Description

Technical Field

[0001] This utility model relates to the field of interface circuits, and more particularly to a data transmission interface circuit, motherboard, and display device compatible with multiple resolutions. Background Technology

[0002] With the development of display technology, the resolution and refresh rate of LCD screens are constantly increasing. Currently, LCD screens generally use the Video-by-One (VBO) protocol to receive data. LCD screens with different resolutions and refresh rates need to receive data with different bandwidths, so they need to use VBO sockets of different sizes.

[0003] Because the VBO interface requires a high-speed interface to transmit video stream data, and high-speed interface resources are scarce for common processing chips, and designing, drawing, debugging, and developing different circuit boards for different LCD displays is not only costly, but also requires a longer design and development cycle, so it is difficult for a single circuit to be compatible with displays of multiple resolutions. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a data transmission interface circuit, motherboard and display device that are compatible with multiple resolutions, so that one interface circuit can be compatible with multiple resolution displays.

[0011] Optionally, solder resist is provided on the pads of the fourth material device to make the multi-resolution compatible data transmission interface circuit compatible with the first resolution.

[0012] Optionally, when the first resolution is 8K@60Hz, the number of printed circuit boards is 2.

[0013] This utility model also proposes a motherboard, including the multi-resolution compatible data transmission interface circuit described above.

[0027] With the development of display technology, the resolution and refresh rate of LCD screens are constantly increasing. Currently, LCD screens generally use the Video-by-One (VBO) protocol to receive data. LCD screens with different resolutions and refresh rates need to receive data with different bandwidths, so they need to use VBO sockets of different sizes.

[0028] Because the VBO interface requires a high-speed interface to transmit video stream data, and high-speed interface resources are scarce for common processing chips, and designing, drawing, debugging, and developing different circuit boards for different LCD displays is not only costly, but also requires a longer design and development cycle, so it is difficult for a single circuit to be compatible with displays of multiple resolutions.

[0029] To address the aforementioned problems, this invention proposes a data transmission interface circuit compatible with multiple resolutions.

[0030] Reference Figure 1 In one embodiment, the multi-resolution compatible data transmission interface circuit includes: First material / device 101; Second material device 102; Third material device 103; Fourth material / device 104; A printed circuit board 100 is provided with pads for soldering the first material device 101, the second material device 102, the third material device 103 and the fourth material device 104; The first material device 101 is used to make the multi-resolution compatible data transmission interface circuit compatible with the first resolution; The second material device 102 and the fourth material device 104 are used to make the multi-resolution compatible data transmission interface circuit compatible with the second resolution; The second material device 102, the third material device 103, and the fourth material device 104 are used to make the multi-resolution compatible data transmission interface circuit compatible with the third resolution.

[0031] In this embodiment, the components on the printed circuit board 100 can be various electronic components and materials used to build the circuit, including but not limited to connectors, terminals, solder, copper plating, resistors, capacitors, diodes, and transistors. The pads (not shown in the figure) provide a conductive path between the pins of electronic components and the lines on the printed circuit board 100, allowing current to flow normally between different components and circuits, ensuring the stable electrical performance of the entire circuit system on the printed circuit board 100. Through the soldering process, different components are fixed to the pads of the printed circuit board 100, ensuring that the components will not loosen or fall off due to external forces such as vibration or impact during use, thereby maintaining the physical structural integrity of the circuit board. This solution allows different component materials to be soldered onto the pads of the printed circuit board 100, enabling the interface circuit to be compatible with multiple different resolutions. For example, a 4K@60Hz display requires one 51-pin VBO interface socket to transmit 8 channels of VBO data; a 4K@120Hz display requires one 51-pin and one 41-pin VBO interface socket to transmit 8 channels of VBO data respectively, for a total of 16 channels of VBO data; an 8K@60Hz display requires two 51-pin VBO interface sockets to transmit 16 channels of VBO data respectively, and an additional 12-pin socket to transmit other control signals. The display resolutions in practical applications include, but are not limited to, the three mentioned above. Thus, different VBO interface sockets can represent the corresponding first component material 101, second component material 102, third component material 103, and fourth component material 104, and the specific component corresponding to the component material can be selected and set according to the required compatible resolution; resistors can also be set as component materials to adjust the impedance of the differential signal link.

[0032] In practical applications, four component pads can be designed on the printed circuit board 100. Then, corresponding components can be placed on the pads of the printed circuit board 100 according to the resolution of the LCD display to be connected. Furthermore, if needed by the user, the components on the printed circuit board 100 can be disassembled and replaced to achieve compatibility with other resolutions. Thus, this multi-resolution compatible data transmission interface circuit achieves compatibility with a variety of different resolutions.

[0033] This utility model's technical solution uses a first material device 101, a second material device 102, a third material device 103, a fourth material device 104, and a printed circuit board 100 to construct a multi-resolution compatible data transmission interface circuit. Furthermore, placing the first material device 101 on the printed circuit board 100 allows the multi-resolution compatible data transmission interface circuit to be compatible with a first resolution; placing the second material device 102 and the fourth material device 104 on the printed circuit board 100 allows the multi-resolution compatible data transmission interface circuit to be compatible with a second resolution; and placing the second material device 102, the third material device 103, and the fourth material device 104 on the printed circuit board 100 allows the multi-resolution compatible data transmission interface circuit to be compatible with a third resolution. Thus, this solution's multi-resolution compatible data transmission interface circuit can achieve compatibility with multiple resolution LCD screens on the same printed circuit board 100 design by placing different material devices on the printed circuit board 100 to correspond to different resolutions, thereby shortening the development cycle and reducing debugging costs.

