sixthhd hd-1 mystery chip
« on: October 21, 2019, 05:14:27 pm »
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.


often times... there are other approaches which are kinda crappy until you put them in the context of parallel machines

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/
