[0041] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0042] For an OLED display panel, Mura is an inevitable defect. Mura is the Romanized spelling of the Japanese Chinese character "斑" (spot), which originally means unevenness and flaws. Compensating the display panel can eliminate Mura and make the display image more uniform.

[0043] In the process of implementing the present invention, the inventors found the following problems in the related art. At present, the optimization effect of compensating the Mura area of the display panel is evaluated by the method of manual visual inspection. This evaluation method is based on personal experience and judgment criteria, and is easily affected by environmental factors such as external light. Therefore, there are certain deviations in the evaluation results, and improvement is urgently needed.

[0044] The following further describes the specific implementation of the embodiments of the present application with reference to the accompanying drawings of the embodiments of the present application.

[0045] Please refer to Figure 1 , which shows a flowchart of the steps of a display data processing method according to an embodiment of the present application.

[0046] The display data processing method of this embodiment includes the following steps:

[0047] Step S102: Based on the display data of the first display panel and the first initial compensation data, compensate the first display panel to obtain a first compensation data set and the recognizable difference of the first display panel before and after compensation.

[0048] The display panel is a key part of the display, which can convert digital signals into visible images. In the embodiments of the present application, the first display panel refers to one of the display panels obtained after a whole OLED display substrate is cut. In the production process of OLED, first, a TFT (Thin Film Transistor) substrate is fabricated, which is the main step of the backplane process. Subsequently, various layers of materials are deposited on the TFT substrate through processes such as evaporation, coating, exposure, and etching to form a complete OLED structure. After these steps are completed, the obtained is the OLED substrate to be cut, and then the OLED substrate to be cut is cut into multiple small-sized display panels to meet the product requirements of different sizes and specifications.

[0049] OLED display technology has the characteristic of self-luminescence. Since each pixel in the OLED display panel acts as its own emitter, the inconsistency between pixels is inevitable, resulting in Mura defects. Therefore, targeted compensation is required.

[0050] Among them, the display data is brightness data and / or chromaticity data; when the display data is brightness data, brightness compensation is performed on the display panel; when the display data is chromaticity data, chromaticity compensation is performed on the display panel; when the display data includes brightness data and chromaticity data, brightness compensation and chromaticity compensation are performed on the display panel, and the order of performing brightness compensation and chromaticity compensation on the display panel is not distinguished.

[0051] In a feasible manner, an optical extraction method can be used to perform initial compensation on the display panel, and then the display data processing of the embodiment of the present application is realized on this basis. The basic operation of the optical extraction method includes: first, the display panel to be compensated, i.e., the first display panel, is lit to display several pictures (generally grayscale images or RGB images); after the first display panel is successfully lit, a camera (generally a high-resolution and high-precision CCD camera is used, and the camera can also be selected according to the parameters of the first display panel to be photographed) is used to shoot the picture displayed by the first display panel, and the brightness data of the picture is collected; the brightness data is compensated and calculated according to the corresponding compensation algorithm to generate the corresponding compensation data, i.e., the first initial compensation data; finally, the brightness compensation of the first display panel is performed according to the compensation data, so as to obtain the first compensation data set. Among them, the above compensation algorithm can be appropriately set by those skilled in the art according to actual needs, including but not limited to a brightness compensation algorithm based on grayscale and luminous time, an adaptive brightness compensation algorithm, a linear brightness compensation algorithm, etc., and the embodiment of the present application does not limit this.

[0052] In a feasible manner, the display data of the first display panel includes the display data of each pixel in the picture of the first display panel, thereby each pixel can be analyzed. Figure 2 An exemplary schematic diagram of the principle of compensating for mura areas is shown. The display data uses brightness data. Based on the brightness data of each pixel, the overly bright or dark Mura areas are analyzed and found, and the corresponding compensation data are used to compensate respectively, so that the compensated Mura area image is more uniform.

[0053] In one feasible manner, the display data of the first display panel is compensated and calculated using a corresponding compensation algorithm, and the obtained first initial compensation data is implemented in the form of a binary file, which contains binary compensation data corresponding to each pixel. It should be noted that for the Mura-free area in the first display panel, the display conditions of the pixels contained therein are evaluated as uniform brightness and / or uniform color, so the compensation data corresponding to the pixels in the area is implemented as a null value, or the corresponding compensation data is a binary value of 0, and all compensation data of the first display panel constitute a first compensation data set.

