2. Description of the Prior Art
Recently, a portable electronic device, such as a mobile phone, a personal digital assistant and so on, has been widely utilized in human's daily life. With development of touch control technology, a touch panel module has been implemented in the portable electronic device and become a trend in the field. Generally speaking, a conventional touch panel module includes a transmission cable disposed through a casing of the portable electronic device for coupling a circuit board of the portable electronic device, such that signals are transmitted between the touch panel module and the circuit board of the portable electronic device.
However, liquids, such as water, coffee and so on, can easily enter the interior of the portable electronic device no matter via a position which the transmission cable passes through the casing of the portable electronic device or via a gap between the touch panel module and the casing of the portable electronic device. It results in damage of internal components of the portable electronic device and causes the product to function abnormally. Thus, how to design a waterproof touch panel module and a portable electronic device therewith becomes an issue in the industry.
The present invention provides a waterproof touch panel module and an electronic device therewith for solving above drawbacks.
According to an embodiment of the present invention, a touch panel module includes a frame, a base plate, a touch material layer, a transmission cable and a first attaching layer. The frame is disposed on a casing, and an opening and a breach connected to the opening are formed within the frame. The base plate is disposed on the casing and located inside the opening. The touch material layer is disposed on the base plate, and a peripheral portion of the touch material layer is attached to the frame for sealing the base plate inside the opening. The transmission cable is connected to the touch material layer in a position near the peripheral portion and passes through the casing via the breach. The first attaching layer attaches the frame and the casing for sealing a gap between the frame and the casing, so as to prevent liquids from entering the opening and the breach via the gap between the frame and the casing.
According to another embodiment of the present invention, an electronic device includes a casing and a touch panel module. The touch panel module includes a frame, a base plate, a touch material layer, a transmission cable and a first attaching layer. The frame is disposed on the casing, and an opening and a breach connected to the opening are formed within the frame. The base plate is disposed on the casing and located inside the opening. The touch material layer is disposed on the base plate, and a peripheral portion of the touch material layer is attached to the frame for sealing the base plate inside the opening. The transmission cable is connected to the touch material layer in a position near the peripheral portion and passes through the casing via the breach. The first attaching layer attaches the frame and the casing for sealing a gap between the frame and the casing, so as to prevent liquids from entering the opening and the breach via the gap between the frame and the casing.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
In the following detailed description of the embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced.

In addition, the electronic device 30 further includes a touch panel module 34 disposed on the casing 32. The touch panel module 34 provides a user with an operating interface, such that the user can perform touch control operation, such as a page turning, a zooming in and so on, accordingly. Furthermore, the touch panel module 34 includes a frame 36 and a base plate 38. The frame 36 is disposed on the casing 32, and an opening 361 and a breach 363 connected to the opening 361 are formed within the frame 36. The base plate 38 is disposed on the casing 32 and located inside the opening 361 on the frame 36, as shown in
As shown in
In addition, a peripheral portion 401 of the touch material layer 40 of the touch panel module 34 is attached to the frame 36, so as to seal the base plate 38 of the touch panel module 34 inside the opening 361 within the frame 36. In this embodiment, a size of the touch material layer 40 is substantially identical to a size of the frame 36 and a size of the casing 32 of the electronic device 30. Accordingly, a periphery of the touch material layer 40 can be aligned with a periphery of the frame 36 and a periphery of the casing 32, as shown in
As mentioned above, when the touch panel module 34 of the electronic device 30 is adopted the design with whole planar coverage for covering the whole top surface of the casing 32, the frame 36 can be made of transparent plastic materials for preventing the user from seeing structural body of the frame 36 via the touch panel module 34 with the aforesaid design with whole planar coverage as the electronic device 30 is in use. Accordingly, it can further enhance the appearance integrity and aesthetic feeling of the electronic device 30. The design that the frame 36 is made of transparent materials can be omitted, and it depends on practical demands.
As shown in
Since the base plate 38 is made of glass materials and since the glass materials are practically brittle, if a breach is formed on the periphery of the base plate 38 made of glass materials, it will cause the base plate 38 made of glass materials to crack easily due to brittleness and thus reduce a yield rate of the electronic device 30. In the present invention, the breach 363, which allows the transmission cable 42 to pass through the casing 32 and couple with the circuit board of the electronic device 30, is disposed on the frame 36 instead of on the base plate 38 of the touch panel module 34, so as to prevent the aforesaid crack issue resulting from the breach disposed on the base plate 38 made of glass materials, and thus it enhances the yield rate of the electronic device 30.
Furthermore, a containing space 44 is formed between the frame 36 and the base plate 38, and the containing space 44 is used for containing the transmission cable 42, as shown in
As shown in
In addition, the touch panel module 34 further includes a second attaching layer 48 for attaching the frame 36 and the peripheral portion 401 of the touch material layer 40 for sealing a gap between the frame 36 and the peripheral portion 401 of the touch material layer 40, so as to prevent liquids from entering the opening 361 and the breach 363 within the frame 36 via the gap between the frame 36 and the peripheral portion 401 of the touch material layer 40. In other words, the second attaching layer 48 is capable of preventing the liquids from entering the opening 361 and the breach 363 within the frame 36 via the gap between the frame 36 and the peripheral portion 401 of the touch material layer 40, so as to further avoid the liquids from entering interior of the electronic device 30, resulting in damage of the internal components, via a position the transmission cable 42 passing through the frame 36.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
