Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a display terminal. Background Technology

[0002] Today, consumers are significantly more aware of the privacy and security of display devices. In scenarios such as public transportation and workplaces, the risk of screen information being spied on by others is receiving increasing attention. Privacy protection displays have gradually transformed from high-end add-ons into essential features for the general public. People are no longer just pursuing display quality and a smooth experience; their demand for controllable viewing angles and side-view protection is growing stronger. The privacy protection effect directly affects the user's sense of security when using a display device and their purchasing decisions, and has also become an important indicator for measuring the overall competitiveness of display devices.

[0003] To achieve a privacy protection effect, privacy pixels need to be added. Since privacy pixels require additional area, the aperture ratio of the pixels decreases, which in turn reduces the lifespan of the pixels. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0025] According to the first aspect of this application, Figures 1 to 4 As shown, a display panel 1 is provided, including multiple pixel groups 100. Each pixel group 100 includes a privacy-protected light-emitting part 110 and a non-privacy-protected light-emitting part 120. The maximum light emission angle of the privacy-protected light-emitting part 110 is smaller than the maximum light emission angle of the non-privacy-protected light-emitting part 120. The privacy-protected light-emitting part 110 and the non-privacy-protected light-emitting part 120 within the same pixel group 100 emit light of the same wavelength. In at least one pixel group 100, the area of ​​the non-privacy-protected light-emitting part 120 is larger than the area of ​​the privacy-protected light-emitting part 110.

[0026] In some embodiments, the display panel 1 may be an OLED (Organic Light-Emitting Diode) panel.

[0027] like Figure 1 As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA can be provided with multiple sub-pixels, which can be red, green, or blue sub-pixels of different emitting colors, thereby achieving color display. The display area AA is provided with a pixel driving circuit, which is used to drive the sub-pixels to display. The non-display area NA can be provided with a gate driving circuit, etc., which can provide driving signals to the sub-pixels.

[0028] The privacy-protecting light-emitting part 110 and the non-privacy-protecting light-emitting part 120 within the same pixel group 100 emit light of the same wavelength. This means that the emitted light colors of the privacy-protecting light-emitting part 110 and the non-privacy-protecting light-emitting part 120 within the same pixel group 100 can be the same or similar. "Same" means the emitted light color is visually consistent, for example, both are red. "Similar" means the emitted light color is visually close, for example, dark red and light red are similar, dark green and light green are similar, dark blue and light blue are similar, etc.

[0029] It should be noted that the privacy light-emitting portion 110 refers to the portion of the sub-pixel used for emitting light. For example, the sub-pixel may also include an anode located on one side of the privacy light-emitting portion 110 and a cathode located on the other side of the privacy light-emitting portion 110. The anode provides holes, and the cathode provides electrons; the holes and electrons recombine in the privacy light-emitting portion 110 to emit light.

[0030] The privacy-protecting light-emitting part 110 is used to achieve the privacy protection function, while the non-privacy-protecting light-emitting part 120 is used to achieve the display function.

[0031] In some embodiments, the privacy-protecting light-emitting part 110 and the non-privacy-protecting light-emitting part 120 can be formed by a vapor deposition process.

[0032] It should be noted that the non-privacy light-emitting portion 120 refers to the portion of the sub-pixel used for emitting light. For example, the sub-pixel may also include an anode located on one side of the non-privacy light-emitting portion 120 and a cathode located on the other side of the non-privacy light-emitting portion 120. The anode provides holes, and the cathode provides electrons; the holes and electrons recombine in the non-privacy light-emitting portion 120 to emit light.

[0033] In some embodiments, such as Figure 4 As shown, the display panel 1 also includes a pixel definition layer 50, which has multiple pixel openings. The pixel openings expose the anode located below the pixel definition layer 50. A privacy-protected light-emitting part 110 is located inside one pixel opening and contacts the exposed anode. A non-privacy-protected light-emitting part 120 is located inside another pixel opening and contacts the exposed anode.

[0034] In some embodiments, the maximum light emission angle of the privacy-protecting light-emitting unit 110 is smaller than the maximum light emission angle of the non-privacy-protecting light-emitting unit 120. The light emission angle of the privacy-protecting light-emitting unit 110 refers to the angle between the light emitted from the light-emitting surface of the display panel 1 and the normal to the light-emitting surface. The maximum light emission angle of the privacy-protecting light-emitting unit 110 refers to the largest value among the light emission angles of the privacy-protecting light-emitting unit 110.

