The Wobulator
The technology story:
HP Visual Fidelity and

Wobulation

HDTV and HP Visual Fidelity
Thanks to HP's Visual Fidelity technologies—the
power behind the picture—our HDTVs deliver
unrivaled image quality and color brilliance.
In LCD and plasma models, HP Visual Fidelity
technologies provide an advanced video pipeline
that combines photorealistic sharpness enhance-
ment, scene-by-scene contrast adaptation keyed
to the room's ambient lighting, and a 3D color-
enrichment system.
HP Visual Fidelity includes technologies such as
Wobulation, which doubles the pixel resolution to
provide brilliant, crisp, true-to-life images. (See
illustration, above.) The lamp is brighter, offering
more accurate, vivid colors and an ultra-wide
viewing angle. And DLP ™ technology fine-tunes
each individual pixel for a cleaner, sharper image.
All HP HDTV models feature high contrast ratios for
brighter lights and deeper darks. That means truer
blacks—enhancing image sharpness and power,
whether the scene is action-packed or brightly lit
or darkly shadowed. It means subtler color detail.
And it means increased tolerance of ambient light.
The bottom line? A viewing experience like no
other, rich with stunning detail and true-to-life colors.
Images without Wobulation (top) are dramatically improved by
two-position Wobulation, which doubles the resolution.
Microdisplay TV and Wobulation
Wobulation is a funny name for a great technology.
And it's another great example of HP ingenuity at
work—leveraging our industry-leading inkjet tech-
nology into new and dazzling consumer products.
Here's how: both printers and digital projectors
create a color picture from a matrix of primary
color points. Historically, print resolution was
increased by placing more and overlapping ink
droplets within the same size grid; initially,
300 x 300 dot-per-inch (dpi) resolution became
600 x 300 dpi. That yielded significantly better
image quality from the same size dots of ink.
HP engineers simulated applying the same principle
to "droplets" of light, with exciting results. Same
size spots, yet dramatically improved image quality.
In fact, the resulting light-imaging technology—
Wobulation—doubles the addressed resolution of
non-Wobulated, digitally projected images, without
diminishing their renowned crispness. This technology
virtually eliminates the screen-door effect commonly
seen in other displays. And it's accomplished with-
out expensive modifications, like changing the light
modulator or increasing pixels.
Better resolution, eye-popping picture quality,
virtually no increase in cost. So, HP customers who
choose our MDTVs get the best possible HDTV
viewing experience at a price they can afford.
