Sony today announced the upcoming release of the SXRD (Silicon X-Tal (crystal) Reflective Display) SXRD241A, which is said to be the world's smallest reflective display device in full HD resolution designed for portable projectors.
Sony also announced the CXD3554GG, a dedicated drive LSI equipped with a high-definition signal processing function.
The SXRD241A utilizes Sony's original fine pixel pitch technology to reduce the pixel pitch, resulting in full HD resolution on a 0.37-type chip. Generally, when narrowing the pixel pitch, image quality deteriorates due to light leakage into the semiconductor element under the pixel electrode, but Sony added light shielding layers and optimized the pixel structure to achieve significantly improved light shielding function. Sony also employed a new Field-sequential color technique that sequentially switches the RGB light sources at high speed and drives SXRD241A at the appropriate time to deliver full color display on a single panel. Moreover, original SXRD technologies developed for 4K high-end home projectors were adapted to achieve high resolution, high contrast, and high brightness.
The CXD3554GG uses an original high-definition signal processing function to maximize the properties of the SXRD display device. It is equipped with a new geometric compensation function which ensures distortion free images even on curved surfaces, as well as an edge blending function which does away with image seams when multiple projectors are combined together, creating a single image. All of these functions based on the LSI that will make portable projectors even more usable. By adapting SXRD241A together with CXD3554GG, it is possible to realize high-definition portable projectors even with compact sizes.
Shipments of both units will start next month. These portable projectors will have the ability to provide a distortion-free picture even on curved surfaces. This means you could whip out your device anywhere and enjoy an almost clear picture, no matter what background you're projecting it onto.
