[0115] In summary, the display panel 10 provided in the embodiment of the present application is configured to display in the first state by configuring the anti-peeping pixel unit 12 and the display pixel unit 13 to display in the second state; the orthographic projection of the display sub-pixel 13a of the display pixel unit 13 on the substrate 11 is arranged around at least a portion of the outer contour of the orthographic projection of the corresponding anti-peeping sub-pixel 12a in the anti-peeping pixel unit 12 on the substrate 11; the orthographic projection of the first light shielding structure 14 on the substrate 11 is located between the orthographic projection of the display sub-pixel 13a on the substrate 11 and the orthographic projection of the anti-peeping sub-pixel 12a on the substrate 11; and the orthographic projection of the first light shielding structure 14 on the substrate 11 surrounds the outer contour of the orthographic projection of the anti-peeping sub-pixel 12a on the substrate 11. At least part of the contour is set, so that, on the one hand, the display panel 10 can be dynamically switched between the first state and the second state in real time, thereby realizing dynamic anti-peeping of the display panel 10, and when the display panel 10 is in the first state, the first shading structure 14 can block the large-angle light emitted by the anti-peeping sub-pixel 12a, reduce the visible viewing angle of the display panel 10 in the first state, and improve the anti-peeping effect of the display panel 10; on the other hand, the density of the distribution of the display sub-pixel 13a and the anti-peeping sub-pixel 12a can be increased, thereby increasing the opening area of ​​the display panel 10, increasing the aperture ratio of the display panel 10, and further improving the display effect of the display panel 10 in the first state and the second state.

[0116] In one embodiment, see Figures 1 to 6 , multiple display sub-pixels 13a include a first display sub-pixel 13a1, a second display sub-pixel 13a2 and a third display sub-pixel 13a3; multiple anti-peeping sub-pixels 12a include a first anti-peeping sub-pixel 12a1, a second anti-peeping sub-pixel 12a2 and a third anti-peeping sub-pixel 12a3; the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1 are configured to emit a first color light; the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2 are configured to emit a second color light; the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3 are configured to emit a third color light; the orthographic projection of the first display sub-pixel 13a1 on the substrate 11 is arranged around at least a portion of the outer contour of the orthographic projection of the first anti-peeping sub-pixel 12a1 on the substrate 11.

[0117] In this way, on the one hand, the density of the distribution of the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1 can be improved, so that the opening panel of the display panel 10 can be improved, the opening rate of the display panel 10 can be improved, and then the display effect of the display panel 10 in the first state and the second state can be improved; on the other hand, both the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1, both the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2, and both the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3 can be formed by opening evaporation of the same mask plate. In this way, the manufacturing process of the display panel 10 can be simplified and the production cost of the display panel 10 can be reduced.

[0118] In one embodiment, see Figures 1 to 6 The orthographic projection of the second display sub-pixel 13a2 on the substrate 11 is arranged around at least a portion of the outer contour of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11.

[0119] In this way, the distribution density of the second display sub-pixel 13a2 and the second anti-peep sub-pixel 12a2 can be improved, so as to further improve the opening panel of the display panel 10, further improve the aperture ratio of the display panel 10, and further improve the display effect of the display panel 10 in the first state and the second state.

[0121] In this way, the density of distribution of the third display sub-pixel 13a3 and the third anti-peep sub-pixel 12a3 can be improved, so as to further improve the opening panel of the display panel 10, further improve the aperture ratio of the display panel 10, and further improve the display effect of the display panel 10 in the first state and the second state.

[0122] In one of the embodiments, the anti-peeping pixel unit 12 is further configured to display in the second state.

[0123] That is to say, when the display panel 10 is in the second state, both the anti-peep pixel unit 12 and the display pixel unit 13 emit light. In this way, on the one hand, the viewing angle of the display panel 10 can be increased; on the other hand, the pixel density and resolution of the display panel 10 in the second state can be guaranteed, thereby improving the display effect of the display panel 10 in the second state.

[0124] In one embodiment, see Figure 1 and Figure 2, the orthographic projection of the first display sub-pixel 13a1 on the substrate 11 surrounds the outer contour of the orthographic projection of the first anti-peeping sub-pixel 12a1 on the substrate 11; and / or the orthographic projection of the second display sub-pixel 13a2 on the substrate 11 surrounds the outer contour of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11; and / or the orthographic projection of the second display sub-pixel 13a2 on the substrate 11 surrounds the outer contour of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11.

