Embodiment 1

[0041] Embodiment 1, Embodiment 2, and Embodiment 3 are devices with two, three, and four-color pixels respectively, in which various inks share an electrolyte solution, and they are not compatible with the electrolyte solution and each other. The arrangement of the electrodes is as follows: there is a common electrode under the electrolytic solution, and there are individual electrodes under each ink. By controlling the voltage of the lower electrode and the common electrode of an ink, the interface force between the electrolyte solution and the ink changes, so that the ink is pressed into the upper display layer by the electrolyte solution, that is, the hollow transparent double spherical layer, to achieve display the goal of. Because the inks are not compatible, each pixel of the present invention can also display the color mixing effect of various inks, that is, two or more inks are squeezed into the display layer at the same time. by Figure 4 For example, the device ca...

Embodiment 4

[0042] Embodiment 4, Embodiment 5, and Embodiment 6 are also two-, three-, and four-color pixel devices respectively. The difference from the first three embodiments is that each ink has a corresponding electrolyte solution. The arrangement of the electrodes is as follows: the unit composed of each ink and the corresponding electrolyte solution has two upper and lower electrodes respectively, and the display of each color ink is realized by controlling the upper and lower voltages of each unit.

Abstract

The invention discloses a method for realizing a full color display via an electric wetting technology, voltage is applied on electrolytic solution and printing ink with needed display colors; and the printing ink applied with voltage is extruded into a hollow transparent layer according to the electric wetting principle. The invention further discloses a device for realizing full color display via the electric wetting technology, according to the method and the device, multiple colors can be displayed on one pixel point, and colors are not mixed, thus a purpose of the full color display can be well achieved.

Description

technical field [0001] The present invention relates to the field of electrowetting display technology, in particular to a method and device for realizing full-color display by using electrowetting technology. Background technique [0002] Electrowetting display is a new display technology emerging in recent years. Simply speaking, electrowetting technology is to control the surface layer of the surrounded liquid by controlling the voltage, resulting in the change of the pixel. figure 1 It is a schematic diagram of the principle of electrowetting technology, such as figure 1 As shown, when no voltage is applied, the colored liquid, namely figure 1 The oil 11 in the medium forms a flat film with the outer layer of the electrode 12 which is impermeable and insulated, and a colored pixel is formed. When a voltage is applied between the electrode 12 and the saline solution 13, the tension of the contact surface between the oil 11 and the outer layer of the electrode 12 will c...
