Fig. 1 is a schematic diagram of a partial structure of an electronic device according to the related art. Referring to fig. 1, an electronic device includes: the touch control layer 110, the backlight layer 120, the metal frame 130 and the liquid crystal display layer. The liquid crystal display layer includes a common electrode layer 141 multiplexed with the touch layer 110, the metal frame 130 is disposed on the back surface of the liquid crystal display layer, and the backlight layer 120 is disposed between the liquid crystal display layer and the metal frame 130. In this way, an equivalent capacitance is formed between the touch layer 110 and the metal frame 130. When a user touches a display screen of an electronic device, the voltage of the touch layer 110 will change periodically, and a voltage difference exists between the touch layer 110 and the metal frame 130, so that the backlight layer 120 deforms due to the expansion effect and poisson characteristic generated by the voltage difference, and the backlight layer 120 generates abnormal sound due to air vibration driven by deformation, thereby generating a howling problem, and being unfavorable for improving user experience.
In order to solve the above problems, embodiments of the present disclosure provide an electronic device, a control method thereof, and a computer-readable storage medium, which are described in detail below with reference to the accompanying drawings:
fig. 2 is a schematic diagram showing a partial structure of an electronic device according to an exemplary embodiment of the present disclosure, fig. 3 is an exploded schematic diagram showing a partial structure of an electronic device according to an exemplary embodiment of the present disclosure, and fig. 4 is a schematic diagram showing a partial structure of an electronic device according to an exemplary embodiment of the present disclosure. Referring to fig. 2 to 4 in combination, the electronic device includes: the touch screen comprises a touch screen 210, a liquid crystal display 220, a metal frame 230, a switch 240 and a controller 250.
The liquid crystal display layer 220 includes a common electrode layer 221 multiplexed with the touch layer 210. In this way, it is advantageous to reduce the thickness of the electronic device. In the embodiment of the present disclosure, since the touch layer 210 and the common electrode layer 221 are multiplexed, the related "connection relationship of the touch layer 210" is equal to the "connection relationship of the common electrode layer 221".
The metal frame 230 is provided on the back surface of the liquid crystal display layer 220, which gives a good mechanical strength to the display panel including the touch layer 210 and the liquid crystal display layer 220. The metal frame 230 may have a frame structure, and the metal frame 230 may wrap the back and side surfaces of the liquid crystal display layer 220.
The switch 240 is connected between the touch layer 210 and the metal frame 230. When the switch 240 turns on the touch layer 210 and the metal frame 230, no voltage difference exists between the touch layer 210 and the metal frame 230.
The controller 250 is connected to the switch 240, and the controller 250 is configured to: the control switch 240 turns on the touch layer 210 and the metal frame 230. Thus, no voltage difference exists between the touch layer 210 and the metal frame 230, and when the voltage of the touch layer 210 changes, the stretching effect and the poisson effect of other film layers between the touch layer 210 and the metal frame 230 cannot occur, abnormal sound cannot occur, the howling problem is solved, and the user experience is facilitated to be improved.
The controller 250 may be, for example, a CPU (Central Processing Unit ) or an AP (Application Processor, application processor) of the electronic device.
In some embodiments, referring to fig. 4, the electronic device provided in the embodiments of the present disclosure further includes: a distance sensor 260 connected to the controller 250; the controller 250 is specifically configured to: receiving a distance signal detected by the distance sensor 260; in response to the distance signal corresponding to the distance signal being less than the reference threshold, the control switch 240 turns on the touch layer 210 and the metal frame 230.
For example, by detecting a distance signal by the distance sensor 260, the controller 250 may determine from the distance signal that the user is near the electronic device when the user is on the phone or in voice. At this time, the control switch 240 conducts the touch layer 210 and the metal frame 230, so that there is no voltage difference between the touch layer 210 and the metal frame 230, and thus no howling problem is generated, and further, when the user approaches the electronic device, no abnormal sound is heard, which is beneficial to improving user experience.
Illustratively, the distance sensor 260 includes at least one of an optical displacement sensor, a linear proximity sensor, and an ultrasonic displacement sensor. Illustratively, the distance sensor 260 is disposed on top of the electronic device, e.g., the distance sensor 260 is disposed on top of the cell phone. Illustratively, the distance sensor 260 is provided on the side of the electronic device. The distance sensor 260 according to the present disclosure may multiplex the original distance sensor 260 of the electronic device.
In some embodiments, the controller 250 is further configured to:
in response to the distance signal corresponding to the distance greater than or equal to the reference threshold, the switch 240 is controlled to disconnect the touch layer 210 and the metal frame 230. Thus, when the electronic device is far away from the user, the user cannot easily hear the abnormal sound, and at this time, the controller 250 may control the switch 240 to disconnect the touch layer 210 and the metal frame 230.
Fig. 5 is a block diagram illustrating the connection of a local structure of an electronic device according to an exemplary embodiment of the present disclosure. In some embodiments, the switching element 240 includes a power switching tube 241, and the power switching tube 241 includes a first pole connected to the touch layer 210, a second pole connected to the metal frame 230, and a gate connected to the controller 250. Illustratively, the controller 250 is specifically configured to: outputting a conducting signal to the gate in response to the distance corresponding to the distance signal being smaller than the reference threshold, so that the switch 240 conducts the touch layer 210 and the metal frame 230; in response to the distance corresponding to the distance signal being greater than or equal to the reference threshold, a turn-off signal is output to the gate, so that the switch 240 turns off the touch layer 210 and the metal frame 230. The power switch tube is easy to obtain and convenient to control.
The power switch tube 241 may be an N-type MOS tube or a P-type MOS tube. Taking an N-type MOS transistor as an example, a source of the N-type MOS transistor may be connected to the touch layer 210, and a drain of the N-type MOS transistor is connected to the metal frame 230. At this time, the on signal is a high level signal, and the off signal may be a low level signal.
In some embodiments, with continued reference to fig. 2, 3 and 4, the liquid crystal display layer 220 includes a color filter 222, a liquid crystal layer 223, a common electrode layer 221 and a TFT panel 224, which are sequentially stacked, and the switching element 240 is provided to the TFT panel 224. It is understood that the TFT plate 224 includes a substrate and TFTs (Thin Film Transistor, thin film transistors) formed on the substrate, by which whether or not the common electrode layer 221 applies a voltage to the liquid crystal layer 223 to drive the liquid crystal to rotate. The TFT board 224 can have an idle position, and by arranging the switch element 240 on the TFT board 224, not only is the switch element 240 convenient to be connected with the touch layer 210, but also the space of the TFT board 224 is fully utilized, so that other design space is prevented from being increased. Illustratively, the color filter plate 222 may be color filter glass and the TFT plate 224 may be TFT glass.
In some embodiments, with continued reference to fig. 3 and 4, the electronic device further includes a flexible circuit board 270, the flexible circuit board 270 being connected to the switch 240 and the controller 250. In other words, the switching element 240 is connected to the controller 250 through the flexible wiring board 270. In this way, the flexible circuit board 270 is convenient to adapt to different shapes of space inside the electrical device, and connection of the switch 240 and the controller 250 is facilitated.
In some embodiments, referring to fig. 2 and 4 in combination, the electronic device further includes a backlight layer 280 disposed between the metal frame 230 and the TFT plate 224; the backlight layer 280 includes a light bar 281 connected to the flexible wiring board 270, and the light bar 281 is connected to the metal frame 230.
