Problems solved by technology

At present, although some progress has been made in the flexible display screen based on electrophoresis, there are still a series of problems that need to be solved, such as slow response speed (hundreds of milliseconds), difficulty in realizing color (using different filters to achieve color), and high production cost.

Embodiment 1

[0023] Such as figure 1 As shown, the bottom layer of the printed flexible display screen provided in this embodiment is the printing layer, and the printing ink layer is attached to the printing layer, and the light-transmitting layer, the electrode layer A, and the electronically controlled optical switch are attached sequentially from the printing ink layer from bottom to top. Layer, electrode layer B, diffuse reflection layer and protective layer, the thickness of the display screen is not more than 5mm.

[0024] The printing layer adopts foldable and printable flexible insulating materials, such as paper, plastic, cloth, etc. Ink is printed on the printing layer to generate CMYK color ink dot matrix to obtain a printing ink layer.

[0025] The light-transmitting layer adopts a flexible light-transmitting material, such as ETEE (ETEE is a copolymer of tetrafluoroethylene and ethylene) plastic film, PET plastic film or shadowless glue, which is used to increase the distanc...

Embodiment 2

[0031] The bottom layer of the printed flexible display screen provided in this embodiment is the printing layer, and the printing ink layer is attached to the printing layer, and the light-transmitting layer, the substrate layer, the electrode layer A, and the electronically controlled optical switch are attached sequentially from the printing ink layer from bottom to top. Layer, electrode layer B and diffuse reflection layer, the thickness of the display screen is not more than 5mm. In this embodiment, the light-transmitting layer adopts shadowless glue, the diffuse reflection layer adopts varnish with diffuse reflection function, and the materials used in other layers are the same as those in Embodiment 1.

Embodiment 3

[0033] The bottom layer of the printed flexible display screen provided in this embodiment is the printing layer, the printing ink layer is attached to the printing layer, and the light-transmitting layer, the electrode layer A, the electric control optical switch layer, and the electrode layer are attached sequentially from the printing ink layer from bottom to top. B and protective layer, the thickness of the display screen shall not exceed 5mm. The materials used in each layer are the same as in Example 1.

[0034] The preparation process of the printed flexible display screen of the present invention is as follows:

[0035] (1) Use gravure printing to print ink on the printing layer to produce a CMYK color ink dot matrix, and obtain a printing layer with a printing ink layer attached. The process flow is: flexible substrate preparation → printing → adjustment rules → formal printing → printing Post-processing. The gravure printing machine has a high degree of automation,...

Abstract

The invention discloses a printed flexible display screen. The printed flexible display screen comprises a printed layer and a printing ink layer adhered to the printed layer, at least a transparent layer, an electrode layer A, an electric control photoswitch layer and an electrode layer B are adhered to the printing ink layer from bottom to top; the printed layer is made of a foldable and printable flexible insulating material, the printing ink layer is a CMYK (cyan, magenta, yellow and black) ink dot matrix printed on the printed layer, the transparent layer is made of a flexible transparent material, the electric control photoswitch layer is a PDLC (polymer dispersed liquid crystal) film, the electrode layer A and the electrode layer B are both ITO (indium tin oxide) conductive film layers respectively etched with an electrode matrix, and the electrode matrixes of the electrode layer A and the electrode layer B are vertical to each other. The display screen is easy to colorize, has the advantages of short response time, low driving voltage and low production cost and is suitable for reading with human eyes and in the manufacturing process is simple.

Description

technical field [0001] The invention relates to a printed flexible display screen, which belongs to the field of printing and also belongs to the field of electronics. Background technique [0002] The current display technology can be divided into two categories: one is paper display, its main features are: display content by reflecting ambient light, easy to display in color, large viewing angle (close to 180°), and soft medium. The other type is CRT, LCD, LED and other electronic displays. Its main features are: information can be refreshed quickly, relying on the internal light of the display itself to display the content, it needs to consume more power when working, it is easy to make people tired when reading, and the medium is not soft . [0003] In the past ten years, people are working hard to develop paper-like reflective flexible displays (commonly known as electronic paper), trying to overcome the shortcomings of the aforementioned two types of display technolog...
