Page 2: Introduction
Since that time, Sony 4K projection has become a fixture in auditoriums, research universities, flight simulators, control rooms and trade shows as well as movie theaters. In short, Sony 4K is called on for any application that demands ultimate size, resolution and picture quality. And Sony has extended the product line, adding two models with a pre-installed DVI input (SRX-S110 and SRX- S105) and two dedicated Digital Cinema models (SRX-R220 and SRX-R210). -

Page 4: Sony And Digital Projection
To casual observers, Sony's involvement in Large Venue and Digital Cinema projection may come as a surprise. But industry insiders understand Sony's deep involvement in the technology of digital entertainment almost every step of the way, from acquisition and production to postproduction and projection. - Page 5 Sony Pictures Entertainment. Not only is Sony actively involved in digital production of movies and television shows, but Sony Pictures Imageworks is also an innovator in photorealistic digital effects. And Sony Pictures Studios offer world renowned production and postproduction facilities.

Page 6: 4K Resolution
"4K" refers to an image that's 4 x 1024, or 4096 pixels wide. Sony 4K projectors achieve a resolution of 4096 pixels horizontal x 2160 pixels vertical. This is slightly more than four times the pixels of the highest high definition TV specification (1920 x 1080). - Page 7 This unwanted artifact is often called "screen door effect," because the picture appears to be viewed through a screen door. Sony SXRD 4K projectors minimize both artifacts. First, with SXRD the gaps between the pixels are unusually narrow in proportion to the live image area.
- Page 8 1/4 the area of HD pixels at a given screen size. In this way, the gaps are rendered all but invisible with SXRD 4K projection. Here's an enlargement of a section of the screen where an HD projector shows four pixels (left).
- Page 9 But you do get a noticeably smoother picture. Thanks to the four input slots, Sony 4K SXRD projectors can also accept four HD inputs to display four simultaneous high definition images. Each image appears complete in its own quadrant of the common screen. And each retains full 1920 x 1080 resolution.
- Page 10 These so-called "1080p" home televisions include LCD flat panels, microdisplay rear projection televisions and even a few plasma panels. These TVs are offered not only by Sony, but also by Hitachi, JVC, LG, Mitsubishi, Panasonic, Samsung, Sharp and Toshiba. Computer displays are also migrating to ever higher resolutions.
- Page 11 • Casino Sports Book. With ever larger slices of the sports calendar going high definition, SD projection will soon look boring and dated. Sony 4K SXRD projection supports up to four simultaneous high definition feeds on a single screen. External processing can display even more windows of standard definition, high definition or computer-based content at full or scaled resolution on the 4K screen.

