[0094] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the protection scope of this disclosure.
[0095] It should be noted that, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be enlarged in the accompanying drawings. Therefore, the dimensions and relative dimensions of the individual components are not necessarily limited to those shown in the drawings. In the specification and accompanying drawings, the same or similar reference numerals indicate the same or similar parts.
[0096] When an element is described as being "on" another element, "connected to" another element, or "attached to" another element, the element may be directly on, directly connected to, or directly attached to the other element, or there may be intermediate elements. However, when an element is described as being "directly on" another element, "directly connected to" another element, or "directly attached to" another element, there are no intermediate elements. Other terms and / or expressions used to describe relationships between elements should be interpreted in a similar manner, such as "between" versus "directly between," "adjacent" versus "directly adjacent," or "on" versus "directly on," etc. Furthermore, the term "connection" can refer to a physical connection, an electrical connection, a communication connection, and / or a fluid connection. Moreover, the X-axis, Y-axis, and Z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z such as XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the listed related items.
[0097] It should be noted that although the terms "first," "second," etc., may be used herein to describe various components, members, elements, regions, layers, and / or parts, these components, members, elements, regions, layers, and / or parts should not be limited by these terms. Rather, these terms are used to distinguish one component, member, element, region, layer, and / or part from another. Thus, for example, the first component, first member, first element, first region, first layer, and / or first part discussed below may be referred to as a second component, second member, second element, second region, second layer, and / or second part without departing from the teachings of this disclosure.
[0098] For ease of description, spatial relation terms, such as “above,” “below,” “left,” “right,” etc., may be used herein to describe the relationship between one element or feature and another element or feature as shown in the figure. It should be understood that spatial relation terms are intended to cover other orientations of the device in use or operation besides those described in the figure. For example, if the device in the figure were inverted, an element described as “below” or “under” other elements or features would be oriented “above” or “on top” other elements or features.
[0099] In this document, the term "repeating unit" refers to a combination of multiple subpixels, such as a combination of multiple subpixels used to display a single pixel. Multiple "repeating units" are arranged in an array and repeated on a substrate. For example, a repeating unit may include two, three, four, or more subpixels. Furthermore, for ease of description, a repeating unit located in a first display area is referred to as a first repeating unit, and a repeating unit located in a second display area is referred to as a second repeating unit.
[0100] In this paper, the term "pixel density" refers to the number of repeating units or subpixels per unit area. Similarly, the term "distribution density" refers to the number of components (e.g., repeating units, subpixels, spacers, etc.) per unit area.
[0101] This disclosure provides a display panel including a first display area and a second display area. The display panel includes: a substrate; a plurality of first repeating units arranged in an array on the substrate and located in the first display area, each first repeating unit including at least a first sub-pixel; a plurality of second repeating units arranged in an array on the substrate and located in the second display area, each second repeating unit including at least a second sub-pixel, the first sub-pixel and the second sub-pixel emitting light of the same color; and a pixel defining layer disposed on the substrate and located in both the first and second display areas, the pixel defining layer including a first opening in the first display area and a second opening in the second display area, wherein the pixel density of the first display area is greater than the pixel density of the second display area; and the first sub-pixel includes the first opening, the second sub-pixel includes the second opening, and the area of the orthographic projection of the second opening onto the substrate is greater than the area of the orthographic projection of the first opening onto the substrate. This improves the display uniformity of the first and second display areas and also enhances the uniformity of the lifetime of the luminescent materials in the first and second display areas.
[0102] Figure 1 This is a plan view of a display panel according to some exemplary embodiments of the present disclosure. Figure 2 The display panel is based on some exemplary embodiments of this disclosure. Figure 1 A schematic diagram of the cross section intercepted by line AA' in the diagram. Figure 3 yes Figure 1 The diagram shows a partial enlarged view of the display panel. Each dashed box represents a repeating unit, and each rectangle represents a subpixel.
[0103] Reference Figures 1 to 3 The display panel includes a first display area AA1 and a second display area AA2 at least partially surrounded by the first display area AA1. The first display area AA1 includes a plurality of first repeating units P1 arranged in an array, and the second display area AA2 includes a plurality of second repeating units P2 arranged in an array. The first repeating unit P1 may further include a plurality of sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels; similarly, the second repeating unit P2 may further include a plurality of sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels.
[0104] It should be noted that the embodiments of this disclosure are described using red, green, and blue as examples. However, the embodiments of this disclosure are not limited to this. That is, each repeating unit may include a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel, wherein the first color, the second color, and the third color are different from each other. In this document, for ease of description, the sub-pixels included in the first repeating unit P1 are referred to as the first sub-pixel, the third sub-pixel, and the fifth sub-pixel, respectively, and the sub-pixels included in the second repeating unit P2 are referred to as the second sub-pixel, the fourth sub-pixel, and the sixth sub-pixel, respectively. For example, the first sub-pixel and the second sub-pixel can be red sub-pixels, the third sub-pixel and the fourth sub-pixel can be blue sub-pixels, and the fifth sub-pixel and the sixth sub-pixel can be green sub-pixels. However, the embodiments of this disclosure are not limited to this. In other embodiments, each repeating unit may include four sub-pixels. For example, the first repeating unit P1 may include the first sub-pixel, the third sub-pixel, the fifth sub-pixel, and the seventh sub-pixel, and the second repeating unit P2 may include the second sub-pixel, the fourth sub-pixel, the sixth sub-pixel, and the eighth sub-pixel. For example, two of the four sub-pixels in each repeating unit can form one pixel unit, and the other two of the four sub-pixels in each repeating unit can form another pixel unit. That is, each repeating unit can include two pixel units.
[0105] It should be noted that in the exemplary embodiment illustrated, the first display area AA1 surrounds the second display area AA2; however, the embodiments of this disclosure are not limited thereto. For example, in other embodiments, the second display area AA2 may be located at the upper edge of the display panel. For instance, the second display area AA2 may be surrounded on three sides by the first display area AA1, and its upper side may be flush with the upper side of the display panel. As another example, the second display area AA2 may be located at the upper edge of the display panel and arranged along the entire width of the display panel.
[0106] like Figure 3 As shown, the first display area AA1 has a first pixel density, and the second display area AA2 has a second pixel density that is less than the first pixel density.
[0107] In the second display area AA2, the blank areas between the multiple second repeating units P2 allow more light to pass through, thereby increasing the light transmittance of that area. Therefore, the second display area AA2 has a greater light transmittance than the first display area AA1.
[0108] It should be noted that, in this paper, the blank area between multiple second repeating units P2 can be referred to as the light-transmitting area TRA.
[0109] like Figure 2 As shown, the display panel may include a substrate 1. An image sensor 2 may be disposed on the back side of the substrate 1 located in the second display area AA2 (on the substrate 1). Figure 2 (As shown in the lower part), the second display area AA2 can meet the imaging requirements of the image sensor 2 for light transmittance.
[0110] exist Figures 1 to 3 The display panel shown can utilize OLED display technology. Due to its advantages such as wide viewing angle, high contrast, fast response, low power consumption, foldability, and flexibility, OLED display panels are increasingly widely used in display products. With the development and widespread application of OLED display technology, the demand for displays with high screen-to-body ratios is becoming increasingly strong. Figures 1 to 3 The display panel shown employs an under-display camera solution. This eliminates the notch area, avoids cutting holes in the display, and increases the screen-to-body ratio, resulting in a better visual experience.
[0111] Furthermore, the display panel may also include a driving circuit layer, a light-emitting device layer, and an encapsulation layer disposed on the substrate 1. For example, Figure 2 The diagram schematically illustrates a driving circuit layer 3, a light-emitting device layer 4, and an encapsulation layer 5. The driving circuit layer 3 includes a driving circuit structure, and the light-emitting device layer 4 includes light-emitting devices such as those used in OLEDs. The driving circuit structure controls the light-emitting devices of each sub-pixel to emit light, thereby achieving a display function. This driving circuit structure includes thin-film transistors, storage capacitors, and various signal lines. These signal lines include gate lines, data lines, ELVDD power lines, and ELVSS power lines, etc., to provide control signals, data signals, power supply voltages, and other signals to the pixel driving circuit in each sub-pixel.
