Description

Technical Field

[0001] The present application relates to the field of display devices, and more particularly, to a display panel and a display apparatus. Background Art

[0002] Display panels are widely used in mobile phones, computers, televisions and other fields. Currently, common display panels include organic light-emitting diode (OLED) display panels and liquid crystal display panels. With the development and progress of technology, the market's requirements for display panels are constantly increasing. In some usage scenarios, such as in-vehicle scenarios, the demand for multi-viewing display panels or multi-viewing display screens has emerged, that is, the picture can only be observed at specific multiple viewing angles, while the picture cannot be observed at other viewing angles, which has an anti-peeping effect.

[0003] In view of this, how to provide a multi-viewing angle display screen with better performance is an issue that needs to be solved urgently. Summary of the invention

[0004] The present application provides a display panel and a display device, which can provide a multi-viewing angle display screen with better performance.

[0005] In a first aspect, a display panel is provided, comprising: a pixel layer, comprising a first pixel and a second pixel; an isolation column layer, comprising a first isolation column, the first isolation column being located between the first pixel and the second pixel; a light-shielding layer, the light-shielding layer being located above the isolation column layer and the pixel layer, comprising a first light-shielding area, a first light-transmitting hole and a second light-transmitting hole, the first light-shielding area being located between the first light-transmitting hole and the second light-transmitting hole, and an orthographic projection of the first isolation column on the pixel layer being located in an orthographic projection of the first light-shielding area on the pixel layer; wherein the first light-transmitting hole is used to pass a light signal within a first angle range emitted by the first pixel, the second light-transmitting hole is used to pass a light signal within a second angle range emitted by the second pixel, and the first isolation column is used to block a light signal emitted by the first pixel toward the second light-transmitting hole, and to block a light signal emitted by the second pixel toward the first light-transmitting hole.

[0006] The technical solution provided by the present application introduces isolation columns in the laminated structure of the display panel. Through the combination of the shading layer and the isolation columns, the light of different pixels is controlled to be emitted through their corresponding light-transmitting holes, thereby reducing or even preventing light interference between adjacent pixels, so as to effectively control the pixel light-emitting angle range, so as to realize the display panel to emit light emitted by specific pixels at a specific angle, thereby realizing multi-angle display of the display panel, and further facilitating the display panel to display different pictures at different angles, as well as the anti-peeping effect at other angles other than the display angle.

[0007] In combination with the first aspect, in some possible implementations, in a direction parallel to the pixel layer, the size of the first pixel is greater than or equal to the size of the first light-transmitting hole, and / or the size of the second pixel is greater than or equal to the size of the second light-transmitting hole.

[0008] The technical solution provided by the present application is to design the pixel size to be larger than the corresponding light-transmitting hole size, which is conducive to forming some preferred target viewing angles. Within these target viewing angles, the pixel display width is large and the display effect is good. When the pixel size is further increased compared to the light-transmitting hole size, the preferred target viewing angle range will also increase accordingly, so that the display panel has a better display effect at a larger angle.

[0009] In combination with the first aspect, in some possible implementations, in a direction parallel to the pixel layer, the sizes of the first pixel and the second pixel are equal or unequal.

[0010] In this way, the display effects of the two pixels can be adjusted. When the sizes of the first pixel and the second pixel are equal, the display images of the panel at different viewing angles are symmetrical, and the display effects are also relatively balanced. In addition, the design of pixels of the same size is also convenient for hardware design and implementation, which is beneficial to reducing the manufacturing cost of the display panel. When the sizes of the first pixel and the second pixel are not equal, for example, when the size of the first pixel is larger than the size of the second pixel, the light emitted by the first pixel through the first light-transmitting hole is more than the light emitted by the second pixel through the second light-transmitting hole, and the display effect of the first pixel is better than that of the second pixel, and the display effects of the two pixels can be adjusted with emphasis.

[0011] In combination with the first aspect, in some possible implementations, the first pixel and the second pixel are located in the orthographic projection of the first light-shielding area on the pixel layer.

[0012] In this way, mutual interference between the first pixel and the second pixel at an angle perpendicular to the display panel and outward can be reduced.

[0013] In combination with the first aspect, in some possible implementations, the size W1 of the first pixel, the size W2 of the second pixel, and the size W of the first isolation column are S1 , the minimum distance W between the first light-transmitting hole and the first isolation column S1H1 , the minimum distance W between the second light-transmitting hole and the first isolation column S1H2 , the height h1 of the first isolation column, and the distance H between the light shielding layer and the pixel layer have the following relationship:

[0014] h1×(W1+W S1 +W S1H2 )≥H×W1;

[0015] h1×(W2+W S1 +W S1H1)≥H×W2;

[0016] Among them, W1, W2, W S1 , W S1H1 and W S2H2 is the dimension in the direction parallel to the pixel layer, and h1 and H are the dimensions in the direction perpendicular to the pixel layer.

[0017] In this way, the viewing angle of each pixel can be reduced, and the mutual interference between the light emitted by the pixels can be reduced. In this way, the display effect of the display panel at different angles can be improved, and the pictures of different pixels can have a certain anti-peeping screen effect, and this size relationship can facilitate the design of the display panel.

[0018] In combination with the first aspect, in some possible implementations, the isolation column layer also includes a second isolation column, and the light-shielding layer also includes a third light-transmitting hole and a second light-shielding area; wherein the second isolation column is located on the left side of the first pixel, and the orthographic projection of the second isolation column on the pixel layer is located in the orthographic projection of the second light-shielding area on the pixel layer, and the second isolation column is used to block the light signal emitted by the first pixel toward the third light-transmitting hole.

[0019] In this way, the light of the first pixel can be adjusted to be emitted in a direction perpendicular to the outward direction of the display panel, so that the display angle of the first pixel can be adjusted more conveniently, and the display effect of the panel can be improved.

[0020] In combination with the first aspect, in some possible implementations, the pixel layer also includes a third pixel, the isolation column layer also includes a second isolation column, the light shading layer also includes a third light-transmitting hole and a second light-shielding area, and the second light-shielding area is located between the first light-transmitting hole and the third light-transmitting hole; wherein the second isolation column is located between the first pixel and the third pixel, the orthographic projection of the second isolation column on the pixel layer is located in the orthographic projection of the second light-shielding area on the pixel layer, the third light-transmitting hole is used to pass the light signal of the third angle emitted by the third pixel, and the second isolation column is used to block the light signal emitted by the first pixel toward the third light-transmitting hole, and block the light signal emitted by the third pixel toward the first light-transmitting hole.

[0021] In this way, the display panel can emit light of different pixels in three directions respectively, so as to realize three-viewing angle display, and the three viewing angles do not interfere with each other. Except for the three viewing angles, there is no display image at other viewing angles, which has a better anti-peeping effect.

