Abstract

The application discloses a display panel and a display device. The display panel comprises a first light-emitting unit and a second light-emitting unit arranged adjacently. The first light-emitting unit comprises a first light-emitting element and a first transmission part. The second light-emitting unit comprises a second light-emitting element and a blocking part. When the first light-emitting element works and the second light-emitting element is closed, the first base color visible light emitted by the first light-emitting element can be transmitted from the corresponding first transmission part, and the display panel is in a normal display mode. When the first light-emitting element and the second light-emitting element both work, the first base color visible light emitted by the first light-emitting element and the first base color visible light under a side viewing angle emitted by the second light-emitting element can both be transmitted from the first transmission part, thereby enhancing the side viewing angle light emission of the display panel. Meanwhile, the first base color visible light under a normal viewing angle emitted by the second light-emitting element can be blocked by the corresponding blocking part, and the normal viewing angle light emission of the display panel is not affected. The display panel is in a peep-proof mode, and the peep-proof function is realized.

Description

Technical Field

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

[0002] With the development of display technology, there is an increasing desire for display panels to be readable only at a direct viewing angle, and to be unreadable at side or wide viewing angles, thus achieving privacy protection and preventing the leakage of important information. Therefore, there is an urgent need to design a display panel with privacy protection functionality. Summary of the Invention

[0003] To address the aforementioned technical problems, embodiments of this application provide a display panel and a display device, which provide a display panel and display device with privacy protection function.

[0004] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0005] A display panel, comprising:

[0006] Array substrate;

[0007] Multiple light-emitting units located on one side of the array substrate, including a first light-emitting unit and a second light-emitting unit arranged adjacent to each other;

[0008] The first light-emitting unit includes a first light-emitting element and a first transparent portion located on the side of the first light-emitting element away from the array substrate. The second light-emitting unit includes a second light-emitting element and a blocking portion located on the side of the second light-emitting element away from the array substrate. Both the first light-emitting element and the second light-emitting element are used to emit a first primary color visible light. The first transparent portion allows the first primary color visible light to pass through, and the blocking portion blocks the first primary color visible light from passing through.

[0009] When the first light-emitting element is in the working state and the second light-emitting element is in the off state, the display panel is in the first mode; when both the first light-emitting element and the second light-emitting element are in the working state, the display panel is in the second mode.

[0010] A display device includes the aforementioned display panel.

[0011] Compared with existing technologies, the above technical solution has the following advantages:

[0012] The display panel provided in this application embodiment, when the first light-emitting element is in a working state and the second light-emitting element is in a closed state, the first primary color visible light emitted by the first light-emitting element passes through the corresponding first transmission portion, and the display panel is in a first mode, i.e., a normal display mode. When both the first and second light-emitting elements are in a working state, not only does the first primary color visible light emitted by the first light-emitting element pass through the first transmission portion, but the first primary color visible light emitted by the second light-emitting element at a side viewing angle also passes through the first transmission portion, thereby enhancing the side viewing angle light emission of the display panel and preventing the display information of the display panel from being viewed from the side. At the same time, since the first primary color visible light emitted by the second light-emitting element at a frontal viewing angle is blocked by the corresponding blocking portion, it does not affect the frontal viewing angle light emission of the display panel. At this time, the display panel is in a second mode, i.e., an anti-peeping mode, thereby realizing the anti-peeping function. Therefore, the display panel provided in this application embodiment has an anti-peeping function. Attached Figure Description

[0029] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] Secondly, this application provides a detailed description in conjunction with schematic diagrams. When detailing the embodiments of this application, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this application. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] As described in the background section, there is an urgent need to design a display panel with privacy protection.

[0033] In view of this, embodiments of this application provide a display panel 100, Figure 1 and Figure 2 This illustration shows a cross-sectional structural diagram of a display panel provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the display panel 100 includes:

[0034] Array substrate 10;

[0035] Multiple light-emitting units 20 are located on one side of the array substrate 10, and the multiple light-emitting units 20 include a first light-emitting unit 21 and a second light-emitting unit 22 arranged adjacent to each other;

[0036] The first light-emitting unit 21 includes a first light-emitting element 211 and a first transmissive portion 212 located on the side of the first light-emitting element 211 facing away from the array substrate. The second light-emitting unit 22 includes a second light-emitting element 221 and a blocking portion 222 located on the side of the second light-emitting element 221 facing away from the array substrate. Both the first light-emitting element 211 and the second light-emitting element 221 are used to emit a first primary color visible light. The first transmissive portion 212 allows the first primary color visible light to pass through, and the blocking portion 222 blocks the first primary color visible light from passing through.

[0037] When the first light-emitting element 211 is in the working state and the second light-emitting element 221 is in the off state, such as Figure 1 As shown, the display panel 100 is in the first mode; when both the first light-emitting element 211 and the second light-emitting element 221 are in working state, as... Figure 2 As shown, the display panel is in the second mode.

[0038] In the display panel 100, the array substrate 10 includes a driving circuit, which is electrically connected to the light-emitting element in each light-emitting unit and is used to drive the light-emitting element to emit light.

[0039] In the display panel 100, both the first light-emitting element 211 and the second light-emitting element 221 are used to emit the first primary color visible light. Optionally, the first light-emitting element 211 and the second light-emitting element 221 have the same structure, and therefore, the manufacturing processes of the first light-emitting element 211 and the second light-emitting element 221 can also be the same, that is, the first light-emitting element 211 and the second light-emitting element 221 can be formed using the same process, which helps to simplify the manufacturing process of the display panel. Of course, alternatively, the first light-emitting element 211 and the second light-emitting element 221 can also have different structures, depending on the specific circumstances.

[0040] Optionally, the primary primary color visible light can be any one of red, green, and blue light, or other primary primary colors visible light, depending on the specific circumstances.

[0041] It is understandable that, such as Figure 1 and Figure 2 As shown by the solid arrow, the first primary color visible light emitted by the first light-emitting element 211 when it is in working state includes light from the frontal viewing angle (i.e., facing the display panel) and the side viewing angle. Similarly, the first primary color visible light emitted by the second light-emitting element 221 when it is in working state also includes light from the frontal viewing angle (i.e., facing the display panel) and the side viewing angle.

