Embodiment
In order more to understand technology contents of the present utility model; especially exemplified by specific embodiment and coordinate appended illustrate as follows; but the following drawings and embodiment are not to restriction of the present utility model; under any, in technical field, have and conventionally know the knowledgeable; not departing from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is when being as the criterion depending on claims person of defining.
Embodiment mono-
Please refer to Fig. 2, the schematic bottom view of the backlight module providing for embodiment mono-, described backlight module comprises backboard 10 and a flexible printed circuit board, and described backboard 10 comprises a spatial accommodation, and described spatial accommodation is provided with a display panels (not shown).Flexible printed circuit board comprises a main part 11 and a signal conducting part 12, and described main part 11 is connected with described display panels, and described signal conducting part 12 is for being connected with external signal.Be provided with a contraposition opening 13 in an edge of backboard 10, the signal conducting part 12 of described flexible printed circuit board is provided with pair of bit lines 14, the position of described opening 13 and pairs of bit line 14 is mutually corresponding, and the width of described opening 13 is consistent at the width at pairs of bit line 14 places with signal conducting part 12.Described pairs of bit line 14 is white silk-screen line.
Then please refer to Fig. 3 is the schematic diagram after the flexible printed circuit board turnover shown in Fig. 2.When flexible printed circuit board is after the bottom surface turnover of backboard 10, pairs of bit line 14 and opening 13 are alignd, signal conducting part 12 is placed in opening 13, contraposition correct position is now described.The signal conducting part 12 of flexible printed circuit board and main part 11 are respectively arranged with double faced adhesive tape 15 and 16 towards the bottom surface of backboard 10 side, use double faced adhesive tape 15 and 16 that flexible printed circuit board and backboard 10 are fixed together.
Because of in the time of contraposition just signal conducting part 12 be placed in opening 13, be highly susceptible to contraposition.In prior art, flexible printed circuit board and backboard are portrayed to line, and be to lean on human eye by two parts contraposition, the backlight module contraposition precision that embodiment mono-provides is higher.
Also be provided with multiple glue frame connecting holes 19 in the edge of backboard 10, when described glue frame connecting hole 19 is used for glue frame and backboard 10 to assemble, glue frame be fastened on to backboard 10 and use when interior.Described opening 13 can form with described glue frame connecting hole 13 in same processing step, in prior art, needs to form and portray line by independent step, and the backlight module that embodiment mono-provides has reduced processing step, has saved cost of manufacture.
Preferably, on described backboard 10, be also provided with multiple auxiliary para openings 18, described auxiliary para opening 18 can with the edge correspondence of the main part of flexible printed circuit board 11, also can with the edge correspondence of signal conducting part 12, when flexible printed circuit board is after the bottom surface turnover of backboard 10, the edge of the edge of main part 11 or signal conducting part 12 and auxiliary para opening 18 are alignd, can further improve the degree of accuracy of contraposition.
Embodiment bis-
Please refer to Fig. 4, the schematic diagram of the backlight module providing for embodiment bis-.As shown in the figure, be with embodiment mono-difference, the two ends of the signal conducting part 22 of flexible printed circuit board have convex shape, and the opening 23 at described backboard 20 edges is also the shape of two ends evagination.Signal conducting part 22 and opening 23 are being carried out contraposition by the above structure
