[0061] 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.

[0062] 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.

[0063] Organic light-emitting diode (OLED) panels are widely used in smartphones due to their advantages such as thinness, high contrast, high refresh rate, wide viewing angle, and wide color gamut. However, during use, there are differences in lifespan between OLEDs of different colors, leading to color shifts and shortening the panel's lifespan, thus reducing its competitiveness.

[0064] In related technologies, thin-film transistors (TFTs) are used to drive organic light-emitting diodes (OLEDs) to achieve light-emitting displays. Furthermore, driving architectures such as 2T1C, 7T1C, or 6T2C are employed to compensate for the time-varying threshold voltage of the TFTs, thereby compensating for the OLED's lifespan. However, the luminous efficiency of the OLED display device itself will still decrease over time, and this driving architecture cannot compensate for this phenomenon.

[0065] To address the aforementioned problems, this application provides a display compensation method for a display panel. For ease of description, this application first introduces the structure of the display panel. Please refer to... Figure 1 and Figure 1The display panel 1 includes a substrate 10, a light-emitting functional layer 20 and a first electrode layer 30 stacked in sequence. The first electrode layer 30 includes a plurality of first electrodes 31. The first electrodes 31 are used to drive the light-emitting functional layer 20 to emit light. The display panel 1 has a plurality of partitions FA. The first electrodes 31 between different partitions FA are insulated from each other.

[0066] The display panel 1 typically has various structural forms. This application does not limit the specific structure of the display panel 1 to which the compensation method provided in this embodiment is applied. It is sufficient that the display panel 1 has a light-emitting functional layer 20 and a first electrode layer 30, the light-emitting functional layer 20 contains multiple light-emitting structures 21, and the first electrode layer 30 includes multiple first electrodes 31 corresponding to different light-emitting structures 21. For example, the first electrode 31 is a cathode.

[0067] In some optional embodiments, the display panel 1 further includes an isolation structure 40 disposed on one side of the substrate 10, the isolation structure 40 enclosing a plurality of opening structures. The isolation structure 40 may include a first isolation portion 41 and a second isolation portion 42 sequentially disposed along a direction away from the substrate 10, the orthographic projection of the first isolation portion 41 on the substrate 10 lying within the orthographic projection of the second isolation portion 42 on the substrate 10. Due to the presence of the isolation structure 40, the fabrication of the first electrode layer 30 does not require a mask, and the fabricated first electrode layer 30 can include a plurality of first electrodes 31 corresponding to the opening structures.

[0068] Based on this, the display panel 1 can have multiple different partitions FA, and the first electrodes 31 located in different partitions FA are insulated from each other. The multiple partitions FA formed by dividing the display panel 1 can be multiple partitions FA arranged adjacent to each other, or multiple partitions FA arranged with intervals between each other. Furthermore, the multiple partitions FA can be arranged side by side in the same direction, or they can be arranged side by side in multiple directions, and this application embodiment does not limit this.

[0069] Based on the display panel provided above, please refer to Figure 3 This application provides a display compensation method, including:

[0070] S100: Obtain the usage time of the display panel and the partition information of the target electrode.

[0071] In step S100, the usage time of the display panel can be the cumulative lighting time of the display panel. In subsequent steps, the corresponding compensation value will be different depending on the usage time of the display panel.

[0072] The target electrode includes at least one first electrode. As described above, the display panel is pre-divided into multiple zones, and the first electrodes in different zones are insulated from each other. The zone where the target electrode is located is determined based on its position, i.e., the zone information corresponding to the target electrode.

[0073] Typically, after a display panel has been used for a period of time, the luminous efficiency of the light-emitting structures in different zones will decrease to varying degrees. Therefore, without display compensation, differences in brightness and chromaticity parameters will easily occur between different zones. Furthermore, the amount of compensation required for different zones will also differ. In view of this, embodiments of this application perform individual compensation for different zones to improve the overall display uniformity of the compensated display panel.

[0074] It should be noted that the number of pre-divided zones in this application embodiment is not limited. The figure illustrates 9 zones as an example, but the number of zones corresponding to the display panel is not limited to 9; it can also be other numbers, such as 3, 12, or 18. The more zones in the display panel, the more finely divided the zones, and the better the final brightness compensation effect after compensating different zones. However, as the number of zones increases, the corresponding compensation calculation workload also increases. Therefore, the number of zones in the display panel can be flexibly selected according to the actual situation.