[0042] In specific operation, when the first light-emitting element 211 is in the working state and the second light-emitting element 221 is in the off state, such as Figure 1 As shown, the first primary color visible light emitted by the first light-emitting element 211 passes through the corresponding first transmission portion 212, including light from the frontal and side viewing angles. At this time, since the second light-emitting element 221 is in the off state, it will not affect the light transmitted through the first transmission portion 212, and the display panel 100 is in the first mode, that is, the normal display mode.

[0043] When both the first light-emitting element 211 and the second light-emitting element 221 are in working condition, such as Figure 2 As shown, not only does the first primary color visible light emitted by the first light-emitting element 211 pass through the first transmission portion 212, but the first primary color visible light emitted by the second light-emitting element 221 at a side viewing angle also passes through the first transmission portion 212. This enhances the side viewing angle light emission of the display panel and prevents the display information of the display panel from being viewed from the side. At the same time, since the first primary color visible light emitted by the second light-emitting element 221 at a frontal viewing angle is blocked by the corresponding block 222, it does not affect the frontal viewing angle light emission of the display panel. At this time, the display panel 100 is in the second mode, i.e., the anti-peeping mode, thereby realizing the anti-peeping function. It can be seen that the embodiments of this application provide a display panel with anti-peeping function.

[0044] In the display panel provided in this application embodiment, the first transmitting portion 212 allows the first primary color visible light to pass through, that is, the first primary color visible light can pass through the first transmitting portion 212 without being affected. The blocking portion 222 blocks the first primary color visible light from passing through, that is, the first primary color visible light cannot pass through the blocking portion 222 and is blocked by the blocking portion 222.

[0045] In the display panel provided in this application embodiment, the first light-emitting unit 21 is a normal light-emitting unit, and the second light-emitting unit 22 is a privacy protection unit. The privacy protection unit is formed by adding light-emitting elements that emit the same primary color light as the light-emitting elements in the normal light-emitting units at positions adjacent to some normal light-emitting units, and setting a blocking part on the side of the added light-emitting elements away from the array substrate. By controlling the working state of the privacy protection unit, when privacy protection is required, the light emission interference at a large viewing angle is prevented, while the front viewing angle display is not affected, thus achieving the privacy protection effect of side viewing interference.

[0046] Optionally, in one embodiment of this application, such as Figure 1 and Figure 2 As shown, the blocking portion 222 and the first transparent portion 212 are disposed in the same layer, thereby eliminating the need for an additional film layer where the blocking portion 222 is located, which simplifies the film layer structure of the display panel and simplifies the manufacturing process.

[0047] Further optionally, in one embodiment of this application, both the blocking portion 222 and the first transparent portion 212 are color resist materials.

[0048] We know that color resist can precisely select a small range of light wavelengths that are allowed to pass through, while reflecting other light wavelengths. For example, red color resist only allows red light to pass through, while blocking other light wavelengths; green color resist only allows green light to pass through, while blocking other light wavelengths; and blue color resist only allows blue light to pass through, while blocking other light wavelengths.

[0049] In this embodiment, both the blocking portion 222 and the first transmitting portion 212 are color resist materials. Specifically, if the first primary color visible light is red light, then the first transmitting portion 212 is a red color resist, and the blocking portion 222 can be a green color resist, a blue color resist, or a color resist of another color. If the first primary color visible light is green light, then the first transmitting portion 212 is a green color resist, and the blocking portion 222 can be a red color resist, a blue color resist, or a color resist of another color. If the first primary color visible light is blue light, then the first transmitting portion 212 is a blue color resist, and the blocking portion 222 can be a red color resist, a green color resist, or a color resist of another color. Furthermore, the first transmitting portion 212 and the blocking portion 222 can be disposed in the same layer, so that both the first transmitting portion 212 and the blocking portion 222 can be prepared in the process of preparing the color resist, thereby simplifying the process steps. Of course, the first transmitting portion 212 and the blocking portion 222 can also be disposed in different layers, in which case the first transmitting portion 212 and the blocking portion 222 need to be prepared in different layer preparation processes.

[0050] Optionally, in another embodiment of this application, such as Figure 3 As shown, the first transparent portion 212 is a color resist material, and the blocking portion 222 is a light-blocking material. For example, the blocking portion 222 can be a black matrix (BM).

[0051] It is understandable that the transmittance portion corresponding to the light-emitting element of each light-emitting unit can be a color resist material. For example, the transmittance portion corresponding to the red light-emitting element in the red light-emitting unit is a red color resist, the transmittance portion corresponding to the green light-emitting element in the green light-emitting unit is a green color resist, and the transmittance portion corresponding to the blue light-emitting element in the blue light-emitting unit is a blue color resist. Adjacent color resists are usually isolated by a light-shielding material (such as a black matrix) to prevent light passing through adjacent color resists from mixing in appearance. In this embodiment, the first transmittance portion 212 is a color resist material, and the blocking portion 222 is a light-shielding material. Furthermore, the first transmittance portion 212 and the blocking portion 222 can be disposed in the same layer, thereby allowing the blocking portion 222 to be prepared in the same process as the light-shielding material between adjacent color resists, simplifying the process steps. Of course, the first transmittance portion 212 and the blocking portion 222 can also be disposed in different layers; in this case, an additional mask for the blocking portion 222 is required.

[0052] Optionally, in one embodiment of this application, such as Figure 4 As shown, the first light-emitting element 211 includes a first light-emitting chip 2111, and the second light-emitting element 221 includes a second light-emitting chip 2211. Both the first light-emitting chip 2111 and the second light-emitting chip 2211 directly emit the first primary color visible light.

[0053] In this embodiment, both the first light-emitting chip 2111 and the second light-emitting chip 2211 directly emit the first primary color visible light, that is, both the first light-emitting element 211 and the second light-emitting element 221 are light-emitting elements for direct display.

[0054] We know that micro-LEDs are considered the best choice for achieving high-resolution and wide-color-gamut displays, as they feature low power consumption, fast response, long lifespan, and high luminous efficiency. However, currently, Micro-LED display panels do not have privacy protection features. In this embodiment, both the first light-emitting chip 2111 and the second light-emitting chip 2211 can be Micro-LEDs, meaning that the display panel provided in this embodiment can be a Micro-LED display panel with privacy protection features.

