For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.
[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.
[0046] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0047] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0048] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.
[0049] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:
[0050] As described in the background art, the display panel in the related art is prone to poor display when switched to the anti-peeping mode. The inventors have found that this is because when the display panel is switched to the anti-peeping display mode, the spacing between the displayed sub-pixels will increase, which will easily produce grid patterns, resulting in poor display when the display panel is switched to the anti-peeping mode. For details, see Figure 1 , Figure 1Image A in the figure represents the sub-pixels that emit light in the normal display mode. In image A, sub-pixels R1, R2, G1, G2, B1, and B2 all emit light. Image B represents the sub-pixels that emit light in the anti-peeping display mode. In image B, sub-pixels R2, G2, and B2 emit light, while sub-pixels R1, G1, and B1 do not emit light (the sub-pixels that do not emit light are hidden in image B). In the normal display mode, in two adjacent pixel units in the first direction X, the minimum spacing between blue sub-pixels that are in the light-emitting state and have the same light-emitting color is a1', and in the same pixel unit in the first direction X, the minimum spacing between red sub-pixels and blue sub-pixels that are in the light-emitting state and have different light-emitting colors is a2'. In the anti-peeping display mode, in two pixel units in the first direction X, the minimum spacing between blue sub-pixels that are in the light-emitting state and have the same light-emitting color is b1', and in the same pixel unit in the first direction X, the minimum spacing between red sub-pixels and blue sub-pixels that are in the light-emitting state and have the same light-emitting color is b2'. It can be seen that b1'>a1', b2'>a2'. It can be seen that, in the display panel of the related art, in the anti-peeping display mode, the spacing between adjacent sub-pixels in the light-emitting state becomes larger.
[0051] In order to solve at least one of the above technical problems, the embodiments of the present application provide a display panel and a display device. The embodiments of the display panel and the display device will be described below in conjunction with the accompanying drawings.
[0052] Figure 2 , Figure 4 , Figure 6 , Figure 8 Schematic diagrams showing some pixel arrangement structures of the display panel provided by the embodiments of the present application are shown, wherein: Figure 3 , Figure 5 , Figure 7 , Fig. 9 It shows that the Figure 2 , Figure 4 , Figure 6 , Figure 8 Schematic diagram of the pixel arrangement structure in two modes, where: Figure 3 , Figure 5 , Figure 7 , Fig. 9 The images A all represent sub-pixels that emit light in the first mode, Figure 3 , Figure 5 , Figure 7 , Fig. 9 The images B all represent sub-pixels that emit light in the second mode, and Figure 3 , Figure 5 , Figure 7 , Fig. 9The non-luminous sub-pixels are hidden in the image B. In addition, in the drawings of the present application, the sub-pixels filled with the same pattern represent the sub-pixels with the same luminous color, and the sub-pixels filled with different patterns represent the sub-pixels with different luminous colors.
[0053] like Figure 3 , Figure 5 , Figure 7 , Fig. 9 As shown, the display panel provided in the embodiment of the present application includes a plurality of pixel units 10, and the plurality of pixel units 10 are distributed in an array in the intersecting first direction X and second direction Y. It should be noted that: Figure 3 , Figure 5 , Figure 7 , Fig. 9 Nine pixel units 10 distributed in a 3*3 pattern are shown, but this does not limit the number of pixel units, and the number of pixel units can be set according to actual needs.
[0054] The pixel unit 10 includes an A pixel 11 and a B pixel 12, wherein the light emitting visual angle of the A pixel 11 is greater than the light emitting viewing angle of the B pixel 12. The A pixel 11 is a pixel with a wide viewing angle, and the B pixel 12 is a pixel with a narrow viewing angle.
[0055] Exemplarily, a light-guiding structure may be provided on the side where the pixel emits light. For example, the light-guiding structure corresponding to pixel A has a divergent or diffusing effect on the light emitted by pixel A, and the light-guiding structure corresponding to pixel B has a converging effect on the light emitted by pixel B, thereby achieving a light-emitting viewing angle of pixel A that is greater than that of pixel B.
[0056] Some design methods for pixel A 11 and pixel B 12 to achieve different light emitting viewing angles will be introduced below.
[0057] Exemplarily, the A pixel 11 includes sub-pixels of multiple luminous colors, and the B pixel 12 includes sub-pixels of multiple luminous colors. For easy distinction, in the drawings of the present application, the sub-pixels included in the A pixel 11 are marked as R1, G1, and B1, and the sub-pixels included in the B pixel 12 are marked as R2, G2, and B2. Alternatively, in some examples, the sub-pixels included in the B pixel 12 also include sub-pixels marked as R2', G2', and B2'.
[0058] The pixel unit 10 includes a plurality of sub-pixel groups 13 with different luminous colors, and the sub-pixels in the same sub-pixel group 13 are separated by partition walls 20, and the extension direction of the partition walls 20 is the third direction Z, and the first direction X intersects the third direction Z. In this article, the intersection of two directions includes: the two directions are perpendicular or at a certain angle.
[0059] It should be noted that if Figure 2As shown, different sub-pixel groups 13 are also separated, and the “separation wall” in this article refers to the separation wall between sub-pixels of the same luminous color in the same sub-pixel group 13 .
[0060] For example, the sub-pixel group 13 includes a first sub-pixel group 131, a second sub-pixel group 132, and a third sub-pixel group 133. The luminous colors of the first sub-pixel group 131, the second sub-pixel group 132, and the third sub-pixel group 133 are red, green, and blue, respectively. Figure 2 For example, the first sub-pixel group 131 includes sub-pixels R1, R2, and R2', the second sub-pixel group 132 includes sub-pixels G1, G2, and G2', and the third sub-pixel group 133 includes sub-pixels B1, B2, and B2'.
