It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The embodiments of the present application are described in detail below.

[0028] In the related art, taking the display screen as an LED display screen as an example, during the display process, the brightness of the red, green and blue LEDs will decay as the temperature rises. In addition, the decay of the three colors is inconsistent at the same temperature, resulting in color cast when used at different temperatures, resulting in poor display effect. In order to solve the defects in the related art, the embodiment of the present application provides a display screen correction method, which is applied to an electronic device, and the electronic device includes a display screen, and can include the following steps:

[0029] During the display screen display process, determining a target temperature difference value between a first area and a plurality of neighboring areas corresponding to the first area;

[0030] determining target correction data corresponding to the target temperature difference value;

[0031] Correcting the first display parameter of the first area according to the target correction data to obtain a second display parameter;

[0032] The first area is displayed according to the second display parameter.

[0033] The display screen correction method described in the embodiment of the present application is applied to an electronic device, which includes a display screen. During the display process of the display screen, a target temperature difference value between a first area and multiple neighboring areas corresponding to the first area is determined, and target correction data corresponding to the target temperature difference value is determined. The first display parameter of the first area is corrected according to the target correction data to obtain a second display parameter, and the first area is displayed according to the second display parameter. In this way, the target temperature difference value reflects the degree of display consistency between the first area and its corresponding adjacent areas to a certain extent, and then the correction data corresponding to the display consistency degree is determined. Then, the consistency between the first area and its corresponding adjacent areas can be adjusted based on the correction data, thereby ensuring the consistency of the display effect of the display screen, helping to improve the display effect of the entire display screen, and improving the intelligence of the display correction of the display screen.

[0034] See also Figure 1 , Figure 1 1 is a flow chart of a display screen calibration method provided by an embodiment of the present application. As shown in the figure, the display screen calibration method is applied to an electronic device, wherein the electronic device includes a display screen. The display screen calibration method includes:

[0035] 101. During display on the display screen, determine a target temperature difference value between a first area and a plurality of neighboring areas corresponding to the first area.

[0036] The first area is any display area of ​​the display screen. The display screen may include multiple display areas. The sizes of the display areas may be the same or different. Each display area may correspond to a display module, or one display module may correspond to at least one display area. Each display module may exist independently, or may be integrated with other display modules.

[0037] The area of ​​each display region may be the same or different, and the shape of each display region may be the same or different.

[0038] In a specific implementation, the display screen can be used to display images or videos. The display screen may include a display panel. Among them, the display panel may adopt a flexible light-emitting diode (FLED), a mini light-emitting diode (miniled), a MicroLed, a Micro-oLed, a quantum dot light emitting diode (QLED), an organic light-emitting diode (OLED), a liquid crystal display (LCD), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), etc.

[0039] In a specific implementation, the electronic device may include one or more display screens.

[0040] In a specific implementation, during the display process on the display screen, the target temperature difference value between the first area and multiple neighboring areas corresponding to the first area can be determined. The target temperature difference value reflects, to a certain extent, the degree of display consistency between the first area and its corresponding adjacent areas. The larger the target temperature difference value, the lower the degree of consistency. Conversely, the smaller the target temperature difference value, the higher the degree of consistency.

[0041] The neighborhood of the first area can be understood as an area with a common edge, as follows: Figure 2 As shown, the first region may include at most 4 neighboring regions; or, the neighboring regions of the first region may be understood as regions with a common edge and regions with a common vertex, as shown in Figure 3 As shown, the first area may include a maximum of 8 neighboring areas.

[0042] 102. Determine target correction data corresponding to the target temperature difference value.

[0043] In a specific implementation, different temperature difference values ​​may correspond to different correction data. For example, a mapping relationship between a preset temperature difference value and correction data may be pre-stored, and then, target correction data corresponding to the target temperature difference value may be determined based on the mapping relationship. The correction data may be used to adjust the consistency between the first region and its corresponding adjacent region, thereby ensuring the consistency of the display effect.

