Hyphy (Sample Analog Processing) demonstrates an analog signal transmission technology for display panels at Display Week 2026. The system uses an FPGA-based platform to convert video signals from a laptop into analog transmission, which is then sent across multiple PCB assemblies to a timing controller board. This approach replicates the signal path found in television systems while enabling higher bit-depth transmission than current digital interfaces allow. Hyphy’s SAP system represents a fundamental shift from digital to analog display interconnect at the panel level. The core innovation addresses a fundamental limitation in current television architectures where the TV subsystem can only transmit a maximum of 10-bit data to display drivers, even when processors internally handle 12-bit or higher bit-depth processing for gamma curve adjustment. By implementing analog transmission of pixel samples across single wire pairs, Hyphy enables 12-bit, 14-bit, or even 16-bit input signals to reach display drivers without compression. The system achieves uncompressed bit-for-bit transmission at data rates exceeding four gigabits per second across a single wire pair, a rate technically impossible with current digital approaches without compression. This analog method also provides benefits including reduced EMI, lower power consumption, and simpler TV assembly processes, potentially reducing overall system cost compared to fully digital implementations at these bandwidth levels. The technology is designed to integrate as a transmitter within existing SOC (System on Chip) architectures from vendors like MediaTek or Realtek, replacing current display driver ICs and timing controllers. Hyphy’s solution is compatible with COF (Chip on Film) mounting technology used in current 4K panels, and scales effectively to 8K and 16K resolution displays with high refresh rates. The company targets gaming applications where fast refresh rates and deep color are increasingly important, while noting that existing streaming content remains compatible with the higher bit-depth capability.
