[0044] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0046] In organic light-emitting display devices, organic light-emitting materials are typically used to achieve the light-emitting display effect. However, different colors of organic light-emitting materials have different light emission decay rates during use. That is, as the usage time increases, different colors of organic light-emitting materials change to different degrees, which leads to problems such as color deviation in organic light-emitting display devices.

[0047] To resolve the above issues, please refer to Figure 1 and Figure 2 This application provides a pixel arrangement structure, including a plurality of repeating units 1 arranged in a repeating manner. Each repeating unit 1 includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13 with different emission colors. In addition, the repeating unit 1 also includes a preset emission sub-pixel 14. The emission color of the preset emission sub-pixel 14 is the same as that of the third sub-pixel 13. At least some of the preset emission sub-pixels 14 are configured to emit light when the wavelength of the light emitted by the third sub-pixel 13 is outside the preset wavelength range.

[0048] The pixel arrangement structure includes multiple repeating units 1, which can be arranged sequentially along a first direction X and a second direction Y. There are various ways to arrange the first direction X and the second direction Y; they can intersect at any preset angle. In some optional embodiments, the angle between the first direction X and the second direction Y is 90 degrees. Furthermore, the first direction X and the second direction Y can be the long side direction and the short side direction of the display device, respectively, or they can form a preset angle with either the long side direction or the short side direction; this application does not limit this.

[0049] Each repeating unit 1 includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13, each emitting a different color. For example, the first sub-pixel 11 emits red light, the second sub-pixel 12 emits green light, and the third sub-pixel 13 emits blue light. When the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 emit light simultaneously, the three colors mix, enabling the repeating unit 1 to emit white light. It should be noted that each repeating unit 1 may also include sub-pixels of other colors; this embodiment does not limit this.

[0050] The structural shapes of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are not limited in the embodiments of this application. Figure 1 The shape outline of a single repeating unit 1 is indicated by a dashed quadrilateral. The first sub-pixel 11 and the second sub-pixel 12 are both triangular in shape, and the third sub-pixel 13 is rectangular in shape. Figure 1 The quadrilateral formed by the dotted lines and the shape of each sub-pixel shown do not constitute a limitation on the outline shape of the repeating unit 1 and the shape of each sub-pixel in the embodiments of this application.

[0051] In addition to the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, the pixel arrangement structure also includes a preset light-emitting sub-pixel 14. The light emission color of the preset light-emitting sub-pixel 14 is the same as that of the third sub-pixel 13. At least some of the preset light-emitting sub-pixels 14 are configured to emit light when the wavelength of the light emitted by the third sub-pixel 13 is outside the preset wavelength range. The preset light-emitting sub-pixels 14 are used to adjust the color shift problem caused by the third sub-pixel 13 in the display device.

[0052] Specifically, when the display device is first used, the preset light-emitting sub-pixel 14 does not emit light. The repeating unit 1 relies on the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 to emit light together and display a specific color light emission effect. However, over time, the characteristics of the organic light-emitting material in the third sub-pixel 13 change, causing the color and corresponding wavelength of the light emitted by the third sub-pixel 13 to change, resulting in a color shift problem in the display device. At this time, because the wavelength of the light emitted by the third sub-pixel 13 has changed, the wavelength of the light emitted by the third sub-pixel 13 is outside the preset wavelength range. This causes at least some of the preset light-emitting sub-pixels 14 in the repeating unit 1 to emit light. The light emitted by the preset light-emitting sub-pixels 14 and the light emitted by the third sub-pixel 13 mix to form mixed light. The mixed light is within the preset wavelength range, thereby mitigating the color shift problem of the display device and improving display accuracy and human visual perception.

[0053] It should be noted that the "preset wavelength range" mentioned in this application embodiment refers to the fact that within the preset wavelength range, the light emitted by the third sub-pixel 13 will not cause color shift problems in the display device, or will only cause slight color shift problems. As for the value of the preset wavelength range, it needs to be determined based on factors such as the emission color of the third sub-pixel 13 and the specific pixel arrangement structure, and this application embodiment does not impose any restrictions.