[0022] In combination with the first aspect, in some possible implementations, the first pixel is located directly below the first light transmission hole.

[0023] In this way, the light emitted by the first pixel can be emitted in a direction perpendicular to the display panel, that is, the visible angle of the first pixel can be adjusted to a normal viewing angle.

[0024] In combination with the first aspect, in some possible implementations, in a direction parallel to the pixel layer, the size of the first pixel is greater than or equal to the size of the second pixel, and / or the size of the first pixel is greater than or equal to the size of the third pixel.

[0025] In this way, the viewing angle of the first pixel can be increased, and the display effect of the first pixel display can be enhanced.

[0026] In combination with the first aspect, in some possible implementations, in a direction parallel to the pixel layer, a size of the third pixel is greater than or equal to a size of the third light transmission hole.

[0027] In this way, the display effect of the first pixel can be improved.

[0028] In combination with the first aspect, in some possible implementations, in a direction parallel to the pixel layer, the sizes of the second pixel and the third pixel are equal or unequal.

[0029] In this way, the display effects of the second pixel and the third pixel can be adjusted. When the sizes of the second pixel and the third pixel are equal, the display images of the panel at the left and right viewing angles are symmetrical, and the display effect is also relatively balanced. In addition, the design of pixels of the same size is also convenient for hardware design and implementation, which is conducive to reducing the manufacturing cost of the display panel. When the sizes of the second pixel and the third pixel are not equal, for example, when the size of the second pixel is larger than the size of the third pixel, the light emitted by the second pixel through the second light-transmitting hole is more than the light emitted by the third pixel through the third light-transmitting hole, and the display effect of the second pixel is better than that of the third pixel, and the display effects of the two pixels can be adjusted with emphasis.

[0030] In combination with the first aspect, in some possible implementations, the third pixel is located in the orthographic projection of the second light-shielding area on the pixel layer.

[0031] In this way, the light emitted by the third pixel is difficult to be emitted outward at an angle perpendicular to the display panel, which can reduce the interference between the light emitted by the third pixel and the light emitted by the first pixel, thereby improving the display effect.

[0032] In combination with the first aspect, in some possible implementations, the size W1 of the first pixel, the size W3 of the third pixel, the width W of the second isolation column S2 , the minimum distance W between the first light-transmitting hole and the second isolation column S2H1 , the minimum distance W between the third light-transmitting hole and the second isolation column S2H3 , the height h2 of the second isolation column, and the distance H between the light shielding layer and the pixel layer have the following relationship:

[0033] h2×(W1+W S2 +W S2H3 )≥H×W1;

[0034] h2×(W3+W S2 +W S2H1 )≥H×W3;

[0035] Among them, W1, W3, W S2 , W S2H1 and W S2H3 is the dimension in the direction parallel to the pixel layer, h2 and H are the dimensions in the direction perpendicular to the pixel layer.

[0036] In this way, the viewing angles of the first pixel and the third pixel can be reduced, the mutual interference between the light emitted by the first pixel and the third pixel can be reduced, the display effect of the display panel at the corresponding angles of the first pixel and the third pixel can be improved, and the images of the first pixel and the third pixel can have a certain anti-peeping screen effect respectively, and this size relationship can facilitate the design of the display panel.

[0037] In combination with the first aspect, in some possible implementations, the display panel includes pixels of multiple colors, and the n pixels in each group of pixels have the same color, or at least some of the n pixels in each group of pixels have different colors.

[0038] Through this implementation, pixels for displaying the same picture are set at the same position in each group of pixels, which is beneficial to hardware design and also convenient for subsequent testing and positioning of display performance.

[0039] In combination with the first aspect, in some possible implementations, the display panel includes pixels of multiple colors, and the colors of n pixels in each group of pixels are the same or the colors of at least some of the pixels are different.

[0040] In this way, each picture of the display panel can have rich colors.

[0041] In combination with the first aspect, in some possible implementations, the height of the isolation column is lower than the distance between the light shielding layer and the pixel layer.

[0042] In this way, the isolation layer and the light shielding layer do not abut against each other, and when the display panel is manufactured and packaged, the packaging layer has a better sealing effect on the pixel layer.

[0043] In combination with the first aspect, in some possible implementations, the first pixel includes a first filter and a first pixel circuit, the first filter is located above the first pixel circuit, and the first pixel circuit is used to control the first pixel to display a first picture; the second pixel includes a second filter and a second pixel circuit, the second filter is located above the second pixel circuit, and the second pixel circuit is used to control the second pixel to display a second picture; wherein the first pixel circuit and the second pixel circuit are independently controlled.

[0044] In this way, different screens can be controlled independently.

[0045] In a second aspect, a method for manufacturing a display panel is provided, comprising: preparing a pixel layer, the pixel layer comprising a first pixel and a second pixel; preparing an isolation column layer, the isolation column layer comprising a first isolation column, the first isolation column being located between the first pixel and the second pixel; preparing a light-shielding layer, the light-shielding layer being located above the isolation column layer, comprising a first light-shielding area, a first light-transmitting hole, and a second light-transmitting hole, the orthographic projection of the first isolation column on the pixel layer being located in the orthographic projection of the first light-shielding area on the pixel layer; wherein the first light-transmitting hole is used to pass a light signal of a first angle emitted by the first pixel, the second light-transmitting hole is used to pass a light signal of a second angle emitted by the second pixel, and the first isolation column is used to block the light signal emitted by the first pixel toward the second light-transmitting hole, and block the light signal emitted by the second pixel toward the first light-transmitting hole.

[0046] In combination with the second aspect, in some possible implementations, the first pixel includes: a first pixel circuit and a first filter element, and the second pixel includes: a second pixel circuit and a second filter element; wherein, preparing the pixel layer includes: preparing a pixel circuit backplane, the pixel circuit backplane includes the first pixel circuit and the second pixel circuit; preparing a pixel definition layer, the pixel definition layer includes a first pixel definition area located at the overall periphery of the first pixel circuit and the second pixel circuit; preparing the isolation column layer includes: preparing a first isolation column between the first pixel circuit and the second pixel circuit; preparing the pixel layer also includes: preparing a filter layer, the filter layer includes a first filter element located above the first pixel circuit and a second filter element located above the second pixel circuit, and the isolation column layer is used as a support structure for preparing a fine metal mask for the filter layer.

[0047] A display panel including an isolation column layer can be manufactured. The display panel can display multiple images on one display panel, and can control the viewing angle of the display panel to reduce screen peeking.

[0048] In combination with the second aspect, in some possible implementations, the filter layer includes three colors: red, blue, and green.

[0049] In combination with the second aspect, in some possible implementations, the filter layer is manufactured by an evaporation process.