[0061] For example, Figure 3 , Figure 7 and Fig. 9 In the embodiment, the first direction X is parallel to the extending direction of the scanning lines of the display panel. Figure 5 The first direction X intersects with the scan line of the display panel, for example, Figure 5 The first direction X is parallel to the data line of the display panel, wherein the extending directions of the scan line and the data line intersect, and the first direction X is related to the arrangement direction of multiple sub-pixels in the sub-pixel group 13. The extending direction of the scan line can be called the row direction, and the extending direction of the data line can be called the column direction.
[0062] The partition wall 20 is used to separate different sub-pixels in the same sub-pixel group. Fig.10 As shown, the display panel includes a pixel definition layer PDL, the pixel definition layer PDL includes an opening, the light emitting structure of the sub-pixel is arranged corresponding to the opening of the pixel definition layer PDL, and the partition wall 20 may include the pixel definition layer PDL of the display panel.
[0063] The display mode of the display panel includes a first mode and a second mode, and the display viewing angles of the display panel in the first mode and the second mode are different. In this article, it is taken as an example that the display viewing angle of the display panel in the first mode is greater than the display viewing angle of the display panel in the second mode. The first mode may also be referred to as a normal display module, and the second mode may also be referred to as an anti-peeping display mode.
[0064] like Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown in image A in the figure, in the first mode, both pixel A 11 and pixel B 12 emit light, so when pixel A 11 and pixel B 12 emit light at the same time, they can compensate each other to ensure the fineness of the image quality displayed by the display panel in the first mode.
[0065] like Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown in the image B in FIG. 1 , in the second mode, the A pixel does not emit light (the A pixel that does not emit light is hidden in the image B), and the B pixel 12 all emit light. Since the light emitting angle of the B pixel 12 is small, only the B pixel 12 emits light, thereby reducing or even eliminating the light at a large angle, making the large angle picture invisible, thereby achieving the anti-peeping function.
[0066] Further, taking the i-th pixel unit 10i and the j-th pixel unit 10j adjacent to each other in the first direction X as an example, the i-th pixel unit 10i and the j-th pixel unit 10j may be any two adjacent pixel units. In the first mode, the i-th pixel unit 10i and the j-th pixel unit 10j are in a light-emitting state, and the minimum spacing of sub-pixels with the same light-emitting color in the first direction X is a1. In the second mode, the i-th pixel unit 10i and the j-th pixel unit 10j are in a light-emitting state, and the minimum spacing of sub-pixels with the same light-emitting color in the first direction X is b1, and a1=b1.
[0067] It should be noted that the spacing a1 and the spacing b1 refer to the minimum spacing between two sub-pixels in a light-emitting state and emitting the same light color in the first mode and the second mode, respectively. Figure 3 The middle spacing a1 and the spacing b1 represent the spacings between the sub-pixel B2' in the i-th pixel unit 10i and the sub-pixel B2 in the j-th pixel unit 10j in the first mode and the second mode, respectively. Figure 5 The middle spacing a1 and the spacing b1 represent the spacings between the sub-pixel R2' in the i-th pixel unit 10i and the sub-pixel R2 in the j-th pixel unit 10j in the first mode and the second mode, respectively. Figure 7 The middle spacing a1 and the spacing b1 represent the spacings between the sub-pixel B2 in the i-th pixel unit 10i and the sub-pixel B2 in the j-th pixel unit 10j in the first mode and the second mode, respectively. Fig. 9 The middle spacing a1 and the spacing b1 represent the spacings between the sub-pixel B2 ′ in the i-th pixel unit 10 i and the sub-pixel B2 in the j-th pixel unit 10 j in the first mode and the second mode, respectively.
[0068] It should be noted that Figure 3 For example, although Figure 3Only the spacing between the sub-pixel B2' in the i-th pixel unit 10i and the sub-pixel B2 in the j-th pixel unit 10j in the first direction X is marked. In the first direction X, the sub-pixel R2' in the i-th pixel unit 10i and the sub-pixel R2 in the j-th pixel unit 10j have the same minimum spacing in the first mode and the second mode, respectively, and the sub-pixel G2' in the i-th pixel unit 10i and the sub-pixel G2 in the j-th pixel unit 10j have the same minimum spacing in the first mode and the second mode, respectively. Figure 5 , Figure 7 and Fig. 9 The spacings of sub-pixels of other colors in the first direction are similar, and are not described in detail here.
[0069] The display panel provided in the embodiment of the present application includes two display modes, and in the two display modes, in the first direction, the minimum spacing between sub-pixels in a light-emitting state and with the same light-emitting color in two adjacent pixel units is equal, so that when the two display modes are switched, the spacing between light-emitting sub-pixels of the same color in any display mode is avoided from increasing, thereby ensuring the fineness of the display in any display mode and avoiding the occurrence of poor display conditions such as grid patterns.
[0070] In some embodiments, please continue to refer to Figure 3 , Figure 5 , Figure 7 and Fig. 9 In the first mode, the minimum spacing between sub-pixels in the first direction that are in the light-emitting state and whose light-emitting colors are the first color and the second color in the same pixel unit 10 is a2; in the second mode, the minimum spacing between sub-pixels in the first direction that are in the light-emitting state and whose light-emitting colors are the first color and the second color in the same pixel unit is b2; a2=b2.
[0071] It should be noted that the spacing a2 and the spacing b2 refer to the minimum spacing between two sub-pixels in a light-emitting state and emitting different colors in the first mode and the second mode, respectively. Figure 3 The middle spacing a2 and the spacing b2 represent the spacings between the sub-pixel R2' and the sub-pixel B2 in the same pixel unit 10 in the first mode and the second mode, respectively. Figure 5 The middle spacing a2 and the spacing b2 represent the spacings between the sub-pixel R2' and the sub-pixel G2 in the same pixel unit 10 in the first mode and the second mode, respectively. Figure 7 The middle spacing a2 and the spacing b2 represent the spacings between the sub-pixel R2 and the sub-pixel B2 in the same pixel unit 10 in the first mode and the second mode, respectively. Fig. 9 The middle spacing a2 and the spacing b2 represent the spacings between the sub-pixel R2 ′ and the sub-pixel B2 in the same pixel unit 10 in the first mode and the second mode, respectively.
