Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel, a method for preparing the display panel, and a display device having the display panel. Background Art

[0002] Organic Light Emitting Diode (OLED) is currently the mainstream display product used in smart display terminals because of its many advantages such as self-luminescence, high brightness, high contrast, high color gamut, fast response speed, wide viewing angle, low power consumption and flexible display.

[0003] At present, OLED display products need to have not only screen sharing display status, but also anti-peeping display status. When using OLED display products in public scenes, it is necessary to share screen information and put the OLED display products in screen sharing display status. When using OLED display products in scenes involving privacy, the OLED display products need to be switched to anti-peeping display status. Summary of the invention

[0004] An object of the embodiments of the present disclosure is to provide a display panel and a method for manufacturing the same, and a display device, so as to solve the problem of poor anti-peeping display effect of the display panel and the display device.

[0007] In the above display panel, the wide-angle outgoing light emitted from the second light-emitting device can enter the first light blocker and the light shielding body. The first light blocker and the light shielding body can block and absorb the wide-angle outgoing light that would otherwise be transmitted from the second light-emitting device to the outside of the display panel, and can limit the range of the outgoing angle of the second light-emitting device, thereby reducing the light-emitting angle of the display panel when it is in the anti-peeping display state, and improving the anti-peeping display effect of the display panel. In addition, the first light blocker can also prevent light of different colors emitted from other light-emitting areas from entering the light-emitting area, so as to ensure the color purity of the light emitted from each light-emitting area, improve the contrast of the color of the light emitted from each light-emitting area, and thus improve the display effect of the display panel.

[0055] Figure 1A and Figure 1B is a structural diagram of a display device with an anti-peeping function according to some embodiments. Figure 2A and Figure 2B FIG. 4 is a diagram showing an arrangement structure of sub-pixels in a display device with an anti-peeping function according to some embodiments.

[0056] like Figure 1A and Figure 1B As shown, the display device 001 with anti-peeping function includes a light-emitting device 01 for normal display and a light-emitting device 02 for anti-peeping display. When the display device 001 with anti-peeping function is used in a public scene, Figure 2A As shown, the normal display light emitting device 01 and the anti-peeping display light emitting device 02 are lit at the same time (i.e., multiple rows are lit at the same time). Figure 2A The light-emitting device in the area shown in the dotted box in the middle) can make the display device in a screen sharing display state; when using the display device 001 with an anti-peeping function in a scene involving privacy, such as Figure 2B As shown, the normal display light emitting device 01 is turned off, and only the anti-peeping display light emitting device 02 is turned on (i.e., only a plurality of lines are turned on). Figure 2B The light-emitting device in the area shown in the dotted box in the middle) can switch the display device to an anti-peeping display state.

[0057] However, the inventors of the present disclosure have discovered through research that in the display device 001 with an anti-peeping function, the wide-angle output light emitted by the light-emitting device 02 of the anti-peeping display is easily transmitted from both sides of the light-emitting device 02 of the anti-peeping display to the outside of the display device, resulting in the existing display device 001 with an anti-peeping function having a large anti-peeping angle and a poor anti-peeping effect.

[0058] Based on this, the embodiments of the present disclosure provide a display panel and a method for manufacturing the same, and a display device to overcome the above problems, which are described below.

[0059] Figure 3 is a structural diagram of a display device according to some embodiments.

[0060] See also Figure 3 , some embodiments of the present disclosure provide a display device 1000. The display device 1000 can be used to display static images or dynamic pictures. For example, the display device 1000 can be a small or medium-sized display device of a tablet computer, a smart phone, a head-mounted display, a car navigation unit, a camera, a vehicle-mounted center information display (CID), a watch-type display device or other wearable device, a personal digital assistant (PDA), a portable multimedia player (PMP) or a game console, as well as medium and large electronic devices such as televisions, external billboards, monitors, household appliances including display screens, personal computers or laptop computers. The above electronic devices can represent simple examples of application display devices, so those of ordinary skill in the art can recognize that the display device 1000 can also be other electronic devices without departing from the spirit and scope of the present disclosure.

[0061] like Figure 3 As shown, the display device 1000 may include a display panel 100 and a circuit board 200, and the display panel 100 is coupled to the circuit board 200. The circuit board 200 may be located on the backlight side of the display panel 100 (i.e., the side opposite to the display side of the display panel 100). For example, the circuit board 200 may be a flexible printed circuit board (FPC) or a printed circuit board. The circuit board 200 may provide a light emitting data signal, and the display panel 100 emits light based on the light emitting data signal provided by the circuit board 200.

[0063] See also Figure 4 and Figure 5 As shown, some embodiments of the present disclosure provide a display panel 100. The display panel 100 is a display component capable of emitting display light, and the display panel 100 can emit monochromatic light (light of a single color) or colored light. The display panel 100 can be applied to the above-mentioned display device 1000.

[0064] In some embodiments, Figure 5As shown, the display panel 100 may include a substrate 10, a light emitting unit 20, a first light blocker 30 and a light shielding body 40.

The light shielding body 40 is located on a side of the substrate 10 close to the light emitting unit 20, and the light shielding body 40 extends along a second direction Y, and the second direction Y is a direction substantially perpendicular to the substrate 10. When the wide-angle output light emitted from the light emitting device of the anti-peeping display enters the first light blocker 30 and the light shielding body 40, the first light blocker 30 and the light shielding body 40 may block and absorb the wide-angle output light.

[0065] The following are detailed descriptions of the base substrate 10 , the light emitting unit 20 , the first light blocker 30 and the light shielding body 40 in the display panel 100 .

A first sub-pixel area P1, a second sub-pixel area P2 and a third sub-pixel area P3 may be spaced apart from each other and repeatedly arranged in a direction perpendicular to the base substrate 10.

[0073] In some examples, such as Figure 7 and Figure 8 As shown, the multiple light-emitting areas EA of a pixel unit area PU may include two sub-pixel areas displaying the same color, and the two sub-pixel areas displaying the same color may be arranged adjacent to each other. For example, a pixel unit area PU includes a red sub-pixel area R, two green sub-pixel areas G, and a blue sub-pixel area B, wherein the two green sub-pixel areas G in a pixel unit area PU may be arranged adjacent to each other.

[0074] In some examples, the plurality of light-emitting areas EA of a pixel unit area PU include a first sub-pixel area P1, two second sub-pixel areas P2, and a third sub-pixel area P3. A first sub-pixel area P1, two second sub-pixel areas P2, and a third sub-pixel area P3 may be arranged spaced apart from each other and repeatedly. In this case, the non-light-emitting area FA may also be located between the two second sub-pixel areas P2.

[0075] It should be noted that the sub-pixel arrangement structure in the pixel unit area PU' of the anti-peeping display can be the same as the above Figure 6A to Figure 6C , Figure 7 and Figure 8 The sub-pixel arrangement structure in the middle pixel unit area PU is the same and will not be described again here.

For another example, the thin film transistor of at least one of the first pixel circuit S1, the second pixel circuit S2, and the third pixel circuit S3 may be located in the non-luminous area FA.

[0078] like Figure 1B As shown, a pixel unit area PU' of an anti-peeping display may include a first anti-peeping pixel circuit S1', a second anti-peeping pixel circuit S2' and a third anti-peeping pixel circuit S3'. For example, the first anti-peeping pixel circuit S1' is located in the first anti-peeping sub-pixel area P1', the second anti-peeping pixel circuit S2' is located in the second anti-peeping sub-pixel area P2', and the third anti-peeping pixel circuit S3' is located in the third anti-peeping sub-pixel area P3'.

[0080] It should be noted that the transistors used in the embodiments of the present disclosure may be thin film transistors or field effect transistors or other switching devices with the same characteristics. The transistor of at least one of the first pixel circuit S1, the second pixel circuit S2 and the third pixel circuit S3 may be a thin film transistor including polysilicon or a thin film transistor including an oxide semiconductor.

[0083] like Figure 1A As shown, in a normally displayed pixel unit area PU, the plurality of light-emitting openings may include a first light-emitting opening K1, a second light-emitting opening K2, and a third light-emitting opening K3. The first light-emitting opening K1 may be located in the first sub-pixel area P1, the second light-emitting opening K2 may be located in the second sub-pixel area P2, and the third light-emitting opening K3 may be located in the third sub-pixel area P3.

[0084] like Figure 1B As shown, in a pixel unit area PU' of an anti-peeping display, the plurality of light-emitting openings may include a first anti-peeping light-emitting opening K1', a second anti-peeping light-emitting opening K2' and a third anti-peeping light-emitting opening K3'. The first anti-peeping light-emitting opening K1' may be located in the first anti-peeping sub-pixel area P1', the second anti-peeping light-emitting opening K2' may be located in the second anti-peeping sub-pixel area P2', and the third anti-peeping light-emitting opening K3' may be located in the third anti-peeping sub-pixel area P3'.

