SONY SRX 4K PROJECTORS
Responding to the ever-increasing demand for highly sophisticated visuals, Sony launched a series of SXRD™ ultra-high resolution projectors the SRX-T110/SRX-T105 and the SRX-T420
Once launched, these projectors rapidly acquired a great reputation with many customers due to their outstanding picture quality and stunning performance. Now, Sony is proud to introduce the next generation of SXRD 4K projectors: the SRX series, advanced projectors designed to meet the evolving needs for ultimate picture quality. The SRX series are equipped with three Silicon X-tal (crystal) Reflective Display (SXRD) devices and deliver an amazing resolution of 4096 x 2160 pixels (H x V) - more than four times the resolution of consumer HDTV (1920 x 1080). This high-resolution capability allows 2K (2048 x 1080) images to be displayed simultaneously in four quadrants or in a twin “side by side” display. The projectors also offer a contrast ratio of 2500-3000:1. In addition, the SRX-T110 provides a high brightness of 11,000 lumens, while the SRX-T420 offers a brightness of 21,000 lumens. The use of twin Xenon lamps, combined with multiple gamma curves of 2.2, 2.6, and user-defined values, means they offer pure, high-quality color tonal reproduction. Furthermore, the SRX series offer very quiet operation, thanks to an intelligent cooling fan system. Sony SXRD 4K projectors are the ultimate tool for projecting images in a range of applications such as command & control, simulation, computer visualization, planetarium and museum exhibition, and much more.
Silicon X-tal Reflective Display (SXRD) Device
The SXRD device used by the SRX series are a 1.55-inch Liquid Crystal on Siliconbased display device developed by Sony using cutting-edge manufacturing technology. Highquality, accurate visuals are created using this brilliant display device.
High Resolution 4K
Sony SXRD display devices deliver the exceptionally high resolution of 4K x 2K (4096 x 2160, 17:9 widescreen format), more than four times as many pixels as Full HDTV (1920 x 1080, 16:9 wide screen format). The SXRD device helps to achieve this resolution by incorporating nearly 8.85 million pixels per device at a narrow pitch of 8.5 micrometers. These high-density pixels, which are one quarter the size of pixels projected using typical 2K x 1K resolution projection systems (2.2 million pixels), provide an amazing picture. Even in multi-screen mode, full 2K resolution per quadrant can be achieved. The resolution available from the Sony SRX series enables a new level of visual projection.
High Contrast Ratio
The SRX series offer a high contrast ratio of 2500-3000:1 through the use of Sony’s unique SXRD device. The SXRD device itself achieves a contrast ratio of 4000:1. This stunning picture quality makes the projectors ideal for applications in which dynamic range is essential. The high contrast ratio has been achieved through two key technologies - the exclusive ‘normally black mode’ system and an extremely thin liquid crystal cell gap.
‘Normally Black Mode’ System
In every type of projector system, displaying absolute black is a major issue in order 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 device. All Liquid Crystal Display (LCD) devices control the amount of light to be projected by applying an electric field to the liquid crystal gap. In typical LCD devices, 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 but, when displaying dark images, light may tend to leak from the LCD device, since the molecules near the surface are less accurately controlled. This results in a creamy black instead of a deep black. The SXRD device 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.
Thin Liquid Crystal Cell Gap
Another important factor allowing for the high contrast of the SRX series are the SXRD device’s ultra thin cell gap of less than 2 micrometers. With conventional ‘vertically aligned liquid crystal’ systems, a thin cell gap could not be achieved. Sony has overcome this difficulty through the use of innovative planarization technology in the silicon backplane structure and an advanced silicon wafer-based assembly process. The SXRD device also adopts a structure that does not use “spacers”. These are columns found in conventional reflective liquid crystal devices to maintain a constant gap between the liquid cell floor and the top of the device. Spacers tend to both scatter and reflect light, which can impair high contrast pictures. In the spacer-less SXRD device, these artifacts are no longer seen.
Short Response Time
The thin cell gap structure in SXRD devices also contributes to an ultra-fast response time of 2.5 milliseconds (for both rise and fall). The SXRD device reacts promptly to an instantaneous change of picture content, enabling SXRD-based projectors to display smoothly. Consequently, the SRX series virtually eliminate motion blur; a particularly significant benefit for visuals that include fast-moving objects.
Reliable Display Device
The SRX series use high-power, bright lamps. As a result, special attention has been paid to the reliability of the SXRD device. The inorganic materials utilized for the alignment layer of the SXRD device are resistant to deterioration or deformities that could occur due to the intense heat and light generated by the powerful twin lamp system.
Super high purity color reduction
Xenon Lamp Provides Highly Bright and Pure Light Source SRX-T110 provides a high brightness of 11,000 lumens by employing two 2 kW Xenon lamps, while the SRX-T420 offers a brightness of 21,000 lumens by using two 1 kW Xenon lamps. The Xenon lamps utilized by the SRX series achieve a wide color range by dispersing a very flat and wide light spectrum.
The SRX series feature a CSC function to help users easily adjust the projector’s color space to that defined by the ITU*-R BT.709-3 standards for digital HDTV studio color space, the DCDM (Digital Cinema Distribution Master) color space, or the Adobe RGB color space.
The target color gamut parameters satisfying the ITU-R BT. 709-3 standards, or DCDM or Adobe RGB specifications are automatically calculated from settings on the supplied SRX Controller software, and then applied to the projector. The internal test generator simplifies adjustment and lets the operator align the projector in minutes. White point and color primary points can be aligned to either of these standards or to the customer’s application needs. 12-bit SXRD Panel Driver
The SRX series utilize a 12-bit SXRD panel driver that reproduces extremely naturallooking images. This eliminates quantizing and edge errors that take away from the real resolution that these projectors can achieve.
Gamma Curve Selection
The SRX series provides three preset gamma curve values. Users can select an optimum value from 2.2, 2.6, or user-defined values according to the desired gray scale.
