Broken PSP

[hazzer123]

I have a broken psp and i am wondering if there is anything that i could use out of it.

Is there any chance that the screen would be useful? I have found the data sheet.

It looks complicated.

Has anyone had any experience with colour LCDs or anything similar?
Any tips?

Thanks

The gumstix guys are looking for PSP screens - maybe try posting on the gumstix mailing list - you might get someone willing to pay for it...

I know how to use a typical black/white LCD.  This I have little clue.  It seems that each pixel is ran by 8 pins of each color.  I couldn't figure out a practical application for it other than making a game system out of it or a television.  Hence why they built it for PSPs and such.  I found a way you can make a laptop (very very basic) out of a microcontroller and an LCD, but they used a 2-bit LCD.

Money is always a good thing

Hmmm... I could make a bit of money. But for such a great screen...

Does anyone think i have a chance of displaying anything on it?

From the datasheet it looks like you just stick a byte in parallel across the 8 wires for each color and then strobe the clock signal. Along with the horizontal and vertical syncs. If i was to do it, i would initially have the 8 wires for each all joined together so that the RGB value is either 0 or 255. To make things simpler.

One thing though, is that it says that there is a minimum clock frequency of 7.83 MHz. Why is that? I was gonna try and do it with a pic running at 20Mhz but it wouldnt be fast enough. Must I run it at least this fast?

put it in the front of of your computer?

What do you mean?

That's an interesting idea.  Make a circuit involving a few temperature sensors that constantly take temperature of the processor temperature and others.  Well, if you're majorly into computer like me then do it    If you have a cool computer case you could implement that in and that would be wicked.      I want one now... Well, I'd rather get one with a cool blue backlight.

Or, ummm.  You could make it display explicit messeges to people who enter your house?  Dunno, lots of possibilities.  Be creative

nanobot- you into custom pc's and overclocking? ever been at eocf?

[hazzer123]

Yeh thats a great idea but... I need to know how to get it to actually display something.

Another thing. Are there any connectors to convert the tiny FPC connector of the LCD to something more usable eg DIP?

Thanks

Yes, I love building computers and playing with hardware as much as I do building robots.  The only problem is they're many many times more expensive than robots     To a certain degree.   No I have never been to eocf.  What does it stand for?

Back on topic...

You do have the broken PSP.  The best step would be to throughly examine the insides of the PSP and perhaps see how the manufacturers put the thing together, I'm sure you can learn something from that. 

In terms of running displays, I'm not too sure.  I could create a computer program for it, I know how to do stuff like that.  Implementing something into a microchip to get it to run out of the display, I'm not too sure.  That's why I like the computer idea.  I can get a 8-bit display to work, but have never experimented into LCDs. 


I found an interesting link dealing with LCDs and computers.  Check it out.  Maybe it can at least help you with implementing the screen into something:
