Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display device and electronic device. Background Technology

[0002] With the development of display technology, aerial imaging technology has emerged. Aerial imaging technology refers to projecting the image from a display panel into the air to achieve medium-free aerial imaging display. This technology is widely used in fields such as medicine, advertising, media, and automobiles. Aerial imaging technology mainly uses an equivalent negative refractive plate lens (DCT-plate) to reconverge diverging light rays in the air on the normal side of the plate lens through the principle of light field reconstruction, thereby forming a real image that requires a medium to support it, thus achieving aerial imaging. However, existing aerial imaging equipment has been found to be quite thick, resulting in a large space occupation.

[0003] Therefore, existing aerial imaging equipment suffers from the technical problem of excessive thickness. Utility Model Content

[0004] This utility model provides a display device and an electronic device to solve the technical problem of excessive thickness in existing aerial imaging devices.

[0005] To achieve the above objectives, according to a first aspect of the present invention, a display device is provided, the display device comprising:

[0006] Display panel;

[0007] A dimming structure is disposed on the light emission path of the display panel;

[0008] A flat plate lens is disposed on the side of the dimming structure away from the display panel, and the flat plate lens is disposed on the light output path of the dimming structure;

[0009] Wherein, the plane where the display panel is located and the plane where the flat lens is located form a first angle, the first angle being less than 45 degrees.

[0010] According to a second aspect of the present invention, an electronic device is provided, which includes a display device as described in any of the above embodiments.

[0011] This utility model provides a display device and an electronic device. The display device sets a dimming structure on the light-emitting path of the display panel and places a flat lens on the light-emitting path of the dimming structure, so that the first angle formed between the plane where the display panel is located and the plane where the flat lens is located is less than 45 degrees. This reduces the vertical space occupied by the display panel and the flat lens, thereby reducing the thickness of the display device. Furthermore, the angle of the light emitted from the display panel can be adjusted by the dimming structure, so that the light adjusted by the dimming structure can form a clear display image after exiting the flat lens, thus realizing the normal display of the display device.

[0012] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] To illustrate the principle behind the technical problems in the embodiments of this utility model, some comparative display devices are provided. It should be understood that these comparative display devices are not considered prior art in the embodiments of this utility model. Figure 1 As shown, the working principle of the negative refractive flat lens 112 lies in its internal micro-array structure, which can periodically change the light path to produce negative refraction, achieving light focusing without the need for a curved surface, such as... Figure 1 As shown, the light emitted by the light source 111 converges to an axisymmetric position about the cross-section of the negative refractive plate lens 112 after passing through the negative refractive plate lens 112, forming a 1:1 image 113, which is visible to the human eye 114.

[0023] Based on the working principle of the negative refractive flat plate lens 112, some contrast display devices achieve aerial display by setting the negative refractive flat plate lens 112, such as Figure 2 As shown, the contrast display device includes a cavity housing 121, a display screen 122 fixed inside the cavity housing 121, and a negative refractive plate lens 112 at the opening of the cavity housing 121. The display screen 122 and the negative refractive plate lens 112 form an angle α0, which is typically 45 degrees. When the contrast display device displays, the light emitted from the display screen 122 passes through the negative refractive plate lens 112 to form an aerial image 123 for the user to view. Figure 2 As can be seen, since the display screen 122 and the negative refractive plate lens 112 are at a certain angle, the display screen 122 and the negative refractive plate lens 112 need to occupy a certain vertical space, resulting in a large thickness H0 of the contrast display device. Therefore, the existing aerial imaging equipment has the technical problem of large thickness.

[0024] This utility model provides a display device and an electronic device to address the aforementioned technical problems.

Figure 4 This is a second schematic diagram of a display device provided in an embodiment of the present utility model. Figure 5 This is a third schematic diagram of a display device provided in an embodiment of the present utility model. Figure 6This is a fourth schematic diagram of the display device provided in an embodiment of the present utility model.

[0026] like Figures 3 to 6 As shown, this utility model embodiment provides a display device 2, which includes a display panel 21, a dimming structure 22 and a flat lens 23. The dimming structure 22 is disposed on the light-emitting path of the display panel 21, and the flat lens 23 is disposed on the side of the dimming structure 22 away from the display panel 21, and the flat lens 23 is disposed on the light-emitting path of the dimming structure 22.

