Description

Technical Field

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

[0002] To increase product profits, current display products reduce costs by decreasing the number of chip-on-film (COF) elements in the panel.

[0003] In related technologies, in order to accommodate low-cost product architectures, displays often exhibit uneven brightness at the edges, resulting in jagged edges.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a display panel and display device.

[0006] According to one aspect of this disclosure, a display panel is provided, comprising: a substrate, including a display area and a border area disposed circumferentially around the display area; a first border located on one side of the substrate and within the border area, the first border extending along a column direction in its orthographic projection onto the substrate; and a second border located within the border area and disposed opposite to the first border in a row direction; wherein the first border and the orthographic projection of a first column of sub-pixels on the substrate, and the second border and the orthographic projection of a last column of sub-pixels on the substrate, all have overlapping portions, the ratio of the width of the overlapping portion in the row direction to the width of the orthographic projection of the corresponding column of sub-pixels on the substrate in the row direction is greater than or equal to 1 / 2.

[0007] In an exemplary embodiment of this disclosure, the ratio of the width of the overlapping portion in the row direction to the width of the orthographic projection of the corresponding column sub-pixel onto the substrate in the row direction is greater than or equal to 3 / 4 and less than or equal to 1.

[0008] In an exemplary embodiment of this disclosure, the first column of sub-pixels and the last column of sub-pixels have the same width in the row direction when projected onto the substrate.

[0009] In an exemplary embodiment of this disclosure, the first column of sub-pixels and the last column of sub-pixels have a first width in the row direction when projected onto the substrate, and the sub-pixels of other pixel columns have a second width in the row direction when projected onto the substrate, wherein the first width is smaller than the second width.

[0010] In an exemplary embodiment of this disclosure, the subpixels of other pixel columns have a third width in the column direction when projected onto the substrate, and the ratio of the first width to the third width is 1 to 2.

[0011] In an exemplary embodiment of this disclosure, the ratio of the first width to the second width is 1 / 3 to 2 / 3.

[0012] In an exemplary embodiment of this disclosure, the ratio of the first width to the second width is less than or equal to 1 / 3, and the orthographic projections of the first border and the second border onto the substrate cover the orthographic projections of the first column of sub-pixels and the last column of sub-pixels onto the substrate.

[0013] In an exemplary embodiment of this disclosure, the ratio of the first width to the second width is less than or equal to 2 / 3, and the ratio of the width of the overlapping portion in the row direction to the width of the orthogonal projection of the corresponding column sub-pixel on the substrate in the row direction is 3 / 4 to 1.

[0014] In an exemplary embodiment of this disclosure, the sub-pixel of any nth pixel column has a second width in the row direction and a third width in the column direction when projected onto the substrate, and the ratio of the second width to the third width is greater than or equal to 3, where n is a natural number greater than 1 and less than N, and N is the number of pixel columns in the display panel.

[0015] In an exemplary embodiment of this disclosure, the display panel includes n data signal lines and m columns of sub-pixels, wherein the orthographic projection of any column of sub-pixels on the substrate is located between the orthographic projections of two adjacent data signal lines on the substrate, where m = n + 1, and n and m are both natural numbers greater than or equal to 1.

[0016] In an exemplary embodiment of this disclosure, in each sub-pixel of the same pixel column, sub-pixels located in odd-numbered rows are connected to the same data signal line, and sub-pixels located in even-numbered rows are connected to another data signal line; in two adjacent columns of sub-pixels distributed on both sides of the same data signal line, the even-numbered rows of sub-pixels in the previous column and the odd-numbered rows of sub-pixels in the next column are connected to the same data signal line; in two columns of sub-pixels distributed between two adjacent data signal lines, sub-pixels located in odd-numbered rows are connected to the previous data signal line, and sub-pixels located in even-numbered rows are connected to the next data signal line.

[0017] In an exemplary embodiment of this disclosure, the width of the overlapping portion in the row direction is 163.35 to 326.7 μm.

[0018] In an exemplary embodiment of this disclosure, the first width is 162–327 μm, and the second width is greater than 485 μm.

[0019] The display panel includes multiple data signal lines. The data signal lines extend along the column direction in the orthographic projection of the substrate and have a minimum width of a fourth width in the row direction. The ratio of the first width to the fourth width is 14 to 29.