[0072] It should be noted that although Figure 3 Only the distance between the sub-pixel R2' and the sub-pixel B2 in the same pixel unit 10 in the first direction X is marked. In the first direction X, the minimum distances between the sub-pixel G2' and the sub-pixel B2 in the same pixel unit 10 in the first mode and the second mode are equal. Figure 5 to, Figure 7 , Fig. 9 The spacing of the neutron pixels in the first direction is similar, and will not be described in detail here.
[0073] The display panel provided in the embodiment of the present application has the same minimum spacing between sub-pixels in a light-emitting state and with different light-emitting colors in the same pixel unit in the first direction under the two display modes. This avoids an increase in the spacing between light-emitting sub-pixels of different colors in any display mode when switching between the two display modes, thereby further ensuring the fineness of the display in any display mode and better avoiding the occurrence of poor display conditions such as grid patterns.
[0074] Some examples include Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown, the same sub-pixel group 13 includes n1 A sub-pixels 111 and n2 B sub-pixels 121 with the same luminous color, the light emitting viewing angle of the A sub-pixel 111 is greater than the light emitting viewing angle of the B sub-pixel 121, the A pixel 11 includes the A sub-pixel 111, the B pixel 12 includes the B sub-pixel 121, and n1 and n2 are integers greater than 0.
[0075] For example, sub-pixel A 111 includes sub-pixels R1, G1, and B1 in the accompanying drawings, and sub-pixel B 121 includes sub-pixels R2, G2, and B2 in the accompanying drawings, or, in some examples, sub-pixel B 121 also includes pixels of sub-pixels R2', G2', and B2' in the accompanying drawings. Among them, the sub-pixel with the reference mark "R" represents a red sub-pixel, the sub-pixel with the reference mark "G" represents a green sub-pixel, and the sub-pixel with the reference mark "B" represents a blue sub-pixel. The light emitting viewing angles of sub-pixels R2, G2, and B2 and sub-pixels R2', G2', and B2' may be the same, or the light emitting viewing angles of sub-pixels R2, G2, and B2 and sub-pixels R2', G2', and B2' may be within the allowable error range.
[0076] In the same pixel unit 10 , the arrangement rules of the n1 A sub-pixels 111 and the n2 B sub-pixels 121 in different sub-pixel groups 13 are the same, and the overall shapes of the different sub-pixel groups 13 are similar.
[0077] The arrangement rule includes the arrangement order of sub-pixels. The arrangement order of sub-pixels includes: the arrangement order of multiple sub-pixels in the sub-pixel group 13. For example, Figure 2 The arrangement rule of each sub-pixel group 13 is: one A sub-pixel 111 and two B sub-pixels 121 are arranged along the first direction X, and the A sub-pixel 111 is located between the two B sub-pixels 121 .
[0078] The overall shape of the sub-pixel group 13 includes: the overall shape formed by the orthographic projection of the sub-pixel group 13 on the plane where the display panel is located. Figure 2 For example, the orthographic projections of sub-pixel A 111 and sub-pixel B 121 on the plane where the display panel is located are roughly rectangular. Ignoring the intervals between different sub-pixels in the sub-pixel group 13, the overall shape formed by the orthographic projections of the sub-pixel group 13 on the plane where the display panel is located is roughly rectangular.
[0079] In the embodiment of the present application, each sub-pixel group includes sub-pixel A and sub-pixel B, and the arrangement rules of the sub-pixels in different sub-pixel groups are the same, and the overall shapes of different sub-pixel groups are similar, so that when the two modes are displayed, the spacing between the luminous sub-pixels will not change.
[0080] In some embodiments, such as Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown, the same sub-pixel group 13 includes n1 A sub-pixels 111 and n2 B sub-pixels 121 with the same luminous color, the light emitting viewing angle of the A sub-pixel 111 is greater than the light emitting viewing angle of the B sub-pixel 121, the A pixel 11 includes the A sub-pixel 111, the B pixel 12 includes the B sub-pixel 121, n1 and n2 are integers greater than 0, and n1≤n2.
[0081] When n1 is less than n2, that is, there are more B sub-pixels 121 with relatively small light emitting viewing angles. In this way, when the second mode (i.e., the anti-peeping mode) is started, although the A sub-pixel 111 does not emit light and only the B sub-pixel 121 emits light, it is still possible to ensure that more B sub-pixels emit light, thereby ensuring the display effect in the anti-peeping mode (the anti-peeping mode can be understood as a non-large visual mode or a positive viewing angle mode).
[0082] It should be noted that Figures 2 to 9 In the figure, each pattern in the pixel unit can be understood as the orthographic projection shape of the light-emitting structure of the sub-pixel on the plane where the display panel is located. The orthographic projection shape of the light-emitting structure of the sub-pixel on the plane where the display panel is located is, for example, roughly rectangular, triangular, or other shapes. The rectangle or triangle may have chamfers, such as arc chamfers.
[0083] Exemplarily, the sub-pixel includes an anode, a light-emitting layer and a cathode that are stacked, and the light-emitting layer is located between the anode and the cathode. The "light-emitting structure" herein refers to the light-emitting layer.
