Description
Technical field
The relevant a kind of planar light source panel of the utility model, the planar light source panel that particularly relevant a kind of suitable gas discharge mode operates.
Background technology
With reference to Fig. 1, it is the existing planar light source panel construction synoptic diagram that adopts cold-cathode tube.This planar light source panel 100 mainly is to surround in the space that forms at prebasal plate 101 and the metacoxal plate 107 with matrix groove, and one or several cold-cathode tubes that are arranged in parallel 103 are installed; But along with the The Enlargement Tendency of liquid crystal panel, the size of cold-cathode tube 103 also must increase thereupon, has just increased the degree of difficulty on fluorescent tube is made thus.On the other hand, for large-sized liquid crystal panel is provided enough brightness output is arranged, the number of cold-cathode tube 103 just must increase, and the production cost of whole thus planar light source panel 100 improves much just unavoidablely.Moreover, the planar light source panel 100 that adopts several cold-cathode tubes 103 to combine, its common problem can't provide a uniform brightness output exactly, reason is that each root cold-cathode tube 103 its characteristic that is adopted all can't be controlled at identical situation fully, for example different fluorescent tube of half life period will strengthen the difference in its brightness along with the increase of service time, causes exporting brightness situation generation uniformly eventually.
The utility model content
Because in the above-mentioned background technology, relevant planar light source panel adopts the problem that cold-cathode tube produced, the purpose of this utility model provides that a kind of to make assembling simple and can provide enough brightness and uniform in-plane light to export large-scale liquid crystal panel to the planar light source panel of liquid crystal panel adjusted size.
According to above-mentioned purpose, the planar light source panel that the utility model provides, mainly be to be covered with prebasal plate, a metacoxal plate and several barrier ribs of fluorescent layer and to separate out several discharge spaces by one, each discharge space all disposes an electrode pair, and covers one deck dielectric substance layer and another fluorescent layer in regular turn.Then in discharge space, pour into discharge gas afterwards; Thus, when imposing a voltage in electrode pair, then form a cathode electrode and an anode electrode, and excite discharge gas between two electrodes and begin discharge, form the gas discharge state thereby disengage ultraviolet light, and when the fluorescent layer in the ultraviolet light collision discharge space, then can send the visible light of specific wavelength in the fluorescent layer during contained fluorescent substance, stablize and export in the liquid crystal panel from prebasal plate equably.
Adopt said structure, planar light source panel manufacturing assembling of the present utility model is simple and can be with the liquid crystal panel adjusted size, and can provide enough brightness and uniform in-plane light to export large-scale liquid crystal panel to.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
