fig. 2 is a schematic structural diagram of an electronic ink screen in embodiment 2 of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
Example 1
The embodiment provides an electronic ink screen for realizing three special colors, as shown in fig. 1, which includes a first driving board 1, a second driving board 2, a first micro-cup 3, a second micro-cup 4, and a transparent polar plate;
the charged dyeing particles 5 with the first special color are loaded in the microcup I3, and the electric property of all the charged dyeing particles 5 in the microcup I3 is the same; the charged dyeing particles 6 with the second special color are loaded in the microcup two 4, the driving plate two 2 has the third special color, and the electric properties of all the charged dyeing particles 6 in the microcup two 4 are the same;
the transparent electrode plate is formed by overlapping an upper transparent electrode plate 7 and a lower transparent electrode plate 8, the first microcup is positioned between the first drive plate and the upper transparent electrode plate, the second microcup is positioned between the second drive plate and the lower transparent electrode plate, and the positions of the first microcup and the second microcup are in one-to-one correspondence; the outward side of the first driving board is a display surface;
the area of one side of the first microcup close to the first drive plate is larger than the area of one side of the first transparent electrode plate, and the area of one side of the second microcup close to the second drive plate is larger than the area of one side of the lower transparent electrode plate (so that when charged dyeing particles in the second microcup are used for displaying colors, shielding of one side of the first microcup close to the upper transparent electrode plate can be omitted, and a user can directly see the color displayed by the charged dyeing particles in the second microcup close to the second drive plate). It should be noted that, the microcups are the existing structure, and the area of one side is usually much larger than that of the other side (the ratio is larger than 10/1), and this embodiment utilizes the structural features of the microcups to eliminate the color blocking effect between the two microcups.
The electric fields between the upper transparent electrode plate and the drive plate I, and between the lower transparent electrode plate and the drive plate II are respectively controlled, and the movement of charged dyeing particles in the microcups I and the microcups II is respectively controlled.
In this embodiment, a transparent insulating plate is disposed between the upper transparent electrode plate and the lower transparent electrode plate. The transparent insulating plate can effectively prevent particles between the two corresponding microcups I and the microcups II from generating interference.
In this embodiment, the first microcups and the second microcups are vertically symmetrical along the transparent plate.
In this embodiment, the second driving board has a third dedicated color which is the lightest dedicated color of the three dedicated colors. Therefore, the interference of the special color of the second driving plate on the special color displayed in the first microcup and the second microcup can be avoided as much as possible (namely the upper layer and the lower layer can draw colors, and when the color of the lower layer is lighter, the influence on the color of the upper layer is relatively smaller).
The driving plate I and the upper transparent electrode plate can be provided with a plurality of microcups I, and the driving plate II and the lower transparent plate can be provided with a plurality of microcups II.
In addition, the upper transparent polar plate and the lower transparent polar plate can adopt an integrated or split structure, and when the split structure is adopted, the upper transparent polar plates of the split bodies are electrically connected.
Further, the first driving board is transparent.
In the present embodiment, the dedicated colors are all conventional colors, and the term "dedicated color" refers to a specific color used in a specific scene.
Example 2
This example is substantially the same as example 1, and is mainly different from example 1 in that, as shown in fig. 2, charged dyed particles 6 and 9 having a second specific color and a third specific color are simultaneously loaded in the microcups two 4, and the color of the driving plate two is transparent; the charged dyed particles with different colors in the microcups II have different electrical properties, and the charged dyed particles with the same color have the same electrical property.
Example 3
The embodiment provides a method for utilizing the electronic ink screen described in embodiment 1, which specifically comprises the following steps:
when the first special color needs to be displayed, a driving voltage is applied to the first driving plate and the upper transparent electrode plate to form a first electric field between the first driving plate and the upper transparent electrode plate, and charged dyed particles with the first special color in the first microcups move to one sides of the first microcups, which are close to the first driving plate, so that the first special color is displayed; at the moment, the second driving plate and the lower transparent electrode plate do not apply driving voltage; the first special color can shield the second special color of the charged dyeing particles in the second microcup, and can shield the third special color of the second driving plate.
When the second special color needs to be displayed, a driving voltage is applied to the upper transparent electrode plate and the second driving plate to form a second electric field between the upper transparent electrode plate and the second driving plate, so that the charged dyeing particles in the first microcup are gathered to one side of the first microcup, which is close to the upper transparent electrode plate, and meanwhile, a driving voltage is applied to the lower transparent electrode plate and the second driving plate to form a third electric field between the first microcup and the second driving plate, so that the charged dyeing particles in the second microcup are gathered to one side of the second microcup, which is close to the second driving plate, and at the moment, the second special color displayed by the second microcup can cover the third special color of the second driving plate, and a user can only see the second special color.
