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 a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides an electronic ink screen based on four special colors, which comprises a plurality of pixel blocks 1 (only one pixel block structure is shown in the figure), wherein each pixel block 1 consists of three or four microcapsules or microcups 2 (three microcapsules or microcups are shown in figure 1, and four microcapsules or microcups are shown in figure 2); each microcapsule or microcup 2 is arranged in a straight line (such as the horizontal arrangement of III and IIII or the vertical arrangement after rotating 90 degrees); each microcapsule or microcup 2 is loaded with two charged dyeing particles with different colors, the charged dyeing particles with different colors have different electrical properties, and the charged dyeing particles with the same color have the same electrical property; wherein each microcapsule or microcup 2 is loaded with charged dyeing particles 3 with a special color one; when the number of the microcapsules or the microcups 2 is three, the three microcapsules or the microcups 2 are also respectively loaded with charged dyeing particles 4 with a special color two, a special color three and a special color four; when the number of the microcapsules or the microcups 2 is four, three microcapsules or microcups 2 are respectively loaded with the charged dyeing particles 4 with the special color two, the special color three and the special color four, and the rest microcapsule or microcup is loaded with the charged dyeing particles 4 with one of the special color two, the special color three and the special color four.
In this embodiment, in each microcapsule or microcup, the charged dyed particles 3 with a specific color one are positively charged and the charged dyed particles 4 with another specific color (specific color two, specific color three or specific color four) are negatively charged.
Note that the primary color is the primary color, and since the charged dye particles with the primary color are loaded in each microcapsule or microcup, the color development ratio is the highest. When there are four microcapsules or microcups, the rest microcapsule or microcup is loaded with the capsule with the special color, which can be determined according to the actual requirement, because when there are two microcapsules or microcups with the special color, the special color is the color with the highest color rendering ratio except the special color one. For example, in the case of using black and white in many cases, the specific color, i.e., white, may be set, and two microcapsules or microcups may be provided, each of which contains charged black dye particles, thereby increasing the color development ratio of black.
For example, the dedicated color one may be white, i.e., the base color, the dedicated color two may be black, the dedicated color three may be red, and the dedicated color four may be green. Of course, different primary colors and special colors can be selected according to different types or use occasions of the ink screen, for example, the primary color of the common ink screen is white, the primary color of the eye-protection screen is green, and the like. The base color can be a background color commonly used for the electronic ink screen, and can also be a color with the largest display proportion as required.
It should be noted that the specific structure of the microcapsule or microcup can be referred to the related description in chinese patent application CN 103091926A.
The color rendering ratio is a ratio of a color rendering area in a pixel block in the case of rendering a specific color. For example, for the specific color one, when the color is developed, all four microcapsules or microcups can display the specific color one, so that the maximum color developing ratio of the specific color one is 100%. When only three microcapsules or microcups are present, only one microcapsule or microcup can display the corresponding dedicated color when the dedicated color two, the dedicated color three and the dedicated color four are developed, so that the developing ratio is 1/3. When there are four microcapsules or microcups, one dedicated color exists in two microcapsules or microcups, the maximum color rendering ratio of the dedicated color is 50%, and the color rendering ratios of the other two dedicated colors are 25%.
It should be noted that the order of the microcapsules or microcups may not be limited. Preferably, when there are four microcapsules or microcups, two capsules of the same color of the charged dyed particles are spaced apart. For example, when two microcapsules or microcups are loaded with charged dyed particles having a specific color one and a specific color two, the two microcapsules or microcups are separated by at least one other microcapsule or microcup. Therefore, the electronic ink screen has a more uniform color rendering effect.
Still further, the ordering of individual microcapsules or microcups may also be considered in terms of parameters of other dedicated colors besides the base color, including but not limited to color depth, color value, reflection wavelength, and the like. For example, in the color depth, black > blackish green > red are arranged in this order.
In the present embodiment, each microcapsule or microcup 2 is individually driven using a different driving circuit. Therefore, the movement of the charged dyeing particles in each microcapsule or microcup can be independently controlled and driven, and more diversified color development requirements can be met.
More specifically, a driving voltage may be applied to each of the capsules to form an electric field therein, so that the charged dyed particles that are required to participate in the color development move to cover the top of the microcapsule or the microcup, and the charged dyed particles that are not required to participate in the color development are located at the bottom of the microcapsule or the microcup. Taking the example that the special color I is white, namely the primary color, the special color II is black, the special color III is red, the special color IV is green, and four microcapsules or microcups are taken as examples, the color development can be controlled to be red, white and white combined white of red, white, black combined black, green, white and green combined green. The difference between the drive circuit and black-white drive is small, the refresh efficiency is high, and the color development is bright.
As another embodiment, when there are four microcapsules or microcups, two loaded microcapsules or microcups with the same charged dye particles are driven with the same driving circuit (since the color development of the two microcapsules or microcups is uniform).
Example 2
The embodiment provides a color development method using the electronic ink screen described in embodiment 1, which includes the following specific steps:
the charged dye particles with the special color one in each microcapsule or microcup are charged with positive or negative charges, and the charged dye particles with other colors are charged with opposite charges.
And acquiring the color required to be displayed by each pixel block according to the color development requirement of the display interface.
And according to the color to be displayed, corresponding driving voltage is applied to the corresponding pixel block for driving, so that an electric field is formed in the pixel block, charged dyeing particles needing to participate in color development in each microcapsule or microcup move to the top of the microcapsule or microcup, and other charged dyeing particles not needing to participate in color development are positioned at the bottom of the microcapsule or microcup.
In the electronic ink screen, although the dedicated colors other than the first dedicated color are only partially colored in each pixel block, and the other colors are background colors, the electronic ink screen still has good color rendering capability, and although a slight graininess may exist, the electronic ink screen has little influence on the use experience.
It should be noted that fig. 1-2 are schematic plan views of the top surface of the pixel block, and the front surface is the top surface.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
