New interface standard promises enhanced performance of LCD TVs

STMicroelectronics (Lexington, MA) in alliance with LG Display (Seoul, Korea) announced submission of their proposed iDP (Internal DisplayPort) interface standard aimed at replacing the current LVDS (Low Voltage Differential Signaling) standard to the VESA (Video Electronics Standards Association) TV Panel Task Group

As today’s LCD TVs are rapidly advancing toward higher refresh rates in order to support more realistic animation, picture quality, and 3-D video, they are creating the need for a new high-speed panel-interface standard. The proposed iDP standard was developed as an open and royalty-free industry standard to address this market requirement and drive innovation in the consumer electronics industry.

iDP is based on DisplayPort, an open and royalty-free VESA digital-display interface standard. The DisplayPort interface allows high-bandwidth audio and video signal transmission by using an advance digital protocol.

Both companies currently plan to promote and demonstrate iDP technology in the market and to establish a wider cooperation on the definition and development of common technologies and innovative solutions to support the next generation of high-refresh-rate LCD panels.

As early as this month, ST plans to sample a series of products which supports the deployment of iDP. Products will include: LVDS to iDP and iDP to LVDS bridge ICs, 240-Hz video enhancement IC with iDP output, and 120-Hz TV System-On-Chip with iDP output.