[0035] The light emission angle of the non-privacy light-emitting unit 120 refers to the angle between the light emitted from the light-emitting surface of the display panel 1 and the normal to the light-emitting surface. The maximum light emission angle of the non-privacy light-emitting unit 120 refers to the largest value among the light emission angles of the non-privacy light-emitting unit 120.

[0036] Because the maximum light emission angle of the privacy-protecting light-emitting unit 110 is smaller than that of the non-privacy-protecting light-emitting unit 120, when privacy display mode is required, the privacy-protecting light-emitting unit 110 is illuminated, while the non-privacy-protecting light-emitting unit 120 is not illuminated. The smaller maximum light emission angle of the privacy-protecting light-emitting unit 110 results in lower screen brightness at wide viewing angles, thus preventing others from observing the display from a side view. When the user views the screen at a near-frontal angle, the light from the privacy-protecting pixel 11 is visible, allowing normal viewing of the display. When non-privacy display mode is required, the non-privacy-protecting light-emitting unit 120 is illuminated. At this time, the larger maximum light emission angle of the non-privacy-protecting light-emitting unit 120 allows it to be observed by others, thus achieving non-privacy display mode.

[0037] In other embodiments, in the non-peeping display mode, the non-peeping light-emitting part 120 and the peeping light-emitting part 110 can be lit simultaneously.

[0038] The area of ​​the non-privacy light-emitting part 120 is larger than the area of ​​the privacy light-emitting part 110. In other words, the area of ​​the orthographic projection pattern of the non-privacy light-emitting part 120 on the display surface of the display panel 1 is larger than the area of ​​the orthographic projection pattern of the privacy light-emitting part 110 on the display surface of the display panel 1.

[0039] In the display panel 1 of this application embodiment, by setting the area of ​​the non-privacy light-emitting part 120 to be larger than the area of ​​the privacy light-emitting part 110, the aperture ratio of the non-privacy light-emitting part 120 can be increased, and the lifespan of the non-privacy light-emitting part 120 can be improved.

[0040] It should be noted that there is a correlation between the area of ​​the light-emitting part and its lifespan. The smaller the area of ​​the light-emitting part, the faster its lifespan decays, resulting in a significant reduction in lifespan. Therefore, increasing the area of ​​the light-emitting part is beneficial for improving its lifespan.

[0041] Optionally, the display panel 1 includes a plurality of pixel units 10, which are arranged along a first direction D1 and a second direction D2. Each pixel unit 10 includes three pixel groups 100, each pixel group 100 including three privacy-protected light-emitting parts 110 and three non-privacy-protected light-emitting parts 120. The three privacy-protected light-emitting parts 110 include a first light-emitting part 111, a second light-emitting part 112, and a third light-emitting part 113 of different light-emitting colors. The three non-privacy-protected light-emitting parts 120 include a fourth light-emitting part 121, a fifth light-emitting part 122, and a sixth light-emitting part 123 of different light-emitting colors. One pixel group 100 includes the first light-emitting part 111 and the fourth light-emitting part 121, another pixel group 100 includes the second light-emitting part 112 and the fifth light-emitting part 122, and another pixel group 100 includes the third light-emitting part 113 and the sixth light-emitting part 123. The first direction D1 and the second direction D2 intersect, and both the first direction D1 and the second direction D2 are perpendicular to the thickness direction of the display panel 1.

[0042] like Figure 2 As shown, Figure 2 Only a portion of the pixel units 10 in the display area AA is shown. Pixel units 10 can serve as the smallest repeating unit. Multiple pixel units 10 are arranged along a first direction D1, and multiple pixel units 10 are arranged along a second direction D2.

[0043] like Figure 2 and Figure 3 As shown, a pixel unit 10 may include three pixel groups 100, each pixel group 100 including a non-privacy light-emitting part 120 and a privacy light-emitting part 110. The three pixel groups 100 emit different colors, and the non-privacy light-emitting part 120 and the privacy light-emitting part 110 in each pixel group 100 emit light of the same wavelength. In the three pixel groups 100, one pixel group 100 includes a first light-emitting part 111 and a fourth light-emitting part 121, another pixel group 100 includes a second light-emitting part 112 and a fifth light-emitting part 122, and another pixel group 100 includes a third light-emitting part 113 and a sixth light-emitting part 123.

