首先，将内膜片和外膜片30各自印刷成型后，把内膜片两侧表面的保护膜撕掉，把外膜片30两侧表面的保护膜撕掉。对内膜片和外膜片30进行表面灰尘除尘，例如，人工除尘和静电除尘相结合的方式进行除尘。First, after the inner diaphragm and the outer diaphragm 30 are printed and formed respectively, the protective films on both sides of the inner diaphragm are peeled off, and the protective films on both sides of the outer diaphragm 30 are peeled off. The surface dust of the inner diaphragm and the outer diaphragm 30 is removed, for example, by a combination of manual dust removal and electrostatic dust removal.

然后，把除尘后的内膜片放在模具的模腔一侧，并真空吸附固定；把除尘后的外膜片30放在模具的模腔另一侧，并真空吸附固定。例如，内膜片放在定膜的模腔内，外膜片30放在动模的模腔内；或者，内膜片放在动膜的模腔内，外膜片30放在定模的模腔内。Then, place the dust-removed inner diaphragm on one side of the mold cavity and vacuum-adsorb to fix it; place the dust-removed outer diaphragm 30 on the other side of the mold cavity and vacuum-adsorb to fix it. For example, the inner diaphragm is placed in the mold cavity of the fixed diaphragm, and the outer diaphragm 30 is placed in the mold cavity of the movable mold; or the inner diaphragm is placed in the mold cavity of the movable diaphragm, and the outer diaphragm 30 is placed in the mold cavity of the fixed mold. inside the mold cavity.

待树脂冷却后，开模，得到注塑成型产品。After the resin cools, the mold is opened to obtain an injection molded product.

需要说明的是，一些实施例中，注塑成型产品可以是最终的成品，即无需再采用其他工艺。It should be noted that in some embodiments, the injection molded product may be the final product, that is, no other process is required.

另一些实施例中，注塑成型产品为半成品，需要进一步进行处理，例如，采用紫外光照射注塑成型产品等。In other embodiments, the injection molded product is a semi-finished product that requires further processing, for example, the injection molded product is irradiated with ultraviolet light.

示例性地，请参阅图1、图3、图5、图6，膜片包括用于匀光的匀光层14，电路层12和图形层13均设置于匀光层14的外侧。显示面板100点亮时，光线从显示面板100的内侧向外侧的方向穿过显示面板100，光线先穿过匀光层14，后穿过电路层12和图形层13，需要说明的是，此处的电路层12和图形层13的顺序不限，例如，可以先穿过电路层12、后穿过图形层13，也可以先穿过图形层13，又穿过电路层12。光线在穿过匀光层14的过程中，匀光层14起到较好的匀光效果，使得显示面板100呈现的亮度较为均匀柔和，且用户不易看到显示面板背后的发光源。For example, please refer to FIGS. 1 , 3 , 5 and 6 . The film includes a uniform light layer 14 for uniform light. The circuit layer 12 and the graphic layer 13 are both disposed outside the uniform light layer 14 . When the display panel 100 is lit, light passes through the display panel 100 from the inside to the outside of the display panel 100. The light first passes through the uniform light layer 14, and then passes through the circuit layer 12 and the graphics layer 13. It should be noted that this The order of the circuit layer 12 and the graphic layer 13 is not limited. For example, the circuit layer 12 may be passed through first and then the graphic layer 13 may be passed, or the graphic layer 13 may be passed first and then the circuit layer 12 may be passed. When light passes through the light-diffusion layer 14 , the light-diffusion layer 14 has a better light-diffusion effect, making the brightness of the display panel 100 more uniform and soft, and making it difficult for users to see the light source behind the display panel.

需要说明的是，匀光层起到匀光的作用，匀光层采用的印刷材料不限。例如，一些实施例中，匀光层为扩散油墨层，也就是说，匀光层的印刷材料为油墨，油墨通过印刷的方式扩散印刷，需要说明的是，该扩散油墨层能够透光。It should be noted that the uniformity layer plays the role of uniformity, and the printing material used in the uniformity layer is not limited. For example, in some embodiments, the light uniformity layer is a diffusion ink layer, that is to say, the printing material of the light uniformity layer is ink, and the ink is diffusely printed by printing. It should be noted that the diffusion ink layer can transmit light.

匀光层14可以设置于基材层11的外表面(参照图5)，也可以设置于基材层11的内表面。The light uniformity layer 14 may be provided on the outer surface of the base material layer 11 (see FIG. 5 ), or may be provided on the inner surface of the base material layer 11 .

示例性地，请参阅图1、图3和图6，匀光层14设置于基材层11的内表面。For example, please refer to FIG. 1 , FIG. 3 and FIG. 6 , the light uniformity layer 14 is provided on the inner surface of the base material layer 11 .

