Abstract

The invention discloses an image refreshing method of a display screen in equipment and equipment with the display screen. The equipment comprises a control unit used for receiving an image, transmitting the image to a cache and refreshing the display screen by using the image in the cache. The reception of the image by the control unit is continuous. A period of an image corresponding to an odd row in N rows of each frame of image of the control unit is T1, and a period of an image corresponding to an even row in N rows of each frame of image of the control unit is T2. The image refreshing method comprises the steps of converting an image corresponding to an odd row in N rows of the image received in a recent T1 into a first image with the same row number of the display interface of the display screen in each T2, transmitting the first to the cache, and refreshing the display screen by using the first image. According to the image refreshing method and the equipment, a fact that an image without noise pollution is used by the display screen to carry out a refreshing operation is ensured, and the method and the equipment have the advantages of simple operation and clear visual display effect of the image displayed on the display screen.
