In high-resolution displays and mobile terminals, MIPI DSI has become the mainstream display transmission method. However, with the continuous increase in speed, problems such as signal attenuation, interference, and impedance instability have become increasingly evident. To ensure the stability of high-speed transmission, ultra-fine coaxial cable bundles are gradually becoming an ideal choice.
The main challenges of DSI high-speed transmission
DSI usually needs to complete data transmission at rates of several Gbps. Under high-frequency conditions, signals are affected by loss, reflection, and electromagnetic interference, and the internal space of devices is limited with complex routing. Standard ribbon cables are difficult to meet the needs of high-speed transmission in this environment, so a more reliable structure is required to ensure stability.
The performance advantages of ultra-fine coaxial beam
The ultra-fine coaxial cable bundle features an independent channel design, which can maintain stable signal quality at high frequencies, reduce bit errors and crosstalk. Its shielding structure effectively suppresses external interference and improves the system's noise immunity. At the same time, the cable bundle is soft and thin, making it easy to route in confined spaces. Precise impedance control can also reduce reflections and improve overall transmission quality, suitable for 4K, 8K and other high-definition display systems.
Key points to be aware of in DSI application
High-speed transmission requires consistent impedance, short wiring as much as possible, and avoid excessive bending. Good shielding and grounding design can further reduce interference. Materials should be selected with low loss and high reliability to adapt to complex environments in mobile devices, vehicle-mounted displays, and folding devices.
Extremely fine coaxial cables, with their high-frequency performance, anti-interference capability, flexible structure, and stable impedance, have become an important solution for DSI high-speed transmission. As display bandwidth continues to increase, such cables will play a crucial role in more high-end display devices.