[0050] In combination with the second aspect, in some possible implementations, the filter layer includes multiple colors and is manufactured by an evaporation process, and only one color of the filter layer is evaporated in each evaporation step.

[0051] In combination with the second aspect, in some possible implementations, the filter layer is evaporated by a fine metal mask process.

[0052] In combination with the second aspect, in some possible implementations, the encapsulation layer is located above the pixel layer and the isolation column layer, and covers the isolation column layer.

[0053] In this way, the sealing degree around the isolation column layer can be improved.

[0054] In combination with the second aspect, in some possible implementations, a flat protective layer is prepared above the encapsulation layer and the light shielding layer.

[0055] In this way, the light shielding layer can be protected and the service life of the display panel can be increased.

[0056] In combination with the second aspect, in some possible implementations, the pixel definition layer and the isolation column layer are black photoresist materials, and the isolation column layer and the pixel definition layer are prepared in one step through a halftone process; or, the material of the pixel definition layer includes at least one of the following materials: transparent photoresist or black photoresist; the material of the isolation column layer includes at least one of the following materials: black photoresist, metal or metal-plated transparent photoresist surface, and the pixel definition layer and the isolation column layer are prepared through a two-step process.

Alternatively, the pixel definition layer and the isolation column layer can be manufactured using different materials or a combination of materials, and different materials can be selected to prepare light-shielding layers with different costs or performances.

[0080] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0081] In the present application, the methods, situations, categories and divisions of the embodiments in each application embodiment are only for the convenience of description and should not constitute special limitations. The features of various methods, categories, situations and embodiments can be combined without contradiction.

The "multiple" in the application embodiments refers to two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0083] It should also be understood that in the various embodiments of the present application, the size of the serial number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0084] It should also be understood that the directions or positional relationships indicated by the terms "upper" and "lower" are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the "in the direction of..." involved in the present application does not mean along a certain direction in a strict sense, "parallel" does not mean strictly parallel, and "perpendicular" does not mean strictly perpendicular, and the above directions can be within the allowable error range.

[0085] The present application relates to a display screen or a display device. The display screen can be applied to a variety of fields and scenarios. For example, the display screen can be applied to various types of electronic products, including but not limited to televisions, mobile phones, computers, laptops, tablet computers, personal digital assistants (PDAs), vehicle-mounted devices, wearable devices, gaming devices, shooting devices, billboards, art screen devices, etc. The present application does not limit the specific type of electronic device where the display screen is located.

[0086] In addition, the display screen involved in the present application may be a liquid crystal display (LCD) or an organic light emitting diode (OLED) display screen, a low temperature polycrystalline silicon (LTPS) OLED display screen, an oxide OLED display screen, a micro OLED display screen, etc. The present application does not limit the specific type of the display screen.

[0087] In some application scenarios such as in-vehicle, billboards, and art screens, there is a demand for multi-viewing display screens, that is, users can observe multiple images at specific multiple viewing angles, while other viewing angles cannot observe the images, thus achieving an anti-peeping effect. For this application scenario, the present application can provide a display panel with multiple viewing angles, which can be well applied to display screens to meet the viewing needs of multiple viewing angles.

[0088] Figure 1 A schematic diagram of the structure of a display panel 100 provided in an embodiment of the present application.

[0089] like Figure 1 As shown, the display panel 100 includes: a light shielding layer 110, a pixel layer 120 and an isolation column layer 130. The pixel layer 120 includes a first pixel 121 and a second pixel 122, the isolation column layer 130 includes a first isolation column 131, and the first isolation column 131 is located between the first pixel 121 and the second pixel 122. The light shielding layer 110 is located above the isolation column layer 130 and the pixel layer 120. The light shielding layer 110 includes a first light shielding region 113, a first light transmission hole 111 and a second light transmission hole 112. The first light shielding region 113 is located between the first light transmission hole 111 and the second light transmission hole 112, and the orthographic projection of the first isolation column 131 on the pixel layer 120 is located in the orthographic projection of the first light shielding region 113 on the pixel layer.

[0090] The light signal emitted by the first pixel 121 can pass through the first light-transmitting hole 111, and the light signal emitted by the second pixel 122 can pass through the second light-transmitting hole 112. However, due to the shielding of the first isolation column 131, the light emitted by the first pixel 121 cannot reach the second light-transmitting hole 112, and the light emitted by the second pixel 122 cannot reach the first light-transmitting hole 111. In other words, the first light-transmitting hole 111 can be used to pass the light signal of the first angle range θ1 emitted by the first pixel 121; the second light-transmitting hole 112 can be used to pass the light signal of the second angle range θ2 emitted by the second pixel 122, and the first isolation column 131 is used to block the light signal emitted by the first pixel 121 toward the second light-transmitting hole 112, and block the light signal emitted by the second pixel 122 toward the first light-transmitting hole 111.

[0091] The technical solution provided in this embodiment introduces isolation columns in the laminated structure of the display panel. Through the combination of the shading layer and the isolation columns, the light of different pixels is controlled to be emitted through the corresponding light-transmitting holes, reducing or even preventing the light interference between adjacent pixels, so as to effectively control the pixel light-emitting angle range, so as to realize the display panel to emit light emitted by specific pixels at a specific angle, thereby realizing multi-angle display of the display panel, and further facilitating the display panel to display different pictures at different angles, as well as the anti-peeping effect at other angles other than the display angle. In addition, the introduction of the isolation column is conducive to reducing the height of the shading layer, adjusting the pixel light-emitting angle, increasing the viewing angle, and widening the design space. Furthermore, the isolation column can also reduce the reflection, refraction, and scattering of light in the display panel, reduce light leakage, and improve the display effect.

[0092] It should be noted that the display panel provided in the embodiment of the present application may also include multiple groups such as Figure 1 The structure shown. The first pixel 121 and the second pixel 122 may be a group of pixels in the pixel layer 120. The first pixel and the second pixel may display the same picture or different pictures. The pixel layer may include an array composed of multiple groups of pixels. As an example, Figure 2 A schematic structural diagram of a display panel 200 including an array composed of multiple groups of pixels is shown.

[0093] like Figure 2 As shown, the pixel layer 201 of the display panel 200 includes three pixel groups: a first pixel group 210, a second pixel group 220 and a third pixel group 230, and the pixel groups are separated by a pixel definition layer 240. Pixel 211, pixel 221 and pixel 231 are respectively the first pixels in the three pixel groups, and pixel 212, pixel 222 and pixel 232 are respectively the second pixels in the three pixel groups. An isolation column is provided between the first pixel and the second pixel of each pixel group, and a plurality of isolation columns form an isolation column layer 203. Optionally, each pixel group can be respectively designed with its light-transmitting hole in the light-shielding layer 202. Alternatively, adjacent pixel groups can also share the light-transmitting hole in the light-shielding layer 202.

