Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screens, in particular to a display module with a UV color-changing protective film. Background Art
[0002] At present, most display modules will stick a process protection film before full bonding and curing to protect the conveyor belt from scratching the sample during the curing process. After the curing is completed, the process protection film will be torn off and the finished product black film will be affixed. The black background provided by the black film is conducive to observing the defects of the sample and preventing the defective products from leaking to the client. At the same time, display modules are often bonded by full bonding with solid optical adhesive (OCA). After bonding with solid OCA, UV irradiation is required to cure the OCA. However, in actual production, production line employees may miss the UV oven after baking the bonded products and directly transfer the bonded products to the next process. Uncured products are indistinguishable from cured products in appearance, and are easily flowed to clients and have quality problems. Utility Model Content

[0030] refer to Figure 1-4 , the embodiment of the utility model provides a display module with a UV color-changing protective film, comprising: a cover plate 100, a silk-screen ink layer 200 and a UV color-changing protective film 300 arranged in sequence from bottom to top;
[0031] The UV color-changing protective film 300 includes a transparent area 310 and a color-changing area 320;
[0032] The cover plate 100 includes a display area 110 and a non-display area 120;
[0033] The silk-screen ink layer 200 is disposed on the non-display area 120 , the transparent area 310 is disposed on the silk-screen ink layer 200 , and the color-changing area 320 is disposed on the display area 110 .
[0034] In the utility model, by setting a UV color-changing protective film, after being irradiated by UV ultraviolet light, the color-changing area will change, such as turning black, which is equivalent to adding a black background at the bottom of the cover plate, making it easy to observe defects (such as scratches) on the cover plate, thereby eliminating the cost of using traditional protective films and the steps of replacing them, and improving production efficiency; in addition, after the display module is cured in a UV furnace, the change of the UV color-changing protective film also makes it easy to intuitively distinguish whether the display module has been UV cured, thereby reducing the flow of uncured products to the client, ensuring the product yield, and avoiding usage accidents.
[0035] As a preferred embodiment of the present invention, please refer to Figure 1 , and further includes a touch film 400, which is disposed between the display area 110 of the cover plate 100 and the UV color-changing protective film 300. Thus, the display module has a touch function.
[0036] As a preferred embodiment of the present invention, please refer to Figure 1 The touch film 400 is externally connected to an FPC structure 410. The FPC structure 410 is used to connect to an external client, thereby realizing the touch function of the display module.
[0037] As a preferred embodiment of the present invention, the touch film 400 is bonded to the display area 110 of the cover plate 100 using optical adhesive. Therefore, the display module bonding piece needs to be cured in a UV oven, and the UV color-changing protective film will also change color after being cured in a UV oven, so that it is easy to visually distinguish whether the display module has been UV-cured, thereby reducing the flow of uncured products to the client, ensuring the product yield, and avoiding usage accidents.
[0038] As a preferred embodiment of the present invention, after the UV color-changing protective film 300 is irradiated with ultraviolet light, the transparent area 310 remains unchanged, and the color-changing area 320 changes from transparent to black. The above arrangement makes the color-changing area 320 corresponding to the display area 110 turn black, which can facilitate the inspection of the appearance defects of the cover plate in the display area, and the non-visual area of the silk-screen ink layer (non-display area) is transparent, which is convenient for QC appearance defects in the ink area.
[0039] As a preferred embodiment of the present invention, the four sides of the cover plate 100 are designed in a 2D or 3D arc shape. The above arrangement can reduce the collision and breakage of the side of the cover plate and improve the aesthetics.
[0040] As a preferred embodiment of the present invention, the cover plate 100 is made of AG glass, so that the display module has an anti-glare function.
[0041] As a preferred embodiment of the present invention, the cover plate 100 is coated with an AF anti-fingerprint film on the side away from the silk-screen ink layer 200, so that the display module has an anti-fingerprint function.
[0042] As a preferred embodiment of the present invention, please refer to Figure 5-6 The silk screen printing ink layer 200 includes a first ink layer 210 and a second ink layer 220 arranged sequentially from bottom to top.
[0043] As a preferred embodiment of the present invention, please refer to Figure 5-6 The first ink layer 210 includes a key hollow portion 211 , and the color of the first ink layer 210 is different from the color of the second ink layer 220 .
[0044] For example, the first ink layer 210 is black, which can make the appearance of the display module more integrated, and the second ink layer 220 is white, so that the white ink can be seen through the key hollow part 211, that is, the cover surface of the display module is a white key display, which is convenient for distinguishing the keys.
[0045] The beneficial effects achieved by the display device provided by the present invention refer to the beneficial effects in any embodiment of the present invention.
[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