[0085] like Figure 5 As shown, the plurality of light-emitting openings may include a first light-emitting opening K1, a first anti-peeping light-emitting opening K1' and a third light-emitting opening K3. For example, the first sub-pixel region P1 may be a red light-emitting region, and the first anti-peeping sub-pixel region P1' may also be a red light-emitting region. For another example, the first sub-pixel region P1 may be a red light-emitting region, and the first anti-peeping sub-pixel region P1' may be a green light-emitting region.

[0086] like Figure 5 As shown, the light-emitting unit 20 can be located on a side of the insulating layer INL away from the base substrate 10. The plurality of light-emitting devices respectively cover the plurality of light-emitting openings, and the plurality of light-emitting devices are respectively connected to the plurality of pixel circuits. The plurality of light-emitting devices include a plurality of first light-emitting devices 21 and a plurality of second light-emitting devices 22 located in the light-emitting area EA.

[0087] The first light-emitting device 21 can be understood as a light-emitting device for normal display, and the first light-emitting device 21 is located in the pixel unit area PU for normal display. The second light-emitting device 22 can be understood as a light-emitting device for anti-peeping display, and the second light-emitting device 22 is located in the pixel unit area PU' for anti-peeping display. The first light-emitting device 21 and the second light-emitting device 22 of the same color can be the same or different, which is not limited here.

[0088] The plurality of first light emitting devices 21 may include a first red light emitting device, a first green light emitting device and a first blue light emitting device. The plurality of second light emitting devices 22 may include a second red light emitting device, a second green light emitting device and a second blue light emitting device. For example, the first red light emitting device and the second red light emitting device may be the same or different.

[0089] In some examples, such as Figure 2A and Figure 2B As shown, the plurality of first light emitting devices 21 and the plurality of second light emitting devices 22 can be completely separated and arranged in different rows, wherein the colors of the first light emitting devices 21 and the second light emitting devices 22 in two adjacent rows can be the same.

[0090] In other examples, such as Figure 6B and Figure 6C As shown, the distance between the plurality of first light-emitting devices 21 and the plurality of second light-emitting devices 22 is relatively close, and the plurality of first light-emitting devices 21 and the plurality of second light-emitting devices 22 cannot be completely separated and arranged in different rows, and the plurality of first light-emitting devices 21 and the plurality of second light-emitting devices 22 can be arranged in the same row. The colors of the adjacent first light-emitting devices 21 and the second light-emitting devices 22 can be the same or different.

[0091] Exemplarily, the light emitting device may include an OLED, a sub-millimeter light emitting diode (Mini Light Emitting Diode, Mini LED) or a micro light emitting diode (Light Emitting Diode, Micro LED), etc., which is not limited here.

[0092] Take OLED as an example, Figure 5 As shown, the OLED light-emitting device may include an anode AE, a light-emitting functional layer EL, and a cathode CE stacked in sequence. Among them, in the first light-emitting device 21 and the second light-emitting device 22 of different colors, the anode AE ​​and the light-emitting functional layer EL may be independent of each other, and the cathode CE may be shared. In the first light-emitting device 21 and the second light-emitting device 22 of the same color, the anode AE ​​may be independent of each other, and the light-emitting functional layer EL and the cathode CE may be shared. For example, in the first red light-emitting device and the second red light-emitting device, the anode AE ​​may be independent of each other, and the light-emitting functional layer EL and the cathode CE may be shared.

[0093] Fig. 9A For display panels according to some embodiments Figure 4 The cross-sectional view formed by the line AA'. Fig. 9B For along Fig. 9A A cross-sectional view of the first light blocking body formed along line BB'. Fig. 9C For along Fig. 9A A cross-sectional view of the light-shielding body formed along line CC'.

[0094] In some embodiments, Figure 5 and Fig. 9A As shown, the display panel 100 may further include an encapsulation layer TFE. The encapsulation layer TFE may be located on a side of the light emitting unit 20 away from the base substrate 10. The encapsulation layer TFE may be a single-layer structure or a multi-layer composite structure. The encapsulation layer TFE is configured to prevent water and oxygen from penetrating into the light emitting unit 20.

[0095] In some examples, such as Fig. 9A As shown, the encapsulation layer TFE may include a first inorganic layer TFE1 , an organic layer TFE2 , and a second inorganic layer TFE3 stacked in sequence along a direction in which the light emitting unit 20 is away from the base substrate 10 .

[0096] Exemplarily, along the second direction Y, the sum of the size of the first inorganic layer TFE1, the size of the organic layer TFE2, and the size of the second inorganic layer TFE3 (i.e., the thickness of the encapsulation layer TFE) is greater than or equal to 5μm and less than or equal to 25μm (for example, 5μm, 8μm, 10μm, 12μm, 15μm, 17μm, 20μm, 22μm or 25μm).

[0097] Exemplarily, the materials of the first inorganic layer TFE1 and the second inorganic layer TFE3 can be selected from at least one of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, silicon oxynitride or lithium fluoride. The material of the organic layer TFE2 can be at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane resin, cellulose resin or dinaphthylene resin. Those skilled in the art can change the number of layers, materials and structures of the thin film encapsulation layer TFE as needed, and the present disclosure is not limited thereto.

[0098] like Figure 5 , Fig. 9A and Fig. 9B As shown, the first photoresistor 30 may be located on a side of the encapsulation layer TFE away from the base substrate 10 , and the first photoresistor 30 is disposed along the first direction X in the non-light emitting area FA.

[0099] Exemplarily, the material of the first light blocking body 30 may include a black matrix material or other black light shielding materials.

[0100] The wide-angle light emitted from the second light emitting device 22 can enter the first light blocker 30, and the first light blocker 30 can block and absorb the wide-angle light that would otherwise be emitted from the second light emitting device 22. In addition, the first light blocker 30 can prevent light of different colors emitted from other light emitting areas EA from entering the light emitting area EA, so as to ensure the color purity of the light emitted from each light emitting area EA, improve the contrast of the color of the light emitted from each light emitting area EA, and thus improve the display effect of the display panel 100.

[0101] like Figure 5 , Fig. 9A and Fig. 9C As shown, the light shielding body 40 is at least located on a side of the first light blocker 30 away from the base substrate 10, and the light shielding body 40 extends in the non-luminous area FA along the second direction Y. It can be understood that in the non-luminous area FA, the light shielding body 40 can extend along the second direction Y to the side of the first light blocker 30 away from the base substrate 10, and / or the light shielding body 40 can extend along the second direction Y to the side of the first light blocker 30 close to the base substrate 10.

[0102] Exemplarily, in the non-luminous area FA, when the light-shielding body 40 is located on one side of the first photoblocker 30, the light-shielding body 40 can extend along the second direction Y to the side of the first photoblocker 30 away from the base substrate 10, or the light-shielding body 40 can extend along the second direction Y to the side of the first photoblocker 30 close to the base substrate 10.

[0103] Exemplarily, in the non-luminous area FA, when the light-shielding body 40 is located on both sides of the first photoblocking body 30, the light-shielding body 40 can extend along the second direction Y to the side of the first photoblocking body 30 away from the base substrate 10, and the light-shielding body 40 can also extend along the second direction Y to the side of the first photoblocking body 30 close to the base substrate 10.

[0104] The light shielding body 40 may be disposed on at least one side of the second light emitting device 22 along the first direction X. It can be understood that the light shielding body 40 may be disposed on one side of the second light emitting device 22 , or the light shielding body 40 may be disposed on both sides of the second light emitting device 22 .

[0105] The wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40, which can block and absorb the wide-angle output light that would otherwise be transmitted from at least one side of the second light-emitting device 22 to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, and improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0106] Exemplarily, the material of the light shielding body 40 may include a black matrix material or other black light shielding materials, which is not limited in the present disclosure.

[0107] Figure 10 to Figure 13A The display panel according to some embodiments is respectively Figure 4 The cross-sectional view formed by the line AA'. Fig. 13B For along Fig.13A A cross-sectional view of the light-shielding body formed along line DD'. Figures 14 to 18A The display panel according to some embodiments is respectively Figure 4 The cross-sectional view formed by the line AA'. Fig.18B For along Fig.18A A cross-sectional view of the light-shielding body formed along line EE'.

[0108] In some embodiments, when the light shielding body 40 is located on one side of the first light blocking body 30, as shown in FIG. Figure 5 , Fig. 9A , Fig.13A and Fig.18A As shown, the light shielding body 40 may be located on a side of the first light blocking body 30 away from the base substrate 10 .