匀光层14中的油墨具有粉状颗粒物，其与基材层11或者相邻的其他层之间的结合力相对较弱。需要说明的是，基材层11作为内膜片的载体，如果基材层11和注塑层20之间的结合力不够，则基材层11容易剥落，导致产品成为不合格品。The ink in the light uniformity layer 14 contains powdery particles, and its bonding force with the base material layer 11 or other adjacent layers is relatively weak. It should be noted that the base material layer 11 serves as the carrier of the inner diaphragm. If the bonding force between the base material layer 11 and the injection molding layer 20 is insufficient, the base material layer 11 will easily peel off, resulting in a defective product.

该实施例中，由于匀光层14设置在注塑层20的内表面，当内膜片结合在注塑层20上后，匀光层14的弱结合力不影响基材层11与注塑层20之间的结合力，基材层11和注塑层20之间具有较好的结合力，在显示面板100成型后进行环境测试等环节中，基材层11不易从注塑层20上剥离下来，能够保证显示面板100的可靠性。In this embodiment, since the light uniformity layer 14 is disposed on the inner surface of the injection molding layer 20, when the inner diaphragm is combined with the injection molding layer 20, the weak binding force of the light uniformity layer 14 does not affect the relationship between the base material layer 11 and the injection molding layer 20. There is a good bonding force between the base material layer 11 and the injection molding layer 20. During the environmental testing and other processes after the display panel 100 is formed, the base material layer 11 is not easily peeled off from the injection molding layer 20, which can ensure Reliability of the display panel 100 .

该实施例中，由于匀光层14设置在基材层11的内侧，即使匀光层14与基材层11之间的结合力仍然较弱，但是，由于基材层11作为结构载体，其本身不易从注塑层20上剥落，且匀光层14本身是一层薄薄的涂层，匀光层14本身没有像基材层11一样的片材，因此，匀光层14本身不会在基材层11上起翘、剥落。In this embodiment, since the light uniformity layer 14 is disposed inside the base material layer 11 , even though the bonding force between the light uniformity layer 14 and the base material layer 11 is still weak, since the base material layer 11 serves as a structural carrier, its It is not easy to peel off from the injection molding layer 20, and the light-diffusing layer 14 itself is a thin coating. The light-diffusing layer 14 itself does not have a sheet like the base material layer 11, so the light-diffusing layer 14 itself will not The base material layer 11 is lifted and peeled off.

示例性地，请参阅图1至图7，图形层13设置于电路层12的外表面。该实施例中，图形层13对电路层12起到遮挡作用，用户不易看到电路层12上的电路。For example, please refer to FIGS. 1 to 7 , the graphics layer 13 is disposed on the outer surface of the circuit layer 12 . In this embodiment, the graphics layer 13 blocks the circuit layer 12 , making it difficult for users to see the circuits on the circuit layer 12 .

需要说明的是，图形层13可以完全遮挡电路层12，或者，图形层13中的图形区域遮挡电路层12中的电子器件。It should be noted that the graphics layer 13 can completely block the circuit layer 12 , or the graphics area in the graphics layer 13 can block the electronic devices in the circuit layer 12 .

一些实施例中，图形层13设置于基材层11的外表面，电路层12设置于基材层11的内表面。也就是说，图形层13和电路层12位于基材层11的相对两侧的表面。In some embodiments, the graphic layer 13 is disposed on the outer surface of the base material layer 11 , and the circuit layer 12 is disposed on the inner surface of the base material layer 11 . That is to say, the graphic layer 13 and the circuit layer 12 are located on the surfaces of opposite sides of the base material layer 11 .

该实施例中，基材层11采用双面印刷的生产工艺，一方面，能够降低所有印刷层均集中在基材层11的同一侧面而出现的不良品率。此外，图形层13在电路层12的外侧，对电路层12起到较好的遮挡效果。In this embodiment, the base material layer 11 adopts a double-sided printing production process. On the one hand, it can reduce the defective product rate that occurs when all printing layers are concentrated on the same side of the base material layer 11 . In addition, the graphic layer 13 is outside the circuit layer 12 and has a better shielding effect on the circuit layer 12 .

相关技术中，各印刷层均布置在基材层11的外侧，由于逐层布置，由此，各印刷层出现的误差容易被累积放大，由此导致的产品不良率较高。In the related art, each printing layer is arranged outside the base material layer 11. Due to the layer-by-layer arrangement, errors occurring in each printing layer are easily accumulated and amplified, resulting in a high product defect rate.

该实施例中，基材层11采用双面印刷，在印刷层的总层数相同的情况下，双面印刷能够减少单侧的印刷层的层数，能够降低因单侧印刷层数过多而导致的不良率。In this embodiment, the base material layer 11 adopts double-sided printing. When the total number of printing layers is the same, double-sided printing can reduce the number of printing layers on one side and can reduce the risk of excessive printing layers on one side. resulting in defective rates.