[0094] For example, Figure 2 As shown, the light emitted by the second pixel 212 of the first pixel group 210 and the first pixel 221 of the second pixel group 220 can be used to pass through the same light-transmitting hole, that is, the second pixel 212 of the first pixel group 210 and the first pixel 221 of the second pixel group 220 share the same light-transmitting hole. Similarly, the light emitted by the second pixel 222 of the second pixel group 220 and the first pixel 231 of the third pixel group 230 can also be used to pass through the same light-transmitting hole.

[0095] In the embodiment of the present application, each pixel in the display panel may include a pixel circuit and a filter. The pixel circuit is used to control the pixel to emit light, and the filter is used to make the pixel emit light of a specific color. As an example, Figure 2 The first pixel 211 of the first pixel group 210 may include a red filter 2111 and a first red pixel circuit 2112, the first pixel 221 of the second pixel group 220 may include a blue filter 2211 and a first blue pixel circuit 2212, and the first pixel 231 of the third pixel group 230 may include a green filter 2311 and a first green pixel circuit 2312. In this way, the three first pixels may form an imaging pixel group having three colors: red (Red, R), green (Green, G), and blue (Blue, B). The first red pixel circuit 2112, the first blue pixel circuit 2212, and the first green pixel circuit 2312 of the three first pixels may be independently controlled so that the imaging pixel group may emit a light signal in a first viewing angle range and be used to display a first picture. Similarly, the second pixel 212 of the first pixel group 210, the second pixel 222 of the second pixel group 220, and the second pixel 232 of the third pixel group 230 may also include a red filter 2121, a green filter 2221, a blue filter 2321, and three second pixel circuits, respectively. The second red pixel circuit 2122, the first blue pixel circuit 2222, and the first green pixel circuit 2322 of the three second pixels may be independently controlled, so that another display pixel group composed of the three second pixels may emit a light signal in a second viewing angle range and be used to display a second picture. The first picture and the second picture may be the same or different pictures.

[0096] In the embodiment of the present application, when the pixel circuits of the plurality of pixels are independent of each other, each picture can be controlled independently. When the pixel circuits of the plurality of first pixels are independent of the pixel circuits of the plurality of second pixels, the independent pixel circuits can control the plurality of first pixels and the plurality of second pixels to emit light respectively, so that the two display pixel groups display the same or different pictures respectively, and realize independent control of the first picture and the second picture, that is, the first picture and the second picture can display the same or different pictures.

[0097] Optionally, in the above application embodiment, any viewing angle in the first viewing angle range is different from any viewing angle in the second viewing angle range.

[0098] Optionally, in the above-mentioned application embodiment, the light shielding layer may be made of black or other dark light absorbing materials, and the light shielding area in the light shielding layer is the area where the light absorbing material is provided, which is used to block the passage of light. The light-transmitting hole in the light shielding layer is the through hole formed in the light absorbing material, and the through hole may be circular or any other regular or irregular shape, which is not limited in the present application embodiment.

[0099] Optionally, the function of the isolation column in the isolation column layer is similar to that of the above-mentioned light shielding layer, and at least the surface of the isolation column is also provided with black or other dark light absorbing materials to block the passage of light. As an example but not a limitation, the material of the isolation column can be, for example, black photoresist, metal, transparent photoresist surface plated with metal, or other materials, etc., which is not limited in the embodiments of the present application.

[0100] In some implementations, in order to improve the light shielding effect of the isolation column layer, the size design of each stacked layer in the display panel of any of the above embodiments can meet certain design requirements. Figure 3 As shown, the light emitted by the first pixel 321 can reach the first light-transmitting hole 311, and is blocked by the first isolation column 331 and cannot reach the second light-transmitting hole 312; the light emitted by the second pixel 322 can reach the second light-transmitting hole 312, and is blocked by the first isolation column 331 and cannot reach the first light-transmitting hole 311. In order to achieve the above effect, Figure 3 The dimensions shown in satisfy the following relationships:

[0101] h1×(W1+W S1 +W S1H2 )≥H×W1(1)

[0102] h1×(W2+W S1 +W S1H1 )≥H×W2(2)

[0103] Wherein, h1 is the height of the first isolation column 331 (i.e., the size of the first isolation column 331 in a direction perpendicular to the pixel layer), W1 is the width of the first pixel 321 (i.e., the size of the first pixel 321 in a direction parallel to the pixel layer), W2 is the width of the second pixel 322 (i.e., the size of the second pixel 322 in a direction parallel to the pixel layer), and W S1 is the width of the first isolation column 331 (ie, the dimension of the first isolation column 331 in a direction parallel to the pixel layer), W S1H1 and W S1H2 are the shortest distances between the first isolation column 331 and the first light-transmitting hole 311 and the second light-transmitting hole 312 in a direction parallel to the pixel layer, and H is the height distance from the light-shielding layer to the pixel layer.

[0104] when Figure 3When the dimensions satisfy the above formulas (1) and (2), the first isolation column 331 can have a sufficient height to block the light emitted by the first pixel 321 from being emitted to the second light-transmitting hole 312 or the light emitted by the second pixel 322 from being emitted to the first light-transmitting hole 311, which can reduce the viewing angle of each pixel and reduce the mutual interference between the light emitted by the pixels. In this way, the display effect of the display panel at different angles can be improved, and the images of different pixels can have a certain anti-peeping screen effect respectively, and this size relationship can facilitate the design of the display panel.

[0105] Optionally, in some possible implementations, in a direction parallel to the pixel layer, the size of the first pixel may be greater than or equal to the size of the first light-transmitting hole, and the size of the second pixel may also be greater than or equal to the size of the second light-transmitting hole.

[0106] For example, Figure 4 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Figure 4 As shown, the display panel includes a first pixel 421 and a second pixel 422 on the pixel layer, a first light-transmitting hole 411 and a second light-transmitting hole 412 on the light-shielding layer, and a spacer 431 located between the first pixel 421 and the second pixel 422. In the direction parallel to the pixel layer, the width W1 of the first pixel 421 is greater than or equal to the width W of the first light-transmitting hole 411. H1 On the other hand, in the direction parallel to the pixel layer, the width W2 of the second pixel 422 may also be greater than or equal to the width W of the second light-transmitting hole 412. H2 .

