VESA issued the new Internal DisplayPort (iDP) interface standard for inside-the-box connectivity within flat panel TVs. The standard is designed to replace LVDS (Low Voltage Differential Signaling) with a simpler and higher-performing connectivity technology based on the widely adopted VESA DisplayPort standard. The VESA iDP standard addresses the connection between a TV controller SOC (System-on-a-Chip) and a TV panel Timing Controller (TCON) within a TV chassis. Only 17 signals – eight differential pairs and one Hot Plug Detect (HPD) signal – are needed to transport Full HD 240Hz at 10 bits per color over the iDP link, reducing cost and manufacturing complexity compared to the LVDS 96-signal requirement.

This is a scalable standard, allowing for support of future design needs. Other iDP advantages include elimination of the many LVDS printed circuit board traces and device pins which result in reduced system form factor and cost, and less shielding requirement due to reduced EMI. Similar to the existing VESA eDP (Embedded DisplayPort) interface standard used within Notebooks and other PC devices with internal displays, iDP is designed around the special needs of flat panel television displays and provides specific optimizations for internal flat panel TV applications.
