(9) An aspect of the present disclosure provides a frame component comprising, as shown in FIG. 1, a glue frame 10 and a backboard 20. The glue frame 10 comprises a glue frame sidewall 11 which encloses as a frame-type structure. The backboard 20 comprises a backboard sidewall 21 and a backboard bottom wall 22. The backboard sidewall 21 surrounds the external side of the glue frame sidewall 11. The glue frame sidewall 11 is provided with a fixing structure for connecting the glue frame 10 to the backboard 20 in a fixed manner, and the fixing structure forms a defining structure at the lower surface of the backboard bottom wall 22 for defining the position of a printed circuit board 30.

(10) The term the external side of the glue frame sidewall 11 as used herein refers to the side of the glue frame sidewall 11 which is away from the middle part of the frame-type structure, and the terms upper and lower used in the present disclosure refer to the upper part and the lower part in FIG. 1, respectively.

(11) In the present disclosure, the fixing structure can connect the glue frame 10 to the backboard 20 in a fixed manner, and the fixing structure forms a defining structure at the lower surface of the backboard bottom wall 22. The defining structure is used for defining the position of the printed circuit board 30 and plays the role of positioning the printed circuit board 30. Consequently, there is no need to arrange a fixing member individually for positioning the printed circuit board 30, thereby optimizing the structure of the frame component and simplifying the manufacturing process.

(12) As a specific implementation of the present disclosure, as shown in FIGS. 3 and 4, the fixing structure comprises a first fixing portion 13 and a second fixing portion 14 arranged at a predetermined distance from the first fixing portion 13. As shown in FIG. 5, the backboard 20 is provided with a first engagement hole 23 corresponding to the first fixing portion 13 and a second engagement hole 24 corresponding to the second fixing portion 14. The first fixing portion 13 is engaged in the first engagement hole 23 and an end of the first fixing portion 13 penetrates the first engagement hole 23 and protrudes from the lower surface of the backboard bottom wall. The second fixing portion 14 is engaged in the second engagement hole 24 and an end of the second fixing portion 14 penetrates the second engagement hole 24 and protrudes from the lower surface of the backboard bottom wall. The part of the first fixing portion 13 which protrudes from the lower surface of the backboard bottom wall and the part of the second fixing portion 14 which protrudes from the lower surface of the backboard bottom wall form said defining structure to define the printed circuit board 30 between the part of the first fixing portion 13 which protrudes from the lower surface of the backboard bottom wall and the part of the second fixing portion 14 which protrudes from the lower surface of the backboard bottom wall. The first fixing portion 13 penetrates the first engagement hole 23 and the second fixing portion 14 penetrates the second engagement hole 24 to connect the glue frame 10 to the backboard 20 in a fixed manner, while the parts of the first fixing portion 13 and the second fixing portion 14 which protrude from the backboard bottom wall 22 can clamp the printed circuit board. That is, the first fixing portion 13 and the second fixing portion 14 can further define the position of the printed circuit board 30 while connecting the glue frame 10 to the backboard 20 in a fixed manner.

(13) Specifically, the predetermined distance is the width of the printed circuit board 30. When the width of the printed circuit board 30 is relatively small, it is possible to arrange the first fixing portion 13 and the second fixing portion 14 simultaneously at the bottom surface (i.e. the surface facing the backboard bottom wall) of the glue frame sidewall 11, and enable the width of the gap between the part of the first fixing portion 13 which protrudes from the lower surface of the backboard bottom wall and the part of the second fixing portion 14 which protrudes from the lower surface of the backboard bottom wall to be consistent with the width of the printed circuit board. When the width of the printed circuit board is relatively large, it is possible to arrange the first fixing portion 13 at the external surface of the glue frame sidewall and arrange the second fixing portion 14 at the bottom surface or internal surface of the glue frame sidewall, and enable the width of the gap between the part of the first fixing portion 13 which protrudes from the lower surface of the backboard bottom wall and the part of the second fixing portion 14 which protrudes from the lower surface of the backboard bottom wall to be consistent with the width of the printed circuit board.

(14) Specifically, as shown in FIGS. 3-5, the first fixing portion 13 may comprise a plurality of first fixing pieces 13a, and the first engagement hole 23 comprises a plurality of first through holes 23a in one-to-one correspondence with the first fixing pieces 13a. The first fixing pieces 13a are engaged in the corresponding first through holes 23a, and the bottom ends of the first fixing pieces 13a protrude from the lower surface of the backboard bottom wall 22. The second fixing portion 14 comprises a plurality of second fixing pieces 14a, and the second engagement hole 24 comprises a plurality of second through holes 24a in one-to-one correspondence with the second fixing pieces 14a. The second fixing pieces 14a are engaged in the corresponding second through holes 24a, and the bottom ends of the second fixing pieces 14a protrude from the lower surface of the backboard bottom wall 22. The printed circuit board is engaged between the parts of the plurality of first fixing pieces 13a which protrude from the lower surface of the backboard bottom wall 22 and the parts of the plurality of second fixing pieces 14a which protrude from the lower surface of the backboard bottom wall 22.