[0107] Figure 4 In the figure, when the light emitted by the first pixel 421 is emitted toward the top of the panel along the arrow direction shown in the figure, the light of the pixel can fill the entire first light-transmitting hole 411, and the brightness that can be seen at this time is the highest. When the light emitted by the left part of the first pixel 421 fills the first light-transmitting hole 411, the range limit of the light passing through the first light-transmitting hole 411 is shown by the solid arrow; when the light emitted by the right part of the first pixel 421 fills the first light-transmitting hole 411, the range limit of the light passing through the first light-transmitting hole 411 is shown by the dotted arrow. An angle θ is formed between the direction pointed by the solid arrow and the dotted arrow. Each angle within the range of angle θ corresponds to some parts on the first pixel 421, and the light emitted by these parts can fill the first light-transmitting hole 411. That is, within the angle θ, the light emitted by the first pixel 421 can always fill the entire first light-transmitting hole 411. Angle θ is the preferred target viewing angle of the first pixel 421. The second pixel 422 and the second light-transmitting hole 412 are similar to the first pixel 421 and the first light-transmitting hole 411 .

[0108] In the above implementation, the pixel size is designed to be larger than the corresponding light-transmitting hole size, which is conducive to forming some better target viewing angles. Within these target viewing angles, the pixel display width is large and the display effect is good. When the pixel size is further increased compared to the light-transmitting hole size, the range of the better target viewing angle will also increase, so that the display panel has a better display effect at a larger angle.

[0109] Optionally, in some possible implementations, in a direction parallel to the pixel layer, the first pixel and the second pixel have the same size.

[0110] In this way, the display screen of the panel at different viewing angles is symmetrical, and the display effect is relatively balanced. In addition, the design of pixels of the same size is also convenient for hardware design and implementation, which is conducive to reducing the manufacturing cost of the display panel.

[0111] Optionally, in some possible implementations, in a direction parallel to the pixel layer, sizes of the first pixel and the second pixel are not equal.

[0112] Exemplarily, the size of the first pixel may be greater than the size of the second pixel. Figure 5 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Figure 5 As shown, the panel includes a first pixel 521 and a second pixel 522 on the pixel layer, a first light-transmitting hole 511 and a second light-transmitting hole 512 on the light-shielding layer, and a spacer 531 between the first pixel 521 and the second pixel 522. In the direction parallel to the pixel layer, the width W1 of the first pixel 521 is greater than the width W2 of the second pixel 522.

[0113] In this way, the light emitted by the first pixel through the first light-transmitting hole is greater than the light emitted by the second pixel through the second light-transmitting hole, the display effect of the first pixel is better than that of the second pixel, and the display effects of the two pixels can be adjusted with emphasis.

[0114] Optionally, in this embodiment, the first light-transmitting hole 511 corresponding to the first pixel 521 may be larger than the second light-transmitting hole 512 corresponding to the second pixel 522. Optionally, the width of the first light-transmitting hole 511 may be larger than the width of the first pixel 521, and the width of the second light-transmitting hole 512 may be larger than the width of the second pixel 522.

[0115] Optionally, in some possible implementations, the first pixel and the second pixel are located below the first light-shielding area, and the first pixel and the second pixel are located in the orthographic projection of the first light-shielding area on the pixel layer.

[0116] For example, Figure 6 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Figure 6As shown, the panel includes a first pixel 621 and a second pixel 622 on a pixel layer 620, a first light-transmitting hole 611 and a second light-transmitting hole 612 on a light-shielding layer 610, and a first light-shielding region 613 located between the two light-transmitting holes, and a spacer column 631 located between the first pixel 621 and the second pixel 622. The first pixel 621 and the second pixel 622 are both located below the first light-shielding region 613.

[0117] In this way, the light emitted by the first pixel and the second pixel is difficult to be emitted at an angle perpendicular to the display panel, which can prevent the light of the first pixel and the second pixel from interfering with each other at an angle perpendicular to the display panel, thereby improving the display effect.

[0118] Optionally, in some possible implementations, the isolation column layer of the display panel may further include a second isolation column, which is located on the left side of the first pixel. The light-shielding layer may further include a third light-transmitting hole, which is located on the left side of the first light-transmitting hole. The first pixel is located below the first light-transmitting hole, and the second isolation column is used to block the light of the first pixel from being directed toward the third light-transmitting hole.

[0119] For example, Figure 7 is a schematic structural diagram of another display panel provided in an embodiment of the present application. Figure 7 As shown, in the display panel, the light shielding layer includes a third light transmission hole 713, a first light transmission hole 711, and a second light transmission hole 712, which are arranged in sequence from left to right; the isolation column layer includes a second isolation column 732 and a first isolation column 731; and the pixel layer includes a first pixel 721 and a second pixel 722. Among them, the second isolation column 732, the first pixel 721, the first isolation column 731, and the second pixel 722 are arranged in sequence from left to right, the first pixel 721 is located below the first light transmission hole 711, and the second isolation column 732 blocks the light emitted from the first pixel 721 from being emitted to the third light transmission hole 713.

[0120] In this way, by adding a second isolation column, the angle at which the light emitted by the first pixel can be emitted is adjusted, so that the light of the first pixel can be emitted perpendicularly to the display panel outward through the first light-transmitting hole, that is, the display angle of the first pixel can be a front viewing angle perpendicular to the display panel, which can more conveniently adjust the display angle of the first pixel and improve the display effect of the display panel.

[0121] Specifically, in the above implementation, the relevant dimensions of the second isolation column and the third light-transmitting hole satisfy a certain relationship.

[0122] Figure 8 yes Figure 7 Schematic diagram of the size position relationship in the display panel of the implementation shown in FIG. Figure 8As shown, the first pixel 821 is located below the first light-transmitting hole 811 , and the second isolation column 831 blocks the light of the first pixel 821 from being emitted to the third light-transmitting hole 812 . Figure 8 The dimensions in satisfy the following relationship:

[0123] h2×(W1+W S2 +W S2H3 )≥H×W1(3)

[0124] Wherein, h2 is the height of the second isolation column 831, W1 is the width of the first pixel 821, and W S2 is the width of the second isolation column 831, W S2H3 is the shortest distance between the second isolation column 831 and the third light-transmitting hole 812 in a direction parallel to the pixel layer, and H is the distance from the light-shielding layer to the pixel layer.

[0125] when Figure 8 When the dimensions satisfy the above formula, the second isolation column can have a sufficient height to block the light emitted by the first pixel from being emitted to the third light-transmitting hole, so that the viewing angle of the first pixel can be reduced. The first pixel is located below the first light-transmitting hole. In this way, the viewing angle of the first pixel can be adjusted to include directly above, while reducing the light emitted by the first pixel from being emitted from the third light-transmitting hole, which has a certain anti-peeping screen effect.

[0126] In the above embodiment, in the pixel layer of the display panel, a group of pixels includes two pixels (i.e., the first pixel and the second pixel above), thereby realizing a display panel with two viewing angles. In other embodiments, for the pixel layer of the display panel, a group of pixels may also include a larger number of pixels to realize a display panel with more viewing angles.

