Moreover, the plurality of batteries are connected in series or in parallel, so that the overall parameters of the first battery 102 can be more conveniently adjusted to be the same as the capacity of the main battery of the terminal device, or meet other required conditions.
It should be noted that, in the above embodiments, when the display screen is a flexible display screen, the display screen includes, but is not limited to, any component having a display function, such as a liquid crystal display screen, a quantum dot display screen, and electronic paper.
The screen module provided by the embodiment comprises a display screen and a first battery, wherein the thickness of the first battery is smaller than or equal to that of the display screen, the thinned first battery is attached and fixed on the display screen, supplies power to the display screen, and forms an integrated structure with the display screen, so that an independent display function is realized, and the experience effect of a user is improved; and because first battery thickness is thin, occupation space is little, can the large tracts of land laminating display screen, the big bigger the display screen then the area that first battery can laminate is big more, therefore battery capacity and electric quantity also promote correspondingly by a wide margin, the duration is stronger, can satisfy the use of large screen.
This embodiment still provides a display module assembly, and this display module assembly includes a plurality of as above embodiment the screen module, a plurality of screen module concatenations.
For example, please refer to fig. 8 and 9, fig. 8 is a display module formed by splicing 3 screen modules, which are A, B, C respectively; fig. 9 is a display module assembled by 6 screen modules, which is A, B, C, E, F, G respectively), so that the display module can change the display area by assembling or disassembling the screen modules.
Wherein, a plurality of screen modules can splice and obtain arc display screen, square display screen, or other shapes that set up according to the actual demand. It should be noted that, adjacent screen modules can be fixed by a fixing device, a seamless splicing mode is adopted to obtain a complete large screen, and splicing lines cannot appear to influence the display effect. When a certain screen module breaks down in the display module, the screen module can be directly and independently detached for maintenance, so that the maintenance cost is reduced, and the maintenance efficiency is improved.
According to the display module provided by the embodiment, the screen module can realize an independent display function, so that the display module can be independently disassembled to independently display according to the requirements of users, and the display module is convenient for users to carry or hold; or a plurality of screen modules are spliced, so that the display area is increased, and the abundant display effect is realized.
The embodiment also provides a terminal device, which includes the screen module or the display module as described in the above embodiments, and since the screen module can implement an individual display function, the terminal device can independently disassemble the screen module to display separately according to the user's requirement, or combine the screen module with other module units inside to obtain a multifunctional combination. Meanwhile, the internal space of the traditional terminal equipment is limited, the screen module is not provided with a battery for independently supplying power to the display screen, the power supply quantity is limited, the first battery is very thin and is attached to the display screen, the occupation of the internal space of the terminal equipment is hardly increased when the screen module is applied to the terminal equipment, and the first battery can provide extra power for the terminal equipment in the limited internal space so as to be used by a large screen; and, first battery can laminate the display screen by a large scale, therefore terminal equipment's extra battery capacity and electric quantity also promote correspondingly by a wide margin, can promote terminal equipment's use duration greatly.
Further, the terminal device further includes a second battery.
In one embodiment, the first battery and the second battery are independent, and the first battery supplies power to the display screen of the screen module; the second battery is a main battery of the terminal device and supplies power for other modules except the screen module in the terminal device. Therefore, the first battery and the second battery respectively supply power to the corresponding modules, and the independence of power supply control is realized.
In another embodiment, on the basis that the first battery supplies power to the display screen of the screen module, the first battery and the second battery can be connected in series or in parallel to supply power to other modules of the terminal device. Because the electric quantity of screen module promotes by a wide margin, therefore first battery probably has more residual capacity when supplying power for the display screen, perhaps has a large amount of idle electric quantities when the display screen need not show in first battery, therefore unite the residual capacity of first battery or idle electric quantity and the electric quantity of second battery, can improve the power supply electric quantity of other modules, further improve terminal equipment's use duration, improve the availability factor of electric quantity simultaneously.
