In addition, the mobile device 102 can be connected to the reading device 104 through a data transmission interface 106 . In some embodiments, the data transmission interface 106 may be a wired interface, such as a Universal Serial Bus interface. In another embodiment, the data transmission interface 106 may also be a wireless interface, such as a Bluetooth transmission interface or an infrared transmission interface.

FIG. 2 is a system block diagram of a mobile device according to a preferred embodiment of the present invention. Referring to FIG. 2 , the mobile device 102 includes a display screen 202 , a processing unit 204 , a transceiver module 206 and a storage unit 208 . The processing unit 204 can be connected to the display screen 202 , the transceiver module 206 and the storage unit 208 . In addition, the transceiver module 206 is connected to the reading device 104 through the data transmission interface 106 .

The storage unit 208 can be an electrically erasable memory, such as flash memory. In addition, the storage unit 208 can also be a hard disk. However, in some optional embodiments, the storage unit 208 can also be realized by a memory card. In the storage unit 208, an operating system 212, a driver 214, and application software 216 can be installed. In addition, the storage unit 208 can also store some digital data 218, such as electronic files such as document files, image files, and email files. In this embodiment, the storage unit 208 can also store some electronic files such as electronic books 220 .

When the mobile device 102 is running, the processing unit 204 accesses data from the storage unit 208 and displays a display frame on the display screen 202 . In particular, when the mobile device 102 is connected to the reading device 104 through the data transmission interface 106 , the reading device 104 can display the screen of the electronic document stored in the mobile device 102 .

FIG. 3 is a system block diagram of a reading device according to a preferred embodiment of the present invention. Referring to FIG. 3 , the reading device 104 provided in this embodiment includes a transceiver module 302 , a display screen 304 and an operation module 306 . The transceiver module 302 is connected to the data transmission interface 106 , and connected to the display screen 304 and the operation module 306 .

Please refer to FIG. 2 and FIG. 3 together. When the mobile device 102 is connected to the reading device 104 through the data transmission interface 106 , the mobile device 102 will transmit the image of the electronic file stored in the storage unit 208 to the transceiver module 206 . At this time, the transceiver module 206 transmits the acquired image to the reading device 104 through the data transmission interface 106 . In terms of the reading device, the image of the electronic file is received from the data interface 106 by means of the transceiver module 302 and transmitted to the display screen 304 to display the image of the electronic file.

Display screen 304 may be a bistable display, such as an electrophoretic display. The characteristic of this type of display is that it can still display the picture without power supply. Therefore, when the user uses the reading device 104 to display the image of the electronic document, the power consumption can be effectively reduced. In addition, the size of the display screen 304 is greater than that of the display screen 202 , for example, 10 inches.

When any one of the operating units 312 , 314 , 316 and 318 is enabled, the operating module 306 will generate a corresponding operating signal S1 to the transceiver module 302 . At this time, the transceiver module 302 transmits the operation signal S1 to the mobile device 102 through the data transmission interface 106 .

When the operation signal S1 is sent to the mobile device 102 through the data transmission interface 106 , the transceiver module 206 receives it and sends the operation signal S1 to the processing unit 204 . At this point, the processing unit 204 can perform corresponding calculation processing according to the operation signal S1. In this way, using the computing capability of the processing unit 204 in the mobile device 102 to process the operation signal S1 of the reading device 104 can reduce or replace the cost of disposing the processing unit in the reading device 102 and save the power consumption of the reading device 102 .

For example, when the user reads an e-book on the reading device 104 and presses the operation unit representing "next page", the reading device 104 will generate a corresponding operation signal S1. The processing unit 204 of the mobile device 102 sends the display screen of the next page of the e-book that the user is reading to the reading device 104 to complete the "next page" operation in response to the operation signal S1. Another example is the “send email” operation signal of the reading device 104 , which uses the email function on the mobile device 102 to send out the email written by the user with the help of the reading device 104 .

From the above, when the reading device 104 is connected to the mobile device 102 through the data transmission interface 106 , the processing unit 204 of the mobile device 102 processes and responds to the operation signal of the reading device 104 . Therefore, the reading device 104 does not need to have the function of calculation, so the cost of hardware can be reduced. However, in the embodiment of FIG. 3 , when the reading device 104 is disconnected from the mobile device 102 or when the mobile device is out of power, the reading device cannot continue to display the screen of the electronic document.

When the reading device 104 is not connected to the mobile device 102 , the processing unit 402 can be responsible for the operation of the reading device 104 . For example, when one of the operating units is enabled, the operating unit will output a corresponding operating signal S1 to the processing unit 402 for processing.

However, in this embodiment, when the reading device 104 is connected to the mobile device 102 through the data transmission interface 106 , the processing unit 402 will be set to an idle state. Therefore, all the information to be processed transmitted to the processing unit 402, such as the operation signal S1, etc., will be directly transmitted to the transceiver module 302, and then transmitted to the mobile device 102 through the data transmission interface 106, and the mobile device 102 is responsible for responding to these information, The detailed narration is disclosed above, so no more details are given here.

In addition, the reading device 104 obtains a copy of the electronic file stored in the mobile device 102 through the data transmission interface 106 . The copy is received by the transceiver module 302 and then stored in the storage unit 404 . Likewise, the storage unit 404 can be implemented by a flash memory, a hard disk or a memory card. In this embodiment, when the reading device 104 is disconnected from the mobile device 102, or when the mobile device 102 is out of power, the user can still read the electronic files stored in the storage unit 404 by operating the reading device 104 screen.

FIG. 5 is a flowchart of steps of a control method of a reading device according to a preferred embodiment of the present invention. Please refer to FIG. 5 , the control method provided by this embodiment can be implemented in the form of software, and can be written into the processing unit 402 or the transceiver module 302 in the reading device 104 as described above.

When one of the operation units is enabled (that is, "Yes" marked in step S508), as described in step S510, a corresponding operation signal is generated to the mobile device, so that the mobile device performs corresponding operations according to the operation signal. Operation processing.

FIG. 6 is a flowchart of steps of a control method of a mobile device according to a preferred embodiment of the present invention. Please refer to FIG. 6 , the control method provided by this embodiment can be implemented in the form of application software 216 in FIG. 2 . In some other embodiments, the control method provided by this embodiment may be written in the processing unit 204 in FIG. 2 in the form of software.
