Sony SXRD 4K - Manual (Page 5)

TECHNOLOGY
Every data projector from Sony adopts a 3-panel projection system* that uses three display
panels. This system can project significantly bright and natural images. Yet to maximize the
performance of the 3-panel projection system, the display panel itself must provide
excellent resolution, contrast, and luminance characteristics.
To provide this, Sony developed the SXRD and BrightEra LCD panels using the most
advanced manufacturing technology available.
* The 3-panel projection system has different names depending on the display panel used. When the LCD panel is used, it is called the 3LCD projection
system. Whereas, when the SXRD panel is used, it is called the 3-SXRD projection system.
SXRD Technology
SXRD (Silicon X-tal* Reflective Display) is a ‘Liquid
Crystal on Silicon’-based display panel developed
by Sony using cutting-edge manufacturing
technology. The SXRD panel offers the following
advancements:
* “X-tal” is engineering shorthand for “crystal”.
‘Normally Black Mode’ System
In every type of projector system, displaying
absolute black is a major issue – as this helps to
achieve a high contrast ratio. In other words, the
contrast ratio of a projector depends on how
effectively the light from the source can be
blocked, so it does not leak through the display
panel. All Liquid Crystal Display (LCD) panels
control the amount of light to be projected by
applying an electric field to the liquid crystal gap.
In typical LCD panels, 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 panel, since the molecules near the
surface are less accurately controlled. This results
in a creamy black instead of a deep black. The
SXRD panel does not exhibit these characteristics.
This is because the ‘normally black mode’ system
displays black when the electric field is not
applied, and because all molecules are in the
correct alignment, the polarized light alignment is
also optimized. The direct result is a far deeper
black level, leading to a high contrast ratio. SRX-T110 SRX-T105
