Leading Edge LCD Products: Ultrahigh Resolution "SXRD" Full HD Reflective LCD and Ultrabright "BrightEra" SXGA+/XGA Transmissive LCD

SXRD211, LCX079A/LCX083A

Sony is now releasing two new LCD products: the 0.61-type SXRD*1, which is the world's smallest full HD LCD, and the 0.79-type BrightEra*2 which includes both an inorganic alignment film, which Sony led the industry in developing as an HTPS technology*3, as well as a new LCD device technology. The SXRD is a full HD reflective microdisplay for next generation AV projectors. It achieves the extremely high contrast ratio of 5000:1 and a high reflective efficiency despite a reduced pixel size. The BrightEra is a transmissive microdisplay that deploys both Sony's unique inorganic alignment film developed for the SXRD and a new LCD device technology to achieve the industry's highest levels of brightness and efficiency. Sony is committed to leading the industry in the supply of microdisplay devices for high-performance projectors.

Inorganic Alignment Film and New LCD Technologies

Sony independently developed the inorganic alignment film and a new LCD device technology used in both these devices to achieve the SXRD's high picture quality and resistance to light. Compared to the earlier organic alignment film, molecular coupling in the alignment film has been increased significantly and absorption of short wavelength light has been reduced. This increases the device's resistance

to damage by light and makes it possible to use powerful illumination. Furthermore, the physical alignment processing provided by rubbing in earlier devices is no longer required, allowing an extremely even image to be acquired. At the same time, the normally black mode LCD device technology results in an ideal LCD array, and an even tighter black can be achieved.


While 720p has become the current mainstream in the AV market, there is also rapid progress in the move to full HD (1080p) in such areas as terrestrial digital TV, camcorders, and especially in Blu-ray recorders. The device that will bring this resolution to projectors is the SXRD211 0.61-type full HD reflective microdisplay. Sony's leading edge fine fabrication technology has reached the industry's finest pixel pitch of 7 µm and made it possible to achieve the increased pixel count necessary for full HD in a 0.61-type device. Furthermore, a new reflective film structure achieves the high reflectivity of 74%. By optimizing the inorganic alignment film and the new LCD device technology to this structure, Sony was able to achieve the industry's highest level of high-contrast performance: a contrast of 5000:1.






[SXRD] We hope you will enjoy the large-screen movie experience provided by Sony's ultrahigh definition film-like high picture quality that is not possible on direct viewing displays such as LCD and PDP. This picture quality is now provided by projectors that include the world's smallest full high definition SXRD. [BrightEra] Wouldn't you like to be relieved of the stress of turning lights on and off in conference rooms by projectors that include BrightEra, which achieves the industry's highest level of projector brightness based on unique Sony technologies?

ket growth in the 3000 to 5000 lm class products is expected. In particular, devices in the 4000 to 5000 lm class are capable of providing enough screen contrast without turning off the room lights in conference rooms with 100inch class screens. This is a critical product zone that can project clear video images even under bright ambient lighting conditions. This brightness range could only be achieved with large-scale devices in the 0.99 to 1.3-type class in projectors based on devices that used the earlier organic alignment film. By deploying the inorganic alignment film technology in the BrightEra devices of this release, and by inheriting the features of this technology, namely high light resistance and high picture quality, it becomes possible to use even brighter light sources. Thus it is now possible to create a reasonable projector with extremely high brightness in excess of 4000 lm by using the miniature 0.79-type LCX079A and LCX083A devices. In addition, Sony also succeeded in reducing the area of the TFT elements by about 70%, which also contributes to even higher brightness due to the higher pixel aperture ratio. Not only has brightness been improved, but adoption of the normally black mode LCD device achieves a contrast about three times higher than that of earlier LCDs.
