High-End Computer DIY Enthusiasts’ Demand for High-Definition Video Signal Integrated Slip Rings

With the continuous development of the computer DIY market, some high-end DIY enthusiasts are no longer satisfied with simple configurations and assembly. They are increasingly pursuing higher levels of customization and innovation. For these enthusiasts, in addition to conventional hardware components, they are gradually incorporating slip rings—originally a component closely related to industrial applications—into their personal computer builds to achieve more unique functionalities, particularly in high-definition signal transmission and multimedia capabilities.

For DIY enthusiasts seeking ultimate performance and innovation, a new challenge has emerged: how to transmit high-definition multimedia signals seamlessly and integrate them into computer systems. In this process, slip rings, which can transmit both power and signals, have gradually become essential tools for these enthusiasts to achieve creative features. Among them, JINPAT’ HDMI and DisplayPort (DP) signal-integrated slip rings have been developed specifically to meet this demand. These products not only play a vital role in industrial robot vision systems and VR devices but have also become the choice of high-end computer DIY enthusiasts, helping them create unique hardware devices.

When it comes to high-definition signal transmission, particularly HDMI and DP signals, the transmission distance and signal quality requirements are exceptionally high. Therefore, in response to the needs of DIY enthusiasts, JINPAT has designed a compact integrated slip ring. These slip rings are usually designed to be small in size, allowing them to be used in compact DIY devices. Additionally, the length of the wires on both ends of the slip ring must meet certain limitations to ensure stable signal transmission.

Take the example of an HDMI and USB integrated slip ring custom-made by JINPAT for an overseas customer, model LPM-30B-HD01-U2-0203. This slip ring has a diameter of only 16mm and a length of 37mm, supporting the rotational transmission of 1 HDMI signal and 1 USB 2.0 signal, with a maximum capability of transmitting 1080P@60fps video signals. This slip ring is particularly suitable for devices based on NVIDIA graphics cards, as it effectively supports HDMI signal output. However, for some enthusiasts using AMD graphics cards, HDMI signals are not sufficient, as the video output interface for AMD graphics cards is DP. Therefore, JINPAT has also developed HDMI and DP integrated slip rings designed specifically for DP interfaces.

Compared to HDMI signals, the transmission requirements for DP signals are more complex. To support DisplayPort signals, the slip ring needs more circuits to handle the signal, making the manufacturing difficulty and technical requirements for DP signal integrated slip rings higher. The latest model from JINPAT, LPC-12T-0202-01U2-DP, has been developed to meet this demand. Similar to the LPM-30B-HD01-U2-0203, this slip ring supports USB 2.0 signal and high-definition video signal transmission. The key difference lies in the additional circuits required for DP signal stability, increasing the slip ring’s length to 74mm. The complexity of DP signals is reflected not only in the added circuits but also in the impedance matching of the signals, making the manufacturing process more technically challenging.

As computer DIY enthusiasts’ demands for hardware performance and customization continue to rise, slip rings—an innovative component—are gradually becoming part of this field. Whether for HDMI signal integrated slip rings or custom-designed slip rings for DisplayPort signals, JINPAT’ high-quality products can meet enthusiasts’ stringent requirements for high-definition video signal transmission, helping them build more advanced and unique DIY devices. With continuous technological advancement, the application prospects for slip rings in the computer DIY field will become even broader in the future.
