Specific Eval Target board for 3D NED design?

Hello Liyen,

We have two EVMs which can fit your application. It is highly depending on your application meaning what resolution, current and lumens you need to implement.

I would suggest that you take a look at our two EVMs and let me know which one would meet your requirements and we will go from there.

• DLPDLCR2010EVM DLP® LightCrafter Display 2010 EVM:  0.2 inch diagonal, resolution 854 x 480

• DLPDLCR3010EVM DLP® LightCrafter Display 3010 EVM:  0.3 inch diagonal, resolution 1280 x 720

Both EVMs contain a DLP Display Controller Chip and the DLPA2005 PMIC/LED Driver on-board.

Thank you,

Nadine

Hello Nadine,

    Thank you so much for the pointer, as matter of fact, I've seen both eval targets on TI DLP websites,

but I wonder what are the reasons that you specifically think these two could be good candidates for

3D NED projection design? I'd said that I prefer 3010 at this moment because the supported resolution

matches our goal, but depends on main app media processor's cap to crunch A/V data, I may have to

downgrade to lower resolution later.  BTW, since our app is A/V media oriented, I wonder if the main

DLP processor can handle certain level of computation tasks like real time ANC? and please correct

me if this is wrong, the target is powered thru USB connection?  Much appreciated again...

Hello Liyen,

I would like to refer you to one of our white papers "DLP Technology for Near Eye Display (NED)" which gives a full description of why our chipsets are a good match for NED. Both EVMs are powered with a 5V power supply. The USB port is for the GUI communication.

Our DLP controller processes in real time with 60 frames per second for the DLP3010EVM and the DLP2010EVM but the controller is capable of handling frame rates in a range of 10 to 123 Hz.

Please let me know if you have any further questions.

Best regards,

Nadine

Hello Nadine,

   Much appreciated for quick reply, it is our first project effort to address wearable type of 3D gadget so I quite

serious stressed on 3D feature, indeed the white paper you referred was the very first doc I went thru to gain

knowledge about DLP tech, however, it doesn't emphasis on 3D but various types of DLP applications on NED,

since I presume there to be two set of DMD/LED sources to cope with the stereo views of an image frame, I

wonder if there such specific DLP controller which can handle two sets simultaneously, that shall be very

cost effective for our goal, could you pleae point me  somewhere that I can find more specfic info of 3D DLP

design? On the other hand, I wonder if such DLP controller having extra processing power to address some

generic tasks, such like noise reduction as I saw there're audio links on both 3010 and 2010 EVM, what kind

of audio interface are there and do I have flexibility upon sampling rate? I merely need very low, such like 2 kHz

sampled stereo audio,  finally, what kind of development platform is for these DLP target? more or less linux

flavor or simply TI specific?  thanks again

Hello Nadine,

   Thank you so much for reply, it will be good to chat a little bit more on details, however,

we started this effort just a few month ago, which came my crazy idea to try something

new, I don't have clear view of how to port DLP design onto a smart glass and 3D view

is one most crucial feature that we want to create, so if possible could you please share

any pointers that can help on this matter?  after all, I still would like to know if I can use

DLP controller to do certain level of audio signal process?  I'll contact you again asap

once I am ready to talk more over the phone, thanks a lot again

Hello Nadine,

   One more very specific question, we are very critical on target dimension, may you provide 

us the exact dimension of each board, lightcraft display, light engine and main ctrl board

for each, 3010 and 2010? please, thanks