[0075] S110: Obtain the actual display grayscale of the zone where the target electrode is located.

[0076] In step S110, when a specific image is displayed on the display panel, the actual display grayscale corresponding to the zone where the target electrode is located can be determined based on the zone information. Typically, assuming other conditions remain constant, the compensation amounts corresponding to different display grayscales are not the same. Therefore, it is necessary to determine the actual display grayscale corresponding to the zone where the target electrode is located based on the image currently displayed on the display panel, so that adaptive compensation can be applied subsequently.

[0077] S120: Determine the compensation value corresponding to the target electrode based on the usage time, zoning information, and actual display grayscale.

[0078] In step S120, the inventors of this application discovered through research that different usage times of the display panel, different partition positions of the corresponding screen, and different display gray levels of the screen can all lead to problems such as brightness decay, color deviation, and uneven display of the display panel.

[0079] Based on this, by using the obtained usage time, partition information, and actual display grayscale, the compensation value corresponding to the target electrode within a specific partition can be determined. Thus, through comprehensive analysis and processing of multiple data points such as usage time, partition information, and actual display grayscale, the obtained compensation value for the target electrode can be ensured to be more accurate, contributing to better subsequent compensation effects.

[0080] S130: Compensate the target electrode according to the compensation value.

[0081] In step S130, in some embodiments, the grayscale corresponding to the partition where the target electrode is located can be adjusted first according to the compensation value. After adjusting the grayscale, the power supply voltage of the target electrode corresponding to the adjusted grayscale can be determined according to the predetermined correspondence between the grayscale corresponding to the partition where the target electrode is located and the target electrode voltage, thereby realizing the adjustment of the power supply voltage.

[0082] Alternatively, in some embodiments, the power supply voltage difference of the target electrode corresponding to the compensation value can be determined based on the predetermined correspondence between the compensation value and the power supply voltage difference of the target electrode. Then, the power supply voltage of the target electrode is adjusted according to this difference.

[0083] The compensation method provided in this application addresses a scheme where the first electrodes in different sections are mutually insulated. Based on this, it determines the compensation value corresponding to the target electrode within a specific section by obtaining data such as the usage time of the display panel, the section information of the target electrode, and the actual grayscale of the section where the target electrode is located. The power supply voltage of the target electrode is then adjusted based on the compensation value. Since the first electrode directly drives and affects the display effect of the light-emitting layer, this design in this application achieves precise control of the display panel's display effect by adjusting the voltage corresponding to the first electrode, exhibiting high accuracy. Furthermore, it allows for flexible control of different sections within different areas of the display panel, thereby helping to improve the display uniformity of the display panel and reduce problems such as color shift.

[0084] In some embodiments, please refer to Figure 4 Step S120 includes:

[0085] S121: Obtain the compensation mapping relationship corresponding to the target electrode based on the partition information and usage duration.

[0086] In step S121, the compensation mapping relationship includes the correspondence between gray levels and compensation amounts. For example, the relationship curve between the corresponding gray levels and compensation amounts can be determined based on the current time, such as... Figure 5As shown, the relationship curve between grayscale and compensation amount at a certain moment is given. Furthermore, the storage module in the display panel can store the relationship curve between grayscale and compensation amount, so that the stored relationship curve can be directly called during compensation.

[0087] Of course, in other embodiments, a table can be used to illustrate the correspondence between grayscale and compensation amount. The storage module in the display panel can then store the corresponding table for easy retrieval during compensation. Furthermore, different partition information can correspond to different compensation mapping relationships. Similarly, different usage durations will also correspond to different compensation mapping relationships.

[0088] S122: Determine the corresponding compensation value in the compensation mapping relationship based on the actual displayed grayscale.

[0089] In step S122, for example, based on the actual displayed grayscale, the compensation value corresponding to the actual displayed grayscale can be determined from the relationship curve between grayscale and compensation amount. Then, in subsequent steps, the target electrode can be compensated according to the corresponding compensation value.

[0090] In some embodiments, the actual displayed grayscale is the average or mode of all grayscale values ​​in the partition where the target electrode is located.