[0127] Optionally, in some possible implementations, in the pixel layer of the display panel, a group of pixels may include: a first pixel, a second pixel and a third pixel, wherein the first pixel is located between the second pixel and the third pixel. The light shielding layer is provided with a first light-transmitting hole, a second light-transmitting hole and a third light-transmitting hole corresponding to the three pixels, respectively, that is, the first light-transmitting hole is located between the second light-transmitting hole and the third light-transmitting hole. The isolation column layer includes: a first isolation column and a second isolation column, wherein the first isolation column is located between the first pixel and the second pixel, and the second isolation column is located between the first pixel and the third pixel. The first isolation column is used to block light interference between the first pixel and the second pixel, and the second isolation column is used to block light interference between the first pixel and the third pixel.

[0128] For example, Fig. 9 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Fig. 9As shown, in the display panel, the light shielding layer 910 includes a third light-transmitting hole 913, a second light-shielding area 915, a first light-transmitting hole 911, a first light-shielding area 914, and a second light-transmitting hole 912, which are arranged from left to right; the isolation column layer includes a second isolation column 932 and a first isolation column 931; and the pixel layer includes a third pixel 923, a first pixel 921, and a second pixel 922. Among them, the third pixel 923, the second isolation column 932, the first pixel 921, the first isolation column 931, and the second pixel 922 are arranged from left to right. The second isolation column 932 blocks the light emitted from the first pixel 921 from the third light-transmitting hole 913, and blocks the light emitted from the third pixel 923 from the first light-transmitting hole 911. The first isolation column 931 blocks the light emitted from the first pixel 921 from the second light-transmitting hole 912, and blocks the light emitted from the second pixel 922 from the first light-transmitting hole 911. In the θ1 angle range (first viewing angle range), the light emitted by the first pixel 921 through the first light-transmitting hole 911 can be seen. Similarly, in the θ2 angle range (second viewing angle range), the light emitted by the second pixel 922 through the second light-transmitting hole 912 can be seen; in the θ3 angle range (third viewing angle range), the light emitted by the third pixel 923 through the third light-transmitting hole 913 can be seen.

[0129] In this way, the display panel can emit light of different pixels in three directions respectively, so as to realize three-viewing angle display, and the three viewing angles do not interfere with each other. Except for the three viewing angles, there is no display image at other viewing angles, which has a better anti-peeping effect.

[0130] Optionally, in some possible implementations, the first pixel is directly below the first light-transmitting hole.

[0131] In this way, the light emitted by the first pixel can be emitted in a direction perpendicular to the display panel, that is, the visible angle of the first pixel can be adjusted to a normal viewing angle.

[0132] Optionally, in some possible implementations, in a direction parallel to the pixel layer, a size of the third pixel is greater than or equal to a size of the third light-transmitting hole.

[0133] In this way, at some preferred target viewing angles, the light emitted by the third pixel can fill the third light-transmitting hole, and the display width of the third pixel is large and the display effect is good. When the size of the third pixel is further increased compared to the size of the light-transmitting hole, the range of the preferred target viewing angle will also increase accordingly, so that the display panel has a larger preferred target viewing angle with better display effect within the viewing angle of the third pixel.

[0134] Optionally, in some possible implementations, in a direction parallel to the pixel layer, the second pixel and the third pixel are equal in size.

[0135] In this way, the display screen of the panel in the left and right directions is symmetrical.

[0136] Optionally, in some possible implementations, in a direction parallel to the pixel layer, sizes of the second pixel and the third pixel are not equal.

[0137] Exemplarily, the size of the second pixel may be larger than that of the third pixel.

[0138] In this way, the light emitted by the second pixel through the second light-transmitting hole is greater than the light emitted by the third pixel through the thirteenth light-transmitting hole, the display effect of the second pixel is better than that of the third pixel, and the display effects of the left and right pixels can be adjusted.

[0139] Optionally, in some possible implementations, in a direction parallel to the pixel layer, the size of the first pixel is greater than or equal to the size of the second pixel, and / or the size of the first pixel is greater than or equal to the size of the third pixel.

[0140] As an example, the size of the first pixel is larger than the size of the second pixel and the third pixel. Fig.10 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Fig.10 As shown, in the display panel, the light shielding layer 1010 includes a third light-transmitting hole 1013, a second light-shielding area 1015, a first light-transmitting hole 1011, a first light-shielding area 1014, and a second light-transmitting hole 1012, which are arranged from left to right; the isolation column layer includes a second isolation column 1032 and a first isolation column 1031; and the pixel layer includes a third pixel 1023, a first pixel 1021, and a second pixel 1022. Among them, the third pixel 1023, the second isolation column 1032, the first pixel 1021, the first isolation column 1031, and the second pixel 1022 are arranged from left to right. The second isolation column 1032 blocks the light emitted from the first pixel 1021 from being emitted to the third light-transmitting hole 1013, and blocks the light emitted from the third pixel 1023 from being emitted to the first light-transmitting hole 1011. The first isolation column 1031 blocks the light emitted from the first pixel 1021 from being emitted to the second light-transmitting hole 1012, and blocks the light emitted from the second pixel 1022 from being emitted to the first light-transmitting hole 1011. The width W1 of the first pixel 1021 is greater than the size W2 of the second pixel 1022 and the size W3 of the third pixel 1023. Within the angle range of θ1, the light emitted from the first pixel 1021 through the first light-transmitting hole 1011 can be seen.

[0141] In this way, the viewing angle of the first pixel (ie, the angle range of θ1) can be increased, thereby enhancing the display effect of the first pixel.

[0142] Optionally, in some possible implementations, the third pixel is located below the second light-shielding area.

[0143] In this way, the light emitted by the third pixel is difficult to be emitted outward at an angle perpendicular to the display panel, which can reduce the interference between the light emitted by the third pixel and the light emitted by the first pixel, thereby improving the display effect.

[0144] Optionally, in some possible implementations, relevant sizes of the second isolation column, the first light-transmitting hole, and the third light-transmitting hole satisfy a certain relationship.