[0020] According to a second aspect of this disclosure, a display device is also provided, including the display panel described in any embodiment of this disclosure.

[0021] The display panel disclosed herein has a first border that at least partially obscures the first column of sub-pixels, and the ratio of the width of the obscured portion to the width of the first column of sub-pixels is greater than 1 / 2. That is, the width of the first column of sub-pixels obscured by the first border is greater than the width not obscured by the first border. In other words, by obscuring the main portion of the first column of sub-pixels by the first border, the uneven brightness at the edges caused by the lack of pre-filling in the first column of sub-pixels can be mitigated to some extent. Similarly, by obscuring the main portion of the last column of sub-pixels by the second border, the uneven brightness at the edges caused by the lack of pre-filling in the last column of sub-pixels can be mitigated. Thus, the display panel of this disclosure can effectively improve the display defects caused by uneven brightness at the edges.

[0022] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0036] Figure 1 This is a schematic diagram of the structure of a display panel according to one embodiment of the present disclosure. Figure 2 for Figure 1 The image shows a magnified view of the left and right side borders. The dashed boxes in the image represent magnified views of a single subpixel. Figure 1and Figure 2 As shown, the display panel may include a substrate BP, a first border GPL, and a second border GPR. The substrate BP includes a display area and a border area circumferentially arranged around the display area. The first border GPL is located on one side of the substrate BP and within the border area. The orthographic projection of the first border GPL onto the substrate BP extends along the column direction Y. The second border GPR is located within the border area and is disposed opposite to the first border GPL in the row direction X. The first border GPL and the orthographic projection of the first column sub-pixel Pixel-F onto the substrate BP, as well as the second border GPR and the orthographic projection of the last column sub-pixel Pixel-L onto the substrate BP, all have overlapping portions. The ratio of the width of the overlapping portion in the row direction X to the width of the corresponding column sub-pixel's orthographic projection onto the substrate BP in the row direction X is greater than or equal to 1 / 2.

[0037] The display panel disclosed herein at least partially obscures the first column of sub-pixels Pixel-F, and the ratio of the width of the obscured portion to the width of the first column of sub-pixels Pixel-F is greater than or equal to 1 / 2. That is, the width of the first column of sub-pixels Pixel-F obscured by the first border GPL is greater than or equal to the width not obscured by the first border GPL. In other words, by obscuring the main portion of the first column of sub-pixels Pixel-F by the first border GPL, the uneven brightness at the edges caused by the lack of pre-charging in the first column of sub-pixels Pixel-F can be mitigated or eliminated to a certain extent. Similarly, by obscuring the main portion of the last column of sub-pixels Pixel-L by the second border GPR, the uneven brightness at the edges caused by the lack of pre-charging in the last column of sub-pixels Pixel-L can be mitigated. Thus, the display panel of this disclosure can effectively improve the display defects caused by uneven brightness at the edges.

[0038] The display panel disclosed herein can be a liquid crystal display panel. Figure 3 This is a cross-sectional schematic diagram of a display panel according to one embodiment of the present disclosure, as shown below. Figure 3As shown, the liquid crystal display panel may include a color filter substrate and a driving substrate disposed opposite each other. The color filter substrate may include a first substrate BP1, with a bezel and a CL disposed on the first substrate BP1. The driving substrate may include a second substrate BP2, with data signal lines Data, pixel electrodes Vpixel, and a common electrode Vcon disposed on the second substrate BP2. Based on this, the orthographic projection of the first bezel GPL and the first column of sub-pixels Pixel-F onto the substrate BP, and the orthographic projection of the second bezel GPR and the last column of sub-pixels Pixel-L onto the substrate BP, as described in this disclosure, can be specifically understood as the orthographic projection of the first bezel GPL and the first column of sub-pixels Pixel-F onto the first substrate BP1, and the orthographic projection of the second bezel GPR and the last column of sub-pixels Pixel-L onto the first substrate BP1.

[0039] like Figure 1 As shown, the display panel disclosed herein may include an outer bezel (BMO) and an inner bezel (BMI). In addition to the first bezel (GPL) and the second bezel (GPR) positioned opposite each other in the row direction (X) as described above, the outer bezel (BMO) may also include a third bezel (DP) and a fourth bezel (DPO) positioned opposite each other in the column direction (Y). Both the outer bezel (BMO) and the inner bezel (BMI) can be black matrices. The outer bezel (BMO) is mainly used to prevent light leakage from sub-pixels at the edge of the display area. The inner bezel (BMI) can be grid-like, and can isolate adjacent light-emitting areas to prevent light leakage and color mixing; further details are omitted here.

