DLP2010: Is modulating the LEDs in theory relevant if a monochrome whitelight projection is needed?

Hello, thank you very much for the info.

First, can you please tell me, besides the issues you mentioned, if what I described will work, visually? In other words, do I understand the purpose of the modulation of the LEDs?

Now, my intended usage is light field display. The specific design I am working on requires very fast refresh rates (>1000 Hz), this can be achieved by using monochrome frame and Floyd-Steinberg dithering in software.
So I need very fast refresh rates in monochrome, but still send the frames via HDMI.

The reason I want to use the DLP2010 DMD is the cost, using other chipsets will be too expensive to make this an affordable consumer product.

Few weeks ago I had a private message exchange with another employee and he gave me the impression that high (>= 960Hz) refresh rates with HDMI input were not possible with the DLP2010 DMD if in monochrome mode more than one LED is needed to be turned on. And he offered me to use other bigger chipsets such as 4500 which I explained will make the product not affordable to consumers.

But it may have been a miscommunication and he may have been saying what I want is not possible with the DLP2010 Evaluation module rather than the DMD.

Are you saying with that other DLPController chip you linked to the DLP2010 DMD can be ran via HDMI input at 24x120= 2880 Hz and the DLPC3470 can be set to use all 3 LEDs for each monochrome frame rather than one of the LEDs as is the limitation with the LIghtCrafter2010/DLPC3435?

If so, even better.

Then I will ask, is Texas Instruments or one of its partners selling an evaluation module which use this DLP2010 DMD/DLPC3470 controller combo, with a 120Hz HDMI input support?

Thank you for clarifying what the upcoming chipset will be capable of. However, I am confused. Do the optical engine providers/ design service providers have some DLPC3470 chips now, and able to write firmware for it? Because if not then how can they create a board around it?
Earlier you said the samples for it are available but I am not sure what that means when it comes to me and the above partners being able to get them today.
And is there any estimated date for mass production? It may be few months or a whole year, I would like to know when to plan my product for consumers.



And you explained that the The Power Management IC and DLPC3470 still cannot have all LEDs on at the same time in monochrome external pattern streaming mode. Well then, I will get back to my original question. "Is modulating the LEDs in theory relevant if a monochrome whitelight projection is needed?"
Because, again, if I understand how DMDs work, it shouldn't matter whether they all modulate or don't modulate, for monochrome frames.
Besides color shifting due to bad thermal management and more power consumption/heat which you mentioned, is there any reason my proposed method may not work?

Thank you.

I checked the datasheet and the info is confusing and maybe contradictory to what another employee from TI told me before.

I expected to be able to have 2880Hz monochrome framerate by streaming and splitting 24 bit HDMI frames at 120Hz into individual 1 bit frames (24x120 = 2880) which one of your employee said will work with this IC however the datasheet only mentions "8-bit Monochrome". Monochrome is monochrome (1 bit), what on earth is this new term "8-bit Monochrome" term?

I think the term "8 bit monochrome" is misleading, if it's more than 1 bit its grayscale and should be labelled as such, not "monochrome". I understand the reasoning in that "grayscale" is understood as a shade between black and white and "monochrome" is used to refer to single color but that may just cause confusion.

"This device does support up to 2880 Hz 1-bit pattern."

In HDMI streaming mode?
