Abstract— Iridigm has produced the first color MEMS‐based reflective display. With dimensions of 240 × 160 pixels at 100 dpi, it exhibits good contrast and high brightness. Response times of 35 μsec have been achieved at exceptionally low power consumption, and there is no active matrix. The status of this technology is discussed.

QUALCOMM has developed and transferred to manufacturing iMoD™ displays, a MEMS-based reflective display technology. The iMoD array architecture allows for development at wafer scale, yet easily scales up to enable fabrication on flat-panel display (FPD) lines. In this paper, we will describe the device operation, process flow and fabrication, technology transfer issues, and display performance.

Iridigm has produced the first color MEMS based reflective display. With dimensions of 240 × 160 pixels at 100 dpi, it exhibits good contrast and high brightness. Response times of 35 microseconds have been achieved at exceptionally low power consumption, and there is no active matrix. The status of this technology will be discussed.

A key issue for the optimization of subpixel color tiles for mobile displays is to maximize the image quality, often defined in terms of brightness or reflectance, and color saturation, while minimizing display power consumption. for the mirasol™ display based on MEMS technology, the RGBY quad is found to be a structure that achieves a balance between reflectance and color saturation. Simulation results based upon demonstration devices are presented with discussions about proper image quality metrics for mobile displays.
