Specific embodiment

For the ease of the understanding of those skilled in the art, further is made to this utility model with reference to embodiment and accompanying drawing Explanation, the content that embodiment is referred to is not to restriction of the present utility model.

As shown in figure 1, a kind of flexible electronic shows cover plate, including flexible film substrates 1, flexible optical thin slice 2, flexible thin The lower surface of film base material 1 coats one layer of transparency conducting layer 3 resistant to bending, the upper surface or flexible optical of flexible film substrates 1 The lower surface of thin slice 2 coats one layer of optical cement layer 4, and flexible film substrates 1 are fitted with flexible optical thin slice 2 by optical cement layer 4 Together.

The flexible electronic that above-described embodiment is provided shows cover plate using flexible film substrates 1 and the conduct of flexible optical thin slice 2 Substrate, by the upper surface in flexible film substrates 1, directly one layer of optical cement layer 4 of coating fits it with flexible optical thin slice 2 To together, it is to avoid the situation of full laminating is manually carried out using OCA two-sided tapes in rear processing workshop section（Using OCA two-sided tapes Carrying out full laminating needs first OCA two-sided tapes to be cut into into the shape of regulation, and this can cause adhesive tape to waste, and need during laminating By adhesive tape precise positioning, laminating speed is slow, it is more to expend man-hour）, reduce the waste of man power and material；In this utility model, Because flexible film substrates 1 and flexible optical thin slice 2 are flexible material, coordinate transparency conducting layer 3 resistant to bending, make Obtain the flexible electronic and show that cover plate is suitable for the application of flexible and curved-surface display.

In the above-described embodiments, it is preferred that flexible film substrates 1 be PET mylars, the PET mylar light transmittances >=91%, thickness is 36-100 microns.PET mylars are widely used in electronical display sector application, for its advantage here not Repeat, the PET mylars of selection light transmittance >=91% are mainly based upon the consideration of whole cover plate light transmittance, and thickness is 36- 100 microns of PET mylars can meet lightening requirement and in turn ensure that laminating workability, when PET polyester thickness When degree is less than 36 microns, it is larger with the operation difficulty of fitting of flexible optical thin slice 2.Although PET mylars are thicker, laminating behaviour It is more convenient to make, but the thickness increase for thus bringing obviously is not inconsistent with the lightening trend of electronic product, therefore by PET polyester thickness It is preferably to select that degree is limited to the scope of 36-100 microns.

In the above-described embodiments, it is preferred that transparency conducting layer 3 is in nano-silver thread layer, graphene layer, carbon nanotube layer Conductive layer that is a kind of or being optional two kinds and above Material cladding from nano-silver thread, Graphene, CNT.More than Material is to make the more common material of nesa coating resistant to bending, and more typical uses for single, and applicant Jing experiments find, Nano-silver thread and Graphene are combined（For example with many of nano-silver thread-Graphene or nano-silver thread-Graphene-nano-silver thread Layer composite construction）Nesa coating light transmittance and electric conductivity can be carried to higher level, and its is saturating under bending state The change that light rate and electric conductivity not can detect that, but it is high using the conductive layer cost of above-mentioned material making, it is current difficult With popularization and application.

Based on the consideration that Cost And Performance is balanced, it is preferred that transparency conducting layer 3 adopts PEDOT or PEDOT：PSS material systems Into.PEDOT and PEDOT：The conductive layer bending resistance that PSS materials make is good, but sheet resistance is big, is not suitable for making large-sized aobvious Show cover plate, applicant Jing repeatedly practises discovery, in PEDOT or PEDOT：PSS materials mix nano-silver thread as conductive reinforcement, lead After electric layer solidification, nano-silver thread and PEDOT or PEDOT：PSS forms cross-linked network, and this kind of structure can be greatly reduced and lead The sheet resistance of electric layer simultaneously can improve conductive layer electric conductivity in the bent state, and the overall performance of this kind of structure can about reach aforementioned The 80% of composite conductive layers, and cost is only its half or so.

Additionally, in the above-described embodiments, optical cement layer 4 is preferably made using the acrylic optical glue of semi-cured state, Aforesaid propylene acid optical glue can pass through UV photocurings.It should be noted that in the above-described embodiments, optical cement layer 4 can also It is to be fully cured acrylic optical glue, practice finds, the glue-line of semi-solid preparation is more easy to row's bubble when flexible optical thin slice 2 is fitted, And again by illumination by its all solidstate after the completion of laminating, therefore light is made using the acrylic optical glue of semi-cured state Learning glue-line 4 can allow follow-up laminating process row's bubble more convenient, thorough, be conducive to improving work efficiency of fitting.Furthermore it is also possible to Add for absorbing wavelength for the blue-light absorbers of 430-470nm blue lights and for absorbing in aforesaid propylene acid optical glue Wavelength is the UV absorbers of 280-400nm ultraviolet lights, in mass, the addition of blue-light absorbers and UV absorbers Preferably 0.5-3%.Add above-mentioned blue-light absorbers and UV absorbers can be so that the electronical display cover plate possesses uv blocking light With blue light function, be conducive to protecting vision, during actual production, the blue-light absorbers of addition coordinate preferably with steady moral TM47 in Europe The steady moral TM47 blue-light absorbers in Europe, UV absorbers are preferably with BASF UV-400 UV absorbers and ultraviolet absorber UV-234 presses 2：3 mass ratio compounding is formed, and the blue-light absorbers and UV absorbers of above-mentioned compounding can ensure that glue-line is saturating Light rate to the absorbance of high energy ultraviolet light wave more than 75%, and may filter that 40% or so harmful blue light more than 85%.

In above-mentioned flexible electronic shows cover plate, as shown in figure 1, flexible optical thin slice 2 is the case hardened place of upper surface Reason is formed with the PET thin slices or PC thin slices or PMMA thin slices of wear-resistant hardened layer 2a.Make surface in the upper surface of flexible optical thin slice 2 hard Change process forms wear-resistant hardened layer 2a and can improve its wear-resistant scratch resistant performance, and be conducive to prolongation display cover plate normally uses the longevity Life.Finally, the flexible electronic shows that the gross thickness of cover plate is preferably 0.2-2mm.

Above-described embodiment is this utility model preferably implementation, and in addition, this utility model can be with other sides Formula realizes that any obvious replacement is in protection model of the present utility model on the premise of conceiving without departing from the technical program Within enclosing.

In order to allow those of ordinary skill in the art more easily understand this utility model relative to prior art improvement it Place, some accompanying drawings of the present utility model and description have been simplified, and for the sake of clarity, present specification is omitted one A little other elements, those of ordinary skill in the art should be aware that these elements for omitting also may make up in of the present utility model Hold.
