Title: TE LCD pinout?
Post by: wilykat on June 25, 2015, 08:29:42 AM

Anyone know of the LCD pinout?  Other LCD systems (Gameboy, Lynx, and Game Gear) had 20 or 30 lines between the board and the LCD, which suggest the LCD were directly controlled.  TE cable however is only 8 lines total.

Does it means TE LCD uses analog video such as RGB?

There is a Mod/Repair section filled with this kind of info.

No wonder I didn't find it.  Thanks!!  If only 3.5" LCD with RGB input were easy to find.  Maybe I'll fire up my old oscilloscope and see if there is composite to RGB separator on LCD and tap there?  Inverted sync seems odd though, I wonder if it can be in-inverted using something like 7404 or 4069 or if the composite sync is analog rather than digital?

its TTL inverted sync so yes a logic inverter works
the 3.5LCD board goes from composite to digital RGB, not analog so that wont work
