Electrowetting technology
Last December, for the first time since 1999, Samsung swallowed up another company. She turned out to be the Dutch Liquavista BV, which is engaged in the development of electrowetting technology.
Five years ago, Liquavista seceded from Philips Research Labs and began developing electronic display technology, also known as electrowetting (EW). Electro wetting implies a change in the moisture properties of hydrophobic surfaces using an electric field.
The electrowetting technology works in the modes of light transmission, transparency, reflection and translucency. It allows you to create full-color screens with greatly reduced levels of energy consumption. By purchasing Liquavista, Samsung aims to introduce in the short term innovations in the field of electronic ink and transparent screens.

The use of EW-screens can be a compromise between non-volatile electronic ink and more demanding on the power supply of LCD-panels. Here are some numbers.
- The limiting refresh rate of the image on EW-screens is 70 times (!) Higher than the performance of existing reflective screens (e-ink), which, for example, allows displaying full-color video in bright sunlight, which is still impossible on any commercial product.
“Due to twice the transmittance compared to LCD technology and the ability to control the refresh rate of the image, the power consumption of EW screens can be reduced 10 times (!) Compared to existing panels. At the same time, it is also important that the manufacturing technology of EW-panels is compatible with existing lines of LCD and requires only some modifications.
In the future, the company intends to develop other areas, including the production of translucent, transparent and translucent screens.

Currently, three types of screens have been developed based on the technology:
Liquavistabright - high-performance monochrome reflective screens with video output.
Liquavistacolor - high-performance full-color reflective screens.
Liquavistavivid - high-performance light-transmitting screens, combining two modes: energy-efficient monochrome for viewing in the light and productive full-color with the use of backlight (for use - analog Pixel Qi).
Already in 2011, the technology can be used in commercial products from Samsung: e-books, mobile phones, media players and other mobile devices.