[0034] In one embodiment, the first material device 101 and the second material device 102 are 51-pin VBO sockets, the third material device 103 is a 41-pin VBO socket, and the fourth material device 104 is a resistor with a resistance of 0.

[0035] Furthermore, the first resolution is 8K@60Hz, the second resolution is 4K@60Hz, and the third resolution is 4K@120Hz.

[0036] In this embodiment, when only a 51-pin VBO is provided on the printed circuit board 100, the multi-resolution compatible data transmission interface circuit can be compatible with an 8K@60Hz LCD screen. For details, please refer to... Figure 2 When a 51-pin VBO connector and a zero-resistance resistor are set on the printed circuit board 100, the multi-resolution compatible data transmission interface circuit can be compatible with LCD screens with a resolution of 4K@60Hz. For details, please refer to... Figure 3When a 51-pin VBO connector, a 41-pin VBO connector, and a resistor with zero resistance are provided on the printed circuit board 100, the multi-resolution compatible data transmission interface circuit can be compatible with an LCD screen with a resolution of 4K@120Hz. For details, please refer to [reference needed]. Figure 4 Understandably, since the pinout definitions of the 51-pin connector for 4K@60Hz and the 51-pin connector for 4K@120Hz are compatible, the same 51-pin VBO connector can be used for both 4K@60Hz and 4K@120Hz resolution printed circuit boards 100. Furthermore, this design is specifically for the VBO protocol on the printed circuit board 100, therefore, the components used are VBO connectors and resistors with different pinouts.

[0037] In one embodiment, the fourth material device 104 is a 0-ohm resistor array.

[0038] In this embodiment, the fourth material device 104 uses a 0-ohm resistor array, which makes the differential signal link impedance more consistent, thereby achieving better signal transmission performance. Furthermore, the resistor array integrates multiple resistors into a single package, reducing the area occupied on the printed circuit board 100; multiple signals can also be connected in parallel through a single resistor array, reducing routing complexity and minimizing crosstalk.

[0039] In one embodiment, the first material device 101 is a 51-pin shielded VBO socket or a 51-pin unshielded VBO socket.

[0040] In this embodiment, because only a 51-pin VBO is provided on the printed circuit board 100, the compatible resolution is 8K@60Hz. At 8K@60Hz resolution, the amount of signal data transmitted is large, and using a 51-pin shielded VBO connector can improve signal transmission quality. If the user has high requirements for signal quality, a 51-pin shielded VBO connector can be used as the first material device 101. In practical applications, a 51-pin unshielded VBO connector can also complete signal data transmission. Therefore, in practical applications, the user can choose either a shielded or unshielded VBO connector as the first material device 101 according to the actual situation and specific needs. The shielding material of the shielded VBO can be metal, such as iron or copper.

[0041] In one embodiment, the pads of the first material device 101 are overlapped with the pads of the fourth material device 104.

[0042] Furthermore, solder resist is provided on the pads of the fourth material device 104 to make the multi-resolution compatible data transmission interface circuit compatible with the first resolution.

[0043] In this embodiment, when compatible with an 8K@60Hz LCD screen, only the first component 101, i.e., a 51-pin VBO connector, is provided on the printed circuit board 100 to provide 16 channels for transmitting video stream data to the 8K@60Hz LCD screen. At this time, the fourth component 104 is not provided on the printed circuit board 100, and the first component 101 can be disconnected from the second and third components 102 and 103. It is understood that due to the significant signal reflection problem of high-speed signals, the pads corresponding to the fourth component 104 need to be placed close to the pads corresponding to the first component 101, such as overlapping, to minimize signal reflection. Since the fourth component 104 is not used at this time, the pads of the fourth component 104 also need to be covered with solder resist during the manufacturing of the printed circuit board 100 to prevent the casing of the first component 101 from contacting the pads of the fourth component 104 and affecting the signal transmission quality.

[0044] In one embodiment, when the first resolution is 8K@60Hz, the number of printed circuit boards 100 is 2.

[0045] It should be noted that a 4K@60Hz LCD screen requires 8 channels of signal to transmit video stream data, a 4K@120Hz LCD screen requires 16 channels, and an 8K@60Hz LCD screen requires 32 channels. However, a single printed circuit board 100 forming a multi-resolution compatible data transmission interface circuit is insufficient to handle 8K@60Hz data. Therefore, to conserve the number of high-speed signal interfaces, a total of 16 channels are used to transmit video stream data in the VBO protocol. For the 8K@60Hz LCD screen, a multi-resolution compatible data transmission interface circuit consisting of two identical printed circuit boards 100 is used to complete the data processing.

[0046] This utility model also proposes a motherboard.

The motherboard can be a development board for researching and developing circuits. It is understood that since the motherboard of this invention uses the aforementioned multi-resolution compatible data transmission interface circuit, the embodiments of the motherboard of this invention include all the technical solutions of all embodiments of the aforementioned multi-resolution compatible data transmission interface circuit, and the achieved technical effects are completely the same, and will not be repeated here.

[0049] In one embodiment, the display device includes the motherboard described above. It is understood that since the display device of this invention uses the aforementioned motherboard, the embodiments of the display device of this invention include all the technical solutions of all the embodiments of the aforementioned motherboard, and the achieved technical effects are completely the same, and will not be repeated here.
