[0002] VA liquid crystal (Vertical Alignment liquid crystal) is the abbreviation of vertically aligned liquid crystal. Compared with TN liquid crystal, VA liquid crystal has higher contrast and wider viewing angle. It is the mainstream technology used in today's large-screen LCD TVs. VA LCD screens are mainly used for display of TV screens, smart phones, handheld game consoles and other devices.

[0003] China Patent Publication No.: CN 209858908 U discloses the "Full Viewing Angle VA Liquid Crystal Display Screen Structure", which sets a surface display component and a bottom display component. In actual application, since the width of the segmented electrode is 5:1 to the width of the surface groove adjacent to the segmented electrode, and the width of the common electrode is 5:1 to the width of the bottom groove adjacent to the common electrode, the transmittance and contrast performance of the full viewing angle VA liquid crystal display screen structure are kept at a high value, and the black spots can be greatly reduced, making the display reliability of the full viewing angle VA liquid crystal display screen structure more reliable, and effectively avoiding the problem of unreasonable groove design in the existing full viewing angle VA liquid crystal screen, which leads to low transmittance and black spots.

[0004] However, when VA LCD screens are used as mobile phone screens or handheld game console screens, users often apply films on the surface to protect privacy, thus achieving privacy protection through anti-peep films.

[0005] It can be seen that there is an urgent need for a full-viewing angle VA liquid crystal display structure to achieve an anti-peeping function and reduce the trouble of users applying a film. Utility Model Content

[0008] Preferably, the PE protective film, PET layer, hardened layer and surface PE protective film are all made of transparent materials, and the projected areas of the PE protective film, PET layer, hardened layer and surface PE protective film are all equal to the VA liquid crystal screen body.

[0009] Preferably, the anti-peeping structures are trapezoidal in shape, and are evenly distributed with gaps between them.

[0010] Preferably, the angle between the two trapezoidal surfaces of the privacy protection structure is 25°, and the privacy protection structure layer strips are spread over the top of the PET layer.

[0011] Preferably, the hardened layer comprises an AG hardened layer, grooves are provided on both sides of the AG hardened layer, and light strips are installed inside the grooves.

[0012] Preferably, the outer surface of the light strip is level with the outer surface of the AG hardened layer, and the interior of the light strip is filled with soft light beads.

[0013] Preferably, a flat cable is provided on the side of the light strip, one end of the flat cable is connected to the soft light bead, and the other end is connected to the inside of the VA liquid crystal screen body and is controlled separately.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model respectively arranges a PE protective film, a PET layer, an anti-peeping structure, a hardening layer and a surface PE protective film on the top of the VA LCD screen body. When the VA LCD screen body is in use, the light of the VA LCD screen body will be shielded by the anti-peeping structure, so that the two sides of the VA LCD screen body cannot directly see the content displayed on the VA LCD screen body, thereby achieving an anti-peeping effect.

[0016] Second, the utility model installs an AG hardened layer above the anti-peeping structure and has functional light strips on both sides of the AG hardened layer. When anti-peeping is not needed, the light strips emit light, so that the anti-peeping structure reduces the light-shielding property under the effect of the light, so that the content displayed on the VA LCD screen body can be seen from the side of the VA LCD screen body, thereby achieving the effect of turning the anti-peeping function on and off.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Through the above technical scheme, a PE protective film 2, a PET layer 3, an anti-peeping structure 4, a hardening layer 5 and a surface PE protective film 6 are respectively arranged on the top of the VA LCD screen body 1. When the VA LCD screen body 1 is in use, the light of the VA LCD screen body 1 will be shielded by the anti-peeping structure 4, so that the two sides of the VA LCD screen body 1 cannot directly see the content displayed on the VA LCD screen body 1, thereby achieving an anti-peeping effect.

[0025] Specifically, the PE protective film 2 , the PET layer 3 , the hardened layer 5 and the surface PE protective film 6 are all made of transparent materials, and the projection areas of the PE protective film 2 , the PET layer 3 , the hardened layer 5 and the surface PE protective film 6 are all equal to the VA liquid crystal screen body 1 .

