Caption: 1. Upper layer; 2. Transparent electrode layer; 3. Transparent microcapsules; 4. White pigments with positive charge; 5. Black pigments with load; 6, transparent liquid (oil); 7, electrode pixel layer; 8, substrate; 9, light; 10, white; 11, black.
In order to be easier to understand, we can actually imagine the electronic ink particles as a “capsule”.
Negative black particles and white particles with positive electricity
And we can control the polarity of the current board current. According to the principle of gimmicking in the same sex, the principle of opposite sex, we can choose white or black particles on it, so that the point shows white or black. If the number of black particles and white particles at the same time on it can realize the display of different grayscale at this point.