[0091] A single partition can include multiple light-emitting structures, and the grayscale levels corresponding to different light-emitting structures can be the same or different. Furthermore, the actual grayscale level corresponding to a partition can be set to the average of all grayscale levels in the partition, or it can be set to the mode of all grayscale levels in the partition, to meet the actual needs of different usage scenarios or different types of display panels.

[0092] In some embodiments, the light-emitting functional layer includes multiple light-emitting structures, and the partition includes one light-emitting structure.

[0093] In this configuration, each first electrode is configured separately for each light-emitting structure, enabling each first electrode to independently control each light-emitting structure. Furthermore, only one light-emitting structure is configured within each zone. Therefore, based on the actual display grayscale corresponding to that light-emitting structure, the compensation value of the first electrode corresponding to that structure can be determined, thereby improving the light-emitting accuracy of different light-emitting structures.

[0094] Secondly, this application provides a display debugging method for a target panel. For ease of description, this application first introduces the structure of the target panel. The target panel includes a substrate, a light-emitting functional layer, and a first electrode layer stacked sequentially. The first electrode layer includes multiple first electrodes, which are used to drive the light-emitting functional layer to emit light. The target panel has multiple partitions, and the first electrodes in different partitions are insulated from each other.

[0095] The target panel mentioned in this embodiment can have the same structure as the display panel mentioned in the foregoing embodiments. Furthermore, the target panel can be a sample panel used during the fabrication of the display panel. After the target panel is fabricated, debugging experiments can be performed on the target panel to obtain the compensation amount corresponding to it under different usage states. The usage states mentioned here include, but are not limited to, usage time and display grayscale.

[0096] Since the target panel has the same structure as the display panel in the aforementioned embodiment, the compensation amounts corresponding to the target panel and the display panel should be the same or similar under the same usage conditions. Based on this, the corresponding compensation data can be input into the display panel so that it can be retrieved for display compensation during subsequent use, thereby improving the display effect and lifespan of the display panel.

[0097] In view of the target panel above, please refer to Figure 6 This application provides a debugging method, including:

[0098] S200: Divide the target panel into multiple partitions.

[0099] In step S200, the first electrodes in different sections are insulated from each other. The sections mentioned here can be divided according to the number and position of the first electrodes formed during the display panel process. For example, a single section may contain only one first electrode, which is used to drive all the light-emitting structures in the corresponding section.

[0100] Alternatively, in other embodiments, a single partition may also have multiple insulated first electrodes, and different first electrodes within a single partition may be used to drive different light-emitting structures located within that partition. This application does not impose limitations on these embodiments, as long as the first electrodes in different partitions are insulated from each other.

[0101] The embodiments of this application do not limit how the insulation between different first electrodes is achieved. Exemplarily, the target panel further includes an isolation structure disposed on one side of the substrate, the isolation structure enclosing and forming multiple opening structures. The isolation structure may include a first isolation portion and a second isolation portion sequentially disposed along a direction away from the substrate, the orthographic projection of the first isolation portion on the substrate falling within the orthographic projection of the second isolation portion on the substrate. Due to the presence of the isolation structure, the fabrication of the first electrode layer does not require a mask, and the fabricated first electrode layer can include multiple first electrodes corresponding to the opening structures. Further, the first isolation portion overlapping a portion of the first electrodes may optionally include an insulating material, or the first isolation portion may include multiple spaced sub-portions to meet the insulation requirements between different first electrodes.

[0102] It should be noted that the partitioning method of the target panel mentioned in the embodiments of this application can be consistent with the partitioning method of the display panel. For example, if the target panel is divided into 9 partitions in a 3*3 pattern, then the display panel also needs to be divided into 9 partitions in a 3*3 pattern.

[0103] S210: When the target panel displays images corresponding to multiple binding point grayscales at the first moment, obtain the first display parameters of the target partition at the multiple binding point grayscales.

[0104] In step S210, optionally, the target panel needs to have good brightness and color parameters at the first moment to ensure that subsequent adjustments can be made based on the display effect of the target panel at the first moment. Further, the first moment can be the initial stage of use of the target panel.