[0109] In some examples, such as Figure 5 , Fig. 9A , Fig.13A and Fig.18A As shown, the display panel 100 may further include a planar layer 50 . The planar layer 50 is located on a side of the first light blocker 30 away from the base substrate 10 , and extends along the first direction X. The light shielding body 40 may extend along the second direction Y from the first light blocker 30 into the planar layer 50 .

[0110] By way of example, the material of the planar layer 50 may include polyimide or the like.

[0111] The wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40 in the flat layer 50. The light-shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted through the flat layer 50 to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0112] In some embodiments, Figure 10 to Figure 12 and Figure 14 to Figure 17 As shown, the light shielding body 40 may extend along the second direction Y to a side of the first light blocking body 30 close to the base substrate 10 .

[0113] In some examples, when the light-shielding body 40 is located at one side of the first light blocker 30 , the light-shielding body 40 may extend along the second direction Y from the first light blocker 30 into the encapsulation layer TFE.

[0114] In some other examples, the light shielding body 40 is located on both sides of the first light blocking body 30, such as Fig.10 and Fig.14 As shown, the light-shielding body 40 may extend along the second direction Y from the planar layer 50 into the encapsulation layer TFE.

[0115] For example, the light shielding body 40 may extend from the flat layer 50 to the second inorganic layer TFE3 of the encapsulation layer TFE along the second direction Y. For another example, the light shielding body 40 may extend from the flat layer 50 to the second inorganic layer TFE3 and the organic layer TFE2 of the encapsulation layer TFE along the second direction Y. For another example, the light shielding body 40 may extend from the flat layer 50 to the entire encapsulation layer TFE along the second direction Y.

[0116] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light shielding body 40 in the encapsulation layer TFE. The light shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted through the encapsulation layer TFE to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0117] In some examples, when the light shielding body 40 is located on one side of the first photoblocker 30 , the pixel defining layer PDL may be made of a semi-transmissive material, and the light shielding body 40 may extend along the second direction Y from the first photoblocker 30 into the pixel defining layer PDL.

[0118] In some other examples, when the light shielding body 40 is located on both sides of the first light blocking body 30, the pixel defining layer PDL may be made of a semi-transparent material, such as Fig.11 , Fig.15 and Fig.17 As shown, the light-shielding body 40 may extend along the second direction Y from the planar layer 50 into the pixel defining layer PDL.

[0119] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40 in the pixel defining layer PDL. The light-shielding body 40 in the pixel defining layer PDL can completely block and absorb the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0120] In some examples, when the light shielding body 40 is located on one side of the first photoblocker 30 , the pixel defining layer PDL can be made of black light shielding material, and the light shielding body 40 can extend along the second direction Y from the first photoblocker 30 to the surface of the pixel defining layer PDL away from the base substrate 10 .

[0121] In some other examples, when the light shielding body 40 is located on both sides of the first light blocking body 30, the pixel defining layer PDL may be made of a black light shielding material, such as Fig.12 and Fig.16 As shown, the light shielding body 40 may also extend along the second direction Y from the planar layer 50 to the surface of the pixel defining layer PDL away from the base substrate 10 .

[0122] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the pixel defining layer PDL and the light-shielding body 40. The pixel defining layer PDL and the light-shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0123] In some embodiments, Fig. 9A , Fig. 9C , Fig.13A and Fig. 13B As shown, the light shield 40 is at least disposed between the first light emitting device 21 and the second light emitting device 22. It can be understood that the light shield 40 can be disposed between the first light emitting device 21 and the second light emitting device 22; and / or, the light shield 40 can be disposed between two adjacent second light emitting devices 22 of different colors.

[0124] For example, in the case where the light-shielding body 40 is disposed on one side of the second light-emitting device 22 , the light-shielding body 40 may be disposed between the first light-emitting device 21 and the second light-emitting device 22 .

[0125] Exemplarily, when the light shielding body 40 is disposed on both sides of the second light emitting device 22, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22, and the light shielding body 40 may be disposed between two adjacent second light emitting devices 22 of different colors.

[0126] In this way, when the wide-angle output light emitted from the second light-emitting device 22 enters the light-shielding body 40, the light-shielding body 40 can at least block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 to the outside of the display device 1000, and can limit the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0127] In some examples, such as Fig. 9C and Fig. 13B As shown, the light shielding body 40 is at least disposed between the first light emitting device 21 and the second light emitting device 22 which are of the same color and adjacent to each other.

[0128] For example, when the light shielding body 40 is disposed on one side of the second light emitting device 22, Figure 5 , Fig.13A and Figures 14 to 18A As shown, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22 which are of the same color and adjacent to each other.

[0129] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40, and the light-shielding body 40 can at least block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of the same color and adjacent to each other to the outside of the display device 1000, and can limit the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0130] For example, Fig. 9C As shown, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22 that are different in color and adjacent to each other.

[0131] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40, and the light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of different colors and adjacent to each other to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0132] For example, when the light shielding body 40 is disposed on both sides of the second light emitting device 22, Fig. 9A and Figure 10 to Figure 12As shown, the light shielding body 40 includes a first light shielding body 41 and a second light shielding body 42 respectively located on both sides of the second light emitting device 22. The first light shielding body 41 is arranged between the first light emitting device 21 and the second light emitting device 22 of the same color and adjacent to each other, and the second light shielding body 42 is arranged between the first light emitting device 21 and the second light emitting device 22 of different colors and adjacent to each other.

[0133] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the first light-shielding body 41 and the second light-shielding body 42. The first light-shielding body 41 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of the same color and adjacent to each other to the outside of the display device 1000. The second light-shielding body 42 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of different colors and adjacent to each other to the outside of the display device 1000. The output angle range of the second light-emitting device 22 can be greatly limited, thereby greatly reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby greatly improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0134] In some examples, such as Fig. 13B As shown, a light shielding body 40 may be disposed between the plurality of first light emitting devices 21 and the plurality of second light emitting devices 22 .

[0135] The plurality of first light emitting devices 21 may be located on one side of the light shielding body 40, and the plurality of second light emitting devices 22 may be located on the other side of the light shielding body 40. Alternatively, a portion of the plurality of first light emitting devices 21 and a portion of the second light emitting devices 22 are located on one side of the light shielding body 40, and another portion of the plurality of first light emitting devices 21 and another portion of the second light emitting devices 22 are located on the other side of the light shielding body 40.

[0136] In this way, the wide-angle output light emitted from the multiple second light-emitting devices 22 can enter a light-shielding body 40. A light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the multiple first light-emitting devices 21 and the multiple second light-emitting devices 22 to the outside of the display device 1000. A light-shielding body 40 can limit the output angle range of the multiple second light-emitting devices 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0137] In some examples, such as Fig. 9C , Fig. 13B and Fig.18BAs shown, a light shielding body 40 may be disposed between two adjacent second light emitting devices 22 of different colors.

[0138] In this way, the wide-angle output light emitted from two second light-emitting devices 22 that are adjacent to each other and have different colors can enter a light-shielding body 40. A light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the two second light-emitting devices 22 that are adjacent to each other and have different colors to the outside of the display device 1000. A light-shielding body 40 can limit the output angle range of the two second light-emitting devices 22 that are adjacent to each other and have different colors, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0139] In some embodiments, Fig. 9C As shown, in the first direction X, the distance d between the light shading body 40 and the side wall of the second light emitting device 22 adjacent to the light shading body 40 is less than or equal to 5μm, for example, d can be 0μm, 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm or 5μm.

[0140] By limiting the distance d between the light shield 40 and the side wall of the second light emitting device 22 and adjacent to the light shield 40 within a smaller range, most of the wide-angle output light emitted from the second light emitting device 22 can enter the light shield 40. The light shield 40 can block and absorb most of the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, and can limit the output angle range of the second light emitting device 22, thereby reducing the light emission angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0141] In some embodiments, Fig. 9C As shown, the extension direction of a light shield 40 is substantially parallel to one side of the second light emitting device 22. The extension length L1 of the light shield 40 is greater than or equal to the length L2 of one side of the second light emitting device 22. It can be understood that along the first direction X, the length L1 of the light shield 40 is greater than or equal to the length L2 of one side of the second light emitting device 22.

[0142] In this way, the wide-angle output light emitted from the second light-emitting device 22 enters the light-shielding body 40. The light-shielding body 40 can block and absorb all the wide-angle output light that would originally be transmitted from the side of the second light-emitting device 22 parallel to the light-shielding body 40 to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0143] The light shielding body 40 can be an integrated structure or a split structure. Other designs of the specific shape of the light shielding body 40 made by those skilled in the art based on the embodiments of the present disclosure are within the scope of protection of the present disclosure.

[0144] In some embodiments, Fig.13A , Fig. 13B and Figure 14 to Figure 16 As shown, the light-shielding body 40 may include a plurality of sub-light-shielding bodies 43 , and the plurality of sub-light-shielding bodies 43 are sequentially arranged along the second direction Y at intervals.

