Abstract

High-definition display devices supply performance required high resolution, high-speed data transmission, and stable power. This paper proposes a design method for flexible printed circuit boards (FPCBs) based on LCOS chips. By incorporating high-speed differential transmission links, enhanced-power traces, and integrated heat dissipation structures, the design achieves multi-channel and high-speed data transmission and refresh rates while reducing transmission loss. After test and comparative analysis show which is for an FPCB that supporting 18 Gbps high-speed data transmission and a 180 Hz refresh rate, the optimized design improves heat dissipation efficiency by 57%. It provides technical support for high-end display devices such as high-definition projectors.
