The embodiments of the present application disclose a display driving method for driving a display system, comprising: receiving K image information sequentially; generating combined image information according to the K image information; and displaying a combined image based on the combined image information; wherein generating combined image information comprises: receiving kth image information, storing the kth image information as a data matrix with mk rows and nk columns, and recording a storage address associated with nkth data in each row to acquire a kth address table, wherein various rows in the data matrix are stored sequentially by using addresses in a (k−1)th address table as first addresses, where K, mk, nk are integers greater than 1, and k is an integer greater than or equal to 1 and less than or equal to K; and repeating the above operations until k is equal to K.
