[0033] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] refer to Figures 1 to 5 The dynamic anti-peeping side-entry backlight source provided by the utility model includes a die-casting 1, the top of the die-casting 1 is provided with an opening 11, and a receiving cavity 12 is formed below the opening 11. The receiving cavity 12 is stacked with an anti-peeping viewing angle display component 2 and a full-viewing angle display component 3 from bottom to top, and the anti-peeping viewing angle display component 2 and the full-viewing angle display component 3 are electrically connected to the control end respectively. The anti-peeping viewing angle display component 2 and the full-viewing angle display component 3 are stacked in the receiving cavity 12, so that the display of the anti-peeping viewing angle and the full-viewing angle are both located in the same display area, and the switching of different viewing angles can be realized through the control of the control end. On the one hand, it reduces the occupied space of the backlight source, reduces the production materials of the backlight source, and saves costs; on the other hand, switching between different viewing angles in the same display area improves the convenience of use, which is conducive to enhancing the user experience.

[0037] Further, the anti-peeping viewing angle display assembly 2 includes a first light guide plate 21, a first light strip 22, an optical film 23, an anti-peeping film 24 and a first frame 25. In some embodiments, the first light strip 22 is attached to the inner wall of the accommodating cavity 12 by means of a thermally conductive adhesive, and the first light strip 22 is located at one of the side edges of the first light guide plate 21. The optical film 23, the anti-peeping film 24 and the first frame 25 are located above the first light guide plate 21 in sequence from bottom to top. In some embodiments, a fixing adhesive may be affixed between the optical film 23 and the anti-peeping film 24, which is beneficial to maintaining the fixed position between the optical film 23 and the anti-peeping film 24, and is beneficial to maintaining a stable display. The optical film 23 is affixed to the inner wall of the accommodating cavity 12 by means of a fixing adhesive, which plays a fixing and limiting role. A fixing adhesive is affixed around the bottom of the first frame 25, and the first frame 25 can be fixed to the inner wall of the accommodating cavity 12.

[0038] Furthermore, the full-view display assembly 3 includes a second light guide plate 31, a second light strip 32, and a second frame 33. The second light guide plate 31 is connected to the first frame 25, and the second light strip 32 is connected to the accommodating cavity 12. In some embodiments, the second light strip 32 is attached to the inner wall of the accommodating cavity 12 by heat-conductive adhesive, and the second light strip 32 is located at one side of the second light guide plate 31. The second frame 33 covers the opening 11 and is located above the second light guide plate 31. In some embodiments, foam adhesive is attached between the second frame 33 and the second light guide plate 31, which can effectively prevent the second light guide plate 31 from being scratched by the second frame 33, affecting the normal use of the second light guide plate 31, and at the same time, the second frame 33 can be firmly connected to the second light guide plate 31. Since the area on the top of the second light guide plate 31 that is not covered by the second frame 33 is in a bare state, a protective film can be attached to the top of the second light guide plate 31 to protect the second light guide plate 31.

[0039] In some embodiments, a power connection portion is provided at one end of the first light strip 22 and the second light strip 32.

Anti-scratch glue is also provided between the power connection portion and the outer wall of the accommodating cavity 12, which, on the one hand, plays a fixing role, and on the other hand, can prevent the power connection portion from being scratched and affecting the connection.

[0040] Furthermore, the second light guide plate 31 is a transparent light guide plate. Since the second light guide plate 31 is located above the anti-peeping viewing angle display component 2, and the transparent light guide plate has good light transmittance, the use of the transparent light guide plate can reduce the light blocking of the anti-peeping viewing angle, reduce the brightness loss of the anti-peeping viewing angle, and ensure the normal display of the anti-peeping viewing angle.

A reflective strip 34 is attached between the bottom of the second light guide plate 31 and the first frame 25. Both the reflective bottom film 26 and the reflective strip 34 can enhance the reflection of light, and can respectively increase the brightness of the first light guide plate 21 and the second light guide plate 31, reduce brightness loss, and enhance the display effect.

[0042] As a further optimization, a first reflective side film 27 is attached between the side of the first light guide plate 21 and the accommodating cavity 12, and a second reflective side film 35 is attached between the side of the second light guide plate 31 and the accommodating cavity 12. The first reflective side film 27 and the second reflective side film 35 can respectively enhance the light reflection around the first light guide plate 21 and the second light guide plate 31, reduce the loss of light source, prevent the appearance of dark areas and other poor optical taste problems around, increase the display brightness, and improve the optical effect around the visible area.

[0043] As a further optimization, the first light strip 22 and the second light strip 32 are respectively installed on two opposite inner side walls of the accommodating cavity 12. The first light strip 22 and the second light strip 32 are arranged on different inner side walls of the accommodating cavity 12, so that the heat generated by the first light strip 22 and the second light strip 32 can be avoided from being concentrated on the same inner side wall, which is more conducive to heat dissipation, so as to ensure the normal and stable operation of the backlight source.
