[0045] The following describes the embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0046] Those skilled in the art will understand that, unless otherwise stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of this application refers to the presence of the described features, integers, elements and / or components, but does not exclude the implementation of other features, information, data, elements, components and / or combinations thereof supported by this technical field. It should be understood that when we say that an element is "connected" or "coupled" to another element, the element can be directly connected or coupled to the other element, or it can refer to the establishment of a connection relationship between the element and the other element through an intermediate element. In addition, the "connection" or "coupling" used here may include wireless connection or wireless coupling. The term "and / or" used here refers to at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or as "B", or as "A and B".

[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] First, several terms involved in this application are introduced and explained:

[0049] Haze is the ratio of the scattered light flux that deviates from the direction of the incident light passing through a sample to the transmitted light flux, usually expressed as a percentage. Haze characterizes the turbidity and irregularity within a transparent or translucent material. The greater the haze, the greater the material's ability to scatter light, making it less visible to the human eye. For example, if you stand on the other side of frosted glass, the view on the other side is unclear, even though the glass is transparent.

[0050] Transmittance, often expressed as a percentage, is the ratio of the luminous flux passing through a specimen to the luminous flux incident on it. Transmittance can be understood as a measure of the ability of light to penetrate a material and has nothing to do with the direction of light propagation after transmission. The higher the transmittance, the more light is transmitted.

[0051] Diffuse reflection refers to the phenomenon that the light path changes when it hits an uneven surface.

[0052] Scattering refers to the phenomenon that when a light beam passes through an inhomogeneous medium, part of the light beam will deviate from its original direction and spread out in a dispersed manner, and the light can also be seen from the side.

[0053] The research and development ideas of this application include: transparent display technology can be realized by setting transparent areas and opaque areas on the display panel, wherein the opaque area can be used to arrange the driving TFT (Thin Film Transistor) and light-emitting pixels. However, in existing transparent display products, such as Figure 1 As shown, a single pixel corresponds to a transparent area, so the size of each transparent area is limited. A transparent area that is too small will form a grating structure, which is easy to cause a diffraction effect on light. When observed by the human eye, ghosting will easily occur, seriously affecting the quality of transparent display.

[0054] Increasing the size of the transparent area can effectively improve the negative impact of the diffraction effect. However, simply increasing the size of a single transparent area, that is, increasing the area ratio of the transparent area in the display panel, will inevitably affect the playback image quality of the entire display panel.

[0055] The transparent display unit, display panel, and display device provided in this application are intended to solve the above technical problems in the prior art.

[0056] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. It should be noted that the following embodiments can refer to, draw on, or combine with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0057] The embodiment of the present application provides a transparent display unit 100. The structural diagram of the transparent display unit 100 is shown in FIG. Figure 2 As shown, it includes: a display unit area 110 and a transparent area 120 connected to each other.

[0058] The transparent area 120 includes a first transparent sub-area 121 and a second transparent sub-area 122 surrounding at least a portion of the first transparent sub-area 121 ; the haze of the second transparent sub-area 122 is not less than 5%.

[0059] In this embodiment, the transparent area 120 adopts a transparent area 120 structure in which the first transparent sub-area 121 is the main light-transmitting area, and the second transparent sub-area 122 with a haze of not less than 5% surrounds at least a portion of the first transparent sub-area 121. The second transparent sub-area 122 can affect the light path outside at least a portion of the first transparent sub-area 121, so that the ambient light passing through the second transparent sub-area 122 can change the light path, making the light output direction and range larger, thereby interfering with the light path of the pinhole imaging, weakening the diffraction phenomenon, and improving the ghosting phenomenon caused by diffraction.

[0060] Optionally, the second transparent sub-area symmetrically surrounds the first transparent sub-area. Symmetry can be achieved, for example, by central symmetry or axisymmetry. This arrangement of the second transparent sub-area symmetrically surrounding the first transparent sub-area can help alleviate ghosting caused by diffraction at various viewing angles of the transparent area 120.

[0061] Optionally, the projection of the first transparent sub-area 121 on the plane where the transparent display unit 100 is located is a polygon such as a triangle, a quadrilateral, a pentagon, or a circle, or an ellipse, and the projection of the second transparent sub-area 122 on the plane where the transparent display unit 100 is located corresponds to a polygon such as a three-sided ring, a four-sided ring, a pentagon, or a circular ring, or an elliptical ring.

