However, as the market drives DTV price down while
requiring better picture quality, it needs to optimize DTV
system as a total system instead of optimizing panel and its
electronics system separately. To reduce the overall system
cost, DTV manufacturers try to integrate electronics part of
flat panel, such as inverter and power board, timing controller,
etc., into DTV system board, which is called backward
integration. Some FPD manufacturers are trying to integrate
DTV electronics board into panel’s timing controller board,
which is called forward integration. When the forward
integration is combined with two-chip solution where picture
quality is implemented in a separate chip, FPD could
encapsulate picture quality issues into its panel. This allows
companies with limited experience to assemble DTVs as if
the PC is assembled. The 70” LCD TV announced at 2007
SID by Samsung [7] would be an example of forward
integration. As shown Fig.4, it was claimed that by
integrating motion estimation & motion compensated frame
rate up-conversion block (ME/MC) into the timing controller
(T-con) board, the company can save extra LVDS cable and
reduce electro-magnetic interference (EMI) as well. It gives
further optimization room where two memories used for each
block, ME/MC and T-con, can be shared by integrating
ME/MD and T-con in a single chip.