[0054] Furthermore, a single repeating unit 1 may include only one preset light-emitting sub-pixel 14 or multiple preset light-emitting sub-pixels 14. When a single repeating unit 1 includes multiple preset light-emitting sub-pixels 14, the preset light-emitting sub-pixels 14 will emit light sequentially as the display device is used. Specifically, when the wavelength of the light emitted by the third sub-pixel 13 is outside the preset wavelength range, some of the multiple preset light-emitting sub-pixels 14 emit light. Then, as the usage time increases, the characteristics of the organic light-emitting material in this portion of the preset light-emitting sub-pixels 14 will also change, resulting in the wavelength of the mixed light formed by the third sub-pixel 13 and the preset light-emitting sub-pixels 14 being outside the preset wavelength range. At this time, the other preset light-emitting sub-pixels 14 emit light, thereby further alleviating the color shift problem of the display device. For example, a single repeating unit 1 includes three preset light-emitting sub-pixels 14.

[0055] Regarding the relative position of the preset luminous sub-pixel 14 with respect to the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, this application embodiment does not impose any limitations. Optionally, the preset luminous sub-pixel 14 is located on the same side of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13. Furthermore, in addition to including the preset luminous sub-pixel 14 with the same luminous color as the third sub-pixel 13, the repeating unit 1 may also include a preset luminous sub-pixel with the same luminous color as the first sub-pixel 11 or the second sub-pixel 12. This application embodiment does not impose any limitations on this.

[0056] In summary, the pixel arrangement structure provided in this application embodiment, by setting a preset light-emitting sub-pixel 14 and allowing the preset light-emitting sub-pixel 14 to emit light under specific conditions, alleviates the display color shift problem caused by the third sub-pixel 13, improves the display accuracy of the display device under long-term use, improves the visual effect for the human eye, and extends the service life of the display device.

[0057] In some embodiments, please refer to Figures 3 to 6 The preset light-emitting sub-pixel 14 and the third sub-pixel 13 together surround and form a receiving space A, and the first sub-pixel 11 and the second sub-pixel 12 are both located in the receiving space A.

[0058] The third sub-pixel 13 and the preset luminous sub-pixel 14 surround the first sub-pixel 11 and the second sub-pixel 12, for example, as shown in the image. Figure 3 and Figure 4 As shown, the third sub-pixel 13 and the preset luminous sub-pixel 14 both have an L-shaped structure and together enclose the accommodating space A. Alternatively, as... Figure 5 and Figure 6 As shown, there are three preset light-emitting sub-pixels 14. The three preset light-emitting sub-pixels 14 and the third sub-pixel 13 surround and form a rectangular accommodating space A. The edges of the first sub-pixel 11 and the second sub-pixel 12 facing the third sub-pixel 13 or the preset light-emitting sub-pixel 14 are parallel to one side of the rectangular structure.

[0059] It should be noted that in different repeating units 1 in this application embodiment, the relative positions of the third sub-pixel 13 and the preset light-emitting sub-pixel 14 may be the same or different. This application embodiment does not impose any restrictions, as long as the third sub-pixel 13 and the preset light-emitting sub-pixel 14 in a single repeating unit 1 can form an accommodating space A surrounding the first sub-pixel 11 and the second sub-pixel 12.

[0060] In this embodiment, since the third sub-pixel 13 and the preset light-emitting sub-pixel 14 surround the first sub-pixel 11 and the second sub-pixel 12, this design can improve the light emission effect when the preset light-emitting sub-pixel 14 is not emitting light. Specifically, if there are multiple preset light-emitting sub-pixels 14, and they are arranged side by side on the same side of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, when the preset light-emitting sub-pixels 14 are not emitting light, a large proportion of single non-light-emitting areas will appear in the repeating unit 1. However, when multiple preset sub-pixels are distributed around the outer periphery of the first sub-pixel 11 and the second sub-pixel, the single non-light-emitting area can be distributed into multiple small-sized non-light-emitting areas, thereby improving the display effect.

[0061] In some embodiments, such as Figure 3 and Figure 4 As shown, in different repeating units 1, the third sub-pixel 13 is located on the same side of the accommodating space A.

[0062] In this embodiment, since the positions of the third sub-pixel 13 in each repeating unit 1 are consistent, it can be ensured that the relative positions of the light emission of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 remain the same. Thus, when the preset light-emitting sub-pixel 14 does not emit light, the relative positions of the light-emitting centers in each repeating unit 1 remain consistent, thereby ensuring a better display effect.

[0063] In some embodiments, such as Figure 3 and Figure 4 As shown, in different repeating units 1, the preset light-emitting sub-pixels 14 are located on the same side of the accommodating space A.