[0055] Optionally, in another embodiment of this application, such as Figures 1-3 As shown, the first light-emitting element 211 includes a first light-emitting chip 2111 and a first light conversion part 2112 located on the side of the first light-emitting chip 2111 facing away from the array substrate. The first light conversion part 2112 is used to convert the light emitted by the first light-emitting chip 2111 into first primary color visible light.

[0056] The second light-emitting element 221 includes a second light-emitting chip 2211 and a second light conversion part 2212 located on the side of the second light-emitting chip 2211 away from the array substrate. The second light conversion part 2212 is used to convert the light emitted by the second light-emitting chip 2211 into first primary color visible light.

[0057] The first light conversion unit 2112 and the second light conversion unit 2212 are arranged on the same layer.

[0058] Optional, such as Figures 1-3 As shown, both the first light-emitting chip 2111 and the second light-emitting chip 2211 are excitation light sources, both the first light conversion unit 2112 and the second light conversion unit 2212 are made of quantum dot materials, and both the first light-emitting element 211 and the second light-emitting element 221 are quantum dot light-emitting elements. Specifically, for example, the first light-emitting chip 2111 is a blue LED or an ultraviolet LED. The light emitted by the first light-emitting chip 2111 is incident on the first light conversion unit 2112, exciting the quantum dot material in the first light conversion unit 2112 to convert the incident light into first primary color visible light, which is then emitted. Similarly, the second light-emitting chip 2211 is a blue LED or an ultraviolet LED. The light emitted by the second light-emitting chip 2211 is incident on the second light conversion unit 2212, exciting the quantum dot material in the second light conversion unit 2212 to convert the incident light into first primary color visible light, which is then emitted.

[0059] In this embodiment, the first light conversion unit 2112 and the second light conversion unit 2212 are disposed on the same layer, thereby simplifying the film layer structure of the display panel.

[0060] Furthermore, in this embodiment, both the first light-emitting chip 2111 and the second light-emitting chip 2211 can be Micro-LEDs, meaning that the display panel provided in this embodiment can be a Micro-LED display panel with privacy protection function.

[0061] Currently, the excitation sources for incident quantum dot materials mainly use blue LEDs and ultraviolet LEDs. For red and green primary colors, when using blue LEDs or ultraviolet LEDs as excitation sources, the emitted light from the excitation source needs to be incident on the quantum dot material for color conversion. However, for blue, when using blue LEDs as excitation sources, the emitted light from the excitation source can be emitted directly without the need for quantum dot material. When using ultraviolet LEDs as excitation sources, the emitted light from the excitation source still needs to be incident on the quantum dot material for color conversion.

[0062] Accordingly, optionally, in one embodiment of this application, such as Figures 1-3 As shown, the light emitted by the first light-emitting chip 2111 is the same color as the light emitted by the second light-emitting chip 2211;

[0063] The first light conversion unit 2112 and the second light conversion unit 2212 are made of the same material.

[0064] In this embodiment, both the first light-emitting chip 2111 and the second light-emitting chip 2211 are blue LEDs or ultraviolet LEDs, and the first light conversion unit 2112 and the second light conversion unit 2212 are made of the same material. This ensures that the light emitted by the first light-emitting chip 2111 is converted into the first primary color visible light after being incident on the first light conversion unit 2112, and the light emitted by the second light-emitting chip 2211 is incident on the second light conversion unit 2212 and then emitted.

[0065] In this embodiment, both the first light-emitting element 211 and the second light-emitting element 221 are quantum dot light-emitting elements. When both the first light-emitting chip 2111 and the second light-emitting chip 2211 are blue LEDs, the light, after being converted by the first light conversion unit 2112 and the second light conversion unit 2212, can be converted into red or green light. When both the first light-emitting chip 2111 and the second light-emitting chip 2211 are ultraviolet LEDs, the first primary color visible light can be blue light, or of course, it can be red light, green light, or other colors.

[0066] Optionally, in another embodiment of this application, the light emitted by the first light-emitting chip 2111 and the light emitted by the second light-emitting chip 2211 may be different. That is, the first light-emitting chip 2111 is a blue LED and the second light-emitting chip 2211 is an ultraviolet LED, or the first light-emitting chip 2111 is an ultraviolet LED and the second light-emitting chip 2211 is a blue LED. In this case, in order to convert them into the first primary color visible light, the materials of the first light conversion part 2112 and the second light conversion part 2212 are also different.

[0067] Optionally, in yet another embodiment of this application, such as Figure 5 As shown, the first light-emitting element 211 includes a first light-emitting chip 2111 and a first transparent adhesive portion 2113 located on the side of the first light-emitting chip 2111 facing away from the array substrate. The first transparent adhesive portion 2113 allows light emitted by the first light-emitting chip 2111 to pass through.

[0068] The second light-emitting element 221 includes a second light-emitting chip 2211 and a second transparent adhesive portion 2213 located on the side of the second light-emitting chip 2211 facing away from the array substrate. The second transparent adhesive portion 2213 allows light emitted by the second light-emitting chip 2211 to pass through.

[0069] Both the first light-emitting chip 2111 and the second light-emitting chip 2211 directly emit the first primary color visible light, and the first transparent adhesive portion 2113 and the second transparent adhesive portion 2213 are disposed in the same layer.

[0070] In this embodiment, both the first light-emitting chip 2111 and the second light-emitting chip 2211 can be blue LEDs. The first transparent adhesive portion 2113 and the second transparent adhesive portion 2213 directly transmit blue light without the need for color conversion using quantum dot materials. At this time, other light-emitting elements can still be quantum dot light-emitting elements. Of course, they can also be light-emitting elements that emit primary color light directly without color conversion, depending on the specific situation.

[0071] In this embodiment, scattering particles can be added to the first transparent adhesive portion 2113 to change the emission angle of the light emitted by the first light-emitting chip 2111 and improve light utilization. Similarly, scattering particles can also be added to the second transparent adhesive portion 2213 to change the emission angle of the light emitted by the second light-emitting chip 2211 and improve light utilization.

[0072] In this embodiment, the first transparent adhesive portion 2113 and the second transparent adhesive portion 2213 are disposed in the same layer, thereby simplifying the display panel film layer structure and simplifying the process steps.

