The industry’s highest* native contrast ratio of 50,000:1!
Native Contrast ratio is the intrinsic ability of the projector to
show the complete range of image contrast simultaneously.
In the DLA-RS20, JVC changed the structural design of the
optical section from a conventional L-shape to a straight
configuration which helps to reduce light leakage. The
enhanced wire grid optical engine dramatically improves the
precision of light polarization, helping to prevent light spilling
onto the projection lens. Combined with a highly efficient
lamp, a brightness of 900 lumens has been achieved.
Realizing that increased brightness may not be desired for
all viewing environments and screen sizes, JVC has added
a 16-step Aperture Brightness Control that allows users to
achieve perfect screen brightness and adjust for ambient
lighting conditions. The Aperture Brightness Control also
serves to further enhance native contrast ratio, up to 50,000:1.

Conventional projector with dynamic iris
DLA-RS20
The dynamic iris is opened
for bright scenes to make
peak values brighter while at
the same time, making
black level lighter than it
should be.
The dynamic iris is closed
for dark scenes to make
black level appear darker
while at the same time,
making peak values darker.

How the wire-grid polarizer works
The 0.7-inch full HD D-ILA device
can display peak whites and deep
blacks on the same field of a
picture. This provides extremely
sharp contrast for more vivid and
natural color reproduction.
High-performance 2x motorized zoom lens
The DLA-RS20 is equipped with a new 17 element lens that
uses ED (extra low dispersion) glass, producing very minimal
chromatic aberration. The lens has a motorized focus and
2x zoom that can be controlled from the wireless remote.
And to display the deepest black possible, this new high-
precision lens is also equipped with a 16-step lens aperture
that allows adjustment of brightness according to user
preferences and usage
environment. What's more,
the high-precision lens also
reduces chromatic
aberration and color
bleeding significantly.
Excellent color rendition
Color Management interpolates
colors individually by R, G, B, C, Y,
or M, in three separate axes of
color phase, chroma saturation,
and brightness. Up to three
customized color settings can be
stored for future use.
