Detailed Description
The related technical contents of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before proceeding with the detailed description, it should be noted that similar elements are denoted by the same reference numerals.
Referring to fig. 1, a backlight module according to a preferred embodiment of the present invention includes a frame 2, a plurality of light emitting elements 5 disposed in the frame 2, and an optical unit 7 disposed on the frame 2 for emitting light. The optical unit 7 may be a combination of a light guide plate, a light guide film and/or a plurality of optical films as required.
The frame 2 is formed by bending the flexible circuit board 3, and the flexible circuit board 3 includes a central region 31, a sidewall region 32 extending from the periphery of the central region 31, and a connection region 33 extending from the sidewall region 32 to form an electrical connection with an external device (not shown). The light emitting members 5 are disposed at intervals in the central region 31 of the foldable circuit board 3.
Fig. 2 shows one way of shaping the frame 2: the frame 2 is formed by directly stamping the bendable circuit board 3, so that the sidewall area 32 has a first sidewall portion 321 integrally bent and extended from the periphery of the central area 31, and a second sidewall portion 322 integrally bent from the first sidewall portion 321 and outwardly extended toward a direction away from the central area 31.
Fig. 3 shows another way of shaping the frame 2: the frame 2 is formed by bending and fixing the bendable circuit board 3, so that the sidewall 32 has four bending sections 323 extending radially outward from the edge of the central section 31, each bending section 323 has an inner bending portion 324 connected to the central section 31, an outer bending portion 325 connected to the end of the inner bending portion 324, a valley fold line for separating the central section 31 and the inner bending portion 324, and a mountain fold line for separating the inner bending portion 324 and the outer bending portion 325. It should be noted that the dotted line where the short line and the point are sequentially connected in series represents a VALLEY broken line (VALLEY FOLD line), that is, the VALLEY FOLD line is bent upward along the VALLEY broken line, and the VALLEY broken line is in an inward concave state after being bent; the dotted line formed by connecting a plurality of short lines of equal length in series represents a MOUNTAIN FOLD line (MOUNTAIN FOLD), i.e., a MOUNTAIN FOLD line bent downward, which is exposed and protruded after being bent. The four inner bending portions 324 are bent along valley fold lines and then connected together to form the first sidewall portion 321 shown in fig. 2, and the four outer bending portions 325 are bent along mountain fold lines and then connected together to form the second sidewall portion 322 shown in fig. 2. In addition, it should be noted that the valley fold line and the mountain fold line are illustrated for explaining the bending manner of the embodiment, and the valley fold line and the mountain fold line may not be displayed on the bendable circuit board 3 actually. In the preferred embodiment of the present invention, after two adjacent bending sections 323 in the four bending sections 323 of the sidewall area 32 are bent, preferably, the adjacent inner bending portions 324 contact each other and the adjacent outer bending portions 325 contact each other, so that the two bending sections can support each other with better supporting strength. However, it is also possible that adjacent inner folds 324 or adjacent outer folds 325 are not completely joined to form a continuous sidewall region 32, depending on the requirements of different products.
In addition, referring to fig. 4, the frame 2 further includes four reinforcing sheets 4, which are used in cooperation with the bendable circuit board 3 formed by bending. After the bendable circuit board 3 is bent, the two ends of the reinforcing sheet 4 are respectively combined with the two adjacent bending sections 323, that is, combined with the corner positions of the bendable circuit board 3, so as to fix the shape of the bendable circuit board 3 and enhance the strength of the whole structure of the bendable circuit board 3. The reinforcing sheet 4 may be bonded in several ways.
First, as shown in fig. 4, the reinforcing sheet 4 is a separate element, which is directly bonded to the inner bending portion 324 of two adjacent bending sections 323 by means of adhesion or nailing.