[0073] Optionally, in other embodiments of this application, the first light-emitting element 211 may be a quantum dot light-emitting element, and the second light-emitting element 221 may be a light-emitting element that directly emits primary color light, or the first light-emitting element 211 may be a light-emitting element that directly emits primary color light, and the second light-emitting element 221 may be a quantum dot light-emitting element, depending on the specific circumstances.

[0074] Optionally, in one embodiment of this application, reference is made to... Figures 1-5 As shown, the orthographic projection of the first light-emitting element 211 onto the plane of the array substrate is located within the orthographic projection range of the first transmission portion 212 onto the plane of the array substrate, and the orthographic projection of the second light-emitting element 221 onto the plane of the array substrate is located within the orthographic projection range of the blocking portion 222 onto the plane of the array substrate. Thus, the first primary color visible light emitted by the first light-emitting element 211 at a frontal viewing angle can be fully transmitted through the first transmission portion 212, and the first primary color visible light emitted by the second light-emitting element 221 at a side viewing angle can also be transmitted through the first transmission portion 212. At the same time, the first primary color visible light emitted by the second light-emitting element 221 at a frontal viewing angle can be fully blocked by the blocking portion 222, thereby better realizing the privacy protection function.

[0075] It should be noted that if the first light-emitting element 211 is a quantum dot light-emitting element, then the first light-emitting element 211 includes a first light-emitting chip 2111 and a first light conversion part 2112 located on the side of the first light-emitting chip 2111 facing away from the array substrate. In this case, the orthographic projection of the first light-emitting element 211 onto the plane of the array substrate is the sum of the orthographic projections of the first light-emitting chip 2111 and the first light conversion part 2112 onto the plane of the array substrate. If the first light-emitting element 211 is a light-emitting element that directly emits primary color light, then the first light-emitting element 211 may only include... The first light-emitting element 211 includes a first light-emitting chip 2111. In this case, the orthographic projection of the first light-emitting element 211 onto the plane of the array substrate is the same as the orthographic projection of the first light-emitting chip 2111 onto the plane of the array substrate. Alternatively, the first light-emitting element 211 may include the first light-emitting chip 2111 and a first transparent adhesive portion 2113 located on the side of the first light-emitting chip 2111 facing away from the array substrate. In this case, the orthographic projection of the first light-emitting element 211 onto the plane of the array substrate is the sum of the orthographic projections of the first light-emitting chip 2111 and the first transparent adhesive portion 2113 onto the plane of the array substrate. Similarly, there are three possible orthographic projections of the second light-emitting element 221 onto the plane of the array substrate, which will not be elaborated here.

[0076] It is understandable that by setting the orthographic projection area of ​​the first transmitting portion 212 on the plane of the array substrate and the orthographic projection area of ​​the blocking portion 222 on the plane of the array substrate, the angle at which the first primary color visible light emitted by the second light-emitting element 221 passes through the first transmitting portion 212 can be adjusted, thereby adjusting the privacy angle. For example, the larger the orthographic projection area of ​​the blocking portion 222 on the plane of the array substrate, the more oblique the angle of the light emitted by the second light-emitting element 221 that can pass through the first transmitting portion 212. The larger the angle at which the display panel is viewed from the side, the more interference it will cause, i.e., the larger the privacy angle. The specific angle can be determined according to actual needs.

[0077] It is also understandable that, reference Figures 1-5 As shown, there may be other film layers between the first light-emitting element 211 and the first transparent portion 212, and between the second light-emitting element 221 and the blocking portion 222. When the first transparent portion 212 and the blocking portion 222 are arranged in the same layer, the distance between the second light-emitting element 221 and the blocking portion 222, that is, the distance between the first light-emitting element 211 and the first transparent portion 212, will also affect the privacy angle. For example, the smaller the distance between the second light-emitting element 221 and the blocking portion 222, the larger the privacy angle. The specific distance can be determined according to actual needs.

[0078] As previously known, when the blocking portion 222 and the first transparent portion 212 are disposed in the same layer and are both made of color resist material, not only can the film layer structure of the display panel be simplified, but both the first transparent portion 212 and the blocking portion 222 can be prepared in the process of preparing color resist, thereby simplifying the process steps. Based on this, optionally, in one embodiment of this application, such as... Figure 6 As shown, the plurality of light-emitting units 20 also include multiple rows of light-emitting units extending along the first direction X and arranged along the second direction Y, wherein the first direction X and the second direction Y are perpendicular.

[0079] The multi-row light-emitting unit includes a first row light-emitting unit P1 and a second row light-emitting unit P2. The first light-emitting unit 21 and the second light-emitting unit 22 located in the first row light-emitting unit P1 are arranged adjacent to each other along the first direction X. The first light-emitting unit 21 and the second light-emitting unit 22 located in the second row light-emitting unit P2 are arranged adjacent to each other along the first direction X.

[0080] In the first row of light-emitting units P1, the second light-emitting unit 22 is located on one side of the first light-emitting unit 21 along the first direction X;

[0081] In the second row of light-emitting units P2, the second light-emitting unit 22 is located on the other side of the first light-emitting unit 21 along the first direction X.

[0082] For ease of understanding, Figure 7 This diagram shows a cross-sectional view of some of the light-emitting units in the first row of light-emitting units P1. Figure 6and Figure 7 As shown, in the first row of light-emitting units P1, the second light-emitting unit 22 is located on one side of the first light-emitting unit 21 along the first direction X. For example, the second light-emitting unit 22 is located on the right side of the first light-emitting unit 21 along the first direction X, so that the side-view light emitted by the second light-emitting element 221 in the second light-emitting unit 22, which is biased to the left side along the first direction X, passes through the first transmission part 212 in the first light-emitting unit 21, thereby realizing the side-view privacy protection of the display panel biased to the left side along the first direction X.

[0083] Similarly, Figure 8 This diagram shows a cross-sectional view of some of the light-emitting units in the second row of light-emitting units P2. Figure 6 and Figure 8 As shown, in the second row of light-emitting units P2, the second light-emitting unit 22 is located on the other side of the first light-emitting unit 21 along the first direction X. For example, the second light-emitting unit 22 is located on the left side of the first light-emitting unit 21 along the first direction X, so that the side-view light emitted by the second light-emitting element 221 in the second light-emitting unit 22, which is biased to the right side along the first direction X, passes through the first transmission part 212 in the first light-emitting unit 21, thereby realizing the side-view privacy protection of the display panel biased to the right side along the first direction X.

