DETAILED DESCRIPTION

[0026] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and techniques are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of regional structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0027] In the related art, an interfering sub-pixel is set, and a black shading layer is set on the top of the interfering sub-pixel to block the light emission of the sub-pixel at a normal viewing angle, thereby limiting the light emission of the interfering sub-pixel at a small angle, thereby affecting the normal pixel display while avoiding wide-angle visibility.

[0028] However, in the related art, providing interference pixels and black light shielding layers corresponding to the interference sub-pixels reduces the aperture ratio of the display panel, reduces the brightness of the display panel, and results in a poor user experience.

[0029] In view of this, an embodiment of the present application provides a display panel and a preparation method, which increases the aperture ratio of the display sub-pixel by making the distance between the first shading unit and the array substrate smaller than the distance between the color resist layer and the array substrate, thereby improving the display brightness of the display panel.

[0030] The specific structures and processes of the display panels and manufacturing methods provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0031] First embodiment

[0032] Figure 1 is a schematic diagram showing the structure of a first display panel provided in the first embodiment of the present application. Figure 6 is a schematic diagram showing a top view of the structure of a display panel provided in an embodiment of the present application.

[0033] As shown in FIG1 and FIG6 , the first embodiment of the present application provides a display panel 100 , which includes an array substrate 50 and a light-emitting functional layer 10 , an encapsulation layer 20 , a light-shielding layer 30 and a color resist layer 40 sequentially formed on the array substrate 50 .

[0034] As shown in Figure 6, the light-emitting functional layer 10 includes a plurality of pixel units 13 distributed in an array, at least some of the pixel units 13 include a plurality of display sub-pixels 11 and at least one interference sub-pixel 12. As shown in Figure 1, the shading layer 30 includes a first shading unit 31 corresponding to the interference sub-pixel 12, and the color resist layer 40 corresponds to the display sub-pixel 11.

[0035] The distance between the color resist layer 40 and the array substrate 50 is greater than the distance between the first light shielding unit 31 and the array substrate 50 .

[0036] Specifically, the display panel has an anti-peeping mode. When the anti-peeping mode is off, the display sub-pixel 11 displays normally, the interfering sub-pixel 12 is off, and the display panel can clearly display when viewed straight on or at an angle. When the anti-peeping mode is on, the interfering sub-pixel 12 is turned on, and the forward light emitted by the interfering sub-pixel 12 is blocked by the first light shielding unit 31. The forward light emitted by the display sub-pixel 11 is not interfered with, and the display panel can clearly display when viewed straight on. The oblique light emitted by the interfering sub-pixel 12 is not blocked by the first light shielding unit 31, and the oblique light emitted by the display sub-pixel 11 will mix with the oblique light emitted by the interfering sub-pixel 12. The display panel cannot clearly display when viewed at an angle, thereby achieving an anti-peeping effect.

[0037] As shown in Figure 1 , compared to the position of the first light shielding unit 31 (indicated by the dotted line) in the prior art, the present invention lowers the first light shielding unit 31, thereby reducing the obstruction of light emitted by the display sub-pixel 11, increasing the aperture ratio of the display sub-pixel 11, and thereby improving the brightness of the display panel. In other words, the height of the interference sub-pixel 12 and the display sub-pixel 11 relative to the array substrate 50 can be the same, and the height of the first light shielding unit 31 relative to the array substrate 50 can be less than the height of the color-resistance layer 40 relative to the array substrate 50. This allows some light to be emitted from the corners of the color-resistance layer 40, thereby increasing the light output angle and light output rate.

[0038] Furthermore, the first shading unit 31 may be trapezoidal, with the sides of the trapezoid parallel to the light emitted at the maximum angle from the display sub-pixel 11, further reducing the blocking of the light emitted from the display sub-pixel 11. In other embodiments, the first shading unit 31 may also be rectangular.