[0145] For example, the cross-sectional shape of the sub-light-shielding body 43 along the first direction X may include a rectangle, a trapezoid, a circle, an ellipse, a polygon, and the like.

[0146] For example, Fig.13A As shown, along the second direction Y, the size d1 of the sub-light-shielding body 43 (i.e., the thickness of the sub-light-shielding body 43) can be greater than or equal to 1μm and less than or equal to 5μm. For example, the thickness d1 of the sub-light-shielding body 43 can be 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm or 5μm.

[0147] In this way, the wide-angle outgoing light emitted from the second light-emitting device 22 can enter the multiple sub-light shields 43, and the multiple sub-light shields 43 can block and absorb the wide-angle outgoing light that would otherwise be transmitted to the outside of the display device 1000, and can limit the range of the outgoing angle of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state. Improve the anti-peeping display effect of the display panel 100 and the display device 1000. On the basis of improving the anti-peeping display effect of the display panel 100 and the display device 1000, the multiple sub-light shields 43 can also reduce the blocking and absorption of the display light emitted from the first light-emitting device 21, thereby ensuring the screen sharing display effect of the display panel 100 and the display device 1000.

[0148] In some examples, such as Fig.13AAs shown, along the second direction Y, the spacing d2 between two adjacent sub-light shielding bodies 43 may be greater than or equal to 1.5 μm and less than or equal to 15 μm. For example, the spacing d2 between two adjacent sub-light shielding bodies 43 may be 1.5 μm, 2 μm, 3 μm, 5 μm, 7 μm, 8 μm, 9 μm, 10 μm, 12 μm, 14 μm or 15 μm. The spacing d2 between two adjacent sub-light shielding bodies 43 may be the same as or different from the thickness d1 of a sub-light shielding body 43, which is not limited here.

[0149] On the basis that multiple sub-light-shielding bodies 43 can improve the anti-peeping display effect of the display panel 100 and the display device 1000, by limiting the distance d2 between two adjacent sub-light-shielding bodies 43 within a suitable range, the shielding and absorption of the display light emitted from the first light-emitting device 21 by the multiple sub-light-shielding bodies 43 can be greatly reduced, thereby better ensuring the screen sharing display effect of the display panel 100 and the display device 1000.

[0150] In some examples, such as Fig.13A and Figure 14 to Figure 16 As shown, the plurality of sub-light shielding bodies 43 may extend from the first light blocking body 30 to the flat layer 50 along the second direction Y. The flat layer 50 may include a plurality of sub-flat layers (not shown in the figure), and the plurality of sub-flat layers and the plurality of sub-light shielding bodies 43 are alternately stacked in sequence along the second direction Y.

[0151] Exemplarily, the thickness d1 of the sub-light-shielding body 43 and the dimension of the sub-planar layer along the second direction Y (ie, the thickness of the sub-planar layer) may be the same as or different from each other, which is not limited herein.

[0152] In this way, the multiple sub-light-shielding bodies 43 can block and absorb the wide-angle outgoing light that would otherwise be transmitted through the flat layer 50 to the outside of the display device 1000, thereby limiting the emission angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0153] In some examples, such as Fig.14 As shown, the plurality of sub-light-shielding bodies 43 may extend from the flat layer 50 to the encapsulation layer TFE along the second direction Y. For example, the plurality of sub-light-shielding bodies 43 may extend from the flat layer 50 to the second inorganic layer TFE3 of the encapsulation layer TFE along the second direction Y. For another example, the plurality of sub-light-shielding bodies 43 may extend from the flat layer 50 to the second inorganic layer TFE3 and the organic layer TFE2 of the encapsulation layer TFE along the second direction Y. For another example, the plurality of sub-light-shielding bodies 43 may extend from the flat layer 50 to the entire encapsulation layer TFE along the second direction Y.

[0154] In this way, the multiple sub-light-shielding bodies 43 can block and absorb the wide-angle outgoing light that would otherwise be transmitted through the flat layer 50 and the encapsulation layer TFE to the outside of the display device 1000, thereby limiting the emission angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0155] In some examples, such as Fig.15 As shown, the plurality of sub-light-shielding bodies 43 may extend along the second direction Y from the planar layer 50 into the pixel defining layer PDL.

[0156] In this way, the multiple sub-light-shielding bodies 43 in the flat layer 50 and the multiple sub-light-shielding bodies 43 in the pixel defining layer PDL can block and absorb the wide-angle outgoing light that would otherwise be transmitted to the outside of the display device 1000, and can limit the emission angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0157] In some examples, such as Fig.16 As shown, the pixel defining layer PDL may be made of a black light shielding material, and a plurality of sub-light shielding bodies 43 may extend along the second direction Y from the planar layer 50 to a surface of the pixel defining layer PDL away from the base substrate 10 .

[0158] In this way, the multiple sub-light-shielding bodies 43 and the pixel defining layer PDL in the flat layer 50 can block and absorb the wide-angle outgoing light that would otherwise be transmitted to the outside of the display device 1000, and can limit the emission angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0159] In some embodiments, Fig.13A and Figures 14 to 18A As shown, the display panel 100 may further include a second light blocker 60. The second light blocker 60 may be located on a side of the first light blocker 30 away from the base substrate 10. The orthographic projection of the second light blocker 60 on the base substrate 10 is connected to the orthographic projection of the light shielding body 40 on the base substrate 10.

[0160] For example, Fig.13A and Figures 14 to 18A As shown, the second photoresistor 60 may be located on a surface of the planar layer 50 away from the base substrate 10 .

[0161] Exemplarily, the dimension of the second photoresistor 60 along the second direction Y (i.e., the thickness of the second photoresistor 60) may be greater than or equal to 2 μm and less than or equal to 6 μm (e.g., 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, or 6 μm).

[0162] The material of the second light blocker 60 may include a black matrix material or other black light shielding materials. The material of the second light blocker 60 may be the same as or different from the material of the first light blocker 30, which is not limited here.

[0163] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the second photoblocker 60. The second photoblocker 60, in combination with the first photoblocker 30 and the light-shielding body 40, can block and absorb the wide-angle output light transmitted to the outside of the display device 1000 from other areas except the light-emitting area EA where the second light-emitting device 22 is located. The output angle range of the second light-emitting device 22 can be limited as much as possible, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0164] In some examples, such as Fig.17 As shown, the second light blocking body 60 and the light shielding body 40 may be disposed on the same side of the second light emitting device 22 along the first direction X.

[0165] The wide-angle output light emitted from the second light-emitting device 22 can enter the second light blocker 60 and the light shielding body 40. The second light blocker 60 and the light shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted from one side of the second light-emitting device 22 to the outside of the display device 1000. The output angle range of the second light-emitting device 22 can be limited, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0166] In other examples, such as Fig.18A As shown, the second light blocker 60 may be disposed on one side of the second light emitting device 22 along the first direction X, and the light shielding body 40 may be disposed on the other side of the same second light emitting device 22 along the first direction X.

[0167] The wide-angle output light emitted from the second light-emitting device 22 can enter the second light blocker 60 and the light shielding body 40. The second light blocker 60 can block and absorb the wide-angle output light that would originally be transmitted from one side of the second light-emitting device 22 to the outside of the display device 1000. The light shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from the other side of the second light-emitting device 22 to the outside of the display device 1000. The output angle range of the second light-emitting device 22 can be greatly limited, thereby greatly reducing the light emission angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby greatly improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0168] In some examples, such as Fig.13A and Figures 14 to 18A As shown, the orthographic projection of the second photoresistor 60 on the base substrate 10 partially overlaps with the orthographic projection of the second light emitting device 22 adjacent to the second photoresistor 60 on the base substrate 10. The orthographic projection of the first photoresistor 30 in the same non-luminous area FA as the second photoresistor 60 on the base substrate 10 does not overlap with the orthographic projection of the same second light emitting device 22 on the base substrate 10. It can be understood that the second photoresistor 60 is not only located in the non-luminous area FA, but also partially extends into the luminous area EA where the adjacent second light emitting device 22 is located. The first photoresistor 30 in the same non-luminous area FA as the second photoresistor 60 is only located in the non-luminous area FA.

[0169] Exemplarily, along the first direction X, the size of the second photoresistor 60 is larger than the size of the first photoresistor 30 in the same non-luminous area FA as the second photoresistor 60, and the difference between the size of the second photoresistor 60 and the size of the first photoresistor 30 in the same non-luminous area FA is greater than or equal to 2 μm and less than or equal to 8 μm (for example, 2 μm, 2.5 μm, 3 μm, 4 μm, 4.5 μm, 5 μm, 6 μm, 7 μm, or 8 μm).