[0084] In this embodiment, by setting the second light-emitting unit 22 in the first row of light-emitting units P1 to one side of the first light-emitting unit 21 along the first direction X, and setting the second light-emitting unit 22 in the second row of light-emitting units P2 to the other side of the first light-emitting unit 21 along the first direction X, the side viewing angle privacy of the display panel along the left and right sides of the first direction X is achieved.

[0085] It should be noted that this application does not limit the arrangement of the first row of light-emitting units P1 and the second row of light-emitting units P2 along the second direction Y. Optionally, the first row of light-emitting units P1 and the second row of light-emitting units P2 can be arranged alternately along the second direction Y, thereby making the side viewing angle privacy effect of the display panel along the first direction X equally effective. Alternatively, the first row of light-emitting units P1 and the second row of light-emitting units P2 can also be arranged alternately along the second direction Y, that is, the first row of light-emitting units P1 can be arranged in several rows along the second direction Y, and then the second row of light-emitting units P2 can be arranged along the second direction, and so on. Of course, the first row of light-emitting units P1 and the second row of light-emitting units P2 can also have other arrangements along the second direction Y, as long as they can achieve side viewing angle privacy of the display panel along the first direction X.

[0086] It should also be noted that, in addition to the first row of light-emitting units P1 and the second row of light-emitting units P2, the multi-row light-emitting units may also include multi-row light-emitting units without the second light-emitting unit 22 (i.e., privacy unit). The row of light-emitting units without the second light-emitting unit 22 (i.e., privacy unit) may be arranged adjacent to the first row of light-emitting units P1 along the second direction Y, or adjacent to the second row of light-emitting units P2 along the second direction Y, or both adjacent to the first row of light-emitting units P1 and the second row of light-emitting units P2 along the second direction Y. This is to use the emitted light from the first row of light-emitting units P1 and / or the second row of light-emitting units P2 in the side view to interfere with the display effect of the row of light-emitting units without the second light-emitting unit 22 (i.e., privacy unit) in the side view, so that the row of light-emitting units without the second light-emitting unit 22 (i.e., privacy unit) can also achieve the purpose of privacy protection.

[0087] To further improve the privacy protection effect of the display panel on both sides along the first direction X, optionally, in one embodiment of this application, such as Figures 6-8 As shown, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the integral unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X.

[0088] In this embodiment, in the first row of light-emitting units P1, the first light-emitting unit 21 and the second light-emitting unit 22 are arranged adjacent to each other along the first direction X, and the overall unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X. In each overall unit, the second light-emitting unit 22 is located on the same side of the first light-emitting unit 21 along the first direction X, such as the right side. That is to say, the first row of light-emitting units P1 can emit side-view light from the same side, such as the left side, at multiple positions along the first direction X to interfere with the display and improve the privacy protection effect.

[0089] Similarly, in the second row of light-emitting units P2, the first light-emitting unit 21 and the second light-emitting unit 22 are arranged adjacent to each other along the first direction X, and the overall unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X. In each overall unit, the second light-emitting unit 22 is located on the same side of the first light-emitting unit 21 along the first direction X, such as the left side. That is to say, the second row of light-emitting units P1 can emit side-view light from the same side, such as the right side, at multiple positions along the first direction X to interfere with side peeping and improve the anti-peeping effect.

[0090] Further, optionally, in one embodiment of this application, such as Figures 6-8 As shown, each row of light-emitting units 20 includes a plurality of pixel units Px arranged along the first direction X. The pixel unit Px includes a first light-emitting unit 21, and also includes a third light-emitting unit 23 and a fourth light-emitting unit 24.

[0091] The third light-emitting unit 23 includes a third light-emitting element 231 and a second transmission portion 232 located on the side of the third light-emitting element 231 facing away from the array substrate. The third light-emitting element 231 is used to emit second primary color visible light, and the second transmission portion 232 allows the second primary color visible light to pass through.

[0092] The fourth light-emitting unit 24 includes a fourth light-emitting element 241 and a third transmission portion 242 located on the side of the fourth light-emitting element 241 facing away from the array substrate. The fourth light-emitting element 242 is used to emit third primary color visible light, and the third transmission portion 242 allows the third primary color visible light to pass through.

[0093] In each row of light-emitting units, pixel units Px and second light-emitting units 22 are arranged alternately and cyclically along the first direction X.

[0094] In each row of light-emitting units, the second light-emitting unit 22 is located between two adjacent pixel units Px along the first direction X. This ensures that the second light-emitting element 221 in the second light-emitting unit 22 is off. When the display panel is in normal display mode, the first light-emitting unit 21, the third light-emitting unit 23, and the fourth light-emitting unit 24 within each pixel unit Px are closely arranged to synthesize the color light to be displayed by the pixel unit Px, thus avoiding the influence of the inactive second light-emitting unit 22 on the overall display of each pixel unit Px. Furthermore, since the second light-emitting unit 22 is located between two adjacent pixel units Px along the first direction X, it does not affect the arrangement of the three light-emitting units within the pixel unit Px, nor does it affect the arrangement of different pixel units Px. Therefore, the arrangement of the second light-emitting unit 22 is simple and easy to implement. In other embodiments of this application, the second light-emitting unit 22 may also be located inside the pixel unit Px, depending on the specific circumstances.

[0095] Furthermore, in this embodiment, the pixel unit Px includes a first light-emitting unit 21, a third light-emitting unit 23, and a fourth light-emitting unit 24. The first light-emitting unit 21, the third light-emitting unit 23, and the fourth light-emitting unit 24 have similar structures to the second light-emitting unit 22. All four types of light-emitting units include a light-emitting element and a transmissive portion (color resist) located on the side of the light-emitting element away from the array substrate. In particular, the transmissive portions (color resist) of these four types of light-emitting units can be disposed in the same layer, that is, the manufacturing process of these four types of light-emitting units can be the same, which is beneficial to greatly simplify the manufacturing process of the display panel.