[0039] In this embodiment, by sinking the position of the first shading unit 31, the distance between the first shading unit 31 and the array substrate 50 is made smaller than the distance between the color resist layer 40 and the array substrate 50, thereby reducing the obstruction of the light emitted by the display sub-pixel 11, increasing the aperture ratio of the display sub-pixel 11, and thereby improving the display brightness of the display panel and enhancing the user experience.

[0040] Figure 2 shows a schematic diagram of the structure of the second display panel provided by the first embodiment of the present application. Because the position of the first light shielding unit 31 is sunken, the obstruction of light emitted by the display sub-pixel 11 is reduced. Therefore, the display sub-pixel 11 in the present application can be designed to be larger in size. That is, the size of the display sub-pixel 11 in the present application is larger than the size of the display sub-pixel 11 in the related art (indicated by the dotted line), which is beneficial for increasing the aperture ratio of the display panel and thus improving the display brightness of the display panel.

[0041] FIG3 is a schematic diagram showing the structure of the third display panel provided by the first embodiment of the present application. (a) is a schematic diagram showing the structure of a display panel in the related art, and (b) is a schematic diagram showing the structure of a display panel in the present application. Since the position of the first light shielding unit 31 is lowered, the blocking of the light emitted by the display sub-pixel 11 is reduced. Therefore, in the present application, the distance between the display sub-pixel 11 and the interfering sub-pixel 12 is shortened without changing the size of the display sub-pixel 11 and the interfering sub-pixel 12. That is, more display sub-pixels 11 and interfering sub-pixels 12 are provided in the display panel to improve the resolution of the display panel.

[0042] In some embodiments, the encapsulation layer 20 includes a first encapsulation unit 21 corresponding to the interference sub-pixel 12 and a second encapsulation unit 22 corresponding to the display sub-pixel 11 . The thickness of the first encapsulation unit 21 is smaller than that of the second encapsulation unit 22 .

[0043] Specifically, the encapsulation layer 20 includes a first inorganic layer 23 , an organic layer 24 and a second inorganic layer 25 sequentially arranged in a direction away from the array substrate 50 . The thickness of the organic layer 24 corresponding to the first encapsulation unit 21 is less than the thickness of the organic layer 24 corresponding to the second encapsulation unit 22 .

[0044] That is, the difference between the distance between the color resist layer 40 and the array substrate 50 and the distance between the first light shielding unit 31 and the array substrate 50 is equal to the difference between the thickness of the first encapsulation unit 21 and the thickness of the second encapsulation unit 22. This difference is specifically the difference between the thickness of the organic layer 24 corresponding to the first encapsulation unit 21 and the thickness of the organic layer 24 corresponding to the second encapsulation unit 22.

[0045] Furthermore, the thickness of the organic layer 24 corresponding to the first encapsulation unit 21 may be 0, further increasing the aperture ratio of the display sub-pixel 11 .

[0046] It is worth noting that the thickness of the first inorganic layer 23 corresponding to the first encapsulation unit 21 is equal to the thickness of the first inorganic layer 23 corresponding to the second encapsulation unit 22, and the thickness of the second inorganic layer 25 corresponding to the first encapsulation unit 21 is equal to the thickness of the second inorganic layer 25 corresponding to the second encapsulation unit 22. This application reduces the thickness of the organic layer 24 in the first encapsulation unit 21 without changing the thickness of the first inorganic layer 23 and the second inorganic layer 25 in the first encapsulation unit 21, thereby lowering the position of the first light shielding unit 31, avoiding defects such as holes and cracks caused by etching the first inorganic layer 23 or the second inorganic layer 25, which facilitates the subsequent packaging of the display panel.

[0047] In some embodiments, the first encapsulation unit 21 is formed with a first groove 211, and the first light-shielding unit 31 is located within the first groove 211. Specifically, the color-resistance layer 40 covers the edge of the first light-shielding unit 31, and the thickness of the color-resistance layer 40 covering the edge of the first light-shielding unit 31 is greater than the thickness of the color-resistance layer 40 covering the second encapsulation unit 22. That is, the upper surface of the first light-shielding unit 31 can also be lower than the upper surface of the second inorganic layer 25 corresponding to the second encapsulation unit 22, allowing more light to be emitted from the junction of the first light-shielding unit 31 and the second encapsulation unit 22, thereby ensuring that the display sub-pixel 11 has a larger light emission angle.

