[0002] Reflective film is an optical film used in TFT-LCD display modules to improve the luminous efficiency of the entire backlight system. By applying reflective film to the display modules of small-sized electronic devices such as mobile phones, digital cameras, and tablets, and utilizing optical principles such as reflection and total reflection, and by cooperating with the light guide plate, the light passing through the light guide plate and the light reflected back by the light enhancement film can be directed toward the front of the LCD screen again, thereby increasing the brightness of the display module and effectively improving the display effect of the display module while ensuring the compact structure of the display module of the electronic device.

[0003] The reflective film in the existing display module is usually connected to the light guide plate by gluing or bonding the reflective layer of the reflective film. In practical applications, although the display brightness of the display module is improved, the external light with a high concentration will be over-concentrated after being mirror-reflected at the reflective film. These lights will form undesirable phenomena such as light spots on the surface of the display screen, resulting in uneven brightness of the display module and poor display effect.

[0004] Therefore, it is necessary to make improvements to the above problems in order to change the current situation. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a method for processing a reflective film, comprising the following steps:

[0047] Step S100, providing a reflective layer 200 and a rolling mold 2;

[0048] Step S200, forming the reflective layer 200, coating the UV structural adhesive 120 on the reflective layer 200, and rolling the UV structural adhesive 120 through a rolling mold 2;

[0049] Step S300, UV curing the reflective layer 200, UV curing the rolled reflective layer 200 to form a diffuse reflective layer 200 on the reflective layer 200; wherein the diffuse reflective layer 200 includes a plurality of reflective portions 110, wherein at least two reflective portions 110 on the reflective layer 200 have different heights.

[0050] When the reflective film 10 is prepared by the processing method of this embodiment, a diffuse reflection layer 100 is set on the side of the reflective layer 200 away from the substrate layer 300, so that the light transmitted toward the reflective film 10 can be diffusely reflected at the diffuse reflection layer 100, and the light transmitted toward the side of the light guide plate 20 is in a diffuse reflection state. Compared with the mirror reflection form in the existing display module, the problem of light concentration can be effectively improved, and the problem of uneven brightness can be improved while improving the display brightness.

[0051] When testing the reflective film 10 manufactured by the processing method of this embodiment, the bonding state between the reflective layer 200 and the light guide plate 20 can be determined by lighting an external backlight source and evacuating the reflective film 10 .

[0052] Specifically, step S300 includes the following steps:

[0053] A rear pressure roller 3 is provided and arranged on one side of the rolling mold 2, driving the reflective layer 200 coated with the UV structural adhesive 120 to pass between the rolling mold 2 and the rear pressure roller 3, and the rear pressure roller 3 abuts the reflective layer 200 against the rolling mold 2; by cooperating with the rear pressure roller 3 and the rolling mold 2, the thickness of the reflective film 10, that is, the molding height of the diffuse reflection layer 100, can be controlled by adjusting the gap between the two; Figure 2 As shown, in this embodiment, along the processing flow of the reflective film 10, the rear pressure roller 3 is arranged downstream of the rolling mold 2. When the reflective film 10 is conveyed between the rolling mold 2 and the rear pressure roller 3, the rear pressure roller 3 can press the reflective film 10 so that the reflective layer 200 can be tightly attached to the rolling mold 2 to prepare a diffuse reflection layer 100 having a plurality of reflection parts 110 on the surface of the reflective layer 200.

[0054] Subsequently, the UV lamp 5 is used to irradiate the roll-formed reflective layer 200 to cure the UV structural adhesive 120 to form the diffuse reflective layer 200. After the rear pressure roller 3 extrude the reflective film 10, the UV lamp 5 is used to irradiate the reflective film 10 to cure the UV structural adhesive 120, thereby forming a complete structure of the reflective part 110 and improving the processing efficiency.

[0055] In one embodiment, step S100 includes the following steps:

[0056] A reflective layer 200 and a base layer 300 are provided, and the reflective layer 200 and the base layer 300 are bonded and fixed to each other by an adhesive 400 .

[0057] In this embodiment, the reflective layer 200 and the substrate layer 300 can be rolled up and transported by respective rollers. When the reflective layer 200 and the substrate layer 300 are transported to the rolling mold 2, the adhesive 400 can be applied between the two to bond and fix them.

[0058] Further, step S200 includes the following steps:

[0059] A front pressure roller 4 is provided and arranged upstream of the rolling mold 2; with this arrangement, when the reflective film 10 is conveyed between the rolling mold 2 and the front pressure roller 4, the thickness of the composite reflective layer 200 and the substrate layer 300 can be controlled by setting the distance between the front pressure roller 4 and the rolling mold 2.

[0060] The reflective layer 200 is molded, UV structural adhesive 120 is coated on the reflective layer 200 and the reflective layer 200 is driven through between the rolling mold 2 and the front pressure roller 4 , and the front pressure roller 4 abuts the reflective layer 200 against the rolling mold 2 .

