iDP (Internal DisplayPort) Interface Standard Proposed by STMicroelectronics and LG Display

LVDS to iDP: The current internal interface standard on LCDs is LVDS (Low Voltage Differential Signaling) but STMicroelectronics and LG Display want it to change to iDP (Internal DisplayPort) and have submitted their proposal to the VESA (Video Electronics Standard Association) TV Panel Task Group.

High Bandwidth & Simpler: iDP is based on DisplayPort that enables high-bandwidth audio and video signal transmission. The iDP standard would be used to connect a TV-controller SoC (System-on-a-Chip) and an LCD panel TCON (timing controller). The iDP connection would require only 17 signals (eight differential pairs and one hot plug detect signal) to transport 10-bit Full HD at 240Hz using a 3.24Gbps per differential pair link. A conventional LVDS link would require 96 signals. By using iDP manufacturing the cable interconnect would be drastically simplified and theoretically reduce defects.

3D Both STMicroelectronics and LG Display suggested the shift to iDP is necessary for LCD TV panels with higher frequencies required for high-end graphics and 3D. The iDP standard proposal is open and royalty-free.
