DLP470TP: 4k display

Renan Santos Adriano

Part Number: DLP470TP

Hello Team,

My customer is developing an aerospace camera. The idea was to use the microdisplay as an object in the focal plane of a collimator, and use the collimated beam to illuminate the camera with images at "infinity" to test the camera in close to real conditions. They need a high resolution (4K) display, and they think DLP470TP can be used to it.

But some doubts on how it works, is the image obtained by the DLP microdisplay is already collimated? so in that case, could they directly project it into our camera without the need of using a collimator?

How are the images provided to the DLP? Is there any controller associated with it?
Can they provide the images using standard software or is it necessary for any additional software?

Regards,

Renan

    Hi Renan,

    Thank you for using the E2E forum!

    The DLP470TP is controlled by the DLPC6421 and is usually paired with a DLPA3005 as a power management integrated circuit.

    A member of our team will reach out by EOD Thursday (1/14) with information on the collimation.

    Regards,

    Austin

    Hello Renan,

    The typical illumination for DLP projection system is telecentric design.   The light beam into DMD is telecentric and I have a PDF file to explain the incoming light into DMD. The DLP470TP uses the TRP pixel architecture ( tilt angle 17 degree). The optics needs to F/1.7 or slower.

    The DMD is image plane and LED /illumination source is imaged on to the DMD. The light reflected from DMD is not collimated, you will need optic to relay it to your camera.

    Hope this answers your question.

    regards,
