Have you seen this I’ve asked for a data sheet. |

I’ve heard of Pixel Qi’s screens before, didn’t know that they’d started shipping though. What have you got planned for such a screen? Or are you just curious? |

That looks really interesting. If you have any luck getting a datasheet, Dave, I’d love to have a copy! I’ve got a nice regular TFT I was all set to interface to my IGEPv2, but this looks like it would be a much better option on the face of it. If Qi’s power stats are to be believed, it would make long battery operation a real possibility. |

I’ve got sufficient engineering skills, and sufficient DIY drive, to make a portable computer. The biggest difficulty is interfacing the screen; the second biggest difficulty is getting and interfacing a keyboard. |

There’s a data sheet here: http://cdn.makezine.com/make/pdf/pixel_qi_nantasket_spec_pub1_0.pdf Looks like it has all the interfacing details. Beagle does standard LVDS doesn’t it? Then I think it should just plug in. Pixel Qi are selling this as a drop-in replacement for a few netbooks, so I don’t think there’s anything complex about the interfacing standards.

I think you may need a TTL to LVDS converter to use it with the LCD header that’s on the BeagleBoard. There’s also talk of needing a level shifter and/or buffer to clean up the signals. Basically, if you get stuck, ask on the beagleboard google group! http://markmail.org/message/2f5426kuqy724rp2 http://groups.google.com/group/beagleboard/topics |
