The method for amplifying or reducing the target information displayed on the display interface comprises the following steps: and amplifying or reducing the target information displayed on the display interface to a preset proportion occupying the total area of the display interface. For example, the target information displayed on the display interface is enlarged or reduced to 1/2 of the total area occupied by the display interface, or the target information displayed on the display interface is enlarged or reduced to 2/3 of the total area occupied by the display interface. Under the condition, the displayed target information is amplified or reduced to a proper size, and the target information is prevented from being displayed too small or too large, so that the size of the displayed target information is adjusted to be in line with the habit of the user, and the user experience is better.
