Problems solved by technology

[0004] Existing electronic paper display devices of electrophoretic display mode usually require at least two colors of electrophoretic display particles, such as black particles and white particles, in order to realize two-color or color display, but at least two colors of display particles must be It is often difficult to move and maintain stability in an external electric field. In this way, not only the selection of the type and size of the display particles has certain limitations, but also it is difficult to drive and control the movement of the display particles in the external electric field. Therefore, The existing electronic paper display device of electrophoretic display method is not easy to realize two-color or color display

Embodiment 1

[0040] In this embodiment, the colors of the inclined microholes 31 are the same, and electrophoretic display particles of one color are arranged in each inclined microhole 31, and the color of the electrophoretic display particles in each inclined microhole is the same as that in other inclined microwells, Thereby realizing two-color display.

[0041] For example, the inclined microholes 31 are all white, and black electrophoretic display particles 32 are enclosed in each inclined microhole 31 , so as to realize black and white two-color display.

[0042] For example, the inclined microholes 31 are all black, and white electrophoretic display particles 32 are enclosed in each inclined microhole 31 , so as to realize black and white dual-color display.

[0043] For example, the inclined microholes 31 are all single colors such as black, white, blue, green, red, yellow, etc., and the electrophoretic display particles 32 in each inclined microhole 31 can also be black, white, bl...

Embodiment 2

[0047] In this embodiment, the inclined microholes 31 have the same color, and each inclined microhole 31 is provided with electrophoretic display particles of one color to realize color display.

[0048] Specifically, a display principle similar to that of a liquid crystal display can be used, and a display unit is arranged in the inclined microporous layer 3, and the display unit includes at least two successively adjacent inclined microholes 31, and the at least two successively adjacent inclined micropores Electrophoresis in the wells shows that the particles are of different colors.

[0049] For example, if Figure 4 As shown, the inclined microholes 31 are black K, and a display unit 33 is arranged in the inclined microporous layer 3. The display unit 33 includes three successively adjacent inclined microholes 31, and the three successively adjacent inclined microholes 31 The electrophoresis shows that the colors of the particles 32 are different, namely red R, green G,...

Embodiment 3

[0053] In this embodiment, similar to the second embodiment, the color of the inclined microholes 31 is used to achieve colorization.

[0054] Specifically, a display principle similar to that of a liquid crystal display can be used, and a display unit is provided in the inclined microporous layer 31, and the display unit includes at least two successively adjacent inclined microholes, and the at least two successively adjacent inclined microholes The colors are different.

[0055] For example, if Figure 5 As shown, the inclined microporous layer 3 is provided with a display unit 33, and the display unit 33 includes three successively adjacent inclined microholes 31. The colors in the three successively adjacent inclined microholes 31 are different, namely red R , green G, and blue B, and the three inclined microholes 31 include electrophoretic display particles 32 of the same color, such as white or black, or other colors.

[0056] Of course, the colors of the electrophore...

Description

technical field [0001] The invention relates to the field of displays, in particular to an electronic paper display device and a manufacturing method thereof. Background technique [0002] E-paper display technology is a new type of display technology that can achieve a paper-like reading experience. Because the electronic paper display device is comfortable to use, ultra-thin, lightweight, bendable, and ultra-low power consumption, it has been widely concerned and applied in the display field. [0003] In the electronic paper display technology, the electrophoretic display method is mostly used. The electrophoretic display method uses colored electrophoretic display particles, and the electrophoretic display particles are arranged in an orderly manner through the change of the applied electric field, so as to achieve the purpose of color development and present different pictures. [0004] Existing electronic paper display devices of electrophoretic display mode usually r...
