Description
Technical Field
The invention relates to the field of electronic ink screens, in particular to a color electronic ink screen and a display method thereof.
Background
The electronic ink screen is rapidly developed based on the characteristics of power saving and eye protection, but the electronic ink screen is generally in black and white, so that the development of the electronic ink screen to multimedia is restricted.
The electronic ink is realized by controlling charged white and black micro-particles in the microcapsule, as shown in fig. 1, the particles have positive and negative charges, and controlling the white and black particles up and down by controlling circuits on the front and bottom of the microcapsule. As shown in fig. 2, three colors of black, white and gray are obtained.
In order to realize color display by the electronic ink screen, there are two embodiments:
(1) as shown in fig. 3, the color electronic ink screen 10 manufactured by using the color filter has a disadvantage that a backlight is required for reflection, and thus effective eye protection cannot be achieved. The use of color filters, because of the color, requires increased backlight brightness, which does not achieve the purpose of eye protection.
(2) As shown in fig. 4, different colors are seen by moving the particles of different colors to the upper layer using the same applied voltage, wherein 20 are yellow particles, 30 are cyan particles, 40 are magenta particles, and 50 are white particles. Because the position conversion of the particles with different colors is carried out in the same cavity through different voltages, the conversion time of each pixel point is increased, for example, the color conversion can be obtained by one time of double-color black and white, and the color conversion can be obtained by N-1 times of conversion of colors.
Disclosure of Invention
In view of the above disadvantages, an object of the present invention is to provide a color electronic ink screen and a display method thereof, which can achieve a color display purpose and also have an eye protection effect, and the position conversion time of different color particles in microcapsules in each pixel point is not increased.
The technical scheme adopted by the invention to achieve the aim is as follows:
a color electronic ink screen is provided with a plurality of pixel points, and is characterized in that each pixel point is composed of a plurality of microcapsules, and each microcapsule is internally provided with a plurality of types of light primary color particles.
As a further improvement of the invention, each pixel point is composed of at least three microcapsules.
As a further improvement of the invention, each pixel point is composed of three or four microcapsules.
As a further development of the invention, each of the microcapsules has at least two light primary particles inside.
The display method based on the color electronic ink screen is characterized by comprising the following steps of:
(1) carrying positive and negative charges on different light-based color particles in the microcapsule;
(2) positive and negative charges are applied to the positive and negative electrodes of the microcapsule, so that different primary light color particles in the microcapsule move up and down to change the display color of the microcapsule;
(3) different ratio rows of microcapsules with different colors in each pixel are obtained through voltage control, and certain gray scale control is formed corresponding to gray scale values, so that a light mixing effect is formed.
As a further improvement of the invention, in the step (3), the voltages of +1 to +12V and-1 to-12V are divided into 16-step voltage control according to 16-step gray scale to obtain different ratio rows of microcapsules with different colors in each pixel, and then the comparison is performed with the 16-step gray scale to obtain corresponding gray scale values, i.e. a certain gray scale control is formed, thereby forming the light mixing effect.
The invention has the beneficial effects that: through the special design of the pixel points in the color electronic ink screen and the special display method, the aim of color display is fulfilled, the eye protection effect is achieved, and the position conversion time of different color particles in the microcapsules in each pixel point is not increased.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purposes, the following detailed description of the embodiments of the present invention is provided with the accompanying drawings and the preferred embodiments.
The embodiment of the invention provides a color electronic ink screen which is provided with a plurality of pixel points, wherein each pixel point is composed of a plurality of microcapsules, and each microcapsule is internally provided with a plurality of types of light primary color particles.
In this embodiment, each of the microcapsules has at least two types of primary light particles therein. The primary light-emitting particles may be different colors, for example, the primary light-emitting particles in each microcapsule are at least two of red, green, blue and white. For example, as shown in fig. 5, the microcapsule contains red particles a and green particles B; as shown in fig. 6, the microcapsule has green particles B and blue particles C inside; as shown in fig. 7, the microcapsule contains red particles a and blue particles C; as shown in fig. 8, the microcapsule contains red particles a, white particles D, and green particles B; as shown in fig. 9, the microcapsule contains green particles B, white particles D, and blue particles C. In addition to these combinations, there are other combinations.
In this embodiment, each pixel point is composed of at least three microcapsules. Specifically, each pixel point is composed of three or four microcapsules, as shown in fig. 10 to 12. Specifically, as shown in fig. 10, the pixel point is composed of 1 red microcapsule E, 1 green microcapsule F and 1 blue microcapsule G; as shown in fig. 11, the pixel point is composed of 1 red microcapsule E, 2 green microcapsules F and 1 blue microcapsule G; as shown in fig. 12, the pixel point is composed of 1 red microcapsule E, 1 green microcapsule F, 1 blue microcapsule G, and 1 white microcapsule H.
Of course, the different colored microcapsules in each of the pixels may be present in a variety of different proportions, for example, red microcapsules: green microcapsule: blue microcapsule 1: 2: 1, or, red microcapsule: green microcapsule: white microcapsule: blue microcapsule is 1: 2: 1.
the invention also provides a display method based on the color electronic ink screen, which comprises the following steps:
(1) carrying positive and negative charges on different light-based color particles in the microcapsule;
(2) positive and negative charges are applied to the positive and negative electrodes of the microcapsule, so that different primary light color particles in the microcapsule move up and down to change the display color of the microcapsule;
(3) different ratio rows of microcapsules with different colors in each pixel are obtained through voltage control, and certain gray scale control is formed corresponding to gray scale values, so that a light mixing effect is formed.
Specifically, in the step (3), the +1 to +12V voltage and the-1 to-12V voltage are divided into 16-order voltage control according to the 16-order gray scale to obtain different ratio rows of microcapsules with different colors in each pixel, and then the comparison is performed with the 16-order gray scale to obtain corresponding gray scale values, i.e., a certain gray scale control is formed, so as to form the light mixing effect.
The following examples illustrate: the red particles A are positively charged, the green particles B are negatively charged, positive and negative charges are charged on the positive and negative electrodes of the microcapsule, and the red particles A and the green particles B are moved up and down according to the principle that the positive and negative charges attract each other and the like charges repel each other. By controlling the voltage, for example, dividing the voltages (+1 to +12V) and (-1 to-12V) into 16-step voltage controls according to 16-step gray scale, as shown in table 1 below, different ratio rows of the red microcapsule and the green microcapsule in each pixel can be obtained, as shown in fig. 13, the red microcapsule and the green microcapsule respectively account for 50%, that is, corresponding to gray scale 8 or 9, a certain gray scale control can be formed, so that a light mixing effect, that is, a color display effect can be achieved.