[0048] As shown in Figures 1, 2, and 3, the color resist layer 40 covers the edge of the first light-shielding unit 31, that is, the sidewall of the first groove 211 is provided with the color resist layer 40. The light emitted by the display sub-pixel 11 passes through the sidewall of the first groove 211 and then passes through the color resist layer 40 before being emitted, ensuring that the light emitted by the display sub-pixel 11 enters the human eye after passing through the color resist layer 40.

[0049] In this embodiment, by lowering the position of the first light shielding unit 31, the distance between the first light shielding unit 31 and the array substrate 50 is smaller than the distance between the color resist layer 40 and the array substrate 50. This reduces the obstruction of light emitted by the display sub-pixel 11, increases the aperture ratio of the display sub-pixel 11, and thereby improves the display brightness of the display panel and enhances the user experience. By reducing the thickness of the organic layer 24 in the first encapsulation unit 21 without changing the thickness of the first inorganic layer 23 and the second inorganic layer 25 in the first encapsulation unit 21, the position of the first light shielding unit 31 is lowered, thereby preventing defects such as holes and cracks in the first inorganic layer 23 or the second inorganic layer 25, and facilitating subsequent packaging of the display panel. The sidewalls of the first groove 211 are provided with a color resist layer 40. Light emitted by the display sub-pixel 11 passes through the sidewalls of the first groove 211 and then through the color resist layer 40 before exiting, ensuring that the light emitted by the display sub-pixel 11 enters the human eye after passing through the color resist layer 40.

[0050] Second embodiment

[0051] FIG4 shows a schematic structural diagram of a display panel provided in a second embodiment of the present application.

[0052] As shown in Figure 4, the second embodiment of the present application provides a display panel, which is similar in structure to the display panel shown in the first embodiment and Figures 1, 2 and 3, except that the color resist layer 40 includes multiple color resist units 41, and the shading layer 30 also includes a second shading unit 32, the second shading unit 32 is located between two adjacent color resist units 41, and the distance between the color resist layer 40 and the array substrate 50 is greater than the distance between the second shading unit 32 and the array substrate 50.

[0053] The color resist unit 41 includes a red color resist, a green color resist and a blue color resist.

[0054] By sinking the position of the second shading unit 32, the distance between the second shading unit 32 and the array substrate 50 is made smaller than the distance between the color resist layer 40 and the array substrate 50, thereby reducing the obstruction of the light emitted by the display sub-pixel 11, increasing the aperture ratio of the display sub-pixel 11, and thereby improving the display brightness of the display panel and enhancing the user experience.

[0055] In some embodiments, the encapsulation layer 20 further includes a third encapsulation unit 26 located between the two second encapsulation units 22. The third encapsulation unit 26 is formed with a second groove 221. The second light shielding unit 32 is located in the second groove 221. Specifically, the edge of the color resist layer 40 also covers the second light shielding unit 32.

[0056] That is, a color resist layer 40 is provided on the sidewall of the second groove 221 , and the light emitted by the display sub-pixel 11 passes through the sidewall of the second groove 221 and then through the color resist layer 40 before being emitted, ensuring that the light emitted by the display sub-pixel 11 enters the human eye after passing through the color resist layer 40 .

[0057] In other embodiments, the position of the second shading unit 32 is not sunken, and is the same as the position in the related art. Only the first shading unit 31 is sunken, and its beneficial effects are the same as those of the first embodiment, which will not be repeated here.

[0058] In this embodiment, by sinking the second shading unit 32, the distance between the second shading unit 32 and the array substrate 50 is made smaller than the distance between the color resist layer 40 and the array substrate 50, thereby reducing the obstruction of the light emitted by the display sub-pixel 11, further increasing the aperture ratio of the display sub-pixel 11, and improving the display brightness of the display panel.

