Description
Technical field
This utility model relates to a kind of liquid-crystal displaying screen structure.
Background technology
The LED side back light module unit structure of LCDs mainly has two kinds of forms, and one is direct-type backlight, and one is side backlight, because side backlight type backlight can be easier to be designed as superthin structure, therefore the form of side backlight module gradually develops to the mode of side backlight.Along with LCDs resolution is more and more higher, and brightness of display screen is required more and more higher by user, and original brightness of display screen cannot meet user's requirement, then requires that the requirement improving brightness of display screen is arisen at the historic moment.
From the operation principle of LCDs, in side lamp formula backlight, assume that backlight light extraction efficiency is 100%, it loses 40% in light guide plate, 36% is lost by lower polaroid, by liquid crystal cell loss 18% and surface reflection loss 1%, thus, liquid crystal display from light guide plate to final utilization rate less than 5%.As can be seen here, how light efficiency is improved, how to allow liquid crystal display present a big problem that bright bright-coloured image is liquid crystal display industry.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of under conditions of slimming with cost degradation, can be effectively improved the liquid-crystal displaying screen structure of briliancy and the light source uniformity.
The technical scheme is that this utility model of this utility model includes side backlight module and the light guide plate set gradually from top to bottom, lower polaroid, liquid crystal layer, color film layer, upper polaroid and liquid crystal display layer, it is characterized in that: described liquid-crystal displaying screen structure also includes being arranged on the reflecting plate below described light guide plate, is arranged on the inverse edge eyeglass above described light guide plate and is arranged on the brightness enhancement film layer above described inverse edge eyeglass, and the upper surface of described light guide plate is V-CUT structure.
The lower surface of described light guide plate is distributed the light conductive dot array being made up of some light guiding points, and the upper surface of described reflecting plate is provided with the reflection light point battle array suitable with described light conductive dot array.
Reflection light point in described reflection light point battle array along at described reflecting plate corner to center extend direction on, radius is increasing trend, i.e. the radius of the most remote then pip of distance at described reflecting plate corner is the biggest.
Described liquid crystal display layer is the low temperature polycrystalline silicon display layer (LTPS) that aperture opening ratio is higher.
Described lower polaroid is APCF polaroid.
The direction of the prismatic structure on described light guide plate is oppositely arranged with the direction of the prismatic structure on described inverse edge eyeglass.
nullThe beneficial effects of the utility model are: owing to this utility model includes side backlight module and the light guide plate set gradually from top to bottom、Lower polaroid、Liquid crystal layer、Color film layer、Upper polaroid and liquid crystal display layer，It is characterized in that: described liquid-crystal displaying screen structure also includes being arranged on the reflecting plate below described light guide plate、It is arranged on the inverse edge eyeglass above described light guide plate and is arranged on the brightness enhancement film layer above described inverse edge eyeglass，The upper surface of described light guide plate is V-CUT structure，Compared with prior art，Add brightness enhancement film layer、Reflecting plate and inverse edge eyeglass，And make the structure of described light guide plate vary somewhat，Little to overall thickness effect，And the lifting of cost is limited，And described brightness enhancement film layer can reuse with coordinating of described reflecting plate after absorbed polarized light reflect back originally，The upper V-CUT structure of described inverse edge eyeglass and described light guide plate with the use of，Section makes that scattered light is several goes out light in the range of normal about 70 °，Allow the luminous reflectance more than 70 ° return again be utilized，Utilization rate and the uniformity of light can be improved，So this utility model is under conditions of slimming with cost degradation，Briliancy and the light source uniformity can be effectively improved.
Owing to the lower surface of described light guide plate is distributed the light conductive dot array being made up of some light guiding points, the upper surface of described reflecting plate is provided with the reflection light point battle array suitable with described light conductive dot array, by such structure, not only can reflect light, can effectively improve the uniformity of reflection light, so further improve briliancy and the light source uniformity.

Detailed description of the invention
nullSuch as Fig. 1、Fig. 2、Shown in Fig. 3，Liquid-crystal displaying screen structure described in the utility model includes side backlight module and the light guide plate 2 set gradually from top to bottom、Lower polaroid 6、Liquid crystal layer 7、Color film layer 8、Upper polaroid 9 and liquid crystal display layer 10，Described liquid-crystal displaying screen structure also includes being arranged on the reflecting plate 3 below described light guide plate 2、It is arranged on the inverse edge eyeglass 4 above described light guide plate 2 and is arranged on the brightness enhancement film layer 5 above described inverse edge eyeglass 4，The upper surface of described light guide plate 2 is V-CUT structure，The lower surface of described light guide plate 2 is distributed the light conductive dot array 22 being made up of some light guiding points，The upper surface of described reflecting plate 3 is provided with the reflection light point battle array 31 suitable with described light conductive dot array 22，Reflection light point in described reflection light point battle array 31 along at described reflecting plate 3 four jiaos to center extend direction on，Radius is increasing trend，The i.e. radius of the most remote then pip of distance at described reflecting plate 3 four jiaos is the biggest，These pips not only can reflect light，But also reflection light ratio to be made is more uniform，Described liquid crystal display layer is the low temperature polycrystalline silicon display layer (LTPS) that aperture opening ratio is higher，Described low temperature polycrystalline silicon display layer improves the aperture opening ratio of TFT pixel，Described lower polaroid is APCF polaroid，Described APCF polaroid is the lower surface polaroid with blast sheet APCF，The direction of the prismatic structure 21 on described light guide plate 2 is oppositely arranged with the direction of the prismatic structure 41 on described inverse edge eyeglass 4，Being directed downward of the most described prismatic structure 21，And the direction of described prismatic structure 41 is upward，In addition to can improving briliancy and the light source uniformity，Also can reach slimming and cost degradation，This development is with the inverse edge eyeglass of V-CUT light guide plate collocation Rhizoma Sparganii，High blooming piece (prismatic lens or bright enhancement film) usage amount can be reduced，Brightness 60 can be increased，The effect of described brightness enhancement film layer 5 is by the most absorbed 50% polarized light recycling，This film can allow the first polarized light P1 to pass through，And the second polarized light P2 is reflected recycling and becomes P1 and P2 again，So the most capable of circulation increase brightness.By supporting the use of the most described reflecting plate 3, described brightness enhancement film layer 5, described inverse edge eyeglass 4 and described light guide plate 2 and other film layers, overall brightness can be made to increase by 230%, and structure is the most fairly simple.
