The Wobulator

Images without Wobulation (top) are dramatically improved by two-position Wobulation, which doubles the resolution.

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 DLPtechnology 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.

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.