[0044] Multiple privacy light-emitting parts 110 of different colors mix to form white light. In the same pixel unit 10, a first light-emitting part 111, a second light-emitting part 112, and a third light-emitting part 113 can form a privacy pixel 11. The first light-emitting part 111 can emit red light, the second light-emitting part 112 can emit green light, and the third light-emitting part 113 can emit blue light. Each of the first light-emitting part 111, the second light-emitting part 112, and the third light-emitting part 113 can correspond to a sub-pixel. A privacy pixel 11 can include at least three sub-pixels of different colors.

[0045] like Figure 3 and Figure 4As shown, multiple non-privacy light-emitting parts 120 mix to form white light. In the same pixel unit 10, the fourth light-emitting part 121, the fifth light-emitting part 122, and the sixth light-emitting part 123 can form a non-privacy pixel 12. The light emitted by the fourth light-emitting part 121 can be red, the light emitted by the fifth light-emitting part 122 can be green, and the light emitted by the sixth light-emitting part 123 can be blue. The fourth light-emitting part 121, the fifth light-emitting part 122, and the sixth light-emitting part 123 can each correspond to a sub-pixel. A non-privacy pixel 12 can include at least three sub-pixels with different light-emitting colors.

[0046] In some embodiments, such as Figures 1 to 3 As shown, the first direction D1 can be the vertical direction in the figure, and the second direction D2 can be the horizontal direction in the figure. The first direction D1 and the second direction D2 intersect, and the angle between the first direction D1 and the second direction D2 can be a right angle or an acute angle.

[0047] In some embodiments, the area of ​​the sixth light-emitting part 123 is larger than the area of ​​the third light-emitting part 113. That is to say, the area of ​​the orthographic projection pattern of the sixth light-emitting part 123 on the display surface of the display panel 1 is larger than the area of ​​the orthographic projection pattern of the third light-emitting part 113 on the display surface of the display panel 1.

[0048] In the display panel 1 of this application embodiment, by setting the area of ​​the sixth light-emitting part 123 to be larger than the area of ​​the third light-emitting part 113, the aperture ratio of the sixth light-emitting part 123 can be increased and the lifespan of the sixth light-emitting part 123 can be improved.

[0049] It should be noted that the light-emitting part with the fastest lifespan decay among the three colors can be designated as the third light-emitting part 113. For example, since the blue light-emitting part typically decays the fastest, the light-emitting color of the third light-emitting part 113 can be set to blue. The light-emitting colors of the first light-emitting part 111 and the second light-emitting part 112 can be either red or green, respectively.

[0050] Optionally, such as Figure 3 As shown, in the first direction D1, the size of the sixth light-emitting part 123 is greater than or equal to the size of the third light-emitting part 113; and / or, in the second direction D2, the size of the sixth light-emitting part 123 is greater than or equal to the size of the third light-emitting part 113. Through the above arrangement, the area of ​​the sixth light-emitting part 123 can be larger than the area of ​​the third light-emitting part 113.

[0051] Optionally, such as Figure 3 As shown, the shape of the orthographic projection pattern of the third light-emitting part 113 on the display surface of the display panel 1 is different from the shape of the orthographic projection pattern of the sixth light-emitting part 123 on the display surface of the display panel 1.

[0052] In some embodiments, the orthographic projection pattern of the third light-emitting part 113 on the display surface of the display panel 1 can be circular. With the above-mentioned arrangement, the third light-emitting part 113 can emit light uniformly in all directions, thereby achieving a better privacy protection effect.

[0053] In some embodiments, the orthographic projection pattern of the sixth light-emitting part 123 on the display surface of the display panel 1 can be a rectangle, a square, or the like. Since the sixth light-emitting part 123 is a non-privacy pixel 12, and the non-privacy pixel 12 is not sensitive to shape requirements, the orthographic projection pattern of the sixth light-emitting part 123 can be set as a rectangle.

[0054] Optionally, such as Figure 3 , Figure 5 and Figure 6 As shown, the orthographic projection pattern of the third light-emitting part 113 on the display surface of the display panel 1 includes a circle, and the orthographic projection pattern of the sixth light-emitting part 123 on the display surface of the display panel 1 includes a polygon; and / or, the orthographic projection pattern of the first light-emitting part 111 on the display surface of the display panel 1 includes a circle, and the orthographic projection pattern of the fourth light-emitting part 121 on the display surface of the display panel 1 includes a polygon; and / or, the orthographic projection pattern of the second light-emitting part 112 on the display surface of the display panel 1 includes a circle, and the orthographic projection pattern of the fifth light-emitting part 122 on the display surface of the display panel 1 includes a rectangle.