When the first battery is connected with the second battery in series, the battery parameters of the first battery are the same as those of the second battery; battery parameters include electrode material and battery capacity. For example, when the first battery is a flexible battery, the flexible battery is a pouch battery, and if the system used by the second battery is a 4.45V lithium cobaltate/graphite system, the system of the first battery is also a 4.45V lithium cobaltate/graphite system.
The first battery and the second battery can be charged by selecting a direct charging mode or a charger power supply mode according to the connection mode and the actual voltage condition. For example, when the first battery and the second battery are not connected or are connected in parallel, the first battery or the second battery may be directly charged by the charger; when the first battery and the second battery are connected in series, the charging mode can be selected according to the voltage condition of the adapter.
Alternatively, when the first battery is connected in series with the second battery (constituting the battery pack 20), referring to fig. 10, the terminal device further includes a switching unit 30, a charge adjusting unit 40, and a control unit 50. The first battery and the second battery are connected in series, so that higher voltage can be provided besides larger capacity, and more functional application is possible.
And a switching unit 30 connected between the adapter 60 and the battery pack 20 for connecting or disconnecting a direct charging path of the battery pack 20.
And a charge adjusting unit 40 connected between the adapter 60 and the battery pack 20 for adjusting an output voltage of the adapter 60 to charge the battery pack 20.
A control unit 50 respectively connected to the adapter 60, the switch unit 30 and the charging adjustment unit 40, for closing the charging adjustment unit 40 and controlling the switch unit 30 to communicate with the direct charging path of the battery pack 20 when the output voltage of the adapter 60 is within the direct charging threshold range, so that the adapter 60 charges the battery pack 20; when the output voltage of the adapter 60 exceeds the direct charging threshold range, the charging adjustment unit 40 is activated and the switching unit 30 is controlled to cut off the direct charging path of the battery pack 20, so that the adapter 60 outputs the voltage to the charging adjustment unit 40.
Wherein the terminal device is connected to an external adapter 60 when the battery pack 20 needs to be charged. The adapter 60 is connected to an external power source, and converts a voltage output from the external power source to output a voltage to the battery pack 20 to supply power. Different adapters 60 have different output voltages correspondingly, and when the output voltage is in the direct charging threshold range, the adapters 60 can directly charge the battery pack 20; when the output voltage of the adapter 60 is outside of the direct charging threshold range, for example, less than the direct charging threshold, the output voltage of the adapter 60 needs to be adjusted to charge the battery pack 20. The direct charging threshold range refers to a voltage range between a first threshold and a second threshold, and the range exceeding the direct charging threshold range refers to the output voltage being smaller than the first threshold or larger than the second threshold. The direct charging threshold range may be set according to the voltage condition of the battery pack 20. For example, if the direct charging threshold range is set to be 10V or more, the battery pack 20 can be directly charged through the direct charging path when the output voltage of the adapter 60 can output 10V; when the output voltage of the adapter 60 is low, for example, 5V, the direct charging of the battery pack 20 cannot be supported. When the terminal device includes two batteries connected in series, a dedicated charger (for example, 10V can be output) that can charge the two batteries connected in series at the same time may be provided. If only a common charger (for example, only 5V can be output), the voltage can be increased by the charging adjustment unit 40, so that two batteries connected in series can be charged.
The switching unit 30 is a unit having a switching function, and is controlled by the control unit 50, and when the output voltage of the adapter 60 is within the direct charging threshold range, the switching unit 30 communicates with the direct charging path of the battery pack 20, so that the adapter 60 charges the battery pack 20; when the output voltage of the adapter 60 exceeds the direct charging threshold range, the switching unit 30 cuts off the direct charging path of the battery pack 20. The specific device of the switching unit 30 is not limited as long as the switching function can be achieved. For example, the switch unit 30 may include a switch controlled by the control unit 50, and when the output voltage of the adapter 60 is within the direct charging threshold range, the control unit 50 controls the switch to be turned on to communicate with the direct charging path of the battery pack 20. The direct charging path is a path through which the output voltage of the adapter 60 can be directly supplied to the battery pack 20, and the battery pack 20 can be rapidly charged through the direct charging path.
