Electrical connection.
In the above-described embodiments, by being provided with transparency conducting layer between light guide plate 20 and blooming piece 40, and lead to
Cross the transparency conducting layer to export the electrostatic charge between light guide plate 20 and blooming piece 40, so as to avoid light guide plate 20 and optics
Occur the situation of Electrostatic Absorption between diaphragm 40, improve the buckling phenomena of blooming piece 40, and then improve display device
Display effect.
Understanding to backlight provided in an embodiment of the present invention for convenience, it is former to its structure and work below in conjunction with the accompanying drawings
Reason is described in detail.
As shown in Figures 3 and 4, Fig. 3 is the structural representation of backlight provided in an embodiment of the present invention；Fig. 4 is the present invention
The operating diagram for the backlight that embodiment provides.
As seen from Figure 3, the backboard 10 that is provided in the present embodiment, the structure of light guide plate 20 and blooming piece 40 and set
Putting mode and backlight of the prior art does not have any difference, and therefore, its structure is no longer described in detail.
In the present embodiment, in order to improve the buckling phenomena of blooming piece 40, between light guide plate 20 and blooming piece 40
There is provided layer of transparent conductive layer, and the transparency conducting layer is conductively connected with backboard 10.Light guide plate 20 and blooming piece 40 it
Between when there is electrostatic charge, electrostatic charge is exported on backboard 10 by transparency conducting layer, so as to avoid tabula rasa and optical film
The situation of Electrostatic Absorption between piece 40, in the above-mentioned specific course of work, backboard 10 is as ground, it is achieved thereby that by saturating
The effect that light guide plate 20 is grounded by bright conductive layer.Avoid the charge accumulated on light guide plate 20, so avoid light guide plate 20 with
The situation of Electrostatic Absorption between blooming piece 40, in 40 expanded by heating of blooming piece, due to blooming piece 40 and light guide plate
There is no electrostatic adsorption force between 20, so that blooming piece 40 can smoothly expand, and in expansion, whole optical film piece
40 are extended, therefore, after existing gap need to only meet that blooming piece 40 expands between light guide plate 20 and blooming piece 40
Size when, blooming piece 40 expansion when would not produce fold, so as to improve blooming piece 40 produce fold situation,
And then improve the display effect of display device.
In specific set, transparency conducting layer is coated in the tin indium oxide metal level on light guide plate 20.Tin indium oxide
Metal level has good translucency, and has good electric conductivity, so as to by light guide plate 20 and blooming piece 40 it
Between electric charge export, and the propagation to the light in backlight will not impact.In addition, made using indium tin oxide material saturating
Increase when bright conductive layer reduces production backlight to greatest extent to equipment.Indium tin oxide material is to show in the prior art
The material of substrate manufacture transparency electrode in screen, therefore, shape can be coated on light guide plate 20 using equipment of the prior art
Into transparency conducting layer, without newly increasing new equipment.
When being connected between transparency conducting layer and backboard 10, it can be attached by different conductive structures, it is such as transparent
By being connected between conductive tape 33 and backboard 10 between conductive layer.Or transparency conducting layer passes through electric installation 30 and backboard
10 are conductively connected, and electric installation 30 is when backlight works, control transparency conducting layer and the conductive communication of backboard 10.Preferably, this
The latter connected mode that the backlight that embodiment provides uses.
Specifically, the electric installation 30 includes：The electroconductive elastic sheet 32 being conductively connected with transparency conducting layer；
It is fixed in backboard 10 and is inhaled with the electromagnet 31 of the conductive communication of backboard 10, electromagnet 31 when backlight works
Attached firmly electroconductive elastic sheet 32.
In its specific connection, transparency conducting layer is conductively connected by conductive tape 33 and electroconductive elastic sheet 32, should
Conductive tape 33 or conductive fabric, the both ends of the conductive fabric are connected with electroconductive elastic sheet 32 with transparency conducting layer respectively.No matter
During using conductive tape 33 or conductive fabric, the length of conductive tape 33 or conductive fabric has enough length to ensure conductive bullet
During the motion that piece 32 is adsorbed or separated by electromagnet 31, can ensure the both ends of conductive tape 33 or conductive fabric respectively with it is transparent
Conductive layer and electroconductive elastic sheet 32 are stably connected with.In addition, in order to ensure that electroconductive elastic sheet 32 can return in 31 dead electricity of electromagnet
Initial position, insulation shell fragment 34 is provided between electroconductive elastic sheet 32 and electromagnet 31.When electromagnet 31 is powered, absorption is conductive
Shell fragment 32, the shell fragment 34 that now insulate are compressed；When electromagnet 31 powers off, electromagnet 31 disappears to the absorption affinity of electroconductive elastic sheet 32
Lose, now, in the presence of the restoring force of insulation shell fragment 34, electroconductive elastic sheet 32 returns to initial position.In specific electroconductive elastic sheet
When 32, it can use different structures, preferably, the electroconductive elastic sheet 32 is metal clips.
In above-mentioned specific embodiment, the number of the electric installation 30 can be multiple, and multiple electric installations 30 are set
In the not homonymy of blooming piece 40, so that electric installation 30 is at work, i.e., when electromagnet 31 adsorbs conductive tape 33, lead
Electric adhesive tape 33 is tightened up, and now, passes through the tensioning function of conductive tape 33 so that whole optical film piece 40 is tightened up, so as to keep away
Exempt from conductive tape 33 and the situation of fold occur.
In order to ensure that blooming piece 40 does not produce fold in expanded by heating, i.e., light guide plate 20 and optical film when it expands
Will not produce electrostatic adsorption force between piece 40, the electromagnet 31 that the present embodiment provides obtained when backlight is started working it is electric so that
Electric installation 30 is ensured the electricity between light guide plate 20 and blooming piece 40 before the expanded by heating of blooming piece 40
Lotus exports.And during using said structure, realize backlight not open state when, blooming piece 40 and light guide plate 20 can be because
Electrostatic friction clamping together, jolts during vibration test reliability or transport backlight are carried out to backlight
When, it can effectively avoid causing optical film to scratch with light guide plate 20 partially.
In addition, as a kind of perferred technical scheme, the backlight that the present embodiment provides also includes being arranged on blooming piece
40 layers of vitreous fibre layer 50 between transparency conducting layer.Light guide plate 20 and optics are added by the vitreous fibre layer 50 of setting
The caused quantity of electric charge between diaphragm 40, so that when not starting shooting, the absorption stable with blooming piece 40 of light guide plate 20 is one
Rise, improve and occur situation about scratching between blooming piece 40 and light guide plate 20.And in specific set, vitreous fibre layer 50
It is fixed on 40 layers of one side towards transparency conducting layer of blooming piece.
Present invention also offers a kind of display device, including the backlight described in any of the above-described.
In the above-described embodiments, by being provided with transparency conducting layer between light guide plate 20 and blooming piece 40, and lead to
Cross the transparency conducting layer to export the electrostatic charge between light guide plate 20 and blooming piece 40, so as to avoid light guide plate 20 and optics
