And S220, loading Mura compensation data corresponding to the highlight mode when the highlight mode is detected.
Wherein, under different light environment, the display screen is provided with different mode. When the light intensity in the environment is higher, the display screen can be automatically switched to a high-brightness mode; when the light intensity is lower, the display screen can be automatically switched to the common mode. I.e. the operation modes of the display screen include a normal mode and a highlight mode. The normal mode and the brightness mode are defined according to brightness data displayed on the display screen.
And the IC chip detects the working mode of the display screen, and when the common mode is detected, the Mura compensation data corresponding to the common mode is searched according to the common mode, so that the Mura compensation data corresponding to the working mode is loaded to compensate the display screen.

In one embodiment, referring to fig. 3, the generation manner of the Mura compensation data includes:
s310, acquiring the brightness data of the detection picture displayed by the display screen in a preset working mode.
The electronic equipment starts a preset working mode, the display screen displays a detection picture corresponding to the preset working mode, and the detection picture is photographed through the image acquisition device to obtain an image of the detection picture. And extracts corresponding luminance data for each pixel of the detection picture image. The image acquisition device sends the extracted brightness data of each pixel to the data processing device, namely the data processing device acquires the brightness data of a detection picture corresponding to the preset working model. Specifically, in a preset working mode, under a plurality of gray scales, the display screen displays a pure-color gray scale picture corresponding to any one of the three primary colors of RGB, wherein the pure-color gray scale picture can be a red gray scale picture, a green gray scale picture or a blue gray scale picture. The three-primary-color pure-color gray scale picture displayed by the display screen is shot through the image acquisition device respectively so as to obtain the brightness data of the detection picture displayed by the display screen.
And S320, generating Mura compensation data corresponding to the working mode according to the acquired brightness data and preset target brightness data.
Under a preset working mode, the display screen displays a pure-color gray scale picture corresponding to RGB three primary colors, target brightness data are preset in the pure-color gray scale picture, and the brightness data corresponding to the pure-color gray scale picture can be acquired through the image acquisition device. In general, the preset target luminance data is not consistent with the actually acquired luminance data. Therefore, corresponding Mura compensation data can be generated through the acquired brightness data and the preset target brightness data. For example, the Mura compensation data corresponding to the working mode is generated according to the difference between the preset target luminance data and the actually acquired luminance data by calculating the difference between the preset target luminance data and the actually acquired luminance data.
In this embodiment, the electronic device starts a preset working mode, and acquires the luminance data of the detection picture displayed by the display screen in the preset working mode, so as to obtain the Mura compensation data corresponding to the preset working mode according to the acquired luminance data and the preset target luminance data. And then different Mura compensation data can be selected according to the display screens in different working modes.
In one embodiment, the operating mode includes a normal mode. Referring to fig. 4, in a preset operating mode, acquiring luminance data of a detection picture displayed by a display screen includes:
s410, in a common mode, acquiring first brightness data of a detection picture displayed by a display screen.
Referring to fig. 4, generating Mura compensation data corresponding to the working mode according to the acquired luminance data and the preset target luminance data includes:
and S420, generating Mura compensation data corresponding to the common mode according to the acquired first brightness data and preset first target brightness data.
In a common mode, a display screen displays a pure-color gray scale picture corresponding to RGB three primary colors, first target brightness data are preset in the pure-color gray scale picture, and first brightness data corresponding to the pure-color gray scale picture can be acquired through an image acquisition device. The preset first target luminance data is inconsistent with the first luminance data actually acquired. Therefore, Mura compensation data corresponding to the common mode can be generated through the acquired first brightness data and the preset first target brightness data. For example, the Mura compensation data corresponding to the normal mode is generated according to the difference between the preset first target luminance data and the actually acquired first luminance data by calculating the difference between the preset first target luminance data and the actually acquired first luminance data.
In this embodiment, the electronic device starts a normal mode, and in the normal mode, first luminance data of a detection picture displayed by the display screen is acquired, so that Mura compensation data corresponding to the normal mode is obtained according to the acquired first luminance data and preset first target luminance data. And then Mura compensation data corresponding to the common mode can be selected for the display screen in the common mode.
In one embodiment, the operating mode is a highlight mode. Referring to fig. 5, in a preset operating mode, acquiring luminance data of a detection picture displayed by a display screen includes:
and S510, acquiring second brightness data of the detection picture displayed by the display screen in a high-brightness mode.
Referring to fig. 5, obtaining Mura compensation data corresponding to the working mode according to the obtained luminance data and the preset target luminance data includes:
and S520, generating Mura compensation data corresponding to the highlight mode according to the acquired second brightness data and preset second target data.
In one embodiment, after generating the Mura compensation data corresponding to the operation mode, the method further includes: and storing the generated Mura compensation data.
In the highlight mode, the display screen displays a pure-color gray scale picture corresponding to the three primary colors of RGB, second target brightness data are preset in the pure-color gray scale picture, and second brightness data corresponding to the pure-color gray scale picture can be acquired through the image acquisition device. The preset second target luminance data is inconsistent with the second luminance data that is actually acquired. Therefore, Mura compensation data corresponding to the high brightness mode can be generated through the acquired second brightness data and the preset second target brightness data. For example, the Mura compensation data corresponding to the highlight mode is generated according to the difference between the preset second target luminance data and the actually acquired second luminance data by calculating the difference between the preset second target luminance data and the actually acquired second luminance data.
In this embodiment, the electronic device starts a highlight mode, and in the highlight mode, second luminance data of a detection picture displayed by the display screen is acquired, so that Mura compensation data corresponding to the highlight mode is obtained according to the acquired second luminance data and preset second target luminance data. And then Mura compensation data corresponding to the highlight mode can be selected for the display screen in the highlight mode.