[0096] In the aforementioned embodiments, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the overall unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X. Further, in this embodiment, in each row of light-emitting units, the pixel unit Px and the second light-emitting unit 22 are arranged alternately and cyclically along the first direction X. That is, in the first row of light-emitting units P1 and the second row of light-emitting units P2, for a second light-emitting unit 22, there is a pixel unit Px on each side along the first direction X. Furthermore, the second light-emitting unit 22 is adjacent to the first light-emitting unit 21 on one side along the first direction X, and can be adjacent to the third light-emitting unit 23 or the fourth light-emitting unit 24 on the other side along the first direction X.

[0097] Based on the above embodiments, optionally, in one embodiment of this application, such as Figures 6-8 As shown, the blocking portion 222, the second transparent portion 232, and the third transparent portion 242 are disposed in the same layer and are all made of color resist material. Optionally, the blocking portion 222 and the first transparent portion 212 are disposed in the same layer and are all made of color resist material, that is, the first transparent portion 212, the second transparent portion 232, the third transparent portion 242, and the blocking portion 222 are disposed in the same layer and are all made of color resist material.

[0098] Since the second transparent portion 232 acts as a color blocker, it only allows the second primary color visible light emitted by the third light-emitting element 231 to pass through, and blocks the first primary color visible light emitted by the first light-emitting element 211 and the second light-emitting element 221, the blocking portion 222 can be made of the same material as the second transparent portion 232, thereby blocking the first primary color visible light emitted by the second light-emitting element 221 at a positive viewing angle.

[0099] Similarly, the third transmission portion 242, acting as a color blocker, only allows the third primary color visible light emitted by the fourth light-emitting element 241 to pass through, while blocking the first primary color visible light emitted by the first light-emitting element 211 and the second light-emitting element 221. Therefore, the blocking portion 222 can be made of the same material as the third transmission portion 242, thereby blocking the first primary color visible light emitted by the second light-emitting element 221 at a positive viewing angle.

[0100] In this embodiment, the blocking part 222 can be made of the same material as the second transparent part 232, or the blocking part 222 can be made of the same material as the third transparent part 242. In this way, the entire color resist layer can be an arrangement and combination of the color resists of the three light-emitting units, which is convenient for process preparation.

[0101] In the foregoing embodiments, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the second light-emitting unit 22 is adjacent to the first light-emitting unit 21 on one side along the first direction X, and the second light-emitting unit 22 is adjacent to the third light-emitting unit 23 or the fourth light-emitting unit 24 on the other side along the first direction X. Taking the second light-emitting unit 22 being adjacent to the fourth light-emitting unit 24 on the other side along the first direction X as an example... Figures 6-8 As shown, at this time, the frontal viewing angle light emitted by the second light-emitting element 221 is blocked by the blocking part 222, and the side viewing angle light emitted by the second light-emitting element 221 towards the fourth light-emitting unit 24 is blocked by the fourth transmission part 242. Meanwhile, the side viewing angle light emitted by the second light-emitting element 221 towards the first light-emitting unit 21 is transmitted through the first transmission part 212. Thus, side viewing interference prevention of the display panel along the first direction X is achieved in a row of light-emitting units. In addition, the side viewing angle light emitted by the second light-emitting unit 22 along the same side of the first direction X can be superimposed in a row of light-emitting units to enhance the side viewing angle light and improve the anti-spy effect. Then, by using the arrangement of the first row of light-emitting units P1 and the second row of light-emitting units P2 along the second direction Y, side viewing interference prevention of the display panel along the left and right sides of the first direction X is achieved. This is simpler than simultaneously achieving side viewing interference prevention of the display panel along the first direction X in a row of light-emitting units, and the anti-spy effect will not be affected by crosstalk between the left viewing angle light emitted by one anti-spy unit and the right viewing angle light emitted by another anti-spy unit in a row of light-emitting units.

[0102] Similarly, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the situation is similar when the second light-emitting unit 22 is adjacent to the first light-emitting unit 21 on one side along the first direction X, and the second light-emitting unit 22 is adjacent to the third light-emitting unit 23 on the other side along the first direction X. This will not be elaborated here.

[0103] As previously known, the first row of light-emitting units P1 and the second row of light-emitting units P2 are arranged alternately along the second direction Y, making the side viewing angle privacy effect of the display panel on both sides along the first direction X quite similar. Based on this, optionally, in one embodiment of this application, such as... Figures 6-8 As shown, when the materials of the blocking part 222 and the second transmission part 232 are the same, the second light-emitting unit 22 in the first row of light-emitting units P1 and the third light-emitting unit 23 in the second row of light-emitting units P2 are arranged along the second direction Y, and the second light-emitting unit 22 in the second row of light-emitting units P2 and the third light-emitting unit 23 in the first row of light-emitting units P1 are arranged along the second direction. In the same row of light-emitting units, the side of the second light-emitting unit 22 that is away from the adjacent first light-emitting unit 21 is the fourth light-emitting unit 24.

[0104] At this time, as Figure 6 and Figure 7As shown, in the first row of light-emitting units P1, the overall unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X. The pixel unit Px and the second light-emitting unit 22 are arranged alternately cyclically along the first direction X. The side of the second light-emitting unit 22 that is away from the adjacent first light-emitting unit 21 is the fourth light-emitting unit 24. Then, in the first row of light-emitting units P1, the overall unit composed of the fourth light-emitting unit 24, the third light-emitting unit 23, the first light-emitting unit 21 and the second light-emitting unit 22 arranged sequentially along the first direction X is arranged cyclically along the first direction X.

[0105] Similarly, such as Figure 6 and Figure 8 As shown, in the second row of light-emitting units P2, the first light-emitting unit 21, the third light-emitting unit 23, the fourth light-emitting unit 24 and the second light-emitting unit 22 arranged sequentially along the first direction X are arranged in a cyclic manner along the first direction X.

[0106] As can be seen, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the arrangement order of the first light-emitting unit 21, the third light-emitting unit 23, and the fourth light-emitting unit 24 in the pixel unit Px along the first direction X is exactly opposite.

[0107] Thus, as Figure 6 As shown, when the second light-emitting unit 22 in the first row of light-emitting units P1 and the third light-emitting unit 23 in the second row of light-emitting units P2 are arranged along the second direction Y, and the second light-emitting unit 22 in the second row of light-emitting units P2 and the third light-emitting unit 23 in the first row of light-emitting units P1 are arranged along the second direction Y, then the first light-emitting unit 21 in the first row of light-emitting units P1 and the first light-emitting unit 21 in the second row of light-emitting units P2 are also arranged along the second direction Y, and the fourth light-emitting unit 24 in the first row of light-emitting units P1 and the fourth light-emitting unit 24 in the second row of light-emitting units P2 are also arranged along the second direction Y.

