Description
Technical field
The invention relates to a kind of plane modulated structure, and particularly be positioned at the external plane modulated structure of gas discharge chamber relevant for a kind of electrode.
Background technology
Along with industry is flourishing day by day, digitization tools such as mobile phone, digital camera, Digital Video, notebook computer, desktop computer develop towards direction more convenient, multi-functional and attractive in appearance invariably.Yet the display screen of mobile phone, digital camera, Digital Video, notebook computer, desktop computer is indispensable man-machine communication interface, and the display screen by the said goods can bring more facility for user's operation.In recent years, display screen on most mobile phone, digital camera, Digital Video, notebook computer and the desktop computer is a main flow with display panels (LCD panel) all, yet, because display panels itself does not have luminous function, so below display panels, must provide a backlight module (back light module) so that light source to be provided, and then reach the function of demonstration.
Because flat lamp has good illumination efficiency and uniformity, and large-area area source can be provided, so the plane lamp extensively is applied on the backlight even other application of display panels.The plane lamp is a kind of plasma luminescence element, and it mainly is to utilize after electronics penetrates by negative electrode, and the blunt gas between negative electrode and the anode produces collision in the gaseous discharge cavity, and with gas ionization, excite to form plasma.Afterwards, the excite state atom that is excited in the plasma can be got back to ground state to radiate ultraviolet mode, and the fluorophor in the further excitation plane lamp of the ultraviolet ray meeting of being radiated, to produce visible light.
Fig. 1 is the structural representation of known plane lamp.Please refer to Fig. 1, known plane modulated structure is made of gaseous discharge cavity 100, fluorophor 102, discharge gas 104, electrode 106 and dielectric layer 108.Wherein, gaseous discharge cavity 100 is made up of plate-like substrate 100a, plate-like substrate 100b and edge strip 100c, edge strip 100c is disposed between plate-like substrate 100a and the plate-like substrate 100b, and is connected with the edge of plate-like substrate 100a and plate-like substrate 100b, to constitute an airtight cavity.
