Description

Thin electronic device

The present invention relates to a consumer electronic device.

Consumer electronic devices, especially consumer electronic devices placed on the table or wall-mounted, such as electronic photo frames, LCD TVs, etc., are becoming thinner and thinner. Thin electronic devices are not only easy to use in more compact environments, but are also more attractive in appearance. Therefore, it has been a development direction of the technology in the field to make consumer electronic devices thinner through various technical measures.

In view of the above, an electronic device is provided which has a thin profile.

The thin electronic device includes a housing in which a display unit and a printed circuit board are mounted, the printed circuit board surrounding a periphery of the display unit.

Since the PCB board is mounted around the display unit, the electronic device has an extremely thin thickness compared to an electronic device in which a conventional PCB board is mounted under the display unit.

Referring to Figure 1, an electronic device 10 in accordance with a preferred embodiment of the present invention is disclosed. In the embodiment, the electronic device 10 is an electronic photo frame. The electronic photo frame 10 includes a housing composed of a front cover 11 and a rear cover 21, and a display unit 13 and a printed circuit board (PCB board) 19 are mounted in the housing. The PCB board 19 surrounds the periphery of the display unit 13. In the present embodiment, the PCB board 19 has a mouth shape, and an opening 20 is formed on the opening 20 The size is larger than the size of the display unit 13. In other embodiments, the PCB board 19 can also be L-shaped or U-shaped.

In the present embodiment, the rear cover 21 has a specific structure in which the rear cover 21 includes a bottom surface 22 and an outer side wall 24 extending upward from the outer edge of the bottom surface 22 and enclosed. An opening 23 is formed in the bottom surface 22. The rear cover 21 also includes an inner side wall 27 extending upwardly from the opening 23 of the bottom surface 22, the inner side wall 27 being much smaller in height than the outer side wall 24. A plurality of limiting blocks 25 are formed from the side of the inner side wall 27 adjacent to the outer side wall 24, and the limiting block 25 is higher than the top of the inner side wall 27.

The front cover 11 has an opening 12 for exposing the display unit 13. In the present embodiment, the front cover 11 is opaque.

The display unit 13 includes a transparent plate 14, a display screen 15, a display cover 17, and a transparent frame 18. The size of the transparent plate 14 and the transparent frame 18 is slightly larger than the size of the openings 12, 23 on the front cover 11 and the rear cover 21, and the size of the display screen 15 and the display screen cover 17 is smaller than the size of the openings 12, 23. Display 15 includes a transparent connection 16 for electrical connection to PCB board 19. The display screen 15 is mounted in the display screen cover 17, and the transparent panel 14 limits the display screen 15 to the display screen cover 17, and the transparent frame 18 is fitted over the display screen cover 17. The display screen 15, the display screen cover 17, and the transparent frame 18 are assembled together by a suitable means such as gluing.

When the electronic photo frame 10 is mounted, first, the PCB board 19 is mounted between the inner and outer side walls 24, 27, at which time the electronic components on the PCB board 19 and the PCB board 19 are raised above the inner side wall 27. Then, the display unit 13 is passed through the opening 20 on the PCB board 19 and placed on the inner side wall 27. The limiting block 25 defines the display unit 13 to connect the transparent connecting line 16 with the corresponding interface on the PCB board 19. most Thereafter, the front and rear covers 11, 21 are assembled by an appropriate means such as a screw connection, thereby completing the assembly of the electronic photo frame 10.

The PCB board 19 and the display unit 13 can also be mounted in a housing composed of the front cover 11 and the rear cover 21 by other means such as screw connection.

Please refer to FIG. 2 and FIG. 3 , which are respectively a front view and a front view appearance view of the electronic photo frame 10 . Due to the relationship of the openings 12, 23 and the transparent plate 14 and the transparent frame 18, a visually transparent region 30 is formed between the front cover 11 and the display screen 15 and the display screen cover 17, thereby causing the display screen 15 to float in the air.
