Embodiment 1

[0023] Such as figure 1 As shown, this embodiment provides an electronic ink screen, which is divided into a plurality of pixel areas; the electronic ink screen includes: an array substrate 1 and a color filter substrate 2 arranged opposite to each other, and an array substrate 1 and a color filter substrate 2 located between Ink layer; wherein, the ink layer includes an ink structure 3 corresponding to the pixel area, and the ink structure 3 includes light-shielding ink particles 41 and reflective ink particles 42 .

[0024] Wherein, the light-shielding ink particles 41 may include black ink particles, and the reflective ink particles 42 may include white ink particles. According to different types of electronic ink screens, the specific types of ink particles and the specific types of ink structure 3 are also different. Specifically, for example, when the electronic ink screen is an electronic ink screen based on electrophoretic display technology, the light-shielding ink p...

Embodiment 2

[0036] This embodiment provides a display device, which includes any electronic ink screen provided in Embodiment 1.

[0037] Specifically, the display device in this embodiment may be any product or component with a display function, such as an electronic reader, a navigator, and an electronic photo frame.

[0038] Because the display panel of this embodiment includes the electronic ink screen provided in Embodiment 1, it can realize the color display of the display device based on the electronic ink screen, and the display device is compared with the liquid crystal display device and OLED display in the prior art. devices etc. have the advantage of low power consumption.

Embodiment 3

[0040] This embodiment provides a method for displaying an electronic ink screen, which can be used for any electronic ink screen provided in Embodiment 1. The display method may include the following steps:

[0041] Part of the ink particles in the ink structure 3 of each pixel area moves to the side away from the base of the array substrate 1 under the control of the corresponding driving voltage, so that the electronic ink screen of each pixel area displays a corresponding color; the ink particles include: Light-shielding ink particles 41 , and / or reflective ink particles 42 , and / or colored ink particles 43 .

[0042] Specifically, by controlling the voltage to the pixel electrode and the common electrode of the electronic ink screen, and controlling the electric field between the two electrodes, the movement of various ink particles in the ink structure 3 located in each pixel area can be controlled to form a corresponding display layer. Take the display of a single pix...

Abstract

The invention provides an electronic ink screen, a display device and a display method of the electronic ink screen, belongs to the technical field of display, and can solve the problem that color display of an existing electronic ink screen is difficult to realize. The electronic ink screen is divided into a plurality of pixel regions; the electronic ink screen comprises an array substrate, a color film substrate and an ink layer, wherein the array substrate and the color film substrate are oppositely arranged, and the ink layer is located between the array substrate and the color film substrate, the ink layer comprises an ink structure arranged corresponding to the pixel area, and the ink structure comprises shading ink particles and reflecting ink particles; the color film substrate comprises a color filter layer; the color filter layer comprises color filters which are arranged corresponding to part of the pixel areas; the ink structure at least located in the pixel area where thecolor filter is not arranged further comprises color ink particles, and the color of the color ink particles is different from that of the color filter.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an electronic ink screen, a display device, and a display method for the electronic ink screen. Background technique [0002] With the development of electronic technology, electronic ink screens, as a display screen with low power consumption, are becoming more and more popular among users. [0003] However, in the prior art, the electronic ink screen can only support simple colors and grayscales, such as only black and white, black, white and red, etc., and cannot display very rich colors, resulting in poor user experience. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems in the prior art, and provides an electronic ink screen capable of realizing color display. [0005] The technical solution adopted to solve the technical problem of the present invention is an electronic ink screen, which is divided ...
