Hi all,
I have not gotten my Retrostones yet. But I have already been looking in to possible replacements for the screen.
The Retrostone uses the LQ035NC11. 3.5in, 320x240, 4:3 aspect, 54pin.
The LCD can be fed an RGB24bit signal, but the RetroStone is taking an analog composite signal and converting it using an AMT630 Video Display Controller IC (I think).
From the videos I've seen, I think the poor quality is mostly from the analog composite feed and only partly from the 320x240 screen.
Trying to feed the LQ035NC11 the HDMI singnal would be tricky because of the 54pin connector.
It is not easy to find a 3.5in, 4:3 LCD screen. I have a few ideas, please let me know what you all think.
It may be easiest to replace the LQ035NC11 with a better screen and feed it the HDMI feed. I was looking at this LCD:
40 pin Transflective IPS, 3.5 inch, 640x480 lcd, 4:3 aspect.

And I was thinking of using an HDMI to 40pin converter to feed it. Like this one:
TFP401 HDMI/DVI Decoder to 40-Pin TTL Breakout

Adafruit also makes some very small HDMI right angle adapters and 40pin extension ribbon cables.
So I was thinking of taking the HDMI port of the Retrostone and feeding the new 40pin LCD. (no more external HDMI)
This will be tricky with the limited room. I am not sure the new display will fit. Once I have mine I will be able to measure better.
LQ035NC11 dimensions: 76.9(W)x63.9(H)
New LCD dimensions: 85(W)x68(H)
Anyone think this is doable?
Thanks,
Brandon
