Gas discharge tube and drive method therefor |
摘要 |
<p>Disclosed are a gas discharge tube used for the backlight of a liquid crystal display (LCD) or the like and a drive method for the same. A flat type gas discharge tube comprises two plane glasses, a barrier and at least one electrode group comprised of a plurality of parallel electrodes. Voltages are applied to each electrode group in one discharge period in such a way that discharges of a rare gas dispersed spatially and along the time are allowed to occur. Even when a single gas discharge tube is used for the backlight of an LCD having a large display area, therefore, it does not suffer luminance unevenness and the locations of discharge can be dispersed spatially and along the time, thus ensuring a high emission efficiency. As the backlight does not require a light guide plate or a diffusion sheet, its manufacturing cost becomes lower.</p> |
