Following the invention of e-book readers and electronic dictionaries, the display technology
market lately saw the introduction and promotion of "electronic paper" as the newest
groundbreaking development in displaying graphics or text.
A clear definition of electronic paper is not easy; however it can be said that the advantages both of
normal paper and other display technologies are taken and combined into one extraordinary
The following describe the basic requirements and features of electronic paper that guarantee customer
satisfaction and a successful marketing.
- comfortable readability and good contrast ratio
- thickness similar to normal paper
- easy to carry (i.e. in a portable device)
- long run-time because of low power consumption (electric power is only needed to change the
- active display even without power supply
Basic principle of electronic paper
So how are these features realized in reality? Looking at the basic principles can help
Just like in a liquid crystal display (LCD), a fluid containing certain particles is inserted
between two glass substrates. If an electric field is applied to the electrodes on the glass
substrates, the charged particles in the fluid change their orientation or position. By this,
a certain image pattern can be displayed.
Electronic paper and screen-printing
To save time and costs, many production steps durint the manufacturing of electronic paper
can be automated, i.e. with screen-printing.
Especially Micro-tec screen-printing machines are highly useful for processing large substrate
quantities while combining high precision with best production results: regardless of paste type
and viscosity, printing pattern, substrate type and general printing process, Micro-tec screen-printers
can help you achieve a stable automated production process (i.e. in connection with the electrophoresis
technique used in electronic paper.)
Exemplary applications for screen-printing are indicated in red in the following illustrations.
The following machines are recommended for screen-printing of electronic paper. They were especially designed
for highest precision, compact footprint, high through-put rates and easy usability.