[0044] 103. Correct the first display parameter of the first area according to the target correction data to obtain a second display parameter.

[0045] In a specific implementation, the first display parameter of the first area can be corrected according to the target correction data to obtain the second display parameter, and then the consistency between the first area and its corresponding adjacent area can be adjusted, thereby ensuring the consistency of the display effect of the display screen and helping to improve the display effect of the entire display screen.

[0046] The first display parameter can be understood as the display parameter corresponding to the first area, and the display parameter can include at least one of the following: display brightness, display color, display frequency, display duration, current, voltage, power, etc., which are not limited here. The display brightness can include at least one of the following: the display brightness of the red lamp bead, the display brightness of the green lamp bead, and the display brightness of the blue lamp bead.

[0047] 104. Display the first area according to the second display parameter.

[0048] The second display parameter can be understood as the display parameter corresponding to the first area, and the display parameter can include at least one of the following: display brightness, display color, display frequency, display duration, current, voltage, power, etc., which are not limited here. The display brightness can include at least one of the following: the display brightness of the red lamp bead, the display brightness of the green lamp bead, and the display brightness of the blue lamp bead.

[0049] In a specific implementation, the first area can be displayed according to the second display parameter, and then the consistency between the first area and its corresponding adjacent area can be adjusted, thereby ensuring the consistency of the display effect of the display screen, that is, the intelligence of the display screen correction can be improved, which helps to improve the display effect of the entire display screen.

[0050] In some possible examples, the electronic device further includes a smart module, and the smart module includes a temperature sensor. The above step 101, determining the target temperature difference value between the first area and a plurality of neighboring areas corresponding to the first area, may include the following steps:

[0051] determining a first temperature value of the first area by the temperature sensor;

[0052] Determine, by the temperature sensor, temperature values ​​of a plurality of neighboring areas corresponding to the first area, to obtain a plurality of second temperature values;

[0053] Determine the difference between the plurality of temperature values ​​and the first temperature value to obtain a plurality of first difference values;

[0054] Performing a mean square error operation on the plurality of first difference values ​​to obtain a first mean square error;

[0055] Performing a mean operation on the multiple first differences to obtain a first mean;

[0056] The target temperature difference value is determined according to the first mean value and the first mean square error.

[0057] In a specific implementation, the electronic device further includes an intelligent module, and the intelligent module includes a temperature sensor. The intelligent module may be a controller, a control device, and the like.

[0058] Specifically, the first temperature value of the first area can be determined by a temperature sensor, and the temperature values ​​of multiple neighboring areas corresponding to the first area can be determined by the temperature sensor to obtain multiple second temperature values, and then the difference between the multiple temperature values ​​and the first temperature value can be determined to obtain multiple first difference values, each temperature value corresponds to a first difference value, and then a mean square error operation can be performed on the multiple first difference values ​​to obtain a first mean square error, which reflects the display fluctuation of the first area to a certain extent, and then a mean operation is performed on the multiple first difference values ​​to obtain a first mean, which reflects the display consistency between the neighboring areas of the first area, and then the target temperature difference value is determined according to the first mean and the first mean square error. In this way, the display consistency degree of the first area can be accurately determined according to the display consistency between the neighboring areas of the first area and the display fluctuation of the first area, thereby facilitating accurate correction and improving the display effect.

[0059] Furthermore, the target correction data may be a positive value, and the above step 103, correcting the first display parameter of the first area according to the target correction data to obtain the second display parameter, may be implemented as follows:

[0060] determining a second mean of the plurality of second temperature values;

[0061] When the second mean value is greater than the first temperature value, the second display parameter=(1+target correction data)*first display parameter;

[0062] When the second average value is less than or equal to the first temperature value, the second display parameter=(1-target correction data)*first display parameter.

