STMicroelectronics (distributed in Australia
by Arrow Electronics) and LG Display have announced they submitted to
the VESA (Video Electronics Standards Association) TV Panel Task Grouptheir proposed
iDP (Internal DisplayPort) interface standard aimed at replacing the current
LVDS (Low Voltage Differential Signaling) standard.
Based on DisplayPort, an open and
royalty-free VESA digital-display interface standard that enables
high-bandwidth audio and video-signal transmission,
the iDP standard is targeted for the connection between a TV-controller SoC (system-on-a-chip)
and an LCD-panel timing controller within a TV chassis. With a link operating
at 3.24 Gbps per differential pair, only 17 signals (eight differential pairs
and one hot plug detect signal) are needed to transport Full HD 240Hz at 10 bits per colour over the iDP
link, substantially fewer than the 96 signals required for a conventional LVDS
link.
The companies said that, to enable more realistic
animation, graphics and 3-D video and better overall picture quality, LCD TVs
are advancing toward higher refresh rates thus 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, accelerate market adoption and drive innovation in the consumer
electronics industry.
