The image module 130 includes a camera module for taking photos or performing image processing such as video recording.

In addition, a magnet is disposed inside the protective cover 200, and the touch electronic device 100 is configured with a Hall sensor. A Hall sensor is a magnetic sensor that senses changes in an external magnetic field (such as a magnet inside a protective envelope) and converts it into a difference in output voltage. The touch electronic device 100 can sense whether the protective cover 200 covers the touch electronic device 100 by the configuration of the magnet and the Hall sensor. When the protective cover 200 covers the touch electronic device 100, the user can view the content displayed by the touch panel 120 and touch the transparent area 260. Control operation. Therefore, the user can operate the touch electronic device 100 without opening the protective cover 200.

In an embodiment, the transparent region 260 of the protective envelope 200 is elongated in shape. For example, the size of the touch panel 120 is about 4 吋 to 7 吋, and the position of the transparent area 260 is equivalent to the central position of the touch panel 120. The transparent region 260 has a length of about 4 cm to 10 cm and a width of about 1 cm to 2 cm. In other words, the width of the transparent region 260 is equivalent to the width of the thumb of the thumb of a general user. The length of the transparent area 260 is equivalent to the maximum distance that the thumb can slide on the touch panel 120 when the user holds the touch electronic device 100. The transparent region 260 may be made of a transparent material such as a plastic sheet or a glass sheet. The transparent region 260 can also be a hollowed out region of the protective envelope 260. When the protective cover 200 covers the touch electronic device 100, only the portion corresponding to the transparent region 260 displays the screen for the touch panel 120, and the other portions are not lit to save power. Therefore, the shape and size of the transparent region 260 can enable the user to conveniently and effectively touch the touch electronic device 100 even if the single-hand operation is performed while the protective cover 260 covers the touch electronic device 100. operating.

Display state.

In another embodiment, when the touch electronic device 200 starts the code second meter At the time of the function, the transmissive area 260 will display an interface related to the code second timing function. When the user long presses the transparent area 260 (ie, performs the touch operation T3), the transparent area 260 displays a plurality of time symbols to enable the user to quickly select the time to count down, for example, 30 seconds, 1 minute, or 3 minutes. Wait. When the user clicks on any of the time symbols (ie, performs the touch operation T2), the touch electronic device 200 starts counting down according to the time of the click. It should be noted that when the user touches other areas of the transparent area 260 other than the plurality of time symbols, the plurality of time symbols disappear and return to the display state of the original transparent area 260.

It should be noted that when the transparent area 260 senses another touch operation (fourth touch operation) different from the touch operations T1 to T3, the touch electronic device 200 performs a preset function. The preset function may be preset by the touch electronic device 200 or a commonly used function determined by the user. For example, the preset function may include a camera function, a recording function, or a flashlight function. When the user needs to perform any of the above functions, if the fourth touch operation is performed on the transparent area 260, for example, two consecutive clicks, the function can be quickly activated without switching by one touch operation. The fourth touch operation described above is only used for illustrative purposes, and the present invention is not limited thereto.

The user can click on any of the three notification symbols (ie, perform touch operation T2) to view or reply. When the user When the notification symbol of the missed call is clicked, the transparent area 260 displays the screen as shown in Fig. 8B. At this time, the first side and the second side of the transparent area 260 respectively display the symbols dialed and returned to the upper layer, and the middle part of the transparent area displays the contact name of the missed call. When the user clicks back to the symbol of the previous layer, the transparent area 260 returns to the screen shown in Fig. 8A. When the user clicks on the dialing symbol, the touch electronic device 200 dials the contact person of the missed call.

In addition, when the user presses (ie, performs touch operation T3) the middle portion of the transparent area 260, the part dynamically displays the contact details. As shown in FIG. 8C, the middle portion of the transparent area 260 dynamically displays other details such as the contact's telephone number, dialing time, and the like. At this time, when the user clicks back to the symbol of the previous layer, the transparent area 260 returns to the screen shown in FIG. 8A. When the user clicks on the dialing symbol, the touch electronic device 200 dials the contact person of the missed call. Further, in the embodiment shown in FIG. 8D, the user can perform a sliding operation along the long axis direction of the transparent area 260 to display the next or previous missed call message.