[0170] The orthographic projection of the second photoresistor 60 on the base substrate 10 may cover the orthographic projection of the first photoresistor 30 on the base substrate 10 in the same non-luminescent area FA as the second photoresistor 60 .

[0171] In this way, the second light blocker 60 can block and absorb more light emitted from the second light emitting device 22 and transmitted to the outside of the display device 1000 with a large viewing angle, and can further limit the emission angle range of the second light emitting device 22, thereby making the light emitting angle of the display panel 100 and the display device 1000 smaller when in the anti-peeping display state, and further improving the anti-peeping display effect of the display panel 100 and the display device 1000. On the basis of improving the anti-peeping display effect of the display panel 100 and the display device 1000, the first light blocker 30 will not block the normal display light emitted from the light emitting area EA where the second light emitting device 22 is located, and can ensure the display effect of the second light emitting device 22, thereby ensuring the display effect of the display panel 100 and the display device 1000.

[0172] In some embodiments, Figure 5 , Fig. 9A , Figure 10 to Figure 13A and Figures 14 to 18A As shown, the display panel 100 may further include a color filter film 70. The color filter film 70 may be located on a side of the light emitting unit 20 away from the base substrate 10. The color filter film 70 may include a first color filter film 71 and a second color filter film 72.

[0173] The first color filter film 71 covers the first light emitting device 21, and the second color filter film 72 covers the second light emitting device 22. It can be understood that the orthographic projection of the first color filter film 71 on the base substrate 10 covers the orthographic projection of the first light emitting device 21 on the base substrate 10; the orthographic projection of the second color filter film 72 on the base substrate 10 covers the orthographic projection of the second light emitting device 22 on the base substrate 10.

[0174] In the first direction X, the size of the first color filter film 71 is larger than the size of the first light emitting device 21, and the size of the second color filter film 72 is substantially equal to the size of the second light emitting device 22. It can be understood that in the first direction X, when the size of the first light emitting device 21 is the same as the size of the second light emitting device 22, the size of the first color filter film 71 is larger than the size of the second color filter film 72.

[0175] The color filter film 70 can reduce the reflection of the display light emitted by the light-emitting device, filter out the noise in the display light, improve the light extraction efficiency of the display panel 100 and the saturation of the display light, thereby improving the display effect of the display device 1000. By limiting the size of the first color filter film 71 to be larger than the size of the first light-emitting device 21, the light extraction efficiency of the first light-emitting device 21 can be improved, thereby improving the display effect of the display device 1000 in the screen sharing display state. By limiting the size of the second color filter film 72 to be approximately equal to the size of the second light-emitting device 22, the light extraction efficiency of the second light-emitting device 22 can be improved on the basis of ensuring that the emission angle range of the second light-emitting device 22 is small, thereby improving the display effect of the display device 1000 in the anti-peeping display state.

[0176] In some examples, such as Figure 5 , Fig. 9A , Figure 10 to Figure 13A and Figures 14 to 18A As shown, the color filter film 70 can be disposed in the same layer as the first light blocker 30. It can be understood that the orthographic projection of the color filter film 70 on the plane perpendicular to the base substrate 10 can at least partially overlap with the orthographic projection of the first light blocker 30 on the plane perpendicular to the base substrate 10.

[0177] In this way, the display device 1000 can be thinned while improving the display effect of the display device 1000 .

[0178] In some examples, the display panel 100 may further include a touch layer (not shown in the figure) located in the non-luminous area FA. The touch layer may be located on the side of the encapsulation layer TFE away from the base substrate 10. The touch layer may include a single metal layer or multiple metal layers. The metal layer in the touch layer may be located on the side of the encapsulation layer TFE close to the first photoresist 30. The metal layer in the touch layer may be arranged in the same layer as the color filter film 70. It can be understood that the orthographic projection of the metal layer in the touch layer on the plane perpendicular to the base substrate 10 may at least partially overlap with the orthographic projection of the color filter film 70 on the plane perpendicular to the base substrate 10.

[0179] In this way, on the basis of improving the display effect of the display device 1000 with a touch function, the display device 1000 with a touch function can be thinned.

[0180] It should be noted that, in the display panel 100 and the display device 1000 provided in the embodiments of the present disclosure, a transparent adhesive layer (Optically Clear Adhesive, OCA) may be respectively arranged between the encapsulation layer TFE and the touch layer, between the first photoresist 30 and the flat layer 50, between the surface of the flat layer 50 away from the base substrate 10 and between other adjacent functional layers, which is not limited here.

[0181] For example, Fig.18A As shown, the transparent adhesive layer may include a first transparent adhesive layer OC1, a second transparent adhesive layer OC2 and a third transparent adhesive layer OC3. The first transparent adhesive layer OC1 may be disposed between the encapsulation layer TFE and the touch layer, and the size of the first adhesive layer OC1 along the second direction Y may be greater than or equal to 2 μm and less than or equal to 6 μm (e.g., 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, or 6 μm). The second transparent adhesive layer OC2 may be disposed between the color filter film 70 and the flat layer 50, and the size of the second adhesive layer OC2 along the second direction Y may be greater than or equal to 3 μm and less than or equal to 8 μm (e.g., 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, 6 μm, 7 μm or 8 μm). The third transparent adhesive layer OC3 may be disposed on the surface of the flat layer 50 away from the base substrate 10, and the size of the third transparent adhesive layer OC3 along the second direction Y may be set according to actual needs.

[0182] In summary, in the display panel 100 and the display device 1000 provided by the embodiment of the present disclosure, the wide-angle outgoing light emitted from the second light-emitting device 22 can enter the first light blocker 30 and the light shielding body 40, and the first light blocker 30 and the light shielding body 40 can block and absorb the wide-angle outgoing light that would otherwise be transmitted from the second light-emitting device 22 to the outside of the display device 1000, and can limit the range of the outgoing angle of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, and improving the anti-peeping display effect of the display panel 100 and the display device 1000. In addition, the first light blocker 30 can also prevent light of different colors emitted from other light-emitting areas EA from entering the light-emitting area EA, so as to ensure the color purity of the light emitted from each light-emitting area EA, and improve the contrast of the color of the light emitted from each light-emitting area EA, thereby improving the display effect of the display panel 100 and the display device 1000.

[0183] Figure 19 to Figure 23 They are respectively flow charts of methods for preparing a display panel according to some embodiments.

[0184] like Fig.19 As shown, the embodiment of the present disclosure further provides a method for preparing a display panel 100 , and the method may include steps S100 to S400 .

[0185] Step S100: Provide a base substrate 10; the base substrate 10 includes a light emitting area EA and a non-light emitting area FA except the light emitting area EA. The structural features of the base substrate 10 have been described in detail above and will not be repeated here.

[0186] The substrate 10 may be a rigid substrate 10 or a flexible substrate 10. For example, the material of the substrate 10 may be polyethylene terephthalate (PET), polyimide (PI), cycloolefin polymer (COP), etc.

[0187] Exemplarily, in the Mini LED display substrate, the base substrate 10 may be a glass substrate or a printed circuit board (PCB) substrate.

[0188] After step S100, the following steps may include: forming a plurality of pixel circuits on the base substrate 10. The specific introduction of the plurality of pixel circuits has been described in detail before, and will not be repeated here.

[0189] After forming a plurality of pixel circuits, an insulating layer INL covering the plurality of pixel circuits may be formed. The specific introduction of the insulating layer INL has been described in detail before, and will not be repeated here.

[0190] Step S200 : forming a light emitting unit 20 on one side of the base substrate 10 .

[0191] like Figure 5 As shown, the light-emitting unit 20 includes a plurality of light-emitting devices. The plurality of light-emitting devices respectively cover a plurality of light-emitting openings, and the plurality of light-emitting devices are respectively connected to a plurality of pixel circuits. The plurality of light-emitting devices may include a plurality of first light-emitting devices 21 and a plurality of second light-emitting devices 22 located in the light-emitting area EA.

[0192] The first light emitting device 21 can be understood as a light emitting device for normal display, and the second light emitting device 22 can be understood as a light emitting device for anti-peeping display. The first light emitting device 21 and the second light emitting device 22 of the same color can be the same or different, which is not limited here.

[0193] Exemplarily, the light emitting device may include an OLED, a sub-millimeter light emitting diode (Mini Light Emitting Diode, Mini LED) or a micro light emitting diode (Light Emitting Diode, Micro LED), etc., which is not limited here.