[0063] In a specific implementation, when the second mean is greater than the first temperature value, the second display parameter = (1 + target correction data) * first display parameter; conversely, when the second mean is less than or equal to the first temperature value, the second display parameter = (1 - target correction data) * first display parameter. The correction direction is determined based on the comparison between the second mean and the first temperature value. In this way, targeted dynamic correction can be performed, and the consistency between the first area and its corresponding adjacent area can be adjusted, thereby ensuring the consistency of the display effect of the display screen and helping to improve the display effect of the entire display screen.

[0064] In some possible examples, the above step of determining the target temperature difference value according to the first mean value and the first mean square error may include the following steps:

[0065] determining a first temperature difference value corresponding to the first mean square error;

[0066] determining a first fine-tuning parameter corresponding to the first mean;

[0067] The target temperature difference value is determined according to the first fine-tuning parameter and the first temperature difference value.

[0068] In a specific implementation, a mapping relationship between a preset mean square error and a temperature difference value can be pre-stored, and then, a first temperature difference value corresponding to the first mean square error can be determined based on the mapping relationship. The mean square error reflects the display fluctuation of the first area to a certain extent. In this way, the corresponding temperature difference value can be preliminarily determined based on the actual fluctuation. A mapping relationship between a preset mean value and a fine-tuning parameter can also be pre-stored, and then, a first fine-tuning parameter corresponding to the first mean value can be determined based on the mapping relationship. The first mean value reflects the display consistency between the neighboring areas of the first area, that is, the temperature difference value can be further fine-tuned based on the actual display consistency. Then, a target temperature difference value can be determined according to the first fine-tuning parameter and the first temperature difference value, that is, the target temperature difference value = (1 + first fine-tuning parameter) * first temperature difference value, so that the final temperature difference value depth conforms to the actual situation. In this way, the display consistency degree of the first area can be accurately determined through the display consistency between the neighboring areas of the first area and the display fluctuation of the first area, thereby facilitating accurate correction and thus improving the display effect.

[0069] In some possible examples, the smart module further includes a storage module, in which a plurality of correction data are pre-stored; each correction data corresponds to a reference temperature difference value; the above step 102, determining the target correction data corresponding to the target temperature difference value, may include the following steps:

[0070] Determine a difference between the target temperature difference value and a reference temperature difference value corresponding to each correction data in the plurality of correction data to obtain a plurality of second difference values;

[0071] determining a minimum value among the plurality of second differences;

[0072] The correction data corresponding to the minimum value is determined as the target correction data.

[0073] In a specific implementation, the smart module further includes a storage module, in which a plurality of correction data are pre-stored; each correction data corresponds to a reference temperature difference value. For example, the storage module may include a flash disk (FLASH). Since the correction data is pre-stored, the corresponding correction data can be directly read based on the corresponding temperature difference value, which can improve the correction efficiency.

[0074] In a specific implementation, the difference between a target temperature difference value and a reference temperature difference value corresponding to each correction data in a plurality of correction data can be determined to obtain a plurality of second difference values, and the minimum value among the plurality of second difference values ​​can also be determined. In this way, the correction data closest to the actual temperature difference value can be determined, that is, the correction data corresponding to the minimum value is determined as the target correction data. In this way, the calibration accuracy can be guaranteed, thereby ensuring the display effect.

[0075] In some possible examples, the above step 103, correcting the first display parameter of the first area according to the target correction data to obtain the second display parameter, may include the following steps:

[0076] Correcting the first display parameter of the first area according to the target correction data to obtain a reference display parameter;

[0077] Obtaining a temperature difference value of each of the plurality of neighborhood areas to obtain a plurality of temperature difference values;

[0078] Performing a mean square error operation on the multiple temperature difference values ​​to obtain a second mean square error;

[0079] determining a target relative deviation between the first mean square error and the second mean square error;

[0080] Determining a first feedback adjustment parameter corresponding to the target relative deviation;

[0081] Feedback adjustment is performed on the reference display parameter according to the first feedback adjustment parameter to obtain the second display parameter.

