Embodiment 1

[0045] Electrophoretic electronic ink technology is commonly referred to as electronic ink (electronic ink). Electronic ink is coated on a layer of plastic film, and then coated with a thin film transistor (TFT) circuit, which is controlled by a driver IC to form a pixel pattern, creating an electronic paper display (Electronic Paper Displays, EPD). Due to its low power consumption and good sunlight readability, electronic paper displays have been widely used in electronic reading, electronic labels, billboards and other fields in recent years. features. Compared with liquid crystal display (LCD), since the electronic paper display does not need to align the electrophoretic particles, the display is realized by the movement and reflection of the electrophoretic particles between the two electrodes. Therefore, the electronic paper display is easier to display. Applied to flexible displays.

[0046] Due to the characteristics of the electronic paper film, it is relatively sens...

Embodiment 2

[0057] This embodiment provides an electronic device, including the electronic paper packaging structure provided in the above embodiments. The electronic device has better effect of blocking water and oxygen. The electronic device may be a flexible electronic paper device.

Embodiment 3

[0059] This embodiment provides a method for encapsulating electronic paper. In one embodiment, the method includes the following steps:

[0060] Set electronic paper film on TFT substrate;

[0061] An inorganic layer with high light transmittance and high density is arranged above and around the electronic paper film.

[0062] In the electronic paper packaging method provided in this embodiment, since the inorganic layer is arranged above and around the electronic paper film, the inorganic layer has high light transmittance, which will not affect the normal display function, and at the same time, the inorganic layer has high density and can effectively isolate water vapor. Prevent water and oxygen from entering the interior of the product, thereby avoiding the oxidation reaction of the ink and avoiding device failure. At the same time, compared with the prior art, it can replace the edge sealing glue.

[0063] On the basis of the above embodiment, in a preferred embodiment,...

Abstract

The invention relates to the technical field of electronic paper, in particular to an electronic paper packaging structure, a packaging method and an electronic device. Theelectronic paper packaging structure comprises: a TFT substrate; an electronic paper film, arranged on the TFT substrate; and an inorganic layer with high light transmittance and high compactness, arranged above and around the electronic paper film. Due to the fact that the inorganic layer is arranged above and around the electronic paper film, the inorganic layer has high light transmittance and high compactness, the normaldisplay function is not affected, meanwhile, the inorganic layer has high compactness, water vapor can be effectively isolated, water and oxygen are prevented from entering a product, oxidation reaction of printing ink is avoided, and device failure is avoided. Meanwhile, compared with the prior art, edge sealing glue can be replaced.
