Design Platform Creates Displays
Having a layer of colored oil operating as an optical shutter, Liquavista’s ColorBright Liquidizer electrowetting design platform makes displays by generating a transparent channel to give selectable views of reflector designs and effects. The tool exhibits defining of segment shapes within the colored oil active area, selective fill, and a “hidden until ON” function to have the display match the color of the product casing until activated. The segmented cells offer reflectance of 40%, a contrast ratio of 6:8, viewing angle of 180°, image transition time of 50 ms, power consumption of 300 µW in a 50 mm diagonal display, and thickness of 0.9 mm. Displays operate using a direct drive segmented scheme with a standard driver IC in a max. active area of 150 mm diagonal and a temperature range from 0°C to 50°C in phones, watches, cameras, DVD players, and automotive applications. Color choices include red, green, blue, black, cyan, yellow, magenta, and purple.
