Embodiment Construction

[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0019] A plasma display device of the present invention includes a plasma display panel and a drive unit.

[0020] FIG. 1 is a diagram for introducing a structure of a plasma display panel that may be included in a plasma display device of an example of the present invention.

[0021] Analyzing Fig. 1, then the plasma display panel that can be included in the plasma display device of an example of the present invention is by the front substrate 101 of configuration mutually side by side scan electrode (102, Y) and sustain electrode (103, Z), and front substrate 101 opposite The rear substrate 111 is bonded with the address electrodes 113 intersecting the scan electrodes 102 and the sustain electrodes 103 .

[0022] On the upper portion of front substrate 101 where scan electrodes 102 and sustain electrodes 103 are formed, upper dielectric layer 1...

Abstract

A plasma display apparatus is provided to reduce the size of drivers and manufacturing cost by driving the plasma display apparatus using one driver. A plasma display apparatus includes a plasma display panel, a scan drive IC(Integrated Circuit)(200), a sustain voltage switch unit(S3), and a falling ramp switch unit(S4). The plasma display panel includes scan and sustain electrodes in parallel. The scan drive IC having first and second switch units is connected to the scan electrodes between the other end of the first switch unit and one end of the second switch unit. The sustain voltage switch unit supplies a sustain voltage to the scan electrodes through a first path and the scan drive IC and a rising ramp signal to the scan electrode through a second path different from the first path and the scan drive IC. The falling ramp switch unit supplies the ground voltage to the scan electrodes through a third path different from the first and second paths and the scan drive IC, and a falling ramp signal to the scan electrodes through a fourth path different from the first, second, and third paths and the scan drive IC.

Description

technical field [0001] The present invention is an invention related to a plasma display device (Plasma Display Apparatus). Background technique [0002] The plasma display device includes a plasma display panel and a driving unit. Usually, in the plasma display panel, phosphor layers are formed in discharge strings (Cells) divided by barrier ribs, and a plurality of electrodes (Electrodes) are formed at the same time. Also, a driving signal is supplied to the discharge strings through the electrodes. Therefore, a discharge is generated in the discharge string according to the provided driving signal. Wherein, when a discharge is generated in the discharge string by a driving signal, the discharge gas charged in the discharge string releases vacuum ultraviolet rays (Vacuum Ultraviolet rays), and the vacuum ultraviolet rays make the phosphors formed in the discharge string emit light, thereby generating visible light. Using this visible light, images are displayed on the sc...
