I am thinking of buying a new DLP lightcrafter

So I broke one DLP Lightcrafter 3000 EVM  and my ex-colleague broke another one. I think that is really a lot for an EVM. Anyway, I need it so I will buy another one.

Now I have some questions about which one to buy if I want to change:

* Which one has a wider Field of view amongst  the DLP Lightcrafter 3000, DLP Lightcrafter 4500, DLP lightcrafter Display 2010 or DLP lighcrafter Display 3010?

* Can I also remove the LEDs from  DLP lightcrafter Display 2010 or DLP lighcrafter Display 3010?

* Can I project patterns (as I could do on my DLP Lightcrafter 3000 EVM) using  DLP lightcrafter Display 2010 or DLP lighcrafter Display 3010?

Thanks, Pepe

    Hi Pepe,

    The Display Lightcrafters will not allow you to project patterns in pattern mode as you were able to do with your Lightcrafter. This pixel accurate mode is a feature to the Advanced Light Control group of products in DLP.

    I would recommend posting your question about removing the LEDs from the Display Lightcrafters in their forums - you'll be able to get a better answer there: e2e.ti.com/.../984

    For your question about FOV, that depends on your projection distance and is calculated using a little bit of trigonometry. Most projectors don't specify this because you're not recording, you're displaying (it is a commonly found spec for camera lenses though!). That being said, a good parameter to look at is the throw ratio. This will tell you the ratio of image width to projection distance. The ratios are as follows:

    LCr3000 = 1.66, 16:10 aspect
    LCr4500 = 1.20, 16:10 aspect
    LCrD2010 = 1.65, 16:9 aspect
    LCrD3010 = 1.65, 16:9 aspect

    Using these throw ratios and the aspect ratios of each device, you can calculate FOV and choose whichever device is appropriate for your application.

    Hope this helps,
    Paul

    Hi Paul,

    Thanks a lot for your clear explanation. You are always very helpful. I think the LCr 3000 is still the best option for me.