[0040] For ease of description, this disclosure refers only to the first column of sub-pixels, Pixel-F. Figure 2 The leftmost column of sub-pixels and the last column of sub-pixels, Pixel-L, are Figure 2 Let's take the rightmost column of sub-pixels as an example. It's understandable that... Figure 2 From left to right, the sub-pixels are arranged as follows: first column Pixel-F, second column Pixel, ..., second to last column Pixel, and last column Pixel-L.

[0041] Figure 4 for Figure 1 A magnified view of the first border area, as shown below. Figure 4As shown, the first border GPL and the first column of sub-pixels Pixel-F have an overlapping portion in their orthogonal projections onto the substrate BP, meaning that the first border GPL occupies a portion of the first column of sub-pixels Pixel-F. The ratio of the width of the overlapping portion in the row direction X to the width of the corresponding column of sub-pixels projected onto the substrate BP in the row direction X is greater than 1 / 2, indicating that the width of the first column of sub-pixels Pixel-F that is occupied by the first border GPL is greater than the width that is not occupied by the first border GPL. In other words, the first border GPL of this disclosure needs to occupy the main part of the first column of sub-pixels Pixel-F, thereby reducing the overall luminous brightness of the first column of sub-pixels Pixel-F. In this way, the brightness difference caused by some sub-pixels not being able to pre-charge and some sub-pixels being able to pre-charge in the first column of sub-pixels Pixel-F is reduced, that is, the contrast between brightness and dark areas is reduced, thereby greatly reducing the uneven brightness and darkness at the edges of the first column of sub-pixels Pixel-F caused by some sub-pixels not being able to pre-charge. In some embodiments, the ratio of the width of the overlapping portion in the row direction X to the width of the corresponding column sub-pixel projected onto the substrate BP in the row direction X can also be equal to 1 / 2. That is, the first border GPL exactly covers half the width of the first column sub-pixel Pixel-F, so that the width of the first column sub-pixel Pixel-F covered by the first border GPL is the same as the width not covered by the first border GPL. In this way, compared with the prior art, the contrast between the bright and dark parts in the first column sub-pixel can also be reduced, thereby mitigating the uneven brightness at the edges. For example, the width of the overlapping portion in the row direction X can be 163.35 to 326.7 μm.

[0042] It should be understood that the occlusion relationship between the second border GPR and the last column of sub-pixels Pixel-L can be the same as the occlusion relationship between the first border GPL and the first column of sub-pixels Pixel-F, which will not be elaborated here.

[0043] Figure 5 According to another embodiment of this disclosure Figure 1 A magnified view of the first border area, as shown below. Figure 5 As shown, when the ratio of the width of the overlapping portion in the row direction X to the width of the orthographic projection of the first column sub-pixel Pixel-F onto the substrate BP in the row direction X is 1, that is, the first border GPL completely blocks the first column sub-pixel Pixel-F. Under this structure, it is equivalent to the first column sub-pixel Pixel-F not being displayed. The effective display area of ​​the display panel actually starts from the second column sub-pixel. In this way, all sub-pixels of the second column can be pre-charged, that is, the second column sub-pixels do not have the problem of uneven brightness. Therefore, under this structure, the edge brightness unevenness phenomenon at the first border GPL can be completely eliminated.

[0044] Similarly, the second bezel GPR and the last column of sub-pixels Pixel-L have an overlapping portion in their orthogonal projections onto the substrate BP. That is, the second bezel GPR occludes the last column of sub-pixels Pixel-L, specifically obscuring the main portion of the last column of sub-pixels Pixel-L. This improves and eliminates the uneven edge brightness that appears on the second bezel GPR side of the display panel. Therefore, the display panel of this disclosure can effectively solve the problem of uneven edge brightness at the two bezel positions.

[0045] The row width of the first column of sub-pixels in this disclosure can be the same as or different from the row width of the last column of sub-pixels. When the row widths of the first and last columns of sub-pixels are the same, the panel manufacturing process can be simplified. The following description uses the example of the first and last columns of sub-pixels having the same row width as the last column of sub-pixels as an example. In other embodiments, the row widths of the first and last columns of sub-pixels can also be different, and these are all within the protection scope of this disclosure.