Accurate Motion Rendering. Some displays can render still pictures beautifully, yet introduce unwanted blur during fast motion sequences. Slow panel switching is the culprit. Sony aimed for high switching speed. • High Contrast Ratio. Resolution by itself does not guarantee picture quality. - Page 13 SXRD panel. The acronym is short for Silicon X-tal Reflective Display, where "x-tal" is engineering shorthand for "crystal." More than 8 megapixels on an inch and a half of silicon, this is Sony's 4K SXRD panel. The four input ribbons correspond to the projector's four input slots and the four 2K quadrants of the panel.
- Page 14 Liquid Crystal, toward the screen. Polarized Light Filtered Light Simplified view of Sony's optical engine. It performs polarization with a series of Polarized Beam Splitters external to the SXRD panels themselves. Where H-LCD panels include all three of these elements, SXRD panels include only one: the liquid crystal.
- Page 15 Photomicrograph of the SXRD panel silicon backplane in cross section. Unlike conventional LCoS panels, which are notoriously difficult to manufacture, the SXRD panel uses a production process that Sony has perfected in the company’s own, dedicated manufacturing facilities. This has enabled Sony to bring SXRD technology smoothly into production, while taking advantage of its many benefits.
- Page 16 1920 x 1080 HD resolution. Critics were dazzled not only by the resolution but also the stable color and vivid contrast. Sony soon incorporated the same 0.78-inch diagonal SXRD panel into the Qualia 006 home theater rear projection television.
- Page 17 At the time of its launch, the 0.61-inches diagonal third-generation SXRD panel was the world's smallest microdisplay to achieve full 1920 x 1080 resolution. This device is featured in Sony's BRAVIA® VPL-VW100 and VPL- VW50 home theater projectors. With panel sizes from 0.61 to 1.55 inches and pixel counts from 2.0 to 8.8 megapixels, SXRD technology is also highly scalable.
- Page 18 Sony's 4K SXRD panel has a pixel pitch of just 8.5 micrometers. In comparison, a human hair is roughly 70 micrometers thick. It is this 8.5-micrometer pitch that enables Sony to deliver 8.8 Megapixels on a device not much bigger than a...
- Page 19 H-LCD panels. In the case of the 4K panel, the distance from the center of one SXRD pixel to the center of the next is 8.5 micrometers, while the inter-pixel gap is just 0.35 micrometers! According to Sony's review of currently available technology, this is the world's smallest inter-pixel spacing.
- Page 20 4.0 μm A thinner Liquid Crystal layer (right) means fewer LC molecules to twist and more available power to twist each molecule. The result? Faster response. In practice, response time decreases dramatically as you reduce the LC layer thickness. So reducing the panel thickness by 50% means cutting the response time by more than 75%.
- Page 21 Contrast, an essential requirement of any display system, is measured as the ratio between the brightest possible bright and the blackest possible black. Sony's SXRD panels achieve superb contrast ratio, thanks to three distinct innovations. • Sony-designed Vertically Aligned Nematic (VAN) liquid crystal. Most H- LCD projectors use Twisted Nematic (TN) liquid crystal, which normally displays white.
- Page 22 Together with Sony's spacer/sealer, this maintains cell gap uniformity to a highly precise ±3%. Sealing/Spacer Area Plan view, not to scale, of Sony's 4K SXRD microdisplay panel. By locating the Sealing/Spacer outside the active picture area, the SXRD design maintains maximum contrast.
- Page 23 Thanks to these features and additional refinements to the SXRD panel structure, contrast is substantially improved over H-LCD designs. The contrast ratio of Sony's 4K SXRD panel alone is better than 4000:1, when measured with a conoscope, a tool for analyzing the optical properties of bifringent materials.
- Page 24 Sony's design program for SXRD projection called for the closest possible fidelity to the original picture. For this reason, SXRD projection does not resort to color wheels, optical actuators, special dithering or sub-pixel processing. Color Wheels. These are a throwback to the mechanical color television proposals of the 1950s.
- Page 25 Fly Eye 2 Mirror C This schematic view of the Sony 4K light engine shows the three SXRD panels and the nearly equal-length optical paths for Red, Green and Blue. This simplified rendering shows the SXRD panels, Main PBS blocks and the final Cross Dichroic Prism, where the three colors combine.
- Page 26 Optical Actuators. Most microdisplay projectors offer a one-to-one relationship between the pixels on the microdisplay and the pixels on the screen. But in a move oddly reminiscent of interlace scanning, recent projection systems divide each display frame into two "subframes." A pivoting mirror outside the display panel called an optical actuator toggles the screen image back and forth.
- Page 27 Thanks in part to the pitch of the SXRD pixels, Sony projectors do not use an optical actuator. Each pixel has its own, unique space on the screen, not shared with any other pixel. And the SXRD system displays all the pixels, all the time.

Page 28: The Projectors
Sony now offers four SXRD 4K projectors designed for Visualization, Simulation, Auditoriums and Postproduction, the 100 Series. The four projectors are differentiated by light output, input configuration, how they accept 4K signals and maximum refresh rate. Projector Model Brightness, Lumens... - Page 29 Microdisplay projection lamps are not simply responsible for screen brightness, but also for color gamut. Sony chose a Xenon lamp both because Xenon is recommended in the Digital Cinema Initiatives (DCI) specification and because it delivers a flat and wide spectral response. Xenon is capable of an extended range of colors far beyond that used in television.

Page 30: Optional Lenses
DCI W/P 6500K The P3/DCDM color gamut is substantially broader than the ITU 709 gamut for video. Sony projectors support both ITU 709 and P3 color spaces. The projectors differ in power supply, lamps and projected brightness. The SRX-S105 and R105 each incorporate two 1 kilowatt Xenon lamps for a maximum output of 5,000 lumens, with both lamps operating at 100%. - Page 31 To accommodate the full range of SD, HD, computer and Digital Cinema inputs, the projectors have four input slots that accept optional input boards. Optional Input Board LKRI-001 LKRI-002 LKRI 003 LKRI-004 Internal signal transport is accomplished by Low Voltage Differential Signal (LVDS).
- Page 32 (right) operates basic input switching functions. Sony paid special attention to periodic maintenance. Lamp bulbs and lamp houses can be replaced without special jigs or tools. (Of course, appropriate safety equipment should always be worn.) This minimizes downtime during the replacement cycle.

Page 33: A Final Word
While our story has been long and detailed, our conclusions are short and simple. • Sony is in projection for the long haul. We've been doing this for 35 years. And our SXRD 4K projectors are already used in high-profile applications in the commercial, educational, content creation and digital cinema sectors. -