[0062] Based on any of the foregoing embodiments, in some possible implementations, the transmittance of the second transparent sub-region 122 is not less than 70% of the transmittance of the first transparent sub-region 121 .

[0063] In this embodiment, the transmittance of the second transparent sub-region 122 is not less than 70% of the transmittance of the first transparent sub-region 121 , which helps to ensure the transparency effect of the transparent display unit 100 , that is, the clarity of the transparency.

[0064] In some possible implementations, the area of ​​the second transparent sub-region 122 is not less than 5% of the area of ​​the first transparent sub-region 121 , and the area of ​​the second transparent sub-region 122 is not more than 30% of the area of ​​the first transparent sub-region 121 .

[0065] In this embodiment, by controlling the area ratio of the second transparent sub-area 122, it is ensured that the second transparent sub-area 122 can interfere with the optical path of the pinhole imaging, weaken the diffraction phenomenon, and control the excessive restriction that the second transparent sub-area 122 may bring to the transparent effect of the transparent display unit 100.

[0066] In one example, if Figure 2 As shown, the projection of the first transparent sub-area 121 on the plane where the transparent display unit 100 is located is a rectangle, and the projection of the second transparent sub-area 122 on the plane where the transparent display unit 100 is located is a rectangular ring.

[0067] Among them, the outer dimension of the first transparent sub-area 121 in the first direction (taking the length direction as an example) is d1, the outer dimension of the first transparent sub-area 121 in the second direction (taking the width direction as an example) is d2, the outer dimension of the second transparent sub-area 122 in the first direction is d3, and the outer dimension of the second transparent sub-area 122 in the second direction is d4. The first direction is orthogonal to the second direction and both are parallel to the plane where the transparent display unit 100 is located.

[0068] At this time, the area of ​​the second transparent sub-region 122 and the area of ​​the first transparent sub-region 121 can be represented by the formula (d3*d4-d1*d2) / d1*d2, 5%≤(d3*d4-d1*d2) / d1*d2≤30%.

[0069] To achieve the haze of the second transparent sub-region 122 provided in the aforementioned embodiment being not less than 5%, and / or the transmittance of the second transparent sub-region 122 being not less than 70% of the transmittance of the first transparent sub-region 121, the present application provides the following three possible implementations for the specific structure of the transparent region 120 in the transparent display unit 100:

[0070] In a first possible implementation, Figure 3 As shown, the first transparent sub-area 121 includes a first transparent structure 11; the second transparent sub-area 122 includes a second transparent structure 12, and the second transparent structure 12 includes at least one of a diffuse reflection layer, a scattering layer and an anisotropic layer.

[0071] In this embodiment, the first transparent structure 11 of the first transparent sub-region 121 and the second transparent structure 12 of the second transparent sub-region 122 are manufactured separately. The first transparent structure 11 can be manufactured first and then the second transparent structure 12, or vice versa.

[0072] The second transparent structure 12 can utilize at least one film layer selected from the group consisting of a diffuse reflection layer, a scattering layer, and an anisotropic layer to adjust the haze and / or transmittance.

[0073] Optionally, when the second transparent structure 12 is formed by combining the at least two film layers mentioned above, the at least two film layers may be arranged in a stacked manner.

[0074] Optionally, the diffuse reflection layer includes: a light-transmitting material with scattering particles on the surface, or a patterned semi-transmissive and semi-reflective layer.

[0075] Optionally, the scattering layer includes: a light-transmitting material in which scattering particles 13 are suspended, or a microlens structure. That is, the scattering layer employs an MLA (Micro Lens Array, which may include microlenses and / or scattering particles) structure. For example, the scattering layer may adjust the haze and / or transmittance by mixing the scattering particles 13 into the light-transmitting material.

[0076] Optionally, the MLA may be a convex lens made of transparent resin, PI (Polyimide), or acrylic (also called PMMA or organic glass), and the scattering effect is mainly determined by the sag diameter and the duty cycle.

[0077] Optionally, the anisotropic layer or birefringent material may be a polycrystalline material, in which the molecules are arranged in an orderly manner and birefringence is likely to occur at the crystal interface, thereby increasing the light output range.

[0078] Optionally, the scattering layers in the first transparent structure 11 and the second transparent structure 12 can be prepared separately based on the same light-transmitting material. The difference is that: in the process of preparing the first transparent structure 11, the light-transmitting material is directly deposited or coated, and then patterned; in the process of preparing the scattering layer in the second transparent structure 12, it is necessary to first mix scattering particles 13 into the light-transmitting material to obtain a mixed material, and then the mixed material is deposited or coated, and then patterned.

