Description
[technical field]
The utility model relates to a kind of backlight assembly of body side frame, relates in particular to body side frame that a kind of utilization has a groove that holds the fluorescent tube assembly and makes and hold framework, reflecting plate and light guide plate by load and piled up the backlight assembly that the stack assemblies formed and fluorescent tube assembly are fixed.
[background technology]
Along with the fast development of semiconductor technology, various electronic display units require to reach requirement such as light, thin, short, little as far as possible.Especially for example LCD, plasma display panel etc. of flat display more requires resolution height, light, thin etc.Industry is devoted to reduce unnecessary assembly element invariably as far as possible in view of the above.
Liquid crystal indicator has been widely used in desktop computer and notebook computer at present.And liquid crystal display board component in the formation liquid crystal indicator and backlight assembly are to be assembled respectively by different assembling processing procedures, and these assemblies are assembled with each other.Existing backlight assembly, as shown in Figure 1, utilize a shape of the mouth as one speaks upper frame A and load hold framework B with the element of liquid crystal indicator such as reflecting plate, light guide plate, and the fluorescent tube assembly combine.Wherein this shape of the mouth as one speaks upper frame A edge be provided with many snap-fit element a and for be arranged on snap-fit element b that load holds the setting of framework B periphery and block mutually and fixed.But owing to liquid crystal indicator be particular about light, thin make this shape of the mouth as one speaks upper frame must do thinner cause this upper frame framework too soft, be difficult for the complicated and more complicated manufacturing cost that increases of assembling of injection moulding, one-piece construction.And this shape of the mouth as one speaks upper frame is because thin and the soft steadiness that causes is not good.
In addition, United States Patent (USP) 6,502,945B2 disclose a kind of pile up backlight assembly with and assemble method.This patent disclosed pile up backlight assembly comprise a model framework, a reflecting plate, be placed on light guide plate on this reflecting plate, be placed on these anti-both sides of leaded light a pair of fluorescent tube assembling, be placed on diffusion sheet and a pair of upper side frame of this leaded light on anti-, this upper side frame can be contained this light guide plate edge and can be chimeric each other fixing with this model framework.
This United States Patent (USP) mainly is to utilize a L type upper side frame, load to hold framework as supporting framework and in order to make up other elements.But, therefore hold complexity of the chimeric mutually overall construction design that reaches fixing purpose of framework by this upper side frame and load because its upper side frame is the L type.
Moreover, the structure that this United States Patent (USP) disclosed needs assembling from top to bottom in assembling, therefore when assembling this upper side frame will hinder the operator sight line and can't be when assembling whether displacement or damage of inspection lamp pipeline simultaneously, must after assembling is finished, be tested, thereby caused throughput rate decline.In addition, owing to use L type upper side frame in this United States Patent (USP) case, for the hardness that reaches fixing this upper side frame of purpose must reach the certain level that can fix whole assembly, thereby this upper side frame also must tool certain thickness and width, and the visible area of display panels is diminished, or the wider width of its visible area outer rim between the liquid crystal display assembly exterior contour relatively, thereby can't narrow limitization.
Based on the shortcoming of above-mentioned prior art and in order to reach light, thin and stable structure, the utility model people carries out broad research to the liquid crystal indicator structure, thereby finishes the utility model.
[utility model content]
The utility model fundamental purpose provides the body side frame backlight assembly that a kind of assembling is easier and structure is more firm.
Another purpose of the utility model provides that a kind of structure is more simplified and the body side frame backlight assembly of easier manufacturing.
Reach other purposes in order to achieve the above object, the utility model provides a kind of body side frame backlight assembly, and it comprises that holding framework, a reflecting plate and a light guide plate by a load is piled up the stack assemblies of forming; Be arranged on the blooming piece on this stack assemblies; Be arranged on the fluorescent tube assembly of the light guide plate side of corresponding above-mentioned stack assemblies; And have in order to the groove that holds this fluorescent tube assembly and have body side frame, thereby fix this stack assemblies and form backlight assembly with blooming piece in order to the stationary installation of fixing above-mentioned stack assemblies.