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] Figure 6 This is a schematic diagram illustrating the connection between a sub-pixel and a data signal line according to one embodiment of the present disclosure, as shown below. Figure 6 As shown, in the display panel of this disclosure, among the sub-pixels in the same pixel column, the sub-pixels located in odd-numbered rows are connected to the same data signal line, and the sub-pixels located in even-numbered rows are connected to another data signal line; among two adjacent columns of sub-pixels distributed on both sides of the same data signal line, the sub-pixels in the even-numbered rows of the previous column and the sub-pixels in the odd-numbered rows of the next column are connected to the same data signal line; among two columns of sub-pixels distributed between two adjacent data signal lines, the sub-pixels located in odd-numbered rows are connected to the previous data signal line, and the sub-pixels located in even-numbered rows are connected to the next data signal line.

[0048] For example, taking the second pixel column as an example, the odd-numbered rows of sub-pixels in the first, third, fifth, etc., of the second pixel column are all connected to the first data signal line DT1, while the even-numbered rows of sub-pixels in the second, fourth, sixth, etc., are all connected to the second data signal line DT2. In this way, some sub-pixels in the second pixel column can be pre-charged using the first data signal line DT1, and the remaining sub-pixels can be pre-charged using the second data signal line Data.

[0049] The fourth and fifth column sub-pixels are distributed on both sides of the third data signal line DT3. Then, the second row of sub-pixels, the fourth row of sub-pixels, the sixth row of sub-pixels, etc., of the fourth pixel column, and the first row of sub-pixels, the third row of sub-pixels, the fifth row of sub-pixels, etc., of the fifth pixel column, are all connected to the third data signal line DT3.

[0050] If the first pixel column and the second pixel column are located between the first data signal line and the second data signal line, then the odd-numbered rows of sub-pixels in the first pixel column and the second pixel column, such as the first row of sub-pixels, the third row of sub-pixels, the fifth row of sub-pixels, etc., are all connected to the first data signal line, and the even-numbered rows of sub-pixels in the first pixel column and the second pixel column, such as the second row of sub-pixels, the fourth row of sub-pixels, the sixth row of sub-pixels, etc., are all connected to the second data signal line.

[0051] The following is based on Figure 6 The principle behind the jagged edges on the side bezels of the display panel in this disclosure will be explained using an example. Figure 6 As shown, taking the first column of sub-pixels Pixel-F as an example, the first data signal line Data connects some sub-pixels in the first column, and the remaining sub-pixels in the first column are connected to the second data signal line Data. This causes the sub-pixels connected to the first data signal line Data to be unable to be pre-charged, meaning some sub-pixels in the first column cannot be pre-charged. However, while charging the sub-pixels connected to it using the first data signal line Data, the remaining sub-pixels in the first column connected to it can be pre-charged using the second data signal line Data. This results in some sub-pixels in the first column being able to be pre-charged while others are not, causing uneven brightness in the first column of sub-pixels Pixel-F, which manifests as jagged edges and poor display quality. Similarly, the last column of sub-pixels Pixel-F will also exhibit uneven brightness and jagged edges when displayed. As described above, the present disclosure display panel improves and eliminates the display defect by adjusting the occlusion relationship between the first border GPL and the first column of sub-pixels Pixel-F and the occlusion relationship between the second border GPR and the last column of sub-pixels Pixel-L.

[0052] It should be understood that the pre-charging of a sub-pixel using a certain data signal line Data as described in this disclosure means that by controlling the gate signal line Gate connected to the sub-pixel to be turned on in advance, the data signal line Data connected to the sub-pixel can write data signals to the sub-pixel in advance.

[0053] Continue to refer to Figure 6In the display panel of this disclosure, data signal lines are arranged in the gaps between two adjacent columns of sub-pixels, so that each data signal line extends in the column direction Y and is distributed sequentially at intervals in the row direction X. Furthermore, in the display panel of this disclosure, the first data signal line is located on the side of the first column sub-pixel Pixel-F away from the last column sub-pixel Pixel-L, and the last data signal line is located on the side of the last column sub-pixel Pixel-L away from the first column sub-pixel Pixel-F, so that each column of sub-pixels is located between two adjacent data signal lines.