[0105] The target panel can be connected to an image generator, which writes the image corresponding to different grayscale levels at each binding point into the target panel, enabling the target panel to display the image at the corresponding grayscale level. These multiple binding point grayscale levels can be multiple specific grayscale levels within a grayscale range. These binding point grayscale levels can be evenly distributed or non-uniformly distributed within the grayscale range. For example, when the grayscale range includes 0-255 grayscale levels, the binding point grayscale levels can be some or all of the grayscale levels from 0 / 32 / 64 / 128 / 192 / 255. Alternatively, the binding point grayscale levels can also be other grayscale levels within the 0-255 range.

[0106] After pre-determining multiple binding point grayscales, multiple first display parameters of the target partition under multiple binding point grayscales can be obtained in the first moment. The target partition is any one of the multiple partitions, and the first display parameters may include at least one of the brightness parameters and the chromaticity parameters.

[0107] S220: When the target panel displays images corresponding to multiple binding point grayscales at the second time, obtain the second display parameters of the target partition at the multiple binding point grayscales.

[0108] In step S220, the second time step is later than the first time step. Typically, the luminous efficiency of the light-emitting structure in the display panel decreases over time. Therefore, the display effect of the target panel at the second time step is usually different from that at the first time step. Based on this, the obtained second display parameters also differ from the first display parameters. For example, there might be differences in brightness parameters or chromaticity parameters.

[0109] S230: Based on the first display parameter and the second display parameter, calculate the compensation value of the first electrode corresponding to each binding point gray level in the target partition at the second time.

[0110] In step S230, the target panel can calculate the compensation value corresponding to the first electrode based on the first display parameter and the second display parameter. Then, in subsequent steps, the first electrode in the target partition can be compensated based on the compensation value, and the changes in the display parameters of the target partition can be observed through optical measurement and other methods to determine whether the adjusted display parameters of the target partition are the same as or similar to the first display parameter.

[0111] Furthermore, if the adjusted display parameters are similar to or the same as the first display parameters, the corresponding compensation value can be stored and recorded. If the adjusted display parameters still differ significantly from the first display parameters, the voltage corresponding to the first electrode can be further adjusted to make the displayed parameters the same as the first display parameters, and then the final adjusted compensation value can be stored and recorded.

[0112] In this embodiment, for a target partition, the compensation value of the corresponding first electrode is obtained by acquiring the display parameters of the target partition at different times, and can be optionally stored. Furthermore, based on the debugging method provided in this embodiment, the corresponding compensation data and time data can be entered into the display panel so that the display effect of the display panel can be periodically adjusted and compensated during subsequent use.

[0113] In some embodiments, please refer to Figure 7 In step S210, the following is included:

[0114] S211: Control the target partition to display the image screen corresponding to the gray levels of multiple binding points at the first moment.

[0115] In step S211, the target panel can be connected to a specific device that can send corresponding image frames to the target panel to drive the target panel to display image frames corresponding to the gray levels of multiple binding points. This device can be an image generator, or a host computer, PC, etc.

[0116] S212: Acquire the captured image frame and obtain the first image information corresponding to the grayscale of multiple binding points through the captured image frame.

[0117] In step S212, when the target panel displays the image corresponding to the grayscale of a specific binding point, the imaging module in the device can capture the image, obtain the captured image, and then obtain the first image information corresponding to the grayscale of the binding point through the captured image. Optionally, the first image information may include at least one of luminance information and chromaticity information.

[0118] When the target panel displays images corresponding to multiple gray levels of binding points in sequence, each image can be captured to obtain the first image information corresponding to each gray level of binding point.

[0119] S213: Based on multiple first-screen information, determine the first display parameters corresponding to the target partitions in the grayscale of the binding points.

[0120] In step S213, after obtaining the first image information corresponding to each binding point grayscale, the brightness parameters and chromaticity parameters corresponding to different binding point grayscales can be obtained from multiple first image information.

[0121] Similarly, step S220 can be the same as step S210. Specifically, step S220 may include:

[0122] The target partition is displayed at the second time point, showing the image corresponding to the grayscale of multiple binding points.

[0123] The system captures the image and obtains the second image information corresponding to the grayscale of multiple binding points.

[0124] Based on multiple second-screen information, determine the second display parameters corresponding to the target partition in the grayscale of each binding point.

