Purpose and goal
The goal of the project was to demonstrate the viability of screen printing a passive matrix display in large volumes. The goal has been achieved and a demonstrator has been developed showing that the technology has great market potential.
Expected results and effects
This project has led to great progress for passive matrix addressing of printed displays. The possibility to achieve this in a screen printing process and by combining the right types of materials in the pixel structure without using any active or passive components is unique and will facilitate commercialization.
Planned approach and implementation
The following steps were planned: 1. Development of pixels with a sufficient threshold voltage (RISE Acreo AB) 2. Development of printing process (RISE Acreo AB + Rdot AB) 3. Printing of segmented passive matrix addressed display (RISE Acreo AB) 4. Development of driver electronics (Rdot AB) 5. Demonstration of a passive matrix display (Rdot AB) Generally, the project has been implemented according to plan.
