Demand for business front projectors is expanding yearly as use for corporate business presentations increases and the education market adopts information technology.
In addition, the trend towards higher projection brightness in teleconferencing rooms, open spaces where meetings are held, classrooms and other bright environments is continuing, and the 3,000 to 5,000 lm class high-brightness segments of these markets are expected to grow in the future.
In particular, devices in the 4,000 to 5,000 lm class are capable of providing sufficient screen contrast with a 100-inch class screen even without turning off the room lights, making this a critical brightness zone that can project clear video images even under bright ambient lighting conditions.
Earlier projectors could only achieve this brightness range with large-scale devices in the 0.99 to 1.3-type class that use conventional organic alignment films.
The inorganic alignment film employed in the new “BrightEra” panels is a core technology that features a high resistance to damage by light, allowing use of even brighter light sources. Furthermore, the deployment of various high-brightness technologies makes it possible to simultaneously reduce the device size. This has enabled development of a 0.79-type device that can be used in a portable projector that achieves the high brightness of 4,000 lm or higher.

Sony intends to deploy this “BrightEra” light resistance technology to provide a diverse lineup of ultrabright microdisplays in the future, including devices that support various resolutions at 3,000 lm and higher, and also medium and large-sized devices that support the ultra-high brightness of 5,000 to 10,000 lm or higher.
