The stroke controller controls the retractable position of the projection screen for precise positioning. The remote control by wire is integrated with the power cord of the projection screen, which is convenient to use. The external remote control receiver is outside the projection screen and is controlled by the remote control; the built-in remote control is built in the electric projection screen with a built-in remote control receiving system. Hidden inside the projection screen makes the projection screen look more integrated and more beautiful.
