Compression enables thinner screen bezels and tighter hinge designs, as fewer physical copper lines need to pass from the motherboard through the hinge to the display panel.
The eDP 1.4 specification is an industry-standard interface designed to transport video and audio data from a system-on-a-chip (SoC) or GPU to a flat panel display (typically LCD or OLED) in mobile and portable devices. It builds upon the DisplayPort 1.2 architecture but adds critical features aimed at reducing power consumption and supporting higher resolution panels in thin form factors. edp 1.4 specification pdf
eDP 1.4 remains the dominant internal display standard for modern computing. It successfully bridged the gap between the need for ultra-high-resolution displays (4K/5K) and the strict power constraints of mobile battery life. By utilizing Panel Self Refresh and HBR2 data rates, it provided a robust infrastructure for the "Retina-class" display era of laptops. Compression enables thinner screen bezels and tighter hinge