[0112] Figure 4 yes Figure 3 A magnified schematic diagram of part I in the diagram. Figure 5 According to some exemplary embodiments of this disclosure, along Figure 4 A schematic diagram of the cross-section intercepted by line BB' in the diagram. (Refer to reference...) Figure 4 and Figure 5The display panel may include: an anode 41 disposed on a substrate 1; a pixel defining layer 6 disposed on the side of the anode 41 away from the substrate 1; a light-emitting layer 42 disposed on the side of the pixel defining layer 6 away from the substrate 1; and a cathode 43 disposed on the side of the light-emitting layer 42 away from the substrate 1.
[0113] It should be understood that the light-emitting layer 42 may be, for example, an organic light-emitting layer, and correspondingly, the anode 41, the organic light-emitting layer 42, and the cathode 43 constitute the light-emitting device of the aforementioned OLED, for example.
[0114] like Figure 4 and Figure 5 As shown, the pixel defining layer 6 may include a plurality of openings 62. The plurality of openings 62 are located in a plurality of sub-pixels, for example, one opening 62 is provided in each sub-pixel. Each opening 62 exposes a portion of the anode 41. A portion of the light-emitting layer 42 fills the opening 62 to contact the exposed portion of the anode 41.
[0115] The actual light-emitting area of each sub-pixel is determined by the area of the part of the light-emitting layer 42 that contacts the anode 41, that is, by the area of each opening 62 of the pixel defining layer 6, or more specifically, by the area of the orthogonal projection of each opening 62 onto the substrate 1.
[0116] Furthermore, considering the color mixing effect between two adjacent sub-pixels, the opening 62 between two adjacent sub-pixels (e.g., sub-pixels SP1 and SP2) needs to be spaced at a specified distance, such as... Figure 4 The distance d in the figure is shown.
[0117] Thus, in each sub-pixel, the area of the opening 62 (i.e. the actual light-emitting area) is smaller than the total pixel area of the sub-pixel.
[0118] In this document, the aperture ratio of a sub-pixel can be expressed as the ratio of its actual light-emitting area to the total pixel area. As mentioned above, the actual light-emitting area of a sub-pixel is determined by the area of the orthographic projection of each opening 62 onto the substrate 1. Furthermore, the total pixel area of the sub-pixel can be determined in the following manner. For example, those skilled in the art should understand that each sub-pixel has its own pixel circuit, which is periodically arranged on the substrate. Therefore, the total pixel area of a sub-pixel can be determined by calculating the area of its pixel circuit's orthographic projection onto the substrate. (Referring to reference...) Figure 4 The aperture ratio of a sub-pixel can be expressed by the following formula:
[0119]
[0120] Where AR represents the aperture ratio of the sub-pixel, SR S represents the actual light-emitting area of the sub-pixel. pixel This represents the total pixel area of a sub-pixel.
[0121] Figure 6A This is a plan view of a first repeating unit located in a first display area of a display panel according to some exemplary embodiments of the present disclosure. Figure 6B This is a plan view of a second sub-repeating unit located in a second display area of a display panel according to some exemplary embodiments of the present disclosure.
[0122] For example, Figure 6A A first repeating unit P1 shown may include a first sub-pixel SP1 (e.g., a red sub-pixel), a third sub-pixel SP3 (e.g., a blue sub-pixel), and a fifth sub-pixel SP5 (e.g., a green sub-pixel); Figure 6B A second repeating unit P2 shown may include a second sub-pixel SP2 (e.g., a red sub-pixel), a fourth sub-pixel SP4 (e.g., a blue sub-pixel), and a sixth sub-pixel SP6 (e.g., a green sub-pixel). The colors of the light emitted by the first sub-pixel SP1, the third sub-pixel SP3, and the fifth sub-pixel SP5 are the same as the colors of the light emitted by the second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth sub-pixel SP6, respectively.
[0123] As described above, the sub-pixels located in the first display area AA1 and the second display area AA2 all have openings. For ease of description, the openings of the first sub-pixel SP1, the second sub-pixel SP2, the third sub-pixel SP3, the fourth sub-pixel SP4, the fifth sub-pixel SP5 and the sixth sub-pixel SP6 are respectively referred to as the first opening 62A, the second opening 62B, the third opening 62C, the fourth opening 62D, the fifth opening 62E and the sixth opening 62F.
[0124] Reference Figure 6A and Figure 6B In the embodiments disclosed herein, the area of the orthographic projection of the second opening 62B onto the substrate 1 is greater than the area of the orthographic projection of the first opening 62A onto the substrate 1.
[0125] Thus, in the embodiments of this disclosure, since the area of the second opening 62B is larger than the area of the first opening 62A, the actual light-emitting area of the sub-pixel located in the second display area AA2 is greater than the actual light-emitting area of the sub-pixel with the same color located in the first display area AA1. Furthermore, since the actual light-emitting area of a sub-pixel determines its luminance, the luminance of the sub-pixel located in the second display area AA2 is greater than the luminance of the sub-pixel with the same color located in the first display area AA1. Considering that the pixel density of the first display area AA1 is greater than the pixel density of the second display area AA2, in the embodiments of this disclosure, by making the actual light-emitting area of the sub-pixel located in the second display area AA2 greater than the actual light-emitting area of the sub-pixel with the same color located in the first display area AA1, the uniformity of the luminance of each repeating unit in the first display area AA1 and the luminance of each repeating unit in the second display area AA2 is improved, thereby improving display uniformity.
[0126] Furthermore, in the embodiments of this disclosure, the luminous brightness of the sub-pixels located in the second display area AA2 is increased by increasing the actual luminous area. Therefore, it is not necessary to use other methods (such as increasing the driving current) to increase the luminous brightness of the sub-pixels located in the second display area AA2, thereby improving the lifetime of the luminous material of each sub-pixel located in the second display area AA2. In this way, the uniformity of the lifetime of the luminous material of each sub-pixel located in the second display area AA2 and the lifetime of the luminous material of each sub-pixel located in the first display area AA1 is improved.
[0127] Continue to refer to Figure 6A and Figure 6B In the embodiments of this disclosure, the area of the orthographic projection of the fourth opening 62D onto the substrate 1 is larger than the area of the orthographic projection of the third opening 62C onto the substrate 1. Optionally or additionally, the area of the orthographic projection of the sixth opening 62F onto the substrate 1 is larger than the area of the orthographic projection of the fifth opening 62E onto the substrate 1. In this way, the display uniformity between the first display area and the second display area can be further improved, and the uniformity of the lifetime of the light-emitting material of each sub-pixel located in the first display area and the second display area can be improved.
[0128] For example, in Figure 6A and Figure 6B In the embodiment shown, each of the first opening 62A, the second opening 62B, the third opening 62C, the fourth opening 62D, the fifth opening 62E, and the sixth opening 62F has a rectangular shape in its orthographic projection on the substrate 1.
[0129] The rectangle has a first dimension in the row direction X and a second dimension in the column direction Y. For example, the first opening 62A may have a first width W1 (i.e., the first dimension) in the row direction X and a first length L1 (i.e., the second dimension) in the column direction Y, and the second opening 62B may have a second width W2 (i.e., the first dimension) in the row direction X and a second length L2 (i.e., the second dimension) in the column direction Y.
[0130] The first dimension of the second opening 62B is larger than the first dimension of the first opening 62A, and the second dimension of the second opening 62B is larger than the second dimension of the first opening 62A. For example, the second width W2 may be larger than the first width W1, and / or the second length L2 may be larger than the first length L1.
[0131] In some exemplary embodiments, the second width W2 can be equal to (1+n)W1, and the second length L2 can be equal to (1+n)L1, where n is a number greater than 0. Thus, the area of the second opening 62B is (1+n) times the area of the first opening 62A. 2 times.
[0132] For ease of description, n can be referred to as the expansion coefficient in this paper.
[0133] For example, n can be approximately 9%, meaning the second width W2 increases by approximately 9% relative to the first width W1, and the second length L2 increases by approximately 9% relative to the first length L1. Thus, the area of the second opening 62B is approximately 1.19 times the area of the first opening 62A. The inventors have discovered that when n is set to less than or equal to 9%, the risk of color mixing between light emitted from two adjacent sub-pixels can be avoided. In other words, by setting n to approximately 9%, the display uniformity and the uniformity of the luminescent material lifetime between the first and second display areas can be maximized while avoiding color mixing. Furthermore, since the FMM (fine mask) used in the vapor deposition process has a certain tolerance design, the opening of the FMM will be slightly larger than the opening of the corresponding sub-pixel. In the embodiments of this disclosure, the opening defined by the pixel defining layer is slightly expanded outward (e.g., within 9%), which is within the aforementioned tolerance design range. Therefore, in the embodiments of this disclosure, it is not necessary to change the design of the FMM, thereby facilitating the manufacturing process and saving manufacturing costs.