[0054] Just Noticable Difference (JND) can be used to quantify the sensitivity and resolution of the human sensory system, representing the minimum change that a person can perceive for a particular sensory stimulus. In an embodiment of the present application, a recognizable difference (hereinafter referred to as JND) is used to indicate the limit of visual differences that the human eye can perceive. The JND value of the image can be used to evaluate the quality of the current image. For example, the larger the JND value of the image of the first display panel, the higher the limit of visual differences that the human eye can perceive, and the greater the relative difference between Mura and other areas on the current image, so it can be evaluated as the lower the quality of the image of the first display panel; on the contrary, the smaller the JND value of the image of the first display panel, the lower the limit of visual differences that the human eye can perceive, and the smaller the relative difference between Mura and other areas on the current image, so it can be evaluated as the higher the quality of the image of the first display panel. In practical applications, other feasible indicators can also be used to evaluate image quality, including but not limited to SSIM (Structure Simplicity Index), PSNR (Peak Signal-to-Noise Ratio), etc.

[0055] In one feasible method, the JND is obtained based on a model of the spatial distribution of human eye sensitivity. For example, NASA's Spatial Standard Observer (SSO) model. Based on the original image of the first display panel captured by the camera, the SSO model first performs operations such as cropping and sampling on the original image to filter out unnecessary signals in the original image; further removes the suspected Mura signal in the original image to obtain the image to be tested of the first display panel; compares the original image with the image to be tested, measures the difference between the two, and the SSO model outputs the JND of the original image of the first display panel.

[0056] Step S104: obtaining a unit compensation value for quantifying the degree of compensation based on the identifiable difference and the first compensation data set.

[0057] As mentioned above, in one example, a corresponding compensation algorithm is used to perform compensation calculation on the display data of the first display panel. The process is as follows: Figure 3 As shown by the right arrow in the left interface, the first initial compensation data obtained is implemented in the form of a binary file, which contains binary compensation data corresponding to each pixel point. All compensation data of the first display panel constitute a first compensation data set, such as Figure 3 The left side of the interface shows “offset1” and the downward arrow.

[0058] In one feasible manner, the exponential compensation value of the first compensation data corresponding to each pixel point in the first compensation data set is used to obtain a unit compensation value for quantifying the compensation degree.

[0059] The use of exponential compensation values ​​avoids the problem that the compensation values ​​between display panels are not much different when the compensation values ​​in the compensation data are evenly distributed or when individual compensation values ​​are extremely distributed, thus causing the unit compensation value to be unrepresentative.

[0060] In a preferred implementation of the first embodiment of the present application, the exponential compensation value of the first compensation data corresponding to each pixel is implemented as the square value of the first compensation data corresponding to each pixel. Based on this, in a feasible manner, the sum of the square values ​​of the first compensation data corresponding to each pixel is used to obtain the total compensation value of the first display panel. In this way, the influence of uniform distribution of compensation values ​​or extreme distribution of individual compensation values ​​on the compensation values ​​between display panels is eliminated, so that the unit compensation value of the display panel is representative.

[0061] The JND before and after the first display panel compensation reflects the image quality of the image displayed by the first display panel before and after the compensation.

[0062] In a feasible manner, the absolute value of the difference between the JNDs before and after compensation of the first display panel is obtained. The process is as follows: Figure 3 As shown by the upward arrow in the left interface, based on this, the ratio of the sum of the square values ​​of the first compensation data corresponding to each pixel point in the first compensation data set to the absolute value of the difference between the JND before and after compensation of the first display panel is obtained, thereby obtaining a unit compensation value. The process is as follows Figure 3 The calculation process is shown in the lower middle part of the left interface. Figure 3 As shown in the left interface, the absolute value JND3 of the difference between the JND before and after compensation of the first display panel is obtained, based on which the ratio of the sum of the square values ​​of the first compensation data corresponding to each pixel point in the first compensation data set offset1 to JND3 is obtained, thereby obtaining the unit compensation value JND4. The unit compensation value represents the compensation value required for a unit JND change value, thereby realizing the quantification of the compensation degree.

