Abstract
The utility model provides a hot-pressed type EPD flexible display screen with a PS protecting film. The EPD flexible display screen comprises an optical-grade waterproof film, an EP film and a TFT flexible glass substrate which are laminated in sequence, wherein the TFT flexible glass substrate is stuck to the EP film by hot-pressing and sticking a hot-melt adhesive layer; the optical-grade waterproof film is laminated with the EP film through a laminating machine drum. The EPD flexible display screen further comprises an IC processor and an FPC circuit board, wherein the IC processor and the FPC circuit board are connected with the TFT flexible glass substrate respectively, and are embedded between the TFT flexible glass substrate and the optical-grade waterproof film. According to the utility model, the TFT flexible glass substrate is substituted for an alkali-free glass substrate and can be bent by a certain angle; the optical-grade waterproof film is laminated with the EP film through the laminating machine drum; the IC is embedded between the TFT flexible glass substrate and the optical-grade waterproof film; the formed EPD display screen can be bent by a certain angle while the IC cannot be ejected out, so that the IC is protected; the EPD structure is compact and reasonable.
Description
Technical field
The utility model belongs to field of electronic display, particularly a kind of flexible electronic paper display screen.
Background technology
EPD display screen is a kind of display screen that utilizes electrophoretic display technology (EPD) and make.Electrophoretic display technology system is packaged in charged particle black, white dichromatism in microcapsule structure, by extra electric field, controlled the lifting moving of different electric charge black and white particles, to present the display effect of black and white monochrome, under the effect of electric field, two kinds of different particles of black and white are not stopped transport moving, and when white particle rises to upper surface, all ambient lightings are mapped to upper surface and are reflected completely, so just formed white state, namely the state of paper; After exchange electrode, the particle meeting switch of two kinds of colors, the particle of white just can be to having gone below like this, and above the particle of black is arrived, light is all absorbed by the particle of black, and result just causes black, has also just formed white and black displays.In addition, at upper surface, also can have the state of mixing, two kinds of proportional mixing of different particles, can form like this black and white and have the different colours of gray-level.Because EPD technology can present high reflectance, the high white and black displays effect contrasting, there is memory effect simultaneously, after extra electric field is cancelled, the demonstration that instant playback is current presented, the content as shown in same printed paper.Owing to thering is bistability, after power electrical field is cancelled, still image is retained to some months or several years on EPD.
As shown in Figure 1, it is comprised of glass substrate 101, EP film 102, optical grade waterproof membrane 103, IC processor 104, FPC wiring board 105 and frame glue 106 structure of existing EPD display screen.Glass substrate 101 adopts alkali-free glass, and glass substrate 101 pastes hot melt adhesive layer by hot pressing and EP film 102 is bonding; EP film 102 is comprised of ITO electrode film, electric ink capsule, hot melt adhesive layer.Optical grade waterproof membrane 103 is comprised of pet layer, OCA layer, water barrier, hot melt adhesive layer; Optical grade waterproof membrane 103 is by laminating machine cylinder and 102 pressings of EP film.IC processor 104 is connected with glass substrate 101, and FPC wiring board 105 is connected with glass substrate 101, and optical grade waterproof membrane 103, IC processor 104 and FPC wiring board 105 carry out encapsulation process by frame glue 106.
The problem of existing EPD display screen is: owing to adopting alkali-free glass, himself cannot be crooked, is therefore difficult to be applied to flexible EPD display screen, and IC fixes by frame glue, and after the crooked certain angle of EPD display screen, IC easily splits, PROCESS FOR TREATMENT imperfection.
Utility model content
Above-mentioned defect for existing EPD display screen; applicant is through Improvement; the box-like PS diaphragm of a kind of hot pressing EPD flexible display screen is provided; by adopting TFT flexible glass substrate; flexible certain angle; and optical grade waterproof membrane closes by laminating machine cylinder and EP mould, and while preventing bending, IC splits, and make the more compact structure of product reasonable.
The technical solution of the utility model is as follows:
The box-like PS diaphragm of a hot pressing EPD flexible display screen, comprises the optical grade waterproof membrane, EP film and the TFT flexible glass substrate that stack gradually; Described TFT flexible glass substrate pastes hot melt adhesive layer by hot pressing and EP film is bonding; Described optical grade waterproof membrane closes by laminating machine cylinder and EP mould; Also comprise IC processor and FPC wiring board, described IC processor is connected with TFT flexible glass substrate respectively with FPC wiring board, and is embedded between TFT flexible glass substrate and optical grade waterproof membrane.
Useful technique effect of the present utility model is:
The utility model is used TFT flexible glass substrate to substitute alkali-free glass substrate, flexible certain angle; Optical grade waterproof membrane closes by laminating machine cylinder and EP mould, and IC embeds between TFT flexible glass substrate and optical grade waterproof membrane, and the crooked certain angle IC of formed EPD display screen can not eject yet, protection IC; The structure that the utility model makes EPD is compact and reasonable more.
Accompanying drawing explanation
Fig. 1 is the sectional structure chart of existing EPD display screen.
Fig. 2 is sectional structure chart of the present utility model.
Fig. 3 is the sectional structure chart of optical grade waterproof membrane.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 2, the EPD display screen that the utility model is comprised of the optical grade waterproof membrane 203 stacking gradually, EP film 202 and TFT flexible glass substrate 201.TFT flexible glass substrate 201 pastes hot melt adhesive layer by hot pressing and EP film 202 is bonding.Optical grade waterproof membrane 203 is by laminating machine cylinder and 202 pressings of EP film.FPC wiring board 205 is connected with TFT flexible glass substrate 201.IC processor 204 is connected with TFT flexible glass substrate 201.FPC wiring board 205, IC processor 204 are all embedded between TFT flexible glass substrate 201, optical grade waterproof membrane 203.EP film 202 is comprised of ITO electrode film, electric ink capsule, hot melt adhesive layer.TFT flexible glass substrate 201 can crooked certain angle, to protect IC processor 204, prevents that IC processor 204 is ejected.
As shown in Figure 3, optical grade waterproof membrane 203 is mainly comprised of pet layer, OCA layer, water barrier, hot melt adhesive layer.Optical grade waterproof membrane 203, by lamination, because the thermal insulation of plastics is fine, heats its surperficial hot melt adhesive layer, by laminating machine cylinder and EP film 202, presses together.In the present embodiment, the model that optical grade waterproof membrane 203 adopts is FLEXguard03081002.Optical grade waterproof membrane 203 energy ultraviolet ray filterings, and have extraordinary moisture resistance and transparency.