[0027] Specifically, a first angle b2 is formed between the plane where the display panel 21 is located and the plane where the flat lens 23 is located, and the first angle b2 is less than 45 degrees.

[0028] This utility model embodiment provides a display device 2. The display device 2 sets a dimming structure 22 on the light-emitting path of the display panel 21 and sets a flat lens 23 on the light-emitting path of the dimming structure 22. The first angle formed between the plane where the display panel 21 is located and the plane where the flat lens 23 is located is less than 45 degrees. This reduces the longitudinal space occupied by the display panel 21 and the flat lens 23, thereby reducing the thickness of the display device. Furthermore, the angle of the light emitted from the display panel can be adjusted by the dimming structure 22, so that the light adjusted by the dimming structure 22 can form a clear display image after exiting the flat lens, thus realizing the normal display of the display device.

[0029] Specifically, when the display panel emits light, the light 26 emitted by the display panel 21 passes through the dimming structure 22 and the flat lens 23 to form a display image 24. The third angle b1 between the plane where the display image 24 is located and the plane where the flat lens 23 is located is greater than the first angle b2 between the plane where the display panel 21 is located and the plane where the flat lens 23 is located.

[0030] This utility model embodiment provides a display device 2. The display device 2 sets a dimming structure 22 on the light-emitting path of the display panel 21 and sets a flat lens 23 on the light-emitting path of the dimming structure 22. The third angle between the plane where the display image 24 is located and the plane where the flat lens 23 is located is greater than the first angle between the plane where the display panel 21 is located and the plane where the flat lens 23 is located. This makes the light emitted from the display panel 21 have a larger angle after exiting the flat lens 23, resulting in a better display effect. Furthermore, since the first angle between the plane where the display panel 21 is located and the plane where the flat lens 23 is located is reduced, the longitudinal space occupied by the display panel 21 and the flat lens 23 can be reduced, thereby reducing the thickness of the display device.

[0031] Specifically, compared to directly reducing the first angle between the plane of the display panel 21 and the plane of the flat lens 23, which would lead to display problems such as blurring of the displayed image 24, this embodiment of the invention uses a dimming structure 22 to adjust the light. By reducing the first angle between the plane of the display panel 21 and the plane of the flat lens 23, the light emitted from the display panel 21 can still present a clear image after passing through the flat lens 23, resulting in a better display effect. Furthermore, it can be understood that reducing the first angle between the plane of the display panel 21 and the plane of the flat lens 23 can reduce the thickness of the display device.

[0032] Specifically, by setting up a dimming structure 22, the light is adjusted. By reducing the first angle between the plane where the display panel 21 is located and the plane where the flat lens 23 is located, the third angle between the plane where the display image 24 is formed after the light emitted from the display panel exits the flat lens and the plane where the flat lens 23 is located can meet the optimal angle range. For example, when the display image 24 is displayed clearly, the third angle between the plane where the display image 24 is located and the plane where the flat lens 23 is located needs to be in the range of 30 degrees to 45 degrees. In this embodiment of the present invention, even when the first angle is less than 30 degrees, the third angle can still be in the range of 30 degrees to 45 degrees.

[0033] Specifically, the display panel 21 can be one of a liquid crystal display panel, an OLED (Organic Light-Emitting Diode) display panel, or a micro light-emitting diode display panel.

[0034] Specifically, the flat plate lens 23 can be a negative refractive flat plate lens.

[0035] In some embodiments, such as Figure 4 , Figure 5 As shown, the dimming structure 22 includes a lens 221, which diverges or converges the light emitted from the display panel 21. By including the lens 221 in the dimming structure 22, which diverges or converges the light emitted from the display panel 21, the light emitted from the display panel 21 is altered, resulting in a better display effect for the displayed image 24. Furthermore, the lens 221 can adjust the size of the displayed image 24.

[0036] Specifically, when setting lens 221, it can diverge the light emitted from display panel 21, making the displayed image 24 formed after the light emitted from display panel 21 passes through lens 221 and flat lens 23 larger. Alternatively, lens 221 can converge the light emitted from display panel 21, making the displayed image 24 formed after the light emitted from display panel 21 passes through lens 221 and flat lens 23 smaller, which can improve the display light intensity and display effect to a certain extent.

