Addressing and display separated driving method for driving plasma display panel

Abstract

The invention discloses a driving method for plasma which comprises: displaying according to subfield, dividing each field wave shape into a plurality of subfield wave shape and a erasing period wave shape ; each subfield wave shape includes resetting period, addressing period and maintaining period, employing different Y electrode resetting period driving wave shape for displaying bright images or dark images; erasing period Y electrode of each field wave shape is descending oblique wave voltage and all subfields have the same addressing period driving wave shape; each subfield maintaining period has the same wave shape, and has different amount of maintaining pulse according to each subfield weight.

Description

technical field [0001] The invention belongs to the technical field of gas discharge, and relates to a driving method of a plasma display, in particular to a method for separately addressing and displaying a three-electrode surface discharge plasma display. Background technique [0002] The Plasma Display Panel (Plasma Display Panel) that uses discharge light has become one of the most competitive products in the display device market with large screen and thin thickness because of its wide viewing angle, large screen, high brightness, and thin thickness. At present, the plasma display needs to be further improved in terms of improving image quality, reducing power consumption, and reducing costs. [0003] The three-electrode surface discharge plasma display has scan electrodes (Y1, Y2, ...Yn), sustain electrodes (X) and address electrodes (A1, A2, ...Am) arranged orthogonally to the scan electrodes and the sustain electrodes. A display unit that can represent red, green, o...

Problems solved by technology

Since there is a large difference in the total number of sustain pulses when displaying a bright image and a dark image, and at the same time, the time between the end of the last subfield of each field and the beginning of the first subfield of the next field is also relatively large, which means The difference in the state of the wall charge in the reset period of the first subfield between displaying a bright image and displaying a dark image is relatively large

If any image is displayed, in order to ensure the correctness of addressing, in the reset period of the first subfield, the driving waveforms of the rising ramp voltage and falling ramp voltage segments with relatively low slopes will be affected, which will affect the brightness of the dark field, thereby affecting the image quality. reduce

In order to simplify the driving circuit, whether the traditional driving method is to display a bright image or a dark image, the first subfield only uses a reset period drive waveform of the same form, while the other subfields use another reset period drive waveform. Difficult to guarantee good image quality when displaying both bright and dark images