[0194] Take OLED as an example, Figure 5As shown, the OLED light-emitting device may include an anode AE, a light-emitting functional layer EL and a cathode CE stacked in sequence. Step S200 may include: forming the anode AE ​​on the side of the insulating layer INL away from the substrate 10 by deposition, exposure, development and etching processes. Afterwards, forming a pixel defining layer PDL on the side of the anode away from the substrate 10; the pixel defining layer PDL is provided with a plurality of light-emitting openings, and the light-emitting openings expose the anode AE. Afterwards, forming a light-emitting functional layer EL covering the light-emitting openings. Finally, forming a cathode CE on the side of the light-emitting functional layer EL away from the anode AE.

[0195] Among them, in the first light-emitting device 21 and the second light-emitting device 22 of different colors, the anode AE ​​and the light-emitting functional layer EL can be independent of each other, and the cathode CE can be shared. In the first light-emitting device 21 and the second light-emitting device 22 of the same color, the anode AE ​​can be independent of each other, and the light-emitting functional layer EL and the cathode CE can be shared. For example, in the first red light-emitting device and the second red light-emitting device, the anode AE ​​can be independent of each other, and the light-emitting functional layer EL and the cathode CE can be shared.

[0196] In some examples, such as Figure 5 and Fig. 9A As shown, the display panel 100 may further include an encapsulation layer TFE. The encapsulation layer TFE may be a single-layer structure or a multi-layer composite structure. The structural features and materials of the encapsulation layer TFE have been described in detail above and will not be repeated here.

[0197] Exemplarily, the encapsulation layer TFE may include a first inorganic layer TFE1, an organic layer TFE2, and a second inorganic layer TFE3 stacked in sequence along a direction in which the light-emitting unit 20 is away from the base substrate 10. After step S200, the following may be performed: on a side of the light-emitting unit 20 away from the base substrate 10, the first inorganic layer TFE1 is formed by a deposition process. Then, on a side of the first inorganic layer TFE1 away from the base substrate 10, the organic layer TFE2 is formed by a deposition process. Then, on a side of the organic layer TFE2 away from the first inorganic layer TFE1, the second inorganic layer TFE3 is formed by a deposition process.

[0198] Step S300 : forming a first light blocker 30 on a side of the light emitting unit 20 away from the base substrate 10 . The first light blocker 30 is disposed in the non-light emitting area FA along a first direction X, and the first direction X is a direction parallel to the base substrate 10 .

[0199] In some examples, such as Figure 5 , Fig. 9A and Fig.10As shown, step S300 may include: forming a first photoresist material layer by coating on a side of the encapsulation layer TFE away from the base substrate 10. Then, removing the first photoresist material layer in the light-emitting area EA by exposure and development process, and retaining the first photoresist material layer in the non-light-emitting area FA as the first photoresist body 30.

[0200] Exemplarily, the material of the first light blocking body 30 may include a black matrix material or other black light shielding materials.

[0201] The wide-angle light emitted from the second light emitting device 22 can enter the first light blocker 30, and the first light blocker 30 can block and absorb the wide-angle light that would otherwise be emitted from the second light emitting device 22. In addition, the first light blocker 30 can prevent light of different colors emitted from other light emitting areas EA from entering the light emitting area EA, so as to ensure the color purity of the light emitted from each light emitting area EA, improve the contrast of the color of the light emitted from each light emitting area EA, and thus improve the display effect of the display panel 100.

[0202] Step S400: forming a light shielding body 40 on a side of the first light blocking body 30 away from the base substrate 10. The light shielding body 40 is at least disposed between the first light emitting device 21 and the second light emitting device 22, and extends in the non-light emitting area FA along the second direction Y. The second direction Y is a direction perpendicular to the base substrate 10.

[0203] Exemplarily, the material of the light shielding body 40 may be a black matrix material or other black light shielding materials, which is not limited in the present disclosure.

[0204] In some embodiments, Figure 5 , Fig. 9A , Fig.13A and Fig.18A As shown, the light shielding body 40 may be located on a side of the first light blocking body 30 away from the base substrate 10 .

[0205] The display panel 100 may further include a planar layer 50 . The planar layer 50 is located on a side of the first light blocker 30 away from the base substrate 10 , and extends along the first direction X. The light shielding body 40 may extend along the second direction Y from the first light blocker 30 into the planar layer 50 .

[0206] Along the second direction Y, the light shielding body 40 may be an integrated structure formed by a single patterning process. Fig.18A and Fig. 20 As shown, step S400 may include steps S410 to S412.

[0207] Step S410 : forming a planarization layer 50 on a side of the first photoresist 30 away from the base substrate 10 .

[0208] For example, step S410 may include: forming a planar layer 50 on a side of the first photoresist 30 away from the base substrate 10 by inkjet printing and curing.

[0209] Step S411 : forming at least one first through hole 45 extending along the second direction Y in the planar layer 50 . The first through hole 45 is at least disposed between the first light emitting device 21 and the second light emitting device 22 .

[0210] For example, the cross-sectional shape of the first through hole 45 along the first direction X may be a rectangle, a trapezoid, a circle, an ellipse, a polygon, or the like.

[0211] In some examples, step S411 may include: forming at least one first through hole 45 extending along the second direction Y in the planar layer 50 by using an etching process.

[0212] The first through hole 45 is at least disposed between the first light emitting device 21 and the second light emitting device 22 which are of the same color and adjacent to each other.

[0213] Exemplarily, the first through hole 45 may be disposed between the first light emitting device 21 and the second light emitting device 22 of the same color and adjacent to each other.

[0214] Exemplarily, the first through hole 45 may also be disposed between a first light emitting device 21 and a second light emitting device 22 that are of different colors and adjacent to each other.

[0215] For example, one first through hole 45 may be provided between the plurality of first light emitting devices 21 and the plurality of second light emitting devices 22. The plurality of first light emitting devices 21 are located on one side of the first through hole 45, and the plurality of second light emitting devices 22 are located on the other side of the first through hole 45. Alternatively, a portion of the plurality of first light emitting devices 21 and a portion of the second light emitting devices 22 are located on one side of the first through hole 45, and another portion of the plurality of first light emitting devices 21 and another portion of the second light emitting devices 22 are located on the other side of the first through hole 45.

[0216] Exemplarily, in step S411, two first through holes 45 extending along the second direction Y are formed in the planar layer 50. The two first through holes 45 are respectively disposed on both sides of the second light emitting device 22. One of the first through holes 45 may be disposed between the first light emitting device 21 and the second light emitting device 22 of the same color and adjacent to each other, and the other first through hole 45 may be disposed between the first light emitting device 21 and the second light emitting device 22 of different colors and adjacent to each other.

[0217] Step S412: forming the light shielding body 40 in the first through hole 45. For example, step S412 may include: forming the light shielding body 40 in the first through hole 45 by coating.

[0218] In this way, the process of forming the light shielding body 40 is relatively simple, thereby simplifying the manufacturing process of the display panel 100 and the display device 1000. The wide-angle light emitted from the second light-emitting device 22 can enter the light shielding body 40 in the flat layer 50, and the light shielding body 40 can block and absorb the wide-angle light that would otherwise be transmitted through the flat layer 50 to the outside of the display device 1000, and can limit the emission angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, and improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0219] In some embodiments, Fig. 9A , Fig. 9C , Fig.13A and Fig. 13B As shown, the light shield 40 is at least disposed between the first light emitting device 21 and the second light emitting device 22. It can be understood that the light shield 40 can be disposed between the first light emitting device 21 and the second light emitting device 22; and / or, the light shield 40 can be disposed between two adjacent second light emitting devices 22 of different colors.

[0220] For example, in the case where the light-shielding body 40 is disposed on one side of the second light-emitting device 22 , the light-shielding body 40 may be disposed between the first light-emitting device 21 and the second light-emitting device 22 .

[0221] Exemplarily, when the light shielding body 40 is disposed on both sides of the second light emitting device 22, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22, and the light shielding body 40 may be disposed between two adjacent second light emitting devices 22 of different colors.

[0222] In this way, when the wide-angle output light emitted from the second light-emitting device 22 enters the light-shielding body 40, the light-shielding body 40 can at least block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 to the outside of the display device 1000, and can limit the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0223] In some examples, such as Fig. 9C and Fig. 13B As shown, the light shielding body 40 is at least disposed between the first light emitting device 21 and the second light emitting device 22 which are of the same color and adjacent to each other.

[0224] For example, when the light shielding body 40 is disposed on one side of the second light emitting device 22, Figure 5 , Fig.13A and Figures 14 to 18A As shown, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22 which are of the same color and adjacent to each other.

[0225] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40, and the light-shielding body 40 can at least block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of the same color and adjacent to each other to the outside of the display device 1000, and can limit the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0226] For example, Fig. 9C As shown, the light shielding body 40 may be disposed between the first light emitting device 21 and the second light emitting device 22 that are different in color and adjacent to each other.