[0084] For example, within the same pixel unit 10, the ratio of the orthographic projection area of the light emitting structure of the A sub-pixel with different light emitting colors on the plane where the display panel is located is equal to the ratio of the orthographic projection area of the light emitting structure of the B sub-pixel with different light emitting colors on the plane where the display panel is located. Figure 2 For example, within the same sub-pixel group, sub-pixels A of various luminous colors are marked as R1, G1, and B1, respectively, and sub-pixels B of various luminous colors are marked as R2, R2', G2, G2', B2, and B2', respectively, wherein S(R1):S(G1):S(B1)=S(R2+R2'):S(G2+G2'):S(B2+B2'). S(R1) represents the orthographic projection area of the luminous structure of sub-pixel R1 on the plane where the display panel is located, and S(R2+R2') represents the sum of the orthographic projection areas of the luminous structures of sub-pixel R2 and sub-pixel R2' on the plane where the display panel is located. The other expressions have the same meanings and are not described one by one here. This embodiment can make the light emission of sub-pixel A and sub-pixel B more uniform in the first mode.
[0085] In some embodiments, for the same sub-pixel group 13, the total orthographic projection area of the light-emitting structures of n1 A sub-pixels 111 on the plane where the display panel is located is S1, and the total orthographic projection area of the light-emitting structures of n2 B sub-pixels 121 on the plane where the display panel is located is S2, and the difference between S1 and S2 is within 10%.
[0086] For example, S1 and S2 are equal, or the difference between S1 and S2 is 10%, or the difference between S1 and S2 is less than 10%.
[0087] The difference between S1 and S2 is within 10%, that is, the area occupied by the light-emitting structure of n2 B sub-pixels 121 in the same sub-pixel group 13 is not too small. In this way, when the second mode (i.e., the anti-peeping mode) is started, although the A sub-pixel 111 does not emit light and only the B sub-pixel 121 emits light, the display effect in the anti-peeping mode (the anti-peeping mode can be understood as a non-large visual mode or a normal viewing angle mode) can also be guaranteed.
[0088] First, some examples of n2>n1 are described below.
[0089] In some embodiments, such as Figure 2 , Figure 4 , Figure 8As shown, in the same sub-pixel group 13, at least one B sub-pixel 112 is disposed on both sides of the A sub-pixel 111. In the same sub-pixel group 13, at least two B sub-pixels 112 are separated by the A sub-pixel 111, so that different types of sub-pixels of the display panel are distributed relatively evenly as a whole, thereby helping to ensure the display effects in different modes.
[0090] In some embodiments, such as Figure 2 , Figure 4 , Figure 8 As shown, in the same sub-pixel group 13 , at least one B sub-pixel 112 is disposed on both sides of the A sub-pixel 111 . Furthermore, in the same sub-pixel group 13 , n1=1, and n2=2.
[0091] When the area occupied by the sub-pixel group is constant, the larger the number of n1 and n2, the more sub-pixels need to be placed in a certain area, and the smaller the area occupied by a single sub-pixel, which will pose a greater challenge to the manufacturing process.
[0092] In the embodiment of the present application, the total number of sub-pixels in the same sub-pixel group 13 is 3, and two B sub-pixels are located on both sides of the A sub-pixel, which can not only ensure that the different types of sub-pixels of the display panel are distributed relatively evenly as a whole, but also avoid causing greater challenges to the manufacturing process.
[0093] In this article, a plurality of sub-pixels of a sub-pixel group can be regarded as being obtained by dividing a large sub-pixel, and the divided part is used as A sub-pixel and the other part is used as B sub-pixel.
[0094] It should be noted that, in the preparation process of the display panel, when forming multiple sub-pixels of the same sub-pixel, there is no actual "dividing" step. The term "dividing" is used here to describe it more vividly to illustrate the multiple sub-pixels of a sub-pixel group.
[0095] In some embodiments, such as Figure 2 , Figure 4 , Figure 8 As shown, in the same sub-pixel group 13, the light emitting structures of the two B sub-pixels 121 are centrally symmetrical.
[0096] Exemplarily, in the same sub-pixel group 13, the light-emitting structures of two B sub-pixels 121 have the same orthographic projection shapes on the plane where the display panel is located, and, in the same sub-pixel group 13, the light-emitting structures of two B sub-pixels 121 have the same orthographic projection areas on the plane where the display panel is located.
[0097] For example, among two B sub-pixels 121 , the light emitting structure of one B sub-pixel 121 is rotated 180° and then moves to the position where the light emitting structure of the other B sub-pixel 121 is located, and the two light emitting structures may overlap.
[0098] It should be noted that the light emitting structures of the two B sub-pixels 121 are centrally symmetrical, which includes: the light emitting structures of the two B sub-pixels 121 are substantially centrally symmetrical, and a certain error is allowed.
[0099] In the embodiment of the present application, in the same sub-pixel group 13, the light-emitting structures of the two B sub-pixels 121 are centrally symmetrical. Thus, visually, the light emission of the B sub-pixel 121 is relatively uniform, which helps to improve the display visual effect.
[0100] The above examples introduce some examples where n2>n1. The following describes some examples where n1=n2.
[0101] In some embodiments, in the same sub-pixel group, n1=1, n2=1.
[0102] When the area occupied by the sub-pixel group is constant, the larger the number of n1 and n2, the more sub-pixels need to be placed in a certain area, and the smaller the area occupied by a single sub-pixel, which will pose a greater challenge to the manufacturing process.
[0103] In the embodiment of the present application, the total number of sub-pixels in the same sub-pixel group 13 is 2, which can not only ensure that different types of sub-pixels exist in the same sub-pixel group, but also better avoid greater challenges to the manufacturing process.
[0104] In some embodiments, Figure 6 Taking the structure shown as an example, when n1=1 and n2=1, in the same sub-pixel group 13, the light-emitting structure of the A sub-pixel 111 and the light-emitting structure of the B sub-pixel 121 are centrally symmetrical.
