Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.The utility model will
IC9 protects aspect independently of Electronic Paper, facilitates the edge sealing of product；PI protective layers and light shield layer in removal, or by PI layers and shading
Layer is incorporated into patterned layer 3；Eliminate patterned layer 3 structure excessively single inadequate diversity the drawbacks of；Improve display screen encapsulating structure.
It is specific as follows：
A kind of flexible electronic paper display screen, its structure are：Patterned layer 3, the patterned layer 3 are provided with flexible base board 7
On be provided with Electronic Paper module 2, unicom their linked hole 1 is provided between patterned layer 3 and Electronic Paper module 2；Described
The side of patterned layer 3 is additionally provided with golden finger 4；It is provided with Electronic Paper module 2 and protects its upper protective film 6, described soft
Property substrate 7 be arranged with protect its lower protective film 8；IC9 is fixed with the side of patterned layer 3, guarantor is provided with around the IC9
Protect the IC protection glue 10 of IC9.
As an improvement, also there is filled cavity 5 between upper protective film 6 and patterned layer 3.The upper protective film 6 and lower protection
Film 8 uses PET film.PI layers and light shield layer are integrated with the patterned layer 3.The patterned layer 3 is single layer metal firms or bilayer
The metallic stacked structure of metal structure or multilayer.The material of the flexible base board 7 is PET materials.
The utility model is exposed IC9 by shortening PET film, and such PET film is solved with regard to an overlay electronic paper region
The problem of IC9 ends thickness is blocked up.Air bubble problem caused by also solving IC9 ends clamping cavity at the same time.By IC9 it is individually designed go out
Come, then adhesion protection is carried out with IC protection glue 10.
PI layers in the utility model cancellation, process is reduced, reduces material cost.Light shield layer is reduced, process is reduced, reduces into
This.PI layers are incorporated into patterned layer 3 with light shield layer, can in a procedure complete design, save more processing procedure processes.
In the utility model, patterned layer 3 is single layer metal firms, may only show single pattern and picture effect.It is right
Patterned layer 3 carries out design：(1), PI layers and light shield layer are incorporated into inside patterned layer, reduce processing procedure process, and can
To be protected again to metallic circuit, steam is obstructed, prevents from corroding；(2), single layer metal firms are substituted for double-level-metal knot
Structure, centre insulating layer keep apart upper and lower double layer of metal, and needing, the region of conducting up and down is golden by two parts using via
Category is turned on；(3), the single layer metal firms of patterned layer 3 are also alternatively into the other metal laminated design of more layers, with insulation
Layer isolation, the design of via conducting, develop the other patterned layer 3 of more layers.
In the utility model, upper protective film 6 and lower protective film 8 and filled cavity 5 are added, Electronic Paper can be protected to show
Shield the erosion from materials such as extraneous water oxygens.Encapsulation design has had reached the PI layers of effect with light shield layer, and makes display screen
More integrality, therefore the PI layers of design with light shield layer can be saved.
In the utility model, kernel control module is mainly made of IC9 and IC protection glue 10, and IC9 receives exterior telecommunications
Number and be decoded into it is corresponding display signal output arrive display module, IC protection glue 10 main function be protect IC9 from outer
The erosion of boundary's material, and whole product ensure that IC9 does not occur to divide with flexible base board 7 and patterned layer 3 in the case of flexing
From.
Flexible base board 7 is the carrier of carrying patterned layer 3, and allows whole product to keep flexible main part,
Its material can be PET materials or other materials.
The effect of looking for of Electronic Paper package module is to protect whole Electronic Paper module 2 from the outer bound pair Electronic Paper such as extraneous water oxygen
The erosion of harmful material, upper protective film 6 mainly completely cut off the infringement for the material that upper strata is harmful to Electronic Paper, and lower protective film 8 is main
It is the erosion for completely cutting off lower floor to Electronic Paper harmful substance.Filled cavity 5 can fill material or gas to completely cut off from surrounding intrusion
Harmful substance, filled cavity are a complementary design protections, can not if the encapsulation of whole Electronic Paper module is all right
Designed with this device.
Linked hole 1 is responsible for the electrode designed on the ito thin film and patterned layer 3 of unicom Electronic Paper for it；Electronic Paper module 2 is negative
