摘要： Embodiments of this application provide a display screen aging compensation method, a circuit system, and an electronic device, and relate to the field of display technologies, to perform aging compensation on a display screen, thereby reducing a display difference. The display screen aging compensation method includes: first, obtaining display data of each display area, where the display data includes usage time t of the display area, a maximum gray level value Lev_max that is of each primary color and that is obtained before the display data is obtained, and an average gray level value Lev of each primary color within the usage time t; next, obtaining a decay ratio of each primary color of the display area based on the display data; and finally, performing aging compensation on each display area based on the decay ratio of each primary color of each display area.

摘要： This application discloses a voltage adjustment method and an electronic device. The method includes: obtaining a target luminance value of current display of a display pixel; determining a voltage increment value based on the target luminance value; and adjusting, based on the voltage increment value, an initial cathode voltage of an OLED device corresponding to the display pixel, where after voltage adjustment, a change amount between a luminance value of the display pixel and the target luminance value falls within a preset range. This application may be applied to an electronic device, and display quality of a display screen may be improved while power consumption of the display screen is reduced.

摘要： This application discloses a photographing method and apparatus, to overcome blurring that occurs during photographing. When a zoom ratio is greater than a first zoom ratio threshold, a long-focus camera is started to capture an image. A zoom ratio of the long-focus camera is greater than or equal to the first zoom ratio threshold. Because a high zoom ratio causes large shake, a rotational blur occurs in the image. According to the photographing method disclosed in this application, a first neural network model for rotational image deblurring is used to implement rotational image deblurring processing. In this way, high imaging quality of an image, a video, or a preview image is presented to a user to some extent, and an imaging effect may not be inferior to an effect of photographing with a tripod.
