AI Technical Summary
In the existing FPC lamp panels, the spacing between LEDs causes light to not directly enter the light guide plate, forming a difference in light intensity in bright and dark areas, resulting in poor lighting shadows.
The copper clad area is arranged on the back of the FPC lamp plate and coated with a rolled copper material. The air-evacuation area is set on the front to display the color of the rolled copper material, thereby absorbing the light from the light emitting components and reducing the difference in light intensity.
By reducing the difference in light intensity, the effect of the lamp shadow is improved, so that the direct area of the light emitting component is close to the light intensity of the light ray entering the light guide plate next to the shadow area, achieving the effect of improving the lamp shadow.

[0033] Example
[0034] In the relevant context, there is a certain interval between the LEDs welded on the FPC light board in the backlight module, and the LED light-emitting angle is limited. There will be an area between the two LEDs where light cannot directly enter the light guide plate. Only light reflected by the white silk screen on the surface of the FPC and the reflective film can enter the light guide plate in this area. Therefore, the light intensity is weak, forming a darker area at the edge of the light guide plate. Directly opposite the LED, light directly enters the light guide plate, and light reflected by the white silk screen on the surface of the FPC and the reflective film enters at the same time, forming a bright spot in this area at the edge of the light guide plate.
[0035] In view of this, if Figure 1-Figure 3 As shown, in the first aspect, an embodiment of the present application provides an FPC lamp board, comprising: a lamp board body 100, the lamp board body 100 comprising a relatively distributed front and back side, the back side being provided with a copper clad area 101, the copper clad area 101 being configured for coating a rolled copper material, the front side being connected to a light emitting component 200, and the front side being provided with an air avoidance area 102, the air avoidance area 102 being located in front of the light emitting direction of the light emitting component 200, and the air avoidance area 102 being used for displaying part of the rolled copper material.
[0036] Exemplarily, the rolled copper material is a material with glue pressed on both sides. The appearance characteristic of this material is that the rolled copper material (i.e., copper coating) on the back side appears black when observed through the front side avoidance area 102. By utilizing this characteristic, a black area (i.e., the position of the side avoidance area 102) can be formed in front of the light-emitting component 200 of the lamp panel body 100.
[0037] It should be noted that the light-emitting component 200 includes but is not limited to LED (Light-Emitting Diode). The light-emitting component 200 can be fixed to the front of the lamp board body 100 by welding, and the number of the light-emitting components 200 is not specifically limited and can be set according to actual conditions.
[0038] In the above-mentioned implementation process, the back copper-clad area 101 of the lamp board body 100 is coated with rolled copper material, and the front side is provided with an air-avoiding area 102 for displaying the rolled copper material, so that after the light-emitting component 200 is welded to the front side of the lamp board body 100, the light emitted by the light-emitting component 200 can be absorbed by the air-avoiding area 102, thereby making the light intensity of the direct area of the light-emitting component 200 and the adjacent dark shadow area entering the light guide plate 300 close, thereby achieving the effect of improving the lamp shadow.
[0039] like Figure 1 As shown, the copper-clad area 101 is distributed along the length direction of the light board body 100, for example, the copper-clad area 101 is configured in a square shape, and the length direction includes but is not limited to the left and right direction. The front air-avoiding area 102 of the light board body 100 can display the color of the rolled copper material, which is conducive to absorbing the light of the light-emitting component 200, so that the light intensity of the direct area of the light-emitting component 200 and the shadow area next to it entering the light guide plate 300 is close, achieving the effect of improving the light shadow.
[0040] like Figure 2As shown, the avoidance area 102 is configured with an arc segment, and the arc segment is convex along the direction close to the light-emitting component 200, that is, the side of the avoidance area 102 close to the light-emitting component 200 is convex, and the convex curvature can be set according to actual conditions.
[0041] In the above implementation process, by setting the air avoidance area 102 as an arc segment, the light intensity of the direct area of the light-emitting component 200 and the adjacent dark shadow area entering the light guide plate 300 can be close, thereby achieving the effect of improving the light shadow without modifying the structure or adding other additional materials. It has good applicability and portability, and can save product development costs.
[0042] In some embodiments, the air avoidance area 102 is located directly in front of the light emitting component 200 .
[0043] In the above-mentioned implementation process, it is beneficial to absorb the light of the light-emitting component 200, so that the light intensity of the direct area and the shadow area of the light-emitting component 200 entering the light guide plate 300 is close, thereby achieving the effect of improving the light shadow. There is no need to modify the structure or add other additional materials. It has good applicability and portability, and can save product development costs.
[0044] In some embodiments, the number of the air-avoiding regions 102 is consistent with the number of the light-emitting components 200, and the center of the air-avoiding region 102 and the center of the light-emitting component 200 are located on the same vertical line, for example, the air-avoiding regions 102 and the light-emitting components 200 are each configured with two, the two light-emitting components 200 are spaced apart, and one air-avoiding region 102 is configured directly in front of each light-emitting component 200. This is beneficial to improving the effect of light shadow, has good applicability and mobility, and saves product development costs.
[0045] In some embodiments, the front side is further configured with a printing area 103, and the printing area 103 is located outside the air avoidance area 102, and the printing area 103 is used for screen printing white ink.
[0046] In the above implementation process, by setting a printing area 103 printed with white ink on the front, the air avoidance area 102 displays the color of the rolled copper material in front of the light-emitting component 200, which is beneficial to the light absorption of the light-emitting component 200, thereby improving the light shadow effect.
[0047] In some embodiments, the light board body 100 further includes a circuit, and the circuit does not pass through the air-avoiding area 102 , so as to avoid the circuit from interfering with the air-avoiding area 102 , thereby affecting the light absorption of the light-emitting component 200 .
[0048] like Figure 3As shown, in a second aspect, the present application further provides a backlight module, including: a light guide plate 300; and the FPC light board as described above, wherein the light guide plate 300 is connected to the FPC light board.
[0049] In the above implementation process, the FPC lamp board is configured with a copper-clad area 101 and an air-avoiding area 102, so that when the light-emitting component 200 on the FPC lamp board emits light, it can ensure that the light intensity entering the light guide plate 300 from the direct area of the light-emitting component 200 and the adjacent dark shadow area is close, which is beneficial to improving the lamp shadow problem without modifying the structure or adding other additional materials. It has good applicability and portability, and can save product development costs.
[0050] In some embodiments, the backlight module further includes a reflective film 400 , and the reflective film 400 is stacked on the light guide plate 300 and the light-emitting component 200 of the FPC light board.
[0051] In a third aspect, the present application further provides an electronic device, comprising the backlight module as described above. Exemplarily, the electronic device may be a liquid crystal display module, including a liquid crystal television, a liquid crystal tablet, a liquid crystal panel, and a mobile phone.
[0052] Since the electronic device provided in the third aspect includes a backlight module, the electronic device has all the technical effects of the backlight module, which will not be described in detail here.
[0053] In all the embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms are not elaborated in the embodiments of the present application.
