Problems solved by technology

[0003] As far as people's living habits are concerned, pure electronic display screens cannot meet people's requirements. There are also electronic ink touch screens on the market, such as Amazon's kindle e-books.
However, the existing touch panel and the electronic ink display are separated. If the touch panel is placed outside the electronic ink in the original way, there is a physical space between the electronic ink display and the touch panel. Therefore, on the electronic ink display External light, etc. is reflected between the touch panel and the bottom of the touch panel, resulting in poor visibility in bright environments such as outdoors

[0032] The electronic display ink touch screen includes a substrate 1 (hardened layer), a thin film conductive layer 2, an electronic ink layer 3, a touch layer 4, an electrode pixel layer 5 and a substrate material 6; the electrode pixel layer is arranged on the substrate; the A touch layer is arranged on the electrode pixel layer; an electronic ink layer is arranged on the touch layer; a thin film conductive layer is arranged on the electronic ink layer; a base material is arranged on the thin fi...

Embodiment 2

[0040] This embodiment proposes a method for preparing an in-cell electronic ink touch display screen. This embodiment adopts in-cell technology to embed the touch panel into the electronic display screen, so that the original external touch panel components and electronic ink display The panel is integrated, and the unique structure of the electronic ink touch screen makes the screen thinner and lighter; the specific steps are as follows:

[0041] Combining the flexible TFT with the substrate section to form a TFT substrate;

[0042] transfer graphene onto the surface of the TFT substrate;

[0043] Print silver paste on the edge of graphene;

[0044] Design circuit by laser etching TP;

[0045] Fix the FPC on the TFT substrate by binding;

[0046] Transfer the graphene onto the PET substrate with a hardened protective layer;

[0047] Coating electronic ink on PET substrate and then baking electronic ink;

[0048] Glue was coated on the PET substrate to synthesize the TFT...

Abstract

The invention discloses an in-cell electronic ink touch display screen comprising a touch panel and an electronic display screen. The touch panel is arranged in the electronic display screen, and the touch panel parts and an electronic ink display panel are integrated into an electronic ink touch display screen structure. The electronic ink display screen of the invention is closer to the visual angle of 180 degrees, and the readability is enhanced. The touch panel is embedded into the electronic display screen, the number of layers that light needs to pass through is reduced, and the image resolution is enhanced. Through touch panel embedding, the time for bonding the layers of the display screen is reduced, and the production efficiency is increased. The display screen is thinner and more flexible, and the screen space is enlarged. Space can be found for a larger battery or other more abundant auxiliary equipment.

Description

technical field [0001] The invention relates to the field of electronic reading display screens, in particular to an in-cell electronic ink touch display screen and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of science and technology, people can enjoy new reading methods such as new media services, electronic newspapers and periodicals, and QR code reading through terminals such as computers, digital TVs, mobile phones, and tablet computers. The emergence of e-books has attracted great attention, especially e-books in electronic ink. This kind of e-book can provide a texture and reading experience similar to traditional books, making the eyes less prone to fatigue; at the same time, e-ink emits color by reflecting natural light, and the screen will not reflect light even under strong light Indistinct situation. And this kind of e-book no longer needs to consume more electricity, only consumes electricity when swi...
