DLP3010EVM-LC: Is this the right EVM for fast projection?

Part Number: DLP3010EVM-LC

Hello,

We're looking for a high frame rate projector for visible light (for studying human vision). We need at least 1000 Hz, with the highest resolution and bit depth possible. We'll be using extrernal data over the HDMI input. I'm looking mainly at the 3010 and 4500 evaluation modules. I have a preference for the 3010 because of its more standard resolution and square rather than diamond pixels, and lower price. The 4500 seems to have a slightly higher frame rate at 1-bit depth (2880 vs. 2488 Hz) and to be slightly more luminous. However, the 4500 is significantly more expensive. Are there some advantages of 4500 that I've missed?

Thank you very much,

Mark

    Hi Mark,
    Welcome to DLP Forum and thank you for your interest in DLP technology.

    I assume you need an evm with optical engine. Have you also considered DLP4710EVM-LC Lightcrafter EVM? The DLP4710 DMD has 1920x1080 resolution and the brightness is 600 lumens. The DLPC3479 controller used in this EVM can support 1 bit pattern upto 1440 Hz frame rate.

    www.ti.com/.../dlp4710evm-lc

    This EVM offers highest resolution and brightness along three EVMs namely DLP2010EVM-LC, DLP4500 and DLP4710EVM-LC.

    The DLP4500 has diamond pixel and if you are detecting single pixel line then your application has to adapt for diamond grid. Please see the example in the DLP4500 Lightcrafter EVM user guide (page 11, Figure 1.5)

    www.ti.com/.../dlpu011f.pdf

    The DLP4500 (912x1140 ) has ~13% more pixel than DLP3010 (1280x720).

    Thank you, Vivek, for your reply. I'll definitely take a look at the 4710.

    In the meantime, I have another question. Say I have the 3010 and want to operate it in the 1-bit 2488 Hz mode with external video data through the HDMI input. How does that work, exactly? I understand that I'll be compressing frames in the different bit planes of my image, right? But if my video card outputs at 120 Hz, and I have 24 bit planes, that works out to 2880 Hz. But if I'm only at 2488 Hz, what happens? Do I not use all of the bit planes? Or do I need to lower the output frequency of my video card from 120 to roughly 103 Hz?

    Thank you,

    Mark
