DLPDLCR3310EVM: DLPDLCR3310EVM Contrast ratio (full on, full off) and Contrast ratio for checkerboard pattern

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
