Abstract
The utility model relates to a flexible circuit board structure of a back light source, which comprises a flexible circuit board body, wherein LED light-emitting components are arranged on the flexible circuit board body respectively; and the flexible circuit board structure is characterized in that black paint is brushed onto the flexible circuit board body and at the parts corresponding to the luminous surfaces of the LED light-emitting components. Compared with the prior art, the flexible circuit board structure has the advantages that the black paint is brushed onto the flexible circuit board body and at the parts corresponding to the luminous surfaces of the LED light-emitting component, and the black paint in front of the lamp has the light shielding effect and can prevent part of light, so that the phenomenon of bright spots due to the excessively short distance between the LED light-emitting components and the glass screen can be avoided, and the visual effect of the back light source is further ensured.
Description
Technical field
The utility model relates to a kind of flexible circuit plate structure of backlight.
Background technology
The main effect of backlight is to provide light source for other electronic products such as mobile phones.The general flexible PCB that posts the LED light-emitting component that adopts of the backlight of electronic products such as existing mobile phone, flexible PCB is general whole white lacquers at the position of not pasting the LED light-emitting component.When the distance between the glass visual screen of electronic products such as LED light-emitting component on the flexible PCB and mobile phone during in the 3.0mm left and right sides, backlight can not produce speck, but the distance between the glass visual screen of electronic products such as LED light-emitting component on the flexible PCB and mobile phone is when 2.5mm is following, backlight will produce speck, thereby influence the visual effect of complete machine, along with electronic product complete machines such as mobile phone are done littler and littler, to do thinner and thinner, traditional backlight can't meet the demands again.
The utility model content
Technical problem to be solved in the utility model is to provide distance between a kind of LED light-emitting component and the glass visual screen can not produce the flexible circuit plate structure of the backlight of speck when 2.5mm is following at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the flexible circuit plate structure of this backlight, it comprises the flexible PCB body, this flexible PCB body is provided with the LED light-emitting component, it is characterized in that: be brushed with pitch-dark with the corresponding position of the light-emitting area of described LED light-emitting component on the described flexible PCB body.
As improvement, the vertical range between the described pitch-dark and described LED light-emitting component is 1.1mm～1.3mm.
Improve, described flexible PCB body is provided with the plurality of LEDs light-emitting component again, and all to brush length with the corresponding position of the light-emitting area of described every LEDs light-emitting component on the described flexible PCB body be 4mm～5mm, and width is the pitch-dark of 0.4mm～0.6mm.
Compared with prior art, advantage of the present utility model is: by pitch-dark with the corresponding position of the light-emitting area of LED light-emitting component brush on the flexible PCB body, the pitch-dark effect that shading is arranged before the lamp, can shield portions light, thereby can prevent, thereby guarantee the visual effect of backlight because of but the LED light-emitting component too closely causes the generation of speck apart from the glass screen.
Description of drawings
Fig. 1 is the flexible PCB structural representation of backlight among the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The flexible circuit plate structure of backlight as shown in Figure 1, it comprises flexible PCB body 1, this flexible PCB body 1 is provided with plurality of LEDs light-emitting component 2, present embodiment is in order to set forth conveniently, with five LEDs light-emitting components 2 is example, this state on the flexible PCB body 1 with the corresponding position of the light-emitting area of every LEDs light-emitting component 2 all be brushed with length be 4.5mm, width be 0.5 pitch-dark 3, the vertical range d between every pitch-dark 3 and its corresponding LED light-emitting component is 1.2mm.