[0055] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the orthographic projection pattern of the privacy pixel 11 on the display surface of the display panel 1 can be a circle, and the orthographic projection pattern of the non-privacy pixel 12 on the display surface of the display panel 1 can be a circle, a rectangle, a pentagon, etc.

[0056] Optionally, within the same pixel unit 10, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S5 between the first light-emitting part 111 and the third light-emitting part 113 on the display surface of the display panel 1; and / or, within the same pixel unit 10, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S6 between the second light-emitting part 112 and the third light-emitting part 113 on the display surface of the display panel 1.

[0057] In some embodiments, such as Figure 3As shown, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S5 between the first light-emitting part 111 and the third light-emitting part 113 on the display surface of the display panel 1. Through this arrangement, the distance between the third light-emitting part 113 and the sixth light-emitting part 123 in the first direction D1 can be reduced, thereby facilitating the outward expansion of the third light-emitting part 113 and / or the sixth light-emitting part 123, further increasing the area of ​​the third light-emitting part 113 and the sixth light-emitting part 123, and further improving the lifespan of the third light-emitting part 113 and the sixth light-emitting part 123.

[0058] In some embodiments, such as Figure 3 As shown, within the same pixel unit 10, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S6 between the second light-emitting part 112 and the third light-emitting part 113 on the display surface of the display panel 1. Through this arrangement, the distance between the third light-emitting part 113 and the sixth light-emitting part 123 in the first direction D1 can be reduced, thereby facilitating the outward expansion of the third light-emitting part 113 and / or the sixth light-emitting part 123, further increasing the area of ​​the third light-emitting part 113 and the sixth light-emitting part 123, and further improving the lifespan of the third light-emitting part 113 and the sixth light-emitting part 123.

[0059] In some embodiments, within the same pixel unit 10, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S5 between the first light-emitting part 111 and the third light-emitting part 113 on the display surface of the display panel 1; and within the same pixel unit 10, the distance S4 between the third light-emitting part 113 and the sixth light-emitting part 123 on the display surface of the display panel 1 is smaller than the distance S6 between the second light-emitting part 112 and the third light-emitting part 113 on the display surface of the display panel 1.

[0060] Optionally, such as Figure 3 As shown, within the same pixel unit 10, the line connecting the centers of the first light-emitting part 111, the second light-emitting part 112, and the third light-emitting part 113 forms an acute triangle, and the first light-emitting part 111 and the second light-emitting part 112 are arranged along the first direction D1.

[0061] It should be understood that the center of the light-emitting part is virtual and does not actually exist. The center of the light-emitting part can be its geometric center. The line connecting the centers of the first light-emitting part 111, the second light-emitting part 112, and the third light-emitting part 113 forms an acute triangle. This acute triangle is a virtual shape and does not actually exist.

[0062] In this embodiment, as Figure 3As shown, by forming an acute triangle with the line connecting the centers of the first light-emitting part 111, the second light-emitting part 112, and the third light-emitting part 113, the first light-emitting part 111 and the third light-emitting part 113 can be staggered in the second direction D2. At the same time, the second light-emitting part 112 and the third light-emitting part 113 can be staggered in the second direction D2. Under the condition that the minimum distance between the first light-emitting part 111 and the third light-emitting part 113 remains unchanged, and the minimum distance between the second light-emitting part 112 and the third light-emitting part 113 remains unchanged, the third light-emitting part 113 can be moved closer to the second light-emitting part 112 in the second direction D2, thereby saving a certain amount of space in the second direction D2. The saved space can be contributed to other privacy-protecting light-emitting parts 110 and / or non-privacy-protecting light-emitting parts 120, thereby increasing the area of ​​other privacy-protecting light-emitting parts 110 and / or non-privacy-protecting light-emitting parts 120. By increasing the area of ​​privacy-protecting light-emitting parts 110 and / or non-privacy-protecting light-emitting parts 120, the lifespan of privacy-protecting light-emitting parts 110 and / or non-privacy-protecting light-emitting parts 120 can be improved.

