Using two micromachined mirrors to create world's smallest projection engine
STMicroelectronics is working with bTendo of Israel to jointly develop the world’s smallest Pico Projector for smart phones and other portable consumer-electronics devices. The solution is based on bTendo’s Scanning Laser Projection engine technology and ST’s MEMS (Micro-Electro Mechanical Systems) expertise, video processing know-how and semiconductor process technology.
Less than 2.5cm3 in volume and below 6mm high, the jointly developed embedded projector solution will offer a focus free, vivid colour, sharp and crisp image, superior to current pico projection solutions, says ST. With two MEMS-based micro-mirror-actuation devices within the system’s optical engine and an advanced video-processing chip, the engine is optimized for smart phones, offering low power consumption and built-in support for MIPI (Mobile Industry Processor Interface) to ensure swift and easy integration.
“People want to share their media with others and enjoy the option of expanding their display even for their own personal viewing,” said Benedetto Vigna, Group Vice President and General Manager, MEMS, Sensor and High-Performance Analog Division at ST. “ST selected bTendo’s technology due to its small size, low power and focus-free features, which are all critical for embedded projection modules. ST has a long history in the development of innovative technologies and this joint cooperation will further extend our MEMS sensor expertise, while also complementing and reinforcing our leadership in MEMS gyroscopes and accelerometers for advanced user interfaces."
“We are very excited to collaborate with STMicroelectronics, the world leader in MEMS technologies for mobile handsets, to bring to the market our cutting-edge technology for embedded Pico Projectors,” said Dana Gross, CEO of bTendo Ltd. “ST’s best-in-class semiconductor process technology and design capabilities will enable a cost-effective, low-power solution perfect for personal consumer devices.”