[0063] By obtaining the unit compensation value, the display data processing method of the embodiment of the present application realizes accurate quantification of the compensation degree. Using the unit compensation value of the first display panel, the compensation degree of other panels of the same batch as the first display panel can be accurately measured.

[0064] Step S106: Based on the display data of the second display panel and the second initial compensation data, the second display panel is compensated to obtain a second compensation data set.

[0065] In order to make the compensation degree result more accurate, the second display panel adopts the same compensation method as the first display panel. The process of compensating the second display panel is as follows: Figure 3 As shown by the right arrow in the right side of the interface.

[0066] In one feasible embodiment, the first display panel and the second display panel belong to the same display substrate or belong to different display substrates from the same production batch before being cut; wherein the first display panel and the second display panel are different parts of the same display substrate after being cut or different parts of different display substrates from the same production batch after being cut.

[0067] Step S108: obtaining a recognizable difference change value corresponding to the second display panel according to the unit compensation value and the second compensation data set.

[0068] In a feasible manner, the exponential compensation value of the second compensation data corresponding to each pixel point in the second compensation data set is used to obtain the identifiable difference change value corresponding to the second display panel.

[0069] In this embodiment, for the exponential compensation value of the second compensation data corresponding to each pixel point in the second compensation data set and the exponential compensation value of the first compensation data corresponding to each pixel point in the first compensation data set, the exponential levels of the exponential compensation values ​​of the two are also set in the same way, for example, both are in square form, or both are in cubic form, etc.

[0070] In one feasible manner, based on the ratio of the exponential compensation value of the second compensation data corresponding to each pixel point in the second compensation data set to the unit compensation value, the identifiable difference change value corresponding to the second display panel is obtained ( Figure 3 Indicated as JND change ).

[0071] Further optionally, based on the second compensation data set ( Figure 3 The ratio of the sum of the square values ​​of the second compensation data corresponding to each pixel in the display panel (indicated as "offset2") to the unit compensation value is obtained to obtain the recognizable difference change value corresponding to the second display panel. The process is as follows: Figure 3 The calculation process is shown below the right interface in FIG. In this feasible manner, the corresponding unit compensation value is obtained based on the sum of the square values ​​of the first compensation data corresponding to each pixel point in the first compensation data set. Figure 3 As shown in the right interface, based on the ratio of the sum of the square values ​​of the second compensation data corresponding to each pixel in the second compensation data set offset2 to the unit compensation value JND4, the recognizable difference change value JND corresponding to the second display panel is obtained. change .

[0072] For example, when the display data is brightness data, a brightness compensation algorithm is used to perform compensation calculation on the brightness data of the first display panel to obtain first initial brightness compensation data, and brightness compensation is performed on the first display panel based on the first initial brightness compensation data to obtain a first brightness compensation data set offset11, as well as a recognizable difference of the first display panel before and after brightness compensation; offset11 contains the first brightness compensation data of all pixels in the first display panel; the absolute value JND31 of the difference between the JNDs before and after brightness compensation of the first display panel is obtained, and based on this, the ratio of the sum of the square values ​​of the first brightness compensation data corresponding to each pixel in offset11 to JND31 is obtained, thereby obtaining a unit brightness compensation value JND41; the second display panel adopts the same brightness compensation method as the first display panel to obtain a second brightness compensation data set offset21 of the second display panel; based on the ratio of the sum of the square values ​​of the second brightness compensation data corresponding to each pixel in offset21 to JND41, the recognizable difference change value JND corresponding to the second display panel is obtained. change1 , to achieve quantification of the brightness compensation degree of the second display panel.

[0073] For another example, when the display data is chromaticity data, a chromaticity compensation algorithm is used to perform compensation calculation on the chromaticity data of the first display panel to obtain first initial chromaticity compensation data, and chromaticity compensation is performed on the first display panel based on the first initial chromaticity compensation data to obtain a first chromaticity compensation data set offset12, as well as a recognizable difference between the first display panel before and after chromaticity compensation; offset12 includes the first chromaticity compensation data of all pixels in the first display panel; the absolute value JND32 of the difference between the JNDs before and after chromaticity compensation of the first display panel is obtained, and based on this, the ratio of the sum of the square values ​​of the first chromaticity compensation data corresponding to each pixel in offset12 to JND32 is obtained, thereby obtaining a unit chromaticity compensation value JND42; the second display panel adopts the same chromaticity compensation method as the first display panel to obtain a second chromaticity compensation data set offset22 of the second display panel; based on the ratio of the sum of the square values ​​of the second chromaticity compensation data corresponding to each pixel in offset22 to JND42, the recognizable difference change value JND corresponding to the second display panel is obtained. change2 , to achieve quantification of the chromaticity compensation degree of the second display panel.

