The electric control deformation microstructure can be formed by using a polyvinyl chloride (PVC) gel film layer to form a micro-cup structure arranged in a matrix, the PVC gel film layer can be an independent micro-structure layer and can also be attached to a base material, electrodes are arranged in the micro-cup structure, driving voltage can be applied to two ends of each electrode, the shape of the micro-cup structure is changed under the action of the voltage, the electronic paper structure comprises four layers, as shown in figure 1, the four layers are respectively a base material layer, a control layer, a display layer and a protective layer, and an electric control deformation microstructure is arranged between the control layer and the display layer, namely, a micro-cup structure array.
Firstly, polyvinyl chloride (PVC) powder and dibutyl adipate (DBA) are mixed into jelly-shaped soft PVC gel according to the mass ratio of 1: 9, and the PVC gel is coated on an IPS electrode in a spinning mode to prepare a PVC gel micro-cup array structure. These microcups are simple and compact in structure, and do not twist due to the effect of gravity when placed vertically, since the film is firmly adhered to the substrate.
The substrate layer 1 of the electronic paper structure is an ITO film with PET as a substrate or glass plated with an ITO layer.
The control layer 2 is a microcup structure made of PVC gel, liquid pigment is distributed in each microcup to form a display layer 3, and a leuco matrix 4 is distributed above the microcups (namely the lower surface of the protective layer 5). The color matrix is an opaque region that blocks the pigment from view below the color matrix, which may be white, black, or other opaque color.
The control layer of the electronic paper structure is composed of an electric control microstructure, and under the control of voltage, the micro-cup structure deforms to different degrees along with the change of an electric field, so that the gray value electric control change of pixels of the electronic paper is formed, and the aim of displaying gray images is fulfilled. The electric control microstructure is formed by etching a micro conductive electrode structure on the upper surface of the substrate layer and the lower surface ITO layer of the protective layer and applying different voltages to form a driving electric field.

Under the action of the driving electric field of the microcup structure, the PVC gel is deformed. The microcups control local deformation of the layer 2, which changes the internal structure of the microcups, thus driving the distribution of the liquid pigment to change, the liquid pigment is uniformly distributed in the microcups in the case of displaying the gray state 1 as shown in fig. 2. In the case of gray state 2 as shown in fig. 3, the liquid pigment is pushed in the direction of the leuco matrix, the area far from the leuco matrix becomes thinner or even completely free of pigment, and the area near the leuco matrix becomes thicker. In the case of display grey state 3 as shown in fig. 4, the liquid pigment is squeezed completely under the leuco matrix.
According to the examples of fig. 2, 3 and 4, the voltage application can change the area of the pigment in the same size area relative to a micro-cup, thereby obtaining better color display effect and higher color saturation.