[0134] Optionally, the first dimension W4 of the fourth opening 62D is greater than the first dimension W3 of the third opening 62C, and the second dimension L4 of the fourth opening 62D is greater than the second dimension L3 of the third opening 62C.
[0135] Optionally, the first dimension W6 of the sixth opening 62F is greater than the first dimension W5 of the fifth opening 62E, and the second dimension L6 of the sixth opening 62F is greater than the second dimension L5 of the fifth opening 62E.
[0136] For example, in Figure 6A and Figure 6B In the exemplary embodiment shown, for the first sub-pixel SP1 and the second sub-pixel having the first color, W2 can be equal to (1+n1)W1, and L2 can be equal to (1+n1)L1, where n1 is a number greater than 0. Thus, the area of the second opening 62B is (1+n1) times the area of the first opening 62A. 2 For the third sub-pixel SP3 and the fourth sub-pixel SP4, which have the second color, W4 can be equal to (1+n2)W3, and L4 can be equal to (1+n2)L3, where n2 is a number greater than 0. Thus, the area of the fourth opening 62D is (1+n2) times the area of the third opening 62C. 2 For the fifth sub-pixel SP5 and the sixth sub-pixel SP6, which have the third color, W6 can be equal to (1+n3)W5, and L6 can be equal to (1+n3)L5, where n3 is a number greater than 0. Thus, the area of the sixth opening 62F is (1+n3) times the area of the fifth opening 62E. 2 times.
[0137] For example, n1, n2, and n3 can be equal to each other. That is, the expansion coefficients of sub-pixels of different colors can be set to be the same for each other. For example, they can all be equal to about 9%. In this way, the openings of sub-pixels of different colors expand outwards proportionally, which is beneficial for process implementation.
[0138] Optionally, n1, n2, and n3 can be unequal. That is, the expansion coefficients of sub-pixels of different colors can be set to be different from each other. Optionally, two of n1, n2, and n3 can be equal. This allows for the design of different expansion coefficients for sub-pixels of different colors, increasing design flexibility.
[0139] It should be understood that n1, n2, and n3 can be within the range of 9%, meaning they can be less than or equal to 9%.
[0140] Optionally, in some embodiments of this disclosure, the aforementioned expansion coefficients n1, n2, and n3 can be greater than 0 and less than 30%, for example, they can be 5%, 10%, 15%, 20%, etc.
[0141] Combined with reference Figure 4 and Figure 5For each sub-pixel of each repeating unit, the orthographic projection of the opening 62 onto the substrate 1 falls within the orthographic projection of the anode 41 onto the substrate 1, and the edge of the opening 62 is spaced a certain distance from the edge of the anode 41, such as... Figure 4 As shown in d1. For example, for a sub-pixel of the first repeating unit P1, the distance d1 can be approximately 3.9 micrometers; for a sub-pixel of the second repeating unit P1, the distance d1 can be approximately 2.0 micrometers. Thus, the distance d between the openings 62 between two adjacent sub-pixels in the first repeating unit P1 is approximately 3.8 micrometers greater than the distance d between the openings 62 between two adjacent sub-pixels in the second repeating unit P2. Optionally, in embodiments of this disclosure, the distance d between the openings 62 between two adjacent sub-pixels in the second repeating unit P2 is 4 micrometers or more, for example, between 4 and 20 micrometers. When the distance d between the openings 62 between two adjacent sub-pixels in the second repeating unit P2 is less than 4 micrometers, the risk of color mixing between adjacent sub-pixels is higher. Accordingly, the distance d between the openings 62 between two adjacent sub-pixels in the first repeating unit P1 is at least 3 micrometers greater than the distance d between the openings 62 between two adjacent sub-pixels in the second repeating unit P2.
[0142] Figure 7 This is a plan view of a display panel according to some exemplary embodiments of the present disclosure. (Refer to...) Figure 7 The display panel includes multiple repeating units arranged in an array along the row direction X and the column direction Y. Some repeating units P1 (i.e., first repeating units) are located in a first display area AA1, and other repeating units P2 (i.e., second repeating units) are located in a second display area AA2. The pixel density of the first display area AA1 is greater than the pixel density of the second display area AA2.
[0143] Each repeating unit may include four sub-pixels. Specifically, the first repeating unit P1 may include a first sub-pixel SP1, a third sub-pixel SP3, a fifth sub-pixel SP5, and a seventh sub-pixel SP7, and the second repeating unit P2 may include a second sub-pixel SP2, a fourth sub-pixel SP4, a sixth sub-pixel SP6, and an eighth sub-pixel SP8. Adjacent fifth sub-pixels SP5 and seventh sub-pixels SP7 may form a sub-pixel group, and adjacent sixth sub-pixels SP6 and eighth sub-pixels SP8 may also form a sub-pixel group.
[0144] For example, the fifth sub-pixel SP5, the seventh sub-pixel SP7, the sixth sub-pixel SP6, and the eighth sub-pixel SP8 can be sub-pixels of colors that are sensitive to the human eye, such as green, yellow, or white. For example, compared to the first sub-pixels SP1 to the fourth sub-pixels SP4, the area of each of the fifth sub-pixels SP5, the seventh sub-pixel SP7, the sixth sub-pixel SP6, and the eighth sub-pixel SP8 is relatively small.
[0145] The first sub-pixel SP1, the second sub-pixel SP2, the third sub-pixel SP3, and the fourth sub-pixel SP4 can be sub-pixels of colors that are not sensitive to the human eye. For example, the first sub-pixel SP1 and the second sub-pixel SP2 can be red sub-pixels, and the third sub-pixel SP3 and the fourth sub-pixel SP4 can be blue sub-pixels, but the embodiments of this disclosure are not limited to this. In some exemplary embodiments of this disclosure, the example of the first sub-pixel SP1 and the second sub-pixel SP2 being red sub-pixels and the third sub-pixel SP3 and the fourth sub-pixel SP4 being blue sub-pixels is used for illustration. It should be noted that when the pixel arrangement structure adopts the red-green-blue (RGB) mode, the aforementioned color that is sensitive to the human eye can be green.
[0146] In embodiments according to this disclosure, the visual resolution of the pixel arrangement structure can be improved by arranging the sub-pixels in this way, thereby improving display quality. Furthermore, having the fifth and sixth sub-pixels, as well as the seventh and eighth sub-pixels, of the same color allows the luminescent material layers of two sub-pixels within the same sub-pixel group to be deposited using the same opening in the mask, thereby reducing the process difficulty in fabricating the luminescent material layers in these sub-pixels.
[0147] Similarly, in conjunction with reference Figure 5 The display panel may include: an anode 41 disposed on a substrate 1; a pixel defining layer 6 disposed on the side of the anode 41 away from the substrate 1; a light-emitting layer 42 disposed on the side of the pixel defining layer 6 away from the substrate 1; and a cathode 43 disposed on the side of the light-emitting layer 42 away from the substrate 1.
[0148] The pixel defining layer 6 includes a plurality of openings 62. The plurality of openings 62 are located in a plurality of sub-pixels; for example, one opening 62 is provided in each sub-pixel. Each opening 62 exposes a portion of the anode 41. A portion of the light-emitting layer 42 fills the opening 62 to contact the exposed portion of the anode 41.
[0149] Figure 8A This is a plan view of a first repeating unit located in a first display area of a display panel according to some exemplary embodiments of the present disclosure. Figure 8BThis is a plan view of a second repeating unit located in a second display area of a display panel according to some exemplary embodiments of the present disclosure. To clearly illustrate the shape and size of the opening, Figure 8A and Figure 8B Only the openings of each sub-pixel are shown, while other structures are omitted.
[0150] As described above, the sub-pixels located in the first display area AA1 and the second display area AA2 all have openings. For ease of description, the openings of the first sub-pixel SP1, the second sub-pixel SP2, the third sub-pixel SP3, the fourth sub-pixel SP4, the fifth sub-pixel SP5, the sixth sub-pixel SP6, the seventh sub-pixel SP7 and the eighth sub-pixel SP8 are respectively referred to as the first opening 62A, the second opening 62B, the third opening 62C, the fourth opening 62D, the fifth opening 62E, the sixth opening 62F, the seventh opening 62G and the eighth opening 62H.
