Silicon X-tal Reflective Display (SXRD) imaging device

The SXRD device used by the SRX-Series projectors is a 1.55-inch* Liquid Crystal on Silicon based imager developed by Sony using cutting-edge manufacturing technology. High-quality, accurate visuals are created using this brilliant imaging device.

4K resolution

Sony SXRD display devices deliver the exceptionally high resolution of 4K (4096 H x 2160 V pixels at 1.896:1 aspect ratio), 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 imager at a narrow pitch of 8.5 micro- metres. These high-density pixels, which are one quarter the size of pixels projected using typical 2K resolution projection systems (2.2 million pixels), provide an amazing picture. Even in multi-screen mode, full HD and 2K resolution per quadrant is possible. The resolution available from the Sony SRX-Series projectors enables a new level of visual projection.

High 1800:1 contrast ratio

The SRX-Series projectors offer a high contrast ratio of more than 1800:1* through the use of Sony’s unique SXRD device. The SXRD imaging device itself achieves a contrast ratio of over 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 ‘Vertically Aligned Liquid Crystal’ system and an extremely thin liquid crystal cell gap.

*The contrast ratio is measured from a screen offering a gain of 1.0.

Vertically Aligned Liquid Crystal 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 imager.

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. However, 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 Vertically Aligned Liquid Crystal system displays black when the electric field is not applied. And because all molecules are in the correct alignment, the polarised light alignment is also optimised. The direct result is a far deeper black level, leading to a high contrast ratio.