[0074] For another example, when the display data is brightness and chromaticity, the brightness compensation algorithm and the chromaticity compensation algorithm in the above embodiment are used to perform brightness compensation and chromaticity compensation respectively, and the two compensation methods are not in order, and the brightness compensation degree of the second display panel and the chromaticity compensation degree of the second display panel are quantified respectively. In other embodiments, brightness compensation and chromaticity compensation can be performed at the same time, which is not limited here.

[0075] According to the unit compensation value used to quantify the compensation degree, for the second display panel, the JND change value before and after the compensation of the second display panel can be obtained without obtaining the JND before and after the compensation of the second display panel. Based on this, the compensation degree of the second display panel is quantified. Compared with the evaluation method of human visual observation, the quantified value is not affected by human subjective feelings, which improves the accuracy of the compensation degree evaluation, is more efficient, and reduces labor costs.

[0076] Based on the above display data processing method, in a feasible solution, the display data processing method of the embodiment of the present application further includes:

[0077] The compensation degree of the second display panel is obtained according to the identifiable difference change value corresponding to the second display panel and the preset corresponding rule; wherein the preset corresponding rule includes the corresponding rule between different identifiable difference change values ​​corresponding to the second display panel and different compensation degrees. According to the preset corresponding rule, the compensation degree of the second display panel can be quickly obtained, thereby improving processing efficiency.

[0078] The preset corresponding rule can correspond different recognizable difference change values ​​corresponding to the second display panel to different compensation degrees, and different compensation degrees can be obtained according to different recognizable difference change values.

[0079] In one feasible manner, the preset corresponding rule indicates the proportional relationship between different recognizable difference change values ​​corresponding to the second display panel and different compensation degrees. According to the preset rule, the changing trend of the compensation degree is the same as the changing trend of the recognizable difference change value, so that the changing trend of the compensation degree of the second display panel can be obtained more quickly based on the changing trend of the compensation degree. For example, the larger the recognizable difference change value corresponding to the second display panel, the higher the compensation degree. In practical applications, the preset corresponding rule can also be implemented as other feasible corresponding relationships. For example, the recognizable difference change value corresponding to the second display panel is divided into three categories of intervals, and the three categories of intervals correspond to three different compensation degrees of "poor", "good" and "excellent", respectively.

[0080] It can be seen that, through the scheme of the embodiment of the present application, based on the display data of the first display panel and the first initial compensation data, the first compensation data set of the display panel is obtained; and then the compensation value of the unit recognizable difference value is obtained in combination with the recognizable difference value of the first display panel before and after compensation, that is, the unit compensation value, which can accurately quantify the compensation degree of the compensation. In addition, the unit compensation value can also be used to accurately measure the compensation effect of the subsequent compensation of other panels of the same batch as the first display panel (obtained after the display substrate of the same batch is cut). Based on the compensation value of the improved unit JND value, the change of the JND of the second display panel can be obtained when the compensation value of the second display panel is known, so as to know the compensation degree of the compensation of the second display panel, which is more accurate than the evaluation method of human visual observation, eliminates the influence of subjective factors of the tester, and reduces the labor cost; at the same time, the exponential compensation value of the compensation data can be used to avoid the problem of lack of representativeness of the compensation data caused by uniform distribution of the compensation data in the compensation data set, or extreme distribution of individual compensation data, so that the display data processing result is more accurate.

[0081] Based on the above embodiments, Figure 4 , shows another display data processing method according to an embodiment of the present application, which optimizes part of the process in the aforementioned embodiment to further improve the accuracy of the display data processing results.

[0082] The display data processing method of this embodiment includes the following steps:

[0083] Step S202: Based on the display data of the first display panel and the first initial compensation data, the first display panel is compensated to obtain a first compensation data set and a recognizable difference between the first display panel before and after the compensation.