[0151] Reference Figure 8A and Figure 8B In the embodiments disclosed herein, the area of the orthographic projection of the second opening 62B onto the substrate 1 is greater than the area of the orthographic projection of the first opening 62A onto the substrate 1.
[0152] Thus, in the embodiments of this disclosure, since the area of the second opening 62B is larger than the area of the first opening 62A, the actual light-emitting area of the sub-pixel located in the second display area AA2 is greater than the actual light-emitting area of the sub-pixel with the same color located in the first display area AA1. Furthermore, since the actual light-emitting area of a sub-pixel determines its luminance, the luminance of the sub-pixel located in the second display area AA2 is greater than the luminance of the sub-pixel with the same color located in the first display area AA1. Considering that the pixel density of the first display area AA1 is greater than the pixel density of the second display area AA2, in the embodiments of this disclosure, by making the actual light-emitting area of the sub-pixel located in the second display area AA2 greater than the actual light-emitting area of the sub-pixel with the same color located in the first display area AA1, the uniformity of the luminance of each repeating unit in the first display area AA1 and the luminance of each repeating unit in the second display area AA2 is improved, thereby improving display uniformity.
[0153] Furthermore, in the embodiments of this disclosure, the luminous brightness of the sub-pixels located in the second display area AA2 is increased by increasing the actual luminous area. Therefore, it is not necessary to use other methods (such as increasing the driving current) to increase the luminous brightness of the sub-pixels located in the second display area AA2, thereby improving the lifetime of the luminous material of each sub-pixel located in the second display area AA2. In this way, the uniformity of the lifetime of the luminous material of each sub-pixel located in the second display area AA2 and the lifetime of the luminous material of each sub-pixel located in the first display area AA1 is improved.
[0154] Continue to refer to Figure 8A and Figure 8B In the embodiments of this disclosure, the area of the orthographic projection of the fourth opening 62D onto the substrate 1 is greater than the area of the orthographic projection of the third opening 62C onto the substrate 1.
[0155] The sum of the areas of the orthographic projections of the sixth opening 62F and the eighth opening 62H onto the substrate 1 is greater than the sum of the areas of the orthographic projections of the fifth opening 62E and the seventh opening 62G onto the substrate 1. In this way, the display uniformity between the first display area and the second display area can be further improved, as well as the uniformity of the lifetime of the light-emitting material of each sub-pixel located in the first display area and the second display area.
[0156] Continue to refer to Figure 8A and Figure 8B Each of the first opening 62A, the second opening 62B, the third opening 62C, and the fourth opening 62D has a hexagonal shape when projected onto the substrate 1.
[0157] Specifically, each hexagon includes three pairs of parallel sides spaced apart from each other, that is, each hexagon includes six sides, namely sl1, sl2, sl3, sl4, sl5, and sl6 in the figure. Among them, sides sl1 and sl2 are spaced apart and parallel to each other, sides sl3 and sl4 are spaced apart and parallel to each other, and sides sl5 and sl6 are spaced apart and parallel to each other. Sides sl1 and sl2 extend along the column direction Y, sides sl3 and sl5 intersect at a vertex o1, and sides sl4 and sl6 intersect at a vertex o2.
[0158] exist Figure 8A In the diagram, the perpendicular distance between sides sl1 and sl2 (which can be called the first width) is W1, and the distance between vertices o1 and o2 (which can be called the first length) is L1. Then, the area S of the orthographic projection of the first opening 62A onto the substrate 1 is... 62A The following formula can be used to calculate:
[0159]
[0160] exist Figure 8B In the diagram, the perpendicular distance between sides sl1 and sl2 (which can be called the second width) is W2, and the distance between vertices o1 and o2 (which can be called the second length) is L2. Then, the area S of the orthographic projection of the second opening 62B onto the substrate 1 is... 62B The following formula can be used to calculate:
[0161]
[0162] It should be noted that W1 and W2 can be regarded as the first dimension in the row direction X, and L1 and L2 can be regarded as the second dimension in the column direction Y.
[0163] For example, the second width W2 may be greater than the first width W1, and / or the second length L2 may be greater than the first length L1.
[0164] In some exemplary embodiments, the second width W2 can be equal to (1+n)W1, and the second length L2 can be equal to (1+n)L1, where n is a number greater than 0. Thus, the area of the second opening 62B is (1+n) times the area of the first opening 62A. 2 times.
[0165] Similarly, n can be approximately 9%, meaning that the second width W2 increases by approximately 9% relative to the first width W1, and the second length L2 increases by approximately 9% relative to the first length L1. Thus, the area of the second opening 62B is approximately 1.19 times the area of the first opening 62A.
[0166] Optionally, the first dimension W4 of the fourth opening 62D is greater than the first dimension W3 of the third opening 62C, and the second dimension L4 of the fourth opening 62D is greater than the second dimension L3 of the third opening 62C.
[0167] For example, in Figure 8A and Figure 8B In the illustrated embodiment, for the first sub-pixel SP1 and the second sub-pixel having the first color, W2 can be equal to (1+n1)W1, and L2 can be equal to (1+n1)L1, where nx is a number greater than 0. Thus, the area of the second opening 62B is (1+n1) times the area of the first opening 62A. 2 For the third sub-pixel SP3 and the fourth sub-pixel SP4, which have the second color, W4 can be equal to (1+n2)W3, and L4 can be equal to (1+n2)L3, where n2 is a number greater than 0. Thus, the area of the second opening 62B is (1+n2) times the area of the first opening 62A. 2 times.
[0168] For example, n1 and n2 can be equal to each other. That is, the expansion coefficients of subpixels of different colors can be set to be the same for each other. For example, they can all be less than or equal to about 9%.
[0169] Optionally, n1 and n2 can be unequal. That is, the expansion coefficients of subpixels of different colors can be set to be different from each other.
[0170] Continue to refer to Figure 8A and Figure 8B Each of the fifth sub-pixel SP5, the sixth sub-pixel SP6, the seventh sub-pixel SP7, and the eighth sub-pixel SP8, when projected onto the substrate 1, can have a pentagonal shape. Each pentagon can include five sides, namely 11, 12, 13, 14, and 15 in the figure, wherein side 11 and side 12 are spaced apart from each other and parallel, one end of side 13 intersects side 11, the other end of side 13 intersects side 12, and side 14 and side 15 intersect at a vertex o3, with vertex o3 opposite to side 13.
[0171] For example, in each repeating unit, there exists a symmetry axis AX extending along the row direction X. The fifth sub-pixel SP5 and the seventh sub-pixel SP7 are symmetrical about this symmetry axis AX, and the sixth sub-pixel SP6 and the eighth sub-pixel SP8 are symmetrical about this symmetry axis AX. It should be understood that the symmetry axis AX is an imaginary axis and not the actual structure of the display panel.
[0172] exist Figure 8A In the diagram, the perpendicular distances between edge 11 and edge 12 (which can be called the first dimension in the row direction X) are W5 and W7, and the perpendicular distances between vertex o3 and edge l3 (which can be called the second dimension in the column direction Y) are L5 and L7. Figure 8B In the equation, the perpendicular distance between edge l1 and edge l2 (which can be called the first dimension in the row direction X) is W6 and W8, and the perpendicular distance between vertex o3 and edge 13 (which can be called the second dimension in the column direction Y) is L6 and L8.
[0173] Similarly, in some exemplary embodiments, W6 can be equal to (1+n3)W5, L6 can be equal to (1+n3)L5, W8 can be equal to (1+n3)W7, and L8 can be equal to (1+n3)L7, where n3 is a number greater than 0. Thus, Figure 8B The sum of the areas of the sixth opening 62F of the sixth sub-pixel SP6 and the eighth opening 62H of the eighth sub-pixel SP8 shown is: Figure 8A The sum of the areas of the fifth opening 62E of the fifth sub-pixel SP5 and the seventh opening 62G of the seventh sub-pixel SP7 shown is (1+n3). 2 times.
[0174] Similarly, for example, n3 can be equal to approximately 9%, that is, W6 increases by approximately 9% relative to W5, and L6 increases by approximately 9% relative to L5. Thus, Figure 8B The sum of the areas of the sixth opening 62F of the sixth sub-pixel SP6 and the eighth opening 62H of the eighth sub-pixel SP8 shown is: Figure 8A The area of the fifth opening 62E of the fifth sub-pixel SP5 and the seventh opening 62G of the seventh sub-pixel SP7 shown is approximately 1.19 times the sum of their areas. In this way, the display uniformity and the uniformity of the luminescent material lifetime between the first and second display areas can be maximized while avoiding color mixing.
