[0047] In an exemplary embodiment, as shown in FIG. 1 , a display device brightness compensation method is provided. The display device brightness compensation method is applied to a display device. The display device brightness compensation method includes S101-S104:

[0048] S101: Obtain the current usage time of the display device to be compensated.

[0049] In the present application, when brightness compensation is required for a display device, the current usage time of the display device to be compensated may be obtained.

[0050] The display device may be any personal computer, laptop, smart phone, tablet computer, IoT device, etc. having a display component, and the display component may include an LED screen, an OLED screen, etc. The current usage time may be the total display time of the screen of the display device at the current moment.

[0051] It should be understood that the embodiments of the present application do not limit how to obtain the current usage time of the display device to be compensated. In some embodiments, the display device can record the display time of the screen each time. When brightness compensation is required, the current usage time of the display device can be obtained by accumulating the display time of the screen of the display device each time.

[0052] S102: Input the current usage time into a brightness attenuation law function of the display device to obtain a current brightness attenuation rate of the display device.

[0053] In the present application, after the display device obtains the current usage time of the display device to be compensated, the current usage time can be input into the brightness attenuation law function of the display device to obtain the current brightness attenuation rate of the display device.

[0054] The brightness attenuation law function is generated based on the original brightness data of the display device at multiple time nodes within the time period to be tested.

[0055] The brightness decay rate may be the rate at which the brightness of the screen of the display device decreases due to aging or wear after a period of use.

[0056] It should be understood that the embodiments of the present application do not limit how to generate the brightness attenuation law function. In some embodiments, the display device can obtain the original brightness data of the display device at multiple time nodes within the time period to be tested. Subsequently, the display device can normalize the original brightness data of the multiple time nodes to obtain the brightness attenuation rate of the multiple time nodes. Finally, the display device can generate the brightness attenuation law function of the display device according to the brightness attenuation rate of the multiple time nodes.

[0057] Wherein, the above-mentioned time period to be tested can be specifically set according to actual conditions, and accordingly, the time period to be tested can be divided into multiple time nodes according to the same or different time intervals. Exemplarily, the time period to be tested can be set to 2000 hours, and each 200 hours can be set as a time node. Exemplarily, the time period to be tested can be set to 2000 hours, and the multiple time nodes can include 0 hours, 170 hours, 340 hours, 500 hours, 660 hours, 850 hours, 1000 hours, 1170 hours, 1330 hours, 1500 hours, 1830 hours and 2000 hours.

[0058] It should be understood that the embodiments of the present application do not limit how to obtain the original brightness data of the display device at multiple time nodes within the time period to be tested. In some embodiments, the display device can be controlled to continuously display a fixed image of preset brightness within the time period to be tested, and then the brightness of the screen of the display device can be measured at each time node by a photometer and the measured original brightness data can be recorded. Subsequently, the original brightness data of the display device at multiple time nodes within the time period to be tested is obtained from the photometer.

[0059] It should be noted that the generation of the above-mentioned brightness attenuation law function can be executed by a display device or by other external terminal devices or servers, and the embodiments of the present application do not limit this.

[0060] The preset brightness may be any brightness, which is not limited in the present embodiment, for example, 255 grayscale.

[0061] Exemplarily, the display device is at an initial driving voltage Under the condition of 100%, a fixed image with a brightness of 255 grayscale is loaded on the screen and displayed continuously for 2000 hours. The photometer measures the brightness of the screen of the display device at various time points within 2000 hours to obtain the brightness data of various time points within 2000 hours. The original brightness data of various time points within 2000 hours may include 2000 nits (nit), 1921 nit, 1883 nit, 1841 nit, 1802 nit, 1782 nit, 1760 nit, 1722 nit, 1703 nit, 1681 nit, 1643 nit and 1601 nit.

[0062] For example, Figure 2 A schematic diagram of a brightness attenuation rate provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, in order to facilitate the analysis of the original brightness data and generate the brightness attenuation law function of the display device, the original brightness data of each time node can be normalized to obtain the brightness attenuation rates of multiple time nodes, including: 1, 0.96, 0.94, 0.92, 0.90, 0.89, 0.88, 0.86, 0.85, 0.84, 0.82, 0.80.

[0063] It should be understood that the embodiments of the present application do not limit how to generate the brightness attenuation law function of the display device. In some embodiments, the display device can use the least squares method to fit the brightness attenuation rates of multiple time nodes to obtain the brightness attenuation law function of the display device.

[0064] Exemplarily, the initial function model of the least square method can be shown as formula (1), where x is the continuous use time of the screen, It means that the corresponding continuous use time The brightness decay rate of the screen.

[0065] (1)

[0066] For example, the brightness decay rates of multiple time nodes obtained by normalizing the original brightness data of each time node can be input into formula (1) respectively, thereby obtaining a brightness decay law function generated by least squares fitting, which can effectively describe the brightness decay law of the screen over time. The brightness decay law function can be shown in formula (2). Correspondingly, the function curve of the brightness decay law function can be as follows Figure 3shown.

