Selecting the right DLP product for HUD

Other Parts Discussed in Thread: DLP4500, DLPC350

Hi,

I am working on a research project and looking for the right DLP projector for an Automotive HUD solution. There was a white paper https://www.ti.com/seclit/wp/dlpa057/dlpa057.pdf published sometime back by TI regarding it's DLP 3000-Q1 Automotive Qualified Chipset http://www.ti.com/lit/ml/dlpt024b/dlpt024b.pdf . I cannot find this product line anymore. 

What would be a replacement product if I want to achieve the same functionality ?

Additionally, i have been reading more about the 2 different product lines from DLP : Advanced Light Control & Video and Data Display. Based on the product line, can someone help me with the questions below :

1) What is the difference between eval module and dev kit ? Which one would be the right fit for my application ?

2) Where can I buy the DLP-3000-Q1 chipset ? Is it still in production ? If not what are my options for a multicolor HUD DLP projector

3) I believe and quote me if I am wrong. The DLP can be connected to a CMOS or CCD camera. However, I am having trouble searching for info, if the DLP can take the input source directly from a camera as a live video and project the output after processing the video and with help of some GUI overlay graphics. 

4) Can the process workflow be designed/mapped to additionally add Arduino to provide the GUI/graphics(Augmented Reality) with Source (camera), processor(Arduino), and output (DLP Projector)

Would appreciate any help in this regards as I am looking to buy the module and start the project ASAP.

Regards,

Vijyat

    Vijyat,

    TI does not offer a catalog DMD chip that is automotive certified at this point in time.

    1. Can you clarify which products you're looking at?

    2. At this point, you can't purchase a DLP3000 Q1. For HUD, I might take a look at the DLP3000, DLP4500 or DLP6500. What you need will depend on your project's specifications.

    3. This is possible. Our Lightcrafter EVM allows something like this, I recommend you take a look at the user's guide for more info: www.ti.com/.../dlpu006e.pdf, sections 1.5 and 2.12. This works due to a hefty processor on the EVM - the DLP components do not provide this functionality by themselves.

    4. I'm not aware of any limitations here. I will mention that the source code for the Lightcrafter EVM is available, which is a great starting point. Further, the DLP ALC SDK is also available which could provide further insight into the software side of things. 


    Hope this helps,
    Paul

    Hi Paul,

    Thank You. You managed to answer most of my questions. Since my project is specifically related to Augmented Reality using HUD.

    So now I would like to narrow down my options regarding the DLPLightCrafter 4500 EVM module. is there a reason why this particular EVM listed under the Advanced Light Control Product Tree and not the Video and Data Display. ? Correct me if I am wrong, the DLP4500 does not have any I/O triggers available, which I believe I would need in order to add additional embedded systems like Arduino ? So, in answering my own question you feel the DLP Lightcrafter 6500 would be the right choice ?

    Thanks again Paul. much appreciated

    The Lightcrafter 4500 is an Advanced Light Control device. The DLPC350, which is the controller for the DLP4500, does have both input and output triggers. It is used in many applications including machine vision and 3D scanning where triggers are a must.

    I can't say which EVM is the right choice for you because I don't know your product requirements. If you want a device that has I/O triggers and has optics on the EVM, then the Lightcrafter and Lightcrafter 4500 are your only options. If you want to use your own optics, the 6500 is probably a better choice.

    I don't have any product requirements or specifications at this point. This is a Proof of Concept project, we just have the end goal in mind, to make an augmented reality HUD. So i guess i will start with DLP lightcraft4500 for now.

    Thank You