[0054] like Figure 6 As shown, the display panel disclosed herein may include n columns of sub-pixels and m data signal lines, where m = n + 1, and n and m are both natural numbers greater than or equal to 1, meaning that the number of data signal lines is 1 more than the number of pixel columns.

[0055] In an exemplary embodiment, the ratio of the width of the overlapping portion in the row direction X to the width of the orthographic projection of the corresponding column sub-pixel onto the substrate BP in the row direction X can be greater than or equal to 3 / 4 and less than or equal to 1, for example, it can be 0.75, 0.8, 0.85, 0.9, 0.95, 1, etc. That is, the ratio of the overlap between the first border GPL and the first column of sub-pixels Pixel-F to the width of the first column of sub-pixels Pixel-F in the row direction X is greater than or equal to 3 / 4 and less than or equal to 1. Similarly, the ratio of the overlap between the second border GPR and the last column of sub-pixels Pixel-L to the width of the last column of sub-pixels Pixel-L in the row direction X is greater than or equal to 3 / 4 and less than or equal to 1. In other words, the first border GPL can completely cover the first column of sub-pixels Pixel-F or at least cover 3 / 4 of the width of the first column of sub-pixels Pixel-F in the row direction X. Likewise, the second border GPR can completely cover the last column of sub-pixels Pixel-L or at least cover 3 / 4 of the width of the last column of sub-pixels Pixel-L in the row direction X. In this way, the jagged edges of the display panel at the left and right borders can be effectively improved or completely eliminated.

[0056] like Figure 2As shown, in an exemplary embodiment, the orthographic projections of the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L onto the substrate BP have a first width d1 in the row direction, while the orthographic projections of the sub-pixels of other pixel columns onto the substrate BP have a second width d2 in the row direction. The first width d1 is smaller than the second width d2. This is equivalent to reducing the row-direction width of the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L to achieve the aforementioned occlusion relationship between the first border GPL and the first column of sub-pixels Pixel-F, and the second border GPR and the last column of sub-pixels Pixel-L, thereby causing the row-direction width of the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L to be smaller than the width of the sub-pixels in other columns. For example, the first width d1 can be 162–327 μm, and the second width d2 can be greater than or equal to 485 μm. In some products, the first width d1 can specifically be 163.35 μm, and the second width d2 can specifically be 490.05 μm.

[0057] In an exemplary embodiment, the ratio of the first width d1 to the second width d2 can be 1 / 3 to 2 / 3, for example, 1 / 3, 1 / 2, 3 / 5, 2 / 3, etc. For example, the row widths of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L can be reduced to 1 / 3 to 2 / 3 of the row widths of the other column sub-pixels, based on the row widths of the other column sub-pixels, to achieve the purpose of reducing the row widths of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L, thereby improving the edge jaggedness.

[0058] In an exemplary embodiment, the ratio of the first width d1 to the second width d2 may also be less than or equal to 1 / 3, and the orthographic projections of the first border GPL and the second border GPR onto the substrate BP correspondingly cover the orthographic projections of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L onto the substrate BP. For example, in some products, the row width of the first column sub-pixel Pixel-F and the row width of the last column sub-pixel Pixel-L may be reduced to 1 / 3 of the row width of the other columns of sub-pixels, thereby making the ratio of the first width d1 to the second width d2 equal to 1 / 3. Alternatively, in other products, after reducing the row width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L to 1 / 3 of the row width of the other columns of sub-pixels, the space saved by the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L may be further allocated to the sub-pixels of other columns, thereby increasing the row width of the other columns of sub-pixels, thus making the ratio of the first width d1 to the second width d2 less than 1 / 3.

[0059] In an exemplary embodiment, the ratio of the first width d1 to the second width d2 may also be less than or equal to 2 / 3, and the ratio of the width of the overlapping portion in the row direction to the width of the corresponding column sub-pixel projected onto the substrate BP in the row direction is 3 / 4 to 1. For example, in some products, the row direction width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L may be reduced to 2 / 3 of the row direction width of the other column sub-pixels, thereby making the ratio of the first width d1 to the second width d2 equal to 2 / 3. Alternatively, in other products, after reducing the row direction width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L to 2 / 3 of the row direction width of the other column sub-pixels, the space saved by the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L may be further allocated to the other column sub-pixels, thereby increasing the row direction width of the other column sub-pixels, thereby making the ratio of the first width d1 to the second width d2 less than 2 / 3.

[0060] In some embodiments of this disclosure, the row width of the first column of sub-pixels Pixel-F can be reduced to 1 / 3 of its original width, while keeping the row width of the first border GPL unchanged. In this way, the orthographic projection of the first border GPL onto the substrate BP can completely cover the orthographic projection of the first column of sub-pixels Pixel-F onto the substrate BP. Figure 5 The structure shown completely obscures the first column of sub-pixels, Pixel-F. In this structure, the first column of sub-pixels, Pixel-F, is obscured by the first border GPL and is no longer displayed. The display panel actually starts displaying from the second column of sub-pixels. Therefore, there is no uneven brightness on the first border GPL side, meaning this structure completely solves the jagged edge problem on the first border GPL side.

[0061] Similarly, the row width of the last column of sub-pixels Pixel-L can be reduced to 1 / 3 of its original width, while keeping the row width of the second border GPR unchanged. This allows the second border GPR to completely block the last column of sub-pixels Pixel-L, so that the actual display area of ​​the display panel ends at the second-to-last column of sub-pixels. Therefore, there will be no uneven brightness problem on the second border GPR side.

[0062] Figure 7 This is a partial enlarged view of the left and right side borders according to another embodiment of this disclosure, such as... Figure 7As shown, comparing the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L with the sub-pixels of other columns, it can be seen that the row width of the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L is significantly reduced compared to the row width of the sub-pixels of other columns, reduced to 1 / 3 of the row width of the sub-pixels of other columns. Thus, the first border GPL can completely cover the first column of sub-pixels Pixel-F, and the second border GPR can completely cover the last column of sub-pixels Pixel-L.

[0063] In some other embodiments of this disclosure, the row width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L can be reduced to 2 / 3 of their original size. For example, the row width of the first column sub-pixel Pixel-F can be set to 326.7 μm, and the row width of the first border GPL and the second border GPR can be increased simultaneously.

[0064] For example, by increasing the width of the first border GPL in the row direction, the ratio of the width of the overlapping part in the row direction X to the width of the first column sub-pixel Pixel-F in the row direction X can be 3 / 4. In this way, 3 / 4 of the width of each sub-pixel in the first column is blocked by the first border GPL, and only 1 / 4 of the width is used for actual display. Compared with the existing technology, the area ratio of the effective display part of the first column sub-pixel Pixel-F is reduced, thereby reducing the brightness of the first column sub-pixel Pixel-F. As mentioned above, after the brightness is reduced, the contrast between light and dark can be weakened, so that the uneven brightness is no longer obvious. This is equivalent to reducing the phenomenon of uneven brightness at the edge of the first column sub-pixel Pixel-F.

[0065] Similarly, the ratio of the width of the overlap between the second border GPR and the last column of sub-pixels Pixel-L in the row direction X to the width of the last column of sub-pixels Pixel-L in the row direction X can be 3 / 4, thereby reducing the area ratio of the effective display portion of the last column of sub-pixels Pixel-L, reducing the luminous brightness of the last column of sub-pixels Pixel-L, and thus effectively improving the uneven brightness phenomenon on the second border GPR side.

[0066] Figure 8 This is a partial enlarged view of the left and right side borders according to another embodiment of the present disclosure, as shown below. Figure 8As shown, the row width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L is reduced to 2 / 3 of the row width of the other column sub-pixels. After widening the first border GPL and the second border GPR, the main part of the first column sub-pixel Pixel-F is obscured by the first border GPL, and the main part of the last column sub-pixel Pixel-L is obscured by the second border GPR. It should be understood that the larger the ratio of the row width of the first border GPL and the second border GPR to the row width of the corresponding column sub-pixels projected onto the substrate BP, the more significant the improvement effect on the edge jaggedness of the display panel. For example, in some embodiments, after increasing the row-direction width of the first border GPL, the ratio of the width of the overlapping portion in the row-direction X to the width of the first column sub-pixel Pixel-F in the row-direction X can be 1. That is, while decreasing the width of the first column sub-pixel Pixel-F, the width of the first border GPL is increased so that the first border GPL completely covers the first column sub-pixel Pixel-F. Similarly, the second border GPR can completely cover the last column sub-pixel Pixel-L. This structure can have... Figure 5 The beneficial effect shown is that it can completely eliminate edge jaggedness.

