Title: Driving system for plasma display
Inventor: TANAKA AKIO
IPC: G09G3/296
Filed: 1990-04-19
Abstract: PURPOSE:To drastically decrease the flickers arising from a gradation display observed heretofore by overlapping sub-fields of G and R with time and shortening the spacing between the sub-fields. CONSTITUTION:The plural sub-fields of the AC refresh type plasma display having a circuit to obtain gradation by dividing one field to the plural sub-fields are driven by overlapping the display periods of the sub-fields with time. Namely, the sub-fields of the G and R are overlapped with time to shortened the inter-sub-field spacing to 1/3 the inter-sub-field spacing of the conventional system. This spacing corresponds to the spacing obtd. by shortening the field period to about 1/3 (triples the fresh frequency) and the flickers are decreased down to a negligible level. The flickers arising from the gradation display are drastically decreased in this way.

Title: Chopper noise prevention circuit
Inventor: TSUKAHARA HITOSHI
IPC: H02M3/155
Filed: 1986-05-08
Abstract: PURPOSE:To prevent the occurrence of noise from an especially long load drive line between a chopper circuit and a load, by connecting a common mode choke filter between the chopper circuit and the load. CONSTITUTION:A transistor 3 of a chopper circuit 1 is driven by the control pulse from a control portion 5 and interrupted. This interruption signal of the transistor 3 drives a load 13 through a common mode choke filter 9 and a load drive line 11. As a result, as this interruption signal of the transistor 3 does not directly interrupt and drive the load 13, but drives through the common mode choke filter 9, the common mode voltage waveform, i.e., the interruption signal of the transistor 3, gets dull. Thus the chopper noise is prevented from occurring to the load drive line 11 as the common mode high frequency noise.
