Step 101, according to the window ranges of pre-set dimension, forms the base material that has window.
Fig. 2 is the schematic diagram with the base material of window in the present embodiment, as shown in Figure 2, has a window 11 on the base substrate 12.
For the topsheet of the sheet material in the present embodiment needed for the smart card with display, the topsheet for smart card is needed to design the region can seeing internal display, in order to realize this region, first the base material that has window can be formed, window is a through hole, the shape and size of window can set according to the shape and size of internal display, and when such as internal display is rectangular display, window also can be designed to rectangle adaptively.Certainly, even be applied to field of intelligent cards, window in the present embodiment is also not limited to for through seeing this certain device of display, also can for needing to see other regions of smartcard internal or other types device and designing this window, when the pilot lamp such as LED are such as set in smartcard internal, also window can be set in the corresponding position of base material, see the signal of pilot lamp to allow user through this window.
The base material that above-mentioned formation has window can utilize the mode of injection moulding directly to be formed, and namely utilizes injection mold to adopt the method for injection moulding directly to form base material with window.Also can, according to the window ranges of pre-set dimension in base substrate, the cutting methods such as stamping-out be utilized to cut out satisfactory window.
Base material in this step can be the blank substrates of the non-printed patterns in surface and word, also can be surface printed patterns or word " printing element " (namely surface is printed on the base material of pattern or word).The color of base material includes but not limited to white, Transparent color etc.The material of such as base material can be selected from the one in PET (polyethylene terephthalate), PETG (polyethylene terephthalate-1,4-CHDM ester), ABS (acrylonitrile-butadiene-styrene copolymer) or PHA (polyhydroxyalkanoate).
Step 102, provides the window patch that size and described window size adapt.
Still for the application scenarios of smart card, user can be allowed through seeing the inner region or the device that need displaying by the window 11 on base material 12, but the problem brought thus is window 11 place belongs to void region, after this base material 12 and other synusia material of smart card are carried out pressing, to occur obviously in uneven thickness at window 11 place, i.e. collapse phenomenon.Utilize window patch the hollow out of this part to be filled, to reduce difference in height in the embodiment of the present invention for this reason.
The thickness of window patch can be less than or equal to the degree of depth of the window of base material, those skilled in the art should be understood that, when the thickness of window patch equals the window degree of depth of base material (window patch 21 as shown in Fig. 3 A), the problem of planarization can be solved completely, and when the thickness of window patch is less than the window degree of depth of base material (window patch 21 ' as shown in Fig. 3 B), the problem of planarization can be improved to a certain extent.
Certainly, the shape and size of window patch also adapt with the window shape of base material and size, and when the window of such as base material is rectangular shape, the shape of window patch also respective design is rectangle.
The supplying method of the window patch in step 102 can be the window patch directly providing size and window to adapt; Also can be utilize the cutting methods such as stamping-out on bandage substrate, cut out the window patch that size and window adapt, such as, position punch equipment can be utilized according to predetermined technological parameter, go out the window patch 21 of pre-set dimension.
