Part Number: DLPDLCR3310EVM
Hi,
Can someone tell me the following;
a) I want to know the contrast ratio of DLPDLCR3310EVM for full on, full off and checkerboard pattern.
b) Also where can I find the contrast ratio of all the DLP series EVM having optical module, controller and power section integrated in them.
Thank you,
Vedashree.
Hello Vedashree,
I am checking about this with my team. Will get back to you by early next week.

Hello Vedashree,
Thank you for your patience on this response.
We expect the Full on/off contrast to be in the range of 400:1, although we cannot specify the contrast value. With a custom built engine, much higher contrast can be achieved by designing the optics to a slower F#. This typically will have an inverse relationship to the brightness. Higher brightness with a laser based optical design typically will achieve 2500:1 by using slower F#s, such as f#3.
We typically do not measure ANSI Checkerboard contrast on our Pico projectors as the size and cost of the projection lens impacts the results. Values will vary significantly.
Kind regards,
Austin
