Abstract

The utility model relates to a large-size backlight back plate, in particular to a spliced large-size backlight back plate. The spliced large-size backlight back plate comprises a back plate body, the back plate body comprises a bottom plate, an upper support and a lower support which can be spliced, wherein, the bottom plate, the upper support and the lower support are connected and fixed together by a left connecting rod and a right connecting rod, the shapes of the left connecting rod and the right connecting rod are similar, the cross section thereof is in the shape of an opening, and the left connecting rod and the right connecting rod are responsible for connecting the upper and the lower supports and the bottom plate and bearing the weight of a whole product. The spliced large-size backlight back plate has the beneficial effects that the spliced large-size backlight back plate can effectively reduce the weight of the back plate in a large-size backlight product, thereby playing the role of reducing the weight of the whole LCD product, leading a body of the LCD display product to be super-light and super-thin, achieving the effects of leading the product to be lighter and thinner, having compact structure, greatly reducing production cost and saving social resources.

Description

A kind of spliced large scale backboard backlight
Technical field
The utility model relates to a kind of large scale backboard backlight, refers more particularly to a kind of spliced large scale backboard backlight.
Background technology
Along with development of science and technology, be used for being presented in people's daily life of common occurrence with liquid crystal, LCD promptly is the modal liquid crystal displays of people.A complete liquid crystal display product generally includes shell, liquid crystal display module (being LCM), circuit board compositions such as (comprising mainboard and power panel etc.), wherein LCM is an important component part, be responsible for converting the electrical signal to the picture rich in detail that the user sees, (glass is for being commonly called as in the industry by glass for LCM of the prior art, its English by name OPEN CELL) and composition such as backlight, OPEN CELL is the core parts of entire product, the signal of telecommunication can be converted into image pixel, but OPENCELL is not the active display element, must be on pixel by an intense light irradiation, could " photograph " go out abundant picture, provide the task of high light to be finished by backlight, it can provide an intensity uniform area light source for OPEN CELL.
The complete backing structure of large-sized monitor is as shown in Figure 1 by center 40 in the market, backboard 10, optical material 30, light source 20 compositions such as grade, wherein light source 20 is converted into light energy with electric energy, the light energy that optical material 30 is responsible for light source 20 is sent is converted into a uniform surface light source, backboard 10 is structural members important in this product, play and support and fixing all material, center 40 act as optical material and is buckled on the backboard 10, in these materials, because the weight that backboard 10 will be responsible for bearing all material, all must have certain intensity, in traditional design, general backboard all is to be finished by the sheet metal component drawing, so because requirement of strength must have enough thickness greatly, this just causes the weight of backboard self bigger, especially large scale backlight product dorsulum is not sneezed at especially from weight, as the cold rolled plate that is shaped enough thickness must be arranged, and also higher aspect production cost.And in modernized LCD product design trend, think that " ultralight thinning " characteristics of LCD product fuselage will be attracted attention by each side most.
Based on the backboard weak point of above-mentioned existing LCD product, the inventor has designed " a kind of spliced large scale backboard backlight ".
The utility model content
The utility model at above-mentioned the deficiencies in the prior art technical problem to be solved is: a kind of lighter and thinner effect that has is provided, and compact conformation, and can significantly reduce production costs the spliced large scale backboard backlight that economizes on resources.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of spliced large scale backboard backlight, comprise backboard body, described backboard body comprises base plate, upper bracket and the lower carriage that can splice mutually, wherein base plate, upper bracket and lower carriage are connected and fixed with right coupling bar by Left-wing Federation's extension bar and are in the same place, Left-wing Federation's extension bar is similar to right coupling bar shape, the cross section is opening shape, be responsible for connecting and go up lower carriage and base plate, and load-bearing is in the weight of entire product.The backboard of splicing mainly is divided into five big parts, and backboard is made up of four skeletons and base plate.
Described Left-wing Federation extension bar, right coupling bar, upper bracket and lower carriage are finished by the thicker material punching press of thickness, and the power that base plate bears is less, and available thin sheet material processing is assembled together at last again, thus method after changing, mould structure is greatly simplified.And be divided into the little mould of many covers by big mould and finish.And bigger saving is arranged at material.
Described upper bracket and lower carriage cross section are " Z " font.Described base plate cross section is " one " font.Upper bracket, lower carriage and base plate all pass through the riveted joint or screw locking on Left-wing Federation's extension bar and right coupling bar.
Described Left-wing Federation extension bar and right coupling bar cross section are opening shape.
Four thicker material punching presses of skeleton group thickness are finished, and the power that base plate bears is less, and available thin sheet material processing is assembled together at last again, thus method after changing, mould structure is greatly simplified.And be divided into the little mould of many covers by big mould and finish, and aspect material, bigger saving is arranged.
The beneficial effect of a kind of spliced large scale of the utility model backboard backlight is:
In the large scale backlight product, can reduce the weight of backboard effectively, thereby play the purpose that reduces whole LCD product weight, LCD is shown that the product fuselage accomplishes " ultralight thinning ", it is lighter to reach product, thinner effect, and compact conformation, and the production cost that declines to a great extent, save social resources.