[0079] In a second possible implementation, Figure 4 As shown, the first transparent sub-region 121 and the second transparent sub-region 122 both include a first transparent structure 11 .

[0080] The second transparent sub-region 122 further includes a dimming structure 14 located on at least one side of the first transparent structure 11 .

[0081] In this embodiment, the first transparent sub-area 121 and the second transparent sub-area 122 share the same first transparent structure 11, that is, the first transparent sub-area 121 and the second transparent sub-area 122 are different areas of the same first transparent structure 11, the difference being that a dimming structure 14 is additionally prepared on at least one side of the first transparent structure 11 located in the second transparent sub-area 122.

[0082] Specifically, a light-transmitting material may be deposited or coated and then patterned to obtain the first transparent structure 11 , and then the dimming structure 14 is prepared on one side of the first transparent structure 11 located in the second transparent sub-region 122 .

[0083] Optionally, the dimming structure includes at least one of a diffuse reflection layer, a scattering layer and an anisotropic layer.

[0084] It should be noted that the dimming structure 14 can also be obtained by processing the surface of a related structure formed of a light-transmitting material to form a surface morphology with certain scattering characteristics.

[0085] In a third possible implementation, Figure 5 As shown, the first transparent sub-region 121 and the second transparent sub-region 122 both include a first transparent structure 11 .

[0086] At least one side of the portion of the first transparent structure 11 located in the second transparent sub-region 122 has a patterned concave-convex topography 15 .

[0087] In this embodiment, the first transparent sub-area 121 and the second transparent sub-area 122 also share the same first transparent structure 11, that is, the first transparent sub-area 121 and the second transparent sub-area 122 are different areas of the same first transparent structure 11. The difference is that: a concave-convex topography 15 with certain scattering characteristics is patterned on one side of the first transparent structure 11 located in the second transparent sub-area 122.

[0088] Based on any of the above embodiments, Figure 2 As shown, the display unit area 110 includes at least two types of pixels.

[0089] In this embodiment, the transparent display unit 100 uses a transparent area 120 corresponding to at least two types of pixels (eg Figure 2 The layout of the first pixel 111 and the second pixel 112 in the transparent area 120, that is, at least two types of pixels can share a transparent area 120, can achieve the expansion of the area of ​​a single transparent area 120 without changing the area ratio of the transparent area 120. On the one hand, it can effectively reduce the degree to which a grating structure is formed in a single transparent area 120, effectively improve the negative impact of the diffraction effect, and reduce or even eliminate the ghosting phenomenon; on the other hand, it will not compress the area ratio of the display unit area 110, and can ensure the quality of the playback picture.

[0090] In some possible implementations, such as Figure 6 As shown, the display unit area 110 includes a first pixel 111 , a second pixel 112 , a third pixel 113 and a fourth pixel 114 arranged in an array.

[0091] The first pixel 111 is in the same row as the second pixel 112 , the first pixel 111 is in the same column as the third pixel 113 , the fourth pixel 114 is in the same column as the second pixel 112 , and the fourth pixel 114 is in the same row as the third pixel 113 .

[0092] In this embodiment, the display unit area 110 includes four pixels arranged in an array, which facilitates the transparent display unit 100 to achieve full-color gamut display. Pixels within the same display unit area 110 share the same transparent area 120. Compared to a solution where each pixel corresponds to a single transparent area 120, this facilitates quadrupling the area of ​​a single transparent area 120 without changing the area ratio of the transparent area 120. This effectively mitigates the negative effects of diffraction effects, reduces or even eliminates ghosting, and maintains playback image quality without compromising the area ratio of the display unit area 110.

[0093] Optionally, the first pixel 111 , the second pixel 112 , the third pixel 113 and the fourth pixel 114 include at least one red pixel, one green pixel and one blue pixel.

[0094] In this embodiment, the transparent display unit 100 realizes full color gamut display by utilizing the principle that the three primary colors of red, green, and blue can generate various colored lights by adding them in different proportions.

[0095] Optionally, based on the previous embodiment, a white pixel is further included in the first pixel 111, the second pixel 112, the third pixel 113, and the fourth pixel 114. That is, the first pixel 111, the second pixel 112, the third pixel 113, and the fourth pixel 114 respectively include a red pixel, a green pixel, a blue pixel, and a white pixel.

