Printed electrochromic displays can be used in a variety of applications, ranging from luxury products to single-use devices. The displays are extremely versatile in terms of design freedom, form factor, and usage scenarios.

Most common applications include medical devices, smart packages and containers, logistics and cold chain monitoring devices, consumer electronics, smart cards and smart labels, wearable devices and patches, and fast-moving consumer goods.

No. The printed display and E-Ink display are fundamentally different technologies. They both share the same principle of being reflective display technologies, meaning that they reflect ambient light and that no backlight is needed. Displays from E-Ink are electrophoretic technology while our displays are based on organic electrochromic materials.

Electrochromic displays are based upon screen-printable electrochromic polymers. The term “Electrochromism” refers to the phenomenon whereby a material undergoes a physical color change in response to an electrical stimulus. Electrochromic displays are produced by printing thin layers of these materials with high-performance electrolytes into a flexible “electrochromic stack.” When a voltage is applied to the electrochromic material in the presence of the electrolyte, it undergoes chemical oxidation and reduction. These processes are associated with a color change which can be finely tuned. The final displays are as thin as 200 µm, and flexible enough to curve around a pencil.

The refresh speed, or update speed, will vary depending on the size of the display segment. Large display segments are slower than small display segments. Approximately 200 milliseconds are required to activate a 4mm2 display segment using a 3V drive protocol.

Our displays have the lowest power consumption on the market for most use cases. For static usage (when the display maintains the same image) the display consumes a maximum of 0,28µW per cm2 segment area. For dynamic usage, the power consumption depends on the number of display updates per day according to the formula below.

P = 0,28 + 0,01 × n µW/cm2

n is the number of full display updates per day

One square centimeter active display area requires approximately 1 mJ to activate.

The contrast ratio is normally ≥ 1:3.

Ynvisible’s displays are more similar to printed graphics rather than conventional electronics displays. Color Difference (ΔE) is a more suitable metric to express the difference between the display segment in the off/neutral state and the on/activated state. The Color Difference value will change depending on the specific display color, however, our most common Gray<>Blue display has a typical Color Difference value (ΔE) of 30.

Our displays are available in multiple colors, but they are monochrome since the colors needs to be pre-defined. We can not do full color displays, such as RGB or CMY displays, but it is possible to make multiple colors in the same display in a side-by-side arrangement.

We offer displays in a wide range of colors and can customize tones to match your brand. Our standard colors are Grey, Red, Green, Magenta and Yellow. The grey color offers the best readability.
