Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 2, a mobile terminal includes a first display screen 1, a processor 2 and a display module 3.
The display module 3 comprises a thermoelectric generator 31, a second display screen 32 and a signal transmission module 33;
the thermoelectric generator 31 is electrically connected with the second display screen 32 through a direct current transformer 34;
the direct current transformer 34 is used for converting the alternating current generated by the thermoelectric generator 31 into direct current;
a first end of the signal transmission module 33 is electrically connected with the second display screen 32, a second end of the signal transmission module 33 is electrically connected with the processor 2 of the mobile terminal, and the signal transmission module 33 is used for receiving the target information sent by the processor 2 and outputting the target information to the second display screen 32;
the second display screen 32 is used to display target information.
Here, the first display screen 1 is a touch display screen currently set on the mobile terminal, and it can be understood that the first display screen 1 is a main screen on the mobile terminal; the second display screen 32 is another display screen different from the first display screen 1, and it can be understood that the second display screen 32 is an auxiliary screen on the mobile terminal. Generally, the second display screen 32 does not occupy the area of the first display screen 1, the second display screen 32 may be disposed on the back side of the mobile terminal, or may be disposed on the front side of the mobile terminal, and the size of the second display screen 32 is far smaller than that of the first display screen 1.
In the embodiment of the present invention, the thermoelectric generator 31 is configured in the mobile terminal, and the second display screen 32 provides power independently.
The thermoelectric generator 31 is a device that generates electricity by using a thermoelectric effect, and when the temperature of the second display screen 32 is lower than the external environment temperature, the thermoelectric generator 31 may generate an alternating current, and the alternating current may be converted into a direct current by the direct current transformer 34 for the second display screen 32 to use.
For example, the thermoelectric generator 31 can generate power by using the temperature difference between the body temperature of the human body and the second display screen 32, so that the opportunity that the human body contacts the second display screen 32 can be fully utilized to generate power, and the thermoelectric generator has the beneficial effect of convenience in use.
In the embodiment of the invention, the thermoelectric generator is arranged to supply power to the second display screen, and the thermoelectric generator can generate power by utilizing the temperature difference between the second display screen and the external environment, so that the embodiment of the invention can reduce the power consumption of the battery module of the mobile terminal.
In addition, in order to ensure that the second display screen 32 is continuously supplied with electric energy when the thermoelectric generator 31 cannot work or when the electric quantity of the thermoelectric generator 31 is insufficient, the battery module 4 of the mobile terminal can be used as a standby power supply of the second display screen 32.
Specifically, as shown in fig. 3, the battery module 4 is electrically connected to the second display screen 32 through the discharging module 5 and the switching module 6. In this way, the battery module 4 is boosted by the discharging module 5 to become a 5V/9V dc power supply commonly used by the user, and supplies power to the second display screen 32 through the switching module 6.
The second display screen 32 of the embodiment of the present invention is used for continuously displaying the target information for the user to directly view. Because the second display screen 32 can be used only for displaying the target information, and the size of the second display screen 32 can be made very small, the power consumption of the second display screen 32 can be much smaller than that of the first display screen 1, so that the thermoelectric generator 31 can continuously supply power to the second display screen 32, and the second display screen 32 can continuously display the target information.
In actual use, the user wakes up or lights up the first display 1 of the mobile terminal more frequently, which is generally based on the following two requirements: firstly, a user needs to wake up the first display screen 1 to check time or date; secondly, users, especially users who rely on the mobile terminal, need to check whether there is a missed incoming call, short message or instant communication message from time to time, and with the increase of various application programs in the mobile terminal, most of the information may be irrelevant push messages. Thus, the operation of frequently waking up the first display screen 1 not only wastes the time of the user, but also causes the power consumption of the mobile terminal to be excessively consumed due to the excessively frequent waking up or lighting of the first display screen 1.
Based on the user requirement, the target information may be time information and/or date information, or may be missed call prompt information, unread short message prompt information, or unread instant communication message prompt information, and the like.
The operation principle of the embodiment of the present invention is described in detail below by taking the missed call as an example.
If the user does not respond to the incoming call received by the mobile terminal in time, the processor 2 of the mobile terminal sends a missed call prompt message to the signal transmission module 33, where the missed call prompt message may include the number of the incoming call, the time of the incoming call, and the like. When receiving the incoming call prompt message, the signal transmission module 33 outputs the missed call prompt message to the second display screen 32, and the second display screen 32 displays the missed call message.
