Description
Technical field
The invention belongs to photoelectric display field, particularly relate to a kind of flexible electronic paper display device having ink layer and system thereof
Make method.
Background technology
Electronic Paper has reflection light display nature, flexible, be prone to inexpensively to manufacture and many advantages such as low-power consumption.With
Other Display Technique is compared, and the reflectance of Electronic Paper and contrast are preferable, is to be suitable for people to dress and outdoor display
Media, and under light includes direct sunlight, display device based on Electronic Paper can still provide for using normally, therefore by extensively
General it is applied to that price tag shows, IC-card shows, on all kinds of intelligent terminal and wearable device.
Electronic Paper of the prior art display product is based on the rigid electronic paper screen of glass base, flexible deflection electronics
Paper screen is rarer.In recent years, the development of flexible electronic paper Display Technique is very rapid, and the processing technology of various advanced persons and technology are not
Break and emerge in large numbers so that flexible electronic paper display quality improves constantly.Electronic paper display panel 120 of the prior art, as the U.S. is special
Illustrated by profit US7123238 and Chinese patent CN101311808A, as it is shown in figure 1, its structure generally includes band from bottom to top
Have drive electrode drives backboard 101, electrophoretic ink layer 102, upper substrate 103 with public electrode.Wherein electrophoretic ink layer
102 constitute display front plate 110 with the upper substrate 103 with public electrode, and electrophoretic ink layer 102 generally has according to different specifications
The thickness of 5～300 microns, then can use the plastic base of different-thickness with the upper substrate 103 of public electrode, and its thickness can
There to be 30～300 microns, and in actual production application, it is contemplated that each side reasons such as processing technology, drive backboard 101
Size is generally larger than display front plate 110, and which results in display front plate 110 and drive backboard 101 neighboring area existence one
Individual bigger height offset, i.e. viewing area and the height offset of non-display neighboring area.
It addition, flexible electronic paper screen is when arranging in pairs or groups with terminal unit, it is configured between terminal unit and cover plate, due to flexibility
The inherent character of deflection material, its mechanical performance and display quality must be properly settled simultaneously.Many patents exist
When improving the mechanical performance of flexible display screen, ignore or weaken its display quality.Chinese patent CN201210208465.7
Devise back support mode, though impact resistance can to a certain degree be improved, but poor seismic behavior, be easily caused screen skew or
Tilt, affect display quality, be unfavorable for that market is applied.Chinese patent CN201210208465.7, CN201110084898.1 take off
In the patent structure shown, all there is certain gap between display screen and cover plate, on the one hand this gap is easily accessible dust, impact
Display effect；Clearance distance the most between the two is difficult to control to uniformly, under the catadioptric effect of ambient light, easily
Produce interference fringe, have a strong impact on screen display quality.On the other hand, due to flexible electronic paper display device, there is the spy of flexibility
Levy, for people random be bending or folding over after, if curved transitions, or the curved transitions when equipment Assembling Production, will
Causing device stress deformation, its internal display dielectric layer is impaired, and the most each isolation of components finally affects display effect and makes
Use the life-span.Chinese patent CN201010518104.3 discloses the curve flexibility display screen of baroque encapsulating housing, it is intended to
Improve with this and solve the mechanical performance of flexible screen and display quality, but the method complicated in mechanical structure, manufacture method are complicated and
Consumption of materials is big, and product yield and cost are also difficult to control to.
Summary problem, as in figure 2 it is shown, inventor attempts using optical clear glue-line 204 to fit in R&D process
Cover plate 205 and flexible electronic paper display floater 220, fill gap while improving structural stability, prevent dust etc. other
The entrance of interfering material, but owing to display front plate 210 exists height offset with driving backboard 201 neighboring area, with cover plate 205
Still can be in formation gap, periphery during combination, after using optical clear glue-line 204 laminating, easily formed big in this circumferential play
Amount bubble 206, it is difficult to remove, and owing to driving backboard 201 to there is elasticity, it is " dead that easy generation deaerator all cannot be removed
Bubble ", by being iteratively improved manufacturing process, even if eliminating bubble by extruding during laminating, but owing to driving backboard 201
Having certain elasticity, be likely to occur driving backboard rebound phenomenon, and regenerate a large amount of bubble after deaeration solidifies, this can be tight
Ghost image rings the visual experience of user, damages product quality.
In view of this, it is necessary to propose new construction and the manufacturer of a kind of flexible electronic paper display device having ink layer
Method, it is ensured that structure solid and reliable, does not the most affect the display quality of flexible electronic paper display screen, solves the interference of bubble, it is provided that
A kind of good looking appearance, excellent performance, it is easy to manufacture and long-lived flexible electronic paper display device.
