LCD backlight module 021 mainly for liquid crystal panel provide evenly, the light source of high brightness, ultimate principle is by conventional point or linear light sources, changes into high brightness and the area source product of homogeneous briliancy through succinct effectively optical mechanism.General structure is utilize the linear light sources of cold-cathode tube to enter light guide plate through reflex housing, is transformed by line source and is scattered in uniform area source, then does the brightness in order to improve light source through the equal light action of diffusion sheet and the light harvesting of prismatic lens and spend all together.At this, we do simple introduction with regard to several basic comprising assemblies of LCD backlight module 021.
1, light emitting source (Light source): light emitting source must possess the characteristics such as brightness high and life-span is long, there is Cold Cathode Fluorescent pipe (CCFL:Cold cathode fluorescent lamp) at present, hot cathode fluorescent tube, light-emittingdiode (LED:Light emitting diode) and electroluminescence sheet (EL) etc., wherein, cold cathode fluorescent lamp has high briliancy, high-level efficiency, life-span is long, the characteristics such as height is diffractive, add cylindrical outer shape, therefore, be easy to be combined into thin plates lighting device with light reflection element, therefore at present with Cold Cathode Fluorescent pipe for main flow.
2, light guide plate (light guide plate): be applied to side light type backlight module, it is the critical elements affecting optical efficiency, by the method for ejection formation, propylene is suppressed the ganoid wedge shape plate of journey, then apparatus high reflectance and the material of not extinction, stamps circular or square diffusion point at bottom surface of light guide plate screen painting.Light guide plate major function is directing light direction, to improve panel light briliancy and to control brightness uniformity.Cold-cathode tube is positioned at the end face of guide-lighting thickness of slab side, cold-cathode tube issued light enters light guide plate in the mode of end face irradiation, most light utilizes total reflection toward the conduction of thin one end, when light to encounter the injection of microstructure front in bottom surface, utilize density, the micro structured pattern design that varies in size can make light guide plate face uniformly light-emitting.
External form is divided into again: 1, wedge-shaped board; 2, dull and stereotyped.General notebook computer is because considering that spatial relationship all adopts wedge-shaped board, and LCD Monitor and LCD TV then adopts flat board to be main.
3, reflecting plate (Reflector): the reflecting plate of general side-light backlight module is positioned over bottom light guide plate, the light spilt from bottom surface is reflected back in light guide plate, prevent light source from leaking outside, to increase the service efficiency of light: down straight aphototropism mode set is then be placed in lamp box lower surface or paste thereon, will through the light beam of diffuser plate reflection by being again reflected back diffuser plate bottom lamp box to be utilized.
4, diffuser plate (Diffuser): the function of diffuser plate, diffusion sheet is for providing liquid crystal display a uniform area source, generally traditional diffusion barrier is mainly in diffusion barrier base material, add the chemical particle of many, as scattering particle, and its fine particles of existing diffuser plate refers between layer in tree, so light can constantly pass through diffusion layer in the medium that two refractive indexes are different, will be there is many refractions, reflection and the phenomenon of scattering in light at the same time, so just causes the effect that optics spreads.Or use full-figure technique, via chemical programs such as exposure imagings, the phase place branch of frosted glass is recorded alligatoring diffusion barrier substrate surface, with the ink dot in the fuzzy light guide plate of scattering or lines.But under light path framework so, due to the character of material itself and chemical particle, inevasible extinction will be caused, and it is at random to the scattering of light, for the observer of a fixed range, the light intensity having part is wasted, and causes light source effectively to utilize.
5, brightness enhancement film (BEF prismatic lens): after the injection of light self-diffusion plate, the directive property of its light is poor, therefore prismatic lens must be utilized to revise the direction of light, its principle be by light refraction with reflection reach the object of condensing light, improving frontal luminance, to increase the utilization benefit after the injection of light self-diffusion plate, the briliancy of the backlight module of enable entirety improves more than 60%-100%.Mainly with polynary ester (polyester) or polycarbonate (polycarbonate) for material, its surface structure is generally prismatic cylinder or semicylinder.
6, polarisation conversion film (P-S Converter): because in existing LCD design, need that rate is crossed to light source module and fall S-ray directional light, P-ray light source is allowed to pass through, the LCD and the polarization light utilizing this single drives or throws light on, thus produce desired function, so, meeting can first through a Polarizer before light enters liquid crystal panel, this Polarizer can sponge the energy of a certain polarization direction, and the light that cold-cathode tube produces is non-polarization light, when by first Polarizer, luminous energy over half is had to be predominantly absorbed, make the non-constant of the service efficiency of light.Polarisation switch technology must be adopted for addressing this problem, its function makes light source do the conversion of polar biased state, its method be utilize reflecting polarizer layer by by with being separated not by LCD Polarizer, then utilize reflecting plate to convert the light reflected to available polarisation, reach the object that brightness improves.
General polarisation switch technology forms light separating plate by the arrangement mode that special optics is coated with and structure is special, and outgoing is separated into P polarisation and S polarisation, S polarisation becomes again P polarisation after reflection, namely by the Polarizer of LCD; Also a slice cholesterol liquid crystal sheet is utilized to form reflection polarizing plate with quarter wave plate, the emergent light of light guide plate is separated into left-handed and dextrorotation rotatory polarization, left-handed rotatory polarization becomes linear polarization by quarter wave plate Hou, can directly by the first surface Polarizer of LCD, and dextrorotation rotatory polarization is after baffle reflection, also becomes available left-handed polarization and be utilized.
The technology utilizing polarisation to change is to improve the brightness of LCD, and with using the method for prismatic lens to compare, except front face brightness gets a promotion, the brightness in direction also gets a promotion simultaneously with great visual angle, and this is another advantage of polarisation switch technology.
