In modern laptop display systems, the screen cable plays a crucial role in carrying high-definition signals and ensuring image quality. With the continuous advancement of high resolution, narrow bezels, and slimming trends, traditional FFC or LVDS cables have gradually been replaced by ultra-fine coaxial cables (micro coaxial cable). Understanding the core parameters of the screen cable is of great importance for engineering selection and product reliability.
Resolution and screen line requirements
As the resolution of notebook screens develops from 2K, 4K to higher levels, the amount of data transmission increases significantly. The screen cable needs to have high signal integrity and good anti-interference ability. The extremely thin coaxial cable bundle, with its independent shielding structure and low signal loss, can effectively support the stable display of high-resolution images, providing reliable protection for image transmission.
Bandwidth and Signal Integrity
Bandwidth is a core indicator of the transmission capability of screen cables. For example, a 4K 60Hz display often requires bandwidth exceeding 10Gbps, which demands that cables maintain low attenuation and low jitter at high frequencies. Micro coaxial cable achieves high-speed data transmission within a limited space through precise impedance control and small diameter design, ensuring signal integrity and image stability.
Three, Interface and Compatibility
The notebook screen interface mainly includes eDP and MIPI DSI. eDP is more suitable for large-sized high-resolution screens, while MIPI is often used for ultra-thin or high refresh rate models. Different interfaces have different requirements for wire harness structure and impedance characteristics. Extremely thin coaxial cable harnesses are flexible and easy to customize, capable of adapting to various interface standards, and meeting different notebook design requirements.
The core of the notebook screen cable lies in the matching of resolution, bandwidth, and interface. With the continuous increase in display requirements, ultra-thin coaxial cables will play an even more important role in future notebook designs. Choosing the appropriate micro coaxial cable can not only ensure image quality and performance but also take into account the slim design and product reliability.
