chip 100 and other components (such as a heat dissipation module) are installed together on the same larger circuit board. The advantage of such a configuration is that it can improve integration and space utilization.
[0038] It should be noted that the data output from the host end is input into the graphics card module 200 (graphics card chip 210) through the OcuLink interface or the Thunderbolt interface, and then the graphics card chip 210 completes the image rendering, and then transmits the video signal to the display driver chip 100 through the circuit on the circuit board or the universal DP / HDMI interface, and finally the display driver chip 100 outputs the final video signal to the display panel. In addition, the two can share the input power supply, saving cost and space.
[0039] Among them, the OcuLink interface is an interface transferred from the solid-state drive slot on the computer motherboard, which is a PCIE channel. HDMI (High-Definition Multimedia Interface) and DP (DisplayPort) are two interface standards widely used today to connect monitors and other external devices. HDMI interface: HDMI is a digital interface standard that supports high-definition multimedia transmission and transmits audio and video signals at the same time; DP interface: DP is a digital video interface standard that also supports high-definition multimedia transmission. It was originally launched by VESA (Video Electronics Standards Association). The DP interface can support other types of display connections such as VGA, DVI and HDMI by using an adapter.
[0040] like Figure 3 As shown, in some other embodiments, the display driver chip 100 and the graphics chip 210 are integrally formed. The graphics card module 200 may further include a video memory, which is connected to the display driver chip 100 and the graphics chip 210 respectively.
[0041] The display driver chip 100 and the graphics chip 210 can be integrated together using a multi-chip packaging process. For example, the display driver chip 100 and the graphics chip 210 can be packaged and formed using an on-die process (chip built-in process) or a chiplet process. At this time, the graphics chip 210 and the display driver chip 100 are integrated together in the circuit board of the display device. In this way, the data output from the host end is input into the graphics chip 210 through the OcuLink interface or the Thunderbolt interface, and then the graphics chip 210 completes the image rendering. Since the graphics chip 210 is integrated with the display driver chip 100, it is no longer necessary to pass the signal to the display driver chip 100 through the above-mentioned interface or line, that is, there is no need to transmit the video signal between the two modules. The integrated module can directly drive the data in the video memory (such as the Frame Buffer) to the display panel, and there is no need to package and unpack the video signal, etc., which reduces the time consumption required for transmission and helps to reduce display delay.
[0042] Among them, the chiplet process is to split the functions of a single SOC chip (system-on-chip) into many small chips (chiplet dies), and then use advanced packaging technology (2.5D / 3D / Fanout, etc.) to reassemble them into a large and complex system in one package, thereby reducing the total cost of the chip.
[0043] like Figure 4 As shown, in other embodiments, the graphics card module 200 further includes a graphics card dock 230, and the graphics card chip 210 is detachably mounted on the graphics card dock 230; the graphics card dock 230 is in communication with the display driver chip 100. A graphics card dock 230 can be built into the housing 500 for mounting the graphics card chip 210, wherein the graphics card dock 230 can be in communication with the display driver chip 100 via a universal DP / HDMI interface. That is, except for the graphics card dock 230 and the graphics card chip 210, other components of the display device are consistent with the display device in the related art.
[0044] The data output from the host side can be input into the graphics dock 230 and the graphics chip 210 installed in the graphics dock 230 through the OcuLink interface or the Thunderbolt interface, and then the graphics chip 210 completes the image rendering. At this time, the graphics chip 210 needs to transmit the signal to the display driver chip 100 through the universal DP / HDMI interface, and finally the display driver chip 100 outputs the final video signal to the display panel. It is understandable that the power supply of the graphics dock 230 can be built-in or external. In this embodiment, since the graphics chip 210 is detachably installed in the graphics dock 230, the user can replace different models of graphics cards, which is convenient for the user to upgrade the graphics card.
[0045] It should be noted that a mounting hole may be provided on the shell 500 corresponding to the socket of the graphics card dock 230 for mounting the graphics card chip 210 , so that the graphics card chip 210 may be plugged in and out without the need to disassemble the shell 500 , thereby facilitating the user to replace the graphics card chip 210 .
[0046] In order to supply power to the display driver chip 100, the graphics chip 210 and the display panel, the display device further includes a power module 300, and a power interface 310 of the power module 300 is respectively connected to the display driver chip 100 and the graphics module 200. In general, the display device generally has its own power module, which can be used to supply power to the display driver chip 100 and the graphics chip 210. For example, a power interface 310 for power supply can be provided on the housing 500, which is used to connect to an external power source for power supply.
[0047] It should be noted that the display driver chip 100 and the graphics card module 200 can share a power module 300 to save cost and space. Of course, a power module 300 can also be configured for each of them. For example, the power module 300 can include a first power interface 311 for connecting to the display module and a second power interface 312 electrically connected to the display driver chip 100, so as to provide power guarantee to the graphics card chip 210 and the display driver chip 100 respectively.
[0048] In order to ensure the connection between the display device and the host, in some embodiments, the display device may include a first signal interface 410 connected to the graphics card module 200 signal, wherein the first signal interface 410 can be configured as an OcuLink interface or a Thunderbolt interface.
[0049] In the related art, the high-bandwidth data communication between the host controller (CPU) and the graphics chip 210 is usually completed by the PCIE bus (English: peripheral component interconnect express, a high-speed serial computer expansion bus standard). According to such requirements, the PCI-SIG organization has formulated the OcuLink standard to provide an interface for high-speed connection with an external graphics card by externalizing the PCIE interface, which can usually reach the bandwidth of PCIE3.0×4 or PCIE4.0×4, which can meet the needs of most current mid-range graphics cards. In some external graphics card solutions, there is also a solution for connecting the CPU and GPU through the Thunderbolt interface, and the controller of the Thunderbolt interface also communicates with the CPU through the PCIE bus, but this usually requires an additional control chip and may be bandwidth-limited. Therefore, in order to solve the connection problem between the display device and the host disclosed in the present invention, the graphics card module disclosed in the present invention, that is, the graphics card chip 210 is connected to the host through the OcuLink interface or the Thunderbolt interface to meet the connection problem between the display device and the host.
[0050] In some embodiments, the display device may further include a second signal interface 420 connected to the display driver chip 100. The second signal interface 420 is configured as a DP / HDMI interface. For the display device of the present disclosure, since the user may only need to input a video signal without rendering the image, the display device of the present disclosure retains the second signal interface 420 for the pure display mode, which is used to directly connect to the display driver chip 100.
[0051] The display device disclosed in the present invention combines a graphics card module and a display into an integrated product. First of all, in most cases, current independent display users directly connect to an external display screen (referred to as an external screen); and at the same time, the external screen generally has its own power supply module, so the installation disclosed in the present invention is not technically constrained. The graphics card module 200 can be combined with the display driver chip 100 of the display to improve the integration through a solution similar to a notebook motherboard; or the graphics card dock 230 can be directly integrated into the display device (display) to facilitate users to replace the graphics card. Since the graphics card module of this proposal can be directly connected to the display panel in the device, this solution can also reduce the consumption of video (such as HDMI or DP) cables required to connect the display.
[0052] The technical solution disclosed in the present invention improves the integration of computer accessories, can reduce the desktop space occupied, reduce the delay of video signal transmission, and facilitate the application of external graphics card solutions; at the same time, it creates conditions for possible new technologies in the future, such as the integration of display driver chips and GPU chips. At the same time, in some of the above implementations, the ability to input signals from the host through DP / HDMI and display is retained to realize the functions of traditional displays and meet the needs of users.
[0053] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0055] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
