PURPOSE: To theoretically turn transient time until delay time and signals are changed to zero and to obtain a horizontal deflection device for which the change speed of a deflection potential is fast by generating the deflection potentials corresponding to the respective pixels of RGB, switching them corresponding to deflection and driving a flat CRT by the switched deflection potential of large amplitude. CONSTITUTION: The respective horizontal potentials of plural potential circuits 7 are equivalent to the potentials of the respective stages of staircase waves Vn, that are the deflection potentials of the respective stages of the staircase waves generated by DAC in a conventional horizontal deflection device. The respective deflection potentials are inputted to a multiplexer 8, time-division controlled by a control circuit 1, successively switched from the potential 1 to the potential (n) and added to an output circuit 5 as the signals of the large amplitude. The signals of the large amplitude pass through the output circuit 5 and are impressed to the horizontal deflection electrode 6 of the flat CRT. Thus, the signals capable of driving the flat CRT are directly generated and they are passed through the output circuit 5 and impressed to the horizontal deflection electrode 6 of the flat CRT. |
