Description
Technical field
This utility model relates to field of liquid crystal display, is specifically related to a kind of Novel straight down type LCD screen.
Background technology
From principle of luminosity, LCD TV (also known as LED-backlit TV, be commonly called as LED television) is by a light source and one
Transparent panel with picture forms.Transparent panel itself will not be luminous, and imaging needs another vital ingredient: the back of the body
Light source.When the picture of transparent panel changes, when light source provides light for it simultaneously, we are it is seen that the most beautiful
Picture.LED liquid crystal television uses LED light as the backlight of TV just, it is provided that stable brightness and color representation.Under Zhi
Formula is that LED luminescent grain is arranged in the rear of liquid crystal panel equably as luminous source, makes backlight to be uniformly communicated to whole
Individual screen, picture detail is the finest and the smoothest true to nature.Its benefit is can be respectively provided with different backlight module power and responsibility regions, in theory
Each LEDs independence light emitting control brightness can be accomplished, but due to Cost Problems, be essentially all the multiple regions of setting, allow this
A little regions independently adjust shading value.
The file of Patent No. CN105278141A discloses a kind of backboard, including surround horn mouth shape side plate and
Connect the base plate of described side plate, from described side plate and described base plate connect the corner formed be convexly equipped with inwardly the described side plate of connection and
The fin of described base plate.The invention also discloses a kind of down straight aphototropism mode set；This device light mixing effect is not outstanding, backlight
Sensing at largest light intensity is directly perpendicular to backlight module.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of Novel straight down type LCD screen, it is to avoid backlight
Largest light intensity at sensing be directly perpendicular to backlight module.
For realizing object above, this utility model is achieved by the following technical programs: a kind of Novel straight down type liquid crystal
Screen, including backlight, diffusion sheet, light source, reflector, housing, described enclosure interior is provided with backlight, and described backlight is
Wavy, the flex point of described backlight curved surface is equipped with light source, described reflector connects backlight surrounding, on described reflector
It is provided with and organizes hole more.
Preferably, described light source is LED light source group.
Preferably, described diffusion sheet is arranged on hull outside, forms airtight cavity with housing.
Preferably, described hole and the LED lamp bead horizontal alignment on light source.
Preferably, described light source is fixed in described backlight by heat-conducting glue.
This utility model provides a kind of Novel straight down type LCD screen, and corrugated backlight avoids the maximum light of light source
The sensing of strength is directly perpendicular to diffusion sheet, improves light mixing distance, makes the marginal position of light source obtain more light and irradiates,
Effectively prevent the high phenomenon causing the uniformity the best of central brightness；Arrange on reflector and organize hole more, can weaken directly
Reflective, it is also possible to play the effect of heat radiation.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is generalized section of the present utility model；
Fig. 2 is top view of the present utility model.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of Novel straight down type LCD screen, including backlight 1, diffusion sheet 2, light source 3, reflector
4, housing 5, described housing 5 is internally installed backlight 1, and described backlight 1 is wavy, the flex point of described backlight 1 curved surface
On be equipped with light source 3, described reflector 4 connects backlight 1 surrounding, and described reflector 4 is provided with many group holes 41.
Described light source 3 is LED light source 3 groups.
It is outside that described diffusion sheet 2 is arranged on housing 5, forms airtight cavity with housing 5.
Described hole 41 and the LED lamp bead horizontal alignment on light source 3.
Described light source 3 is fixed in described backlight 1 by heat-conducting glue.
This utility model provides a kind of Novel straight down type LCD screen, and corrugated backlight avoids the maximum light of light source
The sensing of strength is directly perpendicular to diffusion sheet, improves light mixing distance, makes the marginal position of light source obtain more light and irradiates,
Effectively prevent the high phenomenon causing the uniformity the best of central brightness；Arrange on reflector and organize hole more, can weaken directly
Reflective, it is also possible to play the effect of heat radiation.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although with reference to aforementioned reality
Execute example this utility model has been described in detail, it will be understood by those within the art that: it still can be to front
State the technical scheme described in each embodiment to modify, or wherein portion of techniques feature is carried out equivalent；And these
Amendment or replacement, do not make the essence of appropriate technical solution depart from spirit and the model of this utility model each embodiment technical scheme
Enclose.
