DLP4710EVM-LC: high brightness short throw 4710-LC

Vadim Gorev

Part Number: DLP4710EVM-LC
Other Parts Discussed in Thread: DLP4710

Hello, we are looking for HD platform for structured light
We noticed that TI offers the 4710EVM-LC, however based on
previous test we ran on conventional video projection variants
that deliver HD resolution, we learned that we need at least
1000 ANSI LM to match our testing environment. We also
require working at close distance to the target at a throw ratio smaller
than 1 preferably 0.6 to 0.8, does TI offer any short throw version to 4710EVM-LC?

Vadim,

The stock design of the DLP4710-LC only features the one configuration. However, there are optical engines with the specs that you are looking for available for this chipset.

I recommend you start off by browsing the Optical Module Search Tool (https://www.ti.com/tool/DLP-OMM-SEARCH), which has a directory of optical modules for many of our chipsets.

You should go to the "Light Control" tab and search for DLP4710 optical modules. I see a couple options in there which have the throw ratio and brightness requirements you are seeking. You will likely need to adapt the DLP4710-LC EVM reference design (https://www.ti.com/tool/TIDA-080005) if the flex cable connection is different on whatever optical module you use.

I hope this helps. Let me know if you have further questions.

Regards,

Philippe Dollo