[0125] In this way, the opening area of ​​the display panel 10 can be further increased, the opening ratio of the display panel 10 can be increased, and thus the display effect of the display panel 10 can be improved; in addition, both the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1, both the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2, and both the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3 can be formed by evaporation of the opening of the same mask plate. In this way, the manufacturing process of the display panel 10 can be simplified and the production cost of the display panel 10 can be reduced.

[0128] In one embodiment, see Figure 1 and Figure 2 The orthographic projection of the second display sub-pixel 13a2 on the substrate 11 is a closed ring.

[0129] In this way, it is convenient to arrange the orthographic projection of the second display sub-pixel 13a2 on the substrate 11 around the outer contour of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11, which is beneficial to improve the distribution density between the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2, and improve the aperture ratio of the display panel 10, thereby improving the display effect of the display panel 10.

[0130] In one embodiment, see Figure 1 and Figure 2 The orthographic projection of the third display sub-pixel 13a3 on the substrate 11 is a closed ring.

[0131] In this way, it is convenient to arrange the orthographic projection of the third display sub-pixel 13a3 on the substrate 11 around the outer contour of the orthographic projection of the third anti-peeping sub-pixel 12a3 on the substrate 11, which is beneficial to improve the distribution density between the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3, improve the aperture ratio of the display panel 10, and thus improve the display effect of the display panel 10.

[0132] In one embodiment, see Figure 1 and Figure 2 , the center of the orthographic projection of the first display sub-pixel 13a1 on the substrate 11 coincides with the center of the orthographic projection of the first anti-peeping sub-pixel 12a1 on the substrate 11.

[0133] In this way, the uniformity of brightness when both the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1 are displayed in the second state can be improved, thereby improving the display effect of the display panel 10 in the second state.

[0134] In one embodiment, see Figure 1 and Figure 2 , the center of the orthographic projection of the second display sub-pixel 13a2 on the substrate 11 coincides with the center of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11.

[0135] In this way, the uniformity of brightness when the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2 are both displayed in the second state can be improved, thereby improving the display effect of the display panel 10 in the second state.

[0136] In one embodiment, see Figure 1 and Figure 2 , the center of the orthographic projection of the third display sub-pixel 13a3 on the substrate 11 coincides with the center of the orthographic projection of the third anti-peeping sub-pixel 12a3 on the substrate 11.

[0137] In this way, the uniformity of brightness when the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3 are both displayed in the second state can be improved, thereby improving the display effect of the display panel 10 in the second state.

[0138] In one embodiment, see Figure 1 and Figure 2 The first display sub-pixel 13a1 and the second display sub-pixel 13a2 are arranged adjacent to each other and are both arranged adjacent to the third display sub-pixel 13a3.

[0139] In this way, it is convenient to realize color display of the display panel 10 in the first state and the second state, thereby improving the display effect of the display panel 10 .

[0140] In one embodiment, see Figure 1 and Figure 2 The first display sub-pixel 13a1 and the second display sub-pixel 13a2 are arranged along the second direction Y, and the first display sub-pixel 13a1 and the second display sub-pixel 13a2 are both located on one side of the third display sub-pixel 13a3 along the first direction X; the first direction X intersects with the second direction Y and are both perpendicular to the thickness direction of the substrate 11.

[0141] In this way, the arrangement regularity and uniformity of the first display sub-pixel 13a1 , the second display sub-pixel 13a2 and the third display sub-pixel 13a3 can be improved, so as to facilitate the manufacture of the display panel 10 and improve the display effect of the display panel 10 .

[0142] In one embodiment, see Figure 1 and Figure 2 A first display sub-pixel 13a1, a second display sub-pixel 13a2, a third display sub-pixel 13a3, a first anti-peeping sub-pixel 12a1, a second anti-peeping sub-pixel 12a2 and a third anti-peeping sub-pixel 12a3 constitute a repeating unit, and multiple repeating units are arranged in rows along the first direction X and in columns along the second direction Y.

[0143] In this way, the arrangement of the display sub-pixels 13 a and the anti-peeping sub-pixels 12 a can be made more uniform, thereby facilitating improving the display effect of the display panel 10 .

