The invention provides a backlight adjusting method and device used for solving problems of backlight adjustment delay and poor precision of an electronic device in the prior art. The method includesthat a processor performs following backlight luminance adjustment steps, comprising determining a target backlight luminance value corresponding to a first illumination intensity sampling value according to the corresponding relation between the illumination intensity and the backlight luminance value and adjusting the backlight luminance of an LCD to the target backlight luminance value from aninitial backlight luminance value of the current moment through multiple times of backlight adjustment, on each first illumination intensity sampling value after acquiring a plurality of the first illumination intensity sampling values. Since the processor performs backlight luminance adjustment on each or almost each first illumination intensity sampling values and backlight luminance adjustmentis performed based on the target backlight luminance values corresponding to the first illumination intensity sampling values, the backlight adjustment of the electronic device is comparatively good in timeliness and high in precision.
Description
Technical field [0001] This application relates to the technical field of electronic equipment, and in particular to a backlight adjustment method and device. Background technique [0002] In order to clearly display various contents to users, most electronic devices have backlit display screens, such as liquid crystal displays (LCD). Because the environment change of the use scene of the electronic device is more complicated, and will cause the illumination intensity of the ambient light to change, in order to ensure that the content displayed on the display panel can be displayed clearly and maintain the constant visibility of the user’s eyes, the electronic device Need to adjust the backlight of its own display. [0003] At present, most electronic devices adopt a stepped backlight adjustment method, that is, the value range of the backlight brightness of the ambient light is divided into multiple small backlight brightness ranges (ie steps), and each small backlight brightness...
