Ultrathin windable segment-code-type electronic ink screen and preparing method

Abstract

The invention discloses an ultrathin windable segment-code-type electronic ink screen. The ultrathin windable segment-code-type electronic ink screen comprises a back-electrode base material, a back-electrode conductive thin film, an electronic ink layer, a front-electrode conductive thin film, frame glue, metal leads, a display driving IC and a front-electrode base material. The back-electrode conductive thin film is arranged on the back-electrode base material; the front-electrode conductive thin film is arranged on the front-electrode base material; the electronic ink layer is arranged between the back-electrode conductive thin film and the front-electrode conductive thin film; the frame glue is arranged between the back-electrode base material and the front-electrode base material; the display driving IC is arranged at one end of the back-electrode base material and connected with the back-electrode conductive thin film through the metal leads. According to the ultrathin windable segment-code-type electronic ink screen, a graphene thin film or a carbon-nano-tube thin film or a silver nanowire thin film serves as a transparent conductive material with low resistance and good light transmission and windable performance, the transparent conductive material can replace ITO in the segment-code-type electronic ink screen, and the windable performance of the electronic ink screen is achieved accordingly. The ultrathin windable segment-code-type electronic ink screen can be widely applied to the fields such as intelligent wearable devices, intelligent cards and electronic tags.

Description

technical field [0001] The invention relates to the field of electronic reading display screens, in particular to an ultra-thin bendable segment code electronic ink screen. Background technique [0002] E-ink screen is a green and environment-friendly non-active light-emitting flat-panel display device. Sexuality is the most basic requirement for making electronic ink screens have mechanical paper-like properties. However, the existing segment-code electronic ink screen electronic smart terminal products such as smart wearable devices, electronic tags, etc. are either not flexible, or have a certain degree of flexibility but the effect is not good, it cannot be bent, and it is not easy to use and carry. This has become the core bottleneck in the development of segment code electronic ink screen smart terminals. The electrodes in the existing electronic ink screens are all developed with hard materials (such as glass, ITO, etc.) as the core materials. [0003] For example,...

Problems solved by technology

At the same time, the transparent conductive material of the front electrode is ITO, which is a brittle material with poor flexibility and can only be bent at a small angle. A slight bending angle will break the ITO and cause the display function of the electronic ink screen to fail, and the ITO square resistance is very difficult to drive. , the light transmittance is low, so a transparent conductive material with low resistance, good light transmittance, and good flexibility is needed as a segment code electronic ink screen, so as to replace ITO to achieve the flexibility of the electronic ink screen
