[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] The utility model provides a transparent window screen, which can prevent users from directly seeing the light strip, while increasing the brightness of the central area of ​​the product, making the backlight consistency better and improving the subjective effect of the product.

[0029] Reference Figure 1 and Figure 2The embodiment of the utility model proposes a transparent window screen, comprising: an outer shell 11, comprising an inner cavity 111; the inner cavity 111 has a top surface and multiple wall surfaces, the wall surfaces include a screen surface and a lining surface, at least one of the wall surfaces is a screen surface, and the screen surface is transparent and visible; a backlight panel assembly, the backlight panel assembly is fixed to the top surface, the backlight panel assembly includes a light-emitting surface, the light-emitting surface faces the interior of the inner cavity 111, and the light-emitting surface emits light; a reflector, at least one of the reflectors is arranged on at least one of the lining surfaces, one side of the reflector is a reflective surface, and the reflective surface faces the interior of the inner cavity 111; wherein, there is an angle between the light-emitting surface and at least one of the reflective surfaces, and the light emitted by the light-emitting surface is reflected by the reflective surface and points to the central area of ​​the screen surface.

[0030] In this embodiment, the housing 11 is the frame of the entire transparent window screen, and is used to support and fix various components. Figure 1 and Figure 2 Inside the shell 11 is an inner cavity 111, and the inner cavity 111 has multiple wall surfaces, of which the front side is a transparent visible screen surface, and the screen surface enables the user to see the exhibits displayed in the transparent window screen. The other wall surfaces of the inner cavity 111 are invisible lining surfaces, the bottom is a bearing surface for bearing exhibits, and the top is a top surface, and the backlight panel assembly is installed on the top surface. The back reflective sheet 17 is arranged on the lining surface directly opposite the front screen surface, the ground side reflective sheet 18 is arranged on the bearing surface, and the left and right wall reflective sheets 19 are arranged on the left and right wall surfaces, and the reflective surfaces of all reflective sheets are facing the inside of the inner cavity 111. The reflective surfaces of all reflective sheets are to reflect light to improve the lighting efficiency and make the transparent window screen brighter.

[0031] Furthermore, the backlight panel assembly has a light-emitting surface, wherein the light-emitting surface faces the interior of the inner cavity 111 to provide light for the transparent window screen, and there is an angle between the light-emitting surface and the reflective surface of the back reflective sheet 17. The angle of reflection of the light emitted from the normal direction of the light-emitting surface after being reflected by the reflective surface is equal to the angle of the angle, and the reflection angle points to the central area of ​​the screen surface. In actual applications, the angle can be adjusted through customized design according to the different external dimensions and product requirements of the product and the different display requirements of the internal exhibits.

[0032] Through this embodiment, relying on the angle between the light-emitting surface of the backlight panel assembly arranged on the top of the transparent window screen and the reflective surface of at least one reflective member arranged on the lining surface, the light emitted through the light-emitting surface of the backlight panel assembly is reflected by the reflective surface and then directed to the central area of ​​the screen surface, and the light is finally projected to the central area of ​​the screen surface, thereby improving the brightness of the central area of ​​the product, avoiding the problem of unclear display when the external light intensity is slightly stronger, and improving the subjective effect of the product.

[0033] In one embodiment, the backlight panel assembly further includes: a backlight panel shell 12, the backlight panel shell 12 is fixed to the top surface, and the backlight panel shell 12 is provided with a mounting groove 122, the mounting groove 122 is recessed toward the top surface, and the notch of the mounting groove 122 faces away from the top surface. The mounting groove 122 is provided to accommodate the LED light board 13, the bottom surface of the recessed mounting groove 122 is a plane, and the opening of the groove is downward, so that the light can be directed to the inside of the inner cavity 111. In actual application, a fixing component for fixing the LED light board 13 will also be installed on the bottom surface of the mounting groove 122.

