The display control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a wireless charging circuit according to an embodiment of the present disclosure. As shown in fig. 1, the wireless charging circuit 10 includes a charging chip module 11 and a first capacitor 12; the first capacitor 12 is electrically connected to the output end of the charging chip module 11, and is configured to filter the output voltage of the charging chip module 11, that is, the first capacitor 12 serves as a filter capacitor of the charging chip module 11; the charging chip module 11 is configured to convert an alternating current transmitted from a power supply into a direct current and adjust the direct current to a voltage required for high-voltage charging of the electronic device;
the wireless charging circuit 10 further includes at least one first circuit module 13 and at least one second capacitor 14, where the first circuit module 13 is a different circuit module from the charging chip module 11, that is, the first circuit module 13 is another circuit module in the wireless charging circuit;
the output end of each first circuit module 13 is electrically connected to a second capacitor 14, and the second capacitor 14 is configured to filter the output voltage of the first circuit module 13, that is, the second capacitor 14 serves as a filter capacitor corresponding to the first circuit module 13;
in the wireless charging circuit 10, one end of the first capacitor 12 is electrically connected to the output end of the charging chip module 11, one end of the second capacitor 14 is electrically connected to the output end of the first circuit module 13, the other end of the first capacitor 12 is electrically connected to one end of the second capacitor 14, and the other end of the second capacitor 14 is grounded, so that the first capacitor 12 and the second capacitor 14 are connected in series, and the withstand voltage values at two ends of the serially connected capacitors are the sum of the withstand voltage values thereof, which can satisfy the range of higher working voltage.
The first capacitor 12 and the second capacitor 14 are connected in series, so that the voltage originally loaded on the first capacitor 12 can be shared by the first capacitor 12 and the second capacitor 14, and after the first capacitor 12 and the second capacitor 14 are connected in series, the voltage value higher than that of the output end of the charging chip module 11 can be borne by the first capacitor 12 which is not connected in series with the second capacitor 14, and the voltage withstanding value of a single capacitor does not need to be increased, so that the requirement of the capacitor voltage withstanding value of a high-voltage charging scheme can be met.
For example, two capacitors C1 and C2 with the same parameters are connected in series, wherein the maximum voltage withstanding value that the capacitor C1 can bear is U1, and the maximum voltage withstanding value that the capacitor C2 can bear is U2, and according to the characteristics of the series circuit, the total voltage of two series-connected elements is equal to the sum of the voltages at the two ends of the two series-connected elements, i.e., the maximum voltage withstanding value that the two series-connected capacitors can bear.
It will be appreciated that the manner of connecting the first capacitor 12 in series with the second capacitor 14, while not raising the voltage resistance of the individual capacitors, is equivalent to raising the voltage resistance of the first capacitor.

meanwhile, the first capacitor 12 is electrically connected to the first output terminal of the rectifier 111;
the circuit further includes a third capacitor 17, wherein one end of the third capacitor 17 is electrically connected to the second output terminal of the low dropout regulator Q1, and is configured to filter the output voltage of the low dropout regulator Q1.
Optionally, in another embodiment, the other end of the third capacitor 17 is electrically connected to one end of one of the second capacitors 14, that is, the third capacitor 17 is also connected in series with the corresponding second capacitor 14, so that the voltage originally loaded on the third capacitor 17 can be shared by the third capacitor 17 and the second capacitor 14, and after the third capacitor 17 is connected in series with the second capacitor 14, the voltage value higher than that of the output end of the low dropout linear regulator Q1 can be borne by the third capacitor 17 that is not connected in series with the second capacitor 14, and the requirement for the voltage withstanding value of the capacitor of the high-voltage charging scheme can be met without increasing the voltage withstanding value of a single capacitor.
The above embodiment enables the voltage withstanding value of the filter capacitor at the output circuit of the rectifier 111 and/or the filter capacitor at the output circuit of the low dropout regulator Q1 to be improved, and can satisfy a higher charging voltage than the first capacitor 12 provided separately.
Alternatively, in an embodiment, the other end of the first capacitor 12 and the other end of the third capacitor 17 are electrically connected to one end of the same second capacitor 14. That is, in the present embodiment, the filter capacitor of the same first circuit module is connected in series with the first capacitor and the third capacitor at the same time, and the effect of increasing the withstand voltage of the first capacitor and the third capacitor can be achieved only by using one second capacitor.
In practical applications, the charging chip module 11 further includes a processor, a power driving and biasing circuit, and the like.
