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 a special color electronic ink screen, as shown in fig. 1, which is composed of a plurality of pixel blocks 100, each pixel block 100 is provided with a first drive board 1, a second drive board 2, a third drive board 3, a fourth drive board 4, a first microcup 5, a second microcup 6, a third microcup 7, a fourth microcup 8, a first transparent upper electrode plate 9, a second transparent upper electrode plate 10, a first transparent lower electrode plate 11, and a second transparent lower electrode plate 12; the first microcups 5 are located between the first drive plate 1 and the transparent upper electrode plate 9, the second microcups 6 are located between the second drive plate 2 and the second transparent upper electrode plate 10, the third microcups 7 are located between the first transparent lower electrode plate 11 and the third drive plate 3, the fourth microcups 8 are located between the second transparent lower electrode plate 12 and the fourth drive plate 4, and the first microcups 5 and the second microcups 6 respectively correspond to the third microcups 7 and the fourth microcups 8 in position up and down; the driving plate I1 and the driving plate II 2 are positioned above the driving plate III 3 and the driving plate IV 4, the end with larger area of the microcup I5 and the microcup II 6 is the upper end and faces the driving plate I1 and the driving plate II 2, and the end with smaller area is the lower end and faces the transparent upper electrode plate I9 and the transparent upper electrode plate II 10; the end with the larger area of the third microcup 7 and the end with the smaller area of the fourth microcup 8 are the lower ends and face the third drive plate 3 and the fourth drive plate 4, and the end with the smaller area of the third microcup is the upper end and faces the first transparent lower electrode plate 11 and the second transparent lower electrode plate 12;
the driving board I1 is transparent and colorless, and the top surfaces of the driving board I1 and the driving board II 2 are display surfaces; the charged dyeing particles 13, 14, 15 and 16 with the special color one, the special color two, the special color three and the special color four are loaded in the microcups one 5, the microcups two 6, the microcups three 7 and the microcups four 8 respectively, and the electric property of the charged dyeing particles in the same microcups is the same.
It should be noted that, the microcups are the existing structure, and the area of one end of the microcups is usually much larger than that of the other end (the ratio is larger than 10/1), and this embodiment utilizes the structural characteristics of the microcups to eliminate the color shielding effect between the upper and lower microcups.
Further, the charged dyed particles in the upper and lower corresponding microcups one 5 and three microcups three 7 are opposite in electrical property, and the charged dyed particles in the upper and lower corresponding microcups two 6 and four microcups four 8 are opposite in electrical property. For example, the charged dyed particles in microcup one and microcup two are both positively charged, and the charged dyed particles in microcup three and microcup four are both negatively charged.
In this embodiment, insulating plates are disposed between the first transparent upper electrode plate 9 and the second transparent upper electrode plate 10, between the first transparent lower electrode plate 11 and the second transparent lower electrode plate 12, between the first transparent upper electrode plate 9 and the first transparent lower electrode plate 11, and between the second transparent upper electrode plate 10 and the second transparent lower electrode plate 12. The setting of insulation board can avoid the electric field that each microcup corresponds to influence each other to can control the electrified dyed particle in the microcup one and the microcup two on upper strata, the microcup three and the microcup four on lower floor respectively and remove.
It should be noted that, when the charged dyed particles in the first microcup move to cover the top of the first microcup, the charged dyed particles in the second microcup are located at the bottom of the first microcup, and the charged dyed particles in the third microcup and the fourth microcup are located at the top of the first microcup, the user can see the special color one but cannot see the special color two, the special color three and the special color four (because the area of the lower end of the second microcup close to the transparent upper electrode plate two is far smaller than the area of the upper end of the first driving plate, and the area of the upper ends of the third microcup and the fourth microcup close to the transparent lower electrode plate one and the transparent lower electrode plate two is far smaller than the area of the lower end of the second driving plate, the user can hardly see the colors of the charged dyed particles at the lower end of the second microcup and the upper ends of the third microcup and the fourth microcups). Similarly, when the charged dye particles in microcup two move to cover the top, the charged dye particles in microcup one are at the bottom, and the charged dye particles in microcup three and microcup four are at the top, the user can see the special color two but not the special color one, the special color three and the special color four.
When the charged dyeing particles in the third microcup move to cover the bottom of the third microcup, the charged dyeing particles in the first microcup and the second microcup are positioned at the bottom of the third microcup, and the charged dyeing particles in the fourth microcup are positioned at the top of the fourth microcup, a user can see the special color three but can hardly see the special color one, the special color two and the special color four (because the area of the lower end of the first microcup and the second microcup, which are close to the transparent upper electrode plate one and the second microcup, is far smaller than the area of the upper end of the first drive plate one, the shielding influence of the bottoms of the first microcup and the second microcup on the third microcup and the fourth microcup is almost negligible, and the area of the upper end of the third microcup and the fourth microcup, which is close to the transparent lower electrode plate one and the second, the color of the charged dyeing particles at the top of the fourth microcup can hardly be seen by the user, so the user can only see the special color three). Similarly, when the charged dyed particles in microcup four move and cover the bottom, the charged dyed particles in microcup one and microcup two are located at the bottom, and the charged dyed particles in microcup three are located at the top, the user can see the special color four and hardly see the special colors one, two and three.
In the above process, since the charged dye particles to be involved in color development are driven to the top or the bottom of the microcups, the design of the driving circuit is very simple, and the gray color generation process is not provided in the middle, so the refresh efficiency is very high.
It should be noted that the color of the driving board two may further be a basic color, such as white, which is commonly used in a smart classroom.
Furthermore, the first microcup, the second microcup, the third microcup and the fourth microcup are respectively driven by separate driving circuits.
Example 2
The embodiment provides a method for using the special color electronic ink screen described in embodiment 1, which specifically includes the following steps:
corresponding voltages are applied to the first driving plate, the first transparent upper electrode plate, the second driving plate, the second transparent upper electrode plate, the third driving plate, the first transparent lower electrode plate, the fourth driving plate and the second transparent lower electrode plate, so that corresponding electric fields are formed between the first driving plate and the first transparent upper electrode plate, between the second driving plate and the second transparent upper electrode plate, between the third driving plate and the first transparent lower electrode plate and between the fourth driving plate and the second transparent lower electrode plate, charged dyeing particles needing to participate in color development move to the top or the bottom of the microcup, and the rest of the charged dyeing particles are located at the bottom or the top of the microcup.
Taking the example that the special color one is black, the special color two is red, the special color three is blue, and the special color four is green, and the base color on the driving board two is white:
if black is to be displayed, black can be made by a combination of black blue or black green, or light black can be made by black and white colors. The charged dyed particles in the first microcup are adjusted to move to the top of the first microcup to show black, and the charged dyed particles in the second microcup move to the bottom of the second microcup. And adjusting the charged dyed particles of one of the microcup three or microcup four to move and cover at the bottom and the other to move and cover at the top, or the charged dyed particles of both microcup three and microcup four to move and cover at the top.
If white is to be displayed, the charged dyeing particles in the first microcup and the second microcup are adjusted to move and cover the bottom, and the charged dyeing particles in the third microcup and the fourth microcup move and cover the top.
If the display of red color is required, the charged dye particles in the first microcup are driven to move to the bottom, the charged dye particles in the second microcup are driven to move to the top, and the charged dye particles in the third microcup and the fourth microcup are driven to move to the top. The green and blue displays are similar.
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.
