DLP3010EVM-LC: Displaying 2D pattern at high refresh rates

kanish Srivastav

Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLPC3470, DLPC3478

Hi,

I want to project 2D monochrome patterns at a high refresh rate. I want to be sure that the projector is capable of projecting 2D patterns at high refresh rates (around 1440HZ or higher). Please help me out.

Hi Kanish,

Welcome to TI E2E forums and thanks for showing interest in the DLP technology.

You can display high speed 2D patterns using the external pattern mode of DLPC3470/8/9 chipset. Please refer to the following FAQ for more information -

Hi,

What refresh rate can I go up to when using 2D images.

Kanishk,

The DLPC3470 (supports 0.2" WVGA DMD) and DLPC3478 (supports 0.3" 720p DMD) controllers both support high-speed pattern rates up to 2500Hz (1-bit patterns). This is documented in the DLP Controller datasheets:

https://www.ti.com/lit/ds/symlink/dlpc3470.pdf

https://www.ti.com/lit/ds/symlink/dlpc3478.pdf

For easy prototyping, there is a Display and Light Control GUI (https://www.ti.com/tool/DLPDLC-GUI) which can be used with the EVMs for these chipsets (https://www.ti.com/tool/DLP2010EVM-LC and https://www.ti.com/tool/DLP3010EVM-LC) to program custom patterns for streaming.

I hope this helps.

Best Regards,
Philippe

Hi,

From my understanding, after seeing the software the projector is only capable of projecting horizontal or vertical patterns in the internal mode. We want to know the maximum rate at which it can project monochrome 2D external patterns (1 Bit).

Hi,

Also let me know how can I do so. My refresh rate in the GUI is locked at 60Hz for external patterns. I don't have the evm yet.

The maximum rate at which 2d external patterns can be displayed is 2500Hz. Kindly refer to the following thread for more info - https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/778576/faq-sequence-timings-for-dlpc347x-light-control-platform
