[0002] In recent years, electronic equipment has been widely used because of its powerful function and excellent user experience. In order to improve the overall visual effect and design aesthetic feeling, many electronic products adopt NCVM film layer film for coating on the display screen cover plate, so that the device in the off state has better concealment and improves the overall integration effect. For example, streaming media rearview mirror, industrial control panel and the like widely adopt this configuration.

[0040] It should be noted that the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0041] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0042] Embodiment one

[0043] Please refer to Figures 2-4 A display module for eliminating ghosting phenomenon, comprising a cover plate 100, the cover plate 100 comprises cover plate glass 110, ink layer 120, NCVM film layer 130 and AGARAF film layer 140, the NCVM film layer 130 is arranged on the bottom surface of the cover plate glass 110, the AGARAF film layer 140 is arranged on the top surface of the cover plate glass 110, and the ink layer 120 is arranged on the bottom surface of the NCVM film layer 130;

[0044] OCA optical glue 200, the OCA optical glue 200 is arranged on the bottom surface of the ink layer 120;

[0045] Display screen assembly 300, the display screen assembly 300 is arranged on the bottom surface of the OCA optical glue 200.

[0046] Through the above structural design, the OCA optical adhesive 200 can firmly bond the display screen assembly 300 and the cover plate 100 together, preventing the display screen assembly 300 from being damaged or deformed due to external factors during use. At the same time, the cover plate 100 can effectively prevent the surface of the display screen assembly 300 from being contaminated or scratched. The AGARAF film layer 140 is made on the upper surface of the cover plate glass 110. The AGARAF film layer 140 can be directly disposed on the surface of the cover plate glass 110 by coating or sputtering. On the other hand, the AGARAF film layer 140 can also be attached to the TAC or PET substrate. After the AGARAF film layer 140 is made on the upper surface of the glass, when the light is emitted from the glass to the air layer, due to the existence of the AR film, the reflected light is reduced (i.e. the reflectivity is reduced). Due to the existence of AG, even a small amount of light is reflected, but the reflected light is scattered by the AG film layer and cannot form a clear image. Therefore, even if the observer is at a large angle, he cannot see the existence of ghosting. By making the AGARAF film layer 140 on the upper surface of the glass cover plate 100, the optical transmittance is improved and the ghosting problem is eliminated. When the light is emitted from the glass to the air layer, the AR film layer reduces the reflected light, and the AG film layer scatters a small amount of reflected light, so that it cannot form a clear image. Therefore, even if the observer is at a large angle, he cannot see the existence of ghosting, thereby realizing good transmission effect and clear observation experience.

[0047] Specifically, the ink layer 120 is arranged around the bottom edge of the NCVM film layer 130.

[0048] Through the above structural design, the ink on the mobile phone cover plate 100 can play a role in protecting the screen and preventing the screen from being scratched and worn.

[0049] Specifically, the length and width distances of the AGARAF film layer 140, the cover plate glass 110 and the NCVM film layer 130 are equal.

[0050] Through the above structural design, the length and width distances of the AGARAF film layer 140, the cover plate glass 110 and the NCVM film layer 130 are equal, which is aligned and beautiful.

[0051] Specifically, the AGARAF film layer 140 is disposed on the top surface of the cover plate glass 110 by coating or sputtering.

[0052] Through the above structural design, the optical transmittance is improved by making the AGARAF film layer 140 on the upper surface of the cover plate glass 110, and the ghosting problem is eliminated. When the light exits from the glass to the air layer, the AR film layer reduces the reflected light, and the AG film layer scatters a small amount of reflected light, so that it cannot form a clear image. Therefore, even if the observer is at a large angle, the existence of ghosting cannot be seen, thereby realizing good transmission effect and clear observation experience.

[0053] Specifically, the AGARAF film layer 140 includes a substrate layer, and the material of the substrate layer is TAC or PET.

[0054] Through the above structural design, the substrate is made of transparent resin type material TAC or PET, which makes the film more tough and durable, and also maintains excellent light transmittance.

[0055] Example two

[0056] The display module provided in Example 1 is further optimized, and specifically, as shown in Figures 2-4 The display screen assembly 300 includes the display module 400 arranged on the bottom surface of the OCA optical adhesive 200, and the backlight module 500 arranged on the bottom surface of the display module 400.

[0057] Through the above structural design, the OCA optical adhesive 200 can firmly bond the display screen assembly 300 and the cover plate 100 together, preventing the display screen assembly 300 from being damaged or deformed due to external factors during use. At the same time, the cover plate 100 can effectively prevent the surface of the display screen assembly 300 from being contaminated or scratched.

[0058] Example three

[0059] The display module provided in Example 1 or 2 is further optimized, and specifically, as shown in Figures 2-4 The display module 400 includes, from top to bottom, an upper polarizer 410, an upper glass sheet 420, a lower glass sheet 430, and a lower polarizer 440.

[0060] Through the above structural design, the display module 400 realizes light polarization control through the clever combination of the upper polarizer 410, the upper glass sheet 420, the lower glass sheet 430, and the lower polarizer 440, thereby presenting a clear and bright image. The working principle is as follows: the light first passes through the upper polarizer 410, allowing only vertically polarized light to pass through, and then enters the lower glass sheet 430 after being reflected by the upper glass sheet 420. When passing through the lower polarizer 440, only a part of the light whose polarization direction is consistent with the direction of the lower polarizer 440 will pass through, because the polarization direction of the lower polarizer 440 is perpendicular to that of the upper polarizer 410. This part of the light finally reaches the observer's eyes, forming a visible image.

[0061] Specifically, the backlight module 500 comprises an iron frame 510 and an optical module 520 arranged in the iron frame 510. The optical module 520 comprises a reflecting sheet 530 arranged on the iron frame 510, a light guide plate 540 arranged on the top of the reflecting sheet 530, a diffusion film 550 arranged on the top of the light guide plate 540, and a light enhancement assembly 560 arranged on the top of the diffusion film 550.

[0062] Through the above structural design, the reflecting sheet 530 reflects the light upward by using the mirror reflection characteristic, the light guided to the diffusion film 550 by the light guide plate 540, and the diffusion film 550 diffuses the light evenly, and finally the light enhancement assembly 560 further enhances the diffused light, so that the light emitting effect is brighter and more uniform.

[0063] Specifically, the light enhancement assembly 560 comprises an upper light enhancement film 561 and a lower light enhancement film 562, and the upper light enhancement film 561 is arranged on the upper surface of the lower light enhancement film 562.

[0064] Through the above structural design, when the light irradiates on the upper light enhancement film 561, a part of the light is reflected back to the lower light enhancement film 562, and the lower light enhancement film 562 transmits the reflected light, so that multiple reflection and redirection of the light transmission barrier are formed, and finally most of the light can pass through the optical element, thereby improving the light transmittance of the whole optical element.

[0065] The use process of the display module for removing ghosting phenomenon provided by the utility model is as follows:

[0066] By manufacturing the AGARAF film layer 140 on the upper surface of the cover glass 110 to improve the optical transmittance and eliminate the ghosting problem, when the light is emitted from the glass to the air layer, the AR film layer reduces the reflected light, and the AG film layer scatters a small amount of reflected light, so that it cannot form a clear image, therefore, even if the observer is at a large angle, the existence of ghosting cannot be seen, thereby realizing good transmission effect and clear observation experience.