[0063] Optionally, such as Figure 3 As shown, the first light-emitting part 111 and the fourth light-emitting part 121 are arranged along the second direction D2, and the first light-emitting part 111 and the fourth light-emitting part 121 emit light of the same wavelength; the second light-emitting part 112 and the fifth light-emitting part 122 are arranged along the second direction D2, and the second light-emitting part 112 and the fifth light-emitting part 122 emit light of the same wavelength; the third light-emitting part 113 and the sixth light-emitting part 123 are arranged along the first direction D1, and the third light-emitting part 113 and the sixth light-emitting part 123 emit light of the same wavelength.

[0064] In some embodiments, the non-privacy light-emitting portion 120 and the privacy light-emitting portion 110 within the same pixel group 100 can be formed using the same photomask, that is, the non-privacy light-emitting portion 120 and the privacy light-emitting portion 110 within the same pixel group 100 can share the same vapor deposition opening on a photomask.

[0065] In some embodiments, such as Figure 3 As shown, the first light-emitting part 111 and the fourth light-emitting part 121 are arranged along the second direction D2. The light emission color of the first light-emitting part 111 and the fourth light-emitting part 121 can both be red. The first light-emitting part 111 and the fourth light-emitting part 121 can be formed using the same photomask, that is, the first light-emitting part 111 and the fourth light-emitting part 121 can be formed simultaneously by a single vapor deposition.

[0066] It should be noted that the light-emitting material layer 31 covers the area between the adjacent first light-emitting part 111 and the fourth light-emitting part 121.

[0067] In some embodiments, such as Figure 3As shown, the second light-emitting part 112 and the fifth light-emitting part 122 are arranged along the second direction D2. The light emission color of both the second light-emitting part 112 and the fifth light-emitting part 122 can be green. The second light-emitting part 112 and the fifth light-emitting part 122 can be formed using the same photomask, that is, the second light-emitting part 112 and the fifth light-emitting part 122 can be formed simultaneously by a single vapor deposition.

[0068] It should be noted that the light-emitting material layer 31 covers the area between the adjacent second light-emitting part 112 and the fifth light-emitting part 122.

[0069] In some embodiments, such as Figure 3 As shown, the third light-emitting part 113 and the sixth light-emitting part 123 are arranged along the second direction D2. The light emission color of the third light-emitting part 113 and the sixth light-emitting part 123 can both be blue. The third light-emitting part 113 and the sixth light-emitting part 123 can be formed using the same photomask, that is, the third light-emitting part 113 and the sixth light-emitting part 123 can be formed simultaneously by one vapor deposition.

[0070] It should be noted that the light-emitting material layer 31 covers the area between the adjacent third light-emitting part 113 and the sixth light-emitting part 123.

[0071] Optionally, such as Figure 3 As shown, within the same pixel unit 10, the distance s1 between the centers of the third light-emitting part 113 and the sixth light-emitting part 123 is greater than the distance s2 between the centers of the first light-emitting part 111 and the fourth light-emitting part 121; and / or, within the same pixel unit 10, the distance s1 between the centers of the third light-emitting part 113 and the sixth light-emitting part 123 is greater than the distance s3 between the centers of the second light-emitting part 112 and the fifth light-emitting part 122.

[0072] In some embodiments, such as Figure 3 As shown, within the same pixel unit 10, the distance s1 between the centers of the third light-emitting part 113 and the sixth light-emitting part 123 is greater than the distance s2 between the centers of the first light-emitting part 111 and the fourth light-emitting part 121. This arrangement increases the distance between the third light-emitting part 113 and the sixth light-emitting part 123 in the first direction D1, thereby further increasing the area of ​​the third light-emitting part 113 and the sixth light-emitting part 123 and further improving their lifespan.

[0073] In some embodiments, such as Figure 3As shown, within the same pixel unit 10, the distance s1 between the centers of the third light-emitting part 113 and the sixth light-emitting part 123 is greater than the distance s3 between the centers of the second light-emitting part 112 and the fifth light-emitting part 122. This arrangement increases the distance between the third light-emitting part 113 and the sixth light-emitting part 123 in the first direction D1, thereby further increasing the area of ​​the third light-emitting part 113 and the sixth light-emitting part 123 and further improving their lifespan.