[0034] In one embodiment, the backlight panel assembly further includes: an LED light board 13, the LED light board 13 is fixedly mounted on the side of the mounting groove 122 facing away from the top surface, the LED light board 13 includes a lamp bead surface, the lamp bead surface faces away from the top surface, LED chips are mounted on the lamp bead surface, and the LED chips are arranged in an array. The LED light board 13 is a component that provides illumination for the entire transparent window screen, and the upper side thereof is a lamp bead surface equipped with LED chips, and is arranged in an array, for example, using LED chips of the order of 100 μm. This arrangement structure can make the luminous intensity of the LED light board 13 stronger, the light source distribution more uniform, and no dark areas appear, thereby improving the taste and lighting effect of the transparent window screen.

[0035] In one embodiment, the LED lamp board 13 further includes a heat dissipation surface, which is disposed opposite to the lamp bead surface, and the heat dissipation surface is upwardly attached to a side of the mounting groove 122 that is opposite to the top surface.

[0036] During the light-emitting operation of the LED lamp board 13 , the heat generated needs to be conducted to the backlight board shell 12 by the heat dissipation surface for further heat dissipation.

[0037] In one embodiment, the backlight assembly further includes an optical film 14, which is disposed at the notch of the mounting groove 122 and is located on the side of the lamp bead surface away from the top surface. The light emitted from the lamp bead on the LED chip on the LED light board 13 is narrowed in angle after passing through the optical film 14, and the scattering is reduced after being emitted from the optical film 14, and the directivity becomes stronger. At the same time, the optical film 14 also prevents the user from directly seeing the lamp bead, and will not cause glare due to direct viewing.

[0038] In one embodiment, referring to Figure 3There are two card slots 123 on both sides of the mounting slot 122 of the backlight shell 12. The two card slots 123 are arranged symmetrically with the normal line of the bottom surface of the mounting slot 122 at the center point as the axis, and the two edges of the optical film 14 are inserted into the above two card slots 123. The fit between the optical film 14 and the two card slots 123 is a clearance fit. When the two edges of the optical film 14 are inserted into the two card slots 123, the optical film 14 can be smoothly unfolded, so that the optical film 14 is not easy to shake. Furthermore, the optical film 14 made by the symmetrical card slots 123 relies on its own rigidity and clearance fit, so that the optical film 14 has a certain flatness and is parallel to the lamp bead surface of the backlight shell 12. If the flatness of the optical film 14 is insufficient due to its own gravity or case fit, it will cause the light to be scattered after being emitted from the optical film 14, and the directivity is poor, and the preset effect of the optical film 14 cannot be achieved.

[0039] In one embodiment, referring to Figure 3 The backlight panel assembly is mainly composed of a backlight panel shell 12, an LED light panel 13 and an optical film 14. The backlight panel shell 12 is a rectangular flat profile made of aluminum, the LED light panel 13 is a rectangular plate body used to fit the backlight panel shell 12, and the optical film 14 is a rectangular sheet body used to fit the backlight panel shell 12. The two sides of the LED light panel 13 can be divided into a lamp bead surface and a heat dissipation surface. The heat dissipation surface of the LED light panel 13 is upwardly attached to the bottom surface of the mounting groove 122 of the backlight panel shell 12, and the heat generated by the lamp beads on the lamp bead surface when working is conducted to the backlight panel shell 12.

[0040] In one embodiment, the backlight panel shell 12 is also provided with a grid-shaped heat sink 121, and the heat sink 121 is arranged on the side of the backlight panel shell 12 facing the top surface. The heat sink 121 and the backlight panel shell 12 are integrally formed, and the material is the same as aluminum. The heat sink 121 provides heat dissipation for the backlight panel assembly. Specifically, when the heat generated by the lamp beads on the lamp bead surface is conducted to the backlight panel shell 12 when working, the heat is dissipated by air cooling through the heat sink 121. Furthermore, there is a certain gap between the backlight panel assembly and the top surface of the shell. Furthermore, the fitting gap between the heat dissipation surface of the LED light panel 13 and the bottom surface of the mounting groove 122 of the backlight panel shell 12 is also filled with a filler with enhanced thermal conductivity to further enhance the heat dissipation capability.

