Description

Technical Field

[0001] The utility model relates to the technical field of electronic paper displays, and in particular to a novel electronic price tag structure. Background Art

[0002] With the electronic update of retail places such as supermarkets and pharmacies, electronic price tags have gradually replaced paper price tags. At present, the display screens used in various places are divided into two categories, one is TFT price tags and the other is electronic paper price tags. TFT price tags require long-term power supply to display pictures and need to be equipped with backlights. The larger the size of the TFT price tag itself and the required backlight consume more power. With the call of the country to achieve carbon neutrality and carbon peak, electronic paper price tags have emerged as one of the best. The display screen used by electronic paper price tags is an electronic ink screen. The electronic ink screen changes the electric field to make the internal charged particles move, so as to display the picture required by the customer. The electronic ink screen does not need to be continuously powered on and can display the picture when the power is off, which is more energy-saving and environmentally friendly. The electronic paper price tag is composed of an electronic ink screen with a driver board, a button battery, a cover and a shell.

[0003] In the process of implementing this solution, the inventors discovered that the following problems in the prior art have not been well solved: the current electronic paper price tags are made by attaching a cover plate to the surface of the electronic paper display screen. The attachment of the cover plate will reduce the size of the viewing area. The cover plate and the electronic paper display screen are edge-to-edge, with a gap in the middle. This not only makes the overall thickness of the price tag thicker, but also causes scattering. Because the cover plate surface is smooth, the contents of the display screen can be clearly displayed, but the smooth surface will cause a reflective effect. Utility Model Content

[0004] The main purpose of the present utility model is to provide a new electronic price tag structure. By using a double-layer PS waterproof film for full lamination, the outer PS waterproof film replaces the cover plate, and double lamination of the PS waterproof film is performed to realize a new electronic price tag structure. Not only can full lamination be achieved without any reduction in the viewing area of ​​the electronic paper display, but there is also no gap, no increase in the overall price tag thickness, no scattering, and no reflection, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A novel electronic price tag structure includes an electronic paper TFT backplane, an electronic paper membrane, an internal PS waterproof film, an adhesive, and an external PS waterproof film. The electronic paper TFT backplane is laminated with the electronic paper membrane, the internal PS waterproof film is laminated on the electronic paper membrane, the surface of the internal PS waterproof film is coated with adhesive, and the internal PS waterproof film is laminated to the external PS waterproof film via the adhesive.

[0007] Preferably, the internal PS waterproof membrane is a smooth PS waterproof membrane.

[0008] Preferably, the adhesive is OCA optical glue.

[0009] Preferably, the external PS waterproof membrane is a matte PS waterproof membrane, and the thickness of the external PS waterproof membrane is 0.256±0.0128 mm.

[0010] Preferably, the thickness of the electronic paper TFT backplane is 0.5±0.05 mm.

[0011] Preferably, the thickness of the electronic paper film is 0.156±0.02 mm.

[0012] Preferably, the thickness of the internal PS waterproof membrane is 0.256±0.0128 mm.

[0013] Preferably, the thickness of the adhesive is 0.175 mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] An external matte PS waterproof film is used to replace the cover. The external matte PS waterproof film has no border and can maintain the viewing area of ​​the electronic paper display without reducing it. It can be fully laminated without leaving any gaps, thus reducing the overall thickness of the electronic price tag display. The matte PS waterproof film can achieve no scattering or reflection, is more eye-friendly, and can bring a better display experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3As shown, a new electronic price tag structure includes an electronic paper TFT backplane 1, an electronic paper membrane 2, an internal PS waterproof film 3, an adhesive 4, and an external PS waterproof film 5. The electronic paper TFT backplane 1 is laminated with the electronic paper membrane 2, and the internal PS waterproof film 3 is laminated with the electronic paper membrane 2. The surface of the internal PS waterproof film 3 is coated with adhesive 4, and the internal PS waterproof film 3 is laminated to the external PS waterproof film 5 through the adhesive 4.

[0022] In this embodiment, the internal PS waterproof membrane 3 is a smooth PS waterproof membrane.

[0023] In this embodiment, the adhesive 4 is OCA optical adhesive.

[0024] In this embodiment, the external PS waterproof membrane 5 is a matte PS waterproof membrane, and the thickness of the external PS waterproof membrane 5 is 0.256±0.0128 mm.

[0025] In this embodiment, the thickness of the electronic paper TFT backplane 1 is 0.5±0.05 mm.

[0026] In this embodiment, the thickness of the electronic paper film 2 is 0.156±0.02 mm.

[0027] In this embodiment, the thickness of the internal PS waterproof membrane 3 is 0.256±0.0128 mm.

[0028] In this embodiment, the thickness of the adhesive 4 is 0.175 mm.

[0029] Working principle: The external PS waterproof film 5 completely replaces the cover plate, and can ensure that the external PS waterproof film 5 and the electronic paper TFT backplane 1 are consistent in size and fully fitted. The external PS waterproof film 5 is fully transparent and borderless, and will not reduce the viewing area of ​​the electronic paper display.

[0030] like Figure 2As shown, the electronic paper TFT backplane 1 is used as a substrate and placed at the bottom of the electronic paper display. The electronic paper film 2 is attached to the electronic paper TFT backplane 1. After the electronic paper aluminum film is peeled off, it can be directly attached to the electronic paper TFT backplane 1. The internal PS waterproof film 3 needs to use a glossy PS waterproof film. The glossy PS waterproof film has the advantages of smooth surface, high transmittance, and no scattering. It provides a smooth surface for the subsequent attachment of the external PS waterproof film 5, so as to facilitate the subsequent attachment of the external PS waterproof film 5. After the internal PS waterproof film 3 is bonded, adhesive 4 needs to be applied on top of the internal PS waterproof film 3. Adhesive 4 uses OCA optical glue. OCA optical glue is colorless and transparent, has a light transmittance of more than 95%, good bonding strength, can be cured at room temperature or medium temperature, and has small curing shrinkage. Using OCA optical glue to bond the external PS waterproof film 5 not only ensures the adhesion of the electronic paper display, but also ensures the high transmittance of the electronic paper display. The external PS waterproof film 5 needs to use matte PS waterproof film. The matte PS waterproof film has an atomized surface and has an anti-glare function. The screen will not have strong reflections, affecting the line of sight and causing discomfort to customers.

[0031] like Figure 3 As shown in the figure, the new electronic price tag structure that uses a double-layer PS waterproof film instead of a cover plate can significantly reduce the overall thickness of the electronic price tag display screen. The thickness of the electronic paper TFT backplane 1 is 0.5±0.05mm, the thickness of the electronic paper membrane 2 is 0.156±0.02mm, the thickness of the internal PS waterproof film 3 is 0.256±0.0128mm, the thickness of the adhesive 4 is 0.175mm, and the thickness of the external PS waterproof film 5 is 0.256±0.0128mm. The total thickness of the entire electronic paper display screen is 1.4±0.10mm, which makes the electronic price tag lighter and thinner, saves a lot of space for the assembly of the electronic price tag, and provides more possibilities for subsequent practical application placement.

[0032] The circuits, electronic components and control modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.