[0074] Optionally, such as Figure 3 As shown, within the same pixel unit 10, in the first direction D1, the sixth light-emitting part 123 is located on the side away from the center of the first light-emitting part 111 and away from the third light-emitting part 113. That is, the sixth light-emitting part 123 is located on the side away from the third light-emitting part 113 along the line connecting the center of the first light-emitting part 111 and the center of the fourth light-emitting part 121. This arrangement increases the distance between the third light-emitting part 113 and the sixth light-emitting part 123, which is beneficial for increasing the area of ​​both parts and improving their lifespan. Simultaneously, by placing the sixth light-emitting part 123 on the side away from the third light-emitting part 113 along the line connecting the centers of the first and fourth light-emitting parts 121, the sixth light-emitting part 123 and the first light-emitting part 111 can be offset in the second direction D2, increasing the distance between them and reducing the requirements for process precision.

[0075] Optionally, such as Figure 3 and Figure 4 As shown, the display panel 1 also includes a substrate 20, a light-emitting layer 30, and a light-shielding layer 40; the light-emitting layer 30 is disposed on one side of the substrate 20, and the light-emitting layer 30 includes a plurality of privacy-protected light-emitting parts 110 and a plurality of non-privacy-protected light-emitting parts 120; the light-shielding layer 40 is disposed on the light-emitting side of the light-emitting layer 30, and the light-shielding layer 40 includes a plurality of spaced light-shielding parts 41, the light-shielding parts 41 being disposed between the privacy-protected light-emitting parts 110 and the non-privacy-protected light-emitting parts 120, and the minimum distance between the light-shielding parts 41 and the privacy-protected light-emitting parts 110 on the display surface of the display panel 1 is less than the minimum distance between the light-shielding parts 41 and the non-privacy-protected light-emitting parts 120 on the display surface of the display panel 1.

[0076] In some embodiments, the substrate 20 can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon. The flexible material can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0077] In some embodiments, the display panel 1 further includes a driving circuit layer (not shown) disposed between the substrate 20 and the light-emitting layer 30, the driving circuit layer being provided with a gate driving circuit and a pixel driving circuit.

[0078] In some embodiments, the light-emitting layer 30 is used to realize the light-emitting function. The light-emitting layer 30 may include a hole transport layer (HTL), an emissive material layer (EML), an electron transport layer (ETL), etc., stacked sequentially.

[0079] Both the privacy-protecting light-emitting part 110 and the non-privacy-protecting light-emitting part 120 belong to the light-emitting material layer 31. The privacy-protecting light-emitting part 110 and the non-privacy-protecting light-emitting part 120 can be formed by fabricating a fine metal mask plate.

[0080] In some embodiments, the light-emitting layer 30 may further include at least one of a hole injection layer (HIL) and an electron injection layer (EIL).

[0081] In some embodiments, such as Figure 4 As shown, the display panel 1 also includes an encapsulation layer 60, which is disposed on the side of the light-emitting layer 30 away from the substrate 20. The encapsulation layer 60 can be formed by alternatingly stacked one or more organic encapsulation layers 62 and one or more inorganic encapsulation layers 61. For example, the organic encapsulation layer 62 can be a single layer or multiple layers formed of any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic encapsulation layer 61 can be a single layer or multiple layers of metal oxide or metal nitride, such as silicon nitride, aluminum oxide, silicon oxide, etc.

[0082] In some embodiments, such as Figure 4 As shown, the display panel 1 also includes a first insulating layer 71 disposed between the encapsulation layer 60 and the light-shielding layer 40.

[0083] In some embodiments, such as Figure 3 and Figure 4As shown, the light-shielding layer 40 is made of a material with light-shielding capabilities, such as black ink, but is not limited to this. The light-shielding layer 40 has multiple spaced light-shielding portions 41, which are located between the privacy-protecting light-emitting portion 110 and the non-privacy-protecting light-emitting portion 120. Because the minimum distance between the light-shielding portion 41 and the privacy-protecting light-emitting portion 110 on the display surface of the display panel 1 is smaller than the minimum distance between the light-shielding portion 41 and the non-privacy-protecting light-emitting portion 120 on the display surface of the display panel 1, a portion of the light emitted from the privacy-protecting light-emitting portion 110 is blocked by the light-shielding portion 41, thereby reducing the maximum light emission angle of the privacy-protecting light-emitting portion 110. Conversely, the minimum distance between the light-shielding portion 41 and the non-privacy-protecting light-emitting portion 120 on the display surface of the display panel 1 is larger, thereby increasing the maximum light emission angle of the non-privacy-protecting light-emitting portion 120.

