Background technology
LCD has that high image quality, volume are little, in light weight, low voltage drive, low consumpting power and advantage such as have wide range of applications, be widely used in medium and small Portable TV, mobile phone, shoot with video-corder consumer electronics or computer products such as player, notebook, desktop display and projection TV, and (Cathode RayTube CRT) becomes the main flow of display to replace cathode ray tube gradually.Yet, LCD and plasma display panel (Plasma Display Panel, PDP), body such as electroluminescent device, light-emitting diode light emitting display and inequality, display panels itself can't be luminous, be to belong to be subjected to light type display unit, therefore must provide light source to throw light on by the outside and can reach imaging results, so most display panels all is equipped with illuminating backlight overleaf.
The general employed backlight of LCD uses fluorescent lamp as lighting source mostly, and the caliber of fluorescent lamp is between 1.8 millimeters to 2.6 millimeters at present.The structure of fluorescent tube is at the glass tube two ends electrode to be housed, and tube inner wall then scribbles fluorescent material, and envelope has mercury vapor (Mercury) and inert gas (Inert Gas) in the fluorescent tube.To electrode application voltage the time, can produce electronic impact mercury vapor and inert gas, make it transit to excite state.When mercury vapor and inert gas are got back to ground state by excite state, then can emit ultraviolet light, produce visible light to excite the fluorescent material on the tube wall.
When the display area of LCD increases day by day, must use can send white light and even brightness planar light light source.Yet white fluorescent lamp is that line source is not an area source, and therefore the most direct mode is that several fluorescent tubes are contained in the display floater back side.Please refer to Fig. 1, it is a kind of generalized section of known direct-light-type backlight, wherein fluorescent lamp 100 is the back side that is installed in display panels 102 with parallel arrangement mode, reflecting plate (Reflector) 104 is positioned at fluorescent lamp 100 rears, 106 of diffuser plates (Diffuser) are configured between fluorescent lamp 100 and the display floater 102, to reach the effect of area source.
And another kind of line source is converted to the method for area source, and be the end face that fluorescent tube is contained in light guide plate (Louver), reach the effect of area source in edge-lit (Edge Light) mode.Please refer to Fig. 2, is a kind of generalized section of known edge-lit formula backlight, and fluorescent lamp 200 is located at the end face 202a of light guide plate 202, and the light that reflector 204 can send fluorescent lamp 200 is imported in the light guide plate 202 that acryl makes by end face 202a.The front of light guide plate 202 is provided with diffuser plate 206, and the back side and other end face then are covered with reflecting plate 208, can make the light that enters in the light guide plate 202 be its limitation.Light carries out repeatedly total reflection in light guide plate 202, make the whole light guide plate 202 luminous area sources that become, and diffuser plate 206 can make the brightness uniformity of light guide plate.