[0059] Third embodiment

[0060] FIG5 is a schematic flow chart showing a method for manufacturing a display panel according to a third embodiment of the present application.

[0061] As shown in FIG5 , the third embodiment of the present application provides a method for manufacturing the display panel as mentioned above, the method comprising:

[0062] Step S101: providing an array substrate.

[0063] Step S102: forming a patterned light-emitting functional layer by evaporation on the array substrate.

[0064] The light-emitting functional layer includes a plurality of pixel units distributed in an array, and at least part of the pixel units includes a plurality of display sub-pixels and at least one interference sub-pixel.

[0065] Step S103: forming a patterned encapsulation layer on the light-emitting functional layer.

[0066] Step S104: forming a patterned light shielding layer on the packaging layer.

[0067] The light shielding layer includes a first light shielding unit corresponding to the interference sub-pixel.

[0068] Step S105: forming a patterned color resist layer on the encapsulation layer.

[0069] The distance between the color resist layer and the array substrate is greater than the distance between the first light shielding unit and the array substrate.

[0070] In this embodiment, a patterned light-emitting functional layer is formed by vapor deposition on an array substrate, a patterned encapsulation layer is formed on the light-emitting functional layer, a patterned light-shielding layer is formed on the encapsulation layer, and a patterned color-resist layer is formed on the encapsulation layer. The distance between the color-resist layer and the array substrate is greater than the distance between the first light-shielding unit and the array substrate. By making the distance between the first light-shielding unit and the array substrate smaller than the distance between the color-resist layer and the array substrate, the aperture ratio of the display sub-pixels is increased, thereby improving the display brightness of the display panel.

[0071] In some embodiments, the encapsulation layer includes a first encapsulation unit corresponding to the interference sub-pixel and a second encapsulation unit corresponding to the display sub-pixel, and step S103 specifically includes:

[0072] Step S201: depositing a first inorganic layer on the light-emitting functional layer.

[0073] Step S202 : depositing an initial organic layer on the first inorganic layer, and patterning the initial organic layer to form a first groove and a second groove.

[0074] The first groove corresponds to the first packaging unit, and the second groove corresponds to the second packaging unit.

[0075] Step S203: depositing a second inorganic layer on the organic layer.

[0076] It is worth noting that the thickness of the first inorganic layer corresponding to the first encapsulation unit is equal to the thickness of the first inorganic layer corresponding to the second encapsulation unit, and the thickness of the second inorganic layer corresponding to the first encapsulation unit is equal to the thickness of the second inorganic layer corresponding to the second encapsulation unit. This application reduces the thickness of the organic layer in the first encapsulation unit without changing the thickness of the first and second inorganic layers in the first encapsulation unit, thereby lowering the position of the first light-shielding unit, avoiding defects such as holes and cracks in the first or second inorganic layers, and facilitating subsequent packaging of the display panel.

[0077] It should be readily understood that “on,” “above,” and “over” in this application should be interpreted in the broadest manner, such that “on” means not only “directly on something,” but also includes “on something” with intervening features or layers therebetween, and “above” or “over” includes not only the meaning of “above” or “over,” but also includes the meaning of “above” or “over” with no intervening features or layers therebetween (i.e., directly on something).

[0078] The term "layer" as used herein may refer to a material portion comprising an area having a certain thickness. A layer may extend over the entire underlying structure or overlying structure, or may have a range smaller than the range of the underlying or overlying structure. In addition, a layer may be an area of ​​a homogeneous or inhomogeneous continuous structure, the thickness of which is less than the thickness of the continuous structure. For example, a layer may be located between the top surface and the bottom surface of the continuous structure or between any paired transverse planes at the top surface and the bottom surface. A layer may extend laterally, vertically and / or along a tapered surface. An array substrate may be a layer, may include one or more layers therein, and / or may have one or more layers located thereon, above it and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductors and a contact layer (forming contacts, interconnect lines and / or vias therein) and one or more dielectric layers.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