[0105] Exemplarily, in the same sub-pixel group 13, the light-emitting structure of sub-pixel A 111 and the light-emitting structure of sub-pixel B 121 have the same orthographic projection shape on the plane where the display panel is located, and, in the same sub-pixel group 13, the light-emitting structure of sub-pixel A 111 and the light-emitting structure of sub-pixel B 121 have the same orthographic projection area on the plane where the display panel is located.
[0106] For example, the light-emitting structure of sub-pixel A 111 and the light-emitting structure of sub-pixel B 121 , wherein the light-emitting structure of sub-pixel A 111 rotates 180° and then moves to the position where the light-emitting structure of sub-pixel B 121 is located, the two light-emitting structures may overlap.
[0107] It should be noted that the light emitting structure of the A sub-pixel 111 and the light emitting structure of the B sub-pixel 121 are centrally symmetrical, which includes: the light emitting structure of the A sub-pixel 111 and the light emitting structure of the B sub-pixel 121 are substantially centrally symmetrical, and a certain error is allowed.
[0108] In the embodiment of the present application, in the same sub-pixel group 13, the light-emitting structure of sub-pixel A 111 and the light-emitting structure of sub-pixel B 121 are centrally symmetrical. In this way, visually, the light emission of sub-pixel A 111 and sub-pixel B 121 is relatively uniform, which helps to improve the display visual effect.
[0109] In some embodiments, Figure 6 As shown, in the case of n1=1 and n2=1, the orthographic projections of the light-emitting structures of the A sub-pixel 111 and the B sub-pixel 121 in the sub-pixel group 13 on the plane where the display panel is located are both triangular.
[0110] It should be noted that the orthographic projection of the sub-pixel light emitting structure on the plane where the display panel is located is a triangle, including: the orthographic projection of the sub-pixel light emitting structure on the plane where the display panel is located is substantially a triangle, and the shape of the orthographic projection of the sub-pixel light emitting structure on the plane where the display panel is located can be considered to be a triangle. The triangle is not a triangle in the absolute sense, the triangle may have chamfers, and the sides of the triangle may be right-angled sides, may be curved sides, or may even be sawtooth or wavy sides.
[0111] In order to more vividly illustrate the shape of the light-emitting structure, for example, the light-emitting structure of the A sub-pixel 111 and the light-emitting structure of the B sub-pixel 121 can be regarded as being obtained by cutting a roughly rectangular or square light-emitting structure into two parts, one of which is used as the light-emitting structure of the A sub-pixel 111, and the other is used as the light-emitting structure of the B sub-pixel 121. It can be divided into two equal parts or unequal parts. The dividing line can be a straight line, an arc, or a line of other shapes. Other examples include Figure 2 , Figure 4 , Figure 8 The shapes of the sub-pixels in the same sub-pixel group shown can also be understood similarly.
[0112] However, it should be noted that when preparing sub-pixel A and sub-pixel B, they are not prepared by dividing in this way.
[0113] In the embodiment of the present application, the orthographic projections of the light-emitting structure of sub-pixel A 111 and the light-emitting structure of sub-pixel B 121 on the plane where the display panel is located are both triangular, so that the orthographic projections of the multiple light-emitting structures in the sub-pixel group 13 on the plane where the display panel is located can form a rectangle or a square as a whole. When the area of the display panel is constant, more sub-pixel groups can be arranged in this way, which can help improve the resolution of the display panel.
[0114] In some embodiments, in the same sub-pixel group 13, no matter how many n1 and n2 are, the orthographic projections of the plurality of light-emitting structures in the sub-pixel group 13 on the plane where the display panel is located can form a rectangle or a square as a whole. Figure 8 For example, it can be understood that a large light-emitting structure is divided into three parts, two of which are used as the light-emitting structure of the B sub-pixel 121, and one is used as the light-emitting structure of the A sub-pixel 111.
[0115] In some embodiments, Figure 6 or Figure 8 As shown, the partition walls 20 of at least two sub-pixel groups of luminous colors extend in different directions. For example, the partition walls 20 of the first sub-pixel group 131 extend in a direction Z1, the partition walls 20 of the second sub-pixel group 132 extend in a direction Z2, and the partition walls 20 of the third sub-pixel group 133 extend in a direction Z3, and the directions Z1, Z2, and Z3 are different from each other. Different sub-pixel groups occupy different areas, or in other words, the overall shapes of different sub-pixel groups differ in size, so the partition walls of different sub-pixel groups extend in different directions, which can better ensure that the spacing between luminous sub-pixels does not change in different display modes.
[0116] Next, some design methods that can achieve different light output angles for different sub-pixels are introduced. It should be noted that the design methods that can achieve different light output angles for different sub-pixels introduced in the embodiments of the present application are merely examples and are not intended to limit the present application. The technical solution of the present application regarding the unchanged spacing of the light-emitting sub-pixels in two modes is universal. That is to say, the technical solution of the present application regarding the unchanged spacing of the light-emitting sub-pixels in two modes can also be applied to other design methods that can achieve different light output angles for different sub-pixels.
[0117] In some embodiments, Figure 2 and Fig.10 For example, pixel A 11 includes sub-pixel A 111, pixel B 12 includes sub-pixel B 121, and the display panel further includes a first light guide structure 31 and / or a second light guide structure 32. The first light guide structure 31 is located at the light-emitting side of sub-pixel A 111, and the second light guide structure 32 is located at the light-emitting side of sub-pixel B 121. The first light guide structure 31 and / or the second light guide structure 32 can adjust the light-emitting viewing angle of the sub-pixels. Specifically, Fig.10 The thick solid line with an arrow represents light. The first light guide structure 31 can diffuse the light emitted by the A sub-pixel 111 and then output it. The second light guide structure 32 can converge the light emitted by the B sub-pixel 121 and then output it, so that the light output viewing angle of the A sub-pixel 111 is greater than the light output viewing angle of the B sub-pixel 121.
