Notably, the peaks of radiated emission from the TFT-LCD panel were clearly visible at 140 MHz, 210 MHz and 280 MHz, which were in the second to fourth harmonics, respectively, of the clock signal from T-CON.
As noted above, the clock signal from T-CON couples to the DC supply loop.
The noise source from T-CON interferes with the DC supply loop between the DC-to-DC converter and the source driver IC.
The radiated emission at approximately 140 MHz may be the main radiation mechanisms because DC supply loop may behave like an antenna, radiating the noise source that is coupled from the T-CON.
Our first-generation eDP T-CON was very successful.
The DP616 is a one-lane main link T-CON that supports eDP link rates up to 2.
FP-LVDS is a method to transmit signals from the T-CON to the driver, which operates on a 250 MHz high-speed clock.
This collaboration enables the two companies to provide interconnecting FP-LVDS-based source drivers and T-CONs to support hyper color managing LCD modules such as LCD TVs and monitors.
The chip is the first one on the market to integrate video decoder, scalar, deinterlacing, T-CON
(Timing Controller) and OSD (On Screen Display) functions as a completely integrated solution for small and medium size flat-panel display monitors.