[0064] Similar to the aforementioned embodiments, since the positions of the preset light-emitting sub-pixels 14 in each repeating unit 1 are consistent, it can be ensured that the relative positions of the light-emitting centers in each repeating unit 1 remain consistent when the preset light-emitting sub-pixels 14 are emitting light, thereby guaranteeing a superior display effect. Furthermore, as the display device is used for an extended period, the preset light-emitting sub-pixels 14 at the same positions in each repeating unit 1 can be sequentially made to emit light, thereby further improving the display effect of the display device.

[0065] In some embodiments, such as Figure 5 and Figure 6 As shown, there are multiple preset light-emitting sub-pixels 14, and at least some of the preset light-emitting sub-pixels 14 are symmetrically distributed with the third sub-pixel 13.

[0066] This design allows at least some of the preset light-emitting sub-pixels 14 to be positioned relative to the third sub-pixel 13 about a specific axis, simplifying the structural design of the preset light-emitting sub-pixels 14 and the arrangement of the preset light-emitting sub-pixels 14 and the third sub-pixel 13 around the first sub-pixel 11 and the second sub-pixel 12. This reduces the fabrication difficulty of each repeating unit 1 in the display device. Optionally, at least some of the preset light-emitting sub-pixels 14 and the third sub-pixel 13 are centrally symmetrically arranged.

[0067] In some embodiments, such as Figures 5 to 7 As shown, the third sub-pixel 13 is located on one side of the accommodating space A in the first direction X, and a plurality of preset luminous sub-pixels 14 include a first preset sub-pixel 141 located in the first direction X in the accommodating space A away from the third sub-pixel 13. In at least partially adjacent repeating units 1, the third sub-pixel 13 of one and the first preset sub-pixel 141 of the other are located between two accommodating spaces A.

[0068] As described above, some adjacent repeating units 1 are arranged side by side in the first direction X. Therefore, the two accommodating spaces A in some adjacent repeating units 1 are arranged side by side in the first direction X. Based on this, the embodiments of this application further arrange the third sub-pixel 13 and the first preset sub-pixel 141 in a single repeating unit 1 on both sides of the accommodating space A in the first direction X, so that in two adjacent repeating units 1 in the first direction X, the third sub-pixel 13 of one and the first preset sub-pixel 141 of the other are located between the two accommodating spaces A. In addition, since the third sub-pixel 13 and the first preset sub-pixel 141 emit the same color, the light-emitting layers 22 of the third sub-pixel 13 and the first preset sub-pixel 141 can be formed using the same mask opening during the manufacturing process of the display device, thereby simplifying the manufacturing process.

[0069] It should be noted that both the third sub-pixel 13 and the first preset sub-pixel 141 include a cathode 23, an anode 21, and a light-emitting layer 22. The cathode 23 is a shared film layer, and the third sub-pixel 13 and the first preset sub-pixel 141 can use the same mask opening to form the light-emitting layer 22; that is, the third sub-pixel 13 and the first preset sub-pixel 141 can share the same light-emitting layer 22. However, the anode 21 in the third sub-pixel 13 and the first preset sub-pixel 141 need to be formed using different mask openings; that is, the anode 21 of the third sub-pixel 13 and the anode 21 of the first preset sub-pixel 141 are two separate structures.

[0070] In this design, the anode 21 of the third sub-pixel 13 and the anode 21 of the first preset sub-pixel 141 can control only a portion of the structure in the light-emitting layer 22 to emit light or turn off. Specifically, when the third sub-pixel 13 needs to emit light while the first preset sub-pixel 141 does not, only the anode 21 of the third sub-pixel 13 can be used for driving control, so that the portion of the light-emitting layer 22 shared by the third sub-pixel 13 and the first preset sub-pixel 141 emits light, while the portion corresponding to the first preset sub-pixel 141 does not emit light. When both the third sub-pixel 13 and the first preset sub-pixel 141 need to emit light, the anode 21 of the third sub-pixel 13 and the anode 21 of the first preset sub-pixel 141 are driven for joint control, so that the light-emitting layer 22 shared by the third sub-pixel 13 and the first preset sub-pixel 141 emits light completely.

[0071] In some embodiments, the third sub-pixel 13 includes a first edge L1 that is away from the accommodating space A, and the first preset sub-pixel 141 includes a second edge L2 that is away from the accommodating space A, the second edge L2 being parallel to the first edge L1.

[0072] The positions of the third sub-pixel 13 and the first preset sub-pixel 141 mentioned in the embodiments of this application specifically refer to the positions of the anode 21 in the third sub-pixel 13 and the anode 21 in the first preset sub-pixel 141, which will not be described again in the embodiments of this application.

[0073] The third sub-pixel 13 has a first edge L1, and the first preset sub-pixel 141 has a second edge L2, with the first edge L1 and the second edge L2 being parallel. This design can effectively utilize the space between two adjacent accommodating spaces A in the first direction X, allowing the third sub-pixel 13 in one of the partially adjacent repeating units 1 to be arranged more closely with the first preset sub-pixel 141 in the other, thereby reducing the distance between adjacent repeating units 1, increasing pixel density, and thus improving the resolution of the display device.

[0074] In some embodiments, in the same repeating unit 1, the third sub-pixel 13 and the first preset sub-pixel 141 are centrally symmetrically arranged. Exemplarily, the shapes of the third sub-pixel 13 and the first preset sub-pixel 141 can be isosceles trapezoids.

[0075] In some embodiments, such as Figure 5 and Figure 6 As shown, the plurality of preset light-emitting sub-pixels 14 also include a second preset sub-pixel 142 and a third preset sub-pixel 143 located on both sides of the accommodating space A in the second direction Y. In at least some of the adjacent repeating units 1, the second preset sub-pixel 142 of one unit and the third preset sub-pixel 143 of the other unit are located between two accommodating spaces A.

[0076] In addition to being arranged side-by-side along the first direction X, multiple repeating units 1 are also arranged side-by-side along the second direction Y. Similar to the first preset sub-pixel 141 and the third sub-pixel 13, in this embodiment, the second preset sub-pixel 142 and the third preset sub-pixel 143 in a single repeating unit 1 are respectively disposed on both sides of the accommodating space A in the second direction Y, so that in two adjacent repeating units 1 in the second direction Y, the second preset sub-pixel 142 of one and the third preset sub-pixel 143 of the other are located between the two accommodating spaces A. Furthermore, since the second preset sub-pixel 142 and the third preset sub-pixel 143 emit the same color, during the manufacturing process of the display device, the light-emitting layers of the second preset sub-pixel 142 and the third preset sub-pixel 143 in two adjacent repeating units 1 in the second direction Y can be formed using the same mask opening, thereby simplifying the manufacturing process.

[0077] It should be noted that the anodes in the second preset sub-pixel 142 and the third preset sub-pixel 143 need to be formed using different mask openings, that is, the anodes of the second preset sub-pixel 142 and the anodes of the third preset sub-pixel 143 are two separate structures.

[0078] In some embodiments, the second preset sub-pixel 142 includes a third edge L3 facing away from the accommodating space A, and the third preset sub-pixel 143 includes a fourth edge L4 facing away from the accommodating space A, with the third edge L3 parallel to the fourth edge L4. This design can effectively utilize the space between two adjacent accommodating spaces A in the second direction Y, allowing the second preset sub-pixel 142 in one of the partially adjacent repeating units 1 to be arranged more closely with the third preset sub-pixel 143 in the other, thereby reducing the distance between adjacent repeating units 1, increasing pixel density, and thus improving the resolution of the display device.

[0079] In some embodiments, at least one of the second preset sub-pixel 142 and the third preset sub-pixel 143 is symmetrically distributed with respect to the third sub-pixel 13. Further, optionally, both the second preset sub-pixel 142 and the third preset sub-pixel 143 are symmetrically arranged with respect to the third sub-pixel 13.

[0080] In some embodiments, the light emission attenuation rate of the third sub-pixel 13 is greater than the light emission attenuation rate of the first sub-pixel 11 and / or the second sub-pixel 12.

[0081] The rate of light emission decay depends on the corresponding luminescent material. For different luminescent materials, some luminescent materials exhibit a greater rate of characteristic change with increasing usage time than others, resulting in a decay of the emitted color and causing color shift issues. In summary, the "light emission decay rate" mentioned in the embodiments of this application refers to the rate of characteristic change of the corresponding luminescent material.

