Abstract

The invention discloses a kind of tempered glass to cover the backlight module that copper realizes electrical connection, including tempered glass, and is cascadingly set on positive first insulating layer of tempered glass, the first copper clad layers, the first backlight assembly.DLED low and middle-end television set is cancelled tradition, single iron backboard, is reduced the investment of mold, low and middle-end television set is made also to have class using tempered glass as the television set of the entire mould group of back plate support;Copper is covered in glass back plate realizes electrical connectivity, directly back light device (LED lamp bead and lens) and other components are fixed in glass back plate, tempering backboard is allowed to become a component with lamp bar, and only need to spread plate bracing frame and optical diaphragm when producing line assembling on this component just at a backlight module, improve production efficiency.

Description

A kind of tempered glass covers the backlight module of copper realization electrical connection

Technical field

The present invention relates to field of television, especially a kind of tempered glass covers the backlight module that copper realizes electrical connection.

Background technique

With the continuous development of television set, LG, Skyworth, Changhong, a line television set brand enterprise such as Konka be successively proposed Using tempered glass as the television set of the entire mould group of back plate support, and not only appearance looks elegant, intensity are reliable for tempered glass, also simultaneously The die sinking expense for eliminating hardware backboard, reduces costs, for this purpose, being a kind of using tempered glass as the entire mould group of back plate support Industrial trend.However the release of the television set brand of these lines is using tempered glass as the entire ELED mould group of back plate support High-end television sets, and stop continuing because of the problem of positioning of lamp bar difficulty will lead to reliability as the low and middle-end television set of DLED Research and development.

Tempered glass 1 is now used as the backlight product of structural support, requires in addition to use LED light bar as backlight light Source, LED light bar mainly by: pcb board 2 and LED lamp bead 3, lens 4 constitute (as shown in Figure 1);Single double-sided PCB board structure is by substrate 5, glass-fiber-fabric 6 (or other insulation adhesion material matter), copper foil 7 (as shown in Figure 2 and Figure 3);

For example the backlight of low and middle-end television set using LED light bar, there is difficult positioning in LED light bar on tempered glass The problem of will lead to reliability.It is in particular in following: being consolidated lamp bar using glue or gummed paper in backlight module production process Determine onto tempered glass backboard, be easy to scratch glass back plate in operation process to lead to light leakage, glue or gummed paper improper use are held Lamp bar out-of-flatness and reliability are easily led to there are problem, during pasting lamp bar glue or gummed paper moved before not being fully cured or Mobile in operation process to be easy to drive lamp bar displacement, the activity duration is long and production difficulty is big, production efficiency and yield are low.

Summary of the invention

In order to solve the above technical problems, the object of the present invention is to provide a kind of tempered glass to cover the back that copper realizes electrical connection Optical mode group, tempered glass backboard are combined into one with pcb board, save lamp bar packaging technology, are greatly improved production efficiency and yield, are gone Except the original substrate of PCB saves material cost.

The technical solution adopted by the present invention is that:

A kind of tempered glass covers the backlight module of copper realization electrical connection, including tempered glass, and is cascading In positive first insulating layer of tempered glass, the first copper clad layers, the first backlight assembly.

The tempered glass, which covers copper, realizes that the backlight module of electrical connection further includes being cascadingly set on tempered glass back The second insulating layer in face, second copper-clad layer, the second backlight assembly.

First insulating layer, second insulating layer are all glass-fiber-fabric.

First copper clad layers, second copper-clad layer are all copper foil.

First backlight assembly includes back light device and appliance component, and the back light device includes LED lamp bead and lens, the LED lamp bead are connected electrically in the first copper clad layers, and light distribution is arranged in LED lamp bead in lens.

First backlight assembly, the second backlight assembly all include back light device and appliance component, described Back light device includes LED lamp bead and lens, which is respectively electrically connected to the first copper clad layers, on second copper-clad layer, thoroughly Light distribution is arranged in LED lamp bead in mirror.

Beneficial effects of the present invention:

1, DLED low and middle-end television set cancels tradition, list using tempered glass as the television set of the entire mould group of back plate support One iron backboard, reduces the investment of mold, and low and middle-end television set is made also to have class;

2, cover copper in glass back plate and realize electrical connectivity, directly by back light device (LED lamp bead and lens) and Other components are fixed in glass back plate, and tempering backboard is allowed to become a component with lamp bar, and are only needed when producing line assembling Plate bracing frame and optical diaphragm will be spread on this component just at a backlight module, improve production efficiency.

Detailed description of the invention

A specific embodiment of the invention is described further with reference to the accompanying drawing.

Fig. 1 is the structural schematic diagram of traditional backlight module;

Fig. 2 is the structural schematic diagram of traditional single side PCB;

Fig. 3 is the structural schematic diagram of the two-sided PCB of tradition;

Fig. 4 is the structural schematic diagram of single side tempered glass of the present invention;

Fig. 5 is the structural schematic diagram of the two-sided tempered glass of the present invention;

Fig. 6 is the structural schematic diagram of backlight module of the present invention.

Specific embodiment

As shown in figure 4, being single side tempered glass of the invention, including tempered glass 11, and it is cascadingly set on steel Change positive first insulating layer 12 of glass 11, the first copper clad layers 13.

As shown in figure 5, being two-sided tempered glass of the invention, including tempered glass 11, and it is cascadingly set on steel Change positive first insulating layer 12 of glass 11, the first copper clad layers 13, and is cascadingly set on the of 11 back side of tempered glass Two insulating layers 14, second copper-clad layer 15, the second backlight assembly.

Wherein, preferably described first insulating layer 12, second insulating layer 14 are all glass-fiber-fabric.It can certainly be that other are existing Known insulating materials;In addition, first copper clad layers 13, second copper-clad layer 15 are all copper foil.

As shown in fig. 6, covering the backlight module that copper realizes electrical connection, including earlier figures for a kind of tempered glass of the invention 4 single side tempered glass and the first backlight assembly, first backlight assembly include back light device and electric appliance member Device, the back light device include LED lamp bead 16 and lens 17, which is connected electrically in the first copper clad layers 13, Light distribution is arranged in LED lamp bead 16 in lens 17.
