Internal DisplayPort interface from ST for 120Hz/240Hz LCD TVs

New 'bridge' chipsets are available from ST Micro for the iDP (Internal DisplayPort) standard to LVDS (Low-Voltage Differential Signalling) translation for use in 120Hz/240Hz LCD TVs.

This interface is designed for the connection between the TV-controller SoC (System-on-Chip) and a TV-panel Timing Controller within a TV chassis, iDP is an advanced technology based on DisplayPort technology.

Built using DisplayPort technology and featuring low-power design and low EMI (Electro-Magnetic Interference), these new iDP-to-LVDS bridge chipsets from ST will provide robust interoperability and cost effectiveness.

The chipset solution comprises a single-link iDP interface capable of transporting uncompressed pixel streams up to 12.96Gbps bandwidth between TV SoC and LCD panel module over four pairs of low-cost twisted wires or FFC (Flat Flexible Cable) cabling. ST's iDP transmitter and receiver devices are fully scalable, each chipset can support FHD (Full High-Definition) video (at 1080p/30-bit per pixel) at 120Hz refresh rate, two sets can support FHD-240Hz refresh rate panels.

Both the transmitter and receiver devices integrate high-speed Quad-LVDS interfaces for conversion between conventional Quad-LVDS and iDP to address transitional market needs. These products offer maximum flexibility to TV manufactures and enable seamless transition to iDP.

The new chipsets are compliant with the ST's iDP interface standard, in collaboration with LG Display, to the Video Electronics Standards Association (VESA) TV Panel Task Group.

In addition, the spread-spectrum technique, employed in conjunction with iDP's self clocking, data scrambling and inter-lane de-skewing architecture, bring additional cost savings by eliminating external EMI-reduction components.

ST's first iDP-based solution comprises an iDP transmitter and iDP receiver, the STiDP888 and STiDP880,respectively.