[0067] (2)

[0068] It should be noted that, in order to ensure the accuracy and stability of the fitting effect, the polynomial stage number n in the least squares method can be between 3 and 10. For example, the polynomial order n in formula (2) is 4.

[0069] For example, after generating the brightness attenuation law function of the display device, if it is necessary to perform brightness compensation of the display device, the current usage time can be , input into formula (2), and calculate the screen attenuation rate at this time .

[0070] S103 . Determine a current voltage loss value of the display device according to a current brightness attenuation rate of the display device.

[0071] In this step, the display device inputs the current usage time into the brightness attenuation law function of the display device to obtain the current brightness attenuation rate of the display device. The current voltage loss value of the display device can be determined based on the current brightness attenuation rate of the display device.

[0072] It should be understood that the embodiments of the present application do not limit how to determine the current voltage loss value of the display device according to the current brightness decay rate of the display device. In some embodiments, the display device may first input the current brightness decay rate into the voltage-brightness relationship function of the display device to obtain the driving voltage value corresponding to the current brightness decay rate. Subsequently, the display device may determine the current voltage loss value of the display device according to the driving voltage value corresponding to the current brightness decay rate and the initial driving voltage value of the display device.

[0073] Among them, the voltage-brightness relationship function is used to reflect the screen input voltage The brightness output it produces The mathematical relationship between them, the voltage-brightness relationship function can be shown as formula (3).

[0074] (3)

[0075] Among them, the current voltage loss value of the display device can be obtained by formula (4).

[0076] (4)

[0077] For example, the screen attenuation rate at this time is As brightness output Substituting into formula (3), we can get the driving voltage value corresponding to the current brightness decay rate: Then, the driving voltage value corresponding to the current brightness decay rate is and the initial driving voltage value of the display device , substituting into formula (4), the current voltage loss value of the display device is obtained .

[0078] It should be understood that the above-mentioned current voltage loss value is the voltage loss value of the screen of the display device in the attenuation state relative to the initial state.

[0079] S104 . Determine a compensated driving voltage value of the display device according to a current voltage loss value of the display device.

[0080] In this step, after the display device determines the current voltage loss value of the display device according to the current brightness attenuation rate of the display device, the compensated driving voltage value of the display device can be determined according to the current voltage loss value of the display device.

[0081] For example, in order to compensate for the brightness attenuation caused by screen aging, the compensated driving voltage value of the display device can be obtained by formula (5).

[0082] (5)

[0083] in, is the compensated driving voltage value of the display device, is the initial driving voltage value, It is the compensated driving voltage value of the display device.

[0084] In some embodiments, after determining the compensated driving voltage value of the display device according to the current voltage loss value of the display device, the display device may adjust the input voltage of the display device according to the compensated driving voltage value.

[0085] Exemplarily, the compensated driving voltage value of the display device may be As the input voltage of the screen of the display device, it offsets the brightness attenuation caused by aging of the screen and restores the original brightness level.

[0086] The display device brightness compensation method provided in this embodiment, by fitting the brightness attenuation law function of the display device and automatically compensating according to the brightness attenuation law function, significantly extends the service life of the display device, reduces the frequency of early replacement of the device due to screen aging, and saves costs for users. Compared with the related art, the present application can dynamically adjust the screen voltage of the display device to offset the aging effect, maintain the stability of the screen of the display device and the high-quality display effect, so that users can continue to enjoy excellent contrast and vivid color reproduction, and enhance the overall visual experience of the display device.

[0087] In addition, the above display device brightness compensation method can extend the screen life, indirectly reduce the amount of electronic product waste, reduce resource consumption and environmental pollution. The display device brightness compensation method is not only applicable to OLED display devices, but also to any other type of display devices.

[0088] The brightness compensation method for a display device provided in an embodiment of the present application first obtains the current usage time of the display device to be compensated. Secondly, the current usage time is input into the brightness attenuation law function of the display device to obtain the current brightness attenuation rate of the display device, and the brightness attenuation law function is generated based on the original brightness data of multiple time nodes of the display device within the time period to be measured. Thirdly, according to the current brightness attenuation rate of the display device, the current voltage loss value of the display device is determined. Finally, according to the current voltage loss value of the display device, the compensated driving voltage value of the display device is determined. Since the current brightness attenuation rate corresponding to the current usage time is determined by the brightness attenuation law function, the current voltage loss value is determined by the current brightness attenuation rate, and then the compensated driving voltage value of the display device is determined. In this way, the compensated driving voltage value corresponding to each usage time can be accurately determined. Compared with setting fixed parameters to adjust the brightness, the compensation accuracy is greatly improved, thereby improving the brightness compensation effect of the display device.