[0041] In one embodiment, referring to Figure 3The backlight panel shell 12 further includes a supporting wing 124, which is arranged on the outer peripheral side of the backlight panel shell 12. The supporting wing 124 includes a first contact surface 1241 and a second contact surface 1242, wherein the first contact surface 1241 is located above the supporting wing 124, and the second contact surface 1242 is located below the supporting wing 124. The first contact surface 1241 is fixedly attached to the top surface to provide support for the entire backlight panel assembly. There is an angle between the second contact surface 1242 and the top surface. Specifically, when processing the backlight panel shell 12, the first contact surface 1241 is processed so that there is an angle between the first contact surface 1241 and the second contact surface 1242. The second contact surface 1242 is parallel to the light-emitting surface of the backlight panel assembly. When the first contact surface 1241 is in contact with the top surface, there is an angle between the light-emitting surface and the reflective surface of the back reflective sheet 17. The angle can be adjusted through customized design according to the product's external dimensions and product requirements and the different display requirements of internal exhibits. In actual use, the second contact surface 1242 and the observable part of the top surface will also be in contact with a reflective sheet to further improve the efficiency of light utilization.

[0042] In one embodiment, referring to Figure 1 and Figure 3 When the backlight panel shell 12 is processed, its mounting groove 122 is customized, so that when the light-emitting panel assembly is fixed on the top surface of the horizontal inner cavity 111, there is an angle between the bottom surface of the mounting groove 122 and the reflective surface of the back reflective sheet 17. Accordingly, the angle is installed specifically so that a part of the light emitted from the backlight panel assembly will be reflected by the back reflective sheet 17 and illuminate the center of the screen surface, thereby improving the brightness of the central area of ​​the product and avoiding the problem of unclear display when the external light intensity is slightly strong.

[0043] In one embodiment, a plurality of lifting devices, such as nut lifting devices, are arranged between the supporting wings 124 of the backlight panel shell 12 and the top surface of the inner cavity 111. By adjusting the lifting devices, the angle between the light-emitting surface of the backlight panel assembly and the reflective surface of the back reflective sheet 17 is changed, so that the lighting effect of the central area of ​​the product can be changed for different exhibits in the same transparent window screen product, so that the transparent window screen in the embodiment can be used more widely and diversely.

[0044] In one embodiment, referring to Figure 1 The transparent visible screen surface of the transparent window screen is covered with a liquid crystal panel 15, and the outer side of the liquid crystal panel 15 is also covered with a touch screen 16. The user can interact with the touch screen 16 to change the display content of the liquid crystal panel 15 and the luminous brightness of the backlight assembly according to a preset program.

[0045] In one embodiment, the inner cavity 111 has three transparent visible screen surfaces and a transparent window screen with an inwardly recessed invisible curved wall surface, so that the user can observe the product from multiple angles. The reflective element on the curved wall surface reflects the light emitted by the top backlight panel assembly along the curved surface to all visible surfaces, so that the light on each observation surface is uniform.

[0046] In one embodiment, the front of the inner cavity 111 of the transparent window screen is a transparent visible screen surface, the wall surface facing the screen surface is an invisible wall surface, and the left and right sides are mirror walls. Through the mutual reflection of the mirror walls on both sides, the transparent window screen can give users a stronger sense of spatial impact.

[0047] In one embodiment, the bearing surface and the top surface of the inner cavity 111 of the transparent window screen are provided with a backlight panel assembly, and a transparent plate is arranged between the backlight panel assembly on the bearing surface and the exhibit to bear the weight of the exhibit. By arranging the light sources up and down in this way, the shadows cast by the unidirectional light source on the exhibit are eliminated, thereby enhancing the display capability of the transparent window screen for the exhibits.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
