[0025] In recent years, anti-peeping display has attracted much attention. There are many application scenarios for anti-peeping display. For example, when it is displayed in a car, it needs to be vertically anti-peeping to suppress light pollution; at the same time, it needs to be displayed normally horizontally so that the driver can watch and operate. For another example, when it is displayed on the co-pilot of the car, it needs to be all-round anti-peeping to suppress light pollution and prevent the driver from being distracted. For another example, privacy needs to be protected in some special occasions. The diversity of anti-peeping application scenarios has greatly promoted the development of anti-peeping display.

[0026] However, due to process limitations, current anti-peeping display products have low layout space utilization.

[0027] In view of this, the embodiments of the present application provide a display panel and a display device, which improve the layout space utilization by arranging electrically connected shared sub-pixels and anti-peeping sub-pixels adjacent to each other instead of arranging them diagonally and staggered.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is understood that when a structure is referred to as being "on or under" another structure, the structure may be directly on or under the other structure, or there may be intermediate structures. The same reference numerals always indicate the same structure. The structures mentioned herein include any of a film layer, an element, a device, a component, and an assembly.

[0030] When a structure is referred to as being “connected” to another structure, the structure may be directly connected to the other structure or indirectly connected to the other structure with one or more intermediate structures interposed therebetween.

[0031] In this specification, "electrical connection" includes the case where components are connected together through an element having some electrical function. There is no particular limitation on the "element having some electrical function" as long as it can transmit and receive electrical signals between the connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having various functions.

[0032] In this specification, the term “same-layer arrangement” refers to a structure in which two (or more) structures are formed by the same patterning process, and their materials may be the same or different.

[0033] Figure 1This is a schematic diagram of the top structure of the display panel provided in the first embodiment of the present application. Figure 2 for Figure 1 The cross-sectional structure diagram of the display panel along the A1A2 line is shown. Figure 1 and Figure 2 As shown, the display panel includes: a substrate 10, a plurality of pixel circuits 20 and at least one pixel group 30. The plurality of pixel circuits 20 are located on one side of the substrate 10. The pixel group 30 includes a plurality of sub-pixels 300, and the sub-pixels 300 are located on the side of the pixel circuit 20 away from the substrate 10. The plurality of sub-pixels 300 in the pixel group 30 are connected to the same pixel circuit 20, and the plurality of sub-pixels 300 include a shared sub-pixel 310 and at least two anti-peeping sub-pixels 320, and the shared sub-pixels 310 and at least two anti-peeping sub-pixels 320 in the same pixel group 30 are arranged linearly.

[0034] The substrate 10 may be a glass-based substrate. In some embodiments, the substrate substrate may include an organic resin material such as epoxy resin, triazine, silicone resin, or polyimide. In some embodiments, the substrate substrate may include a ceramic material such as silicon nitride, aluminum nitride, or aluminum oxide, or may include a metal or a metal compound.

[0035] The pixel circuit 20 is electrically connected to the sub-pixel 300, and is used to drive the sub-pixel 300 to emit light to achieve a display function. In this embodiment, the pixel circuit 20 connects a plurality of sub-pixels 300 in a pixel group 30, and the plurality of sub-pixels 300 include a shared sub-pixel 310 and at least one anti-peeping sub-pixel 320. The pixel circuit 20 includes a pixel driving module and a selection module. The pixel driving module is, for example, a 7T1C, 8T1C or other driving module. The selection module is used to selectively connect the shared sub-pixel 310 or the anti-peeping sub-pixel 320 to the pixel driving module. When the pixel driving module is connected to the shared sub-pixel 310, the pixel group 30 is used for conventional display; when the pixel driving module is connected to the anti-peeping sub-pixel 320, the pixel group 30 is used for anti-peeping display.

[0036] The sub-pixel 300 may be an organic light-emitting diode (OLED), a micro light-emitting diode (Micro LED), a quantum dot light-emitting diode (QLED), or the like.

[0037] According to the display panel provided in this embodiment, by arranging the shared sub-pixel 310 and at least two anti-peeping sub-pixels 320 in the same pixel group 30 in a linear manner, the distance between the shared sub-pixel 310 and the anti-peeping sub-pixel 320 is shortened compared to the conventional staggered arrangement of the shared sub-pixel 310 and the anti-peeping sub-pixel 320 in the same pixel group 30, thereby improving the layout space utilization of the display panel and reducing the cross-capacitance of the pixel circuit 20.

[0038] In one embodiment, Figure 1 As shown, at least two anti-peeping sub-pixels 320 include a first anti-peeping sub-pixel 321 and a second anti-peeping sub-pixel 322. The shared sub-pixel 310, the first anti-peeping sub-pixel 321, and the second anti-peeping sub-pixel 322 are linearly arranged in sequence along the first direction x.

[0039] In one embodiment, Figure 1 As shown, the distance between the shared sub-pixel 310 and the first anti-peeping sub-pixel 321 is greater than or equal to 5 micrometers and less than or equal to 24 micrometers. For example, the distance is 5 micrometers, 10 micrometers, 15 micrometers, 20 micrometers, etc.