When the user checks the missed call information through the second display screen 32, if the missed call information needs to be processed, for example, a call needs to be called back, the missed call information can be processed after the first display screen 1 is awakened; if the missed call information does not need to be processed, the awakening of the first display screen 1 can be reduced.
After the missed call information displayed on the second display screen 32 is processed, the missed call information is no longer displayed on the second display screen 32, and at this time, time or date information can be displayed on the second display screen 32, so that the user can conveniently view the time or date.
If the amount or content of the target information displayed on the second display screen 32 is excessive, a scroll display may be performed on the second display screen 32 for the user to view.
The second display 32 in the embodiment of the present invention may be a currently-used L ED display or a liquid crystal display, etc.
The mobile terminal of the embodiment of the invention can comprise: any one of a mobile phone, a tablet computer, a notebook computer, a palm computer, a navigation device, a wearable device, an electronic book reader, a laptop portable computer, a vehicle-mounted computer, a desktop computer, and an intelligent television.
Optionally, the display module 3 is integrally arranged with a Home key or a fingerprint module of the mobile terminal. Fig. 1 shows a case where the display module 3 is integrally provided with a Home key of the mobile terminal.
In the embodiment, the display module 3 and the Home key or the fingerprint module of the mobile terminal can be integrally arranged, so that the Home key or the fingerprint module of the mobile terminal can synchronously realize the function of continuously displaying the target information on the premise of meeting the appearance requirement of the mobile terminal; and the habit of obtaining information by the user is also met.
The display module 3 of the embodiment of the invention is not necessarily combined with the conventional key on the mobile terminal, and can also be arranged at other parts of the mobile terminal.
Optionally, as shown in fig. 4, the thermoelectric generator 31 is a thermoelectric generation sheet 311, and the second display screen 32 is attached to the thermoelectric generation sheet 311.
In the embodiment of the present invention, whether the thermoelectric generator 31 generates electricity or not depends on the temperature difference between the temperature of the second display screen 32 and the external environment, and the thermoelectric generator 31 is configured in a sheet shape, so that the contact area between the thermoelectric generator 31 and the second display screen 32 can be increased, the thermoelectric generator 311 can more directly sense the temperature of the second display screen 32, and the power generation efficiency of the thermoelectric generator 311 can be increased.
Optionally, as shown in fig. 4, the second end of the signal transmission module 33 is electrically connected to the processor 2 of the mobile terminal through an FPC (Flexible Print Circuit) 7.
Optionally, the second display screen 32 is an electronic ink screen.
The electronic ink screen is also called as an ink screen, and the ink screen displays close to paper, has the characteristic of no reflection of light and has a certain protection effect on eyes. Further, since the content is displayed by the ink screen which needs to be lit unlike the first display screen 1, the second display screen 32 can continue to display without being lit, and power consumption is low.
Alternatively, as shown in fig. 5, when the power generated by the thermoelectric generator 31 is surplus, the power of the thermoelectric generator 31 may be stored in the battery module 4 of the mobile terminal. Specifically, the thermoelectric generator 31 is electrically connected to the battery module 4 through the dc transformer 34, and the ac power generated by the thermoelectric generator 31 is converted into dc power through the dc transformer 34 and charged into the battery module 4.
Optionally, when the signal transmission module 33 outputs the target information to the second display screen 32, the second display screen 32 is lighted.
In order to play a role of reminding the user, the second display screen 32 may be lighted when the signal transmission module 33 outputs the target information to the second display screen 32. The time of lighting may be set, for example, lighting for one second, three seconds, or five seconds, and so on.
Optionally, as shown in fig. 6, the display module 3 further includes a touch module 35, a first end of the touch module 35 is electrically connected to the second display screen 32, a second end of the touch module 35 is used for being electrically connected to the processor 2, and the touch module 35 is used for sending a touch signal received by the second display screen 32 to the processor 2.
In this embodiment, the display module 3 may further include a touch module 35, for example, when the number or content of the target information displayed on the second display screen 32 is large, the user cannot directly view all the target information on the second display screen 32, and therefore, the target information displayed on the second display screen 32 can be flipped over through the touch module 35, so as to improve the convenience of information viewing.
Optionally, as shown in fig. 7 or fig. 8, the display module 3 further includes a first temperature detection module 36 and a second temperature detection module 37, the first temperature detection module 36 is configured to detect the temperature of the second display screen 32, the second temperature detection module 37 is configured to detect the ambient temperature, and both the first temperature detection module 36 and the second temperature detection module 37 are electrically connected to the thermoelectric generator 31.
It should be noted that, the embodiment of the present invention can independently protect one display module, and has the same beneficial effects, and further description is omitted to avoid repetition.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention.
