[0002] With the increase in the market capacity of liquid crystal head-up display (LCD HUD) products and the continuous improvement in customer requirements for HUD product specifications, especially the increase in demand for in-vehicle HUD products from high-end customers, the special-shaped design of in-vehicle HUD products has become the current trend of in-vehicle HUD products.

[0003] The so-called special-shaped design of the vehicle head-up display product means that the shape of the display area is not a regular rectangle, such as Figure 1 , at least part of the boundary line of the display area is a curve. At the position of the curve, the display screen is prone to yellowing. Utility Model Content

[0004] In view of this, an object of the present application is to provide a display panel and a display device.

[0005] Based on the above-mentioned purpose, the first aspect of the present application provides a display panel, including a display area, the display area including a grayscale transition area located at the boundary and a full grayscale area except the grayscale transition area; the display panel includes a plurality of first sub-pixels located in the full grayscale area and a plurality of second sub-pixels located in the grayscale transition area, the second sub-pixels including a first part that emits light and a second part that does not emit light; the full grayscale area and the grayscale transition area are respectively provided with a first spacer and a second spacer, and the distribution density of the first spacer is greater than the distribution density of the second spacer.

[0006] Optionally, the first spacer includes a first auxiliary spacer, and the second spacer includes a second auxiliary spacer; the distribution density of the first auxiliary spacer is greater than the distribution density of the second auxiliary spacer.

[0007] Optionally, the grayscale transition area includes a first transition sub-area and a second transition sub-area, the display grayscale of the second sub-pixel in the first transition sub-area is greater than or equal to a preset threshold, and the display grayscale of the second sub-pixel in the second transition sub-area is less than the preset threshold; the second auxiliary spacer is only arranged in the first transition sub-area.

[0008] Optionally, in the second sub-pixel, the first portion is disposed in the middle, and at least two second portions are disposed and are symmetrically disposed with respect to the first portion.

[0009] Optionally, the second sub-pixel is rectangular.

[0010] Optionally, the second spacer includes a second auxiliary spacer; the second auxiliary spacer is arranged close to a vertex corner of the second sub-pixel.

[0011] Optionally, the second auxiliary spacer is a columnar structure.

[0012] Optionally, the display panel includes a color film substrate, the color film substrate includes a color film base and a color filter layer arranged on one side of the color film base, and the second spacer is arranged on a side of the color filter layer away from the color film base.

[0013] Optionally, the color filter layer includes multiple color filters and a black matrix, the black matrix includes a first shading area and a second shading area; the black matrix of the first shading area is arranged between adjacent color filters; along the thickness direction of the display panel, the orthographic projection of the second shading area on the color filter substrate coincides with the orthographic projection of the second part on the color filter substrate.

[0014] Optionally, along the thickness direction of the display panel, an orthographic projection of the second spacer on the color filter substrate at least partially overlaps with an orthographic projection of the black matrix of the first light-shielding area on the color filter substrate.

[0015] Optionally, a protective layer is further provided between the color filter layer and the second spacer.

[0016] Based on the same inventive concept, the second aspect of the present application further provides a display device, comprising the display panel as described in the first aspect.

[0017] From the above, it can be seen that in the display panel and display device provided by the present application, the second sub-pixel in the grayscale transition area is used to form a curved boundary of the display area. Since the distribution density of the second spacer is less than that of the first spacer, the average support force provided by the second spacer to the upper structural layer in the grayscale transition area is smaller, which makes the upper structural layer more likely to sag, thereby reducing the box thickness of the grayscale transition area of ​​the display panel to a certain extent, helping to narrow the box thickness difference between the grayscale transition area and the full grayscale area, thereby improving the problem of yellowing of the display panel display screen.

[0040] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0041] It should be noted that the relative arrangement of the components, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise.

[0042] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] For special-shaped head-up display products, Figure 1 The display panel shown in FIG. 1 is used as an example for explanation.

[0046] The display panel includes a display area 1, and the display area 1 includes a grayscale transition area 101 and a full grayscale area 102 except the grayscale transition area 101. The display boundaries of the full grayscale area 102 are all straight line boundaries, while the grayscale transition area 101 includes an arc-shaped display boundary ( Figure 1 The upper boundary of the grayscale transition region 101 in the direction shown).

