摘要: In plasma displays in different inch sizes, there is a disadvantage in that because each of the plasma displays in different inch sizes has an output semiconductor device with a different outer shape, a pitch of the external lead and the number of the output semiconductor devices vary, so that printed circuit boards need be designed differently for the different inch sizes. A hybrid integrated circuit includes mounting portions which are composed of a conductive path on an insulated metal substrate, and into which at least an output semiconductor device of a discharge maintaining circuit is incorporated, and includes external terminals arranged at a constant pitch. When the inch size of the plasma display is changed, the mounting portions are designed to have a size enough to accommodate the output semiconductor device for the greatest inch size. Thus, the same hybrid integrated circuit is commonly used.

摘要: A power recovery circuit includes a capacitor (C2) for accumulating power recovered from a panel (C1), a third switching element (Q3) for discharging the capacitor (C2), a fourth switching element (Q4) for charging the capacitor (C2), and a level shift unit for shifting a control signal for controlling Q4 to the voltage level of the capacitor (C2). The threshold voltage of Q4 is set higher than that of Q3. Accordingly, Q4 can be prevented from malfunctioning due to a decrease in the voltage of the capacitor (C2).
