[0031] The power consumption of a display screen directly affects the efficiency of power resource consumption and the electricity costs paid by users. Furthermore, as the display screen operates over time, the power consumption and electricity costs increase significantly. In existing technologies, to control power consumption and the electricity costs of using the display screen, users add detection devices to the display screen's circuitry to monitor its power consumption. These detection devices include ammeters, power meters, and sensors. However, adding detection devices increases the production cost of the display screen, especially as larger displays require more detection devices, leading to a greater increase in production costs. Moreover, interference or damage to these detection devices can affect the accuracy of power consumption detection, resulting in lower accuracy of the power consumption data obtained through detection devices.
[0032] This application can accurately calculate the screen power consumption of the display screen when displaying a target image based on the first display power consumption and first operating parameters when the display screen displays a three-primary-color image, the second display power consumption when the display screen displays a pure black image, and the second operating parameters when the display screen displays a target image.
[0033] Please see Figure 1 The first embodiment of this application describes a method for obtaining display screen power consumption, which includes:
[0034] S1: Obtain the first display power consumption and first operating parameters when the display screen displays a three-primary-color image, and obtain the second display power consumption when the display screen displays a pure black image.
[0035] A display screen is a display device that displays image content based on electro-optical conversion. In this embodiment, the display screen can be a standalone display device or a display device used to splice together a combined display screen. The display screen includes multiple pixels, each pixel including pixels corresponding to three primary colors: red, blue, and green. The three-primary-color image displayed on the screen corresponds to three pure three-primary-color images. Specifically, the three-primary-color image includes a red image, a blue image, and a green image. The three primary colors include red light, blue light, and green light. The red image is the image that appears when only the red pixels corresponding to red light are active; the blue image is the image that appears when only the blue pixels corresponding to blue light are active; and the green image is the image that appears when only the green pixels corresponding to green light are active.
[0036] Therefore, the first display power consumption includes the red screen display power consumption when the display screen displays a red image, the green screen display power consumption when the display screen displays a green image, and the blue screen display power consumption when the display screen displays a blue image; while the first operating parameters include the red screen operating parameters when the display screen displays a red image, the green screen operating parameters when the display screen displays a green image, and the blue screen operating parameters when the display screen displays a blue image.
[0037] The circuitry that operates the display screen will have a basic power consumption. When the display screen is not lit, that is, when the display screen displays a pure black image, the basic power consumption of the display screen is the second display power consumption. Among them, the basic power consumption of the circuitry that operates the display screen using a backlight source includes the power consumption when the backlight layer emits light, and the second display power consumption will be more obvious.
[0038] S2: Based on the first display power consumption and the second display power consumption, the first brightness power consumption is obtained.
[0039] Since the second display power consumption is the basic power consumption for the operation of the display screen, the second display power consumption is fixed when the display screen displays images of different colors. Therefore, based on the difference between the first display power consumption and the second display power consumption, and combined with the resolution of the display screen, the first brightness power consumption of each pixel of the display screen corresponding to each of the three primary colors is obtained, which is power consumption data directly related to the three primary colors.
[0040] S3: Obtain the second working parameter when the display screen shows the target image.
[0041] The second working parameter is a parameter that indicates the working status of each pixel when the target image is displayed on the screen, and the second working parameter is a parameter of the same type as the first working parameter.
[0042] In one feasible embodiment, the first operating parameter is the maximum brightness of the display screen when displaying three primary colors. Specifically, when the three primary colors include red, blue, and green, the first operating parameter includes the maximum brightness of the display screen when displaying red, the maximum brightness of the display screen when displaying blue, and the maximum brightness of the display screen when displaying green. Brightness detection can be performed separately for each of the three primary colors on the display screen to obtain the maximum brightness of each pixel under each primary color image, which is then used as the first operating parameter.
[0043] The second operating parameter is the pixel brightness value of the three primary colors when the target image is displayed on the screen. This value can be calculated based on the pixel electrical signal values of each pixel when the target image is displayed on the screen, and used as the second operating parameter.
[0044] Specifically, the pixel brightness values of the three primary colors can be obtained when the display screen shows the target image through the following steps:
[0045] The pixel brightness value of the red pixel corresponding to red light when the target image is displayed on the screen can be obtained using the following formula:
[0046]
[0047] Where R is the pixel electrical signal value of the red pixel when the target image is displayed on the screen; O(R) is the optical linear value corresponding to the pixel electrical signal value of the red pixel; EOTF(R) represents the brightness value corresponding to the maximum value of the red channel electrical signal under a red screen, and the values of the green and blue channels being 0; EOTF(R) represents the pixel brightness value of the red pixel when the target image is displayed on the screen.
[0048] The pixel brightness value of the green pixel corresponding to the green light when the target image is displayed on the screen can be obtained using the following formula:
[0049]
[0050] Where G is the pixel electrical signal value of the green pixel when the target image is displayed on the screen; O(G) is the optical linear value corresponding to the pixel electrical signal value of the green pixel; EOTF(G) represents the brightness value corresponding to the maximum value of the green channel electrical signal under a green screen, and the values of the red and blue channels being 0; EOTF(G) represents the pixel brightness value of the green pixel when the display screen shows the target image.
[0051] The pixel brightness value of the blue pixel corresponding to blue light when the target image is displayed on the screen can be obtained using the following formula:
[0052]
[0053] Where B is the pixel electrical signal value of the blue pixel when the target image is displayed on the screen; O(B) is the optical linear value corresponding to the pixel electrical signal value of the blue pixel. EOTF(B) represents the brightness value corresponding to the maximum value of the blue channel electrical signal under a blue screen, and the values of the green and red channels being 0; EOTF(B) represents the pixel brightness value of the blue pixel when the target image is displayed on the screen.
[0054] In one feasible embodiment, the first operating parameter is the maximum electrical signal value when the display screen shows a three-primary-color image. Specifically, when the three-primary-color image includes a red image, a blue image, and a green image, the first operating parameter includes the maximum electrical signal values for displaying a red image, a blue image, and a green image. Taking common RGB color parameters as an example, in a red image, the maximum electrical signal value for the corresponding red pixel is 255; in a green image, the maximum electrical signal value for the corresponding green pixel is 255; and in a blue image, the maximum electrical signal value for the corresponding blue pixel is 255. The second operating parameter specifies that the pixel electrical signal value for each of the three primary colors is less than or equal to 255.
[0055] The second operating parameter is the pixel electrical signal value of the three primary colors when the target image is displayed on the screen. The pixel electrical signal value is the signal value of the red, blue, and green pixels output by the system with the display screen to the pixel based on the image color and contrast of the target image.

