Abstract
The invention relates to an LED flexible circuit board, belonging to the technical field of semiconductor lighting. The LED flexible circuit board comprises a flexible circuit board, a row of LED light bar comprising LEDs and a light guide plate, wherein the LED light bar is arranged on one side of the flexible circuit board, and an adhesive tape is arranged on the flexible circuit board between two adjacent LEDs. By changing the shape of the adhesive tape and omitting the adhesive tape stuck in front of the light emitting direction an LED light source, the light emitted by the LED can not be blocked, and the brightness of a backlight module can be increased. By comparison, the original brightness of the backlight module is 2800-2900 cd/m<2>, and the increased brightness is 3000-3100 cd/m<2>.
Description
Technical field
The present invention relates to a kind of LED FPC, belong to technical field of semiconductor illumination.
Background technology
Have light emitting diode (Light Emitting Diode, abbreviation LED) flexible print circuit board (Flexible Printed Circuit board is called for short FPC) is widely used on a lot of products such as mobile phone, notebook computer, PDA, digital camera, LCM.On LED lamp bar, post a whole piece adhesive tape before the light emission direction of the lamp source of LED in the prior art, as shown in Figure 2, be used to mount LGP, but adhesive tape there is certain thickness can stop the part light source that the LED light emitting source sends.General adhesive tape thickness is 0.03mm to 0.06mm, for the thick LED of 0.6mm, and 12.5% the light that adhesive tape can shelter from that it sends; For the thick LED of 0.8mm, 5% the light that adhesive tape can shelter from that it sends, brightness of backlight module can be affected like this.
Summary of the invention
Technical problem to be solved by this invention is to overcome defective of the prior art, and a kind of LED lamp bar and LGP syndeton are provided, and reduces stopping of light source that the LED lamp source is sent, reduces the influence to brightness of backlight module.
For solving the problems of the technologies described above, the invention provides a kind of LED lamp bar and LGP syndeton, comprise FPC, and arrange LED lamp bar, the LGP of forming by the LED Light-Emitting Diode, it is characterized in that, one side at described FPC is provided with described LED lamp bar, is provided with adhesive tape on the FPC between the adjacent described LED light emitting diode.
Described adhesive tape one side is pasted with described FPC, and another side and described LGP are pasted.
Described LGP is located at a luminous side of described LED light emitting diode.
Described adhesive tape width is greater than the width of described LED light emitting diode.
The beneficial effect that the present invention reached: by changing the adhesive tape shape, cancellation is attached to the preceding adhesive tape of light emission direction of LED lamp source, the luminous nothing of LED is blocked, can improve brightness of backlight module like this, by contrast, brightness originally is the 2800-2900 briliancy, and brightness of backlight module is the 3000-3100 briliancy after improving.
Description of drawings
Fig. 1 is LED lamp bar of the present invention and LGP syndeton schematic diagram;
Fig. 2 is LED lamp bar and a LGP syndeton schematic diagram in the prior art.
Among the figure, 1, FPC; 2, LED light emitting diode; 3, LGP; 4, adhesive tape; 5, emission side.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, comprise LED lamp bar, LGP 3 that FPC 1, a row are made up of LED Light-Emitting Diode 2 in LED lamp bar of the present invention and the LGP syndeton, one side at FPC 1 is provided with LED lamp bar, on the FPC between the adjacent LED light emitting diode 21, be provided with adhesive tape 4, emission side 5 one sides of LED light emitting diode 2 are not established adhesive tape 4, adhesive tape 4 does not stop the luminous of LED light emitting diode 2, adhesive tape 4 one sides are pasted with FPC 1, and another side and LGP 3 are pasted.LGP 3 is located at the emission side 5 of LED light emitting diode 2.Preferable scheme is the width of adhesive tape 4 width greater than LED light emitting diode 2, so that LGP 3 sticks on the adhesive tape 4 preferably, and does not cover LED light emitting diode 2.
In other embodiments, adhesive tape 4 also can be the other forms of substitute that plays the stickup effect.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
Claims (4)
1. LED lamp bar and LGP syndeton, comprise FPC, and arrange LED lamp bar, the LGP of forming by the LED Light-Emitting Diode, it is characterized in that, one side at described FPC is provided with described LED lamp bar, is provided with adhesive tape on the FPC between the adjacent described LED light emitting diode.
2. according to claim 1 described LED lamp bar and LGP syndeton, it is characterized in that described adhesive tape one side is pasted with described FPC, another side and described LGP are pasted.
