With the continuous development of thecomputer DIY market, some high-end DIY enthusiasts are no longer satisfied withsimple configurations and assembly. They are increasingly pursuing higherlevels of customization and innovation. For these enthusiasts, in addition toconventional hardware components, they are gradually incorporating sliprings—originally a component closely related to industrial applications—intotheir personal computer builds to achieve more unique functionalities,particularly in high-definition signal transmission and multimediacapabilities.

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

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

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

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

As computer DIY enthusiasts’ demands forhardware performance and customization continue to rise, slip rings—aninnovative component—are gradually becoming part of this field. Whether forHDMI signal integrated slip rings or custom-designed slip rings for DisplayPortsignals, JINPAT’ high-quality products can meet enthusiasts’ stringentrequirements for high-definition video signal transmission, helping them buildmore advanced and unique DIY devices. With continuous technologicaladvancement, the application prospects for slip rings in the computer DIY fieldwill become even broader in the future.