[0175] Optionally, n1, n2, and n3 can be equal to each other. That is, the expansion coefficients of subpixels of different colors can be set to be the same for each other. For example, they can all be equal to approximately 9%.
[0176] Optionally, n1, n2, and n3 can be unequal to each other. That is, the expansion coefficients of subpixels of different colors can be set to be different from each other. Optionally, two of n1, n2, and n3 can be equal to each other.
[0177] Similarly, in some embodiments of this disclosure, the aforementioned expansion coefficients n1, n2, and n3 can be greater than 0 and less than 30%, for example, they can be 5%, 10%, 15%, 20%, etc.
[0178] In embodiments of this disclosure, the distance d between the openings 62 of two adjacent sub-pixels in the second repeating unit P2 is 4 micrometers or more; that is, in one second repeating unit, the minimum distance between the edges of the openings of two adjacent sub-pixels is 4 micrometers or more, for example, between 4 and 20 micrometers. When the distance d between the openings 62 of two adjacent sub-pixels in the second repeating unit P2 is less than 4 micrometers, the risk of color mixing between adjacent sub-pixels is higher. Correspondingly, the distance d between the openings 62 of two adjacent sub-pixels in the first repeating unit P1 is at least 3 micrometers larger than the distance d between the openings 62 of two adjacent sub-pixels in the second repeating unit P2.
[0179] Figure 9 This is a plan view of a display panel according to some exemplary embodiments of the present disclosure. Figure 10A This is a plan view of a first repeating unit located in a first display area of a display panel according to some exemplary embodiments of the present disclosure. Figure 10B This is a plan view of a second repeating unit located in a second display area of a display panel according to some exemplary embodiments of the present disclosure. To clearly illustrate the shape and size of the opening, Figure 10A and Figure 10BOnly the openings of each sub-pixel are shown, while other structures are omitted.
[0180] The following will combine Figure 9 , Figure 10A and Figure 10B The special features of this embodiment are described above. It should be understood that other structures and features of this embodiment can be referred to in the above description.
[0181] Reference Figure 9 The display panel includes multiple repeating units arranged in an array along the row direction X and the column direction Y. Some repeating units P1 (i.e., first repeating units) are located in the first display area AA1, and other repeating units P2 (i.e., second repeating units) are located in the second display area AA2.
[0182] Each repeating unit may include 4 sub-pixels. Specifically, the first repeating unit P1 may include the first sub-pixel SP1, the third sub-pixel SP3, the fifth sub-pixel SP5, and the seventh sub-pixel SP7, and the second repeating unit P2 may include the second sub-pixel SP2, the fourth sub-pixel SP4, the sixth sub-pixel SP6, and the eighth sub-pixel SP8.
[0183] For example, the fifth sub-pixel SP5, the seventh sub-pixel SP7, the sixth sub-pixel SP6, and the eighth sub-pixel SP8 can be sub-pixels of colors that are sensitive to the human eye, such as green, yellow, or white. For example, compared to the first sub-pixels SP1 to the fourth sub-pixels SP4, the area of each of the fifth sub-pixels SP5, the seventh sub-pixel SP7, the sixth sub-pixel SP6, and the eighth sub-pixel SP8 is relatively small.
[0184] The first sub-pixel SP1, the second sub-pixel SP2, the third sub-pixel SP3, and the fourth sub-pixel SP4 can be sub-pixels of colors that are not sensitive to the human eye. For example, the first sub-pixel SP1 and the second sub-pixel SP2 can be red sub-pixels, and the third sub-pixel SP3 and the fourth sub-pixel SP4 can be blue sub-pixels, but the embodiments of this disclosure are not limited to this. In some exemplary embodiments of this disclosure, the example of the first sub-pixel SP1 and the second sub-pixel SP2 being red sub-pixels and the third sub-pixel SP3 and the fourth sub-pixel SP4 being blue sub-pixels is used for illustration. It should be noted that when the pixel arrangement structure adopts the red-green-blue (RGB) mode, the aforementioned color that is sensitive to the human eye can be green.
[0185] In embodiments according to this disclosure, by arranging the sub-pixels in this way, the visual resolution of the pixel arrangement structure can be improved, thereby improving the display quality.
[0186] As described above, the sub-pixels located in the first display area AA1 and the second display area AA2 all have openings. For ease of description, the openings of the first sub-pixel SP1, the second sub-pixel SP2, the third sub-pixel SP3, the fourth sub-pixel SP4, the fifth sub-pixel SP5, the sixth sub-pixel SP6, the seventh sub-pixel SP7 and the eighth sub-pixel SP8 are respectively referred to as the first opening 62A, the second opening 62B, the third opening 62C, the fourth opening 62D, the fifth opening 62E, the sixth opening 62F, the seventh opening 62G and the eighth opening 62H.
[0187] Reference Figure 9 Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, and multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y. The distribution density of the first repeating units P1 is greater than the distribution density of the second repeating units P2.
[0188] For a second repeating unit P2, its sixth sub-pixel SP6 and eighth sub-pixel SP8 are located in the same column and are positioned on either side of the fourth sub-pixel SP4 along the column direction Y. The second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth / eighth sub-pixels SP6 / SP8 are each located in three columns, that is, the second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth / eighth sub-pixels SP6 / SP8 are arranged sequentially along the row direction X. The second sub-pixel SP2 and the sixth sub-pixel SP6 are located in the same row. The second / eighth sub-pixels SP2 / SP6, the fourth sub-pixel SP4, and the eighth sub-pixel SP8 are arranged sequentially along the column direction Y.
[0189] The second repeating unit P2 is aligned with some of the first repeating units P1 in the column direction Y. For example, the second repeating unit P2 is only aligned with the first repeating units P1 in odd-numbered columns in the column direction Y, and no second repeating unit P2 is set in the column containing the first repeating units P1 in even-numbered columns. Of course, it can also be said that the second repeating unit P2 is only aligned with the first repeating units P1 in even-numbered columns in the column direction Y, and no second repeating unit P2 is set in the column containing the first repeating units P1 in odd-numbered columns. Specifically, in two adjacent rows of second repeating units P2, one second repeating unit P2 in one row and another second repeating unit P2 adjacent to it in the other row are spaced apart in the row direction X, and the distance between them is approximately equal to the size (i.e., width) of a first repeating unit along the row direction X.
[0190] Continue to refer to Figure 9 In the second repeating unit P2 in the same row, two adjacent second repeating units P2 are spaced apart in the row direction X, and the distance between them is approximately equal to the size of the three first repeating units along the row direction X.
[0191] Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, and multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y. Correspondingly, the sub-pixels included in each repeating unit P1 and P2 are also arranged in an array along the row direction X and the column direction Y. In repeating units P1 and P2 in the same column, the first sub-pixel SP1 and the second sub-pixel SP2 are located in the same column, the third sub-pixel SP3 and the fourth sub-pixel SP4 are located in the same column, the fifth sub-pixel SP5 and the seventh sub-pixel SP7, and the sixth sub-pixel SP6 and the eighth sub-pixel SP8 are located in the same column.
[0192] For example, in the first display area AA1, the first repeating unit P1 includes first sub-pixels SP1 arranged in an array along the row direction X and the column direction Y. In the first repeating unit P1 in the same row, two adjacent first sub-pixels SP1 are separated by two columns of sub-pixels, that is, separated by a column of third sub-pixels SP3 and a column of fifth / seventh sub-pixels SP5 / SP7.
[0193] For example, in the second display area AA2, the second repeating unit P2 includes second sub-pixels SP2 arranged in an array along the row direction X and the column direction Y. In the second repeating unit P2 in the same row, there are eleven columns of sub-pixels between two adjacent second sub-pixels SP2, that is, a column of fourth sub-pixel SP4, a column of sixth / eighth sub-pixels SP6 / SP8, a column of first sub-pixel SP1, a column of third sub-pixel SP3, a column of fifth / seventh sub-pixels SP5 / SP7, a column of first sub-pixel SP1, a column of third sub-pixel SP3, a column of fifth / seventh sub-pixels SP5 / SP7, a column of first sub-pixel SP1, a column of third sub-pixel SP3, and a column of fifth / seventh sub-pixels SP5 / SP7.
