Interesting info in T68 R5D007 FW

This should probably go in a tech forum, but the latest R5D007 FW has some interesting params:

resolution=65 50;
colours=08 03 03 02;

You'll realise that this is part of the LCD display block. The 200109110 graphics core hasn't changed since the T68m, but the revision is now 102096/1 R4A. The device uses the i2c interface. Anyone have links, tech specs or part numbers for the graphics/lcd sub-systems of the T68? (No info in the FAQ/forum search/Google, etc)

I wonder what would happen if we change the res values (hex) or bit-depth to > 8-bit...? Anyone experimented thus far? It might be usefull to have detailed specs prior to testing...

Interesting, I've been browsing through the firmware files a bit too -- might be useful to find some hidden features =P

Has anyone tried modifying the firmware and uploading it to a phone yet? I think it would be cool if we could translplant Tetris from the t68 to the new firmwares

I'd forgotten that I already had the white papers from ericsson on the t68/t68i/t300/p900...

Not enough hardware detail in these either, but they do state max lcd size, 70Hz refresh rate, 12MHz AVR, & confirm 8k video ram. No info as to whether this is UMA or discrete. I assume discrete, which means that 101x80x1=8k. The 3/3/2 RGB setup means reduced blue color palette. There's not enough VRAM to try 9-bit for 512 colors 101x80 res, but it may be possible to try 9-bit @ 90x80 if the video controller/software is flexible enough...

Edit: This EETimes story has some tech details & circuit components/topology pic:

very informative indeed. but for the non-tech savvy... i think all they can say about this is... "uhhhh... DUH?" thanks for the info guys!

Um, yeah...

The closest LCD panel that Seiko/Epson manufactures is a 128x128 pixel device with 64k RAM. Perhaps SE has an OEM unit made...? Otherwise, there may be opportunities yet...
