First, the set voltage is applied simultaneously to all the pixels and their individual cells. Next, the pixels are addressed one line at a time. Each line is selected in turn and the pixel cells along that line are addressed individually by the digitised video data fed down the address electrode bus. If a particular cell in that line is to be selected for discharge, then the dielectric in that cell is charged and a wall charge is formed. Once the pixel cells have been addressed and the appropriate cells primed by a wall charge, the next line is selected and the cells in that line are addressed and primed as dictated by the next set of video data clocked down the address columns and so on.  <\/p>\n<p align=\"justify\">When all the lines have been scanned and all the pixel cells addressed and primed as necessary, the sustain phase is then executed by applying a series of sustain pulses to all S electrodes and a similar but anti-phase  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-GBzaf9YaVlU\/VeHYWjj-kYI\/AAAAAAAB4II\/tF-aKXEfhhY\/s1600-h\/Plasma-panels-06022.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Plasma panels-0602\" border=\"0\" alt=\"Plasma panels-0602\" src=\"http:\/\/lh3.googleusercontent.com\/-PXs6sqOYXjU\/VeHY7rTxZPI\/AAAAAAAB4JI\/fxM0G_ufDaM\/Plasma-panels-0602_thumb.jpg?imgmax=800\" width=\"349\" height=\"223\" \/><\/a>  <\/p>\n<p align=\"justify\">sustain pulses to the common C electrodes. The scan and sustain wave- forms will thus have the distinctive shapes shown in Figure 10.12. A set voltage pulse <i>V<\/i>S is applied to all scan electrodes simultaneously to clear and set all pixel cells. This is then followed by the address or write period in which, each line or row of pixels is selected in turn by a negative going select pulse. The cells along the selected line are then addressed and primed by one-bit video data fed down the address bus, hence the name <i>one-bit plane <\/i>technique. A video data bit of 1 will select the cell for emission and a wall charge will be formed. A data bit of 0 will not select the cell and wall charge will not be formed. After the line has been addressed, its scan voltage is kept at a negative voltage known as <i>base-write <\/i>voltage <i>V<\/i>BW for the remaining duration of the address period. This is necessary in order to avoid pre-mature discharge of the cells, known as <i>self-erasing <\/i>discharge which will remove the wall charge. As for the sustain electrode, it is kept at a small negative voltage known as <i>sub-write <\/i>voltage <i>V<\/i>SW during the address period. At the end of the address period, out-of-phases 4\u20135 Jls pulses are fed into the sustain and scan electrodes for the simultaneous discharge and display of all selected pixel cells.  <\/p><div class=\"fkgvn6a0dbc3e8fa57\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 television-and-video -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"6549443290\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.fkgvn6a0dbc3e8fa57 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.fkgvn6a0dbc3e8fa57 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.fkgvn6a0dbc3e8fa57 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.fkgvn6a0dbc3e8fa57 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.fkgvn6a0dbc3e8fa57 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"vqvne6a0dbc3e8f9b3\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.vqvne6a0dbc3e8f9b3 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.vqvne6a0dbc3e8f9b3 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.vqvne6a0dbc3e8f9b3 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.vqvne6a0dbc3e8f9b3 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.vqvne6a0dbc3e8f9b3 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\">Figure 10.13b shows the waveforms associated with addressing three pixel cells, KN, LN and MN on three consecutive lines, YK, YL and YM respec- tively. All three cells fall along the same address line An (Figure 10.13a). At the set phase, a set pulse is fed to all scan lines. The address phase involves selecting each line separately by a negative going pulse. Pixel line YK is selected by YK select pulse and at the same time, data for pixel cell Kn appears on address line An to prime the cell for discharge during the sus- tain phase. Pixel line YL is then selected by YL select and simultaneously data Ln appears on address bus An to prime the cell.
