DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detail below, with reference to the accompanying drawings.

Referring to FIGS. 1-3, a wrist worn electronic device 10 includes a casing 20, a display panel 30, and a touch panel 40 arranged on the display panel 30. In the embodiment, the electronic device 10 can be a watch.

The casing 20 includes an upper casing 21 and a lower casing 22. The upper casing 21 is a hollow frame including a number of sidewalls that cooperatively define a hollow space to receive the display panel 30, the touch panel 40, and other required electronic components. A protruding tab 211 is formed on the inner lateral surface of the upper casing 21. A groove 212 is formed in the protruding tab 211 and extends all around the protruding tab 211.

The lower casing 22 includes a number of sidewalls and a first protruding wall 221 and a second protruding wall 222, which both protrude from the top of the sidewalls and extend all around the edges of the sidewalls. The second protruding wall 222 is higher than the first sidewall 221. A groove 223 is formed between the first and second walls 221 and 222. The groove 223 is set to allow the upper casing 21 to fit therein.

In the embodiment, one end of the upper casing 21 is received in the groove 223 of the lower casing 22. An O-ring 60 is arranged in the groove 223 and used to prevent water from entering into the casing. In the embodiment, a waterproof screw 50 extends through the sidewall of the upper casing 21 and the second protruding wall 222 and is screwed into a support member 224 in the lower casing 22, which fixes the upper casing 21 to the lower casing 22.

The display panel 30 is received in the upper casing 21 and rests on the support member 224. The touch panel 40 is larger than the display panel 30. That is, the touch panel 40 includes a margin portion 41 that is located around the display panel 30. The margin area 41 rests on the protruding tab 211. In the embodiment, the margin portion 41 is affixed to the protruding tab 211 by waterproof adhesive. A sealing layer is thus formed between the touch panel 40 and the upper casing 21. Furthermore, the groove 212 in the protruding tab 211 can be used to accommodate waterproof adhesive to form another sealing layer between the sidewall of the upper casing 21 and the touch panel 40.

While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
