[0002] As new energy vehicles are developing vigorously, car key cards are favored by many car manufacturers due to their intelligence and portability, and the demand for unique and technological appearance is also increasing.

[0003] Due to the limitations of card bending and twisting and card toughness standards, domestic LED light source card products all use point light sources to achieve the point lighting effect when the card is swiped. Surface light source card products on the market are very rare, and are generally implemented with hard PCB circuit boards, which are not resistant to bending and have high costs.

[0004] In order to fill the gap in domestic smart card surface light source products, compared with the high cost of single surface light source cards in overseas markets, facing the rapid development of the new energy vehicle field, there is an urgent need for a new smart card that can be used as a car key card. While achieving the surface lighting effect, it improves the card's bending resistance and significantly reduces production costs. Utility Model Content

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0031] A specific embodiment of the utility model is as follows Figure 1-2 , discloses an LED surface lighting smart card, the smart card includes an INLAY layer 1 located in the middle layer and a printed layer 2 and a protective film layer 3 symmetrically arranged on both sides of the INLAY layer, wherein the INLAY layer includes a first protective layer 4, a first compensation layer 5, a buried wire layer 6 and a second protective layer 7 stacked in sequence; an LED point light source is provided on the chip of the buried wire layer 6; a PC light guide area 10 matching the size of the LED point light source area is provided at a position corresponding to the LED point light source area on the first protective layer 4; components other than the point light source on the chip are wrapped with black glue to form a non-contact module 8 and an LED light module 9.

[0032] It should be noted that the smart card of the present invention includes a standard card and a special-shaped card.

[0033] It should be noted that, according to the area where the smart card needs to emit light, the utility model uses sequential arrangement on the chip (such as Figure 2 The surface lighting effect of the smart card of the utility model is completely different from the point lighting effect achieved by the existing smart card through the point light source, and is the same as the surface lighting effect achieved by the surface light source in the prior art. The number of point light sources can be determined according to the size of the point light source, the chip size, the area, shape and brightness of the light-emitting area, and is generally 3-100.

[0034] It should be noted that the utility model can also realize double-sided illumination of the smart card. The specific solution is that, based on the above-mentioned single-sided illuminating smart card, a second compensation layer is further included between the buried wire layer and the second protective layer. The chip of the buried wire layer is also provided with an LED point light source on the side in contact with the second compensation layer. A light guide area matching the size of the LED point light source area is also provided at the position corresponding to the LED point light source area on the second protective layer 7.

[0035] It should be noted that in order to emit light in a limited area, the utility model needs to set an ink layer outside the INLAY layer to cover the area that does not need light leakage; in addition, because the light brightness at the point light source position and a certain range around it is uneven, it is also necessary to use ink to cover the area adjacent to the point light source position, so that after the point light source is specially arranged, the area with uniform light corresponds to the area that needs light transmission; wherein, the ink layer needs to meet a certain shading effect and ensure that no imprint appears when making the card. Specifically, the thickness of the ink layer described in the utility model is 0-500μm, such as 20μm, 60μm, 100μm, 200μm, 300μm, 400μm, 500μm.

[0036] It should be noted that the point light sources need to be arranged in sequence on the chip according to the shape of the light-emitting area to ensure the brightness and uniformity of the light-emitting area of ​​the smart card.

[0037] It should be noted that in order to make the specially arranged point light sources have a good surface lighting effect and avoid halo and uneven light transmission, the light from multiple point light sources needs to be transmitted to the surface of the smart card through the light guide area.

[0038] The utility model limits the light transmittance of the PC light guide layer to the range of 60-100%. If the light transmittance is too high, uneven light brightness will be caused; if the light transmittance is too low, insufficient light brightness will be caused.

[0039] According to a specific implementation of the utility model, 14 point light sources are used as follows: Figure 2The special arrangement shown achieves a uniform surface lighting effect through the light transmittance of the PC light guide area and the covering of the area where no light leakage is required by ink. The surface lighting effect of the smart card of the utility model is completely different from the point lighting effect achieved by the existing smart card through the point light source, and is the same as the surface lighting effect achieved by the surface light source in the prior art.

[0040] It should be noted that the smart card of the utility model further comprises a printing layer and a protective film layer which are symmetrically arranged on both sides of the INLAY layer in sequence.

[0041] It should be noted that the pattern on the printing layer of the utility model is generally printed with hollowing or light-color printing at the light source; the protective film layer is a light-transmitting film layer, generally made of PVC material.

[0042] According to a preferred specific embodiment of the utility model, the ink layer is arranged outside the first protective layer and / or the second protective layer. More preferably, the ink layer is arranged on the surface of the printing layer facing the INLAY layer.

[0043] It should be noted that the protective film layer, the printing layer and the INLAY layer of the utility model are bonded together by an adhesive.

[0044] Furthermore, a printed pattern layer is included between the protective film layer and the printed layer, and the required pattern and gun card line are offset printed on the printed layer by adhesive through offset printing, and the protective film layer and the printed layer are bonded.

[0045] Furthermore, the light-shielding ink is screen-printed on the printing layer between the printing layer and the INLAY layer by screen printing, and the printing layer and the INLAY layer are bonded together.

[0046] It should be noted that, through the special arrangement of point light sources, the light transmittance of the light guide area and the covering of the ink, the utility model can realize light emission of different patterns and different size areas at different positions on the entire surface of the smart card.

[0047] According to a specific implementation of the present utility model, the size of the luminous area of ​​the smart card is 16×14 mm.

[0048] Another specific embodiment of the present utility model discloses a car key card, and the car key card is the smart card described in the above specific embodiment.

[0049] According to the bending and twisting test method in the national standard GB / T17554, the LED surface lighting smart card provided by the utility model was tested using a bending and twisting tester, and it was found that the smart card of the utility model functioned normally after 2000 times of dynamic bending and twisting; compared with the prior art, under the same test conditions, the LED surface light source card in comparative example 2 could not be used normally after 2000 times of dynamic bending and twisting.

[0050] The ink forming the ink layer is an existing light-shielding silk screen ink, for example, an ink purchased from Zhongshan Moerjia.

[0051] Example 1

[0052] The LED surface lighting smart card 1 includes: an INLAY layer located in the middle layer, and a PET printing layer and a PVC protective film layer symmetrically arranged on both sides of the INLAY layer. Among them, 14 point light sources are arranged on a single side of the INLAY layer chip. Figure 2 The special arrangement shown in the figure passes through the PC light-guiding area and then is blocked by the ink layer on the lower surface of the PET printed layer facing the INLAY layer. When the card is read, a light-emitting area is lit on the surface of the smart card, wherein the light transmittance of the PC light-guiding area is 85%.

[0053] According to the bending and twisting test method in the national standard GB / T17554, the bending resistance performance of the face-lit smart card 1 was tested. The test results show that the smart card 1 can still be lit and used normally after 2000 times of dynamic bending and twisting.

[0054] Comparative Example 1

[0055] A commercially available point light source smart card 2 is provided, wherein the number of the point light sources is 2.
