Field of the Invention The present invention relates to a television having a screen switching function for changing the scanning direction of the television in various directions so that the screen displayed on the CRT can be switched to various screen states. In a television equipped with image processing means for extracting a video signal and then displaying the image on a CRT, a predetermined screen switching signal is output so that the screen can be switched in a direction desired by the viewer with a predetermined screen switching key. A switching data storage unit 20 and a key input means 18, which store a plurality of switching data for switching direction recognition corresponding to a screen switching signal output from the key input means 18; When the screen switching signal is input from the control unit, the screen switching signal is input based on the switching data of the switching data storage unit 20 to determine the switching direction. A microcomputer 24 for outputting a screen switching control signal of the display device; and a screen switching means 26 for driving switching to switch the screen displayed on the CRT in a predetermined direction according to the screen switching control signal from the microcomputer 24. The screen switching means 26 is installed at the vertical deflection coil end of the deflection yoke 12 and switched according to the screen switching control signal of the microcomputer 24 to perform the screen switching operation in the vertical direction. A first switching unit S1 for changing the current flow in the vertical deflection coil, and a horizontal deflection coil end of the deflection yoke 12 so as to be switched according to the screen switching control signal of the microcomputer 24, and The second switching unit (S2) for changing the current flow in the horizontal deflection coil so as to perform the screen switching operation.
