The invention relates to a method and a device for drawing screen images. The method includes creating a memory buffer area object according to the size of a screen; judging factors such as the signal intensity and the update frequency of a corresponding memory area in real time, dynamically transmitting signal density information to a screen segmentation controller according to signal intensity conditions, segmenting a memory into blocks according to the factors and respectively drawing corresponding dynamic signal resources according to the blocks of the memory; copying images in the segmented memory blocks on the screen. The method and the device have the advantages that problems of poor dynamic image drawing performance and high resource occupation under the conditions of large screens and high signal frequency are solved, and massive signals can be dynamically drawn by the aid of the method and the device.
