FIGS. 1-3 illustrate an embodiment of the display apparatus 100. The display apparatus 100 includes a display module 10, a circuit mechanism 20 mounted on a back surface of the display module 10, and a location mechanism 30 above the circuit mechanism 20. The circuit mechanism 20 provides signals to the display module 10 for controlling the display module 10 to display images. The location mechanism 30 locates the display apparatus 100 on an external structure, such as a wall. In at least embodiment, the display apparatus 100 is a television. A size of the circuit mechanism 20 is smaller than a size of the display module 10.
The display module 10 includes a frame 110, a display panel 120 received in the frame 110, and two positioning portions 130. The frame 110 is substantially rectangular. The display panel 120 for displaying images is exposed from the frame 110. The positioning portions 130 are symmetrically located on a surface of the frame 110 away from the display panel 120. The positioning portion 130 cooperates with the circuit mechanism 20 to locate a position of the circuit mechanism 20 on the frame 110. The positioning portion 130 defines a first opening 131 and a plurality of receiving portions 132. The first opening 131 is adjacent to a side of the frame 110. In at least one embodiment, the display module 10 includes two positioning portions 130 and four receiving portions 132. The positioning portions 130 are symmetrically located around a vertical line through the center of the display panel 120. The receiving portions 132 are respectively located on corners of a rectangular. The first opening 131 is set in a center of the rectangular where the receiving portions 132 are contained in.
The circuit mechanism 20 includes a circuit module 21 and two fixing portions 22 corresponding to the positioning portions 130. The circuit module 21 provides electrical signals to the display panel 120, and is rotatably inserted into the fixing portions 22. The fixing portion 22 fixes the circuit module 21 on the frame 110. In at least one embodiment, the circuit module 21 is electrically connected to the display panel 120.
The circuit module 21 includes a housing 210, a main board 220, a power board 230, and two loudspeakers 240. The housing 210 includes a first cover 211 and a second cover 212. The first cover 211 cooperates with the second cover 212 to form a receiving space for receiving the main board 220, the power board 230, the loudspeakers 240, and other electrical components (not shown). The main board 220, the power board 230, and the loudspeakers 240 are mounted on the first cover 211. In at least one embodiment, the main board 220 and the power board 230 are arranged in a line. In other embodiments, the main board 220 and the power board 230 are overlapped.
The first cover 211 includes two shafts 213 mounted on opposite side surfaces of the first cover 211. An axis of the shaft 213 is perpendicular to the side surface of the first cover 211. The shaft 213 is a cylinder which is substantially hollow. The shaft 213 defines a gap 214 facing the frame 110.
The main board 220 is a printed circuit board providing driving signals and sequential control signals to the display panel 120.
The power board 230 is a printed circuit board for providing voltages. The power board 230 is electrically connected to the main board 220.
The loudspeakers 240 are arranged on opposite corners of the first cover 211.
The display apparatus 100 locates the circuit mechanism 20 for driving the display module 10 outside of the display module 10, thus a thickness of the display module 10 is decreased.
FIG. 4 illustrates the embodiment of the fixing portion 22. The fixing portion 22 cooperates with the positioning portion 130 to fix the circuit mechanism 21 on the frame 110. The fixing portion 22 includes a main body 221. The main body 221 is substantially arched. The main body 221 defines a plurality of through holes 222 corresponding to the receiving portions 132, and a pivot hole 223 and an second opening 224 are also defined. The pivot hole 223 receives the shaft 213. The second opening 224 corresponds to the first opening 131, and communicates with the pivot hole 223. In at least embodiment, the through holes 222 are arranged on corners of the main body 221. The second opening 224 is set in a center of the rectangular where the through holes 223 are contained in.
The circuit mechanism 20 further includes a flexible flat cable (FFC) 260. An end of the FFC 260 is electrically connected to the main board 220. An opposite end of the FFC 260 is electrically connect to the display panel 120.
In assembly, the main board 220, the power board 230, and the loudspeaker 240 are mounted on the first cover 211. The first cover 211 and the second cover 212 cooperate with each other to form a receiving space. The shafts 213 are received in the pivot holes 223. The gap 214 faces the second opening 224. The second opening 224 faces the first opening 131. The FFC 260 passes through the shaft 213, the gap 214, and the second opening 224, and the first opening 131 in that orderly to be electrically connected to the display panel 120. The through hole 222 corresponds to the receiving portion 132 to fix the fixing portion 21 on the frame 110 via screws (not shown).
In other embodiments, the display module 10 communicates with the circuit mechanism 20 wirelessly. Thus, the power board 230, the fixing portion 22, and the FFC 260 can be omitted.
In use, the display apparatus 100 integrates the main board 220, the power board 230, and the loudspeaker 240 into the circuit mechanism 20. The circuit mechanism 20 for driving the display module 10 is located outside of the display module 10 and is hung on the back surface of the frame 110. Therefore, a thickness of the display module 10 is decreased.
While various exemplary and preferred embodiments have been described, the disclosure is not limited thereto. On the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
