Abstract

The invention discloses a flat fluorescent lamp, which comprises a front glass substrate and a back glass substrate, the inner side of the front glass substrate is provided with a phosphor layer, while the inner side of the back glass substrate is provided with electrodes, a media layer and a phosphor layer. The strip-typed electrodes are divided into two groups and are arranged in parallel, the side of one group of the electrodes is provided with a plurality of processed distributed at regular intervals which positions and seals the front substrate and the back substrate, and then inert gas is filled. The neighboring luminous rows of the invention adopt alternating discharge and the splicing of two groups of alternating discharging regions, reducing or removing the non-luminous region between the neighboring luminous rows and between the neighboring micro-discharge, thus increasing the brightness and the brightness uniformity of the flat lamp.

Description

technical field

[0001] The invention belongs to the field of display and lighting source manufacturing, and relates to a fluorescent lamp, in particular to a plane fluorescent lamp which can be used as a liquid crystal display backlight source and a common lighting source. Background technique

[0002] In recent years, with the further maturity of production technology and the continuous reduction of manufacturing costs, large-screen liquid crystal displays (LCDs) have been more and more widely used. Flat-panel liquid crystal displays with large information capacity are generally transmissive, requiring a light source behind the liquid crystal panel to realize display. At present, the backlight commonly used in flat-panel liquid crystal displays is a cold cathode fluorescent lamp (CCFL), which has the advantages of high light efficiency and brightness, but its disadvantages are that it takes a long time to reach saturated brightness after lighting, and the ignition is greatl...
