The Ynvisible Display is an e-paper technology, a so-called Electrochromic Display ("ECD"), based on organic electrochromic polymers. It is categorized as a reflective display - meaning that it reflects ambient light instead of using a backlight. The displays are screen-printed on a plastic substrate, which makes the displays very thin and flexible.

Ynvisible's e-paper displays have the lowest energy 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.
Ynvisible rarely creates standard display components. Our philosophy is that each product requires a unique display for an ultimate user experience.
The printability of the displays ensures that customers can attain a degree of customization that is not available from alternative display technologies. This creates an attractive appearance that is highly appreciated by both product designers and end-users.
Display segments can be designed in essentially any shape and form. Letters, symbols, numbers, and graphics elements are all possible.
Color filters and other static graphic elements can easily be printed on top of the display. The graphic overlay is commonly used to add graphics that should always be visible and complement the dynamic display segments.
Most conventional displays are bulky rectangle shapes. This is not the case for Ynvisible Displays. Essentially any cut-out shape is possible, whatever fits your product the best.
Ynvisible was founded in Lisbon, Portugal, in 2010 with the strong ambition and vision to turn static print into interactive surfaces using innovative electrochromic technology. Today, Ynvisible has offices in Canada, Portugal, Sweden, and Germany, and is traded on the Toronto Stock Exchange Venture Board, Frankfurt Stock Exchange, and OTCQB USA Stock Exchange.
Ynvisible is disrupting the low-cost and ultra-low-power display industry thanks to the latest advantages in sustainable electronics and roll-to-roll printing production. Ynvisible’s printed e-paper displays are ideal for low-power and cost-sensitive applications, such as digital signage, smart monitoring label, authenticity and security, and retail labels and signage.
Ynvisible has the experience, know-how, and intellectual property in electrochromic materials, inks, and systems, and offers a mix of services, materials, and technology to brand owners developing smart objects and IoT products.
E-paper, or electronic paper, is an ultra low power, reflective display technology. There are different e-paper technologies, such as electrochromic, electrophoretic, and electrowetting.
Ynvisible is developing and manufacturing an electrochromic e-paper display technology using sheet-to-sheet and roll-to-roll printed electronics manufacturing processes. Printing means highly scalable, low-cost, and customizable. Ynvisible's e-paper displays are mainly so-called segmented displays and are suitable for basic human-machine interfaces, such as digits, icons, and indicators, and are replacing other expensive and power-hungry display technologies.

No. The Ynvisible display and E Ink display both belong to the e-paper display family, but are fundamentally different technologies. They both share the same principle of being reflective display technologies, ultra-low power, and mimics the appearance of ink on paper. Displays from E Ink are electrophoretic technology while Ynvisible’s displays are based on organic electrochromic materials. Ynvisible's main focus is segmented displays, whereas E ink is mainly offering pixel displays.
Ynvisible's displays have the lowest power consumption on the market for many use-cases. For static usage (when the display maintains the same image) the display consumes a maximum of 1,73µW 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 = 1,67 + 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 recommended operating voltage for Ynvisible's standard e-paper displays is ±1.5V.
Ynvisible’s technology is very simple to drive. This is one of the key differentiators to other e-paper technologies. The GPIOs in most MCUs can drive the displays with a minimal requirement of additional components. Apply a positive voltage across the display segment to turn on and short circuit, or apply a negative voltage to turn off. The voltage should only be applied when the display switches or is being refreshed.

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 250 milliseconds are required to activate a 4mm2 display segment using a 1.5V drive protocol.
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. Read more about color options.
Not fully bistable displays, we call them semi-bistable.
The standard displays have a retention time of approximately 1 minute to 15 minutes before a small refresh pulse is required. However, we can optimize the displays for shorter or longer image memory time with small modifications to the devices. In this way, we can achieve retention times ranging from a few seconds up to a few days.
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.
Electrochromic displays from Ynvisible are based 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.
Yes, but these devices are not yet mass-producible. Ynvisible’s main focus is direct-driven segmented displays.
Ynvisible has the experience, know-how, and intellectual property in printed electronics, electrochromic materials, inks, and systems, and offers a mix of services, materials, and technology.
Ynvisible offers its services throughout the entire process; from R&D projects and the prototyping phase, to mass production printed electrochromic displays and product soutions.
Yes, making custom-designed displays, tailored to specific clients and use-cases is our core business. We rarely make generic standard displays since our experience is that each client requires a unique solution. We have a standardized fixed-fee offer to make custom-designed prototypes.