[0047] Specifically, Figure 2 In the full grayscale area 102, a plurality of first sub-pixels 2 are arranged in an array. For the first sub-pixels 2 at the boundary of the full grayscale area 102, normal full-area light emission can form a straight boundary.

[0048] In the grayscale transition region 101, a plurality of second sub-pixels 3 are arranged in the array. However, for the second sub-pixels 3 at the boundary of the grayscale transition region 101, a non-luminous second portion 302 is provided so that the luminous first portion 301 can form an arc-shaped display boundary ( Figure 2 (shown by the arc-shaped dotted line in the middle).

[0049] The applicant has found that it is precisely because of the structural difference between the first sub-pixel 2 and the second sub-pixel 3 that the thickness of the color filter substrate 6 in the display panel is not consistent. The thickness of the color filter substrate 6 in the grayscale transition area 101 is greater than the thickness of the color filter substrate 6 in the full grayscale area 102. Figure 3 , exemplarily, the thickness difference between the two may be 0.55 μm.

[0050] In the existing display panel, the existing spacers 8 (for example, columnar spacers PS) are evenly arranged on the color film substrate 6 according to a pre-designed distribution density. Then, after the color film substrate 6 and the array substrate 9 are aligned, under the supporting force of the existing spacers 8, the box thickness (Gap) of the grayscale transition area 101 will be higher than the box thickness of the full grayscale area 102. The greater the height difference between the two, the more serious the yellowing problem of the grayscale transition area 101 will be when the existing display panel displays the picture.

[0051] For example, when the existing spacers 8 are evenly arranged, the cell thickness of the grayscale transition region 101 and the cell thickness of the full grayscale region 102 are as follows: Figure 4 As shown, the difference between the two is Δ=0.178 μm.

[0052] In other words, reducing the height difference between the grayscale transition area 101 and the full grayscale area 102 can improve the yellowing problem of the existing display panel.

[0053] In view of this, if Figure 5As shown, an embodiment of the present application provides a display panel, including a display area 1, the display area 1 includes a grayscale transition area 101 located at the boundary and a full grayscale area 102 except the grayscale transition area 101; the display panel includes a plurality of first sub-pixels 2 located in the full grayscale area 102 and a plurality of second sub-pixels 3 located in the grayscale transition area 101, the second sub-pixels 3 include a first luminous part 301 and a second non-luminous part 302; the full grayscale area 102 and the grayscale transition area 101 are respectively provided with a first spacer 4 and a second spacer 5, and the distribution density of the first spacer 4 is greater than the distribution density of the second spacer 5.

[0054] For example, the distribution density may be the number of spacers in an area formed by a unit number of sub-pixels, or the number of spacers in a unit area.

[0055] Exemplarily, the height of the first spacer 4 and the height of the second spacer 5 may be the same or different, which is not limited here.

[0056] by Figure 6 The display panel shown is taken as an example for explanation.

[0057] Taking the full grayscale area 102 as an example, the first spacer 4 supports the color filter substrate 6. It can be understood that the area where the color filter substrate 6 contacts the first spacer 4 is subject to greater supporting force, and the box thickness here is also higher; and the farther the suspended area is from the first spacer 4, the smaller the supporting force on the color filter substrate 6 is, and the color filter substrate 6 in this area will sag, so the box thickness will be relatively low.

[0058] In the display panel of this embodiment, the distribution density of the first spacers 4 is relatively high, and the total contact area between the color filter substrate 6 and the first spacers 4 in the full grayscale region 102 accounts for a relatively large proportion of the total area of ​​the full grayscale region 102, so the average box thickness of the full grayscale region 102 will be relatively high.