[0118] Exemplarily, the display panel includes a substrate 101, and the light-emitting structure of the sub-pixel is located on one side of the substrate 101. For example, the display panel includes an anode layer 102, a light-emitting layer 103, and a cathode layer 104, and the light-emitting structure of the sub-pixel includes an anode, a light-emitting material, and a cathode, the anode of the light-emitting structure is located in the anode layer 102, the light-emitting material of the light-emitting structure is located in the light-emitting layer 103, and the cathode of the light-emitting structure is located in the cathode layer. One anode corresponds to one light-emitting structure, and different anodes are spaced apart by a pixel definition layer PDL.
[0119] The display panel may further include an encapsulation layer 105, which is located on the side of the cathode layer 104 facing away from the substrate 101. The first light guide structure 31 and the second light guide structure 32 are located on the side of the encapsulation layer 105 facing away from the substrate 101, and the first light guide structure 31 overlaps with the orthographic projection of the anode of the A sub-pixel 111 on the substrate 101, and the second light guide structure 32 overlaps with the orthographic projection of the anode of the B sub-pixel 121 on the substrate 101.
[0120] like Fig.10 As shown, the display panel may further include a cover plate 106 and a polarizer 107. For example, the cover plate 106 may be a glass cover plate or a cover plate made of other materials.
[0121] In the embodiment of the present application, a first light-guiding structure capable of diffusing light is provided corresponding to sub-pixel A, and a second light-guiding structure capable of converging light is provided corresponding to sub-pixel B, so that the light-emitting viewing angle of sub-pixel A is greater than that of sub-pixel B.
[0122] For some embodiments, please continue to refer to Fig.10 The first light guide structure 31 includes a first lens layer 311 and a first filling layer 312 which are stacked and have different refractive indices, and the contact surface between the first lens layer 311 and the first filling layer 312 is a first curved surface f1. The second light guide structure 32 includes a second lens layer 321 and a second filling layer 322 which are stacked and have different refractive indices, and the contact surface between the second lens layer 321 and the second filling layer 322 is a second curved surface f2.
[0123] It can be understood that the surface of the first lens layer 311 facing the first filling layer 312 is a curved surface, the surface of the first filling layer 312 facing the first lens layer 311 is a curved surface, and the opposite surfaces of the first lens layer 311 and the first filling layer 312 match each other. The surface of the second lens layer 321 facing the second filling layer 322 is a curved surface, the surface of the second filling layer 322 facing the second lens layer 321 is a curved surface, and the opposite surfaces of the second lens layer 321 and the second filling layer 322 match each other.
[0124] The curvature of the first curved surface f1 and the second curved surface f2 may be the same or different, which is not limited in the present application.
[0125] Exemplarily, the upper and lower surfaces of the first light guide structure 31 are both planes, and the upper and lower surfaces of the second light guide structure 32 are both planes. That is, the surface of the first lens layer 311 facing away from the first filling layer 312 is a plane, and the surface of the first filling layer 312 facing away from the first lens layer 311 is a plane. The surface of the second lens layer 321 facing away from the second filling layer 322 is a plane, and the surface of the second filling layer 322 facing away from the second lens layer 321 is a plane.
[0126] In an embodiment of the present application, the light-guiding structure includes a stacked lens layer and a filling layer with different refractive indices, and the contact surface between the lens layer and the filling layer is a curved surface, so that the propagation direction of the light at the contact surface will change, thereby facilitating the realization of a light-guiding structure with a focusing or diffusing light effect.
[0127] Some specific structures of the first light guide structure are first introduced below.
[0128] In some embodiments, Fig.10 As shown, the first curved surface f1 is a curved surface protruding toward the A sub-pixel 111 , the first filling layer 312 is located between the A sub-pixel 111 and the first lens layer 311 , and the refractive index of the first filling layer 312 is greater than the refractive index of the first lens layer 311 .
[0129] Since the first filling layer 312 is closer to the A sub-pixel 111 and the refractive index of the first filling layer 312 is greater than the refractive index of the first lens layer 311, the light emitted from the A sub-pixel 111 reaches the first curved surface f1 through the first filling layer 312 and is refracted on the first curved surface f1 and emitted outward at a larger angle, thereby achieving diffusion of the light and making the light output viewing angle of the A sub-pixel 111 relatively larger.
[0130] In other embodiments, Fig.11 As shown, the first curved surface f1 is a curved surface convex toward the back of the A sub-pixel 111 , the first lens layer 311 is located between the A sub-pixel 111 and the first filling layer 312 , and the refractive index of the first filling layer 312 is less than the refractive index of the first lens layer 311 .
[0131] Since the first lens layer 311 is closer to the A sub-pixel 111 and the refractive index of the first lens layer 311 is greater than the refractive index of the first filling layer 312, the light emitted from the A sub-pixel 111 reaches the first curved surface f1 through the first lens layer 311 and is refracted on the first curved surface f1 and emitted outward at a larger angle, thereby achieving diffusion of the light, so that the light output viewing angle of the A sub-pixel 111 is relatively larger.
[0132] Some specific structures of the second light guiding structure are introduced below.
[0133] In some embodiments, Fig.10 or Fig.11As shown, the second curved surface f2 is a curved surface convex toward the back of the second sub-pixel 121 , the second lens layer 321 is located between the second sub-pixel 121 and the second filling layer 322 , and the refractive index of the second filling layer 322 is greater than the refractive index of the second lens layer 321 .
[0134] Since the second lens layer 321 is closer to the B sub-pixel 121 and the refractive index of the second lens layer 321 is smaller than the refractive index of the second filling layer 322, the light emitted from the B sub-pixel 121 reaches the second curved surface f2 through the second lens layer 321, and is refracted at the second curved surface f2 and emitted outward at a smaller angle, thereby achieving the convergence of the light and making the light output viewing angle of the B sub-pixel 121 relatively smaller.
