Making a more compact, higher resolution portable projector possible
Sony Semiconductor Solutions Corporation
Tokyo, JapanâSony Corporation today announced the upcoming release of the SXRD™ (Silicon X-Tal (crystal) Reflective Display) SXRD241A, the world's smallest*1 reflective display device in full HD resolution designed for portable projectors, and the CXD3554GG, a dedicated drive LSI equipped with a high-definition signal processing function.

The market for portable projectors, which are used to project a variety of content such as videos and still images while at home or out of the house, is growing recently, and their use case is expected to expand along with future advances in more compact design and higher resolution.
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 seamless 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.
