In some embodiments of the present application, an electronic device is proposed, fig. 1 shows a schematic structural diagram of the electronic device according to an embodiment of the present application, fig. 2 shows one of circuit diagrams of a power supply circuit according to an embodiment of the present application, and as shown in fig. 1 and fig. 2, the electronic device 100 includes:

In an embodiment of the present application, the electronic device 100 includes a display screen 102, a power supply circuit 104, a detection circuit 108, and a controller 110, where the display screen 102 is specifically an OLED display screen, and the power supply circuit 104 is configured to supply power to the display screen 102. Specifically, the power supply circuit 104 includes a switching circuit 106, and the switching circuit 106 includes a first input terminal connected to a first electrical signal and a second input terminal connected to a second electrical signal. Wherein the first electrical signal is the electrical signal provided directly by the bus.

Specifically, in the work engineering of the electronic device 100, under the condition that the power supply is normal, the first input end and the output end of the switch circuit 106 are communicated, and at this time, the display screen 102 is supplied with power through the first electrical signal, that is, the bus direct-current signal. During the display process of the display screen 102, the detection circuit 108 detects the working parameters of the display screen 102 in real time, such as display brightness information, signal fluctuation information, etc., and determines the working state of the display screen 102 according to the working parameters, and controls the switch circuit 106 to switch the power supply signal. If the display screen 102 works normally, the first input end and the output end of the off circuit are kept communicated, and power is supplied through the first electric signal. If the display screen 102 works abnormally, if display fluctuation occurs, and if brightness appears in a flickering mode, the working state of the display screen 102 is affected by the fluctuation of the bus signal, at the moment, the control switch circuit 106 is switched to be communicated with the second input end and the output end, and power is supplied to the display screen 102 through the second electric signal, so that the display flicker caused by the fluctuation of the power supply signal of the bus is avoided.

By setting the switch circuit 106 and the detection circuit 108, in the working process of the display screen 102, the working parameters of the display screen 102 are detected in real time, the conduction mode of the switch circuit 106 is switched according to the working parameters, so that the power supply signals of the display screen 102 are switched, when signal fluctuation occurs in a bus, the power supply can be switched to other power supply signals in time to supply power for the display screen 102, display fluctuation caused by bus signal fluctuation is avoided, and the display effect of the display screen 102 is ensured.

In some embodiments of the present application, the power supply circuit 104 further comprises:

the input end of the first transforming device 1042 is connected to a power supply signal, the first output end of the first transforming device 1042 is connected to the first input end of the switch circuit 106, the second output end of the first transforming device 1042 is connected to the second input end of the switch circuit 106, and the first transforming device 1042 is configured to adjust the power supply signal into a first electrical signal and a second electrical signal.

In this embodiment, the first voltage transforming device 1042 is a DC-DC converter, and is configured to adjust the voltage of the power supply signal of the bus to the first electrical signal or the second electrical signal. The first transformer 1042 includes two output ends, specifically a first output end and a second output end, the first output end is connected to the first input end of the switch circuit 106, when the switch circuit 106 is switched to the first input end to be communicated with the output end, the first transformer 1042 adjusts the power supply signal VBUS of the bus into the first signal VPH and then directly outputs the first signal VPH to the screen, which is also equivalent to that the power supply signal of the bus directly supplies power to the display screen 102.

The second output end of the first transformer 1042 is connected to the second input end of the switch circuit 106, which is specifically a charging path, and outputs a second signal VBAT, and when the switch circuit 106 switches to the second input end to be communicated with the output end, the display screen 102 is powered by the VBAT.

The embodiment of the application switches the conduction mode of the switch circuit 106 according to whether the display of the display screen fluctuates or not, so that the power supply signal of the display screen 102 is switched, the display fluctuation caused by the fluctuation of the bus signal is avoided, and the display effect of the display screen 102 is ensured under the condition of not increasing the power consumption.

In some embodiments of the present application, the power supply circuit 104 further comprises:

a first switch tube 1044, a first end of the first switch tube 1044 is connected to the second output end of the first transformer 1042, and a second end of the first switch tube 1044 is connected to the second input end of the switch circuit 106;

and a capacitive element 1046, wherein a positive electrode of the capacitive element 1046 is connected to the second end of the first switch tube 1044, and a negative electrode of the capacitive element 1046 is grounded.

In this embodiment, the power supply circuit 104 includes a first switch tube 1044 and a capacitive element 1046, where the first switch tube 1044 is a charge/discharge management switch tube of the capacitive element 1046, and the first switch tube 1044 may be an MOS tube.

During operation, the detection circuit 108 detects the operating parameters of the display screen 102, such as the brightness or electrical signal of the display screen 102, and determines whether the display screen 102 has display fluctuation according to the operating parameters of the display screen 102. Under normal operation of the display screen 102, the switch circuit 106 connects the first signal VPH to supply power to the display screen 102. When the power supply signal VBUS of the bus fluctuates, VPH may also fluctuate synchronously, which may cause the display effect of the display screen 102 to fluctuate. When the detection circuit 108 detects the fluctuation, the switching circuit 106 is controlled to switch the conduction mode, and the first switching tube 1044 is controlled to be conducted, at this time, the display screen 102 is supplied with power through the second signal VBAT, and the second signal VBAT is clamped due to the existence of the capacitive element 1046, so that the VBAT is not fluctuated obviously, thereby avoiding the fluctuation of the display effect and improving the display stability of the display screen 102.

It can be understood that when the display screen 102 is powered by the second signal VBAT, the voltage of the capacitive element 1046 may drop because it is in a discharge state, and therefore, when VBUS returns to normal, the switching circuit 106 switches back to the state powered by the first signal VPH.

a second switch tube 1062, a first end of the second switch tube 1062 being connected to the first output end of the first transformer 1042, a second end of the second switch tube 1062 being connected to the display screen 102, and a control end of the second switch tube 1062 being connected to the controller 110;

In this embodiment, the switch circuit 106 includes a second switch tube 1062 and a third switch tube 1064, and the second switch tube 1062 is connected in series between the first output end of the first voltage transformation device 1042 and the display screen 102, and is used for controlling on/off between the first signal VPH and the display screen 102. The third switch tube 1064 is connected in series between the second output end of the first transformer 1042 and the display screen 102, and is used for controlling on/off of the second signal VBAT and the display screen 102.

Specifically, if the power supply signal VBUS of the bus fluctuates, the first signal VPH also fluctuates correspondingly, at this time, the second switch tube 1062 is turned off, the first switch tube 1044 and the third switch tube 1064 are turned on, and power is supplied to the display screen 102 through the second signal VBAT, and due to the clamping effect of the capacitive element 1046, the fluctuation of the display effect caused by the signal fluctuation can be avoided, so that the display effect is improved.

A second photosensor 1084 is located in the area under the screen covered by the display screen 102 for obtaining screen brightness. Since the ambient light also irradiates the screen to increase the screen brightness, the screen brightness obtained by the second photosensor 1084 actually consists of screen brightness, that is, the self-luminous brightness of the screen and the ambient brightness. In the actual working process, a plurality of ambient light intensities are collected by the first photosensitive sensor 1082, and a screen brightness is collected by the second photosensitive sensor 1084 while each ambient light intensity is collected.

Thus, the data set M1 ═ G1, G2, G3 … … ] of the screen brightness and the data set M2 ═ B1, B2, B3 … … of the ambient light brightness corresponding thereto one by one were obtained. By determining the difference between M1 and M2, a data set M [ N1, N2, N3 … … ] reflecting the screen luminance change with time can be obtained, and fourier transform is performed on the array M to obtain a curve reflecting the screen luminance change, and whether display fluctuation (namely, luminance fluctuation) occurs or not can be determined according to the curve, so that when the fluctuation occurs, the switch circuit 106 is controlled to switch to a signal for supplying power to the screen, and the screen display fluctuation caused by the signal fluctuation is eliminated.

and step 406, controlling the first switching tube and the third switching tube of the electronic device to be conducted and controlling the second switching tube of the electronic device to be cut off under the condition that the change of the N luminescent brightness of the display screen is matched with the preset change threshold.

In an embodiment of the application, the electronic device includes a display screen, a power supply circuit, a detection circuit, and a controller, where the display screen is specifically an OLED display screen, and the power supply circuit is configured to supply power to the display screen. Specifically, the power supply circuit comprises a switch circuit, the switch circuit comprises a second switch tube and a third switch tube, and the second switch tube is connected in series between the first output end of the first voltage transformation device and the display screen and is used for controlling the connection and disconnection between the first signal VPH and the display screen.

In the working process of the electronic equipment, the preset duration is taken as a detection period, and the ambient light brightness and the screen brightness are detected in real time. Specifically, N ambient light intensities and N screen intensities are detected in each detection cycle, that is, in each preset time period, and one screen intensity is collected at the same time as one ambient light intensity is collected at each time, whereby a data set M1 ═ G1, G2, G3 … … Gn ] of the screen intensities and a data set M2 ═ B1, B2, B3 … … Bn of the ambient light intensities in one-to-one correspondence therewith are obtained.