一些实施例中，请参阅图3，图形层13设置于基材层11的外表面，电路层12设置于基材层11的内表面，且电路层12设置于匀光层14和基材层11之间。该实施例中，匀光层14不影响电路层12和基材层11之间的结合力，还能起到匀光的作用；此外，图形层13在基材层11的外表面，图形层13上的油墨能够更好地附着在注塑层20上，能够呈现出更加清晰的外观观感。In some embodiments, please refer to FIG. 3 , the graphic layer 13 is disposed on the outer surface of the base material layer 11 , the circuit layer 12 is disposed on the inner surface of the base material layer 11 , and the circuit layer 12 is disposed on the uniform light layer 14 and the base material layer. between 11. In this embodiment, the uniform light layer 14 does not affect the binding force between the circuit layer 12 and the base material layer 11, and can also play a role in uniform light; in addition, the graphic layer 13 is on the outer surface of the base material layer 11, and the graphic layer The ink on 13 can better adhere to the injection molding layer 20 and can present a clearer appearance.

另一些实施例中，请参阅图1和图2，图形层13和电路层12均设置于基材层11的外表面，且电路层12设置于图形层13和基材层11之间。In other embodiments, please refer to FIGS. 1 and 2 , the graphic layer 13 and the circuit layer 12 are both disposed on the outer surface of the base material layer 11 , and the circuit layer 12 is disposed between the graphic layer 13 and the base material layer 11 .

该实施例中，电路层12和图形层13均能够较好地附着在注塑层20上，再者，基材层11在电路层12的内侧，对电路层12也能起到较好的保护作用。In this embodiment, both the circuit layer 12 and the graphic layer 13 can be well adhered to the injection molding layer 20 . Furthermore, the base material layer 11 is inside the circuit layer 12 and can also better protect the circuit layer 12 effect.

一些实施例中，匀光层14设置于膜片的内侧最表层。In some embodiments, the light uniformity layer 14 is disposed on the innermost surface layer of the film.

其中，本申请实施例中，最表层指的是最表面的一层，最表层背离基材层11的一侧没有其他的印刷层。Among them, in the embodiment of the present application, the outermost layer refers to the outermost layer, and there is no other printing layer on the side of the outermost layer away from the base material layer 11 .

该实施例中，由于匀光层14起到匀光作用，且匀光层14不会存在用户或外部环境的刮擦，因此，无需在匀光层14的表面再刷一层。如此，在满足使用性能的前提下，还能够降低成本。In this embodiment, since the light evening layer 14 plays a light evening role, and the light evening layer 14 will not be scratched by the user or the external environment, there is no need to paint another layer on the surface of the light evening layer 14 . In this way, costs can be reduced while meeting performance requirements.

示例性地，请参阅图8和图12，膜片包括隔离片16，隔离片16设置于基材连接带15的外表面，并至少覆盖印刷于基材连接带15靠近基材层11一端的连接诶电路。Illustratively, please refer to FIGS. 8 and 12 . The diaphragm includes a separator 16 . The separator 16 is disposed on the outer surface of the base material connecting belt 15 and at least covers the labels printed on one end of the base material connecting belt 15 close to the base material layer 11 . Connect the circuit.

隔离片16起到保护电路的作用，防止在注塑过程中被注入的树脂材料烧毁。The isolation sheet 16 plays a role in protecting the circuit and preventing the injected resin material from burning during the injection molding process.

具体地，注塑过程中，将内膜片放置于模具的型腔中，基材连接带15靠近基材层11的一端位于型腔内，远离基材层11的另一端位于型腔外，位于型腔内的部位会与注入的树脂接触，因此，隔离片16至少需要覆盖基材连接带15位于型腔内的部位，以隔离电路和树脂材料，防止树脂材料在浇注过程中烧毁电路。Specifically, during the injection molding process, the inner diaphragm is placed in the cavity of the mold. One end of the base material connecting belt 15 close to the base material layer 11 is located in the mold cavity, and the other end away from the base material layer 11 is located outside the mold cavity. The parts inside the mold cavity will be in contact with the injected resin. Therefore, the isolation sheet 16 needs to cover at least the parts of the base material connecting tape 15 located in the mold cavity to isolate the circuit and the resin material and prevent the resin material from burning the circuit during the pouring process.

需要说明的是，基材连接带15位于型腔之外的部位，可以覆盖有隔离片16，也可以不用覆盖隔离片16。It should be noted that the portion of the base material connecting strip 15 located outside the mold cavity may be covered with the isolation sheet 16 or may not be covered with the isolation sheet 16 .
