Print type flexible contact display screen based on resistance effect

Abstract

The invention discloses a print type flexible contact display screen based on a resistance effect. The print type flexible contact display screen comprises a printing layer, a print ink layer, a light transmitting layer, an electrode layer A, an electric control photo switch layer, an electrode layer B, an isolation layer, an electrode layer C and a substrate layer C, wherein the printing layer is foldable and is made of a printable flexible insulation material; the print ink layer is a CMYK (Cyan, Magenta, Yellow, black) ink dot matrix printed on the printing layer; the light transmitting layer is made of a flexible light transmitting material; the electric control photo switch layer is a PDLC (polymer dispersed cholesteric texture) film; the isolation layer is a hollow flexible transparent latticed film; the substrate layer C is a flexible transparent organic film; the electrode layer A, the electrode layer B and the electrode layer C are ITO (indium tin oxide) films printed with electrode matrixes; and the matrix direction of the electrode layer A is the same with that of the electrode layer C, and the matrix direction of the electrode layer A is vertical to that of the electrode layer B. The display screen provided by the invention has a contact function, is short in response time, low in drive voltage, simple in production technology and low in production cost.

Description

technical field [0001] The invention relates to a printed flexible touch display screen based on resistance effect, 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 aforemention...

AI Technical Summary

Problems solved by technology

[0005] 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.
