: Compared to older standards like LVDS, eDP 1.4 uses fewer wires (as few as 5 signals total), which allows for thinner laptop hinges and reduced electromagnetic interference (EMI). It allows the high-bandwidth data to be split
This feature supports "Segmented Panel Display" architectures. It allows the high-bandwidth data to be split across multiple links, enabling ultra-high-resolution displays (like 4K and 8K) without requiring a massive, power-hungry single controller.
Review the DisplayPort Standard Version 1.4a public overview (VESA.org). It covers lane counts, encoding (8b/10b + DSC), and connector types.
eDP 1.4 supports DSC 1.1, which enables visually lossless compression. This allows for higher resolutions (like 4K and 5K) over fewer wires.