[0135] In other embodiments, Fig.12 As shown, the second curved surface f2 is a curved surface convex toward the second sub-pixel 121 , the second filling layer 322 is located between the second sub-pixel 121 and the second lens layer 321 , and the refractive index of the second filling layer 322 is less than the refractive index of the second lens layer 321 .
[0136] Since the second filling layer 322 is closer to the B sub-pixel 121 and the refractive index of the second filling layer 322 is smaller than the refractive index of the second filling layer 322, the light emitted from the B sub-pixel 121 reaches the second curved surface f2 through the second filling layer 322, and is refracted at the second curved surface f2 and emitted outward at a smaller angle, thereby achieving the convergence of the light and making the light output viewing angle of the B sub-pixel 121 relatively smaller.
[0137] Two design modes of the first light guide structure and two design modes of the second light guide structure are introduced above. Any design mode of the first light guide structure and any design mode of the second light guide structure may be selected.
[0138] As an example, Fig.10 As shown, the first light guide structure 31 is designed in the following manner: the first curved surface f1 is a curved surface convex toward the A sub-pixel 111, the first filling layer 312 is located between the A sub-pixel 111 and the first lens layer 311, and the refractive index of the first filling layer 312 is greater than the refractive index of the first lens layer 311. Moreover, the second light guide structure 32 is designed in the following manner: the second curved surface f2 is a curved surface convex away from the B sub-pixel 121, the second lens layer 321 is located between the B sub-pixel 121 and the second filling layer 322, and the refractive index of the second filling layer 322 is greater than the refractive index of the second lens layer 321.
[0139] For example, Fig.10 In the embodiment, the refractive index of the first lens layer 311 is equal to the refractive index of the second lens layer 321 , and the refractive index of the second filling layer 322 is equal to the refractive index of the first filling layer 312 .
[0140] As an example, Fig.11 As shown, the first light guide structure 31 is designed in the following manner: the first curved surface f1 is a curved surface convexed away from the A sub-pixel 111, the first lens layer 311 is located between the A sub-pixel 111 and the first filling layer 312, and the refractive index of the first filling layer 312 is less than the refractive index of the first lens layer 311. Moreover, the second light guide structure 32 is designed in the following manner: the second curved surface f2 is a curved surface convexed away from the B sub-pixel 121, the second lens layer 321 is located between the B sub-pixel 121 and the second filling layer 322, and the refractive index of the second filling layer 322 is greater than the refractive index of the second lens layer 321.
[0141] For example, Fig.11 In the embodiment, the refractive index of the first lens layer 311 is equal to the refractive index of the second lens layer 321 , and the refractive index of the second filling layer 322 is greater than the refractive index of the first filling layer 312 .
[0142] Of course, in other examples, it can also be designed as follows: only the A sub-pixel is provided with the first light-guiding structure with the light-diffusing function, while the B sub-pixel is not provided with the second light-guiding structure with the light-converging function; or, it can be designed as follows: only the B sub-pixel is provided with the second light-guiding structure with the light-converging function, while the A sub-pixel is not provided with the first light-guiding structure with the light-diffusing function.
[0143] Some examples include Fig.10 As shown, the first light guide structure 31 and the second light guide structure 32 are separated by a first light shielding structure 41. Exemplarily, the material of the first light shielding structure 41 includes a black matrix (BM). It is understandable that the light shielding structure can prevent light from passing through.
[0144] The first light shading structure 41 includes a first side surface c1 and a second side surface c2, the first side surface c1 faces the first light guiding structure 31, and the second side surface c2 faces the second light guiding structure 32, an angle θ1 between the first side surface c1 and the plane where the display panel is located is an obtuse angle, and an angle θ2 between the second side surface c2 and the plane where the display panel is located is less than or equal to 90°.
[0145] For example, the angle θ1 is 135° or other values greater than 90° and less than 180°. The angle θ2 is 90° or other values less than 90° and greater than 0°. The larger the angle θ1 is, the greater the light output angle of the A sub-pixel 111 can be, and the smaller the angle θ2 is, the smaller the light output angle of the B sub-pixel 121 can be.
[0146] Exemplarily, the first side surface c1 and the second side surface c2 are both inclined planes, and in the direction toward the light emitting surface close to the display panel, the opening area enclosed by the first side surface c1 becomes larger and larger, while the opening area enclosed by the second side surface c2 becomes smaller and smaller.
[0147] In some embodiments, Fig.13 As shown, the first light guiding structure 31 includes a plurality of first light guiding units 301 arranged at intervals, and different first light guiding units 301 are separated by a second light shading structure 42; and / or, the second light guiding structure 32 includes a plurality of second light guiding units 302 arranged at intervals, and different second light guiding units 302 are separated by a second light shading structure 42.
[0148] Exemplarily, the second light shielding structure 42 may also include BM.
[0149] Exemplarily, the structure of each first light guide unit 301 is the same as the specific structure of the first light guide structure 31 described in the above example. The structure of each second light guide unit 302 is the same as the specific structure of the second light guide structure 32 described in the above example.
[0150] The plurality of first light guide units 301 corresponding to the same A sub-pixel may be arranged in an array. The plurality of second light guide units 302 corresponding to the same B sub-pixel may be arranged in an array.
[0151] The light guiding structures corresponding to the multiple sub-pixels of the same sub-pixel group 13 are separated by the first shading structure 41. The light guiding structures of different sub-pixel groups 13 can also be separated by the first shading structure 41. The first shading structure 41 and the second shading structure 42 are interconnected to form a grid type as a whole.
