DLP4501: 3d support clarification and EVM?

Thank you.

The link leads to an invalid page.

1) There's a reference design for a PCB utilizing the DLPC6501 and the corresponding LED controller here www.ti.com/.../toolssoftware ,
however I can't find info whether the design without modification supports 120Hz WXGA stereoscopic video input.

3) Also, info on how much current can be supplied to the LEDs with this reference design board would be nice, some optical engine manufacturers use LEDs with as much as 20W power.

4) Finally, can the reference design PCB accept 1080p @ 120 Hz input and downscale to 1280x800 @ 120 Hz?

Since the micromirror arrangment is trapezoidal and not orthogonal sending orthogonal pixels at native resolution and displaying on a trapezoidal DMD would cause loss of details/resolution. Sending higher res orthogonal signal and scaling that down to a lower resolution trapezoidal image would look much better.

Hello,

Sorry about the link here is the full url to our landing page for the third party evm: http://www.ti.com/tool/DLPC6401DISPLAYEVM

Based on what you are looking for I am not confident that the 6401 will suit your needs. Have you looked in our 4710EVM with 1080p solution: http://www.ti.com/tool/tida-01226 

Or the 3010EVM with 720p solution: http://www.ti.com/tool/DLPDLCR3010EVM

These platforms off DLP Controllers that have a bit more flexibility and have 3D video features built in.

Hello,

The DLP6401 has no features specifically for 3D. It does support 120Hz. I am not sure what other information you need to tell it to support your 3D application. 

The TI design you reference is not really an evaluation module. It is more like a design recommendation. does not specify a led driver set up or optics. Also there is not video processing front end so it would be required be done externally with video input be in 30-bit parallel. (See Below)

So if you were looking for an out the box evaluation module (something with a standard video input) I would recommend the third party EVMs that I mentioned before:

www.ti.com/tool/dlpc6401displayevm

Does that EVM look like it would suit your evaluation purposes?

Thank you.

No, that EVM only supports 2d 120Hz mode, and they don't provide reference design files.

I might as well just buy the optical engine (DMD, LEDs plus optics) from them and use the PCB design from the TI website, http://www.ti.com/product/DLP4501/toolssoftware (

By the way, is there a chance TI has some OEM PCBs manufactured and ready to sell to users? Or can help getting some manufactured?

I understand now. I will look into some of our design partners to see if any have a solution for your situation. I did find in the dlpc6401 programmer's guide a section pertaining to 3D. It looks like you design will require a special IC that will convert 3D video to something usable by the DLPC6401. It will also require some configuring some setting of the DLPC6401. See below.  

I will get back to you when I have more information.

Best,

Looking forward to it.

By the way, what is this .pcb format the reference designs come in and how can one export it to a more usable gerber format?

Hello Francis,

Our TI.com list many of our design partners along with the chipsets they specialize in. You should be able to find the who you will need to reach out to from the following link: www.ti.com/.../support-training.html

Hope that helps!

Either the info on the webpage needs updating or none of these companies support the DLP4501 DMD www.ti.com/.../optics-electronics.html

Whoops! You are correct, I linked you to our partners for our industrial chipsets. Here is the proper link:  

We have some out of the box optical modules as well as design houses that can further support you.

Best,

~Danny W

The companies in the above link provide only optical modules, no PCBs to drive them. Some make drivers but only for bulk 1000+ order. Not suitable for prototyping phase.
