Problems solved by technology

In particular, in the PAL driving method, when reset discharge is performed by a reset pulse supplied within a reset period, a discharge error or low discharge occurs according to a change in temperature, which causes unstable discharge

Abstract

A method of driving a Plasma Display Panel (PDP) having discharge cells formed where sustain electrodes cross address electrodes, the method including: processing an input image signal received from an external device and dividing the processed input image signal into frames, each frame including a plurality of subfields, each subfield having a corresponding gray scale weight; and supplying a voltage with a pulse waveform, the pulse waveform having the form of a slope during a predetermined period in the subfield. The method further includes: determining a type of the input image signal; and if the image signal is a Phase Alternation Line (PAL) signal, adjusting the gradient of the slope according to a temperature of the PDP.

Description

technical field [0001] The present invention relates to a method of driving a plasma display panel (PDP). More specifically, it relates to a method of driving a PDP, wherein a frame constituting a display period is divided into a plurality of subfields for time-division grayscale display, each subfield including a reset period, an address period, and a sustain-discharge period . Background technique [0002] A plasma display panel (PDP) has drawn public attention because it can be easily fabricated into a large-sized flat panel display. The PDP displays images using a discharge phenomenon. Generally, PDPs can be classified into DC PDPs and AC PDPs according to driving voltages. Since DC PDPs have a long discharge delay time, AC PDPs are currently mainly being developed. [0003] A representative AC PDP is a 3-electrode AC surface discharge PDP that includes 3 electrode groups and is driven by an AC voltage. Since the 3-electrode surface discharge PDP composed of a plura...