[0144] In one embodiment, see Figures 3 to 6 , the orthographic projection of the first display sub-pixel 13a1 on the substrate 11 is arranged around a partial outer contour of the orthographic projection of the first anti-peeping sub-pixel 12a1 on the substrate 11; the orthographic projection of the second display sub-pixel 13a2 on the substrate 11 is arranged around a partial outer contour of the orthographic projection of the second anti-peeping sub-pixel 12a2 on the substrate 11; the orthographic projection of the third display sub-pixel 13a3 on the substrate 11 is arranged around a partial outer contour of the orthographic projection of the third anti-peeping sub-pixel 12a3 on the substrate 11; the first anti-peeping sub-pixel 12a1 and the second anti-peeping sub-pixel 12a2 are adjacent to each other and are both adjacent to the third anti-peeping sub-pixel 12a3.

[0145] That is to say, the first display sub-pixel 13a1 and the first anti-peeping sub-pixel 12a1 are non-concentrically arranged, the second display sub-pixel 13a2 and the second anti-peeping sub-pixel 12a2 are non-concentrically arranged, the third display sub-pixel 13a3 and the third anti-peeping sub-pixel 12a3 are non-concentrically arranged, and the first anti-peeping sub-pixel 12a1 and the second anti-peeping sub-pixel 12a2 and the third anti-peeping sub-pixel 12a3 are centrally arranged. In this way, on the one hand, the aperture ratio of the display panel 10 can be increased, thereby improving the display effect of the display panel 10. On the other hand, the white light composite effect of the display panel 10 in the first state and the second state is improved, thereby further improving the display effect of the display panel 10.

[0146] In one embodiment, see Figures 3 to 6 The orthographic projections of the first display sub-pixel 13a1, the second display sub-pixel 13a2 and the third display sub-pixel 13a3 on the substrate 11 together constitute a first figure; the orthographic projections of the first anti-peeping sub-pixel 12a1, the second anti-peeping sub-pixel 12a2 and the third anti-peeping sub-pixel 12a3 on the substrate 11 together constitute a second figure, and the first figure is arranged around the second figure.

[0147] In this way, the compactness of the arrangement of the first display sub-pixel 13a1, the second display sub-pixel 13a2, the third display sub-pixel 13a3, the first anti-peeping sub-pixel 12a1, the second anti-peeping sub-pixel 12a2 and the third anti-peeping sub-pixel 12a3 can be improved, thereby increasing the opening area of ​​the display panel 10, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0148] In one embodiment, see Figures 3 to 6 , the center of the first figure coincides with the center of the second figure.

[0149] In this way, the white light composite effect of the display panel 10 in the first state and the second state can be further improved, and the display effect of the display panel 10 can be further improved.

[0150] In one embodiment, the first figure is an axially symmetrical figure or a centrally symmetrical figure; the second figure is an axially symmetrical figure or a centrally symmetrical figure.

[0151] In one embodiment, see Figure 5 to Figure 6 , the first figure is hexagonal; the second figure is square, rectangular or circular.

[0152] In one embodiment, see Figures 3 to 6 The first anti-peeping sub-pixel 12a1 and the second anti-peeping sub-pixel 12a2 are arranged along the second direction Y, and the first anti-peeping sub-pixel 12a1 and the second anti-peeping sub-pixel 12a2 are both located on one side of the third anti-peeping sub-pixel 12a3 along the first direction X; the first direction X intersects with the second direction Y and are both perpendicular to the thickness direction of the substrate 11.

[0153] In this way, the color display of the display panel 10 in the first state can be easily realized, thereby improving the display effect of the display panel 10 .

[0154] In one embodiment, see Figures 1 to 6, a first display sub-pixel 13a1, a second display sub-pixel 13a2, a third display sub-pixel 13a3, a first anti-peeping sub-pixel 12a1, a second anti-peeping sub-pixel 12a2 and a third anti-peeping sub-pixel 12a3 constitute a repeating unit, and a plurality of repeating units are arranged in rows along the first direction X and in columns along the second direction Y;

[0155] In this way, the arrangement of the display sub-pixels 13 a and the anti-peeping sub-pixels 12 a can be made more uniform, thereby facilitating improving the display effect of the display panel 10 .

[0156] In one embodiment, see Figure 5 to Figure 6 , the repeating units in two adjacent columns are staggered.

[0157] In this way, the compactness of the arrangement of the repeating units can be further improved, thereby increasing the opening area of ​​the display panel 10 , thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10 .