[0059] Combining the above contents, it can be known that the thickness of the color filter substrate 6 in the grayscale transition region 101 is relatively thick. Therefore, in the display panel of this embodiment, the distribution density of the second spacers 5 is less than the distribution density of the first spacers 4. Accordingly, the total contact area of ​​the color filter substrate 6 in the grayscale transition region 101 and the second spacers 5 accounts for a smaller proportion of the total area of ​​the grayscale transition region 101. Figure 6 , which makes the color filter substrate 6 in the grayscale transition area 101 have more sagging areas with lower cell thickness (e.g. Figure 6 This helps to reduce the average cell thickness of the grayscale transition region 101, reduce the cell thickness difference between the grayscale transition region 101 and the full grayscale region 102, and thus improve the yellowing problem of the display panel.

[0060] In the display panel provided in the present embodiment, the second sub-pixel 3 of the grayscale transition region 101 is used to form a curved boundary of the display area 1. Since the distribution density of the second spacer 5 is less than the distribution density of the first spacer 4, the average supporting force provided by the second spacer 5 to the upper structural layer in the grayscale transition region 101 is smaller, which makes the upper structural layer more likely to sag, thereby reducing the box thickness of the grayscale transition region 101 of the display panel to a certain extent, helping to reduce the box thickness difference between the grayscale transition region 101 and the full grayscale region 102, thereby improving the problem of yellowing of the display panel display screen.

[0061] The display panel of this embodiment is particularly suitable for medium-to-large-sized and special-shaped vehicle head-up display products.

[0062] like Figure 7 As shown, in some embodiments, the first spacer 4 includes a first auxiliary spacer 401 , and the second spacer 5 includes a second auxiliary spacer 501 ; the distribution density of the first auxiliary spacer 401 is greater than the distribution density of the second auxiliary spacer 501 .

[0063] Exemplarily, the first spacer 4 may also include a first main spacer and / or the second spacer 5 may also include a second main spacer. The first main spacer and the first auxiliary spacer 401 together support the structural layer (e.g., color filter substrate 6) above the first spacer 4 in the full grayscale region 102, and the second main spacer and the second auxiliary spacer 501 together support the structural layer (e.g., color filter substrate 6) above the second spacer 5 in the grayscale transition region 101.

[0064] Exemplarily, the height of the first main spacer may be greater than the height of the first auxiliary spacer 401 , or the heights of the two spacers may be equal.

[0065] Exemplarily, the height of the second main spacer may be greater than the height of the second auxiliary spacer 501 , or the heights of the two spacers may be equal.

[0066] Exemplarily, the first main spacer and / or the second main spacer may be a columnar main spacer (Main PS).

[0067] Exemplarily, the distribution density of the second main spacers may be the same as the distribution density of the first main spacers.

[0068] Exemplarily, the first sub-spacer 401 and / or the second sub-spacer 501 may be a columnar sub-spacer (SubPS).

[0069] Taking the second spacer 5 as an example, in the display panel, the second auxiliary spacer 501 plays the role of auxiliary support, and the structural layer above the second spacer 5 is mainly supported by the second main spacer in the second spacer 5. In order to achieve that the distribution density of the second spacer 5 is less than the distribution density of the first spacer 4, in this embodiment, the distribution density of the second auxiliary spacer 501 in the second spacer 5 can be preferentially reduced to ensure that the remaining second spacer 5 can still provide reliable support for the structural layer above it, and prevent the problem of poor display due to the structural layer above the second spacer 5 being subjected to too little support force, so that the box thickness of the grayscale transition area 101 is less than the box thickness of the full grayscale area 102.

[0070] like Figure 8 As shown, in some embodiments, the grayscale transition area 101 includes a first transition sub-area 1011 and a second transition sub-area 1012, the display grayscale of the second sub-pixel 3 in the first transition sub-area 1011 is greater than or equal to a preset threshold, and the display grayscale of the second sub-pixel 3 in the second transition sub-area 1012 is less than the preset threshold; the second auxiliary spacer 501 is only arranged in the first transition sub-area 1011.

[0071] by Fig. 9 The structure of the second sub-pixel 3 in the grayscale transition region 101 is taken as an example for description.

[0072] In order to form the curved boundary of the display area 1, the second sub-pixel 3 at different positions in the grayscale transition area 101 has different display grayscales. Taking the display grayscale of the first sub-pixel 2 as 267 as an example, the display grayscale of the second sub-pixel 3 can be 5, 42, 65, 81, 94, 105, 114, 123, 131, 139, 246, 250 and 254, etc.