[0061] When the processing method of this embodiment is used to process the reflective layer 200, the front pressure roller 4 cooperates with the rolling mold 2, and the front pressure roller 4 can not only provide pressure for the composite between the reflective layer 200 and the substrate layer 300, but also provide pressure for the UV structural adhesive 120 on the surface of the reflective layer 200 rolled by the rolling mold 2; Figure 2 As shown, when the front pressure roller 4 cooperates with the rear pressure roller 3 and the rolling mold 2, the rear pressure roller 3 and the front pressure roller 4 are arranged on the side of the reflective film 10 away from the rolling mold 2, and because the rear pressure roller 3 and the front pressure roller 4 are arranged at an interval, the reflective film 10 can be tightened on the rolling mold 2 to ensure the molding accuracy of the UV structural adhesive 120 into the reflective part 110.

[0062] In one embodiment, the adhesive 400 is UV glue, and the UV glue between the reflective layer 200 and the substrate layer 300 is cured and bonded by a UV lamp 5 .

[0063] It should be noted that the reflective film in the existing display module is processed by coating the adhesive layer with a micro-concave roller, and then the substrate is compounded with PET. Since the structural layer needs to be formed on the back of the PET base film, a further process is required for the forming. In addition, since the reflective film in the prior art is processed by heat curing, after the film is formed and rolled as a whole, it needs to be put into a drying room for curing so that the adhesive can be cured by heating.

[0064] Compared with the existing reflective film processing method, the processing method of this embodiment includes at least the following advantages: first, the reflective layer 200, the substrate layer 300, and the molded diffuse reflective layer 100 are all made of UV curing glue, which can be cured and formed by irradiation with a UV lamp 5. The overall processing flow is free of solvents and VOC emissions, and the environmental friendliness of the processing is improved. At the same time, by simultaneously molding the diffuse reflective layer 100, the composite reflective layer 200, and the substrate layer 300 in one process, the process can be saved to improve the overall processing efficiency of the reflective film 10. In addition, since the UV structural glue 120 and the adhesive 400 are both UV cured, they can be quickly (instantly) cured after irradiation with the UV lamp 5, and the processing efficiency and processing quality are guaranteed. At the same time, when the prepared reflective film 10 is rolled up, it does not need to be cured again, and the overall processing efficiency is also improved, and the processing quality of the reflective film 10 is guaranteed.

[0065] Specifically, see Figure 2As shown, the processing method also includes a winding process, which specifically includes the following steps:

[0066] A winding roller 6 is provided and arranged downstream of the rolling mold 2 , and the reflective film 10 formed with the diffuse reflection layer 100 is rolled up and collected by the winding roller 6 .

[0067] It can be understood that in this embodiment, after the reflective film 10 is wound on the winding roller 6, the reflective film 10 and the winding roller 6 can be packaged as a whole for transportation and storage. The molding strength of the reflective film 10 can be ensured without additional heating and curing, the processing difficulty is improved, and the product quality of the reflective film 10 is also improved.

[0068] See also Figures 3 to 8 As shown, an embodiment of the present invention further provides a reflective film 10, which can be prepared by the processing method in any of the above embodiments. Specifically, the reflective film 10 includes a diffuse reflection layer 100, a reflective layer 200 and a substrate layer 300. The reflective layer 200 is stacked on one side of the substrate layer 300 and bonded and fixed to the substrate layer 300; the diffuse reflection layer 100 is formed on the side of the reflective layer 200 away from the substrate layer 300, and the diffuse reflection layer 100 is used to contact the external light guide plate 20 and reflect the light transmitted by the light guide plate 20 in a direction away from the reflective layer 200; the diffuse reflection layer 100 includes a plurality of reflective portions 110, wherein the contact areas of at least two of the reflective portions 110 with the light guide plate 20 are different.

[0069] In the reflective film 10 of the present embodiment, by arranging the diffuse reflection layer 100 on the side of the reflective layer 200 away from the substrate layer 300, the light transmitted toward the reflective film 10 can be diffusely reflected at the diffuse reflection layer 100, and the light transmitted toward the side of the light guide plate 20 is in a diffuse reflection state. Compared with the mirror reflection form in the existing display module, the problem of light concentration can be effectively improved, and the problem of uneven brightness can be improved while improving the display brightness. In a preferred embodiment, the reflective layer 200 is a silver-plated film to ensure that the light passing through the diffuse reflection layer 100 and / or entering the reflective layer 200 can be reflected by the reflective layer of the silver-plated film so that it is transmitted in a direction away from the substrate layer 300.

[0070] It should be noted that in the existing display module, the reflective film and the light guide plate are directly bonded, that is, the two are in surface contact. With this arrangement, when the light passes through the contact interface between the two, the transmission direction will not change (only the form of the contact interface is considered, and the refraction caused by the material difference is not considered). This results in the light changing the transmission direction only through reflection after being reflected by the reflective film. After the light is reflected, the light will remain in a concentrated state. After the light is projected onto the surface of the display screen, a light spot will be formed on its surface, causing the display screen to have an uneven brightness problem.

