(Summary description)What is electrophoresis technology? Literally means "swimming at a certain voltage", and the display works by moving electric ions immersed in a transparent or colored liquid, that is, by flipping or flowing fine particles to brighten or darken pixels , and can be fabricated on glass, metal or plastic substrates. The specific technique is that titanium dioxide particles with a diameter of about 1mm are dispersed in hydrocarbon oil, black dye, surfactant and charge control agent to charge the particles are also added to the hydrocarbon oil; this mixture is placed in two blocks Between parallel conductive plates with a distance of 10-100 mm, when a voltage is applied to the two conductive plates, these particles will migrate from the thin plate where they are to the oppositely charged thin plate in an electrophoretic manner. When the particles are on the front (display side) of the display, the display is white because light is scattered back to the reader by the titanium dioxide particles; when the particles are on the back of the display, the display is black because the color dyes absorb the incoming light . An image can be formed by dividing the electrodes on the back into tiny picture elements (pixels) by applying the appropriate voltage to each area of ​​the display to create a pattern of reflective and absorbing regions. Electrophoresis has several advantages. One is low energy consumption. Thanks to the bistability, the image remains on the display for days or months after the power is turned off. Second, the displays produced by electrophoretic technology are reflective, so they have good sunlight readability, and can also be combined with front or side light for use in dark environments. The third is the potential for low production costs, as the technology does not require strict packaging and is feasible with solution processing techniques such as printing. Fourth, electrophoretic displays feature flexible form factors, allowing them to be fabricated on plastic, metal or glass surfaces, so it is the best choice for flexible display technology.
