A display device to change an image displayed in a display area when the display area is changed includes a memory, a location output unit and a screen display unit. The memory stores size information of a display area displayed on a screen and the image data of the displayed image. The location computing unit computes a start point of the changed display area when the display area is changed. The display unit decodes data corresponding to the size of the display area based on the computed new start point from the image data to display the decoded data in the display area. Since the start point is obtained with center point of the changed display area and its size information and then a display area to be displayed is determined based on the start point, a current search location is maintained even when the screen is swung.

Provided are a frame rate adjusting method and apparatus for a display screen, a terminal, and a storage medium. The method includes: obtaining (S110), in response to detecting a swiping operation, a screen scrolling speed; in response to the screen scrolling speed satisfying a predetermined frame-rate-adjustment condition, obtaining (S120) a current frame rate of a screen, a predetermined target frame rate, and a screen scrolling time length corresponding to the swiping operation; determining a current frame period based on the current frame rate, and determining a target frame period based on the predetermined target frame rate (S130); determining (S140) a frame period change based on the current frame period, the target frame period, and the screen scrolling time length; and adjusting (S150) the current frame rate of the screen based on the frame period change during a screen scrolling period.
