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.
The present embodiment provides an electronic ink panel for generating a dedicated color based on mixed color, as shown in fig. 1-2, comprising a plurality of pixel blocks 1 (only one pixel block is shown in the figure), wherein the pixel blocks 1 contain a plurality of microcapsules or microcups 2, each microcapsule or microcup 2 contains charged dyed particles 3 having a primary color and charged dyed particles 4 having a mixed color primary color, the charged dyed particles 3 having the primary color in one microcapsule or microcup 2 have the same electrical property, the charged dyed particles 4 having the mixed color primary color have the same electrical property, and the charged dyed particles 3 having the primary color and the charged dyed particles 4 having the mixed color primary color have different electrical properties; the colors of the charged dyeing particles 3 with the primary color in all the microcapsules or the microcups 2 are the same, and the colors of the charged dyeing particles 4 with the mixed color primary color between each microcapsule or microcup 2 in the same pixel block 1 are different; at the same time, at least one microcapsule or microcup charged dyeing particle 3 with base color or at least two microcapsules or microcups charged dyeing particle 4 with mixed color base color in one pixel block are covered on the top of the microcapsule or microcup for color development. That is, monochrome color development or color mixture development of a base color is performed.
Preferably, each pixel block 1 contains 3-4 microcapsules or microcups 2. The arrangement of the microcapsules or microcups 2 in each pixel block 1 is not limited, and when three microcapsules or microcups 2 are accommodated in one pixel block 1, the microcapsules or microcups 2 are arranged in a shape of Chinese character pin, as shown in fig. 1, and when four microcapsules or microcups are accommodated, the microcapsules or microcups 2 are arranged in a shape of Chinese character 'tian', as shown in fig. 2, which is a preferred choice. It should be noted that, in fig. 1, the area of the top of the triangle-shaped microcapsule or microcup is consistent with the sum of the areas of the tops of the other two microcapsules or microcups, and just fills the whole pixel region.
The working principle of the electronic ink screen is as follows: when the number of microcapsules or microcups in a pixel block is three, the mixed color basic color in each microcapsule or microcup is expressed as color one, color two, and color three (for example, color one is yellow, color two is magenta, color three is blue, and the basic color is white). This can form 3 kinds of double color mixing: the color development ratio of the first color and the second color mixture, the first color and the third color mixture, and the second color and the third color mixture is 2/3 color development (two microcapsules or charged dye particles in the microcups are displayed simultaneously, so 2/3). In addition, the color mixture of three colors is 1, which is formed by mixing the first color, the second color and the third color together, and the color development ratio is 100 percent.
And according to the target special color to be displayed, driving voltage is supplied to the corresponding microcapsule or microcup for driving, so that an electric field is formed in the microcapsule or microcup, charged dyeing particles in each microcapsule or microcup in the pixel block correspondingly move, the charged dyeing particles needing to participate in color development move and cover the top of the microcapsule or microcup, and the charged dyeing particles not participating in color development are positioned at the bottom of the microcapsule or microcup.
It should be noted that the color ratio result is calculated when the sizes of the three microcapsules or microcups are consistent, and in practical cases, the sizes of the microcapsules or microcups can be determined as needed, so that the color ratio can be adjusted appropriately as needed (the sizes of the microcapsules or microcups are not consistent as shown in fig. 1).
The color having a large color difference and a high color rendering ratio may be selected and mixed to generate a dedicated color, and if the color rendering ratio is low, the graininess presented by the ink screen becomes stronger. If the base color is white, 100% of the color can be developed. The mixture of yellow, magenta, and blue results in a black color that is 100% developed, magenta and yellow may constitute 2/3 developed magenta, yellow and blue may constitute 2/3 developed green, and blue and magenta may constitute 2/3 developed cyan. If the application scene is an intelligent classroom, at the moment, only five special colors of black, white, blue, green and red need to be displayed, and the intelligent classroom is completely sufficient.
Further, in the present embodiment, the three microcapsules or microcups in each pixel block are driven by three different driving circuits, respectively. For example, the first microcapsule or microcup may be driven individually to move and cover the yellow or white charged dye particles on the top of the first microcapsule or microcup, the second microcapsule or microcup may be driven individually to move and cover the magenta or white charged dye particles on the top of the second microcapsule or microcup, and the third microcapsule or microcup may be driven individually to move and cover the blue or white charged dye particles on the top of the third microcapsule or microcup. Thus, independent control of the microcapsule or the microcup I, the microcapsule or the microcup II and the microcapsule or the microcup III can be realized, so that the pixel can be controlled to be colored into black of red, yellow and blue combination, white of white and white combination, dark blue of blue, red and white combination, green of blue, yellow and white, and dark red of yellow, red and white combination. The driving is not much different from the black and white driving, only the basal color in one microcapsule or microcup needs to be placed on top, and the non-basal color is automatically placed on the bottom, or vice versa, so that the refreshing efficiency is very high.
It should be noted that, when the number of microcapsules or microcups in one pixel block is four, the mixed color basic color in one pixel block is respectively recorded as color one, color two, color three, and color four. For example, the first color is yellow, the second color is magenta, the third color is blue, the fourth color is black, and the background color is white. This can achieve 6 kinds of double color mixing: the first color and the second color, the first color and the third color, the first color and the fourth color, the second color and the third color, the second color and the fourth color, and the third color and the fourth color. The color development ratio of each double color mixture at this time was 1/2. There are 4 kinds of three mixed colors, which are color one, two and three mixed colors, color one, two and four mixed colors, color one, three and four mixed colors, and color two, three and four mixed colors, and the color ratio of each three mixed color is 3/4 color. One of four-color mixture, one, two, three and four-color mixture, the color ratio is 100%.
It should be noted that the color ratio result is calculated when the sizes of the four microcapsules or microcups are consistent, and in actual situations, the sizes of the microcapsules or microcups can be adjusted as needed, so that the color ratio can be properly adjusted as needed.
The color mixture having a large color difference and a high color rendering ratio may be selected to generate a dedicated color, and if the color rendering ratio is low, the graininess presented by the ink screen becomes stronger.
Further, the four microcapsules or microcups of each pixel are individually driven by four different driving circuits. The microcapsules or microcups may be actuated individually to have yellow color on top or white color on top, or the microcapsules or microcups may be actuated individually to have magenta color on top or white color on top, or the microcapsules or microcups may be actuated individually to have blue color on top or white color on top, or the microcapsules or microcups may be actuated individually to have black color on top or white color on top. Realizing the independent control of the microcapsule or microcup I, the microcapsule or microcup II, the microcapsule or microcup III and the microcapsule or microcup IV.
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 of the pixel block.
For example, the skilled person in the art should understand that the number of the microcapsules or the microcups is increased to one pixel block to accommodate 5 microcapsules or microcups or 6 microcapsules or microcups, which is consistent with the ink screen and the color development scheme provided in the embodiment.
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.