[0145] Fig.11 FIG. 1 is a schematic diagram of the size and position relationship of the display panel in the above implementation. Fig.11 As shown, in the display panel, the light shielding layer includes a third light-transmitting hole 1113, a second light-shielding area 1115, a first light-transmitting hole 1111, a first light-shielding area 1114, and a second light-transmitting hole 1112, which are arranged from left to right; the isolation column layer includes a second isolation column 1132 and a first isolation column 1131; and the pixel layer includes a third pixel 1123, a first pixel 1121, and a second pixel 1122. Among them, the third pixel 1123, the second isolation column 1132, the first pixel 1121, the first isolation column 1131, and the second pixel 1122 are arranged from left to right. The light emitted by the first pixel 1121 can pass through the first light-transmitting hole 1111, the light emitted by the second pixel 1122 can pass through the second light-transmitting hole 1112, and the light emitted by the third pixel 1123 can pass through the third light-transmitting hole 1113. The second isolation column 1132 blocks the light emitted from the first pixel 1121 from being emitted to the third light-transmitting hole 1113, and blocks the light emitted from the third pixel 1123 from being emitted to the first light-transmitting hole 1111. In order to achieve the above effect, Fig.11 The dimensions satisfy the following relationship:

[0146] h2×(W1+W S2 +W S2H3 )≥H×W1(3)

[0147] h2×(W3+W S2 +W S2H1 )≥H×W3(4)

[0148] Wherein, h2 is the height of the second isolation column 1132, W1 is the width of the first pixel 1121, W3 is the width of the third pixel 1123, and W S2 is the width of the second isolation column 1132, W S2H1 and W S2H3 are the shortest distances between the second isolation column 1132 and the first light-transmitting hole 1111 and the third light-transmitting hole 1113 in a direction parallel to the pixel layer, and H is the distance from the light-shielding layer to the pixel layer.

[0149] when Fig.11When the dimensions satisfy the above formula, the second isolation column 1132 can have a sufficient height to block the light emitted by the first pixel 1121 from being emitted to the third light-transmitting hole 1113 or the light emitted by the third pixel 1123 from being emitted to the first light-transmitting hole 1111, which can reduce the viewing angle of each pixel and reduce the mutual interference between the light emitted by the pixels. In this way, the display effect of the display panel at different angles can be improved, and the pictures of different pixels can have a certain anti-peeping screen effect respectively, and this size relationship can facilitate the design of the display panel.

[0150] It should be noted that the above formulas (1), (2), (3) and (4) can be satisfied simultaneously.

[0151] Optionally, in some possible implementations, the display panel further includes more pixels, spacer columns, light-transmitting holes, and shielding areas, and the number of newly added pixels, spacer columns, light-transmitting holes, and shielding areas is not limited. For example, the display panel may further include a third spacer column, a fourth pixel, a third shielding area, and a fourth light-transmitting hole corresponding to the fourth pixel, and the newly added spacer column, pixel, light-transmitting hole, and shielding area also satisfy a size relationship similar to the above formula (1), (2) or formula (3), (4), so that the newly added spacer column can have a sufficient height to block the interference between the light emitted by the pixels.

[0152] Optionally, in some possible implementations, the display panel includes multiple groups of pixels, each group of pixels includes n pixels, and the relative position relationship of the n pixels in each group is the same. n is an integer greater than or equal to 2. In the multiple groups of pixels, the i-th pixel in each group of pixels is used to display the i-th picture. i is a positive integer less than or equal to n.

[0153] For example, each pixel group may have two pixels, with the left side of each pixel group being the first pixel and the right side being the second pixel. The plurality of first pixels may be used to display the first picture, and the plurality of second pixels may be used to display the second picture.

[0154] For example, there may be 3 pixels in each group of pixels. As an example, Fig.12 is a schematic structural diagram of a display panel provided in an embodiment of the present application. Fig.12As shown, in the display panel, there are multiple groups of pixels: a first pixel group 1210, a second pixel group 1220, and a third pixel group 1230. Among them, in each pixel group, the middle pixel is the first pixel, the right pixel is the second pixel, and the left pixel is the third pixel. In the multiple groups of pixels of the display panel, the light of each first pixel is emitted at the same angle, so that the light emitted by multiple first pixels can be seen at the same angle. In this way, each first pixel can display the first picture together. Similar to the first pixel, multiple second pixels can be used to display the second picture, and multiple third pixels can be used to display the third picture.

[0155] Through this implementation, the pixels used to display the same picture are set at the same position in each group of pixels, which is beneficial to hardware design and also convenient for subsequent testing and positioning of display performance. Optionally, in the above implementation, the display panel includes pixels of multiple colors, and each group of pixels has the same color or at least some of the pixels have different colors.

[0156] As an example, the display panel may include pixels of three colors: red, green, and blue, and multiple groups of pixels may include red pixels, green pixels, and blue pixels at the same time. The colors of multiple pixels in each group of pixels may be the same, partially the same, or completely different.

[0157] As an example, the multiple groups of pixels of the display panel include a first type of pixel group, a second type of pixel group and a third type of pixel group. The above three types of pixel groups respectively include 1 red, 1 green and 1 blue, that is, each type of pixel group includes 3 pixels. Fig.13 is a schematic diagram of the structure of the above three types of pixel groups. Fig.13 As shown in (a), in the first type of pixel group 1310, pixel 1311 is a red pixel, pixel 1312 is a green pixel, and pixel 1313 is a blue pixel. Fig.13 As shown in (b), in the second type of pixel group 1320, pixel 1321 is a green pixel, pixel 1322 is a blue pixel, and pixel 1323 is a red pixel. Fig.13 As shown in (c), in the third type pixel group 1330, pixel 1331 is a blue pixel, pixel 1332 is a red pixel, and pixel 1333 is a green pixel. In this way, one or more first type pixels, one or more second type pixels, and one or more third type pixels, the above combination can enable the display panel to display red, green, and blue in multiple directions.

[0158] In this way, each picture of the display panel can have rich colors.

[0159] Optionally, in some possible implementations, the height of the isolation column is lower than the distance between the light shielding layer and the pixel layer, that is, there is a gap between the top of the isolation column and the pixel layer.

[0160] In this way, the isolation layer and the light shielding layer do not abut against each other, and when the display panel is manufactured and packaged, the packaging layer has a better sealing effect on the pixel layer.

[0161] In the above embodiments, a group of pixels in the pixel layer is distributed in the same direction parallel to the pixel layer. For example, when a group of pixels includes three pixels, the three pixels are arranged in a row. In some alternative embodiments, the three pixels can be arranged in any manner in the same plane, and the embodiments of the present application do not limit this. In addition, it can be understood that when a group of pixels in the pixel layer also includes more than three pixels, the more than three pixels can also be arranged in any manner in the same plane, and the embodiments of the present application do not specifically limit the number and arrangement of a group of pixels.

It is understandable that the following method embodiment may correspond to the above device embodiment, and the description of relevant technical features may refer to the specific introduction of the above embodiment, and the repetitive parts will not be described in detail below.

[0163] Fig.14 A schematic flowchart of a method 1400 for manufacturing a display panel provided in an embodiment of the present application is shown.

