[0024] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0025] This application proposes a backlight housing with FPC double-layer alignment lines. Please refer to Figure 1 and Figure 2 , including: at least a pair of double-layer lines 20 and a backlight panel 10. The backlight panel 10 is used for backlighting. Each pair of double-layer lines 20 includes a first alignment line 21 and a second alignment line 22. The first alignment line 21 and the second alignment line 22 are aligned at the head and tail for convenient alignment, and the first alignment line 21 and the second alignment line 22 are arranged in parallel, so that the interval between the first alignment line 21 and the second alignment line 22 is equal everywhere. An FPC 31 fixing area is provided on the backlight panel 10, and the FPC 31 fixing area is used to fix the FPC 31. All the double-layer lines 20 are arranged on the edge of the FPC 31 fixing area. The first alignment line 21 is arranged inside the FPC 31 fixing area, and the second alignment line 22 is arranged outside the FPC 31 fixing area, so that the FPC 31 can be accurately arranged in the FPC 31 fixing area, and the edge of the FPC 31 is aligned and arranged in the interval between the first alignment line 21 and the second alignment line 22, which is convenient for the staff to align the FPC 31 in the FCP fixing area, improves the alignment accuracy of the FPC 31 attached to the backlight panel 10, and further improves the assembly yield rate of other parts in the backlight, thereby improving the production efficiency.

[0026] It should be noted that, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the edge of the FPC 31 is aligned and arranged in the interval between the first alignment line 21 and the second alignment line 22. That is to say, after the FPC 31 is accurately aligned, the FPC 31 covers the first alignment line 21 on the backlight panel 10 and exposes the second alignment line 22. The interval distance between the first alignment line 21 and the second alignment line 22 is short, so that the FPC 31 is regularly arranged in the FPC 31 fixing area, and then the staff fixes the aligned FPC 31.

[0027] Furthermore, the length of the double-layer line 20 is 10 mm.

[0028] Still further, the interval between the first alignment line 21 and the second alignment line 22 is 0.3 mm.

[0029] In an embodiment, please refer to Figure 1 and Figure 2, the number of the double-layer lines 20 is 4 pairs, and every 2 pairs of adjacent double-layer lines 20 form a group. The two groups of double-layer lines 20 are respectively arranged on both sides of the FPC31 fixing area, so that both sides of the FPC31 can be accurately aligned, further improving the attaching accuracy of the FPC31 in the FPC31 fixing area and avoiding interference between the FPC31 and other parts, which may cause product defects.

[0030] In another embodiment, the number of the double-layer lines 20 is 6 pairs. 2 pairs of double-layer lines 20 are parallelly screen-printed above the FPC31 fixing area and symmetrically screen-printed on both sides of the FPC31 fixing area. The remaining every 2 pairs of adjacent double-layer lines 20 form a group, and the two groups of double-layer lines 20 are respectively arranged on both sides below the FPC31 fixing area, so that both the upper and lower sides of the FPC31 can be aligned, further improving the attaching accuracy of the FPC31.

[0031] In one embodiment, please continue to refer to Figure 1 , an FPC binding position 30 is arranged below the backlight panel 10. The backlight housing with FPC double-layer alignment lines further includes an FPC31, and the FPC31 is bound to the FPC binding position 30, and the FPC31 can be electrically connected to the light source in the backlight.

[0032] Furthermore, an avoidance notch 32 is arranged on the FPC31. The design of the avoidance notch 32 is for the assembly of other parts in the backlight. When the FPC31 is bent and attached, it can avoid affecting the setting of other parts, thereby improving the assembly yield.

[0033] It should be noted that the backlight panel is made of iron material, and the double-layer lines are screen-printed on the side of the backlight panel for assembling the light source, that is, the side where the FPC is bent and attached.

[0034] In addition, a clamping frame 33 extends from the edge of the backlight panel 10 on the side where the double-layer lines 20 are arranged, and a plurality of card slots are arranged on the clamping frame 33. The clamping frame 33 and the card slots are clamped with the whole machine housing, so that the backlight panel 10 is detachably connected to the whole machine product, which is convenient for disassembly and maintenance.

[0035] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
