Description

Technical Field

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

[0002] Traditional display panels typically consist of multiple repeating groups of pixel units. Each pixel unit group comprises multiple pixel units, and each pixel unit includes a first color pixel, a second color pixel, and a third color pixel. In conventional pixel arrangement schemes, the center-to-center spacing of pixels of the same color in adjacent pixel units is equal in the first direction and in the second direction. The centers of each color pixel form a regular, equidistant array in both the first and second directions, presenting an overall regular and repeating pixel arrangement.

[0003] To ensure the viewing angle symmetry of the display panel, the opening centers of the light-emitting layer, color filter layer, first black matrix layer, and second black matrix layer need to be aligned. However, in actual production, deformation occurs between the multiple pixel definition layers, causing periodic displacements in the relative positions of different functional layers, and these displacements exhibit periodic differences in different areas. When the display panel uses a regular, equidistant pixel arrangement, the periodic displacements between the multiple pixel definition layers will macroscopically manifest as moiré patterns due to the small repetition period of the pixel arrangement, affecting the viewing quality of the displayed image.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this application is to provide a display device that aims to reduce or eliminate moiré patterns generated by the display device.

[0006] This application provides a display device, which includes a display panel. The display panel includes a plurality of pixel unit groups, each pixel unit group including a plurality of pixel units arranged in a row × b columns. Each pixel unit includes a first color pixel, a second color pixel, and a third color pixel. In the pixel unit group, the center of the first color pixel of the pixel unit located in the i-th row and j-th column has a first distance from the center of the first color pixel of the pixel unit located in the (i+1)-th row and j-th column in a first direction, and the center of the first color pixel of the pixel unit located in the i-th row and j-th column has a second distance from the center of the first color pixel of the pixel unit located in the (i+1)-th row and j-th column in a first direction. The center of the second color pixel of the pixel unit located in the i-th row and j-th column has a second distance from the center of the first color pixel of the pixel unit located in the (i+1)-th row and j-th column in a first direction. The center of the second color pixel of a pixel unit has a third spacing in a first direction; the center of the second color pixel of the pixel unit located in the i-th row and j+1-th column has a fourth spacing in a first direction; the center of the third color pixel of the pixel unit located in the i-th row and j-th column has a fifth spacing in a first direction; and the center of the third color pixel of the pixel unit located in the i-th row and j-th column has a sixth spacing in a first direction; wherein at least one of the first spacing, the second spacing, the third spacing, the fourth spacing, the fifth spacing, and the sixth spacing is not equal to 0.

[0007] In the above-described display device, the first spacing is equal to the third spacing, the third spacing is equal to the fifth spacing; the second spacing is equal to the fourth spacing, the fourth spacing is equal to the sixth spacing; and the first spacing is not equal to the second spacing.

[0008] In the above-mentioned display device, the first spacing, the third spacing, and the fifth spacing are all equal to 0; the second spacing, the fourth spacing, and the sixth spacing are all not equal to 0.

[0009] In the above-mentioned display device, the first spacing, the third spacing, and the fifth spacing are all not equal to 0; the second spacing, the fourth spacing, and the sixth spacing are all equal to 0.

[0010] In the above-described display device, the first spacing is equal to the third spacing, the third spacing is equal to the fifth spacing; the second spacing is equal to the fourth spacing, the fourth spacing is equal to the sixth spacing; and the first spacing is equal to the second spacing.

[0011] In the above-described display device, the first pitch is not equal to the third pitch, the third pitch is not equal to the fifth pitch, the second pitch is not equal to the fourth pitch, and the fourth pitch is not equal to the sixth pitch.

[0012] In the above-described display device, the first pitch is equal to the third pitch, the third pitch is equal to the fifth pitch; the second pitch is not equal to the fourth pitch, and the fourth pitch is not equal to the sixth pitch.

[0013] In the above-mentioned display device, the first pitch, the third pitch, and the fifth pitch are all equal to 0, and one of the second pitch, the fourth pitch, and the sixth pitch is not equal to 0; or the first pitch, the third pitch, and the fifth pitch are all not equal to 0.

[0014] In the above-described display device, the first pitch is not equal to the third pitch, the third pitch is not equal to the fifth pitch; the second pitch is equal to the fourth pitch, and the fourth pitch is equal to the sixth pitch.

[0015] In the above-described display device, one of the first pitch, the third pitch, and the fifth pitch is not equal to 0, and the second pitch, the fourth pitch, and the sixth pitch are all equal to 0; or the second pitch, the fourth pitch, and the sixth pitch are all not equal to 0.

[0016] The display device provided in this application employs a non-equidistant pixel arrangement scheme within the pixel unit group, ensuring that at least one of the first, second, third, fourth, fifth, and sixth spacings is not equal to 0. This causes a positional shift in the centers of corresponding color pixels in adjacent rows within the same column, in the first direction. This non-equidistant pixel arrangement scheme alters the regularity and periodicity of traditional equidistant pixel arrangements, increasing the repetition period of the pixel unit group. When deformation occurs between multiple pixel definition layers during the display panel's manufacturing process, the increased repetition period of the pixel unit group weakens the interaction between the periodic displacements between the multiple pixel definition layers and the period of the pixel arrangement, thereby reducing the probability and visibility of moiré patterns. Specifically, in a traditional equidistant pixel arrangement, the centers of each color pixel form a regular equidistant array in both the first and second directions. This regularity makes it easy for the periodic displacements between multiple pixel definition layers to interfere with the period of the pixel arrangement, resulting in noticeable moiré patterns on a macroscopic scale. The technical solution of this application breaks the regular periodicity of pixel arrangement by introducing a non-equidistant pixel arrangement. This results in a different spacing in the first direction between the corresponding color pixels in the i-th row, j-th column and the pixel unit in the (i+1)-th row, j-th column compared to the spacing in the first direction between the corresponding color pixels in the i-th row, j+1-th column and the pixel unit in the (i+1)-th row, j+1-th column, thus forming a non-periodic pixel distribution. This non-periodic pixel distribution reduces the interference between periodic displacements between multiple pixel definition layers and the pixel arrangement, thereby reducing or eliminating macroscopic moiré patterns and improving the viewing quality of the displayed image.

[0017] Furthermore, the technical solution of this application achieves the effect of reducing moiré patterns simply by adjusting the arrangement of pixel units without adding additional film layers. Compared with technical solutions that require additional film layers or other complex processes, the technical solution of this application reduces production costs, simplifies the production process, and improves production efficiency. At the same time, the technical solution of this application maintains the symmetry of the opening centers of the light-emitting layer, color filter layer, first black matrix layer, and second black matrix layer, ensuring the viewing angle symmetry of the display panel and meeting the functional requirements of privacy display.

[0021] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0022] The terms “first,” “second,” and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms “multiple,” and similar words mean two or more, unless otherwise expressly specified.

[0023] The technical solutions of different embodiments of this application can be combined with each other.

[0024] The display device provided in the embodiments of this application may be, for example, an OLED (Organic Light Emitting Diode) display device, a Mini-LED display device, or a Micro-LED display device. The embodiments of this application will be described using an OLED display device as an example.

[0025] Embodiments of this application provide a display device, which includes a display panel. The display panel includes a plurality of pixel unit groups, each pixel unit group including a plurality of pixel units PX arranged in a row × b column, and the pixel unit PX including a first color pixel PX1, a second color pixel PX2, and a third color pixel PX3. In one embodiment of this application, a equals 2, b equals 2, as shown below. Figure 3 As shown, each pixel unit group consists of four pixel units PX.

