  5. Hello Alex,

    Schematic will be posted after final checks in 1-2 days.

    First of all, we will sell bundles (LCD + board + cable). And only board will be available for order end of November. This is because we have huge requests for bundle and will be full time busy with this.

  6. Hi,

    Have you tested this screen and board with an android distrib?

  7. Hello adrienferre,

    It should work with any OS, because our board is just a substitution for external DVI monitor. I will try and record video with Android distrib later - just for fun.

  8. Hello!

    Dropping by again to ask about compatibility.

    I have recently acquired a WUXGA panel LC420WUE. If I have external control for the backlight and 12V for the panel, would it work with a combination of pandaboard and your board?

    Also, would it be plug@play or does it require modifications to kernel source?

    Thank you.

  9. Hello Meizirkki,

    42" panel??? Designing notebook for elephants? :)

    I checked datasheet - it should work if you use just LVDS lines from our board. Don't forget to select 8-bits VESA format in panel (pins 7 and 27). Also, try to use short LVDS cable, because we didn't met 100 Ohm LVDS impedance exactly due to physical constraints of our PCB, and for your pixel clock (75 Mhz) there could be significant reflections on long cable.

    Kernel patching is not required with new board.

  11. What is the current demand from that screen?

  12. Hello mrbabbagepresents,

    Typical current is around 200mA for logic (at 3.3V), 30mA for touchscreen controller (at 5V) and 350mA for backlight (at 5V). In-rush current is around 1.5A.

  15. For use with the Pandaboard, the 33ohm resisters are required to be installed on the rear of the board.. correct?

  16. Hello Ward,

    You should remove 28 resistors on top side (marked as B and C sections), then install the same (or others, value from 0 to 33 Ohm) on bottom side R175-R203. Also, don't forget about J1 and J4 connectors.

  17. 1. May I know what is the interface to connect to Panda board ?

    2. Actually I am looking for a 15" display with integrated touch screen, do you have 15" panel ?

    ReplyDelete
  18. Hello Kushi,

    1. It is connected through J1 and J4 LCD connectors (see PandaBoard System Manual for details).
    2. We don't have 15" LCD and have no plans to sell it, sorry. You can use any of spare 15" LCD panels for notebooks - most of them have LVDS interface. But sourcing of 15" touchpanel could be a problem.

  20. Hello,

    Thanks.

  21. Hi,

    I have preordered one. Can you please confirm the same by emailing me back.

    Regards,
    Manu

  22. Hello vivek,

    1. Driver is not required for this LCD. If your system can work with usual LCD monitor, it will also work with our LCD panel. As to touchscreen driver - it is standard USB HID touchscreen, so I believe it should be supported by any recent Linux kernel.
    2. LCD bundle cost $134.99 + standard worldwide mail shipping $25.

  23. Hello Jerome,

    We ship worldwide. Yes, France in the list :)