In a second way, as shown in fig. 5, a through hole 320 is formed on each inner bending portion 324, and each reinforcing sheet 4 is an independent element and has a body section 41, two neck sections 42 connected to two ends of the body section 41 respectively and having a width smaller than that of the body section 41, and two connecting sections 43 connected to ends of the two neck sections 42 respectively and having a maximum width larger than that of the two neck sections 42, and the maximum width of each connecting section 43 is larger than that of each through hole 320. After each reinforcing plate 4 is bent at an angle close to a right angle, two connecting sections 43 are inserted into the through holes 320 of two adjacent inner bent portions 324, respectively. Because the reinforcing sheet 4 has slight flexibility, the connecting sections 43 can be slightly bent to pass through the through holes 320 and then return to the original shape when passing through the corresponding through holes 320, and the connecting sections 43 can be clamped without falling off after passing through the corresponding through holes 320 by virtue of the structural design that the maximum width of each connecting section 43 is greater than the width of each through hole 320, so as to form the connecting mode shown in fig. 6.
In a third mode, as shown in fig. 7, the reinforcing plate 4 directly extends from the ends of the inner bending portions 324 to the outside, and has a body section 41 connected to the inner bending portions 324, a neck section 42 connected to the body section 41 and having a width smaller than that of the body section 41, and a connecting section 43 connected to the end of the neck section 42 and having a maximum width larger than that of the neck section 42, and the other end of the inner bending portions 324 is formed with a through hole 320. That is, in the present embodiment, one end of each of the inner bending portions 324 has a reinforcing member, and the other end has a through hole 320. Wherein the maximum width of the coupling section 43 of each reinforcing sheet 4 is greater than the width of each through-hole 320. Therefore, each reinforcing sheet 4 is not detached after being bent by inserting the coupling section 43 into the through hole 320 of the adjacent inner bent portion 324. The three fixing methods of the bending circuit board 3 can all achieve the effect of enhancing the structural strength of the frame 2. The fastening method of the sheet-shaped reinforcing sheet 4 selected in the second and third fixing methods can also achieve a narrow frame effect of reducing the frame thickness. In addition, the reinforcing sheet 4 directly extending from the bendable circuit board 3 only needs to be aligned with the hole site once by the assembler in the installation process, thereby simplifying the assembly procedure and shortening the assembly time.
In addition, the optical unit 7 may be provided in two ways. In a first arrangement, as shown in fig. 8, the optical unit 7 is located on the light emitting side of the light emitting element 5 by the support and positioning of the sidewall region 32, so that the light mixing distance can be increased. In addition, when the outer bent portions 325 of the sidewall regions 32 are used to support the outer periphery of the optical unit 7, the contact area between the outer bent portions 325 and the optical unit 7 is large, so that the optical unit 7 can be fixed on the frame 2 by applying adhesive, thereby improving the bonding stability. In a second arrangement, as shown in fig. 9, the optical unit 7 is supported and positioned by a plurality of supporting members 6 (only one is shown due to the viewing angle) arranged at intervals in the central region 31 of the flexible circuit board 3. The height of the abutting part 6 is larger than that of the light emitting part 5, and the optical unit 7 is accommodated in the inner space of the frame 2 on the premise of achieving a sufficient light mixing distance, so that the light emitting device has a better limiting effect and can achieve the purpose of thinning the backlight module. Both of the above-mentioned two arrangements can achieve the effect of positioning the optical unit 7 and prevent the optical unit 7 from directly contacting the light-emitting member 5.
Referring to fig. 10, a preferred embodiment of the display device of the present invention includes the backlight module shown in fig. 9, a sticker 8 disposed on the bendable circuit board 3, and a display panel 9, wherein the display panel 9 is fixed on the bendable circuit board 3 via the sticker 8.
In summary, the present invention directly punches or bends the bendable circuit board 3 out of the main structure of the frame 2 by punching or bending, thereby omitting the adhesive frame and the adhesive member for adhering the adhesive frame, and saving the material cost and the assembly process. In addition, the mode of bending and forming does not need to additionally design a die, and operations such as die opening and die testing are not needed, so that not only are the development timeliness and the cost saved, but also the width of the side wall area of the frame can be determined by cutting the template of the bendable circuit board 3 according to different product requirements, and therefore, the method has more product adaptability.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