[0158] In one embodiment, see Figure 7 The first light shielding structure 14 includes a plurality of first light shielding portions 141 arranged at intervals, the plurality of first light shielding portions 141 are arranged corresponding to the plurality of anti-peeping sub-pixels 12a, and the orthographic projections of the first light shielding portions 141 on the substrate 11 are arranged around the outer contours of the orthographic projections of the corresponding anti-peeping sub-pixels 12a on the substrate 11;

[0159] In this way, the first light shielding portion 141 can block large-angle light in all directions around the anti-peeping sub-pixel 12 a, which can effectively reduce the visible viewing angle of the display panel 10 in the first state, and further improve the anti-peeping effect of the display panel 10 .

[0160] In one embodiment, see Figure 7 The orthographic projection of the first light shielding portion 141 on the substrate 11 is a closed ring.

[0161] In this way, the orthographic projection of the first light shielding portion 141 on the substrate 11 can be conveniently arranged around the outer contour of the orthographic projection of the corresponding anti-peeping sub-pixel 12a on the substrate 11, thereby blocking large-angle light in all directions around the anti-peeping sub-pixel 12a, thereby improving the anti-peeping effect of the display panel 10.

[0162] In one embodiment, see Figure 7 The first light shielding portion 141 includes a plurality of first light shielding sub-portions 1411 spaced apart along a direction from the anti-peeping sub-pixel 12a to the display sub-pixel 13a, and the orthographic projections of the first light shielding sub-portions 1411 on the substrate 11 are arranged around the outer contour of the orthographic projection of the corresponding anti-peeping sub-pixel 12a on the substrate 11.

[0163] In this way, the plurality of first light shielding sub-portions 1411 can perform multiple shielding on the large-angle light of the anti-peeping sub-pixel 12 a, thereby effectively improving the anti-peeping effect of the display panel 10 .

[0164] In one embodiment, the orthographic projection of the first light shielding sub-portion 1411 on the substrate 11 is a closed ring.

[0165] In this way, the orthographic projection of the first light shielding sub-portion 1411 on the substrate 11 can be conveniently arranged around the outer contour of the orthographic projection of the corresponding anti-peeping sub-pixel 12a on the substrate 11, thereby blocking large-angle light in all directions around the anti-peeping sub-pixel 12a, thereby effectively improving the anti-peeping effect of the display panel 10.

[0166] In one embodiment, along the direction from the anti-peeping sub-pixel 12a to the corresponding display sub-pixel 13a, the heights of the plurality of first light-shielding sub-portions 1411 gradually increase; the height of the first light-shielding sub-portion 1411 is the dimension of the first light-shielding sub-portion 1411 along the thickness direction parallel to the substrate 11.

[0167] In this way, the plurality of first light shielding sub-portions 1411 can effectively shield large-angle light from all directions around the anti-peeping sub-pixel 12 a, thereby further improving the anti-peeping effect of the display panel 10 .

[0168] In one embodiment, the height of the first light shielding sub-portion 1411 is 3um to 5um. Specifically, the height of the first light shielding sub-portion 1411 can be 3um, 3.5um, 4um, 4.5um, 5um or any value in the range of 3um to 5um.

[0169] In this way, by setting the height of the first light shielding sub-portion 1411 within the above-mentioned appropriate numerical range, the production of the first light shielding sub-portion 1411 can be facilitated, and the light shielding effect of the first light shielding sub-portion 1411 can be improved, thereby facilitating the production of the display panel 10 and improving the anti-peeping effect of the display panel 10.

[0170] In one embodiment, the absolute value of the height difference between two adjacent first light shielding sub-portions 1411 is between 1 um and 2 um.

[0171] In one embodiment, see Figure 7 The cross-sectional shape of the first light-shielding sub-portion 1411 on the first plane is trapezoidal, rectangular or inverted trapezoidal; the first plane is parallel to the thickness direction of the substrate 11 , and the first plane is perpendicular to the extension direction of the first light-shielding sub-portion 1411 .

[0172] In one embodiment, the width of the first light shielding sub-portion 1411 is 2um to 6um; the width of the first light shielding sub-portion 1411 is the orthographic projection of the first light shielding sub-portion 1411 in the first plane, and is perpendicular to the extension direction of the first light shielding sub-portion 1411. Specifically, the width of the first light shielding sub-portion 1411 can be 2um, 2.5um, 3um, 3.5um, 4um, 4.5um, 5um, 5.5um, 6um or any value between 2um and 6um.