[0037] Specifically, the area of ​​the lens can be greater than or equal to the area of ​​the display panel, so that all the light emitted from the display panel can pass through the lens.

[0038] In some embodiments, such as Figure 4 As shown, the lens 221 includes a convex lens 221a, which protrudes towards the side of the flat lens 23. By including a convex lens in the lens 221, and making the convex lens 221a protrude towards the side of the flat lens 23, the light emitted from the display panel 21 is converged by the convex lens 221a when passing through the lens 221, which can increase the display light intensity to a certain extent and improve the display effect of the displayed image. Furthermore, the convex lens 221a can change the angle of the light emitted from the display panel, resulting in a better display effect for the displayed image 24.

[0039] Specifically, the area of ​​a convex lens can be greater than or equal to the area of ​​the display panel, so that all light emitted from the display panel can pass through the convex lens.

[0040] Specifically, when the lens is a convex lens, the area of ​​the flat lens can be reduced because the lens converges the light, thereby reducing the size of the display device. Specifically, the area of ​​the flat lens can be less than or equal to the area of ​​the display panel, but this embodiment of the invention is not limited to this; the area of ​​the flat lens can be larger than the area of ​​the display panel.

[0041] In some embodiments, such as Figure 5 As shown, lens 221 includes a concave lens 221b, which is concave on the side facing the flat plate lens 23. By including the concave lens 221b in lens 221, and making the concave lens 221b concave on the side facing the flat plate lens 23, the light emitted from the display panel 21 is diverged by the concave lens 221b when passing through lens 221, thus magnifying the image displayed on the display panel 21 after passing through lens 221 and the flat plate lens 23. Furthermore, the concave lens 221b can change the angle of the light emitted from the display panel, resulting in a better display effect for the displayed image 24.

[0042] Specifically, the area of ​​a concave lens can be greater than or equal to the area of ​​the display panel, so that all light emitted from the display panel can pass through the concave lens.

[0043] Specifically, when the lens is a concave lens, the area of ​​the flat lens can be increased because the concave lens diverges the light, making the area of ​​the flat lens larger than the area of ​​the display panel.

[0044] Specifically, the area of ​​the flat lens can be greater than or equal to 1.2 times the area of ​​the display panel.

[0045] In some embodiments, such as Figures 3 to 6 As shown, the display device 2 also includes a housing 25. An opening 25a is provided on one side of the housing 25. The display panel 21 is disposed within the housing 25, the dimming structure 22 is disposed within the housing 25, and the flat lens 23 is disposed at the opening of the housing 25. By providing the housing 25, the display panel 21 and the dimming structure 22 are disposed within the housing 25. The opening 25a on one side of the housing 25 and the flat lens 23 at the opening of the housing 25 allow light emitted from the display panel 21 to be diffused through the flat lens 23, preventing light leakage. Furthermore, the housing 25 houses the display panel 21, the dimming structure 22, and the flat lens 23, facilitating the use and portability of the display device 2.

[0046] Specifically, in Figures 3 to 6 In this case, since the flat lens 23 is disposed in the opening 25a of the housing 25, therefore, Figures 3 to 6 While the opening 25a is not visible, it is understandable that the flat lens 23 is positioned at the same location as the opening 25a.

[0047] Specifically, the side walls of the housing 25 can be opaque, or the inner side of the side walls of the housing 25 can be coated with a dark or light coating so that the light emitted by the display panel 21 will only scatter from the side with the flat lens 23, thus avoiding light leakage.

[0048] Specifically, the display panel 21 can be fixed to the housing 25, specifically by means of fasteners, such as screws, fittings, etc.

[0049] Specifically, the dimming structure 22 can be fixed to the housing 25, and can be fixed to the housing 25 by means of fasteners, such as screws, fittings, etc.

[0050] Specifically, the flat lens 23 can be fixed to the housing 25, and can be fixed to the housing 25 by means of fasteners, such as screws, fittings, etc.