[0108] In other words, such as Figure 6 As shown, for the first row of light-emitting units P1 and the second row of light-emitting units P2, the first light-emitting unit 21 is arranged in the same column, the fourth light-emitting unit 24 is arranged in the same column, and the second light-emitting unit 22 and the third light-emitting unit 23 are arranged in the same column. Corresponding to the color resist layer, combined with... Figures 6-7 As shown, the first transparent portion 212 is arranged in the same row, the third transparent portion 242 is arranged in the same row, and the blocking portion 222 and the second transparent portion 232 (made of the same material) are also arranged in the same row, thereby making the color resists of the same color arranged in the same row, which greatly simplifies the manufacturing process of the color resist.

[0109] like Figures 9-11 As shown, where, Figure 10 It shows Figure 9 A cross-sectional view of some of the light-emitting units in the first row of light-emitting units P1. Figure 11 It shows Figure 9 A cross-sectional structural diagram of some light-emitting units in the second row of light-emitting units P2. When the blocking part 222 and the third transmitting part 242 are made of the same material, the second light-emitting unit 22 in the first row of light-emitting units P1 and the fourth light-emitting unit 24 in the second row of light-emitting units P2 are arranged along the second direction Y. The second light-emitting unit 22 in the second row of light-emitting units P2 and the fourth light-emitting unit 24 in the first row of light-emitting units P1 are arranged along the second direction Y. In the same row of light-emitting units, the side of the second light-emitting unit 22 that is away from the adjacent first light-emitting unit 21 is the third light-emitting unit 23.

[0110] At this time, as Figure 9 and Figure 10 As shown, in the first row of light-emitting units P1, the overall unit composed of the first light-emitting unit 21 and the second light-emitting unit 22 is arranged cyclically along the first direction X. The pixel unit Px and the second light-emitting unit 22 are arranged alternately along the first direction X. The side of the second light-emitting unit 22 that is away from the adjacent first light-emitting unit 21 is the third light-emitting unit 23. Then, in the first row of light-emitting units P1, the overall unit composed of the third light-emitting unit 23, the fourth light-emitting unit 24, the first light-emitting unit 21 and the second light-emitting unit 22 arranged sequentially along the first direction X is arranged cyclically along the first direction X.

[0111] Similarly, such as Figure 9 and Figure 11 As shown, in the second row of light-emitting units P2, the first light-emitting unit 21, the fourth light-emitting unit 24, the third light-emitting unit 23 and the second light-emitting unit 22 arranged sequentially along the first direction X are arranged in a cyclic manner along the first direction X.

[0112] As can be seen, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the arrangement order of the first light-emitting unit 21, the fourth light-emitting unit 24, and the third light-emitting unit 23 within the pixel unit Px is exactly the opposite.

[0113] Thus, as Figure 9 As shown, when the second light-emitting unit 22 in the first row of light-emitting units P1 and the fourth light-emitting unit 24 in the second row of light-emitting units P2 are arranged along the second direction Y, and the second light-emitting unit 22 in the second row of light-emitting units P2 and the fourth light-emitting unit 24 in the first row of light-emitting units P1 are arranged along the second direction Y, then the first light-emitting unit 21 in the first row of light-emitting units P1 and the first light-emitting unit 21 in the second row of light-emitting units P2 are also arranged along the second direction Y, and the third light-emitting unit 23 in the first row of light-emitting units P1 and the third light-emitting unit 23 in the second row of light-emitting units P2 are also arranged along the second direction Y.

[0114] In other words, such as Figure 9As shown, for the first row of light-emitting units P1 and the second row of light-emitting units P2, the first light-emitting unit 21 is arranged in the same column, the third light-emitting unit 23 is arranged in the same column, and the second light-emitting unit 22 and the fourth light-emitting unit 24 are arranged in the same column. Corresponding to the color resist layer, combined with... Figures 9-11 As shown, the first transparent portion 212 is arranged in the same row, the second transparent portion 232 is arranged in the same row, and the blocking portion 222 and the third transparent portion 242 (made of the same material) are also arranged in the same row, thereby making the color resists of the same color arranged in the same row, which greatly simplifies the manufacturing process of the color resist.

[0115] Combination Figure 9 and Figure 10 As shown, in the first row of light-emitting units P1, the second light-emitting unit 22 is located on one side of the first light-emitting unit 21 along the first direction X. For example, the second light-emitting unit 22 is located on the right side of the first light-emitting unit 21 along the first direction X, so that the side-view light emitted by the second light-emitting element 221 in the second light-emitting unit 22, which is biased to the left side along the first direction X, passes through the first transmission part 212 in the first light-emitting unit 21, thereby realizing the side-view privacy protection of the display panel biased to the left side along the first direction X.

[0116] Similarly, combining Figure 9 and Figure 11 As shown, in the second row of light-emitting units P2, the second light-emitting unit 22 is located on the other side of the first light-emitting unit 21 along the first direction X. For example, the second light-emitting unit 22 is located on the left side of the first light-emitting unit 21 along the first direction X, so that the side-view light emitted by the second light-emitting element 221 in the second light-emitting unit 22, which is biased to the right side along the first direction X, passes through the first transmission part 212 in the first light-emitting unit 21, thereby realizing the side-view privacy protection of the display panel biased to the right side along the first direction X.

[0117] As previously known, the first light-emitting element 211 in the first light-emitting unit 21 can be a light-emitting element that directly emits primary color light or a quantum dot light-emitting element; the second light-emitting element 221 in the second light-emitting unit 22 can be a light-emitting element that directly emits primary color light or a quantum dot light-emitting element. It should be noted that... Figures 6-12 The examples illustrate how both the first light-emitting element 211 and the second light-emitting element 221 are quantum dot light-emitting elements. The first light-emitting element 211 includes a first light-emitting chip 211 and a first light conversion part 2112 located on the side of the first light-emitting chip 211 away from the array substrate. The first light-emitting chip 211 can be a blue LED or an ultraviolet LED. The second light-emitting element 221 includes a second light-emitting chip 2211 and a second light conversion part 2212 located on the side of the second light-emitting chip 2211 away from the array substrate. The first light-emitting chip 221 can be a blue LED or an ultraviolet LED.

