The product and its strengths
Etulipa EWD displays
What is so special about a display based on Etulipa EWD technology?
A display based on Etulipa’s Electro Wetting Display (EWD) technology is a reflective display, an ePaper display. Like all ePaper displays, Etulipa’s full-color displays cause almost no light pollution and are extremely energy efficient.
The key differences with other ePaper technologies are EWD’s suitability for full color, video, and outdoor use. A display based on the EWD technology has all the advantages of paper, and in addition, is digital.
Because of its low power consumption, Etulipa full color displays can run forever on solar panels and a battery.
Why should I choose a display based on Etulipa EWD technology out of all the other ePaper possibilities?
The Etulipa EWD technology is by its nature suitable for full color, video, and outdoor use. Etulipa’s EWD displays are all weatherproof with a very wide operating temperature range of -30°C to +65°C.
Power consumption
What is the power consumption of an Etulipa full-color EW display?
The display itself uses approximately 5 Watts per square meter. There is some extra power needed for the backlight in the evening. Typical nighttime power consumption with backlight will be 9 Watts per square meter. Tens of times less than the power consumption of a LED screen. The power can be provided by a solar panel combined with a battery.
Does a display based on Etulipa EWD technology use extra power in bright sunlight?
No, because of the reflective characteristics, the screen does not need to fight against the sun. Even in bright sunlight, the display is perfectly readable without extra power consumption.
How to power an Etulipa full-color EW-display?
With a battery and a solar panel.
Does a display based on Etulipa EWD technology use extra power in the evening?
Only when the built-in backlight is used.
Light pollution
Does an Etulipa EWD display cause any light pollution?
The natural environmental lighting makes the content visible, just like paper. There is no artificial lighting needed during the day and therefore no light pollution.
What about light pollution in the evening?
During darkness, some additional lighting is needed to make the content visible.
Etulipa’s first full-color product
What is the size of an Etulipa full-color EW-display?
An Etulipa full color EW-Display has a modular construction and can be extended in size upon requirement. The display is built up from panels.
What is the size of an Etulipa full-color EW-panel?
An Etulipa full color EW-panel is 45cm W x 43,5cm H (edge included)
Resolution: 44 W x 42 H pixels
What is the pixel size of Etulipa’s full color EWD?
10mm
What is the weight of an Etulipa full color EWD panel
The weight of an Etulipa Full color EW-panel with 6 tiles is 6,5 kg.
Can an Etulipa full color EWD panel or display show video?
Etulipa’s EW Display can display high-speed videos, gifs, and animations.
What is the maximum luminance of the screen?
In full sunlight with an approximate average reflection of 0.5 the equivalent luminance is 15,000 nits.
What is the viewing angle?
The viewing angle is approximately 140 degrees horizontal and vertical.
How much heat produces a screen based on Etulipa EWD technology?
There is no heat production since the power consumption is only 5 Watts per square meter.
Does a screen based on Etulipa EWD technology produce any noise?
No.
Readability
Is a reflective display based on EWD technology viewable in bright sunshine?
Yes, it has excellent viewability in the sun. Because of the reflective characteristics, the display does not have to fight against the sun, it uses the sunlight. The display is perfectly readable in bright sunlight without additional power consumption.
Is a reflective display based on EWD technology viewable in the evening?
It works just like paper. Because of its high contrast, the display is viewable if there is some ambient light. In the darkness, a backlight can be turned on.
Reliability
What is the operating temperature range?
Operation in an environment temperature range between -30°C to +65°C.
What is the operating lifetime?
Etulipa targets to reach the market standard of > 100.000 hours.
Are the colors solar-resistant?
UV filters are used to prevent color fading. The panels comply with the requirements in the solar resistance test program MIL-STD-810G.
Buy
Is Etulipa a display manufacturer?
Momentarily, Etulipa designs, develops, produces, and sells panels or displays based on its innovative EWD technology and brings its new reflective display to various markets.

Technology background
ePaper
Is a display based on Etulipa EWD technology an ePaper display?
The Electro Wetting Display (EWD) technology from Etulipa, is a type of ePaper technology. Many ePaper technologies exist, each with its strengths and weaknesses.
Etulipa’s ePaper technology has been developed because of the need for reflective displays that can display full color video content.
The displays are made up of cells containing three layers of colored oil (Cyan, Magenta, and Yellow), which mimics the method used in color printing. EWD technology relies on the surface tension of the liquids and uses a low, applied voltage to cause the oil to spread or contract. Depending on the color required, the different oils can be switched on or off, forming various combinations. The resulting colors are much brighter than in any other ePaper display.
Above, an image of three layers with EWD pixels. EWD pixels with a pixel size of 10mm are made up of 400 cells containing Cyan, Magenta, or Yellow oil. The light is reflected from the white reflector behind the cells.
Color
Etulipa uses CMY colors instead of RGB colors. Why?
In a reflective display, the RGB color filters can pass maximally 1/3 of the light, which yields very dull colors (see image below). In CMY the color is created by three vertically stacked layers of oil with respectively Cyan, Magenta, and Yellow. Each layer can be switched off and on. The entire surface area reflects the appropriate component of the light resulting in highly saturated colors with great contrast.
What colors are possible with the Etulipa EWD panels?
The EWD colors are like those seen in printed media. Commercial printing presses print with Cyan, Magenta, and Yellow ink.
Video and images
Can I show videos on an Etulipa EWD-based display?
Etulipa’s ePaper technology has the capability to display full color video content.
What is the refresh rate of Etulipa EWD panels?
80 Hz.
Future Developments
Will a smaller pixel size be available in the future?
Yes, displays with a pixel size of 2,5 mm are under development
Can the seams be made invisible in the future?
Today, seems are approximately less than a 10mm pixel wide. Smaller seams are under development.
Miscellaneous
Where can I see the Etulipa full-color EW-Display?
A full-color panel can be viewed during the SID Display Week 2023 at the Los Angeles Conference Center. A permanent display can be viewed at any time at the High Tech Campus in Eindhoven.