(15) Certainly, the structures of the first fixing portion 13 and the second fixing portion 14 are not so limited. For example, the first fixing portion 13 may also be a plate-like structure formed by interconnecting a plurality of first fixing pieces, as long as the first fixing portion 13 and the second fixing portion 14 can connect the glue frame 10 to the backboard 20 in a fixed manner, while the ends of the first fixing portion 13 and the second fixing portion 14 protrude from the lower surface of the backboard bottom wall 22 and can clamp the printed circuit board.

(16) In an illustrative embodiment, as shown in FIGS. 3 and 4, the first fixing piece 13a is a buckle protruding from the glue frame sidewall, the first through hole is arranged at the border between the backboard sidewall 21 and the backboard bottom wall 22, and the buckle is engaged with the first through hole. Such arrangement manner enables the glue frame sidewall 11 to be attached to the backboard sidewall, and the fixing effect of the first fixing piece 13a can prevent the glue frame 10 from moving upwards relative to the backboard 20, thereby improving the stability of fixation of the glue frame 10 to the backboard 20.

(17) Further, as shown in FIG. 4, the second fixing piece 14a comprises an erect portion 141a and a bent portion 142a. The erect portion 141a is connected between the glue frame sidewall 11 and the bent portion 142a, the erect portion 141a is located within the second through hole 24a, and the upper surface of the bent portion 142a is attached to the lower surface of the backboard bottom wall 22. The glue frame 10 is made of elastic material. When the glue frame 10 is assembled with the backboard 20, the second fixing piece 14a can be pressed towards the first fixing piece 13a such that the first fixing piece 13a penetrates the first through hole 23a, while the second fixing piece 14a penetrates the second through hole 24a. When the bent portion 142a of the second fixing piece 14a protrudes from the lower surface of the backboard bottom wall 22, the elastic recovery of the second fixing piece 14a enables the upper surface of the bent portion 142a to be attached to the lower surface of the backboard bottom wall 22, thereby further improving the stability of connection between the glue frame 10 and the backboard 20.

(18) Still further, as shown in FIGS. 3 and 4, the glue frame sidewall 11 comprises an inner sidewall 111, an outer sidewall 112 and a connecting wall 113 connected between the inner sidewall 111 and the outer sidewall 112. The first fixing piece 13a is arranged on the outer sidewall 111 and the second fixing piece 14a is arranged on the inner sidewall 112 such that there is a gap between the inner sidewall 111 and the outer sidewall 112, which is advantageous to deformation of the glue frame sidewall 11 when the glue frame 10 is assembled with the backboard 20, such that the first fixing piece 13a and the second fixing piece 14a are engaged in the first through hole 23a and the second through hole 24a, respectively.

(19) Further, as shown in FIGS. 1, 3 and 4, the glue frame 10 may further comprise a support platform 12 connected to the glue frame sidewall 11 which rests on the top end of the backboard sidewall 21 to support a display panel so as to prevent scuffing resulting from direct contact between the display panel and the backboard 20.

(20) Further, as shown in FIGS. 3 and 4, a side of the support platform 12 away from the center of the frame-type structure is provided with a retaining wall 15. The region enclosed by the retaining wall 15 is used for defining the position of the display panel, thereby reducing the impact force on the display panel during the transportation of the display device.

(21) Another aspect of the present disclosure provides a display device comprising a display panel and the above frame component provided by the present disclosure. The display panel is supported on the glue frame.

(22) Specifically, as stated above, the glue frame comprises a support platform on which the display panel is arranged. The display panel is provided with a drive circuit. A side of a flexible printed circuit board (FPCB) 40 is connected to the drive circuit on the display panel, and the other side thereof is bent to the lower surface of the backboard bottom wall and connected to the printed circuit board (PCB) 30 (as shown in FIG. 2). Since there is no need to individually arrange in the frame component of the present disclosure a structure for positioning the printed circuit board, the frame component has a simple structure and consequently makes the structure of the display device simpler.

(23) It can be understood that the above embodiments are exemplary embodiments used only for illustrating the principle of the present disclosure, and that the present disclosure is not so limited. Various variations and improvements may be made by those ordinarily skilled in the art without departing from the spirit and essence of the present disclosure. These variations and improvements are regarded as falling within the scope of the present disclosure.
