[0002] More and more wearable devices on the market, such as watches and wristbands, now have built-in NFC antennas for payment, electronic tickets, or data exchange and collection with smart media.

[0003] like Figure 1 The conventional design is shown below: from top to bottom, the following components are arranged: cover plate, OCA optical adhesive layer, film layer, OCA optical adhesive layer, LCD liquid crystal layer, and NFC antenna; one side of the LCD liquid crystal layer is connected to an outwardly extending FPC flexible circuit board; when manufacturing the conventional design, a protective foam layer with a thickness of 0.13 to 0.2 mm needs to be attached to the back of the display module to attach the NFC antenna to the display module.

[0004] Conventional designs typically incorporate an NFC antenna on the back of the display module, leading to a more complex manufacturing process, higher production costs, and a lack of alignment with consumer demand for thinner and lighter wearable products. Therefore, we need to develop a thinner and lighter solution to meet current market demands. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an integrated display module to solve the problem of excessive thickness in existing display modules.

[0006] The technical solution of this utility model is an integrated display module, including a cover plate, an OCA optical adhesive layer, and an LCD liquid crystal layer;

[0007] The display module consists of, from top to bottom, a cover plate, an OCA optical adhesive layer, a film layer, another OCA optical adhesive layer, and an LCD liquid crystal layer.

[0008] The LCD liquid crystal layer is located at the bottom of the display module; an OCA light-emitting adhesive layer is set above and below the film layer to be bonded and fixed to the LCD liquid crystal layer and the cover plate respectively;

[0009] The film layer is integrated with the NFC antenna to form an integrated functional layer, which reduces the overall thickness of the display module.

[0010] Preferably, one side of the LCD liquid crystal layer is connected to an outwardly extending FPC flexible circuit board.

[0011] Preferably, the wiring in the NFC antenna is integrated with the film layer.

[0012] Preferably, the wiring in the NFC antenna is integrated on the outer periphery of the film layer; the middle part of the film layer is transparent.

[0013] Preferably, a touch pattern or line can be provided on the transparent part in the middle of the film layer.

[0014] Preferably, ink areas are provided on both sides of the cover plate; the ink areas are used to cover the traces in the NFC antenna integrated on the film layer.

[0015] Preferably, the width of the ink area is greater than the width of the traces in the NFC antenna.

[0016] Preferably, black ink is used in the ink area.

[0017] Preferably, the NFC antenna uses conductive silver paste on the film layer to arrange the wiring.

[0018] Preferably, the wiring process is completed through the steps of exposure, development, stripping, screen printing silver paste / curing, and screen printing silver paste / curing.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] This invention integrates the NFC antenna routing scheme into the film. Patterns are created on the film according to the NFC antenna routing requirements. The specific process is: exposure-development-removal-silver paste screen printing / curing-silver paste screen printing / curing, thus completing the antenna circuit. Using film-based silver paste for the circuitry offers higher conductivity compared to traditional copper-based NFC circuits, and it can be applied to the same film layer as other circuitry (such as touch patterns), reducing the overall module thickness. This significantly simplifies the module structure, allowing for thinner products and lower costs. Attached Figure Description

[0028] The film layer 4 is integrated with the NFC antenna 1 to form an integrated functional layer, for reducing the overall thickness of the display module.

[0029] In the embodiment, one side of the LCD liquid crystal layer 2 is connected with the FPC flexible circuit board 6 extending outward.

[0030] As an optional embodiment, the wiring line in the NFC antenna 1 is integrated with the film layer 4, and the wiring line in the NFC antenna 1 is integrated on the outer periphery of the film layer 4; the middle part of the film layer 4 is a transparent body, and a touch control pattern or line can be arranged on the middle part of the transparent body of the film layer 4; for displaying a specific touch control pattern, and the line is used for connecting power supply for the touch control pattern.

Using the film silver paste to make the line has higher conductivity than the traditional NFC copper metal, and can be made on the same layer of film with other lines (such as a touch control pattern), thereby reducing the total thickness of the module. In this way, the module structure can be greatly simplified, and the product can be made thinner and lower in cost.