[0227] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40, and the light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of different colors and adjacent to each other to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0228] For example, when the light shielding body 40 is disposed on both sides of the second light emitting device 22, Fig. 9A and Figure 10 to Figure 12 As shown, the light shielding body 40 includes a first light shielding body 41 and a second light shielding body 42 respectively located on both sides of the second light emitting device 22. The first light shielding body 41 is arranged between the first light emitting device 21 and the second light emitting device 22 of the same color and adjacent to each other, and the second light shielding body 42 is arranged between the first light emitting device 21 and the second light emitting device 22 of different colors and adjacent to each other.

[0229] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the first light-shielding body 41 and the second light-shielding body 42. The first light-shielding body 41 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of the same color and adjacent to each other to the outside of the display device 1000. The second light-shielding body 42 can block and absorb the wide-angle output light that would originally be transmitted from between the first light-emitting device 21 and the second light-emitting device 22 of different colors and adjacent to each other to the outside of the display device 1000. The output angle range of the second light-emitting device 22 can be greatly limited, thereby greatly reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby greatly improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0230] In some examples, such as Fig. 13B As shown, a light shielding body 40 may be disposed between the plurality of first light emitting devices 21 and the plurality of second light emitting devices 22 .

[0231] The plurality of first light emitting devices 21 may be located on one side of the light shielding body 40, and the plurality of second light emitting devices 22 may be located on the other side of the light shielding body 40. Alternatively, a portion of the plurality of first light emitting devices 21 and a portion of the second light emitting devices 22 are located on one side of the light shielding body 40, and another portion of the plurality of first light emitting devices 21 and another portion of the second light emitting devices 22 are located on the other side of the light shielding body 40.

[0232] In this way, the wide-angle output light emitted from the multiple second light-emitting devices 22 can enter a light-shielding body 40. A light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the multiple first light-emitting devices 21 and the multiple second light-emitting devices 22 to the outside of the display device 1000. A light-shielding body 40 can limit the output angle range of the multiple second light-emitting devices 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0233] In some examples, such as Fig. 9C , Fig. 13B and Fig.18B As shown, a light shielding body 40 may be disposed between two adjacent second light emitting devices 22 of different colors.

[0234] In this way, the wide-angle output light emitted from two second light-emitting devices 22 that are adjacent to each other and have different colors can enter a light-shielding body 40. A light-shielding body 40 can block and absorb the wide-angle output light that would originally be transmitted from between the two second light-emitting devices 22 that are adjacent to each other and have different colors to the outside of the display device 1000. A light-shielding body 40 can limit the output angle range of the two second light-emitting devices 22 that are adjacent to each other and have different colors, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0235] In some embodiments, Fig. 9C As shown, in the first direction X, the distance d between the light shading body 40 and the side wall of the second light emitting device 22 adjacent to the light shading body 40 is less than or equal to 5μm, for example, d can be 0μm, 0.5μm, 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm or 5μm.

[0236] By limiting the distance d between the light shield 40 and the side wall of the second light emitting device 22 and adjacent to the light shield 40 within a smaller range, most of the wide-angle output light emitted from the second light emitting device 22 can enter the light shield 40. The light shield 40 can block and absorb most of the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, and can limit the output angle range of the second light emitting device 22, thereby reducing the light emission angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0237] In some embodiments, Fig. 9C As shown, the extension direction of a light shield 40 is substantially parallel to one side of the second light emitting device 22. The extension length L1 of the light shield 40 is greater than or equal to the length L2 of one side of the second light emitting device 22. It can be understood that along the first direction X, the length L1 of the light shield 40 is greater than or equal to the length L2 of one side of the second light emitting device 22.

[0238] In this way, the wide-angle output light emitted from the second light-emitting device 22 enters the light-shielding body 40. The light-shielding body 40 can block and absorb all the wide-angle output light that would originally be transmitted from the side of the second light-emitting device 22 parallel to the light-shielding body 40 to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0239] In some embodiments, along the second direction Y, the light shielding body 40 may be an integrated structure formed by multiple patterning processes. Fig.18A and Fig.21 As shown, step S400 may also include steps S420 to S421.

[0240] Step S420 : forming a sub-light-shielding body 43 on a side of the first light-blocking body 30 away from the base substrate 10 .

[0241] Exemplarily, step S420 may include: forming a sub-light-shielding body 43 on a side of the first photoresist 30 away from the base substrate 10 by coating, exposing and developing processes.

[0242] For example, the cross-sectional shape of the sub-light-shielding body 43 along the first direction X may include a rectangle, a trapezoid, a circle, an ellipse, a polygon, and the like.

[0243] Step S421: The plurality of sub-light-shielding bodies 43 are stacked in sequence along the second direction Y by repeating the above step S420 so that the plurality of sub-light-shielding bodies 43 together form the light-shielding body 40 .

[0244] Along the second direction Y, according to the size of the sub-light shielding body 43 (i.e., the thickness of the sub-light shielding body 43) and the coating size (i.e., thickness) in a single coating process, the number of coating, exposure, and development processes in the process of forming the sub-light shielding body 43 can be selected. For example, the coating thickness in a single coating process can be 2 μm.

[0245] After step S421 , the method may include: forming a planar layer 50 on a side of the first photoresist 30 away from the base substrate 10 by sequentially using an inkjet printing process and a curing process, wherein the light shielding body 40 is located in the planar layer 50 .

[0246] In this way, the planarization layer 50 can be manufactured after the light shielding body 40 is formed.

[0247] In other embodiments, Fig.13A , Fig. 13B and Figure 14 to Figure 16 As shown, along the second direction Y, the light shielding body 40 may be a split structure, and the light shielding body 40 may include a plurality of sub-light shielding bodies 43, and the plurality of sub-light shielding bodies 43 are sequentially arranged at intervals along the second direction Y. Fig. 22 As shown, step S400 may include steps S430 to S432.

[0248] Step S430 : forming a sub-light-shielding body 43 on a side of the first light-blocking body 30 away from the base substrate 10 .

[0249] The specific process of forming the sub-light shielding body 43 in step S430 can refer to step S420, which will not be repeated here.

[0250] The size of the sub-light shielding body 43 formed in step S430 along the second direction Y may be the same as or different from the size of the sub-light shielding body 43 formed in step S420 along the second direction Y, which is not limited here.

[0251] For example, the cross-sectional shape of the sub-light-shielding body 43 along the first direction X may include a rectangle, a trapezoid, a circle, an ellipse, a polygon, and the like.

[0252] Step S431 : forming a sub-planarization layer 50 on a side of the sub-light shielding body 43 away from the base substrate 10 .

[0253] Exemplarily, step S431 may include: forming a sub-planarization layer 50 on a side of the sub-light-shielding body 43 away from the base substrate 10 by sequentially performing an inkjet printing process and a curing process.

[0254] Step S432 : repeating the above steps S430 and S431 in sequence, so that the plurality of sub-light shielding bodies 43 and the plurality of sub-planar layers 50 are alternately stacked in sequence along the second direction Y, and the plurality of sub-light shielding bodies 43 together form the light shielding body 40 . The plurality of sub-planar layers 50 together form the planar layer 50 .

[0255] Exemplarily, along the second direction Y, the size of the sub-light-shielding body 43 (i.e., the thickness of the sub-light-shielding body 43) d1 can be greater than or equal to 1μm and less than or equal to 5μm. For example, the thickness of the sub-light-shielding body 43 can be 1μm, 1.5μm, 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm or 5μm.

[0256] Exemplarily, the thickness d1 of the sub-light-shielding body 43 and the dimension of the sub-planarizing layer 50 along the second direction Y (ie, the thickness of the sub-planarizing layer 50 ) may be the same as or different from each other, which is not limited herein.

[0257] In this way, when the wide-angle outgoing light emitted from the second light-emitting device 22 enters the multiple sub-light shields 43, the multiple sub-light shields 43 can block and absorb the wide-angle outgoing light that would otherwise be transmitted to the outside of the display device 1000, and can limit the range of the outgoing angle of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state. Improve the anti-peeping display effect of the display panel 100 and the display device 1000. On the basis of improving the anti-peeping display effect of the display panel 100 and the display device 1000, the multiple sub-light shields 43 can also reduce the blocking and absorption of the display light emitted from the first light-emitting device 21, thereby ensuring the screen sharing display effect of the display panel 100 and the display device 1000.

[0258] In some examples, such as Fig.13AAs shown, along the second direction Y, the spacing d2 between two adjacent sub-light shielding bodies 43 may be greater than or equal to 1.5 μm and less than or equal to 15 μm. For example, the spacing d2 between two adjacent sub-light shielding bodies 43 may be 1.5 μm, 2 μm, 3 μm, 5 μm, 7 μm, 8 μm, 9 μm, 10 μm, 12 μm, 14 μm or 15 μm. The spacing d2 between two adjacent sub-light shielding bodies 43 may be the same as or different from the thickness d1 of a sub-light shielding body 43, which is not limited here.