The charging adjustment unit 40 is a boost adjustment unit for starting an operating state when the output voltage of the adapter 60 is insufficient to support the direct charging of the first battery and the second battery, and performing boost adjustment on the output voltage of the adapter 60 to supply power to the battery pack 20. The specific device of the charge adjusting unit 40 is not limited as long as the boost adjusting function can be achieved, and may be, for example, a supercharger.
The control unit 50 is configured to detect whether the output voltage of the adapter 60 meets the direct charging threshold range, and control the switching unit 30 and the charging adjustment unit 40 according to the detection result, so as to control the adapter 60 to directly charge the battery pack 20 when the output voltage of the adapter 60 meets the direct charging threshold range, and control the charging adjustment unit 40 to adjust the output voltage when the output voltage does not meet the direct charging threshold range. The specific device of the control unit 50 is not limited as long as the detection control function can be realized, and may be, for example, a control chip.
Therefore, the switch unit 30, the charging adjustment unit 40 and the control unit 50 form a charging circuit of the battery pack 20, and the battery pack 20 is charged in different charging modes according to the output voltages of different adapters 60, so that the charging safety of the battery pack 20 is ensured, the service life of the battery pack 20 is prolonged, and the charging speed is increased.
Optionally, when the first battery is connected in series with the second battery, the terminal device further includes a discharge adjustment unit, and the voltage output by the battery pack 20 is subjected to voltage regulation processing, such as voltage reduction processing of 1/2, and then is supplied to each module of the terminal device, so that it is possible to ensure that the supply voltage matches the working requirement of each module, and improve the stability of the terminal device. The specific components of the discharge regulating unit are not limited as long as the voltage regulating function can be achieved, and may include a switching DC-DC voltage converting circuit, such as a buck converting circuit.
A charging circuit composed of the switching unit 30, the charge adjusting unit 40, and the control unit 50, and a discharging circuit composed of the discharge adjusting unit will be described below.
Referring to fig. 11, the switching unit 30 includes a switching transistor Q1, the charging adjustment unit 40 includes a voltage booster B1, the control unit 50 includes a control chip U1, and the discharging adjustment unit includes a buck converter circuit B2. The base electrode of the switch tube Q1 is connected with the first control end of the control chip U1, the collector electrode of the switch tube Q1 is connected with the adapter 60, and the emitter electrode of the switch tube Q1 is connected with the anode electrode of the battery pack 20; the controlled end of the booster B1 is connected with the second control end of the control chip U1, the input end of the booster B1 is connected with the adapter 60, the boosting end of the booster B1 is connected with the anode of the battery pack 20, and the grounding end of the booster B1 is connected with the cathode of the battery pack. The input end of the buck conversion circuit B2 is connected with the positive pole of the battery pack 20, the grounding end of the buck conversion circuit B2 is connected with the negative pole of the battery pack 20, and the output end of the buck conversion circuit B2 is connected with a module corresponding to a terminal device. The detection terminal of the control chip U1 is connected to the detected terminal of the adapter 60.
During charging, the control chip U1 detects whether the output voltage of the adapter 60 satisfies the direct charging threshold range, and when the output voltage of the adapter 60 is in the direct charging threshold range, the control chip U1 controls the switching tube Q1 to connect the direct charging path of the battery pack 20 to charge the battery pack 20. When the output voltage of the adapter 60 is smaller than the direct charging threshold range, the control chip U1 controls the switching tube Q1 to be cut off and controls the supercharger B1 to start the supercharging function, and the supercharger B1 regulates the voltage output by the adapter 60 to charge the battery pack 20. During discharging, the voltage output by the battery pack 20 is regulated by the buck converter B2, and then output to the corresponding module of the terminal device.