[0071] Specifically, in the present embodiment, by providing a plurality of reflective portions 110 on the reflective layer 200, compared with the existing display module, the contact mode between the reflective layer 200 and the light guide plate 20 can be changed from surface contact to point contact. This is because the structure and arrangement position of the reflective portion 110 on the reflective layer 200 are randomly arranged, and the light guide plate 20 and the reflective layer 200 are connected by a plurality of reflective portions 110 with different heights and shapes. When external light is transmitted to the diffuse reflection layer 100, the reflective portion 110 in the diffuse reflection layer 100 can diffusely reflect the light so that it continues to be transmitted evenly along the light path, so that the light is evenly projected onto the surface of the display screen. The phenomenon of uneven light can be avoided while improving the brightness of the display screen, and the use effect is good.

[0072] See also Figures 4 to 8 As shown, in some embodiments, the height difference L between the two reflective portions 110 is 1-3 μm.

[0073] By setting a height difference between at least two of the reflection parts 110, the diffuse reflection layer 100 and the light guide plate 20 can have multiple contact points, and the reflection layer 200 and the light guide plate 20 can be connected in a point contact manner under the premise of ensuring the firmness of the connection between the reflection layer 200 and the light guide plate 20, so as to achieve the diffuse reflection effect of the diffuse reflection layer 100. Figure 3 As shown, the distance D between the light guide plate 20 and the reflective layer 200 is 5-50 μm.

[0074] Specifically, the base material layer 300 is any one of a PET film, a white film, a black film, an aluminum-plated film, and a silver-plated film.

[0075] It is understandable that when using the reflective film 10 of this embodiment, the substrate layer 300 of the corresponding material can be selected according to the actual design requirements of the reflective film 10, and no sole limitation is made here.

[0076] In a preferred embodiment, the diffuse reflection layer 100 is a UV adhesive curing structure.

[0077] When preparing the diffuse reflection layer 100 in the reflective film 10 of this embodiment, UV structural adhesive 120 can be coated on the reflective layer 200, and then the UV structural adhesive 120 on the reflective layer 200 is rolled by a rolling mold 2 to form the diffuse reflection layer 100, and then the molded UV structural adhesive 120 is irradiated by a UV lamp 5 to form a reflective portion 110 on the diffuse reflection layer 100.

[0078] See also Figure 4 and Figure 5As shown, in the first embodiment, the reflective portion 110 is a spherical structure, and the diameter of the spherical structure is 1-30 μm. The performance parameters of the five specific examples are as follows:

[0079]

[0080] See also Figure 6 As shown, in the second embodiment, one end of the reflective portion 110 is attached to the reflective layer 200, the other end of the reflective portion 110 is a spherical structure, and the spacing between two adjacent reflective portions 110 is 5-50 μm. The performance parameters of the specific five examples are as follows:

[0081]

[0082] See also Figure 7 As shown, in the third embodiment, the reflective portion 110 is an ellipsoid structure, and the particle size of the ellipsoid structure is 5-50 μm. The performance parameters of the five specific examples are as follows:

[0083]

[0084] See also Figure 8 As shown, in the fourth embodiment, the side of the reflective portion 110 away from the reflective layer 200 is a concave structure, and the diameter 2R of the concave structure is 20-200 μm. The performance parameters of the five specific examples are as follows:

[0085]

[0086] See also Figure 3 As shown, the present invention also provides a display module 1, which includes a reflective film 10, a light guide plate 20 and a light source 30, the light source 30 is arranged on one side in the plane direction of the light guide plate 20, and the light source 30 is used to emit light toward the light guide plate 20; the reflective film 10 is attached to the light emitting side of the light guide plate 20, the light guide plate 20 is parallel to the reflective film 10 and attached, the light guide plate 20 can transmit the light emitted by the light source 30 toward the side of the light guide plate 20 to the reflective film 10, so as to realize the diffuse reflection function of the diffuse reflection layer 100.

[0087] It can be understood that in the display module 1 of this embodiment, by setting the reflective film 10 in any one of the above embodiments in cooperation with the light guide plate 20, the diffuse reflection layer 100 can diffusely reflect the light transmitted by the light guide plate 20. Compared with the display module in the prior art, the reflection uniformity of the light can be improved, thereby improving the problem of uneven brightness of the display module 1.

[0088] The present invention further provides an electronic device, which comprises the display module 1 in the above embodiment.

[0089] Specifically, electronic devices include but are not limited to mobile phones, digital cameras, and tablet computers. It can be understood that by applying the display module 1 in the above embodiment in the present electronic device, the miniaturization design requirements of the electronic device (small-size electronic device) can be achieved first. At the same time, by arranging a reflective film 10 with a diffuse reflection layer 100 inside the display module 1, the light passing through the diffuse reflection layer 100 can be diffusely reflected and transmitted, thereby avoiding the problem of uneven brightness of the display surface of the display module 1 due to light concentration. On the premise of improving the display brightness of the display module in the electronic device, the display effect of the electronic device can be effectively improved.
