The invention discloses a terminal screen display method and device. The method comprises the following steps of obtaining data in a terminal memory, wherein the data reflects display of a terminal screen; judging whether the display of the terminal screen changes according to the data; if yes, determining a picture used for displaying the changed terminal screen; and sending the picture to a user side for displaying the picture through the user side. Only when the display of the terminal screen changes, the picture used for displaying the changed terminal screen is determined and is sent to the user side, so that the number of pictures sent to the user side can be reduced, the phenomenon of lag can be effectively relieved in the scene with the slow network transmission rate, and thus a problem caused by sending the picture to a client at the fixed frame rate in the existing technology is solved.