It should be noted that, because the area of the side of the first microcup close to the first driving plate is much larger than the area of the side of the first microcup close to the upper transparent electrode plate, and the area of the side of the second microcup close to the second driving plate is much larger than the area of the side of the second microcup close to the lower transparent electrode plate, it can be understood that the first special color with a small area covers the side of the second microcup with a larger area close to the second driving plate, and therefore the shielding of the first special color can be ignored.
When the third special color needs to be displayed, a driving voltage is applied to the first driving plate and the upper transparent electrode plate to enable a second electric field to be formed between the first driving plate and the upper transparent electrode plate, so that the charged dyeing particles in the first microcup are gathered to one side of the first microcup, which is close to the upper transparent electrode plate, and meanwhile, a driving voltage is applied to the lower transparent electrode plate and the second driving plate to enable a fourth electric field to be formed between the lower transparent electrode plate and the second driving plate, so that the charged dyeing particles in the second microcup are gathered to one side of the second microcup, which is close to the lower transparent electrode plate. Because the areas of the first microcup close to the upper transparent electrode plate and the second microcup close to the lower transparent electrode plate are very small, a user can hardly see the first special color and the second special color, but can only see the third special color on the second driving plate.
Example 4
The embodiment provides a method for utilizing the electronic ink screen of embodiment 2, which specifically comprises the following steps:
when the first special color needs to be displayed, a driving voltage is applied to the first driving plate and the upper transparent electrode plate to form a first electric field between the first driving plate and the upper transparent electrode plate, so that the charged dyed particles in the first microcup move to cover one side close to the first driving plate, the driving voltage is not applied to the second driving plate and the lower transparent electrode plate, and the first special color can shield the color of the charged dyed particles in the second microcup.
When the second special color needs to be displayed, a driving voltage is applied to the first driving plate and the upper transparent electrode plate to form a second electric field between the first driving plate and the upper transparent electrode plate, so that the charged dyeing particles in the first microcup are gathered to one side of the first microcup, which is close to the upper transparent electrode plate, while a driving voltage is applied to the second driving plate and the lower transparent electrode plate to form a third electric field between the second driving plate and the lower transparent electrode plate, so that the charged dyeing particles with the third special color in the second microcup are gathered to one side of the second microcup, which is close to the lower transparent electrode plate, and the charged dyeing particles with the second special color are gathered to one side of the second microcup, which is close to the second driving plate.
It should be noted that, because the area of the side of the first microcup close to the first driving plate is much larger than the area of the side of the first microcup close to the upper transparent electrode plate, and the area of the side of the second microcup close to the second driving plate is much larger than the area of the side of the second microcup close to the lower transparent electrode plate, the area where the charged dyed particles with the first special color and the charged dyed particles with the third special color are gathered is very small, and a user can hardly see the second special color of the charged dyed particles of the second microcup close to the second driving plate.
When a third special color needs to be displayed, a driving voltage is applied to the first driving plate and the upper transparent electrode plate to form a second electric field between the first driving plate and the upper transparent electrode plate, so that the charged dyeing particles in the first microcup are gathered to one side of the first microcup, which is close to the upper transparent electrode plate, while a driving voltage is applied to the second driving plate and the lower transparent electrode plate to form a fourth electric field between the second driving plate and the lower transparent electrode plate, so that the charged dyeing particles with the second special color are gathered to one side of the second microcup, which is close to the lower transparent electrode plate, and the charged dyeing particles with the third special color are gathered to one side of the second microcup, which is close to the second driving plate.
It should be noted that, because the area of the side of the first microcup close to the first driving plate is much larger than the area of the side of the first microcup close to the upper transparent electrode plate, and the area of the side of the second microcup close to the second driving plate is much larger than the area of the side of the second microcup close to the lower transparent electrode plate, the area where the charged dyed particles with the first special color and the charged dyed particles with the second special color are gathered is very small, and a user can hardly see the third special color of the charged dyed particles of the second driving plate close to the second microcup.
It should be noted that, in the electronic ink screens of embodiments 1 and 2, the first microcup has only one kind of electrically charged particles, and the second microcup has only one kind of electrically charged particles or two kinds of electrically different particles, which is helpful for simplifying the driving circuit, does not need a complicated algorithm design, does not need to perform local refreshing after global refreshing every time, and improves the refreshing efficiency.
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.
