The embodiment of the present application, contacts in zero clearance in the Y direction by by reflector plate with the diffusion head secret note, so that
Brightness can be prevented unstable, the problems such as bright border.
The embodiment of the present application allows FPC to be connected with backboard by heat-conducting glue, so as to reach quick heat radiating by positive group of lamp bar
Effect.Further, reflector plate (ESR) is attached in shading rubber belt light in part inner face, wherein, ESR is black with diffusion head in the Y direction
Bar is in zero clearance, because attaching ESR in shading rubber belt light in part inner face so that the ESR directly contacts on LED and shading rubber belt,
So as to while FPC quick heat radiating effects are reached, it is thus also avoided that because brightness is a large amount of caused by LED and shading rubber belt directly contact
The generation of the problems such as loss, the unstable uniformity, bright border.
Alternatively, also including the prismatic lens on the light guide plate.
Alternatively, diffusion sheet is also included between the light guide plate and the backboard.
Alternatively, the distance between the light-emitting area of the LED and described FPC edges are in the range of 0~0.12mm.
For example, as shown in Fig. 2 a kind of back light source structure that the embodiment of the present application is provided includes：FPC 1, shading rubber belt 2,
LED 3, heat-conducting glue 10 is attached to shading rubber belt 2 towards the diffusion sheet (ESR) 11 of LED sides, diffusion head secret note 5, prismatic lens
6, light guide plate 7, reflector plate 8, backboard 9, glue frame 14 is attached to the double faced adhesive tape 13 on the inside of glue frame.
At present lamp bar contrary class, i.e. FPC is frequently designed as directly to be contacted with shading rubber belt, but the heat-conducting effect of shading rubber belt
It is far from backboard heat-conducting effect preferable.The application makes FPC be connected with backboard by heat-conducting glue, so as to reach by positive group of lamp bar
The purpose of radiating rate before to quickening lamp.
If as shown in figure 3, only changing lamp bar assembling mode, other designs are without modification, then LED will when lamp bar is just organized
(not shown in Fig. 3, Fig. 3 is only schematic diagram, and actual conditions backlight has when assembling and covers backlight and enter with shading rubber belt directly contact
The action in light portion, can cause LED and shading rubber belt directly contact).Presently used shading rubber belt is nearly all black double faced adhesive tape, institute
If with LED and shading rubber belt directly contact, brightness can be made to lose significantly；Also, because shading rubber belt and LED are perpendicular to the back of the body
There is certain gap (gap) on the direction of plate (in abbreviation Z-direction), in an assembling process, pressure head portion in z-direction so that LED
With shading rubber belt directly contact, firmly large and small grade during portion of not pressure head portion, or pressure head can all have influence on the overall uniform of backlight
Degree.And light can directly reach the edge that adds lustre to by this gap, cause the possibility of bright border, wherein, the line with arrow in Fig. 3 is represented
The light that LED sends.
In the embodiment of the present application, while positive group of lamp bar is reached into quick heat radiating effect, to avoid LED and shading rubber belt
Directly contact, ESR (in Fig. 2 11) is attached in shading rubber belt inner face, and ESR is in the direction (abbreviation Y-direction) parallel to backboard
Upper and diffusion head secret note (in Fig. 2 5) is in zero clearance.Make LED and ESR directly contacts, because ESR has the work of reflection light
With the light that LED sends can reflect again after reaching reflector plate, light is utilized rather than being absorbed, so as to avoid
Luminance loss, the uniformity is unstable, generation the problems such as bright border.
In addition, by FPC double faced adhesive tapes come lightguide plate fixing more than current general design, and in the embodiment of the present application, because will
Positive group of lamp bar, LED light-emitting areas need to be controlled within 0~0.12mm away from FPC edges preset space, can for example reserve 0.05mm away from
From, the 0.05mm embodied in Fig. 2, is both the distance of LED light-emitting areas and FPC edges, be also LED light-emitting areas and light guide plate away from
From, therefore can not specifically have two reasons with the method come lightguide plate fixing, a reason is that adhesive tape can be worked into the industry at present
Minimum widith is 0.35mm, and the additional width of FPC at most only has 0.12mm, so unavailable；Second reason is, if adopting
With lamp glue lightguide plate fixing, in order to ensure planarization, light guide plate needs to be stepped down for lamp glue in thickness direction so that light guide plate light
Do not allow disposable.Therefore, in the embodiment of the present application, in glue frame light out part (in Fig. 2 circles) inner side attaching double faced adhesive tape (in Fig. 2
13), during assembling light guiding plate by light out part assemble, lightguide plate fixing is carried out in this approach.