[0118] At this point, optional reference Figures 6-8 As shown, the first light-emitting unit 21 is a red light-emitting unit, the first transmission part 212 is a red color resist, the third light-emitting unit 23 is a blue light-emitting unit, the second transmission part 232 is a blue color resist, the fourth light-emitting unit 24 is a green light-emitting unit, and the third transmission part 242 is a green color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a blue color resist, which is made of the same material as the second transmission part 232.

[0119] Another option is to refer to Figures 9-11 As shown, the first light-emitting unit 21 is a red light-emitting unit, the first transmission part 212 is a red color resist, the third light-emitting unit 23 is a blue light-emitting unit, the second transmission part 232 is a blue color resist, the fourth light-emitting unit 24 is a green light-emitting unit, and the third transmission part 242 is a green color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a green color resist, which is made of the same material as the third transmission part 242.

[0120] Similarly, optional, see reference. Figures 6-8 As shown, the first light-emitting unit 21 is a green light-emitting unit, the first transparent part 212 is a green color resist, the third light-emitting unit 23 is a blue light-emitting unit, the second transparent part 232 is a blue color resist, the fourth light-emitting unit 24 is a red light-emitting unit, and the third transparent part 242 is a red color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a blue color resist, which is made of the same material as the second transparent part 232.

[0121] Another option is to refer to Figures 9-11 As shown, the first light-emitting unit 21 is a green light-emitting unit, the first transmission part 212 is a green color resist, the third light-emitting unit 23 is a blue light-emitting unit, the second transmission part 232 is a blue color resist, the fourth light-emitting unit 24 is a red light-emitting unit, and the third transmission part 242 is a red color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a red color resist, which is made of the same material as the third transmission part 242.

[0122] It should be noted that, in Figures 6-11 In this example, the third light-emitting unit 23 is a blue light-emitting unit, and the third light-emitting element 231 includes a third light-emitting chip 2311 and a third transparent adhesive portion 2313 located on the side of the third light-emitting chip 2311 facing away from the array substrate. In this case, the third light-emitting chip 2311 can be a blue LED, and the third transparent adhesive portion 2313 can be disposed on the same layer as the first light conversion unit 212 and the second light conversion unit 2212. Furthermore, scattering particles can be added to the third transparent adhesive portion 2313 to change the light emission direction and improve light utilization. It is understood that the third light-emitting element 231 can also include only the third light-emitting chip 2311, or it can include the third light-emitting chip 2311 and the third light conversion unit located on the side of the third light-emitting chip 2311 facing away from the array substrate; that is, the third light-emitting element 231 is a quantum dot light-emitting element.

[0123] exist Figures 6-11 In this example, the fourth light-emitting element 241 in the fourth light-emitting unit 24 is shown as a quantum dot light-emitting element. Specifically, the fourth light-emitting element 241 includes a fourth light-emitting chip 2411 and a fourth light conversion portion 2412 located on the side of the fourth light-emitting chip 2411 facing away from the array substrate. Of course, the fourth light-emitting element 24 can also be a light-emitting element that directly emits primary color light; that is, the fourth light-emitting element 24 may only include the fourth light-emitting chip 2411, or it may include the fourth light-emitting chip 2411 and a fourth transparent adhesive portion located on the side of the fourth light-emitting chip 2411 facing away from the array substrate.

[0124] Optional, such as Figure 12 As shown, the first light-emitting unit 21 is a blue light-emitting unit, the first transmission part 212 is a blue color resist, the third light-emitting unit 23 is a red light-emitting unit, the second transmission part 232 is a red color resist, the fourth light-emitting unit 24 is a green light-emitting unit, and the third transmission part 242 is a green color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a red color resist, which is made of the same material as the second transmission part 232.

[0125] Another option, such as Figure 13 As shown, the first light-emitting unit 21 is a blue light-emitting unit, the first transmission part 212 is a blue color resist, the third light-emitting unit 23 is a green light-emitting unit, the second transmission part 232 is a green color resist, the fourth light-emitting unit 24 is a red light-emitting unit, and the third transmission part 242 is a red color resist. Therefore, the blocking part 222 of the second light-emitting unit 22 can be a green color resist, which is made of the same material as the third transmission part 242.

[0126] It is understandable that if the first row of light-emitting units P1 is as follows: Figure 12 As shown in the diagram, the second row of light-emitting units P2 is as follows: Figure 13 The arrangement shown above indicates the color resist arrangement of the first row of light-emitting units P1 and the second row of light-emitting units P2 as follows: Figure 6 As shown, in the first row of light-emitting units P1 and the second row of light-emitting units P2, the arrangement order of the first light-emitting unit 21, the third light-emitting unit 23, and the fourth light-emitting unit 24 in the pixel unit Px is exactly opposite along the first direction X.

[0127] It should be noted that, in Figure 12 and Figure 13In this example, the first light-emitting unit 21 is a blue light-emitting unit, and the first light-emitting element 211 includes a first light-emitting chip 2111 and a first transparent adhesive portion 2113 located on the side of the first light-emitting chip 2111 facing away from the array substrate. In this case, the second light-emitting element 221 in the second light-emitting unit 22 includes a second light-emitting chip 2211 and a second transparent adhesive portion 2213 located on the side of the second light-emitting chip 2211 facing away from the array substrate. Both the first light-emitting chip 2111 and the second light-emitting chip 2211 can be blue LEDs.

[0128] Optional, such as Figure 14 As shown, the blocking part 222 of the second light-emitting unit 22 can also be a light-shielding material, such as a black matrix.

[0129] It should also be noted that, in Figures 6-14 In this example, we'll use blue LEDs as an example where all light-emitting elements are quantum dot light-emitting elements, and the light-emitting chips in each element are ultraviolet LEDs. It's conceivable that when all light-emitting elements are quantum dot light-emitting elements, and the light-emitting chips in each element are ultraviolet LEDs, the effect would be different. Figures 6-11 The arrangement of each light-emitting unit is similar, so it will not be described again here.