[0084] The specific implementation of step S202 may refer to the implementation of step S102 in the embodiment, which will not be described in detail here.

[0085] In this embodiment, the first display panel exists on a whole display substrate before being cut. For display substrates of the same production batch, part of the multiple display panels after being cut is randomly selected as a control group. For example, one tenth of the multiple display panels after being cut is selected as a control group, which is used as a quantitative basis for the remaining nine tenths. After the process of step S202, multiple first compensation data sets and recognizable differences between multiple first display panels before and after compensation are obtained. It should be noted that the acquisition of the first compensation data set and the recognizable differences between the first display panels before and after compensation can be implemented with reference to the description of the relevant parts in Example 1, and will not be repeated here. It should be noted that the above examples are only for illustration and are not for limitation. In actual applications, the selection of the control group can be determined based on the number of display substrates and the number of display panels after cutting, etc., and the embodiments of the present application do not limit this.

[0086] Step S204: obtaining a unit compensation value representative value for quantifying the degree of compensation based on the identifiable difference and the first compensation data set.

[0087] In one feasible manner, the exponential compensation value of the first compensation data corresponding to each pixel point in the first compensation data set is used to obtain a unit compensation value representative value for quantifying the compensation degree.

[0088] The exponent of the exponential compensation value of the first compensation data corresponding to each pixel point in the first compensation data set includes multiple preset values, such as 2, 4, 6, etc.

[0089] The step of obtaining the unit compensation value may refer to step S104 in the first embodiment, and will not be described in detail here.

[0090] Based on the unit compensation value of each display panel in the control group, a representative value of the unit compensation value is obtained. The representative value of the unit compensation value is a representative value of the unit compensation values ​​of all display panels in the control group, which can reflect the average level of the unit compensation value of each display panel in the control group. In a feasible manner, the average value of the unit compensation value of each display panel in the control group is obtained to obtain the representative value of the unit compensation value. It should be noted that the above example is for illustration only and is not intended to be limiting. In actual applications, the representative value of the unit compensation value can also be obtained, for example, by calculating the median of the unit compensation values ​​of all display panels in the control group, and the embodiments of the present application are not limited to this.

[0091] Step S206: Based on the display data of the second display panel and the second initial compensation data, the second display panel is compensated to obtain a second compensation data set.

[0092] To control the variables, the second display panel adopts a compensation method corresponding to that of the first display panel, for example, an external compensation method of optical extraction.

[0093] In one feasible embodiment, the first display panel and the second display panel belong to the same display substrate or belong to different display substrates from the same production batch before being cut; wherein the first display panel and the second display panel are different parts of the same display substrate after being cut or different parts of different display substrates from the same production batch after being cut.

[0094] Step S208: Obtaining a recognizable difference change value corresponding to the second display panel according to the unit compensation value representative value and the second compensation data set.

[0095] In a feasible manner, the exponential compensation value of the second compensation data corresponding to each pixel point in the second compensation data set is used to obtain the identifiable difference change value corresponding to the second display panel.

[0096] In this embodiment, for the exponential compensation value of the second compensation data corresponding to each pixel in the second compensation data set and the exponential compensation value of the first compensation data corresponding to each pixel in the first compensation data set, the exponential levels of the exponential compensation values ​​of the two are set correspondingly. For example, if the exponential compensation value of the first compensation data corresponding to each pixel in the first compensation data set is the square value of the first compensation data corresponding to each pixel, then the exponential compensation value of the second compensation data corresponding to each pixel in the second compensation data set is the square value of the second compensation data corresponding to each pixel.

[0097] In this embodiment, the recognizable difference change value corresponding to the second display panel is obtained based on the ratio of the exponential compensation value of the second compensation data corresponding to each pixel point in the second compensation data set to the unit compensation value representative value. In a feasible manner, the recognizable difference change value corresponding to the second display panel is obtained based on the ratio of the sum of the square values ​​of the second compensation data corresponding to each pixel point in the second compensation data set to the unit compensation value representative value. In this feasible manner, correspondingly, the unit compensation value representative value is obtained based on the sum of the square values ​​of the first compensation data corresponding to each pixel point in the first compensation data set.

[0098] Based on this, in a feasible solution, the display data processing method of the embodiment of the present application further includes:
