Plasma flat light source structure and liquid crystal indicator
Technical field
The present invention relates to a kind of flat light source structure, and be particularly related to a kind of plasma flat light source structure (plasma flat light source structure) that can be applicable to LCD.
Background technology
Along with industry is flourishing day by day, digitization tools such as mobile phone, digital camera, notebook, desk-top computer develop towards more convenient, greater functionality and direction more attractive in appearance invariably.The display screen of these electronic products is indispensable man-machine communication interfaces, and the display screen of the said goods can be the user and brings more operation convenient.In recent years, the display screen on most mobile phone, digital camera, digital code camera, notebook and the desk-top computer is a main flow with display panels (liquid crystal display panel, LCD panel) all.Yet, because display panels itself do not have luminous function, thus below display panels, must provide backlight module (back light module) so that light source to be provided, and then reach the function of demonstration.
Figure 1A is a kind of structural representation of known plasma flat light source structure.Please refer to Figure 1A, known plasma flat light source structure 10 can be used as backlight module, and this plasma flat light source structure 10 comprises infrabasal plate 11, reflection horizon 12, many strip electrodes line 13, a plurality of dielectric pattern 14, fluorescent material layer (fluorescent material layer) 15, upper substrate 16, sealer (sealant) 17, discharge gas (discharge gas) 18 and a plurality of sept (spacer) 19.Wherein, infrabasal plate 11 has the surrounding zone B of luminous zone A and encirclement luminous zone A.Reflection horizon 12 is arranged at luminous zone A and the surrounding zone B on the infrabasal plate 11, and perforation (through hole) 12a runs through reflection horizon 12 and infrabasal plate 11, and it is in order to the air between the two substrates 11,16 is taken away, inserted inert gas again.Electrode wires 13 is arranged on the infrabasal plate 11, and extends to luminous zone A (not expression Figure 1A) from surrounding zone B.Dielectric pattern 14 is arranged on the infrabasal plate 11, and each dielectric pattern 14 can cover a wherein strip electrode line 13.Fluorescent material layer 15 is arranged on the surface of these dielectric pattern 14 and on the upper substrate 16, and this fluorescent material layer 15 comprises the fluorescent material of ruddiness, green glow, blue light.Sealer 17 is arranged between infrabasal plate 11 and the upper substrate 16, and is positioned at the edge of upper substrate 16 and infrabasal plate 11.Sept 19 is arranged between infrabasal plate 11 and the upper substrate 16.18 of discharge gass are positioned at the space that infrabasal plate 11, upper substrate 16 and sealer 17 are surrounded.
The type of drive of plasma flat light source structure 10 is to apply driving voltage earlier to give electrode wires 13, makes discharge gas 18 be ionized to plasma.Afterwards, in each ion in plasma, the electronics that is in excited state can send ultraviolet ray when getting back to ground state, and when ultraviolet ray that plasma sent shines fluorescent material layer 15, can make the fluorescent material of ruddiness in the fluorescent material layer 15, green glow, blue light send ruddiness, green glow, blue light.After three kinds of light colour mixtures, just form white light.
It should be noted that surrounding zone B master is the contraposition out of true that is used in the compensation manufacture process.Though this surrounding zone B is the luminous dead space of plasma flat light source structure 10, the space of surrounding zone B top also is filled with discharge gas 18.When plasma flat light source structure 10 was driven, the discharge gas 18 that surrounding zone B goes up had the phenomenon that misplaces electricity inevitably.Yet, after discharge gas 18 is ionized to plasma, except emitting ultraviolet ray, also can emit visible light.So, will make plasma flat light source structure 10 regional area (for example edge of plasma flat light source structure 10) emit non-white light, and cause excitation (color purity) variation.