[0152] In the embodiment of the present application, the first light guide structure is divided into a plurality of small first light guide units, which can better diffuse the light; the second light guide structure is divided into a plurality of small second light guide units, which can better converge the light.
[0153] In some embodiments, Fig.14 As shown, the display panel also includes a pixel driving circuit 50, a first end of the pixel driving circuit 50 is electrically connected to the first power supply end PVDD, a second end of the pixel driving circuit 50 is electrically connected to pixel A 11 and pixel B 12, one of pixel A 11 and pixel B 12 is directly electrically connected to the output end of the pixel driving circuit 50, and the other is electrically connected to the output end of the pixel driving circuit 50 through a selection module 60.
[0154] Fig.14 In the figure, the B pixel 12 is directly electrically connected to the output end of the pixel driving circuit 50, and the A pixel 11 is electrically connected to the output end of the pixel driving circuit 50 through the gating module 60. It is understandable that it can also be designed as follows: the A pixel 11 is directly electrically connected to the output end of the pixel driving circuit 50, and the B pixel 12 is electrically connected to the output end of the pixel driving circuit 50 through the gating module 60.
[0155] In the embodiment of the present application, pixel A and pixel B share a pixel driving circuit, which can reduce the number of pixel driving circuits and improve the resolution of the display panel.
[0156] Exemplarily, pixel A includes sub-pixels A of multiple luminous colors, and pixel B includes sub-pixels B of multiple luminous colors. Specifically, in the same sub-pixel group, sub-pixels A and B of the same luminous color share a pixel driving circuit, and sub-pixels of different luminous colors are connected to different pixel driving circuits. For example, in the same sub-pixel group, red sub-pixels R1, R2, and R2' share a pixel driving circuit, green sub-pixels G1, G2, and G2' share another pixel driving circuit, and blue sub-pixels B1, B2, and B2' share another pixel driving circuit. That is, corresponding to one pixel unit, there are three sub-pixel groups with different luminous colors, and three pixel driving circuits are designed. For n pixel units, 3*n pixel driving circuits can be designed.
[0157] For example, Fig.14 Taking the example that the pixel driving circuit 50 includes 7 transistors and 1 storage capacitor, this is certainly not used to limit the present application. In other examples, the pixel driving circuit 50 may also be a circuit with other structures.
[0158] In some examples, in the first mode, the gating module 60 is turned on, and the driving current generated by the pixel driving circuit 50 drives both pixel A and pixel B to emit light. In the second mode, the gating module 60 is turned off. The driving current generated by the pixel driving circuit 50 is only transmitted to the pixels directly electrically connected to it. For example, in the second mode, only pixel B needs to emit light, so the pixel driving circuit 50 is directly electrically connected to pixel B, so that the pixel driving circuit 50 only drives pixel B to emit light.
[0159] For example, Fig.15 , Fig.16 As shown, Fig.15 Specifically shows a timing diagram of the pixel driving circuit in the first mode, Fig.16 A timing diagram of the pixel driving circuit in the second mode is specifically shown. The working process of the pixel circuit may include a pre-stage p1 and a light-emitting stage p2. In the pre-stage p1, the scan signals Scan-1 and Scan-2 are respectively at valid levels. When the scan signal Scan-1 is at a valid level, the reset signal Vref resets the gate of the driving transistor M3 and the anode of the light-emitting structure. When the scan signal Scan-2 is at a valid level, the data signal Vdata is written, and the transistor M4 compensates for the threshold voltage of the driving transistor M3. In the light-emitting stage p2, the light-emitting control signal Emit is at a low level, and the pixel driving circuit generates a driving current to drive the corresponding pixel to emit light.
[0160] It should be noted that Fig.15 and Fig.16 In the figure, the effective level is represented as a low level.
[0161] like Fig.15 As shown, in the first mode, the scan signal Scan-3 is at a high level in the pre-stage p1, and the gating module 60 is disconnected; the scan signal Scan-3 is at a low level in the light-emitting stage p2, and the gating module 60 is turned on.
[0162] like Fig.16 As shown, in the second mode, the scan signal Scan-3 is at a high level (Vgh) in both the pre-stage p1 and the light-emitting stage p2, and the gating module 60 remains disconnected.
[0163] In some embodiments, such as Fig.17 As shown, the pixel driving circuit 50 is electrically connected to the plurality of B pixels 12 through a plurality of connection lines. The plurality of B pixels 12 here refer to a plurality of B sub-pixels 121 of the same luminous color.
[0164] For example, the sub-pixel 121 includes sub-pixels R2 and R2', sub-pixel R2 is electrically connected to the pixel driving circuit 50 via the first connection line 71, and sub-pixel R2' is electrically connected to the pixel driving circuit 50 via the second connection line 72. The anodes of the sub-pixels R2 and R2' are separated from each other.
[0165] It should be noted that the transistor in the embodiment of the present application can be an N-type transistor or a P-type transistor. For an N-type transistor, the on-level is a high level and the off-level is a low level. That is, when the gate potential of the N-type transistor is a high level, the first pole and the second pole are connected, and when the gate potential of the N-type transistor is a low level, the first pole and the second pole are disconnected. For a P-type transistor, the on-level is a low level and the off-level is a high level. That is, when the gate potential of the P-type transistor is a low level, the first pole and the second pole are connected, and when the gate potential of the P-type transistor is a high level, the first pole and the second pole are disconnected. In a specific implementation, the gate of each of the above-mentioned transistors serves as its control electrode, and, according to the signal of the gate of each transistor and its type, its first electrode can be used as the source and the second electrode as the drain, or its first electrode can be used as the drain and the second electrode as the source, without making any distinction here. In addition, the on-level and off-level in the embodiments of the present application are general terms, the on-level refers to any level that can turn on the transistor, and the off-level refers to any level that can turn off / shut down the transistor.