[0040] In one embodiment, Figure 1 As shown, the distance between the shared sub-pixel 310 and the first anti-peeping sub-pixel 321 is greater than or equal to 8 micrometers and less than or equal to 20 micrometers. For example, the distance is 8 micrometers, 10 micrometers, 15 micrometers, 16 micrometers, 20 micrometers, etc.

[0041] In one embodiment, Figure 1 As shown, the luminous colors of the multiple sub-pixels 300 in the pixel group 30 are the same. That is, the luminous colors of the shared sub-pixels 310 and the anti-peeping sub-pixels 320 in the same pixel group 30 are the same.

[0042] In one embodiment, Figure 1 As shown, at least one pixel group 30 includes a plurality of pixel groups 30, and the plurality of pixel groups 30 are arranged in an array along a first direction x and a second direction y intersecting the first direction x. Exemplarily, the second direction y is perpendicular to the first direction x.

[0043] In one embodiment, Figure 1 As shown, in the second direction y, the shared sub-pixels 310 in different pixel groups 30 are arranged linearly, the first anti-peeping sub-pixels 321 in different pixel groups 30 are arranged linearly, and the second anti-peeping sub-pixels 322 in different pixel groups 30 are arranged linearly.

[0044] In one embodiment, Figure 1 As shown, the aperture ratio of the shared sub-pixel 310 is greater than the aperture ratio of the anti-peep sub-pixel 320. Figure 1As shown, the aperture ratio of the shared sub-pixel 310 is equal to the sum of the aperture ratios of the first anti-peeping sub-pixel 321 and the second anti-peeping sub-pixel 322 .

[0045] In one embodiment, Figure 1 As shown, the orthographic projection of the anti-peeping sub-pixel 320 on the substrate 10 is different from the orthographic projection of the shared sub-pixel 310 on the substrate 10. Exemplarily, the orthographic projection of the anti-peeping sub-pixel 320 on the substrate 10 includes a circle. The advantage is that the 360° anti-peeping effect can be ensured to be consistent. The orthographic projection of the shared sub-pixel 310 on the substrate 10 includes a rectangle.

[0046] Figure 3 A schematic top view of the structure of a display panel provided in the second embodiment of the present application. Figure 4 for Figure 3 The cross-sectional structure diagram of the display panel along the A3A4 line is shown. Figure 3 and Figure 4 As shown, the display panel and Figure 1 , Figure 2 The difference between the display panel shown in the figure is that, in the present embodiment, the display panel further includes a first light shielding layer 41, which is located on the side of the sub-pixel 300 away from the substrate 10. The first light shielding layer 41 includes a plurality of first light shielding portions 410, and the orthographic projections of the first light shielding portions 410 on the substrate 10 surround the orthographic projections of the anti-peeping sub-pixel 320 on the substrate 10. The advantage of providing the first light shielding layer 41 is that it can prevent the anti-peeping sub-pixel 320 from leaking light and affecting the anti-peeping effect.

[0047] In one embodiment, in combination Figure 3 and Figure 4 As shown, the orthographic projection of the first light shielding portion 410 on the substrate 10 is mesh-shaped, and the first mesh holes H3 of the first light shielding portion 410 and the orthographic projection of the anti-peeping sub-pixel 320 on the substrate 10 at least partially overlap.

[0048] In one embodiment, Figure 3 As shown, the orthographic projection of the first light shielding portion 410 on the substrate 10 extends along the second direction y, and the orthographic projections of the plurality of first light shielding portions 410 on the substrate 10 are arranged along the first direction x.

[0049] Exemplarily, the orthographic projections of the anti-peeping sub-pixels 320 of the multiple pixel groups 30 arranged along the second direction y on the substrate 10 are located in different first meshes H3 of the orthographic projections of the same first shading portion 410 on the substrate 10, that is, the first shading portion 410 corresponds to the anti-peeping sub-pixels 320 of a row of pixel groups 30 in the second direction y. The orthographic projections of the shared sub-pixels 310 of the multiple pixel groups 30 arranged along the second direction y on the substrate 10 are located between the orthographic projections of the adjacent first shading portions 410 on the substrate 10. In this case, in the second direction y, the first shading portions 410 are not provided on both sides of the shared sub-pixels 310, which can ensure that the shared sub-pixels 310 have smaller brightness decay and better color deviation.

[0050] In one embodiment, Figure 4 As shown, the display panel also includes an encapsulation layer 42, which is located between the first light shielding layer 41 and the sub-pixel 300. Exemplarily, the encapsulation layer 42 includes a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer stacked in sequence in a direction away from the substrate 10. Among them, the first encapsulation layer and the third encapsulation layer are inorganic materials, and the second encapsulation layer is an organic material. The first encapsulation layer, the second encapsulation layer, and the third encapsulation layer are all complete film layers, that is, there is no graphic structure. The orthographic projection of the first encapsulation layer on the substrate 10 covers the orthographic projection of multiple sub-pixels 300 on the substrate 10. The orthographic projection of the second encapsulation layer on the substrate 10 covers the orthographic projection of multiple sub-pixels 300 on the substrate 10, and is located within the orthographic projection range of the first encapsulation layer on the substrate 10. The orthographic projection of the third encapsulation layer on the substrate 10 covers the orthographic projection of multiple sub-pixels 300 on the substrate 10, and covers the orthographic projection of the second encapsulation layer on the substrate 10.