[0051] Specifically, the above embodiment is illustrated by taking an opening on one side of the housing 25 and a flat lens 23 disposed at the opening of the housing 25 as an example. However, the embodiments of this utility model are not limited to this. The flat lens 23 can be disposed inside the housing 25, or it can be fixed to the housing 25. Alternatively, the flat lens 23 can be disposed outside the housing 25. For example, one side of the housing 25 can be designed to be light-transmitting, while the other sidewalls can be designed to be opaque, and the flat lens 23 can be disposed on the light-transmitting side of the housing 25.

[0052] In some embodiments, such as Figure 6 As shown, the housing 25 and the flat lens 23 form a sealed space, and the housing 25 is filled with inert gas 27. By filling the housing 25 with inert gas, the surfaces of the various structures within the housing 25 are kept clean and dry, thereby improving the performance and lifespan of the display device.

[0053] Specifically, by filling the housing 25 with inert gas 27, which replaces the humid air, the display panel 21 will not come into contact with water or oxygen, thus preventing water and oxygen from invading the display panel 21 and causing damage, thereby improving the yield and lifespan of the display panel. Furthermore, moisture will not adhere to the surfaces of the display panel, dimming structure, and flat lens, preventing moisture from affecting the angle of light and causing blurring of the displayed image, thereby improving the display effect of the display device.

[0054] Specifically, the casing 25 can be filled with nitrogen.

[0055] In some embodiments, such as Figures 3 to 6 As shown, there is a gap between the dimming structure 22 and the display panel 21. The gap between the dimming structure 22 and the display panel 21 is between one-third and one-half of the gap between the display panel 21 and the flat lens 23. By making the gap between the dimming structure 22 and the display panel 21 between one-third and one-half of the gap between the display panel 21 and the flat lens 23, the dimming structure 22 can adjust the angle of the light emitted from the display panel 21, so that the light emitted from the display panel 21 has a larger angle after exiting the flat lens 23, resulting in a better display effect.

[0056] Specifically, the distance between the center point of the display panel and the center point of the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21; or the minimum distance between the display panel and the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21; or the maximum distance between the display panel and the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21; the distance between the light-emitting surface of the display panel and the light-incident surface of the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21, specifically, the distance between the center point of the light-emitting surface of the display panel and the center point of the light-incident surface of the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21; or the distance between the light-emitting surface of the display panel and the light-emitting surface of the dimming structure can be used as the distance between the dimming structure 22 and the display panel 21. The spacing can be such that the distance between the center point of the light-emitting surface of the display panel and the center point of the light-emitting surface of the dimming structure is used as the spacing between the dimming structure 22 and the display panel 21; or the distance between the backlight surface of the display panel and the light-emitting surface of the dimming structure can be used as the spacing between the dimming structure 22 and the display panel 21, specifically the distance between the center point of the backlight surface of the display panel and the center point of the light-emitting surface of the dimming structure is used as the spacing between the dimming structure 22 and the display panel 21; or the distance between the backlight surface of the display panel and the light-incident surface of the dimming structure can be used as the spacing between the dimming structure 22 and the display panel 21, specifically the distance between the center point of the backlight surface of the display panel and the center point of the light-incident surface of the dimming structure is used as the spacing between the dimming structure 22 and the display panel 21.

[0057] Specifically, the distance between the center point of the display panel and the center point of the flat lens can be used as the distance between the display panel 21 and the flat lens 23; or the minimum distance between the display panel and the flat lens 23 can be used as the distance between the display panel 21 and the flat lens 23; or the maximum distance between the display panel 21 and the flat lens 23 can be used as the distance between the display panel 21 and the flat lens 23; or the distance between the center point of the light-emitting surface of the display panel 21 and the flat lens 23 can be used as the distance between the display panel 21 and the flat lens 23; or the distance between the center point of the backlight surface of the display panel 21 and the flat lens 23 can be used as the distance between the display panel 21 and the flat lens 23; or the distance between the light-emitting surface of the display panel and the light-incident surface of the flat lens 23 can be used as the distance between the display panel 21 and the flat lens 23. Specifically, the distance between the center point of the light-emitting surface of the display panel and the flat lens 23, or the distance between the center points of the light-incident surface of the flat lens 23, can be used as the distance between the display panel 21 and the flat lens 23. The distance between the display panel 21 and the flat lens 23 can be: The distance between the light-emitting surface of the display panel and the light-emitting surface of the flat lens 23 can also be used as the distance between the display panel 21 and the flat lens 23. Specifically, the distance between the center point of the light-emitting surface of the display panel and the flat lens 23, or the distance between the center points of the light-emitting surface of the flat lens 23, can be used as the distance between the display panel 21 and the flat lens 23; The distance between the backlight surface of the display panel and the light-emitting surface of the flat lens 23 can also be used as the distance between the display panel 21 and the flat lens 23. Specifically, the distance between the center point of the backlight surface of the display panel and the flat lens 23, or the distance between the center points of the light-emitting surface of the flat lens 23, can be used as the distance between the display panel 21 and the flat lens 23; The distance between the backlight surface of the display panel and the light-incident surface of the flat lens 23 can also be used as the distance between the display panel 21 and the flat lens 23. Specifically, the distance between the center point of the backlight surface of the display panel and the flat lens 23, or the distance between the center points of the light-emitting surface of the flat lens 23, can be used as the distance between the display panel 21 and the flat lens 23.

