Example Embodiment
[0029] Implementation mode 1:
[0030] The invention provides a roll-to-roll color electronic paper manufacturing method, which includes the following steps: 1. Making a drive circuit, a segment circuit or a thin film transistor circuit on a lower roll substrate (flexible glass), and pressing the electronic ink to form an electronic Ink display module; 2. Make color filters on the roll-up substrate (flexible glass); 3. Align the roll-up substrate and the down-roll substrate; use the energy of the laser beam to selectively convert red, green, and blue The color pigment is laser-transferred from the color filter ribbon of the upper roll substrate to the lower roll substrate to form the pixels of the color filter to complete the production of flexible color electronic paper.

[0031] Implementation mode 2:
[0032] The invention provides a roll-to-roll color electronic paper manufacturing method, including the following steps: 1. Making a drive circuit, a segment circuit or a thin film transistor circuit on a lower roll substrate (plastic), and pressing the electronic ink to form the electronic ink Display module; 2. Make color filters on the roll-up substrate (plastic); 3. Align the roll-up substrate and the down-roll substrate; use laser beam energy to selectively add red, green, and blue pigments The color filter ribbon from the upper roll substrate is laser transferred to the lower roll substrate to form the pixels of the color filter to complete the production of flexible color electronic paper.

[0033] Implementation mode 3:
[0034] The invention provides a roll-to-roll color electronic paper manufacturing method, including the following steps: 1. Making a drive circuit, a segment circuit or a thin film transistor circuit on a lower roll substrate (metal sheet), and pressing the electronic ink to form an electronic Ink display module; 2. Make color filters on the roll-up substrate (metal foil); 3. Align the roll-up substrate and the down-roll substrate; use the energy of the laser beam to selectively convert red, green, and blue The color pigments are laser-transferred from the color filter ribbon of the upper roll substrate to the lower roll substrate to form the pixels of the color filter to complete the production of flexible color electronic paper.
