Embodiment Construction

[0018] According to the present invention, the positions of the elements of the driver of the PDP are optimized so as to reduce the size of the loop in all three dimensions. Figure 5A The actuator of the present invention is shown from a plane (x, y), while Figure 5B The same circuit is shown from plane (y,z).

[0019] In these figures, switches I1 and I4 are placed adjacently on the same level of the x-axis, thereby reducing the loop of current flowing through them when closed. The same applies to switches I2 and I3, the loops used to reduce the current flowing through them when closed.

[0020] In addition, the access connectors CN1 and CN2 are located on the periphery of the board, adjacent to each other on the same edge of the board, here, the left edge of the board. Since all current loops pass through the two access connectors, the size of these loops is again reduced. In the preferred embodiment, the connector CN1 is located on the front side of the board, while th...

Abstract

The invention relates to a driver for a plasma display panel. According to the invention, in order to reduce the current loops during the sustain of the display cells, a novel driver architecture is proposed. The switches I1 and 14 of the sustain circuit, together with the switches I2 and 13, are disposed next to one another on the circuit board. In addition, the connectors accessing the display electrodes Ys and Yas are placed, at the periphery of the board, on the same edge.

Description

technical field [0001] The present invention relates to a driver for a plasma display panel. In particular, the present invention relates to a driver structure that reduces current loops during sustain of a display unit. Background technique [0002] Currently, there is a plasma display panel (hereinafter referred to as PDP) driver whose components are distributed between two boards, the components for controlling the sustain electrodes Ys of the display unit are provided on the first board, and the components for controlling The assembly of the addressing-sustaining electrode Yas of the display unit is disposed on the second board. figure 1 This situation is shown in . Means for controlling the sustain electrodes Ys of the display unit are mounted on the first board B1. Two switches I1 and I2 are connected in series between a power supply terminal T1 receiving a voltage Vs and a ground terminal T2. The voltage Vs represents the peak voltage of the sustain pulse signal t...
