The invention provides a terminal device, a control method thereof, a computer readable storage medium, and a computer device. The terminal device comprises a shell, a hidden module, a screen component, and a drive component, wherein the shell is provided with an installation groove, the hidden module is matched with the installation groove, the screen component covers on the shell, the drive component is arranged between the shell and the screen component, is connected with the hidden module, and is used for driving the hidden module to extend out of or retract into the installation groove from one end of the shell, and when the hidden module extends out of the installation groove, a part of the hidden module is still in the installation groove. According to the terminal device, components exposed on the front of the terminal are arranged on the hidden module arranged in the installation groove of the shell, the drive component drives the hidden module to extend out of or retract intothe installation groove, and the hidden module retracts into the installation groove and hides in the screen component, so that the screen ratio of the terminal device is increased, and the full screen design of the terminal device is realized.