[0125] In some embodiments, please refer to Figure 8 Debugging methods also include:

[0126] S240: Determine the compensation mapping relationship based on the compensation value corresponding to the gray level of each binding point.

[0127] In step S240, the compensation mapping relationship includes the correspondence between gray levels and compensation amounts. For example, a correspondence table between gray levels and compensation amounts at the second time step can be established using multiple compensation values.

[0128] Then, in subsequent steps, the mapping relationship can be stored through the storage module and imported into the display panel. This allows the display panel to be adjusted and compensated periodically based on the mapping relationship when it is used later, ensuring that the display panel has a better display effect under the bound grayscale.

[0129] In some embodiments, in step S240, the compensation value is processed based on the linear interpolation algorithm to obtain the compensation mapping relationship.

[0130] In this embodiment, the compensation gray level corresponding to each gray level can be calculated using a linear interpolation algorithm, thereby obtaining the compensation value corresponding to the non-binding gray level. This simplifies the testing process for compensation values ​​corresponding to different gray levels and improves debugging efficiency. Furthermore, a curve showing the correspondence between gray levels and compensation amounts, as shown in the figure, can also be obtained.

[0131] For example, if both sides of a specific non-binding gray level include binding gray levels, the weights can be determined based on the nearest binding gray levels on both sides and the gray level difference between the gray level and the two binding gray levels, so as to calculate the compensation value of the gray level based on the compensation value corresponding to the two binding gray levels and the corresponding weights.

[0132] In some embodiments, please refer to Figure 9 Before step S220, the following are also included:

[0133] S250: Determine multiple target times between the first time and the second time.

[0134] In step S250, multiple target times can be determined based on the time interval between the first time and the second time. Each target time is later than the first time and earlier than the second time. The time interval between any two adjacent target times can be the same or different; this embodiment does not impose any restrictions on this.

[0135] S260: Obtain the third display parameter corresponding to the grayscale of multiple binding points for the target partition at each target time.

[0136] In step S260, the display effect of the target partition at a specific grayscale level varies depending on the target time. Furthermore, there are also differences between different third display parameters corresponding to different target times. For example, these differences might lie in the brightness parameter or the chromaticity parameter.

[0137] Optionally, step S260 may include:

[0138] The image corresponding to the grayscale of multiple bound points is obtained for the target partition at the target time.

[0139] The system captures the image and obtains the third-view information corresponding to the grayscale of multiple binding points.

[0140] Based on multiple third-view information, determine the third display parameters corresponding to the target partition in the grayscale of each binding point.

[0141] S270: Based on the third display parameter and the first display parameter, determine the compensation value of the first electrode corresponding to each binding point gray level of the target partition at each target time.

[0142] In step S270, the target panel can calculate the compensation value corresponding to each bound gray level of the first electrode at the target time based on the first display parameter and the third display parameter. Then, in subsequent steps, the first electrode in the target partition can be compensated based on the compensation value, and the change of the display parameter of the target partition can be observed by means of optical measurement, etc., to determine whether the display parameter of the adjusted target partition is the same as or similar to the first display parameter.

[0143] In this embodiment, compensation values ​​corresponding to multiple target times are adjusted and subsequently stored in the display panel. This allows the display panel to adjust for different times during use, ensuring consistent and reliable display performance over long-term use.

[0144] In some embodiments, the time interval between adjacent target times gradually increases from the first time point to the second time point. For example, there is a 30-day interval between the first time point and the second time point, and the target times can be set to one target time every hour on the first day, with each subsequent time point being tested once.

[0145] In some embodiments, in step S210, first display parameters of multiple target partitions at a first time moment are simultaneously acquired. In step S220, second display parameters of multiple target partitions at a second time moment are simultaneously acquired. In step S230, compensation values ​​of the first electrodes in the multiple target partitions are simultaneously calculated.

[0146] In this embodiment, multiple target partitions can be measured simultaneously, allowing each target partition to undergo steps S210 to S230 to calculate the corresponding compensation values, thereby improving debugging efficiency. Furthermore, by storing the compensation values ​​corresponding to different target partitions in the display panel, the display effect of different partitions can be adjusted during display panel use, improving the display uniformity of the display panel.