[0173] Thus, by making the width of the first light shielding sub-portion 1411 within the above-mentioned suitable range, the production of the first light shielding sub-portion 1411 can be facilitated, and the light shielding effect of the first light shielding sub-portion 1411 can be improved, thereby facilitating the production of the display panel 10 and improving the anti-peeping effect of the display panel 10.

[0174] In one embodiment, the material of the first light shielding structure 14 includes inorganic material or organic material.

[0175] In one embodiment, see Figure 7 , and also includes a pixel defining layer 15, which is arranged on one side of the substrate 11; the pixel defining layer 15 is provided with a plurality of first openings 15a and a plurality of second openings 15b, and the second openings 15b are arranged around at least part of the periphery of the corresponding first openings 15a; the anti-peeping sub-pixel 12a is at least partially arranged in the first opening 15a; the display sub-pixel 13a is at least partially arranged in the second opening 15b; the first shading structure 14 is arranged on the side of the pixel defining layer 15 away from the substrate 11, and the first shading structure 14 is in contact with the pixel defining layer 15.

[0176] In this way, on the one hand, the first light shading structure 14 can block the anti-peeping sub-pixel 12a in a large angle direction, thereby improving the anti-peeping effect of the display panel 10. On the other hand, the first light shading structure 14 can extend the path of electrical crosstalk between the anti-peeping sub-pixel 12a and the display sub-pixel 13a, thereby reducing the electrical crosstalk between the anti-peeping sub-pixel 12a and the display sub-pixel 13a and improving the display effect of the display panel 10.

[0177] In one embodiment, see Figure 7The anti-peeping sub-pixel 12a includes a first light-emitting functional portion 121, and the display sub-pixel 13a includes a second light-emitting functional portion 131. The first light-emitting functional portion 121 is arranged in the first opening 15a; the second light-emitting functional portion 131 is arranged in the second opening 15b; the first light-emitting functional portion 121 and the corresponding second light-emitting functional portion 131 are configured to emit light of the same color; the first light-emitting functional portion 121 and the second light-emitting functional portion 131 both include a light-emitting layer and a multi-layer functional film layer arranged in a stacked manner; at least one layer of the multi-layer functional film layer is extended to a side surface of the pixel defining layer 15 away from the substrate 11; the functional film layer of the first light-emitting functional portion 121 extended to the pixel defining layer 15 and the functional film layer of the corresponding second light-emitting functional portion 131 extended to the pixel defining layer 15 are disconnected from each other by means of the first shading structure 14.

[0178] In this way, the electrical crosstalk between the anti-peeping sub-pixel 12 a and the display sub-pixel 13 a can be further reduced, and the display effect of the display panel 10 can be further improved.

[0179] It is understandable that the functional film layers of the first light-emitting functional part 121 and the second light-emitting functional part 131 include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL) and an electron blocking layer (EBL). Alternatively, the first light-emitting functional part 121 and the second light-emitting functional part 131 can also be a laminated light-emitting layer, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0180] In one embodiment, see Figure 7 The anti-peeping sub-pixel 12a also includes a first electrode 122, and the display sub-pixel 13a also includes a second electrode 132. The first electrode 122 is arranged on a side of the first light-emitting functional portion 121 away from the substrate 11, and the second electrode 132 is arranged on a side of the second light-emitting functional portion 131 away from the substrate 11; the first electrode 122 and the second electrode 132 are arranged in the same layer and are connected to each other.

[0182] In one embodiment, see Figure 7 The anti-peeping sub-pixel 12a also includes a third electrode 123, and the display sub-pixel 13a also includes a fourth electrode 133; the third electrode 123 and the fourth electrode 133 are distributed at intervals and are both arranged between the pixel defining layer 15 and the substrate 11, the first opening 15a exposes the third electrode 123, and the second opening 15b exposes the fourth electrode 133.

[0183] It should be understood that both the third electrode 123 and the fourth electrode 133 may be anodes.

[0184] In one embodiment, the third electrode 123 and the fourth electrode 133 are disposed in the same layer.