[0058] In some embodiments, such as Figures 3 to 6 As shown, the minimum distance between the flat lens 23 and the display panel 21 is the first distance L1, and the maximum distance between the flat lens 23 and the display panel 21 is the second distance L2. The minimum distance L3 between the dimming structure 22 and the display panel 21 is one-third to one-half of the first distance L1, and the maximum distance L4 between the dimming structure 22 and the display panel 21 is one-third to one-half of the second distance. This allows the dimming structure 22 to adjust the angle of the light emitted from the display panel 21, resulting in a larger angle of light emitted from the flat lens 23 and a better display effect.

[0059] In some embodiments, such as Figures 3 to 6 As shown, a second angle b3 is formed between the plane where the display panel 21 is located and the plane where the dimming structure 22 is located. By forming a second angle between the plane where the display panel 21 is located and the plane where the dimming structure 22 is located, the dimming structure 22 can adjust the angle of the light, so that the light emitted from the display panel 21 has a larger angle after exiting the flat lens 23, resulting in a better display effect.

[0060] Specifically, the second included angle b3 is greater than or equal to 0 and less than or equal to 45 degrees.

[0061] Specifically, the second included angle b3 is greater than 0 and less than or equal to 45 degrees. The second included angle b3 can be 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, 29 degrees, 30 degrees, 31 degrees, 32 degrees, 33 degrees, 34 degrees, 35 degrees, 36 degrees, 37 degrees, 38 degrees, 39 degrees, 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees, or 45 degrees.

[0062] Specifically, the angle of the first included angle b2 can be less than 45 degrees.

[0063] In some embodiments, such as Figures 3 to 6 As shown, the angle b2 of the first included angle is less than or equal to 30 degrees. By making the angle b2 of the first included angle less than or equal to 30 degrees, the thickness of the display device can be reduced.

[0064] Specifically, the first included angle b2 can be 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, 29 degrees, 30 degrees, 31 degrees, 32 degrees, 33 degrees, 34 degrees, 35 degrees, 36 degrees, 37 degrees, 38 degrees, 39 degrees, 40 degrees, 41 degrees, 42 degrees, 43 degrees, or 44 degrees.

[0065] Specifically, the angle of the third included angle b1 can be greater than or equal to 30 degrees and less than or equal to 45 degrees.

[0066] Specifically, the plane on which the display panel 21 is located can be the plane on which the center line of the display panel 21 is located, the plane on which the light-emitting surface of the display panel 21 is located, or the plane on which the backlight surface of the display panel 21 is located.

[0067] Specifically, the plane on which the dimming structure 22 is located can be the plane on which the center line of the dimming structure 22 is located, the plane on which the vertex of the light-emitting surface of the dimming structure 22 is located, or the plane on which the light-incident surface of the dimming structure 22 is located.

[0069] Specifically, in the accompanying drawings of this utility model embodiment, the distance between the left side of the dimming structure 22 and the display panel 21 is greater than the distance between the right side of the dimming structure 22 and the display panel 21, as an example. However, this utility model embodiment is not limited to this, and the distance between the right side of the dimming structure 22 and the display panel 21 can be greater than the distance between the left side of the dimming structure 22 and the display panel 21.
