According to single switch S in the difference control switch component 304 ' between the target charging voltage and output voltage of current charging stage
Conducting and shutdown, and then control the conducting of route between N*M wireless charging circuit 104 and battery 302 simultaneously.
For example, when the output voltage of target charging voltage and any wireless charging circuit 104 in N*M wireless charging circuit
Between difference be less than preset voltage threshold when, show at least exist a wireless charging circuit 104, receiving coil 1042
Generated open-circuit voltage is not much different with target charging voltage between two end electrodes, i.e. the reception line of the wireless charging circuit 104
Circle 1042 is good with the transmitting coil position positive relationship of transmit circuit in wireless charging device.Control module 308 controls at this time
Switch S closure, then the route between wireless charging circuit 104 and battery 302 all in flexibility AMOLED display panel 10 is led
It is logical, so that all wireless charging circuits 104 charge jointly for battery 302.
On the contrary, assume target charging voltage in N*M wireless charging circuit each wireless charging circuit 104 it is defeated
The difference between voltage is not less than preset voltage threshold out, shows that there is no receive line in flexible AMOLED display panel 10
The good wireless charging circuit 104 of transmitting coil position positive relationship of circle 1042 and transmit circuit in wireless charging device.This
When control module 308 control switch S be held off, namely without wireless charging circuit 104 be that battery 302 charges.User
It can make in N*M wireless charging circuit by adjusting the placement position between charging equipment 40 and wireless charging device
At least one wireless charging circuit 104 meets voltage conditions, then can make all wireless charging circuits 104 jointly is battery
302 charge.
Fig. 5 is the block diagram according to another charging equipment shown in an illustrative embodiments.With shown in Fig. 3 wait fill
Electric equipment 30 the difference is that, it includes multiple switch that charging equipment 50 shown in fig. 5, which further provides switch block,
One embodiment.
With reference to Fig. 5, the switch block 304 " of charging equipment 50 includes multiple switch: S1、S2、S3、…、SN*M.Similarly,
Switch S1、S2、S3、…、SN*MSuch as or controllable transistor (such as metal-oxide-semiconductor) controllable switch device.Wherein, switch S1、
S2、S3、…、SN*MIt is connected to N*M wireless charging circuit 104, and each switch SkWith the wireless charging electricity being correspondingly connected with
Parallel with one another, any positive integer of the k between 1~N*M between the series arm that road 104 is constituted.Each series arm after parallel connection
It is connect with battery 302.
Hold above-mentioned, output voltage of the detection module 306 for N*M wireless charging circuit 104 of detection respectively.Control module
308 for according to more in the difference control switch component 304 " between the target charging voltage and output voltage of current charging stage
A switch S1、S2、S3、…、SN*MConducting and shutdown, and then independently control N*M wireless charging circuit 104 and battery 302
Between route conducting.
For example, when the output electricity of target charging voltage and a part of wireless charging circuit 104 in N*M wireless charging circuit
When difference between pressure is less than preset voltage threshold, show the receiving coil 1042 and nothing of the part wireless charging circuit 104
The transmitting coil position positive relationship of transmit circuit is good in line charge electric installation.The control of control module 308 at this time is connected to
The part wireless charging circuit 104 closes the switch, and control is connected to remaining wireless charging circuit 104 for being unsatisfactory for voltage conditions
Switch be held off so that the wireless charging circuit 104 for meeting voltage conditions in flexibility AMOLED display panel 10 is total
It is all that battery 302 charges.
