Friendly greetings ! i bought a 7" screen branded "Koolertron". Since it's for an FPGA project i, teared it down but found a weird chip with the model erased and rewritten : "SIXTHHD HD-1" My google-fu found this japanese video I don't speak japanese :( But thanks to him, it pointed to a Realtek RTD2660. Well, the photo and spec he got was a RTD2660 but he ended up witht he same weird chip as me. The screen i bought, look like the same board, do not mention any chipset at all. i can only assume it's a RTD2660. This is the datasheet i found : http://aitendo3.sakura.ne.jp/aitendo_data/product_img/lcd_controller/Xs/RTD2660.jsp.pdf marked CONFIDENTIAL FOR GMI ONLY. Apparently it support a whole bunch of stuff (eg : downscaling 1920x1440 input to the 1024x600 output) Anyone have experience with this mystery chip ? Can i assume it's really a RTD2660 ? Any way to confirm ? It even have a 8051 MCU with 256KB of flash ^^ (for the OSD i assume) thank you. PS : we can see on the full photography there is a little bit of a non-erased logo than can possibly be part of the realtek logo. |

You can check the pinout. I suspect RTD2660 or 2662 is correct, and you can find (Russian only, unfortunately) a firmware project for them: http://openrtd2662.ru/ |
