Field-Sequential PMVA Displays

Field-Sequential (FS) displays let product teams engage end users with a variety of colors directly on the LCD. FS technology achieves different colors per segment by combining an RGB backlight with a specialized IC that drives each segment in sync with red, green, and blue backlight phases. The result is per-segment color from a single passive-matrix LCD, with the segment IC and backlight sequencing handled at the module level.

Because FS displays operate in positive mode by default, they are best suited to indoor applications where ambient light is controlled. All FS designs are custom, allowing the segment artwork, color assignments, and IC programming to be tailored to the host product. When paired with Polytronix's patented PMVA cell — the FS-PMVA configuration — the display combines RGB-backlit multi-color segments with PMVA's deep-black background, wide viewing cone, and enhanced contrast. Internal capacitive touch and conventional touch-panel options can be integrated for complete operator-interface assemblies.

FS-PMVA is the platform of choice for product teams who want a differentiated, multi-color UI on a deep-black background without the cost or driver complexity of a TFT-LCD — premium appliances, smart-home controls, branded audio products, and indoor industrial operator panels are all common targets.
