Example Embodiment
[0034] The present invention will be further described below in conjunction with specific embodiments:
[0035] Electrowetting is also known as electrowetting, and the present invention is also suitable for ink filling in electrowetting displays.
[0036] In order to prevent the flexible electrowetting display from bending and the ink overturning the wall during the folding process, the pixel wall needs to be raised to a height of 1-100μm, and a better height is 10~70μm.
[0037] Because the voltage is affected by the amount of ink, that is, the more ink in a single pixel cell, the greater the voltage required for opening and closing, so the ink height is preferably 1-10 μm, more preferably 2-5 μm.
[0038] The following specifically introduces the method of soft template method to control ink volume
[0039] 1. Prepare the first template and the second template
[0040] Both the first template and the second template are soft templates. The soft template material can be various hydrophi...
