Embodiment
For the technology contents that the application is disclosed is more detailed and complete, can be with reference to accompanying drawing and following various specific embodiments of the present invention, in accompanying drawing, identical mark represents same or analogous assembly.Yet those of ordinary skill in the art should be appreciated that the embodiment that hereinafter provided is not used for limiting the scope that the present invention is contained.In addition, accompanying drawing, only for being schematically illustrated, is not drawn according to its life size.
With reference to the accompanying drawings, the embodiment of various aspects of the present invention is described in further detail.
Figure 1A illustrates the structural representation with the display panels of shading rubber belt of the prior art, and Figure 1B illustrates the vertical view of the shading rubber belt of Figure 1A.
With reference to Figure 1A, liquid crystal display comprises a Liquid Crystal Module and a backlight module.Wherein, Liquid Crystal Module comprises a colored filter glass substrate (Color Filter Substrate) 101 and one thin-film transistor array base-plate (Thin Film Transistor Array Substrate) 103 being oppositely arranged.Polaroid 201 on one is set above colored filter glass substrate 101, and polaroid 203 is once set below thin-film transistor array base-plate 103.Backlight module at least comprises a light guide plate 300 and multilayer optical film 302, and these optical thin films are positioned at the top of light guide plate 300, can be such as diffusion sheet, brightness enhancement film, reflectance coating etc.
As previously mentioned, in order to prevent occurring rubbing between Liquid Crystal Module and backlight module, avoid the blooming piece of scratch backlight module, conventionally shading rubber belt (Shading Tape) is attached to the edge of Liquid Crystal Module and backlight module, make difficult generation displacement between liquid crystal panel and backlight module.As shown in Figure 1A, shading rubber belt 41 is square ring-type framework, a part for its ring-type framework is attached at the left side edge of the lower surface of the thin-film transistor array base-plate 103 in Liquid Crystal Module, and another part of its ring-type framework is attached at the right side edge of thin-film transistor array base-plate 103 lower surfaces in Liquid Crystal Module.In addition, shading rubber belt 41 also can cover the unnecessary light sending from Liquid Crystal Module edge, in case leak-stopping light.
Yet in Figure 1A, shading rubber belt 41 is smooth in the below of arraying bread board 103, if desired a part for shading rubber belt 41 extended and fit in lower polaroid 203, lower polaroid 203 tends to cause the inside lock place of shading rubber belt 41 to occur interference deformation (as shown in the dotted line frame in Figure 1B), is easy to occur light leak situation.
Fig. 2 A illustrates according to one embodiment of the present invention, has the structural representation of the display panels of shading rubber belt, and Fig. 2 B illustrates the vertical view of the shading rubber belt of Fig. 2 A.
With reference to Fig. 2 A, display panels of the present invention comprises a Liquid Crystal Module and a backlight module.Be similar to Figure 1A, Liquid Crystal Module comprises a colored filter glass substrate (Color Filter Substrate) 501 and one thin-film transistor array base-plate (Thin Film Transistor Array Substrate) 503 being oppositely arranged.Polaroid 601 on one is set above colored filter glass substrate 501, and polaroid 603 is once set below thin-film transistor array base-plate 503.Backlight module at least comprises a light guide plate 700 and multilayer optical film 702, and these optical thin films are positioned at the top of light guide plate 700.
It needs to be noted, display panels of the present invention also comprises a light shielding part 43, the ring-type framework that light shielding part is middle opening, as shown in Figure 2 B.Light shielding part 43 has many line of cut L, by these lines of cut L, light shielding part 43 is divided into a plurality of shading fragments, and at least one shading fragment adheres to the lower surface of the second polaroid 603.Preferably, light shielding part 43 is a square annulus, and line of cut L is positioned at the inside lock place of light shielding part 43.
In certain embodiments, light shielding part 43 is a black and white shading rubber belt.Light shielding part 43 has many line of cut L, and such as Fig. 2 B, four inside lock places of light shielding part 43 are cut open along line of cut L.After four inside lock places of light shielding part 43 being cut by line of cut L, the inner margin portion of light shielding part 43 can be along the peripheral edge portion bending of the relative light shielding part 43 of dotted line shown in Fig. 2 B, and light shielding part 43 is divided into the first shading fragment 431(also referred to as light shielding part outer rim) and the second shading fragment 433(also referred to as light shielding part inner edge) two parts.Further, when four inside lock places of light shielding part 43 are after line of cut L is cut open, the first shading fragment 431 adheres to the lower surface of array base palte 503, and the second shading fragment 433 adheres to the lower surface of the second polaroid 603.
In addition, the second shading fragment 433 of light shielding part 43 can make one termination near or against the border of the effective coverage of display panels, as shown in the vertical dotted line AA of Fig. 2 A.Thus, light shielding part 43 covers the light of liquid crystal panel edge outgoing, thus bright dark inequality and light leak situation in the time of can effectively improving display panels demonstration.
Adopt display panels of the present invention, the second polaroid is arranged at the below of array base palte, light shielding part has many lines of cut (or roulette), by these lines of cut, light shielding part is divided into a plurality of shading fragments, and at least one shading fragment adheres to the lower surface of the second polaroid.Than prior art, light shielding part of the present invention is provided with many lines of cut, thereby light shielding part is easily bent and be attached at the lower surface of array base palte and the lower surface of the second polaroid.In addition, a shading fragment of light shielding part can be attached to the lower surface of the second polaroid and extend the border near the effective coverage of display panels, thereby can significantly improve bright dark inequality or light leak situation.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, without departing from the spirit and scope of the present invention in the situation that, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replacement all drop in the claims in the present invention book limited range.