It represents the ratio of the pixel brightness value of each of the three primary colors of a pixel to the corresponding maximum brightness value.

[0072] S412: Based on the brightness ratio and the first brightness power consumption, obtain the second brightness power consumption of each of the three primary colors.
[0073] The second luminance power consumption corresponding to each of the three primary colors includes the luminance power consumption of the red pixel, the luminance power consumption of the green pixel, and the luminance power consumption of the blue pixel. Specifically, the second luminance power consumption corresponding to each of the three primary colors can be obtained through the following steps:

[0083] In this embodiment, the second brightness power consumption of each of the three primary colors of a pixel can be accurately obtained based on the brightness ratio and the first brightness power consumption.
[0084] Please see Figure 3 In one feasible embodiment, step S4: obtaining the second brightness power consumption based on the first operating parameters, the second operating parameters, and the first brightness power consumption, includes:
[0085] S421: Perform photoelectric conversion and linear normalization on the pixel electrical signal value based on the maximum value of the electrical signal to obtain the linear value of the electrical light.
[0086] The electro-optic linearity values of each of the three primary colors refer to the normalized electro-optical conversion linearity values obtained through photoelectric conversion and linear normalization processing. These values include the electro-optic linearity values of the red pixel, the red pixel's electro-optic linearity value, and the red pixel's electro-optic linearity value.
