Syndiant Microdisplay Technology
Syndiant designs and manufactures cutting-edge, all-digital LCOS microdisplay technology powering near-eye devices, ultra-portable projectors, and high-brightness systems. From pioneering WVGA displays to advanced 4K UHD solutions and beyond, Syndiant continuously drives innovation and shapes the future of microdisplay technology.
Field Sequential Color
Field Sequential Color (FSC) technology divides a full-color image into rapid sequences of red, green, and blue color fields. The microdisplay swiftly projects these fields in succession, allowing the human eye to seamlessly blend them into a vibrant, full-color image. Unlike traditional LCD displays, which dedicate separate pixels to each color, FSC achieves higher resolution within a more compact form factor.
Leveraging proven Liquid Crystal on Silicon (LCOS) technology and high-volume semiconductor manufacturing, Syndiant’s all-digital smart panels deliver a large-screen HD+ visual experience in compact handheld and wearable devices.
Single Pulse Drive
High color field rates require high-speed liquid crystals (LC); however, these LC blends typically have very asymmetric rise and fall times. Compared to complex multiple pulse digital schemes, a single pulse technique based on pulse width modulation (PWM) has the advantage of ensured monotonicity, where longer duration pixel drive time equates to a brighter output regardless of liquid crystal switching characteristics.
Small Highly Parallel on-Display SIMD Processing
Syndiant on-display processing efficiently generates a single pulse from encoded pixel values to simultaneously drive every pixel on the display device. Independently controlling millions of pixels while updating at high field rates of field sequential color would be impractical without on-display processing.
To perform the very large number of operations required, Syndiant displays employ a small highly parallel processor with a Single Instruction, Multiple Data (SIMD) stream. A very simple bit-serial processing element (PE) per column of pixels runs the same operation or instruction but with data based on the value of the pixel.
On-die scratch memory buffers pixel data being processed and enables a very fast “context switch” between two colors as they sequence. Memory is constantly reallocated to different pixels based on proprietary algorithms that leverage bit-serial processing to reduce cycles, save power, and minimize on-chip memory requirements.
Q-View
Enabling 4K UHD and beyond, Syndiant’s all-digital Q-View technology brings Ultra High Definition to pico-projectors and mobile near-eye displays.
As displays move to higher resolutions, power consumption tends to increase linearly with pixel count. Since a 4K display has 4x the number of pixels as 1080p, power consumption of the display backplane will also increase by 4x.
Q-View technology requires almost no additional power consumption in the backplane; 4K Q-View has virtually the same power consumption as a native 1080p backplane. Additionally, with Q-View the optical engine can be designed for ¼ resolution, reducing lens design and manufacturing costs.