[0082] Because the light emission attenuation rate of the third sub-pixel 13 is greater than that of the first sub-pixel 11 and / or the second sub-pixel 12, the third sub-pixel 13 is more prone to color shift problems compared to the first sub-pixel 11 and the second sub-pixel 12, resulting in a decrease in the display accuracy of the display device. Based on this, this embodiment sets the emission color of the preset light-emitting sub-pixel 14 to be the same as the emission color of the third sub-pixel 13, thereby enabling the preset light-emitting sub-pixel 14 to compensate for the light emitted by the third sub-pixel 13, thus alleviating the color shift problem of the display core device.

[0083] In some embodiments, the emission color of the third sub-pixel 13 is blue. Compared to other colors, blue pixels are more prone to color shift, resulting in a yellowish display. Therefore, in this embodiment, the emission color of the preset emission sub-pixel 14 is set to blue to compensate for the blue light.

[0084] In some embodiments, the outer contours of the first sub-pixel 11 and the second sub-pixel 12 are the same as the inner wall contour of the accommodating space A. Based on the outer contour shapes of the first sub-pixel 11 and the second sub-pixel 12, the contour shapes of the third sub-pixel 13 and the preset light-emitting sub-pixel 14 are designed to match their shapes and sizes, thereby optimizing the structure of the repeating unit 1 and making the pixel layout within the repeating unit 1 more compact, which is beneficial for improving the resolution of the display device.

[0085] Secondly, such as Figure 8 As shown, this application provides a display device including the pixel arrangement structure of any of the foregoing embodiments.

[0086] It should be noted that the display device provided in this application embodiment has the beneficial effects of the pixel arrangement structure in any of the foregoing embodiments. For the effects of the display panel, please refer to the foregoing description of the pixel arrangement structure. This application embodiment will not repeat the description.

[0087] Thirdly, such as Figure 9 As shown, this application provides a color shift compensation method, applied to the display device in any of the foregoing embodiments. The color shift compensation method includes:

[0088] S100: Obtain the first color deviation value of the image displayed by the display device.

[0089] In step S100, the display device is the display device in any of the foregoing embodiments, and the specific details can be found in the foregoing description of the display device; these details will not be repeated in the embodiments of this application. As the display device is used, the color shift phenomenon gradually intensifies, and the accuracy of the image displayed by the display device gradually decreases. During this process, the display device can detect the first color shift value of the image displayed by the display device in real time or under specific conditions.

[0090] When the first color deviation value is within the preset color deviation threshold range, it indicates that the color deviation problem of the display device has a relatively minor impact on the displayed image. When the first color deviation value is greater than the preset color deviation threshold, it indicates that the color deviation problem of the display device is more serious, and at this time, some color deviation compensation is required.

[0091] S110: When the first color deviation value is greater than the preset color deviation threshold, control at least some preset light-emitting sub-pixels to emit light.

[0092] In step S110, when the color shift problem has a significant impact on the displayed image, the display device can control one or more preset light-emitting sub-pixels to emit light, thereby alleviating the color shift problem caused by the third sub-pixel, improving the display accuracy of the display device under long-term use, improving the visual effect for the human eye, and extending the service life of the display device.

[0093] It should be noted that in this embodiment, the emission color of the preset luminous sub-pixel is the same as the emission color of the third sub-pixel, so as to achieve a color shift compensation effect on the light emitted by the third sub-pixel. Furthermore, a preset luminous sub-pixel with the same emission color as the first or second sub-pixel can also be provided to achieve a color shift compensation effect on the light emitted by the first and / or second sub-pixel; this embodiment does not impose any limitations on this.

[0094] In some embodiments, in different repeating units, the third sub-pixel is located on the same side of the accommodating space, and the number of preset luminous sub-pixels is multiple. In step S110, the preset luminous sub-pixels at the same position in different repeating units are controlled to emit light.

[0095] Since the positions of the third sub-pixels in each repeating unit are consistent, it can be ensured that the relative positions of the light emission of the first, second, and third sub-pixels remain the same. Thus, even when the preset light-emitting sub-pixels do not emit light, the relative positions of the light-emitting centers in each repeating unit remain consistent, thereby ensuring a better display effect.

[0096] Building upon this, the embodiments of this application further control the emission of preset light-emitting sub-pixels at the same position in different repeating units when a color shift problem occurs in the display device. This ensures that the relative positions of the light-emitting centers in each repeating unit remain consistent when the preset light-emitting sub-pixels are emitting light, further guaranteeing a superior display effect.

Those skilled in the art will clearly understand that, for the sake of convenience and brevity, substitutions for other connection methods described above can be made by referring to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the scope of protection of this application is not limited thereto.