[0194] Continue to refer to Figure 9 The display panel also includes a plurality of spacers. For ease of description, the spacer located in the first display area AA1 is described as the first spacer PS1, and the spacer located in the second display area AA2 is described as the second spacer PS2.
[0195] Multiple first spacers PS1 are arranged in an array along the row direction X and column direction Y in a first display area AA1, and multiple second spacers PS2 are arranged in an array along the row direction X and column direction Y in a second display area AA2. The distribution density of the first spacers PS1 is greater than the distribution density of the second spacers PS2. For example, the distribution density of the second spacers PS2 can be approximately 1 / 6 to 1 / 3 of the distribution density of the first spacers PS1. For example, as... Figure 9 The distribution density of the second septum PS2 can be approximately 1 / 4 of the distribution density of the first septum PS1.
[0196] The second spacer PS2 is only provided in the area where the second repeating unit P2 is located. That is, the second spacer PS2 is not provided in the light-transmitting area TRA where there is no second repeating unit P2.
[0197] For example, the number of second septum PS2 is no greater than the number of second repeating units P2.
[0198] Optionally, the number of second spacers PS2 can be equal to the number of second repeating units P2; for example, one and only one second spacer PS2 is provided in each second repeating unit P2. Optionally, as... Figure 9 As shown, the number of second spacers PS2 can be less than the number of second repeating units P2. For example, some second repeating units P2 may have one and only one second spacer PS2, while other second repeating units P2 may not have a second spacer PS2.
[0199] Continue to refer to Figure 9 In the second display area AA2, some second spacers PS2 are disposed between the second sub-pixel SP2 and the sixth sub-pixel SP6. For ease of description, the second spacers PS2 disposed between the second sub-pixel SP2 and the sixth sub-pixel SP6 are referred to as first sub-spacers PS21. For multiple first sub-spacers PS21 located in the same column, the lines connecting these first sub-spacers PS21 pass through the fourth sub-pixel SP4, that is, they are aligned with the fourth sub-pixel SP4 in the column direction Y.
[0200] In the second display area AA2, additional second spacers PS2 are disposed on one side of the fourth sub-pixel SP4 and aligned with the second sub-pixel SP2 in the column direction Y. For ease of description, the second spacers PS2 disposed on one side of the fourth sub-pixel SP4 are referred to as second sub-spacers PS22. For multiple second sub-spacers PS22 located in the same column, the lines connecting these second sub-spacers PS22 pass through the second sub-pixel SP2.
[0201] If Figure 9 The XY coordinate system is rotated counterclockwise by 45°, meaning the column direction Y extends to the upper left at a 45° angle relative to the horizontal line, and the row direction X extends to the upper right at a 45° angle relative to the horizontal line. At this point, the second spacers in the same column are of the same type; that is, within the same column, they are either the first sub-spacer PS21 or the second sub-spacer PS22. In adjacent columns, the second spacers are of different types; that is, in two adjacent columns, one column has the first sub-spacer PS21, and the other has the second sub-spacer PS22. In other words, in a diagonal column direction (e.g., at a certain angle relative to the column direction Y, such as 45°)... Figure 9In the direction Y1 shown in the middle, the second spacers located in the same diagonal column are either the first sub-spacer PS21 or the second sub-spacer PS22. Among the second spacers located in two adjacent diagonal columns, one column is the first sub-spacer PS21 and the other column is the second sub-spacer PS22.
[0202] Reference Figure 10A and Figure 10B In the embodiments disclosed herein, the area of the orthographic projection of the second opening 62B onto the substrate 1 is greater than the area of the orthographic projection of the first opening 62A onto the substrate 1.
[0203] The area of the orthographic projection of the fourth opening 62D onto the substrate 1 is greater than the area of the orthographic projection of the third opening 62C onto the substrate 1.
[0204] The sum of the areas of the orthographic projections of the sixth opening 62F and the eighth opening 62H onto the substrate 1 is greater than the sum of the areas of the orthographic projections of the fifth opening 62E and the seventh opening 62G onto the substrate 1. For example, the area of the orthographic projection of the sixth opening 62F onto the substrate 1 is greater than the area of the orthographic projection of the fifth opening 62E onto the substrate 1, and the area of the orthographic projection of the eighth opening 62H onto the substrate 1 is greater than the area of the orthographic projection of the seventh opening 62G onto the substrate 1.
[0205] In other words, the openings of each sub-pixel in the second repeating unit P2 are wider than the openings of the corresponding sub-pixels in the first repeating unit P1. For a detailed description of this expansion, please refer to the above text. Figures 1 to 8B The description will not be repeated here.
[0206] In this way, the display uniformity between the first display area and the second display area can be further improved, as well as the uniformity of the lifespan of the light-emitting materials of each sub-pixel in the first display area and the second display area can be improved.
[0207] Figure 11 This is a plan view of a display panel according to some exemplary embodiments of the present disclosure. Figure 12A This is a plan view of a first repeating unit located in a first display area of a display panel according to some exemplary embodiments of the present disclosure. Figure 12B This is a plan view of a second repeating unit located in a second display area of a display panel according to some exemplary embodiments of the present disclosure. To clearly illustrate the shape and size of the opening, Figure 12A and Figure 12B Only the openings of each sub-pixel are shown, while other structures are omitted.
[0208] The following will combine Figure 11 , Figure 12A and Figure 12BThe special features of this embodiment are described above. It should be understood that other structures and features of this embodiment can be referred to in the above description.
[0209] Reference Figure 11 The display panel includes multiple repeating units arranged in an array along the row direction X and the column direction Y. Some repeating units P1 (i.e., first repeating units) are located in the first display area AA1, and other repeating units P2 (i.e., second repeating units) are located in the second display area AA2.
[0210] Each repeating unit may include 4 sub-pixels. Specifically, the first repeating unit P1 may include the first sub-pixel SP1, the third sub-pixel SP3, the fifth sub-pixel SP5, and the seventh sub-pixel SP7, and the second repeating unit P2 may include the second sub-pixel SP2, the fourth sub-pixel SP4, the sixth sub-pixel SP6, and the eighth sub-pixel SP8.
[0211] Reference Figure 11 Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, and multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y. The distribution density of the first repeating units P1 is greater than the distribution density of the second repeating units P2.
[0212] For a second repeating unit P2, its sixth sub-pixel SP6 and eighth sub-pixel SP8 are located in the same column and are positioned on the same side of the fourth sub-pixel SP4 along the column direction Y. The sixth sub-pixel SP6 and eighth sub-pixel SP8 are spaced apart along the column direction Y. The sixth sub-pixel SP6 and eighth sub-pixel SP8 are positioned on the same side of the second sub-pixel SP2 along the row direction X. The second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth / eighth sub-pixels SP6 / SP8 are each located in three columns, that is, the second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth / eighth sub-pixels SP6 / SP8 are arranged sequentially along the row direction X. The combination of the sixth sub-pixel SP6 and the eighth sub-pixel SP8 is located in the same row as the second sub-pixel SP2. The fourth sub-pixel SP4 and the second / sixth / eighth sub-pixels SP2 / SP6 / SP8 are arranged sequentially along the column direction Y.
[0213] The second repeating unit P2 is aligned with some of the first repeating units P1 in the column direction Y. For example, the second repeating unit P2 is only aligned with the first repeating units P1 in odd-numbered columns in the column direction Y, and no second repeating unit P2 is set in the column containing the first repeating units P1 in even-numbered columns. Of course, it can also be said that the second repeating unit P2 is only aligned with the first repeating units P1 in even-numbered columns in the column direction Y, and no second repeating unit P2 is set in the column containing the first repeating units P1 in odd-numbered columns. Specifically, in two adjacent rows of second repeating units P2, one second repeating unit P2 in one row and another second repeating unit P2 adjacent to it in the other row are separated by one repeating unit in the row direction X.
[0214] Continue to refer to Figure 11 In the second repeating unit P2 of the same row, two adjacent second repeating units P2 are spaced three repeating units apart in the row direction X.
[0215] Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, and multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y. Correspondingly, the sub-pixels included in each repeating unit P1 and P2 are also arranged in an array along the row direction X and the column direction Y. In repeating units P1 and P2 in the same column, the first sub-pixel SP1 and the second sub-pixel SP2 are located in the same column, the third sub-pixel SP3 and the fourth sub-pixel SP4 are located in the same column, the fifth sub-pixel SP5 and the seventh sub-pixel SP7, and the sixth sub-pixel SP6 and the eighth sub-pixel SP8 are located in the same column.