[0051] In one embodiment, Figure 4 As shown, the display panel further includes a touch layer 43, which is located on the side of the first light shielding layer 41 away from the substrate 10. The touch layer 43 is used to implement the touch function. The touch layer 43 can be a self-capacitive touch layer or a mutual-capacitive touch layer.

[0052] In one embodiment, Figure 4 As shown, the display panel further includes a cover plate 44, which is located on the side of the touch layer 43 facing away from the substrate 10. The cover plate 44 may be made of glass to provide protection.

The second light shielding layer 45 includes a plurality of second light shielding portions 450, and the orthographic projections of the second light shielding portions 450 on the substrate 10 surround the orthographic projections of the anti-peeping sub-pixels 320 on the substrate 10.

[0056] In one embodiment, Figure 5 As shown, the orthographic projections of the anti-peeping sub-pixels 320 of the plurality of pixel groups 30 arranged along the second direction y on the substrate 10 are located in different second mesh holes H4 of the orthographic projection of the same second light shielding portion 450 on the substrate 10 .

[0057] In one embodiment, Figure 5 As shown, the orthographic projections of the shared sub-pixels 310 of the plurality of pixel groups 30 arranged along the second direction y on the substrate 10 are located between the orthographic projections of the adjacent second light shielding portions 450 on the substrate 10 .

[0058] In one embodiment, Figure 5 As shown, the orthographic projection of the first light shielding portion 410 on the substrate 10 is located within the orthographic projection range of the second light shielding portion 450 on the substrate 10. In the first direction x, the distance between adjacent first light shielding portions 410 is smaller than the distance between adjacent second light shielding portions 450.

[0059] In one embodiment, Figure 5 As shown, the display panel further includes a touch layer 43 located between the first light shielding layer 41 and the second light shielding layer 45 .

[0060] In one embodiment, Figure 5 As shown, the display panel further includes a cover plate 44 , which is located on the side of the second light shielding layer 45 away from the substrate 10 .

[0061] Figure 7 Another embodiment provides Figure 5 The cross-sectional structure diagram of the display panel along the A5A6 line is shown. Figure 7 The display panel and Figure 6 The difference between the display panels shown is that, in this embodiment, the Figure 7 and Figure 5 As shown, the sub-pixel 300 includes a first electrode 301, and the first electrode 301 is electrically connected to the pixel circuit 20. At least two anti-peeping sub-pixels 320 include a first anti-peeping sub-pixel 321 and a second anti-peeping sub-pixel 322, and the first anti-peeping sub-pixel 321 and the second anti-peeping sub-pixel 322 share the same first electrode 301. Exemplarily, the first electrode 301 includes an anode.

[0062] In one embodiment, Figure 7 As shown, the display panel further includes a pixel definition layer 48, which is located on the side of the pixel circuit 20 away from the substrate 10. The pixel definition layer 48 has a pixel opening H1, and the orthographic projection of the pixel opening H1 on the substrate 10 is located within the orthographic projection range of the first electrode 301 on the substrate 10.

[0070] According to the display panel provided in this embodiment, full-color display is achieved by using white light sub-pixels and a color filter layer 46. In this case, the display panel preparation process does not need to use a fine metal mask, so the sub-pixel layout design does not need to be limited by the distance between adjacent openings of the fine metal mask, thereby achieving the purpose of adjacent shared sub-pixels 310 and at least one anti-peeping sub-pixel 320 in the same pixel group 30. It can be seen that the display panel provided in this embodiment provides a feasible implementation method to achieve the purpose of adjacent shared sub-pixels 310 and at least one anti-peeping sub-pixel 320 in the same pixel group 30.

In this case, the cross-sectional shape of the isolation structure 47 can be T-shaped. The isolation portion 471 can be designed as an independent film layer, that is, there is no physical interface inside the isolation portion 471, and each part is composed of the same material. Alternatively, the isolation portion 471 can be designed to be composed of at least two film layers stacked. For example, the isolation portion 471 is formed by stacking two conductive film layers. The materials of the two conductive film layers can be molybdenum and aluminum, respectively, and the conductive film layer composed of molybdenum is located between the substrate 10 and the conductive film layer composed of aluminum.

[0079] In one embodiment, continue to refer to Figure 8 As shown, the display panel also includes an encapsulation layer 42, which is located between the sub-pixel 300 and the first light shielding layer 41.

It can be seen that the display panel provided in this embodiment provides another feasible implementation method to achieve the purpose of adjacent shared sub-pixels 310 and at least one anti-peeping sub-pixel 320 in the same pixel group 30.