[0185] In one embodiment, see Figure 8 , and also includes multiple first lens structures 16, which are arranged corresponding to multiple anti-peeping sub-pixels 12a; the first lens structure 16 is arranged on a side of the corresponding anti-peeping sub-pixel 12a away from the substrate 11; the orthographic projection of the first lens structure 16 on the substrate 11 covers the orthographic projection of the first opening 15a on the substrate 11.

[0186] In this way, the first lens structure 16 can converge the light emitted by the anti-peeping sub-pixel 12a, especially the large-angle light, so that the light emitted by the anti-peeping sub-pixel 12a is more concentrated above it, thereby improving the brightness of the anti-peeping sub-pixel 12a, extending the service life of the anti-peeping sub-pixel 12a, reducing the risk of color shift of the display panel 10, improving the display effect of the display panel 10, reducing the power consumption of the display panel 10, and extending the service life of the display panel 10.

[0187] In one embodiment, see Fig. 9 , and also includes multiple second lens structures 17, which are arranged corresponding to multiple display sub-pixels 13a, and the second lens structures 17 are arranged on the side of the corresponding display sub-pixels 13a away from the substrate; the orthographic projection of the second lens structure 17 on the substrate 11 covers the orthographic projection of the second opening 15b on the substrate 11.

[0188] In this way, the second lens structure 17 can converge the light emitted by the display sub-pixel 13a, especially the large-angle light, so that the light emitted by the sub-pixel of the display panel 10 is more concentrated above it, thereby improving the brightness of the display sub-pixel 13a, extending the service life of the display sub-pixel 13a, reducing the risk of color deviation of the display panel 10, improving the display effect of the display panel 10, reducing the power consumption of the display panel 10, and extending the service life of the display panel 10.

[0189] In one embodiment, see Figures 8 to 9, and also includes an encapsulation layer 18, which covers the anti-peeping pixel unit 12, the display pixel unit 13 and the first shading structure 14; multiple first lens structures 16 and multiple second lens structures 17 are all arranged on the side of the encapsulation layer 18 away from the substrate 11.

[0190] In this way, the anti-peeping pixel unit 12 , the display pixel unit 13 and the first light shielding structure 14 can be encapsulated by the encapsulation layer 18 , thereby improving the reliability of the display panel 10 .

[0191] In one embodiment, see Figures 8 to 9 The encapsulation layer 18 includes a plurality of inorganic encapsulation layers 181 stacked together.

[0192] In this way, the packaging effect of the display panel 10 can be improved, and the reliability of the display panel 10 can be improved.

[0193] In one embodiment, the refractive index of the inorganic encapsulation layer 181 adjacent to the first lens structure 16 and the second lens structure 17 is 1.4 to 1.6. For example, the refractive index of the inorganic encapsulation layer 181 adjacent to the first lens structure 16 and the second lens structure 17 may be 1.4, 1.42, 1.44, 1.46, 1.48, 1.50, 1.52, 1.54, 1.56, 1.58, 1.6, etc.;

[0194] In this way, when the display panel 10 is in the first state, the light emitted by the anti-peeping sub-pixel 12a passes through the inorganic encapsulation layer 181 and the first lens structure 16 in sequence and is gathered and then emitted, thereby improving the light extraction rate of the display panel 10, improving the display effect of the display panel 10 in the first state, and reducing the power consumption of the display panel 10 in the first state; when the display panel 10 is in the second state, the light emitted by the display sub-pixel 13a passes through the inorganic encapsulation layer 181 and the second lens structure 17 in sequence and is gathered and then emitted, and the light emitted by the anti-peeping sub-pixel 12a passes through the inorganic encapsulation layer 181 and the first lens structure 16 in sequence and is gathered and then emitted, thereby improving the light extraction rate of the display panel 10, improving the display effect of the display panel 10 in the second state, and reducing the power consumption of the display panel 10 in the second state.

[0195] In one embodiment, the refractive index of the first lens structure 16 is 1.5-1.7. The refractive index of the first lens structure 16 can be 1.5, 1.52, 1.54, 1.56, 1.58, 1.60, 1.62, 1.64, 1.66, 1.68, 1.7, etc.

[0196] In one embodiment, the refractive index of the second lens structure 17 is 1.5-1.7. The refractive index of the second lens structure 17 can be 1.5, 1.52, 1.54, 1.56, 1.58, 1.60, 1.62, 1.64, 1.66, 1.68, 1.7, etc.