[0096] In this embodiment, adding white pixels is beneficial to increasing the luminous brightness of the display unit area 110 in the transparent display unit 100 and improving the quality of the playback image.

[0097] Based on any of the foregoing embodiments, in some possible implementations, such as Figure 1 and Figure 6 As shown, the transparent display unit 100 further includes: a unit wiring area 130 connected to the display unit area 110 .

[0098] The projection of the unit wiring area 130 on the plane where the transparent display unit 100 is located is outside the projection of the transparent area 120 on the plane where the transparent display unit 100 is located.

[0099] In this embodiment, the unit wiring area 130 of the transparent display unit 100 is used to route wires, thereby enabling driving of each pixel in the display unit area 110. The projection of the unit wiring area 130 on the plane where the transparent display unit 100 is located is outside the projection of the transparent area 120 on the plane where the transparent display unit 100 is located, which can effectively reduce light obstruction caused by the wires in the unit wiring area 130.

[0100] Optionally, at least part of the unit wiring area 130 is located between the transparent area 120 and the display unit area 110. This can increase the contact area between the unit wiring area 130 and the display unit area 110, and facilitate electrical connection between the wires in the unit wiring area 130 and each pixel in the display unit area 110.

[0101] Based on the same inventive concept, the embodiment of the present application provides a display panel 200, such as Figure 7 As shown, the display panel 200 includes: any one of the transparent display units 100 provided in the aforementioned embodiments.

[0102] In this embodiment, since the display panel 200 includes any one of the transparent display units 100 provided in the aforementioned embodiments, the implementation principles and beneficial effects thereof are similar and will not be described in detail herein.

[0103] Optionally, the transparent display unit 100 may be located in a portion of the display area of ​​the display panel, or may be distributed in the entire display area of ​​the display panel.

[0104] Optionally, the transparent display units 100 may be arranged in an array.

[0105] Based on the same inventive concept, an embodiment of the present application provides a display device, and the display panel includes: any one of the display panels provided in the aforementioned embodiments.

[0106] In this embodiment, since the display device includes any one of the display panels provided in the aforementioned embodiments, its implementation principles and beneficial effects are similar and will not be described in detail here.

[0107] Optionally, the display device may include a mobile phone, a tablet computer, a mobile terminal, an e-book, an electronic photo frame, an electronic billboard, and the like.

[0108] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0109] 1. The transparent area 120 adopts a structure in which the first transparent sub-area 121 is the main light-transmitting area, and the second transparent sub-area 122 with a haze of not less than 5% surrounds at least a portion of the first transparent sub-area 121. The second transparent sub-area 122 can affect the light path of at least a portion of the periphery of the first transparent sub-area 121, so that the ambient light passing through the second transparent sub-area 122 can change the light path, making the light output direction and range larger, thereby interfering with the optical path of the pinhole imaging, weakening the diffraction phenomenon, and improving the ghosting phenomenon caused by diffraction.

[0110] 2. The transmittance of the second transparent sub-region 122 is not less than 70% of the transmittance of the first transparent sub-region 121 , which is beneficial to ensuring the transparency effect of the transparent display unit 100 , that is, the clarity of the transparency.

[0111] 3. By controlling the area ratio of the second transparent sub-area 122 , it is ensured that the second transparent sub-area 122 can interfere with the optical path of the pinhole imaging, weaken the diffraction phenomenon, and control the excessive restriction that the second transparent sub-area 122 may bring to the transparent effect of the transparent display unit 100 .

[0112] 4. The first transparent structure 11 of the first transparent sub-area 121 and the second transparent structure 12 of the second transparent sub-area 122 are manufactured separately. The haze and / or transmittance of the second transparent structure 12 can be adjusted by mixing scattering particles 13 into the transparent material.

[0113] 5. The transparent display unit 100 adopts a layout in which one transparent area 120 corresponds to at least two pixels. That is, at least two pixels can share one transparent area 120. This can achieve the expansion of the area of ​​a single transparent area 120 without changing the area ratio of the transparent area 120. On the one hand, it can effectively reduce the degree to which a single transparent area 120 forms a grating structure, effectively improve the negative impact of the diffraction effect, and reduce or even eliminate the ghosting phenomenon. On the other hand, it does not compress the area ratio of the display unit area 110, and can ensure the quality of the playback image.
