High 1800:1 contrast ratio
The SRX-Series projectors offer a high contrast ratio of more
than 1800:1* through the use of Sony’s unique SXRD device.
The SXRD imaging device itself achieves a contrast ratio of over
4000:1. This stunning picture quality makes the projectors ideal for
applications in which dynamic range is essential.
The high contrast ratio has been achieved through two key technolo-
gies – the exclusive ‘Vertically Aligned Liquid Crystal’ system and an
extremely thin liquid crystal cell gap.
*The contrast ratio is measured from a screen offering a gain of 1.0.
Vertically Aligned Liquid Crystal system
In every type of projector system, displaying absolute black is a major
issue in order to achieve a high contrast ratio. In other words, the con-
trast ratio of a projector depends on how effectively the light from the
source can be blocked so it does not leak through the imager.
All Liquid Crystal Display (LCD) devices control the amount of light to
be projected by applying an electric field to the liquid crystal gap. In
typical LCD devices, black is produced when an electric field is
applied across the liquid crystal cell gap. However molecules near the
surface of the glass substrate may not be accurately controlled due to
the influence of the alignment film. This is not an issue for bright
images. However, when displaying dark images, light may tend to leak
from the LCD device, since the molecules near the surface are less
accurately controlled. This results in a creamy black instead of a deep
black.
The SXRD device does not exhibit these characteristics. This is
because the Vertically Aligned Liquid Crystal system displays black
when the electric field is not applied. And because all molecules are
in the correct alignment, the polarised light alignment is also
optimised. The direct result is a far deeper black level, leading to a high
contrast ratio.

4K resolution
Sony SXRD display devices deliver the exceptionally high resolution
of 4K (4096 H x 2160 V pixels at 1.896:1 aspect ratio), more than four
times as many pixels as full HDTV (1920 x 1080, 16:9 wide screen
format).
The SXRD device helps to achieve this resolution by incorporating
nearly 8.85 million pixels per imager at a narrow pitch of 8.5 micro-
metres. These high-density pixels, which are one quarter the size
of pixels projected using typical 2K resolution projection systems (2.2
million pixels), provide an amazing picture. Even in multi-screen mode,
full HD and 2K resolution per quadrant is possible. The resolution
available from the Sony SRX-Series projectors enables a new level of
visual projection.