[0170] The light shielding layer is located above the isolation column layer and includes a first light-transmitting hole and a second light-transmitting hole. A first light-shielding area between the first light-transmitting hole and the second light-transmitting hole is located above the first isolation column.

[0171] Among them, the first light-transmitting hole is used to pass the light signal of the first angle emitted by the first pixel, the second light-transmitting hole is used to pass the light signal of the second angle emitted by the second pixel, and the first isolation column is used to block the light signal emitted by the first pixel toward the second light-transmitting hole, and block the light signal emitted by the second pixel toward the first light-transmitting hole.

[0172] It should be understood that the logical relationship between the above steps is not limited by order. For example, in some possible implementations, the order of the above steps can be adjusted, for example, the preparation of the pixel layer can be before or after the preparation of the isolation column layer. For another example, in some possible implementations, the above steps can be performed simultaneously, for example, the preparation of the pixel layer and the preparation of the isolation column layer can be performed simultaneously. For another example, in some possible implementations, the above steps can be performed crosswise, for example, before preparing the isolation column layer, some processes in the preparation of the pixel layer are started, and after the preparation of the isolation column layer is completed, other processes in the preparation of the pixel layer are performed. Where possible, various implementations of the above steps can be repeated or combined.

[0173] Optionally, in some possible implementations, preparing the pixel layer includes preparing a pixel circuit and evaporating a pixel filter layer.

[0174] Fig.15 A schematic flowchart of another method 1500 for manufacturing a display panel provided in an embodiment of the present application is shown. The manufacturing method 1500 includes the following steps.

[0175] S1510, prepare a pixel circuit backplane.

[0176] The pixel circuit backplane includes a pixel circuit. For example, when the pixel layer includes a first pixel and a second pixel, the pixel circuit backplane may include a first pixel circuit of the first pixel and a second pixel circuit of the second pixel. It is understandable that when the pixel layer includes multiple groups of pixels, the pixel circuit backplane corresponds to a pixel circuit of each pixel in the multiple groups of pixels.

[0177] S1520, preparing a pixel definition layer.

[0178] The pixel definition is used to define different groups of pixels in the pixel layer. For example, the pixel definition layer includes a first pixel definition area, and the first pixel definition area is located outside the first pixel circuit and the second pixel circuit, thereby defining a group of pixels formed by the first pixel and the second pixel.

[0179] S1530, preparing an isolation column layer.

[0180] The isolation column layer may include a plurality of isolation columns, and the isolation columns are located between two adjacent pixel circuits in each group of pixel circuits. For example, the isolation column layer includes a first isolation column, and the first isolation column is located between the first pixel circuit and the second pixel circuit.

[0181] Optionally, in some possible implementations, the pixel definition layer and the isolation column layer are made of black photoresist material and are manufactured in one step through a halftone process.

[0182] By simultaneously manufacturing the pixel definition layer and the isolation column layer using a one-step process, the number of process steps can be reduced and the manufacturing efficiency can be improved.

[0183] Optionally, in some possible implementations, the pixel definition layer and the isolation column layer can also be made separately through two-step processes. The pixel definition layer can be made of transparent photoresist, black photoresist or other materials, or one or more of these materials; the isolation column layer can be made of black photoresist, metal, or other materials, or a combination of transparent photoresist and metal plating, or one or more of these materials or combinations.

[0184] In this way, the pixel definition layer and the isolation column layer can be made of different materials or a combination of materials, and different materials can be selected to prepare light shielding layers with different costs or performances.

[0185] S1540, preparing a filter layer.

[0186] The filter layer may include a plurality of filter regions corresponding to the plurality of pixel circuits in the pixel circuit backplane. As an example, the filter layer includes a first filter region located above the first pixel and a second filter region located above the second pixel.

[0187] Optionally, in some possible implementations, the filter layer includes three colors: red, blue and green.

[0188] Optionally, in some possible implementations, the filter layer is manufactured by an evaporation process.

[0189] Optionally, in some possible implementations, the filter layers of multiple colors are prepared by evaporation in multiple steps, with each step preparing one color. For example, the evaporation step can be divided into three steps, and red, green, and blue are sequentially evaporated in the three evaporation steps.

[0190] Optionally, in some possible implementations, the filter layer may be evaporated by a fine metal mask (Fine Metal Mask, FMM) process.

[0191] Optionally, in some possible implementations, the filter layer is manufactured by a fine metal mask (FMM) process, and the isolation column layer is used as a supporting structure in the fine metal mask process to define the distance between the fine metal mask and the pixel layer.

[0192] S1550, preparing an encapsulation layer.

[0193] The encapsulation layer is prepared above the filter layer and is used for encapsulating the filter layer, the isolation column layer and the pixel circuit backplane.

[0194] Optionally, in some possible implementations, the encapsulation layer includes silicon nitride (SiN) and an inkjet printing (IJP) layer.

[0195] Optionally, in some possible implementations, the encapsulation layer includes three layers of SiN / IJP / SiN from bottom to top.

[0196] S1560, preparing a light shielding layer.

[0197] The light shielding layer is prepared above the encapsulation layer and has a light shielding area and light-transmitting holes corresponding to the pixels.

[0198] It should be understood that the order of the above steps is not limited. For example, S1520 and S1530 can be swapped.

[0199] Fig.15 A schematic flow chart of one of the manufacturing methods in the above implementation manner is shown. Fig.16 (a) to (f) correspond to Fig.15 The structure diagram after steps S1510 to S1560 in the manufacturing method are completed. Fig.16 In the figure, 1611 is the pixel circuit. Fig.16 In (a), the first and third pixel circuits from left to right are first pixel circuits, and the second and fourth pixel circuits are second pixel circuits; 1621 is a pixel definition layer, 1622 and 1623 are pixel circuits of two groups of pixels respectively, each group of pixels consists of a first pixel on the left and a second pixel on the right, and the pixel definition layer is located at the periphery of each group of pixels; 1631 is an isolation column; 1641 is a pixel filter layer; 1651 is an encapsulation layer; and 1661 is a shading layer.

[0200] It should also be understood that Fig.15 The manufacturing method shown does not constitute a limitation to the above implementation manner.

[0201] In this way, through the manufacturing method provided by the implementation mode of the embodiment of the present application, a display panel including an isolation column layer can be manufactured. This display panel can display multiple pictures on a display panel, and can control the viewing angle of the display panel to reduce screen peeking.

[0202] Optionally, in some possible implementations, the manufacturing method further includes:

[0203] S1710, preparing a flat protective layer above the encapsulation layer and the light shielding layer.

[0204] Fig.17 is a schematic structural diagram of the display panel after S1710 is completed. Fig.17 As shown, there is a flat protective layer 1701 above the light shielding layer.

[0205] In this way, the light shielding layer can be protected and the service life of the display panel can be increased.
