Embodiment Construction

[0017] Hereinafter, the plasma display device in the present invention will be described in detail with reference to preferred embodiments and accompanying drawings. figure 1 It is a schematic diagram of an embodiment of the plasma display panel structure in the present invention.

[0018] like figure 1 As shown, the plasma display panel includes: a pair of sustain electrodes on the upper substrate 10 , that is, a scan electrode 11 and a sustain electrode 12 ; and an address electrode 22 on the lower substrate 20 .

[0019] The above-mentioned sustain electrode pair 11, 12 generally includes transparent electrodes 11a, 12a and bus electrodes 11b, 12b formed by indium tin oxide (Indium-Tin-Oxide; ITO), and the above-mentioned bus electrodes 11b, 12b can be made of silver (Ag ), chromium (Cr) and other metals or chromium / copper / chromium (Cr / Cu / Cr) superposition formed, or chromium / aluminum / chromium (Cr / Al / Cr) superposition formed. The bus electrodes 11b, 12b are located on the...

Abstract

The invention discloses a plasma display device, including a first drive section providing a driving signal to the sweeping electrodes formed on the plasma display panel; a second drive section providing a driving signal to the sustain electrode; and a drive control section, generating a control signal controlling the operations of the first and second drive sections and transmitting the control signal to the first and second drive sections. If error occurs when the drive control section transmits the control signal to the first drive section, the drive control section will terminate the transmission of the drive control section to the second drive section. When the invention transmits a control signal to one of the scanning drive section and the sustain drive section, if error occurs, the invention will terminate the transmission of the drive control section to the other drive section, accordingly the invention can prevent damage to the drive circuit and improve the reliability of the plasma display device.

Description

technical field [0001] The present invention relates to a plasma display device, and more specifically, to a plasma display device that drives a driving portion of a plasma display panel. Background technique [0002] A plasma display device comprising a panel in which a plurality of discharge cells (cells) are formed between a rear substrate provided with a spacer and a front substrate opposite thereto, and selectively discharges the plurality of discharge cells for a selected image signal (cell) is discharged, and the vacuum ultraviolet rays generated by the discharge cause the phosphor to emit light to display an image. [0003] In order to efficiently display images, a plasma display device includes a drive control device such as a drive unit that processes input general image signals and supplies drive signals to a plurality of electrodes included in the panel. [0004] When the above-mentioned drive unit and the drive control circuit are damaged, the image quality of ...
