About two great LCDs...

Hi everyone. Today Ive found and dismanteled a Game Boy Advance and a Scott portable DVD player in order to get their LCDs back, and here's the result (the arduino's just there for size comparison):

Now here's the problem. I can't find any datasheet for both of them. The BGA LCD has no usable reference written on it, and the big on has one (LTA070A250A), but I cant find its datasheet. Can someone help?

well i got a PSP 1000 screen and a Eee pc 900 screen :P but i doubt they will ever work with arduino...

:P I say google then google some more... but i don't think the are of any use.

hi! i googled your referenced and found this:

hope it helped :P

Thx archembo ;) I see you're french? I am too ;)

Ive browsed the datasheet and found on page 20/35 that this LCD doesn't accept parallel/serial input but RGB...thus connection to the arduino is compromised, no?

Sassa > the EeePC's screen is a VGA display, no? VGA libraries for the arduino does exists.

Can someone help with the GBA LCD?

The greater problem with (likely) both of these LCDs is the lack of a display RAM buffer; most GLCDs in commercial devices depend on an external RAM buffer for the display, and driver circuitry to continually refresh the display from the data in the RAM. Since the ATMega doesn't have the onboard SRAM to work as display RAM, even if you were able to hook it up, you likely couldn't display much (there's also the question of whether the ATMega is fast enough to output the data at the rate needed, plus a few other issues).

The GLCDs that you can get for microcontrollers generally already have the display RAM built in, and can be updated fairly rapidly by a microcontroller (mainly because there isn't that many pixels to address, even for a full-screen refresh).

Thx for your informations cr0sh, even if these are not good news :'(