[0197] In one embodiment, both the first lens structure 16 and the second lens structure 17 can be micro-lens structures, and the micro-lens structures can be hemispherical or non-hemispherical.

[0198] In one embodiment, see Figures 8 to 9 , further comprising a first planarization layer 19 ; the first planarization layer 19 covers the first lens structure 16 , the second lens structure 17 and the encapsulation layer 18 .

[0199] This helps to improve the flatness of the surface of the first lens structure 16 and the second lens structure 17 on the side away from the substrate 11 , and helps to ensure subsequent process manufacturing.

[0200] In one embodiment, the refractive index of the first planarization layer 19 is 1.6-1.9.

[0201] In this way, the light extraction rate of the display panel 10 in the first state and the second state can be further improved, the display effect of the display panel 10 in the first state and the second state can be improved, and the power consumption of the display panel 10 in the first state and the second state can be reduced.

[0203] In one embodiment, see Figures 8 to 9 The encapsulation layer 18 further includes an organic encapsulation layer 182 , and the organic encapsulation layer 182 is disposed between two adjacent inorganic encapsulation layers 181 .

[0204] Thus, the display panel 10 can be protected by stacking the inorganic encapsulation layer 181 and the organic encapsulation layer 182. Inorganic materials generally have good compactness and can isolate water vapor and oxygen. Organic materials have flexible characteristics. Using organic materials as a layer in the encapsulation layer 18 can buffer stress from the outside, prevent the display panel 10 from being affected by external stress and affect the display effect. At the same time, it can reduce the risk of encapsulation failure caused by the breakage of the inorganic encapsulation layer 181.

[0205] In one embodiment, the material of the inorganic encapsulation layer 181 includes at least one of silicon nitride, silicon oxide, aluminum oxide, and titanium oxide.

[0207] In one embodiment, the thickness of the first planarization layer 19 is 4 um to 6 um. Specifically, the thickness of the first planarization layer 19 may be 4 um, 4.5 um, 5 um, 5.5 um or 6 um.

[0208] In one embodiment, see Fig.10 , and also includes a second shading structure 20, which is arranged on a side of the first shading structure 14 away from the substrate 11, and the orthographic projection of the second shading structure 20 on the substrate 11 is located between the orthographic projection of the display sub-pixel 13a on the substrate 11 and the orthographic projection of the anti-peeping sub-pixel 12a on the substrate 11; and the orthographic projection of the second shading structure 20 on the substrate 11 is arranged around at least a portion of the outer contour of the orthographic projection of the anti-peeping sub-pixel 12a on the substrate 11.

[0209] In this way, the second light shielding structure 20 can shield the large-angle light of the anti-peeping sub-pixel 12 a that is not shielded by the first light shielding structure 14 , thereby further improving the anti-peeping effect of the display panel 10 .

[0210] In one embodiment, see Fig.10 , the orthographic projection of the second light-shielding structure 20 on the substrate 11 does not overlap with the orthographic projection of the first light-shielding structure 14 on the substrate 11 .

[0211] In this way, the second light shielding structure 20 can effectively shield the large-angle light of the anti-peeping sub-pixel 12 a that is not shielded by the first light shielding structure 14 , thereby further improving the anti-peeping effect of the display panel 10 .

[0212] In one embodiment, see Fig.10 , the orthographic projection of the second light-shielding structure 20 on the substrate 11 is arranged around the orthographic projection of the first light-shielding structure 14 on the substrate 11;

[0213] In this way, the second light shielding structure 20 can effectively shield the large-angle light in all directions around the anti-peeping sub-pixel 12 a that is not blocked by the first light shielding structure 14 , thereby further improving the anti-peeping effect of the display panel 10 .

[0215] In this way, the second light shielding portion 201 can shield the anti-peeping sub-pixel 12 a at a large angle in all directions around the periphery, thereby effectively improving the anti-peeping effect of the display panel 10 .

[0216] In one embodiment, see Fig.10 The second light shielding portion 201 includes a closed ring shape whose orthographic projection on the substrate 11 is formed.

[0217] In this way, the orthographic projection of the second shading portion 201 on the substrate 11 can be conveniently arranged around the outer contour of the orthographic projection of the corresponding anti-peeping sub-pixel 12a on the substrate 11, thereby blocking large-angle light in all directions around the anti-peeping sub-pixel 12a, thereby effectively improving the anti-peeping effect of the display panel 10.
