Adafruit.com is selling TFT-LCD modules that comes with an NTSC/PAL driver board. The product specification page includes a link to the original manufacturer´s datasheet/specifications for the TFT itself (without the NTSC/PAL driver board). As the displays sold at Adafruit.com are unecessarily (i think) expensive, and I want to buy one at eBay instead, but I can't find any NTSC/PAL driver board for the 24-bit parallel RGB interface. I found a board that lets you connect a HDMI-transmitting device to a LVDS TFT-LCD, but those LVDS display often cost more than I plan to spend on a TFT.
What kind of board/chip should I be looking for if I want to connect a HDMI/VGA/NTSC/PAL device to a 24-bit parallel TFT-LCD?
