E ink display controllers – One technology, two different solutions

EPDs (Electronic Paper Displays ) have been on the global market for many years, however, the scope of their applications has so far been limited. Currently, thanks to developments in technology, the range of possible applications has been expanded. Due to the characteristic, highly favorable features and increasingly lower prices, e-paper is gaining popularity. In an effort to make this technology more accessible to customers, Unisystem recently added electronic paper to its offerings. However, it should be noted that in order to take full advantage of EPD technology, you also need a matching controller. The variety of applications has led to two types of dedicated controllers on the market, which are also included in Unisystem’s product range.

MpicoSys Controller

The first is a controller from MpicoSys, which allows E Ink’s e-paper displays to be used in the same way as other electronic displays. The concept is based on energy-efficient microcontrollers, on the basis of which controllers have been developed that allow precise control of the screen while consuming low power. The controller communicates with the module using the SPI interface. Such a solution makes it possible to significantly reduce the cost of the controller, which positively affects the price of the final application. However, the user should be aware that this type of controller requires its own programmed microcontroller to communicate and send images over SPI. MpicoSys has also prepared a dedicated USB SPI adapter that makes it easy to connect the controller to any computer.

Visionect controller

A completely different solution was designed by Visionect. In creating controllers for the e-paper, Visionect aimed to make the operation and configuration of the display as simple as possible. The final result was a controller in which the software is so comprehensive that, together with the EPD display, it effectively forms a complete wireless network device.

The application does not require advanced engineering knowledge. Visionect controllers are based on Epson ASICs developed for E Ink displays. The module is managed using a specially developed platform called VSS (Visionect Software Suite). It is a complete web-based GUI with which you can, among other things. easily control and change the displayed content or view power consumption data. VSS also has a dedicated API, so you can integrate it into your own application.

New suppliers, new opportunities

The new profile in Unisystem’s offering is related to a recent partnership with three companies related to e-paper technology (displays and controllers) – E Ink, MpicoSys and Visionect. Company E Ink is a pioneer and world leader in the design and manufacture of EPD displays, while the companies MpicoSys and Visionect , design and supply the corresponding controllers for E Ink displays. Unisystem’s cooperation with these three entities enables us to offer customers a comprehensive EPD technology service.
