Referring to fig. 1 to 5, a fourth aspect of the embodiments of the present application provides a control method for a display device, where when a power supply unit is provided in one, in order to ensure a display effect of the display device, a charging loop and a discharging loop of the power supply unit are in a normally closed state.
When the number of the power supply units is two or more, for convenience of description, the embodiment will be described in detail by taking the example that two power supply units are provided, and when a plurality of power supply units are provided, the main principle is similar to that when two power supply units are provided. The two power supply units include a first power supply unit 10 and a second power supply unit 21, and the control method of the display device includes:
acquiring a first remaining capacity of the first power supply unit 10 and a second remaining capacity of the second power supply unit 21;
when the first remaining capacity is smaller than the minimum first capacity threshold, controlling a charging loop of the first power supply unit 10 to be closed and a discharging loop of the first power supply unit to be opened;
when the first remaining capacity is equal to the maximum first capacity threshold, controlling the charging loop of the first power supply unit 10 to be disconnected;
when the second remaining capacity is smaller than the minimum second capacity threshold, controlling a charging loop of the second power supply unit 21 to be closed and a discharging loop of the second power supply unit to be opened;
and when the second remaining capacity is equal to the maximum second capacity threshold, controlling the charging loop of the second power supply unit 21 to be disconnected.
In a specific embodiment, the minimum first power threshold and the minimum second power threshold are preset power alarm critical values, for example, the minimum first power threshold and the minimum second power threshold may be set to be less than 20% of the total power of the power supply unit, specifically, may be set to be 10% or 5% of the total power of the power supply unit, and the like, so as to prompt the situation that the remaining power of the power supply unit is insufficient. The maximum first power threshold is a full power value of the first power supply unit 10, and the maximum second power threshold is a full power value of the second power supply unit 21. By arranging two power supply units, at least one power supply unit can be ensured to be used for supplying power, and the power supply effect is ensured.
In an optional embodiment, when the discharging circuit of the first power supply unit 10 is opened, the discharging circuit of the second power supply unit 21 is controlled to be closed, and the charging circuit of the second power supply unit 21 is controlled to be opened; when the discharging circuit of the second power supply unit 21 is opened, the discharging circuit of the first power supply unit 10 is controlled to be closed, and the charging circuit of the first power supply unit 10 is controlled to be opened. The two power supply units work in sequence, so that a discharge loop of at least one power supply unit in the two power supply units is closed, and the power supply effect is ensured.
In the control method of the display device provided in this embodiment, during actual use, when the first discharging circuit 19 is closed, the first charging circuit 11 is opened, and at this time, the first power supply unit 10 is in a power supply state, the first remaining power of the first power supply unit 10 is monitored in real time, and when the first remaining power is smaller than the minimum first power threshold, a pulse signal is sent to enable the adjusting device 24 to control the first discharging circuit 19 to be opened, and the first charging circuit 11 is closed, and at this time, the first power supply unit 10 is in a charging state. Meanwhile, the second discharging circuit 20 is closed, and the second charging circuit 22 is opened, so that the second power supply unit 21 is in a power supply state, and the second remaining capacity of the second power supply unit 21 is monitored in real time; in this process, when it is detected that the first remaining capacity is equal to the maximum first capacity threshold, a pulse signal is sent out to enable the adjusting device 24 to control the first charging circuit 11 to be disconnected, so as to avoid charging in the process. When the second remaining capacity is smaller than the minimum second capacity threshold, a pulse signal is sent out to enable the adjusting device 24 to control the second discharging circuit 20 to be opened, the second charging circuit 22 is closed, and the second power supply unit 21 is in a charging state. At the same time, the first discharging circuit 19 is closed and the first charging circuit 11 is opened, so that the first charging unit is in a power supply state, and when the second remaining capacity is detected to be equal to the maximum second capacity threshold value, a pulse signal is sent to open the second charging circuit 22, so as to circulate. The cooperative work of each power supply unit is realized, so that the service life of the power supply unit is ensured.

Also, the terms "comprises," "comprising," and "having," as well as any variations thereof or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