[0084] In some embodiments, combined with Figure 3 and Figure 4 The light-shielding portion 41 may include at least two sub-portions, and the two sub-portions are stacked in the thickness direction of the display panel 1. An insulating layer may be provided between the two sub-portions arranged in the thickness direction of the display panel 1.

[0085] like Figure 4 As shown, the light-shielding portion 41 includes three sub-parts with different layers, wherein a second insulating layer 72 and a third insulating layer 73 are disposed between two adjacent sub-parts. A fourth insulating layer 74 and a fifth insulating layer 75 are disposed between the other two adjacent sub-parts.

[0086] In some embodiments, the display panel 1 further includes a sixth insulating layer 76 located on the side of the light-shielding portion 41 away from the substrate 20.

[0087] In some embodiments, the first insulating layer 71, the second insulating layer 72, the third insulating layer 73, the fourth insulating layer 74, the fifth insulating layer 75, and the sixth insulating layer 76 can be inorganic insulating layers or organic insulating layers. The inorganic insulating layer can be a single layer or multiple layers formed from any of silicon oxide, silicon nitride, silicon oxynitride, etc. The organic insulating layer can be a single layer or multiple layers formed from any of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate.

[0088] like Figure 4 As shown, the light-shielding part 41 does not cover the non-privacy light-emitting part 120, thereby preventing the light-shielding part 41 from blocking the light from the non-privacy light-emitting part 120 at the normal viewing angle and affecting the display of the normal picture.

[0089] like Figure 4 As shown, the light-shielding part 41 does not cover the privacy light-emitting part 110, thereby preventing the light-shielding part 41 from blocking the light at the front viewing angle of the privacy light-emitting part 110 and affecting the display of the privacy light-emitting part 110.

[0090] In some embodiments, such as Figure 3 As shown, the orthographic projection pattern of the light-shielding part 41 on the substrate 20 is disposed around the orthographic projection pattern of the privacy light-emitting part 110 on the substrate 20, thereby achieving privacy protection from a 360-degree side viewing angle.

[0091] Optionally, combined Figure 3 and Figure 4 The light-shielding part 41 includes a first light-shielding part 411 corresponding to the first light-emitting part 111, a second light-shielding part 412 corresponding to the second light-emitting part 112, and a third light-shielding part 413 corresponding to the third light-emitting part 113; wherein, the orthographic projection pattern of the first light-shielding part 411 on the substrate 20 surrounds the orthographic projection pattern of the first light-emitting part 111 on the substrate 20; the orthographic projection pattern of the second light-shielding part 412 on the substrate 20 surrounds the orthographic projection pattern of the second light-emitting part 112 on the substrate 20; and the orthographic projection pattern of the third light-shielding part 413 on the substrate 20 surrounds the orthographic projection pattern of the third light-emitting part 113 on the substrate 20.

[0092] Optionally, the display panel 1 has a first display mode and a second display mode. In the first display mode, the non-peeping light-emitting part 120 emits light, while the peeping light-emitting part 110 does not emit light. In the second display mode, the peeping light-emitting part 110 emits light, while the non-peeping light-emitting part 120 does not emit light.

[0093] In some embodiments, the first display mode is a non-peeping display mode, in which there is no peeping effect. The non-peeping pixel 12 includes a plurality of non-peeping light-emitting parts 120, and the peeping pixel 11 includes a plurality of peeping light-emitting parts 110. In the first display mode, the non-peeping pixel 12 emits light to display the image. The peeping pixel 11 does not emit light. The second display mode is a peeping display mode, in which there is a peeping effect. In the second display mode, the peeping pixel 11 emits light, and the non-peeping pixel 12 does not emit light. The maximum light emission angle of the peeping pixel 11 is smaller than that of the non-peeping pixel 12, thus reducing the light emission of the peeping pixel 11 from a side viewing angle, resulting in a darker image that is less likely to be observed by a bystander from a side viewing angle, thereby achieving the peeping display mode.

[0094] According to the second aspect of this application, such as Figure 7 As shown, a display terminal 2 is provided, including the display panel 1 described above.

[0095] In this embodiment, as Figure 7 As shown, the display terminal 2 includes a display panel 1 and a terminal body 3, which are combined into one unit.
