Description
Technical field
The invention belongs to photoelectric display field more particularly to a kind of flexible electronic paper display devices and its system for having ink layer
Make method.
Background technique
Electronic Paper has many advantages such as that reflected light shows nature, flexible, is easy to inexpensively manufacture and low-power consumption.With
Other display technologies are compared, and the reflectivity and contrast of Electronic Paper are preferable, are to be suitble to people's wearing and outdoor display
Media, and in the case where light includes direct sunlight, the display equipment based on Electronic Paper can still provide for normally using, therefore wide
It is general be applied to price tag is shown, IC card is shown, on all kinds of intelligent terminals and wearable device.
Electronic paper display product in the prior art is based on the rigid electronic paper screen of glass base, deflection electronics flexible
Paper screen is rarer.In recent years, the development of flexible electronic paper display technology is very rapid, and various advanced manufacture crafts and technology are not
It is disconnected to emerge in large numbers, so that flexible electronic paper shows that quality is continuously improved.Electronic paper display panel 120 in the prior art, as the U.S. is special
Illustrated by sharp US7123238 and Chinese patent CN101311808A, as shown in Figure 1, its structure generally includes band from bottom to top
There are driving backboard 101, the electrophoretic ink layer 102, the upper substrate 103 with public electrode of driving electrodes.Wherein electrophoretic ink layer
102 constitute display front plate 110 with the upper substrate 103 with public electrode, and electrophoretic ink layer 102 usually has according to different specifications
5~300 microns of thickness, and the plastic base of different-thickness then can be used in the upper substrate 103 with public electrode, thickness can
To there is 30~300 microns, and in actual production application, it is contemplated that the various reasons such as manufacture craft, driving backboard 101
Size is usually larger than display front plate 110, and there are one which results in display front plate 110 and driving 101 neighboring area of backboard
A biggish height offset, i.e. the height offset of display area and non-display neighboring area.
In addition, flexible electronic paper screen is configured between terminal device and cover board, when arranging in pairs or groups with terminal device due to flexibility
The inherent characteristic of deflection material, both mechanical performance and display quality must be properly settled simultaneously.Many patents exist
When the mechanical performance for improving flexible display screen, ignore or weaken its display quality.Chinese patent CN201210208465.7
Devise back support mode, though impact resistance can be improved to a certain degree, poor seismic behavior, be easy to cause screen deviate or
Inclination influences to show quality, is unfavorable for market application.Chinese patent CN201210208465.7, CN201110084898.1 take off
In the patent structure shown, there is certain gap between display screen and cover board, on the one hand which is easily accessible dust, influence
Display effect；On the other hand clearance distance between the two is difficult to control uniformly, under the catadioptric effect of ambient light, is easy
Interference fringe is generated, screen is seriously affected and shows quality.On the other hand, since flexible electronic paper display device has spy flexible
Sign, after being arbitrarily bending or folding over for people, if curved transitions, or the curved transitions in equipment Assembling Production, it will
Lead to device stress deformation, internal display dielectric layer is damaged or even the separation of each component, final to influence display effect and use
Service life.Chinese patent CN201010518104.3 discloses the curve flexibility display screen of complicated encapsulating housing, it is intended to
This solves the mechanical performance and display quality of flexible screen to improve, but this method complicated in mechanical structure, manufacturing method be complicated and material
Expect that consumption is big, product yield and cost are also difficult to control.
In summary problem, as shown in Fig. 2, inventor attempts to be bonded using optical clear glue-line 204 in R&D process
Cover board 205 and flexible electronic paper display panel 220, fill gap while improving structural stability, prevent dust etc. other
The entrance of interfering substance, but since display front plate 210 and driving 201 neighboring area of backboard are there are height offset, with cover board 205
Still gap can be formed in periphery when combination, after being bonded using optical clear glue-line 204, easily be formed in this circumferential play big
Measure bubble 206, it is difficult to remove, and since driving backboard 201 has elasticity, be easy to produce that deaerator all not can be removed " extremely
Bubble ", by being iteratively improved manufacturing process, even if eliminating bubble by squeezing during fitting, but due to driving backboard 201
With certain elasticity, it is likely to occur driving backboard rebound phenomenon after deaeration solidification, and regenerates a large amount of bubbles, 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 for having ink layer
Method guarantees the solid and reliable of structure, and does not influence the display quality of flexible electronic paper display screen, solves the interference of bubble, provides
A kind of good appearance, excellent performance, easily fabricated and long-lived flexible electronic paper display device.
