Part Number: DLP3010EVM-LC
I have an application that requires displaying multiple static color images in sequence, each at 60hz. I'm hoping to get 6 images in the sequence, leading to a refresh rate of about 360Hz. The DLP3010-EVM (DLPC3478) claims a pattern rate of 360 Hz. Will this work?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

If you haven't seen it already this FAQ on the light control platform may be helpful. Internal patterns mode can only be used for 1D patterns (see FAQ definition for this). Are you looking to use 1D patterns? If not you will have to use external streaming.
Also, can you describe your desired images? Are they 1-bit depth or 8-bit depth? Could you give an example of the projection order and desireable characteristics? My understanding is you want the following:
Please let us know.

I'm still looking for a product recommendation. If anything you have will work with my application, please let me know.
I'm sorry for the delay. Unfortunately you will not be able to achieve an exposure period of 1/360 = 2,778us for an 8-bit image with RGB illuminators. I would also like to clarify that RGB means the entire image will be illuminated with a red LED, followed by green, then blue. In other words, your resulting image will be all white. Is this okay?
If so, the fastest exposure periods you will be able to obtain are as follows:
If you only need 1-bit images you will be able to achieve a much faster rate. Please let me know if any of those options work for you?
Now I'm more confused. I apologize. I think I misunderstood your nomenclature. Let's start over.
I want to display 2D color images in fast sequence. For example, image #1 might be a photo of an apple, image #2 might be a photo of a banana... I need each image to display 60 times per second. If there are only two images in the sequence, then each image would alternate on the screen. The total period would be 16,667us and in this period both images would need to be displayed. Each image would have a period of 8,333us. If we add more images, the total period of 16,667us stays the same but the individual period for each image would decrease because we're displaying more images during the same 16,667us.
I understand that each image would be made of 3 sub-images in sequence, each illuminated with the colors RGB. I assumed that 8-bit was how you achieved gray scale with these illuminators. Please correct me if I'm wrong. A totally white image is not useful. I thought I could achieve faster rates by loading the images into the controller rather than streaming them through the HDMI. Again, correct me if I'm wrong.
Based on your responses, it doesn't sound like this product can even display 2 images at that rate if 90Hz is the fastest it can go. When the datasheet claims that it can accept 120Hz framerates, what does that mean? Do you have any other products that you can recommend?
This is for a display application. I'm using it to test some downstream optics that will sync with the DMD and separate the images. Originally, I hoped to get 6 images in the sequence with 24-bit color. It sounds like this might be asking too much. So, now I want to know what the options are. If I keep the 24-bit color, how many images in the sequence can I get? If I reduce to one illuminator (e.g., white light?) at 8-bits, how many images can I get? (I assume the options are 1-bit or 8-bit for each illuminator? There isn't something in between?)
You mentioned 360Hz for the 6500 above. I assume this is for a single illuminator? If we go to RGB, then the effective frame rate would be 120Hz?
You can probably tell that I know very little about DMDs. Do you guys have a phone number? It would be way faster than communicating via the forums.