[0216] For example, in the first display area AA1, the first repeating unit P1 includes first sub-pixels SP1 arranged in an array along the row direction X and the column direction Y. In the first repeating unit P1 in the same row, two adjacent first sub-pixels SP1 are separated by two columns of sub-pixels, that is, separated by a column of third sub-pixels SP3 and a column of fifth / seventh sub-pixels SP5 / SP7.
[0217] For example, in the second display area AA2, the second repeating unit P2 includes second sub-pixels SP2 arranged in an array along the row direction X and the column direction Y. In the second repeating unit P2 in the same row, there are eleven columns of sub-pixels between two adjacent second sub-pixels SP2, that is, a column of fourth sub-pixel SP4, a column of sixth / eighth sub-pixels SP6 / SP8, a column of first sub-pixel SP1, a column of third sub-pixel SP3, a column of fifth / seventh sub-pixels SP5 / SP7, a column of first sub-pixel SP1, a column of third sub-pixel SP3, a column of fifth / seventh sub-pixels SP5 / SP7, a column of first sub-pixel SP1, a column of third sub-pixel SP3, and a column of fifth / seventh sub-pixels SP5 / SP7.
[0218] Continue to refer to Figure 11 The display panel also includes a plurality of spacers. For ease of description, the spacer located in the first display area AA1 is described as the first spacer PS1, and the spacer located in the second display area AA2 is described as the second spacer PS2.
[0219] Multiple first spacers PS1 are arranged in an array along the row direction X and column direction Y in a first display area AA1, and multiple second spacers PS2 are arranged in an array along the row direction X and column direction Y in a second display area AA2. The distribution density of the first spacers PS1 is greater than the distribution density of the second spacers PS2. For example, the distribution density of the second spacers PS2 can be approximately 1 / 6 to 1 / 3 of the distribution density of the first spacers PS1. For example, as... Figure 11 The distribution density of the second septum PS2 can be approximately one-third of the distribution density of the first septum PS1.
[0220] The second spacer PS2 is only provided in the area where the second repeating unit P2 is located. That is, the second spacer PS2 is not provided in the light-transmitting area TRA where there is no second repeating unit P2.
[0221] For example, the number of second septum PS2 is no greater than the number of second repeating units P2.
[0222] Optionally, the number of second spacers PS2 can be equal to the number of second repeating units P2; for example, one and only one second spacer PS2 is provided in each second repeating unit P2. Optionally, as... Figure 11 As shown, the number of second spacers PS2 can be less than the number of second repeating units P2. For example, some second repeating units P2 may have one and only one second spacer PS2, while other second repeating units P2 may not have a second spacer PS2.
[0223] Continue to refer to Figure 11 In the second display area AA2, some second spacers PS2 are positioned between the combination of the sixth sub-pixel SP6 and the eighth sub-pixel SP8 and the second sub-pixel SP2. For ease of description, these second spacers PS2 are referred to as first sub-spacers PS21. For multiple first sub-spacers PS21 located in the same column, the lines connecting these first sub-spacers PS21 pass through the fourth sub-pixel SP4, that is, they are aligned with the fourth sub-pixel SP4 in the column direction Y.
[0224] In the second display area AA2, additional second spacers PS2 are disposed to one side of the fourth sub-pixel SP4 and aligned in the column direction Y with the combination of the sixth sub-pixel SP6 and the eighth sub-pixel SP8. For ease of description, these second spacers are referred to as second sub-spacers PS22. For multiple second sub-spacers PS22 located in the same column, the lines connecting these second sub-spacers PS22 pass through the sixth sub-pixel SP6 and the eighth sub-pixel SP8.
[0225] Similarly, if Figure 11 The XY coordinate system is rotated counterclockwise by 45°, meaning the column direction Y extends to the upper left at a 45° angle relative to the horizontal line, and the row direction X extends to the upper right at a 45° angle relative to the horizontal line. At this point, the second spacers in the same column are of the same type; that is, within the same column, they are either the first sub-spacer PS21 or the second sub-spacer PS22. In adjacent columns, the second spacers are of different types; that is, in two adjacent columns, one column has the first sub-spacer PS21, and the other has the second sub-spacer PS22. In other words, in a diagonal column direction (e.g., at a certain angle relative to the column direction Y, such as 45°)... Figure 11 In the direction Y1 shown in the middle, the second spacers located in the same diagonal column are either the first sub-spacer PS21 or the second sub-spacer PS22. Among the second spacers located in two adjacent diagonal columns, one column is the first sub-spacer PS21 and the other column is the second sub-spacer PS22.
[0226] Reference Figure 12A and Figure 12B In the embodiments disclosed herein, the area of the orthographic projection of the second opening 62B onto the substrate 1 is greater than the area of the orthographic projection of the first opening 62A onto the substrate 1.
[0227] The area of the orthographic projection of the fourth opening 62D onto the substrate 1 is greater than the area of the orthographic projection of the third opening 62C onto the substrate 1.
[0228] The sum of the areas of the orthographic projections of the sixth opening 62F and the eighth opening 62H onto the substrate 1 is greater than the sum of the areas of the orthographic projections of the fifth opening 62E and the seventh opening 62G onto the substrate 1. For example, the area of the orthographic projection of the sixth opening 62F onto the substrate 1 is greater than the area of the orthographic projection of the fifth opening 62E onto the substrate 1, and the area of the orthographic projection of the eighth opening 62H onto the substrate 1 is greater than the area of the orthographic projection of the seventh opening 62G onto the substrate 1.
[0229] In other words, the openings of each sub-pixel in the second repeating unit P2 are wider than the openings of the corresponding sub-pixels in the first repeating unit P1. For a detailed description of this expansion, please refer to the above text. Figures 1 to 8BThe description will not be repeated here.
[0230] In this way, the display uniformity between the first display area and the second display area can be further improved, as well as the uniformity of the lifespan of the light-emitting materials of each sub-pixel in the first display area and the second display area can be improved.
[0231] Figure 13 This is a plan view of a display panel according to some exemplary embodiments of the present disclosure. Figure 14A This is a plan view of a first repeating unit located in a first display area of a display panel according to some exemplary embodiments of the present disclosure. Figure 14B This is a plan view of a second repeating unit located in a second display area of a display panel according to some exemplary embodiments of the present disclosure. To clearly illustrate the shape and size of the opening, Figure 14A and Figure 14B Only the openings of each sub-pixel are shown, while other structures are omitted.
[0232] The following will combine Figure 13 , Figure 14A and Figure 14B The special features of this embodiment are described above. It should be understood that other structures and features of this embodiment can be referred to in the above description.
[0233] Reference Figure 13 The display panel includes multiple repeating units arranged in an array along the row direction X and the column direction Y. Some repeating units P1 (i.e., first repeating units) are located in the first display area AA1, and other repeating units P2 (i.e., second repeating units) are located in the second display area AA2.
[0234] Some first repeating units P1 may include four sub-pixels, namely the first sub-pixel SP1, the third sub-pixel SP3, the fifth sub-pixel SP5, and the seventh sub-pixel SP7. The second repeating unit P2 may include three sub-pixels, namely the second sub-pixel SP2, the fourth sub-pixel SP4, and the sixth sub-pixel SP6.
[0235] Optionally, for the plurality of first repeating units P1 disposed near the edge of the second display area AA2, for example, referring to Figure 13For a row of first repeating units P1 near the lower edge of the second display area AA2, each first repeating unit P1 may include three sub-pixels: a first sub-pixel SP1, a third sub-pixel SP3, and a fifth sub-pixel SP5. That is, in this row of first repeating units P1, each first repeating unit P1 does not include the aforementioned seventh sub-pixel SP7. The fifth sub-pixel SP5 is further away from the adjacent row of second repeating units P2 than the first sub-pixel SP1 or the third sub-pixel SP3; that is, the distance between the fifth sub-pixel SP5 and the adjacent row of second repeating units P2 along the column direction Y is greater than the distance between the first sub-pixel SP1 or the third sub-pixel SP3 and the adjacent row of second repeating units P2 along the column direction Y. Thus, in a row of first repeating units P1 near the lower edge of the second display area AA2, a recessed structure is formed at each fifth sub-pixel SP5. In this way, the distance between the fifth sub-pixel SP5 and the adjacent row of second repeating units P2 can be increased, thereby increasing the area of the light-transmitting region TRA and increasing the transmittance.
[0236] Reference Figure 13 Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, and multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y. The distribution density of the first repeating units P1 is greater than the distribution density of the second repeating units P2.
