The most amazing picture imaginable is what you will see with JVC’s HD-ILA
rear projection TVs. Built on JVC’s 3-chip D-ILA technology, a revolutionary
Micro-display technology that will give you the most incredible picture
imaginable, D-ILA takes every factor from resolution, brightness, color
reproduction, cabinet styling and even device longevity one step further
than all the others.
Microdisplays like LCDs and DLP offer all the advantages of CRT
based rear projection TVs, plus add a whole lot more. Advantages
include significantly higher resolution capabilities and much brighter
images; no periodic re-convergence requirements—making them
low-maintenance; and they offer increased viewing angles and
much slimmer and light weight cabinet designs. Now HD-ILA resets
the bar, redefining microdisplay with new standards for quality,
product longevity and brightness and resolution capabilities.
What makes microdisplay devices unique from
other forms of rear projection TVs (RPTVs) is
that they are driven by digital microchips and
light projection technology and CRT technolo-
gy. The most common forms of microdisplay
devices are Liquid Crystal Display devices
(LCDs), Digital Micro-mirror devices (DLP), and
Liquid Crystal on Silicon devices (LCOS).
D-ILA (Direct-drive Image Light Amplifier)
devices are a highly sophisticated form of
LCOS that offer distinct advantages over the
other types. D-ILA combines the use of a single
high power user-replaceable lamp, three verti-
cally oriented LCOS microchips (1280 x 720),
one for each RGB color, a precision focus lens,
and a truly unique polarized beam splitter to
combine all the colors of the images.
D-ILA is resistant to screen burn-in issues that
can occur from video game play and other
static images. Other panel display types, CRT
TVs and RPTVs are all prone to screen burn-in
damage which is permanent and can ruin your
TV viewing experience.
D-ILA microchips add an inorganic alignment
layer that maximizes chip production and sta-
bilizes device performance. This unique struc-
ture insures a longer life device and maximum
performance every step of the way. The result
is television images consistently superior in
resolution, grayscaling, brightness, and color
reproduction that doesn’t diminish over time.
There are three primary technologies that lead the microdisplay revolution —LCD devices, DMD
devices, and LCOS devices. But D-ILA has two distinct advantages over the other microdisplay
technologies, both stemming from its superior device design. D-ILA is the only device type that
can boast maximum mega pixel placement capacity and no loss of light during the image
production process. LCD and DMD, and even other forms of LCOS, invariably lose some space on
which mega pixels can be placed and some of the original light source will be blocked—both of
these limitations are a consequence of their design.
LCD — fair brightness capability
LCD is a transmissive technology that allows light to pass through liquid crystal microchips to
provide image data to the display screen. The main drawback of LCD is that transistors are
required on each pixel, and wires must run between each pixel to transmit the image data.
Combined, these wires and transistors limit both the total area through which light can pass
(limiting brightness)as well as the total area on which pixels can be placed (limiting the
megapixel ratio).
DLP — reduced brightness capability
Digital Micro-mirror Devices known as DLP employ a reflective technology that uses micro-mir-
rors on hinges to reflect image data to the display screen. The main drawback of DMD is that a
hinge is required on, and a space is required between each pixel to allow the mirrors to move.
This space between the pixels and the space occupied by the hinges both limit the total
reflective space available per pixel (limiting brightness)as well as the total area on which pixels
can be placed (limiting the megapixel ratio).
D-ILA — best available brightness capability
HD-ILA employs D-ILA, also a reflective technology, but it utilizes a special form of LCOS pixels
which require virtually no space between them. No space between pixels allows D-ILA to yield
the highest aperture ratio (reflective area) and therefore the greatest total area for placing
mega pixels is maximized. D-ILA further improves upon LCOS by using vertically oriented
pixels and by adding an inorganic alignment layer that both stabilizes device performance and
maximizes chip production.
