[0023] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.
[0024] like Figure 1 and Figure 2 As shown, the film of the embodiment of the present disclosure includes a protective layer 1, a barrier layer 2 and a bottom layer 4 stacked in sequence, the protective layer 1 is arranged away from the screen body relative to the barrier layer 2, the barrier layer 2 is used to block external infrared light, the bottom layer 4 is connected to the barrier layer 2, and the bottom layer 4 is located on the side of the barrier layer 2 away from the protective layer 1.
[0025] It should be noted that the barrier layer 2 can block external infrared light, but can ensure the passage of visible light. The barrier layer 2 has a barrier rate of 80% to 90% for infrared red light, thereby reducing the impact of infrared light on the screen.
[0026] Specifically, Figure 1 and Figure 2 As shown, the protective layer 1 is located on the upper end of the barrier layer 2. In other words, the external light first passes through the protective layer 1 before reaching the barrier layer 2.
[0027] The membrane of the embodiment of the present disclosure can effectively reduce the absorption of infrared radiation energy by providing the barrier layer 2, thereby achieving a radiation cooling effect, which can reduce the heat generated by electronic equipment when exposed to sunlight and improve the use stability of the electronic equipment.
[0028] In some embodiments, the barrier layer 2 has a first avoidance hole 21 , which penetrates the barrier layer 2 along the thickness direction of the barrier layer 2 , and the position of the first avoidance hole 21 corresponds to the position of the optical distance sense under the screen.
[0029] The first avoidance hole 21 penetrates the barrier layer 2 in the up-down direction, the position of the first avoidance hole 21 corresponds to the position of the optical distance sensor under the screen, and the shape of the first avoidance hole 21 is the same as the shape of the optical distance sensor under the screen, the size of the first avoidance hole 21 is equal to the size of the optical distance sensor under the screen, or the size of the first avoidance hole 21 is slightly larger than the size of the optical distance sensor under the screen.
[0030] The diaphragm of the disclosed embodiment, by opening a first avoidance hole 21 on the barrier layer 2, and the position of the first avoidance hole 21 corresponds to the position line of the light distance sensor under the screen, so that the external infrared light can reach the light distance sensor under the screen, reducing or avoiding the blocking of the external infrared light at the light distance sensor under the screen by the barrier layer 2, thereby reducing or avoiding the influence of the diaphragm on the light distance sensor under the screen. In some embodiments, the barrier layer 2 has a second avoidance hole 22, and the second avoidance hole 22 penetrates the barrier layer 2 along the thickness direction of the barrier layer 2, and the position of the second avoidance hole 22 corresponds to the position of the button under the screen.
[0031] Specifically, Figure 2 As shown, the second avoidance hole 22 penetrates the barrier layer 2 in the up and down directions. The second avoidance hole 22 is located on the right side of the barrier layer 2, and the first avoidance hole 21 is located on the left side of the barrier layer 2. The position of the second avoidance hole 22 corresponds to the position of the under-screen button. By opening the second avoidance hole 22 on the barrier layer 2, the accuracy of the under-screen button operation is improved.
[0032] In some embodiments, the membrane further includes an oleophobic layer 3 , which is in contact with the protective layer 1 , and is located on a side of the protective layer 1 away from the barrier layer 2 .
[0033] It should be noted that the oleophobic layer 3 allows external light to pass through.
[0034] Specifically, Figure 1 As shown, the oleophobic layer 3 is located on the upper end of the protective layer 1. In other words, the oleophobic layer 3 is located on the outermost layer of the entire membrane. The oleophobic layer 3 can reduce or avoid fingerprints and scratches on the membrane.
[0035] In some embodiments, the film further includes a bottom layer 4 , which is connected to the barrier layer 2 , and is located on a side of the barrier layer 2 away from the protective layer 1 , and / or the protective layer 1 is a glass protective layer 1 .
[0036] It should be noted that the bottom layer 4 is a transparent plate, that is, the bottom layer 4 allows external light to pass through.
[0037] Specifically, Figure 1 As shown, the bottom layer 4 is located at the lower end of the barrier layer 2. In other words, the bottom layer 4 is located at the innermost side of the entire film. By providing the bottom layer 4, the structural strength of the film can be improved, and the protective effect of the film on the screen body can be improved.
[0038] In some embodiments, the film further comprises an adhesive layer 5, and the adhesive layer 5 is located between the bottom layer 4 and the barrier layer 2. By providing the adhesive layer 5, the barrier layer 2 is prevented from falling off, and the connection stability between the barrier layer 2 and the bottom layer 4 can be improved.
[0039] In some embodiments, the barrier layer 2 has a third avoidance hole 23 , and the third avoidance hole 23 penetrates the oleophobic layer 3 , the protective layer 1 , the barrier layer 2 , the adhesive layer 5 and the bottom layer 4 along the thickness direction of the barrier layer 2 .
[0040] Specifically, Figure 1 As shown, the oleophobic layer 3, the protective layer 1, the barrier layer 2, the adhesive layer 5 and the bottom layer 4 are stacked in sequence from top to bottom to form a membrane.
[0041] It should be noted that the third avoidance hole 23 corresponds to the position of the image component on the electronic device. For example, the image component can be a camera, and the position of the third avoidance hole 23 corresponds to the position of the camera. The third avoidance hole 23 not only penetrates the barrier layer 2 in the up and down directions, but also penetrates the entire diaphragm in the up and down directions, thereby preventing the diaphragm from changing the light propagation path and improving the camera effect.
[0042] In some embodiments, the first avoidance hole 21 and the third avoidance hole 23 are located on the same side of the barrier layer 2 .
[0043] Specifically, Figure 1 As shown, the first avoidance hole 21 and the third avoidance hole 23 are both located on the left side of the barrier layer 2, and the first avoidance hole 21 and the second avoidance hole 22 are arranged at intervals in the front-to-back direction.
[0044] Optionally, the projection area of the first avoidance hole 21 on the barrier layer 2 is larger than the projection area of the third avoidance hole 23 on the barrier layer 2. This ensures that external infrared light passes through the film, and reduces the infrared light blocking of the film at the optical distance sensing position under the screen.