[0259] On the basis that multiple sub-light-shielding bodies 43 can improve the anti-peeping display effect of the display panel 100 and the display device 1000, by limiting the distance d2 between two adjacent sub-light-shielding bodies 43 within a suitable range, the shielding and absorption of the display light emitted from the first light-emitting device 21 by the multiple sub-light-shielding bodies 43 can be greatly reduced, thereby better ensuring the screen sharing display effect of the display panel 100 and the display device 1000.

[0260] In some embodiments, Fig.23 As shown, step S500 may be further included after step S200.

[0261] Step S500 : forming a light shielding body 40 on a side of the base substrate 10 close to the light emitting unit 20 .

[0262] In some examples, such as Fig.10 As shown, along the second direction Y, the light shielding body 40 may be an integrated structure formed by a single patterning process.

[0263] Exemplarily, step S500 may include: forming at least one second through hole 46 extending in the second direction Y in the encapsulation layer TFE. The second through hole 46 is at least disposed between the first light emitting device 21 and the second light emitting device 22 .

[0264] For example, the second through hole 46 may extend from the first photoresist 30 to the second inorganic layer TFE3 of the encapsulation layer TFE along the second direction Y. For another example, the second through hole 46 may extend from the first photoresist 30 to the second inorganic layer TFE3 and the organic layer TFE2 of the encapsulation layer TFE along the second direction Y. For another example, the second through hole 46 may extend from the first photoresist 30 to the entire encapsulation layer TFE along the second direction Y.

[0265] The orthographic projection of the outer contour of the second through hole 46 on the substrate substrate 10 at least partially overlaps with the orthographic projection of the outer contour of the first through hole 45 on the substrate substrate 10. It can be understood that the orthographic projection of the outer contour of the second through hole 46 on the substrate substrate 10 may partially overlap with the orthographic projection of the outer contour of the first through hole 45 on the substrate substrate 10; or, the orthographic projection of the outer contour of the second through hole 46 on the substrate substrate 10 may completely overlap with the orthographic projection of the outer contour of the first through hole 45 on the substrate substrate 10.

[0266] The cross-sectional shape of the second through hole 46 along the first direction X may be the same as or different from the cross-sectional shape of the first through hole 45 along the first direction X, which is not limited here.

[0267] The relative positional relationship between the second through hole 46 and the light emitting device may be the same as the relative positional relationship between the first through hole 45 and the light emitting device, and will not be described in detail herein.

[0268] After the second through hole 46 is formed, the light shielding body 40 is formed in the second through hole 46 .

[0269] In some examples, when the light-shielding body 40 is located at one side of the first light blocker 30 , the light-shielding body 40 may extend along the second direction Y from the first light blocker 30 into the encapsulation layer TFE.

[0270] In some other examples, the light shielding body 40 is located on both sides of the first light blocking body 30, such as Fig.10 and Fig.14 As shown, the light-shielding body 40 may extend along the second direction Y from the planar layer 50 into the encapsulation layer TFE.

[0271] For example, the light shielding body 40 may extend from the flat layer 50 to the second inorganic layer TFE3 of the encapsulation layer TFE along the second direction Y. For another example, the light shielding body 40 may extend from the flat layer 50 to the second inorganic layer TFE3 and the organic layer TFE2 of the encapsulation layer TFE along the second direction Y. For another example, the light shielding body 40 may extend from the flat layer 50 to the entire encapsulation layer TFE along the second direction Y.

[0272] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light shielding body 40 in the encapsulation layer TFE. The light shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted through the encapsulation layer TFE to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0273] For example, Fig.11 and Fig.17As shown, step S500 may include: forming at least one second through hole 46 extending along the second direction Y in the encapsulation layer TFE and the pixel definition layer PDL. The second through hole 46 is at least disposed between the first light emitting device 21 and the second light emitting device 22. After the second through hole 46 is formed, a light shielding body 40 is formed in the second through hole 46.

[0274] In some examples, when the light shielding body 40 is located on one side of the first photoblocker 30 , the pixel defining layer PDL may be made of a semi-transmissive material, and the light shielding body 40 may extend along the second direction Y from the first photoblocker 30 into the pixel defining layer PDL.

[0275] In some other examples, when the light shielding body 40 is located on both sides of the first light blocking body 30, the pixel defining layer PDL may be made of a semi-transparent material, such as Fig.11 , Fig.15 and Fig.17 As shown, the light-shielding body 40 may extend along the second direction Y from the planar layer 50 into the pixel defining layer PDL.

[0276] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the light-shielding body 40 in the pixel defining layer PDL. The light-shielding body 40 in the pixel defining layer PDL can completely block and absorb the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0277] In some examples, when the light shielding body 40 is located on one side of the first photoblocker 30 , the pixel defining layer PDL can be made of black light shielding material, and the light shielding body 40 can extend along the second direction Y from the first photoblocker 30 to the surface of the pixel defining layer PDL away from the base substrate 10 .

[0278] In some other examples, when the light shielding body 40 is located on both sides of the first light blocking body 30, the pixel defining layer PDL may be made of a black light shielding material, such as Fig.12 and Fig.16 As shown, the light shielding body 40 may also extend along the second direction Y from the planar layer 50 to the surface of the pixel defining layer PDL away from the base substrate 10 .

[0279] In this way, the wide-angle output light emitted from the second light-emitting device 22 can enter the pixel defining layer PDL and the light-shielding body 40. The pixel defining layer PDL and the light-shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0280] In some examples, such as Fig.10 As shown, along the second direction Y, the light shielding body 40 may be an integrated structure formed by multiple patterning processes.

[0281] Step S500 may include: forming a sub-light shielding body 43 on a side of the light emitting unit 20 away from the base substrate 10 by coating, exposing and developing processes.

[0282] Afterwards, by repeating the coating, exposure and development processes for multiple times, a plurality of sub-light-shielding bodies 43 stacked in sequence along the second direction Y are formed, so that the plurality of sub-light-shielding bodies 43 together form the light-shielding body 40 .

[0283] Afterwards, a packaging layer TFE is formed by a deposition process on the side of the light emitting unit 20 away from the base substrate 10. The light shield 40 is embedded in the packaging layer TFE, and the position where the light shield 40 and the packaging layer TFE are joined is sealed. The position where the light shield 40 and the packaging layer TFE are joined has sealing performance and can isolate water and oxygen.

[0284] In this way, when the wide-angle output light emitted from the second light-emitting device 22 enters the light-shielding body 40 in the encapsulation layer TFE, the light-shielding body 40 can block and absorb the wide-angle output light that would otherwise be transmitted through the encapsulation layer TFE to the outside of the display device 1000, thereby limiting the output angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in an anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000.

[0285] In other examples, such as Fig.14 As shown, the light shielding body 40 may be a split structure along the second direction Y. The light shielding body 40 may include a plurality of sub-light shielding bodies 43, and the plurality of sub-light shielding bodies 43 are sequentially arranged along the second direction Y at intervals.

[0286] Step S500 may refer to steps S430 to S432, which will not be described in detail here.

[0287] In this way, the wide-angle outgoing light emitted from the second light-emitting device 22 can enter the multiple sub-light shields 43, and the multiple sub-light shields 43 can block and absorb the wide-angle outgoing light that would otherwise be transmitted to the outside of the display device 1000, and can limit the range of the outgoing angle of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state. Improve the anti-peeping display effect of the display panel 100 and the display device 1000. On the basis of improving the anti-peeping display effect of the display panel 100 and the display device 1000, the multiple sub-light shields 43 can also reduce the blocking and absorption of the display light emitted from the first light-emitting device 21, thereby ensuring the screen sharing display effect of the display panel 100 and the display device 1000.

[0288] In summary, in the display panel 100 prepared by the method for preparing the display panel 100 provided by the embodiment of the present disclosure, the wide-angle exit light emitted from the second light-emitting device 22 can enter the first light-blocking body 30 and the light-shielding body 40, and the first light-blocking body 30 and the light-shielding body 40 can block and absorb the wide-angle exit light that would otherwise be transmitted from the second light-emitting device 22 to the outside of the display device 1000, and can limit the exit angle range of the second light-emitting device 22, thereby reducing the light-emitting angle of the display panel 100 and the display device 1000 when they are in the anti-peeping display state, thereby improving the anti-peeping display effect of the display panel 100 and the display device 1000. In addition, the first light-blocking body 30 can also prevent light of different colors emitted from other light-emitting areas EA from entering the light-emitting area EA, so as to ensure the color purity of the light emitted from each light-emitting area EA, and improve the contrast of the color of the light emitted from each light-emitting area EA, thereby improving the display effect of the display panel 100 and the display device 1000.