[0073] Fig. 9 FIG. 1 is a schematic diagram showing the arrangement of the existing spacers 8 in the grayscale transition region 101 in the existing display panel. It can be seen that even if the display grayscale of the second sub-pixel 3 is relatively small, the existing spacers 8 (such as Fig. 9 shown in the rectangular box).

[0074] The smaller the second sub-pixel 3 displays, the smaller the area occupied by the first part 301 in the second sub-pixel 3, and correspondingly, the larger the area occupied by the second part 302 in the second sub-pixel 3. In combination with the foregoing, it can be seen that the reason why the box thickness of the grayscale transition area 101 and the box thickness of the full grayscale area 102 are greatly different is that the thickness of the color filter substrate 6 in the grayscale transition area 101 is relatively large. The applicant has found that for the second sub-pixel 3, the larger the area occupied by the second part 302, the greater the average thickness of the second sub-pixel 3. In other words, in this embodiment, the thickness difference between the color filter substrate 6 in the grayscale transition area 101 and the color filter substrate 6 in the full grayscale area 102 is mainly reflected in the second transition sub-region 1012.

[0075] Therefore, in order to achieve that the distribution density of the second spacers 5 is lower than that of the first spacers 4, in this embodiment, the second auxiliary spacers 501 in the second transition sub-region 1012 may be removed preferentially. Figure 8 , which can have a more obvious effect on reducing the box thickness in the grayscale transition area 101.

[0076] Fig.10 FIG. 1 is a schematic diagram showing the arrangement of the second auxiliary spacer 501 in the grayscale transition region 101 of the display panel of this embodiment. It can be seen that for the second sub-pixel 3 whose display grayscale is lower than the preset threshold (for example, the preset threshold may be 139, 246, 250 or 254), the second auxiliary spacer 501 is no longer arranged around it (for example, the second sub-pixel 3 is not arranged around the second sub-pixel 3). Fig.10 As shown in the rectangular box, the second auxiliary spacer 501 is no longer provided in the second transition sub-region 1012. The second auxiliary spacer 501 is provided only in the first transition sub-region 1011.

[0077] Fig.11 The cell thickness of the grayscale transition region 101 and the cell thickness of the full grayscale region 102 of the display panel in this embodiment are shown, and the difference between the two is Δ′=0.06 μm.

[0078] At the same time, the second auxiliary spacer 501 in the first transition sub-region 1011 has little effect on the cell thickness of the grayscale transition region 101 , and is retained to play an auxiliary supporting role for the structural layer above the second spacer 5 .

[0079] like Figure 5 As shown, in some embodiments, in the second sub-pixel 3 , the first portion 301 is disposed in the middle, and at least two second portions 302 are disposed and are symmetrically disposed relative to the first portion 301 .

[0080] For example, Figure 1 As an example, the grayscale transition region 101 shown in the figure can form an arc-shaped boundary of the display area 1. When the arc-shaped boundary is along the first direction (eg Figure 1 When the second portion 302 is bent along the first direction (eg, Figure 5 (in the X direction) are arranged on opposite sides of the first portion 301.

[0081] The first portion 301 is disposed at the middle position of the second sub-pixel 3 , so that the light output of the second sub-pixel 3 can be more uniform.

[0082] like Figure 5 As shown, in some embodiments, the second sub-pixel 3 is rectangular.

[0083] Exemplarily, the shape of the first sub-pixel 2 is the same as the shape of the second sub-pixel 3 .

[0084] In a unit area, compared with other shapes, a larger number of rectangular sub-pixels can be arranged in an array. Setting the second sub-pixel 3 in a rectangular shape helps to make the display panel have a higher resolution.

[0085] like Figure 7 As shown, in some embodiments, the second auxiliary spacer 501 is disposed close to the top corner of the second sub-pixel 3 .

[0086] The second auxiliary spacer 501 is disposed close to the top corner of the rectangular second sub-pixel 3 , which can effectively reduce the shielding of the second auxiliary spacer 501 on the light output of the second sub-pixel 3 , and helps to improve the display effect of the display panel.

