when the special color I or the special color II needs to be displayed, corresponding driving voltage is applied to the first driving plate and the second driving plate, an electric field is formed between the first driving plate and the second driving plate, so that dyed particles in the microcup structure, the colors of which can be changed between the special color I and the special color II, move and cover the upper end of the microcup structure, the other dyed particles move at the lower end of the microcup, and the dyed particles at the upper end of the microcup structure are excited by the first color-changing excitation circuit to display the required special color I or the special color II (at this time, the area of the lower end of the microcup structure is extremely small, so that a user cannot see the color of the dyed particles at the lower end of the microcup structure);
when the special color three or the special color four needs to be displayed, corresponding driving voltage is applied to the first driving plate and the second driving plate, an electric field is formed between the first driving plate and the second driving plate, so that the dyed particles in the microcup structure, the colors of which can be changed between the special color three and the special color four, move to cover the upper end of the microcup structure, the other dyed particles move to the lower end of the microcup, and the dyed particles at the upper end of the microcup structure are excited by the second color-changing excitation circuit to display the required special color three or the special color four.

when the color of the second driving board needs to be displayed, corresponding driving voltage is applied to the first driving board and the second driving board, so that an electric field is formed between the first driving board and the second driving board, and therefore, dyed particles, of which the colors can be changed between the special color I and the transparent color, in the microcup structure move and cover the upper end of the microcup structure, and the other dyed particles move at the lower end of the microcup and excite the dyed particles at the upper end of the microcup structure to display the transparent color by using the first color-changing excitation circuit, and at the moment, the color of the second driving board can be seen by a user (at the moment, the color of the upper end of the microcup structure which can be seen by the user is the transparent color, the area of the lower end of the microcup structure is small, the shielding of the transparent plate of the second driving board can be ignored, and the color of the second driving board can be seen by the user actually.
Similarly, for example, when the color-changing material is a photochromic material, the light source control circuit can be used to emit light sources such as infrared rays or ultraviolet rays to excite the coloring particles to change color; for another example, when the color-changing material is a thermosensitive color-changing material, the temperature control circuit can be used for changing the ambient temperature to excite the dyeing particles to change color; for another example, when the color-changing material is a magnetic color-changing material, the magnetic field control circuit can be used to change the magnetic field and excite the coloring particles to change color.
Example 6
The embodiment provides a color rendering method of an ink screen in embodiment 3, which includes the following specific steps:
when the special color I needs to be displayed, corresponding driving voltage is applied to the first driving plate and the second driving plate, an electric field is formed between the first driving plate and the second driving plate, so that dyed particles in the microcup structure, the colors of which can be changed between the special color I and the transparent color, move and cover the upper end of the microcup structure, the other dyed particles move at the lower end of the microcup, and the dyed particles at the upper end of the microcup structure are excited by the first color-changing excitation circuit to display the required special color I;
when the special color two or the special color three needs to be displayed, corresponding driving voltage is applied to the driving plate I and the driving plate II, an electric field is formed between the driving plate I and the driving plate II, so that dyed particles in the microcup structure, the colors of which can be changed between the special color two and the special color three, move to cover the upper end of the microcup structure, the other dyed particles move to the lower end of the microcup, and the dyed particles at the upper end of the microcup structure are excited by the color change excitation circuit II to display the required special color two or the special color three;
when the color of the driving board II needs to be displayed, corresponding driving voltage is applied to the driving board I and the driving board II, so that an electric field is formed between the driving board I and the driving board II, so that the dyed particles with the colors capable of being changed between the special color I and the transparent color in the microcup structure move and cover the upper end of the microcup structure, the other dyed particles move at the lower end of the microcup, and the dyeing particles at the upper end of the microcup structure are excited by the first color-changing excitation circuit to display transparent color, the second drive board is excited by the third color-changing excitation circuit to display required special color four or special color five, and at the moment, the user can see the color of the second drive board (at the moment, the color at the upper end of the microcup structure which can be seen by the user is transparent color, the area at the lower end of the microcup structure is very small, the shielding of the transparent board on the second microcup structure can be ignored, and therefore, the user can actually see the color of the second drive board).
Similarly, for example, the color-changing material is a photochromic material, and the color-changing material can be excited by a light source such as infrared ray or ultraviolet ray emitted by a light source control circuit to change the color of the dyed particles; if the color-changing material is a thermosensitive color-changing material, the temperature control circuit can be used for changing the ambient temperature to excite the dyeing particles to change color; if the color-changing material is a magnetic color-changing material, the magnetic field control circuit can be used for changing the magnetic field and exciting the coloring particles to change color.
In the above embodiments, since there are only two types of the dyeing particles in the microcup structure, the driving method is very simple, and only two types of the dyeing particles need to be driven to the upper end of the microcup or the dyeing particles need to be driven to the lower end of the microcup, so that the refresh efficiency is higher.
It should be noted that the ink panel described in example 1-2 is a four-color ink panel, and the ink panel described in example 3 is a five-color ink panel.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