[0026] Through the above technical scheme, the sizes of the PE protective film 2, the PET layer 3, the hardened layer 5 and the surface PE protective film 6 are set so that the PE protective film 2, the PET layer 3, the hardened layer 5 and the surface PE protective film 6 can completely cover the surface of the VA liquid crystal screen body 1 to avoid incomplete coverage and light transmittance. During use, the PE protective film 2, the PET layer 3, the hardened layer 5 and the surface PE protective film 6 can protect the outer surface of the VA liquid crystal screen body 1 to avoid scratches on the surface of the VA liquid crystal screen body 1 and cause unclear display.

[0027] Specifically, the anti-peeping structures 4 are trapezoidal, and the anti-peeping structures 4 are evenly distributed with gaps between them.

[0028] Through the above technical solution, the anti-peeping structure 4 is set to a trapezoid, thereby forming a shading structure with an angle, so as to prevent the image displayed by the VA LCD screen body 1 from spreading from the side, thereby playing an anti-peeping role, and the gap between the anti-peeping structures 4 is used for light transmission, so that the user in front of the VA LCD screen body 1 can see the content displayed by the VA LCD screen body 1.

[0029] Specifically, the angle between the two trapezoidal surfaces of the anti-peeping structure 4 is 25°, and the 4 layers of strips of the anti-peeping structure are spread all over the top of the PET layer 3 .

[0030] Through the above technical solution, the angle between the anti-peeping structures 4 is set to 25°, so that the image can be seen from the front of the VA LCD screen body 1, while the VA LCD screen body 1 is blocked from the side outside the 25° angle, and only the dark side can be seen, so as to achieve the effect of clear observation from the front and complete anti-peeping from the side.

[0031] Embodiment 2

[0032] See also Figure 1 and 4 A full-viewing angle VA liquid crystal display structure comprises a VA liquid crystal screen body 1, the top of the VA liquid crystal screen body 1 is covered with a PE protective film 2, the top of the PE protective film 2 is covered with a PET layer 3, an anti-peeping structure 4 is arranged above the PET layer 3, the top of the anti-peeping structure 4 is covered with a hardening layer 5, and the top of the hardening layer 5 is covered with a surface PE protective film 6;

[0033] The hardening layer 5 includes an AG hardening layer 501, and grooves are provided on both sides of the AG hardening layer 501. A light strip 502 is installed inside the groove. The outer surface of the light strip 502 is level with the outer surface of the AG hardening layer 501. The inside of the light strip 502 is a soft light bead. Therefore, when the light strip 502 is turned on, the eyes will not be hurt or the screen content will not be unclear due to excessive light intensity. A flat cable 503 is provided on the side of the light strip 502. One end of the flat cable 503 is connected to the soft light bead, and the other end is connected to the inside of the VA LCD screen body 1 and is controlled separately, so that the light strip 502 can be controlled to switch on and off separately to be turned on according to actual needs.

[0034] Through the above technical solution, an AG hardened layer 501 is installed above the anti-peeping structure 4, and a functional light bar 502 is installed on both sides of the AG hardened layer 501. When anti-peeping is not needed, light is emitted through the light bar 502, so that the anti-peeping structure 4 reduces the light-shielding property under the effect of light and increases the brightness of the screen, so that the side of the VA LCD screen body 1 can see the content displayed on the VA LCD screen body 1, thereby achieving the effect of turning the anti-peeping function on and off.

[0035] When in use, by respectively arranging the PE protective film 2, the PET layer 3, the anti-peeping structure 4, the hardening layer 5 and the surface PE protective film 6 on the top of the VA liquid crystal screen body 1, when the VA liquid crystal screen body 1 is in use, the light of the VA liquid crystal screen body 1 will be shielded by the anti-peeping structure 4, so that the two sides of the VA liquid crystal screen body 1 cannot directly see the content displayed on the VA liquid crystal screen body 1, thereby achieving the anti-peeping effect;

[0036] By installing an AG hardened layer 501 above the anti-peeping structure 4 and placing functional light strips 502 on both sides of the AG hardened layer 501, when anti-peeping is not needed, light is emitted through the light strips 502, so that the anti-peeping structure 4 reduces the light-shielding property under the effect of light, so that the side of the VA LCD screen body 1 can see the content displayed on the VA LCD screen body 1, thereby achieving the effect of turning the anti-peeping function on and off.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