[0082] The reference display parameter can be understood as the display parameter corresponding to the first area, and the display parameter can include at least one of the following: display brightness, display color, display frequency, display duration, current size, voltage size, power size, etc., which are not limited here. The display brightness can include at least one of the following: the display brightness of the red lamp bead, the display brightness of the green lamp bead, and the display brightness of the blue lamp bead.

[0083] In a specific implementation, the target correction data may be a positive value, and the first display parameter of the first area is corrected according to the target correction data to obtain the reference display parameter, which may be implemented as follows:

[0084] determining a second mean of the plurality of second temperature values;

[0085] When the second mean value is greater than the first temperature value, the reference display parameter=(1+target calibration data)*first display parameter;

[0086] When the second average value is less than or equal to the first temperature value, the reference display parameter=(1-target correction data)*first display parameter.

[0087] Specifically, when the second mean is greater than the first temperature value, the reference display parameter = (1 + target correction data) * first display parameter; conversely, when the second mean is less than or equal to the first temperature value, the reference display parameter = (1 - target correction data) * first display parameter. The correction direction is determined based on the comparison between the second mean and the first temperature value. In this way, targeted dynamic correction can be performed, and the consistency between the first area and its corresponding adjacent area can be preliminarily adjusted, thereby ensuring the consistency of the display effect of the display screen, which helps to improve the display effect of the entire display screen.

[0088] Next, the temperature difference value of each neighborhood area in the multiple neighborhood areas can be obtained to obtain multiple temperature difference values, and then the mean square error is calculated on the multiple temperature difference values ​​to obtain the second mean square error, and the target relative deviation between the first mean square error and the second mean square error is determined. The target relative deviation = (first mean square error - second mean square error) / (first mean square error + second mean square error). The target relative deviation not only reflects the degree of deviation, but also reflects the direction of deviation. The target relative deviation can ensure smooth adjustment of the display effect between the first area and its corresponding neighborhood area to a certain extent.

[0089] In a specific implementation, a mapping relationship between a preset relative deviation and a feedback adjustment parameter can be pre-stored, and then, a first feedback adjustment parameter corresponding to the target relative deviation can be determined based on the mapping relationship, and then the reference display parameter is feedback-adjusted according to the first feedback adjustment parameter to obtain a second display parameter, that is, the second display parameter = (1 + first feedback adjustment parameter) * reference display parameter. This can not only adjust the consistency between the first area and its corresponding adjacent area, but also ensure smooth adjustment of the display effect between the first area and its corresponding neighborhood area, thereby ensuring the consistency of the display effect of the display screen and helping to improve the display effect of the entire display screen.

[0090] For example, an electronic device may include a smart module, which may include FLASH, a temperature sensor, and a microprocessor (MCU). Multiple correction data are stored in the FLASH in the smart module, and a temperature sensor is added to the smart module. During the use of the display screen, if it is detected that there are regional differences in the screen temperature (the temperature difference value of different areas can be set), the MCU in the smart module sends a correction instruction, and the correction data matching the correction is sent to the smart module, and the display parameters are corrected using the correction data, and then the corresponding display is performed, thereby ensuring the consistency of the display effect.

[0091] It can be seen that the display screen correction method described in the embodiment of the present application is applied to an electronic device, which includes a display screen. During the display screen display process, a target temperature difference value between a first area and multiple neighboring areas corresponding to the first area is determined, and target correction data corresponding to the target temperature difference value is determined. The first display parameter of the first area is corrected according to the target correction data to obtain a second display parameter, and the first area is displayed according to the second display parameter. In this way, the target temperature difference value reflects the degree of display consistency between the first area and its corresponding adjacent areas to a certain extent, and then the correction data corresponding to the display consistency degree is determined. Then, the consistency between the first area and its corresponding adjacent areas can be adjusted based on the correction data, thereby ensuring the consistency of the display effect of the display screen, helping to improve the display effect of the entire display screen, and improving the intelligence of the display correction of the display screen.