[0026] like Figure 1 As shown, in one embodiment of this application, the display device further includes a timing controller TCON and a source driver chip SDIC. The display panel includes a gate driver circuit GOA, multiple gate lines GL, multiple light emission control signal lines EM, multiple data lines DL, multiple first power lines VDD, and multiple second power lines VSS. The timing controller TCON receives externally input image data and converts it into a signal format suitable for display on the display panel. The timing controller TCON transmits the converted image data to the source driver chip SDIC. The source driver chip SDIC converts the received image data into an analog voltage signal and transmits it to the pixel unit via the data lines DL. The gate driver circuit GOA scans the gate lines GL line by line, and the gate lines GL control the turning on and off of the pixel units. The light emission control signal lines EM control the light emission timing of the pixel units, and the first power lines VDD and second power lines VSS provide power to the pixel units.

[0027] like Figure 2As shown, the display panel adopts a privacy protection scheme. From bottom to top, the display panel includes a substrate SUB, a driving device layer, a pixel limiting layer BPDL, an anode layer AND, an electroluminescent layer EL, a cathode layer CAT, a packaging layer TFE, a touch device layer DOT, a first black matrix layer BM1, a color filter layer CF, a first passivation layer PAS1, a second passivation layer PAS2, a second black matrix layer BM2, a third passivation layer PAS3, and a cover plate MOD.

[0028] A driving device layer is formed on the substrate SUB, which drives the light-emitting device to emit light. The driving device layer includes thin-film transistors and capacitors. The thin-film transistors control the operating state of the pixel unit PX in response to signals transmitted by the gate line GL and the data line DL. A pixel defining layer BPDL is formed above the driving device layer. The pixel defining layer BPDL has multiple recessed areas. The anode layer AND and the electroluminescent layer EL are disposed within the recessed areas of the pixel defining layer BPDL. The cathode layer CAT covers the electroluminescent layer EL. The encapsulation layer TFE covers the cathode layer CAT and is used to encapsulate and protect the light-emitting device composed of the anode layer AND, the electroluminescent layer EL, and the cathode layer CAT. A touch device layer DOT is disposed on the encapsulation layer TFE and is used to implement touch functionality. A first black matrix layer BM1 and a color filter layer CF are disposed above the touch device layer DOT. The first black matrix layer BM1 is used to block the light emitted by the display panel at wide viewing angles to achieve a privacy protection effect. The color filter layer CF is used to filter the light emitted by the electroluminescent layer EL. The center of each color filter element in the color filter layer CF is aligned with the center of the corresponding opening in the first black matrix layer BM1. The first passivation layer PAS1 covers both the first black matrix layer BM1 and the color filter layer CF. The second passivation layer PAS2 is disposed on the first passivation layer PAS1, and the second black matrix layer BM2 is disposed on the second passivation layer PAS2. The second black matrix layer BM2 is used to further enhance the privacy protection effect. The center of each color filter element in the color filter layer CF is aligned with the center of the corresponding opening in the second black matrix layer BM2. The second black matrix layer BM2 and the second passivation layer PAS2 are jointly covered by the third passivation layer PAS3, and the cover plate MOD is disposed on the third passivation layer PAS3.

[0029] By employing multiple layers of shielding in the first black matrix layer BM1 and the second black matrix layer BM2, the light emitted from the display panel at a wide viewing angle is effectively blocked, achieving a wide-viewing-angle privacy protection effect. Through different opening designs or stacking differences between adjacent pixel units PX, such as using different opening sizes or stacking methods for privacy-protected pixels and non-privacy-protected pixels in the color filter layer CF and the first and second black matrix layers BM1 and BM2, pixels with different display viewing angles, including both privacy-protected and non-privacy-protected pixels, are achieved. Terminal devices including the display panel can selectively drive corresponding pixel groups in different operating modes by separately controlling the privacy-protected or non-privacy-protected pixels, thereby achieving dynamic privacy protection and enabling the same display panel to switch between privacy-protected and non-privacy-protected modes.

[0030] To ensure viewing symmetry, during the layout design phase, the centers of the luminescent areas of the electroluminescent layer (EL), the color filter blocks in the color filter layer (CF), the openings of the first black matrix layer (BM1), and the openings of the second black matrix layer (BM2) are designed to coincide, maintaining central symmetry. However, in actual production, due to potential deformation and alignment errors between the multi-layer pixel limiting layer (BPDL) and corresponding process layers, the relative positions of different functional layers often exhibit slight periodic displacements. These periodic displacements, combined with the periodic arrangement of the pixels themselves, macroscopically manifest as noticeable moiré patterns, thus affecting normal viewing, especially in display panels with multi-layer privacy shielding stacking.

[0031] To address the aforementioned issues, this application introduces a non-equidistant pixel arrangement while maintaining symmetry between the centers of the luminescent region of the electroluminescent layer EL, the color filter block in the color filter layer CF, the opening of the first black matrix layer BM1, and the opening of the second black matrix layer BM2. Specifically, the display panel uses pixel unit groups as basic repeating units, and slightly offsets the pixel center arrangement within each pixel unit group. In at least one direction (e.g., the first direction X), the centers of adjacent pixels do not completely overlap, thereby breaking the strict equidistant relationship of traditional pixel arrays in that direction and increasing the macroscopic repeating period of the pixel unit group. Even if there are periodic deformations between multiple pixel-defining layers during production, the interference conditions between the periodic deformation and the pixel arrangement are no longer strongly superimposed due to the modulation of the pixel period, thus reducing moiré patterns caused by the coherence of periodic displacement and pixel period. In this way, without increasing the number of additional film layers or changing the existing anti-spy stacking method, by adjusting the relative positional relationship of pixels at the layout level, the matching degree between periodic deformation and pixel period is reduced, thereby reducing the probability and visibility of moiré patterns.

[0032] In one embodiment of this application, such as Figure 3As shown, the first color pixel PX1 is a red pixel, the second color pixel PX2 is a green pixel, and the third color pixel PX3 is a blue pixel. In pixel unit PX, the lines connecting the centers of the first color pixel PX1, the second color pixel PX2, and the third color pixel PX3 form a triangle. Along the second direction Y (e.g., the column direction), the center of the first color pixel PX1 is aligned with the center of the second color pixel PX2, and the center of the third color pixel PX3 is located between the first color pixel PX1 and the second color pixel PX2. Furthermore, the center of the third color pixel PX3 and the center of the first color pixel PX1 have a certain distance between them along the first direction X (e.g., the row direction). This layout is beneficial for sub-pixel light mixing and for tolerance under mask opening deformation.

[0033] In any row of pixel units PX, the line connecting the center of the first-color pixel PX1 in the j-th column PX and the center of the first-color pixel PX1 in the (j+1)-th column PX is parallel to the first direction X; the line connecting the center of the second-color pixel PX2 in the j-th column PX and the center of the second-color pixel PX2 in the (j+1)-th column PX is parallel to the first direction X; and the line connecting the center of the third-color pixel PX3 in the j-th column PX and the center of the third-color pixel PX3 in the (j+1)-th column PX is parallel to the first direction X. This means that within the same row, pixels of the same color maintain a consistent position in the second direction Y, which helps maintain pixel regularity and display uniformity in the second direction Y.

[0034] In one embodiment of this application, the display panel employs a multiple repeating unit arrangement. Taking each repeating unit as 2 rows × 2 columns as an example, each pixel unit group includes four pixel units PX. In a conventional arrangement, each color pixel forms a regular, equally spaced array in the first direction X and the second direction Y. This application introduces a non-equally spaced arrangement based on this. To describe the non-equally spaced arrangement, multiple sets of row spacing parameters L1 to L6 are defined in the pixel unit group to characterize the offset relationship between adjacent rows of each color pixel in the first direction X.

[0035] Within a pixel unit group, the center of the first color pixel PX1 of pixel unit PX located in the i-th row and j-th column has a first spacing L1 with the center of the first color pixel PX1 of pixel unit PX located in the (i+1)-th row and j-th column in the first direction X. The center of the second color pixel PX2 of pixel unit PX located in the i-th row and j-th column has a third spacing L3 with the center of the second color pixel PX2 of pixel unit PX located in the (i+1)-th row and j-th column in the first direction X. The center of the third color pixel PX3 of pixel unit PX located in the i-th row and j-th column has a fifth spacing L5 with the center of the third color pixel PX3 of pixel unit PX located in the (i+1)-th row and j-th column in the first direction X. Similarly, the center of the first color pixel PX1 of the pixel unit PX located in the i-th row and j+1-th column has a second spacing L2 with the center of the first color pixel PX1 of the pixel unit PX located in the i+1-th row and j+1-th column in the first direction X; the center of the second color pixel PX2 of the pixel unit PX located in the i-th row and j+1-th column has a fourth spacing L4 with the center of the second color pixel PX2 of the pixel unit PX located in the i+1-th row and j+1-th column in the first direction X; and the center of the third color pixel PX3 of the pixel unit PX located in the i-th row and j+1-th column has a sixth spacing L6 with the center of the third color pixel PX3 of the pixel unit PX located in the i+1-th row and j+1-th column in the first direction X.

[0036] The aforementioned first spacing L1 to sixth spacing L6 are used to quantify the relative offset of the centers of corresponding color pixels in the first direction X between adjacent rows. When the state in which the centers of a pair of reference pixels located in the same column but not in the same row are completely aligned in the first direction X is defined as the baseline state, the spacing between the centers of the two pixels in the first direction X in this baseline state is 0. That is, when a certain spacing Lk (k takes any value from 1 to 6) is equal to 0, it means that the corresponding color pixels located in the same column but not in the same row have no relative offset in the first direction X, and the corresponding color pixels in each row maintain the original equal spacing alignment; when a certain spacing Lk is not equal to 0, it means that the corresponding pixels located in the same column but not in the same row have generated a certain offset in the first direction X, that is, they have deviated from the original equal spacing arrangement. Therefore, when at least one of the first spacings L1 to sixth spacing L6 is not equal to 0, that is, at least one type of pixel center is no longer completely aligned with the center of the pixel in other rows in the same column in the first direction X, thereby breaking the original equal spacing arrangement and constituting the pixel non-equal spacing arrangement method as referred to in this application.

[0037] In one embodiment of this application, the distance between the center of the first color pixel PX1 of pixel unit PX located in the i-th row and j-th column and the center of the first color pixel PX1 of pixel unit PX located in the i-th row and j-th column is equal to the distance between the center of the first color pixel PX1 of pixel unit PX located in the i+1-th row and j-th column and the center of the first color pixel PX1 of pixel unit PX located in the i+1-th row and j-th column; the distance between the center of the second color pixel PX2 of pixel unit PX located in the i-th row and j-th column and the center of the second color pixel PX2 of pixel unit PX located in the i-th row and j-th column is equal to the distance between the center of the second color pixel PX2 of pixel unit PX located in the i-th row and j-th column. The spacing is equal to the distance between the center of the second-color pixel PX2 in the (i+1)th row and (j)th column of pixel unit PX and the center of the second-color pixel PX2 in the (i+1)th row and (j+1)th column of pixel unit PX; the distance between the center of the third-color pixel PX3 in the (i)th row and (j)th column of pixel unit PX and the center of the third-color pixel PX3 in the (i+1)th row and (j+1)th column of pixel unit PX is equal to the distance between the center of the third-color pixel PX3 in the (i+1)th row and (j+1)th column of pixel unit PX. Therefore, in pixel units PX of different rows, the inter-column spacing of pixels of the same color remains consistent in the first direction X, avoiding the introduction of new bright and dark stripes in the horizontal direction.

[0038] In Example 1, as Figure 3As shown, the first spacing L1 is equal to the third spacing L3 (in pixel unit PX, the center of the first color pixel PX1 is aligned with the center of the second color pixel PX2 in the first direction X), and the first spacing L1 is equal to the fifth spacing L5. Simultaneously, the second spacing L2 is equal to the fourth spacing L4 and the sixth spacing L6, but the first spacing L1 and the second spacing L2 are not equal. In this way, different color pixels in the same column (e.g., column j) have the same offset in the first direction X, while different color pixels in another column (e.g., column j+1) also have the same offset in the first direction X, but the offsets between the two columns are different. In a specific example, the first spacing L1, the third spacing L3, and the fifth spacing L5 are all equal to 0, while the second spacing L2, the fourth spacing L4, and the sixth spacing L6 are not equal to 0. In this case, the pixel unit PX in the j-th column is perfectly aligned with the first-color pixels PX1, the second-color pixels PX2, and the third-color pixels PX3 in adjacent rows along the first direction X. The pixel unit PX in the (j+1)-th column is shifted along the first direction X along the same direction. Alternatively, the settings can be reversed: the first spacing L1, the third spacing L3, and the fifth spacing L5 are not equal to 0, while the second spacing L2, the fourth spacing L4, and the sixth spacing L6 are all equal to 0. This causes the pixel unit PX in the j-th column to shift along the first direction X along adjacent rows, while the pixel unit PX in the (j+1)-th column remains aligned along the first direction X along adjacent rows. By shifting only one column or a portion of columns, the overall repetition cycle of the pixel arrangement is extended while minimizing layout changes. The values ​​of the first spacing L1, the second spacing L2, the third spacing L3, the fourth spacing L4, the fifth spacing L5, and the sixth spacing L6 range from 0 micrometers to 10 micrometers.

[0039] In Embodiment 2, the first spacing L1 is equal to the second spacing L2, the second spacing L2 is equal to the third spacing L3, the fourth spacing L4 is equal to the fifth spacing L5, the fifth spacing L5 is equal to the sixth spacing L6, and the first spacing L1 is further equal to the fourth spacing L4. In this case, the offset of each color pixel in each column between adjacent rows is the same, that is, the entire pixel unit group is translated by the same amount in the first direction X. At this time, when viewed from within a pixel unit group, the rows still appear to be aligned, but when stitched with adjacent pixel unit groups, the pixel unit groups form a new period on a larger scale, thereby weakening the overlap with the periodic deformation caused by the process. The first spacing L1 to the sixth spacing L6 in this embodiment are any values ​​in the range of 0 micrometers to 10 micrometers, for example, all are 5 micrometers.

[0040] In Example 3, the first spacing L1 is not equal to the third spacing L3, the third spacing L3 is not equal to the fifth spacing L5, and the second spacing L2 is not equal to the fourth spacing L4, and the fourth spacing L4 is not equal to the sixth spacing L6. Under this scheme, the offsets of different color pixels in the same column in the first direction X are different, and the offset relationships between different color pixels in another column are also unequal. This more complex offset pattern causes a more subtle perturbation in the relative positions of the first color pixel PX1, the second color pixel PX2, and the third color pixel PX3, more fully dispersing the periodicity of the pixel arrangement macroscopically. Each spacing L1 to L6 is independently selected from multiple different values ​​between 0 micrometers and 10 micrometers.

[0041] In Example 4, the first spacing L1 is equal to the third spacing L3 and the fifth spacing L5, while the second spacing L2 is not equal to the fourth spacing L4, and the fourth spacing L4 is not equal to the sixth spacing L6. This means that the color pixels of the j-th column pixel unit PX have the same offset between adjacent rows, exhibiting a uniform offset characteristic, while the different color pixels of the (j+1)-th column pixel unit PX have different offsets between adjacent rows, exhibiting a dispersed offset characteristic. In a specific example, the first spacing L1, the third spacing L3, and the fifth spacing L5 are set to 0, while at least one of the second spacing L2, the fourth spacing L4, and the sixth spacing L6 is not 0. In this case, the pixel unit PX in the j-th column remains aligned in the first direction X between adjacent rows, and at least one color pixel in the (j+1)-th column PX is offset in the first direction X. In other examples, the first spacing L1, the third spacing L3, and the fifth spacing L5 are all set to non-zero, causing the pixel unit PX in the j-th column to be offset as a whole in the first direction X between adjacent rows, while the pixel unit PX in the (j+1)-th column performs fine modulation on the first color pixel PX1, the second color pixel PX2, and the third color pixel PX3 respectively. Through this combination of unified offset columns and dispersed offset columns, the non-periodicity of pixel arrangement is increased while controlling visual differences. The values ​​of the first spacing L1 to the sixth spacing L6 range from 0 micrometers to 10 micrometers.

[0042] In Example 5, the first spacing L1 is not equal to the third spacing L3, the third spacing L3 is not equal to the fifth spacing L5, while the second spacing L2 is equal to the fourth spacing L4 and the sixth spacing L6. At this time, the offsets of different color pixels in the j-th column are different in the first direction X, exhibiting a dispersed offset characteristic, while the offsets of each color pixel in the (j+1)-th column are the same between adjacent rows, exhibiting a uniform offset characteristic. In one specific example, only one of the first spacing L1, the third spacing L3, and the fifth spacing L5 is set to be non-zero, while the second spacing L2, the fourth spacing L4, and the sixth spacing L6 are all zero. This causes a certain color pixel in the j-th column to shift in the first direction X, while the (j+1)-th column remains aligned. In another example, the second spacing L2, the fourth spacing L4, and the sixth spacing L6 are all set to be non-zero, while the first spacing L1, the third spacing L3, and the fifth spacing L5 are each selected with different values. This causes the pixel unit PX in the (j+1)-th column to shift as a whole in the first direction X between adjacent rows, and the relative shifts of the first color pixel PX1, the second color pixel PX2, and the third color pixel PX3 in the j-th column PX in the first direction X to be more complex. In all the above embodiments, the specific values ​​of the first spacing L1 to the sixth spacing L6 are all set in the range of 0 micrometers to 10 micrometers.

[0043] Through the aforementioned various non-equidistant pixel arrangement schemes, whether through overall offset, inter-column difference offset, or color-related dispersion offset, the macroscopic repetition period of the pixel unit group in the first direction X is effectively lengthened or modulated. Thus, when deformation and periodic displacement inevitably occur between the multiple pixel-defining layers (BPDL) during the display panel manufacturing process, the matching degree between the deformation period and the pixel arrangement period is significantly reduced, making it difficult to meet the periodic interference conditions. Consequently, the probability and visibility of moiré patterns are significantly reduced, improving the overall viewing quality of the displayed image. It is important to emphasize that this application achieves the technical effect of reducing moiré patterns simply by introducing one or more non-zero spacing L values ​​at the pixel layout level, causing the local pixel center to shift relative to the alignment reference, without increasing the number of additional film layers or changing the existing anti-spy stacking method. Compared to solutions that increase the number of film layers or introduce complex optical stacking methods, this approach has the advantages of low cost, minimal process changes, and flexible implementation.

[0044] Furthermore, the non-equidistant pixel arrangement in this application is based on the premise that the centers of the light-emitting areas of the electroluminescent layer EL, the color filter blocks in the color filter layer CF, the openings of the first black matrix layer BM1, and the second black matrix layer BM2 remain aligned. In other words, although the macroscopic arrangement of the pixel centers breaks the complete equidistant spacing through the setting of the first spacing L1 to the sixth spacing L6, from the local viewing angle of each light path and each sub-pixel, the centers of the light-emitting areas of the electroluminescent layer EL, the color filter blocks in the color filter layer CF, the openings of the first black matrix layer BM1, and the openings of the second black matrix layer BM2 remain aligned, and the viewing angle symmetry of the privacy protection scheme is not compromised. Through the multi-layer cooperation of the first black matrix layer BM1 and the second black matrix layer BM2, the display panel can still effectively control the light from different viewing angles, achieving privacy protection from a wide viewing angle while ensuring the display quality at a normal viewing angle. Therefore, this application achieves both reduced moiré patterns and privacy protection while maintaining viewing angle symmetry.

[0045] The embodiments of this application have been described in detail above. The content of this specification should not be construed as limiting the scope of protection of this application.