[0067] In summary, the display panel disclosed herein can reduce the row width of the first and last column sub-pixels Pixel-L, or simultaneously increase the width of the first border GPL and the second border GPR while reducing the width of the first column sub-pixels Pixel-F and the last column sub-pixels Pixel-L, effectively solving the problem of poor edge jaggedness at the two borders of the display panel.

[0068] The space saved by reducing the row width of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L in this disclosed display panel can be allocated to other sub-pixels. For example, the saved space can be evenly distributed to other pixel columns, that is, the row width of other column sub-pixels can be increased. The advantage of this setting is that, since the data signal lines are arranged between two adjacent columns of sub-pixels, increasing the row width of other column sub-pixels will increase the width between two adjacent data signal lines, thereby increasing the distance between the data signal lines and the pixel electrodes, and thus reducing the lateral coupling capacitance between the data signal lines and the pixel electrodes.

[0069] like Figure 2As shown, in an exemplary embodiment, the orthographic projection of any nth pixel column onto the substrate BP has a second width d2 in the row direction X and a third width d3 in the column direction Y. The ratio of the second width d2 to the third width d3 is greater than or equal to 3, for example, it can be 3, 3.001, 3.005, 3.006, 3.008, 3.01, 3.05, etc. Here, n is a natural number greater than 1 and less than N, and N is the number of pixel columns in the display panel. As described above, the space saved by reducing the size of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L can be used to increase the row direction X size of other pixel columns. That is, the row direction width of other sub-pixels is increased compared to the prior art, while the column direction Y width remains unchanged, thus increasing the ratio of the row direction width to the column direction Y width of other sub-pixels.

[0070] For example, in the display panel, excluding the first column of sub-pixels Pixel-F and the last column of sub-pixels Pixel-L, the width of the sub-pixels in the row direction X can be greater than 490.05μm, while the width in the column direction Y can be 163.35μm. This makes the ratio of the row width to the column width in the Y direction of the sub-pixels in the display panel greater than 3. Of course, in other embodiments, the saved space may not be amortized, that is, the row width of the other pixel columns may remain unchanged, so that the ratio of the second width d2 to the third width d3 can also be equal to 3.

[0071] It should be understood that the specific size of sub-pixels can be different in different display panels. As long as the ratio of row width to column Y width is greater than 3, the above-mentioned effect of reducing the lateral coupling capacitance between the pixel electrode and the data signal line can be achieved.

[0072] In addition, such as Figure 2 As shown, the display panel of this disclosure adjusts the row width d1 of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L while keeping the column width d3 unchanged. The ratio of the row width d1 to the column width d3 of the first column sub-pixel Pixel-F and the last column sub-pixel Pixel-L can be 1 to 2. Obviously, this ratio is smaller than the ratio of the row width to the column width of the sub-pixels in other pixel columns.

[0073] As mentioned above, the data signal lines in the display panel extend along the column direction Y in the orthogonal projection of the substrate BP. Figure 9 This is a magnified view of a first column of sub-pixels according to an embodiment of the present disclosure, such as... Figure 9As shown, in an exemplary embodiment, the minimum width of the data signal line projected onto the substrate BP in the row direction X is a fourth width d4. The ratio of the first width d1 to the fourth width d4 is 14 to 29, for example, 14, 16, 18, 20, 22, 24, 26, 28, 29, etc. As described above, the row direction width of the first column sub-pixels Pixel-F and the last column sub-pixels Pixel-L of the display panel of this disclosure is reduced compared to the sub-pixel widths of other columns, while the row direction width of the data signal line remains unchanged. Therefore, the ratio of the row direction width of the first column sub-pixels Pixel-F and the last column sub-pixels Pixel-L to the width of the data signal line is reduced compared to conventional products.

[0074] It is worth noting that, such as Figure 9 As shown, subpixels are usually irregular structures. The first width d1 of the subpixels disclosed in this invention can be determined by the following method: the maximum width of the first column subpixel Pixel-F and the last column subpixel Pixel-L projected onto the substrate BP along the row direction X is determined as the first width d1 of the first column subpixel Pixel-F and the last column subpixel Pixel-L.