[0087] like Fig.12 As shown, in some embodiments, the display panel includes a color filter substrate 6, the color filter substrate 6 includes a color filter substrate 601 and a color filter layer 602 arranged on one side of the color filter substrate 601, and the second spacer 5 is arranged on the side of the color filter layer 602 away from the color filter substrate 601.

[0088] The display panel further includes an array substrate 9 arranged in a box with the color filter substrate 6 , and a liquid crystal layer 7 arranged between the color filter substrate 6 and the array substrate 9 .

[0089] Exemplarily, the color film substrate 601 may be made of a transparent material, such as transparent glass or transparent resin, etc., which is not limited here.

[0090] When the color filter substrate 6 and the array substrate 9 are assembled, the second spacer 5 is located between the two, and at least one end of the second spacer 5 abuts against the color filter substrate 6 and the other end abuts against the array substrate 9, so that the second spacer 5 can support the color filter substrate 6.

[0091] like Fig.12 and Fig.13As shown, in some embodiments, the color filter layer 602 includes a plurality of color filters 6022 and a black matrix 6021, the black matrix 6021 includes a first light shielding area 60211 and a second light shielding area 60212; the black matrix 6021 of the first light shielding area 60211 is disposed between adjacent color filters 6022; along the thickness direction of the display panel (such as Fig.13 In the Z direction), the orthographic projection of the second light-shielding area 60212 on the color filter substrate 601 coincides with the orthographic projection of the second portion 302 on the color filter substrate 601.

[0092] Exemplarily, the plurality of color filters 6022 may include a red filter R, a green filter G, and a blue filter B. With the help of the red filter R, the green filter G, and the blue filter B, the color passing through the liquid crystal layer 7 can be changed into corresponding red, green, and blue, so as to form the color required for the display screen.

[0093] Exemplarily, the red filter R, the green filter G and the blue filter B are arranged in an array according to a preset order.

[0094] The first light shielding region 60211 of the black matrix 6021 is used to define a plurality of sub-pixel regions arranged in an array in the color filter substrate 6 , and a plurality of color filters 6022 can be arranged in the plurality of sub-pixel regions in a one-to-one correspondence.

[0095] The second light shielding area 60212 of the black matrix 6021 is disposed in the second sub-pixel 3 to shield light from a portion of the second sub-pixel 3 , thereby forming a second non-luminous portion 302 in the second sub-pixel 3 .

[0096] In combination with the foregoing, it can be seen that for the first sub-pixel 2 and the first part 301 of the second sub-pixel 3, the first shading area 60211 of the black matrix 6021 is arranged between two adjacent color filters 6022, and for the second part 302 of the second sub-pixel 3, the color filter 6022 and the second shading area 60212 of the black matrix 6021 are stacked, so the second part 302 of the second sub-pixel 3 is thicker, which is also one of the reasons why the color film substrate 6 in the grayscale transition area 101 is thicker.

[0097] like Fig.12 As shown, in some embodiments, along the thickness direction of the display panel (eg Fig.12 In the Z direction), the orthographic projection of the second spacer 5 on the color filter substrate 601 at least partially overlaps with the orthographic projection of the black matrix 6021 of the first light shielding area 60211 on the color filter substrate 601.

[0098] The second sub-pixel 3 emits light through the color filter 6022 , the portion of the black matrix 6021 between the two color filters 6022 for setting the first shading area 60211 does not emit light, and the portion where the second spacer 5 overlaps with the first shading area 60211 will not block the light output of the second sub-pixel 3 .

[0099] like Fig.12 and Fig.13 As shown, in some embodiments, a protective layer 603 (OC) is further disposed between the color filter layer 602 and the second spacer 5 .

[0100] Exemplarily, the protection layer 603 is a structural layer made of a transparent material.

[0101] On one hand, the protective layer 603 can protect the color filter 6022 ; on the other hand, the protective layer 603 can also form a flat surface on the side of the color filter layer 602 away from the color filter substrate 601 , facilitating the subsequent formation of the first spacer 4 and the second spacer 5 .
