Dynamic Iris: Deeper Blacks, Brighter Whites, and Vivid, True-to-Life Colour

Incorporating Panasonic exclusive technology, the Dynamic Iris opens and closes with exceptional speed and precision as the input signal changes, resulting in accurate, real-time control of the light striking the DMD chips. The Dynamic Iris is posi-

tioned immediately after the light synthesiser and before the integrator, so it has minimal adverse effect on the overall light uniformity across the screen.

Blacks and other dark portions are washed out.

Competitor B

Thanks to functions such as lamp power switching, the blacks are not washed out. The white portions, how- ever, become dim and dull.

Dynamic Iris and Dynamic Gamma Dynamic Iris quickly fine-tunes the lamp output with 256-step precision. Dynamic Gamma preserves the bright- ness in bright portions, helping main- tain a wide dynamic range.