[0237] For a second repeating unit P2, the second sub-pixel SP2, the sixth sub-pixel SP6 and the fourth sub-pixel SP4 are located in the same row and are arranged in the above order along the row direction X.
[0238] There is a blank row between two adjacent rows of second repeating units P2, meaning that no second repeating unit P2 is set in that row. In other words, the spacing between two adjacent rows of second repeating units P2 is equal to the dimension of one second repeating unit P2 along the column direction Y. This increases the area of the light-transmitting region TRA.
[0239] Continue to refer to Figure 13 The display panel also includes a plurality of spacers. For ease of description, the spacer located in the first display area AA1 is described as the first spacer PS1, and the spacer located in the second display area AA2 is described as the second spacer PS2.
[0240] Multiple first spacers PS1 are arranged in an array along the row direction X and column direction Y in a first display area AA1, and multiple second spacers PS2 are arranged in an array along the row direction X and column direction Y in a second display area AA2. The distribution density of the first spacers PS1 is greater than the distribution density of the second spacers PS2. For example, the distribution density of the second spacers PS2 can be approximately 1 / 4 to 1 / 2 of the distribution density of the first spacers PS1. For example, as... Figure 13 The distribution density of the second septum PS2 can be approximately half that of the distribution density of the first septum PS1.
[0241] The second spacer PS2 is only provided in the area where the second repeating unit P2 is located. That is, the second spacer PS2 is not provided in the light-transmitting area TRA where there is no second repeating unit P2.
[0242] For example, the number of second septum PS2 is no greater than the number of second repeating units P2.
[0243] Optionally, the number of second spacers PS2 can be equal to the number of second repeating units P2; for example, one and only one second spacer PS2 is provided in each second repeating unit P2. Optionally, as... Figure 13 As shown, the number of second spacers PS2 can be less than the number of second repeating units P2. For example, some second repeating units P2 may have one and only one second spacer PS2, while other second repeating units P2 may not have a second spacer PS2.

Some repeating units P1 (i.e., the first repeating units) are located in the first display area AA1, and other repeating units (including the second repeating unit P2 and the third repeating unit P3) are located in the second display area AA2.
[0253] The first repeating unit P1 may include a first sub-pixel SP1, a third sub-pixel SP3, a fifth sub-pixel SP5, and a seventh sub-pixel SP7. The second repeating unit P2 may include a second sub-pixel SP2 and a sixth sub-pixel SP6, and the third repeating unit may include a fourth sub-pixel SP4 and an eighth sub-pixel SP8.
[0254] Reference Figure 15 Multiple first repeating units P1 are arranged in an array along the row direction X and the column direction Y, multiple second repeating units P2 are arranged in an array along the row direction X and the column direction Y, and multiple third repeating units P3 are arranged in an array along the row direction X and the column direction Y. The distribution density of the first repeating units P1 is greater than the distribution density of the second repeating units P2, and the distribution density of the first repeating units P1 is greater than the distribution density of the third repeating units P3.
[0255] The row containing the second repeating unit P2 and the row containing the third repeating unit P3 are alternately arranged along the column direction Y. The column containing the second repeating unit P2 and the column containing the third repeating unit P3 are alternately arranged along the row direction X, and the distance between them is approximately equal to the size of the first repeating unit P1 along the row direction X.

The distribution density of the first spacers PS1 is greater than the distribution density of the second spacers PS2. For example, the distribution density of the second spacers PS2 can be approximately 1 / 6 to 1 / 3 of the distribution density of the first spacers PS1. For example, as... Figure 15 The distribution density of the second septum PS2 can be approximately 1 / 6 of the distribution density of the first septum PS1.
[0260] The second spacer PS2 is only provided in the area where the second repeating unit P2 is located. That is, the second spacer PS2 is not provided in the light-transmitting area TRA where there is no second repeating unit P2.
[0261] For example, the number of second septum PS2 is no greater than the number of second repeating units P2.
[0262] Optionally, the number of second spacers PS2 can be equal to the number of second repeating units P2; for example, one and only one second spacer PS2 is provided in each second repeating unit P2. Optionally, as... Figure 15 As shown, the number of second spacers PS2 can be less than the number of second repeating units P2. For example, some second repeating units P2 may have one and only one second spacer PS2, while other second repeating units P2 may not have a second spacer PS2.
[0263] Reference Figures 16A to 16C In the embodiments disclosed herein, the area of the orthographic projection of the second opening 62B onto the substrate 1 is greater than the area of the orthographic projection of the first opening 62A onto the substrate 1.

[0266] The area of the eighth opening 62H projected onto the substrate 1 is greater than the area of the seventh opening 62G projected onto the substrate 1.
[0267] In other words, the openings of each sub-pixel in the second repeating unit P2 and the third repeating unit P3 are wider than the openings of the corresponding sub-pixels in the first repeating unit P1. For a detailed description of this expansion, please refer to the above text. Figures 1 to 8B The description will not be repeated here.
[0268] In this way, the display uniformity between the first display area and the second display area can be further improved, as well as the uniformity of the lifetime of the light-emitting material of each sub-pixel located in the first and second display areas. In the above embodiments, rectangular, hexagonal, and pentagonal shapes were used as examples to describe each sub-pixel. However, the embodiments of this disclosure are not limited to these shapes. For example, the shape of the orthographic projection of a sub-pixel onto the substrate can include, but is not limited to, the following shapes: trapezoidal, rhomboid, circular, elliptical, approximately rectangular, etc., where approximately rectangular includes, for example, rounded rectangles, but is not limited to these. Correspondingly, the shape of the orthographic projection of the opening of each sub-pixel onto the substrate can include, but is not limited to, the following shapes: rectangular, hexagonal, pentagonal, trapezoidal, rhomboid, circular, elliptical, approximately rectangular, etc.
[0269] It should be noted that in the above embodiments, the shape of the spacer in the plan view is shown as a rectangle. However, the embodiments of this disclosure are not limited to this. The shape of the spacer in the plan view can also be other shapes, such as circles, squares, etc.
[0270] Return to reference Figure 5 In some exemplary embodiments of this disclosure, the pixel defining layer 6 may be made of one or more of the following materials: polyimide, silicon oxide, silicon nitride, and photoresist. For example, the pixel defining layer 6 may be formed solely using one of the above materials. Optionally, the pixel defining layer 6 may be composed of multiple layers of films stacked together, wherein each layer is formed of one or more of the above materials.
[0271] Reference Figure 17 In some exemplary embodiments of this disclosure, the pixel defining layer 6 described above can be formed using the following manufacturing method.
[0272] In step S101, a pixel defining material film layer can be formed. For example, the pixel defining material film layer can be formed by film formation methods such as coating, evaporation, sputtering, and chemical vapor deposition.
[0273] In step S102, a pixel defining layer 6 with an opening 62 can be formed by a patterning process.
[0274] For example, in this patterning process, photoresist can be applied, followed by exposure and development, with the exposed area corresponding to the location where the opening 62 is to be formed. Then, dry etching is performed to remove the pixel-defining material at the exposed area, forming the opening 62. Finally, the remaining photoresist is stripped off.
[0275] Alternatively, if the pixel defining layer is made of photoresist material, dry etching can be omitted in this step.
[0276] Return to reference Figure 1 and Figure 2 At least some embodiments of this disclosure also provide a display device. This display device may include a display panel and an image sensor 2 (e.g., a camera) as described above.
[0277] As described above, the display panel has a first display area and a second display area, the pixel density of the first display area being greater than the pixel density of the second display area. The image sensor 2 is located on the side of the substrate 1 facing away from the pixel array, with its photosensitive surface facing the display panel. The orthographic projection of the image sensor 2 onto the substrate 1 overlaps with the orthographic projection of the second display area AA2 onto the substrate 1, for example, it is located within the orthographic projection of the second display area AA2 onto the substrate 1. This allows imaging using light passing through the second display area, thereby enabling the under-display camera function.
[0278] Image sensor 2 can employ a structure known in the art, such as a complementary metal-oxide-semiconductor (CMOS) image sensor or a charge-coupled device (CCD) image sensor. Image sensor 2 can be electrically connected to an image processor. In addition to the image sensor, to achieve better imaging results, the imaging module including the image sensor may also include a lens assembly, and the lens assembly and the image sensor can be arranged sequentially along the optical axis of the lens assembly in a direction perpendicular to the substrate 1.
