AI Technical Summary

Problems solved by technology

However, if the content of xenon is increased, other driving performances will decrease due to the increase of high discharge voltage
Therefore, increasing the black luminance during initialization will lower the contrast, and increasing the black luminance during initialization will also have a bad influence on the realization of the contrast ratio (Contrast Ratio) and the afterimage characteristics

Embodiment Construction

[0041] An embodiment of the driving method of the plasma display screen of the present invention will be described in detail below with reference to FIGS. 4 to 9 b.

[0042] As shown in Fig. 4 to Fig. 5b, the driving method of the plasma display screen in the embodiment of the present invention divides a frame into n (an integer of n refers to quantity) sub-fields including initialization period, address period, sustain period and erasure period. to drive. The above initialization period is only included in a part of the n subfields.

[0043] Specifically, the characteristics of the driving method of the plasma display screen in the first embodiment of the present invention are: 1--n / 4 subfields in the n subfields include the initialization period, the address period, the maintenance period and the erasing period, and the remaining subfields The domain includes address period, maintenance period and erasure period.

[0044] The 1--n / 4 subfields containing the initialization ...

Abstract

A method for driving plasma display screen includes externally-adding ramp-up and tramp-dn on scan electrode by partial subfield in n numbers of subfields in order to make discharge unit be initialized and omitting said ramp-up by at least one sub-field in addition to said partial sub-field for realizing high contrast of said display screen and for improving residual image character.

Description

technical field [0001] The present invention relates to the technology of the driving method of the plasma display screen, especially refers to a driving method of the plasma display screen which can minimize unnecessary wall charges remaining after quench discharge to prevent misdischarge. Background technique [0002] Plasma Display Panel (hereinafter referred to as "PDP") is an inert mixture of helium + xenon (He+Xe), neon + xenon (Ne+Xe), helium + xenon + neon (He+Xe+Ne) Under the action of ultraviolet rays generated during gas discharge, the phosphor emits light to display images. Such a plasma display (PDP) can not only be thinned and enlarged, but also the image quality can be further improved with the further development of recent technologies. [0003] As shown in FIG. 1, the discharge cell of the three-electrode surface discharge type plasma display screen is configured with a pair of sustain electrodes including a scan electrode 30Y and a sustain electrode 30Z ar...
