For example, when the target identifier is a two-dimensional code, the terminal 102 can scan the two-dimensional code displayed by the terminal 101.
Various non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings.
exemplary method
referring to fig. 2, a method for displaying a logo in an embodiment of the present invention is shown. In this embodiment, the method may include, for example, the steps of:
s201: and when the display screen of the first terminal is in a black screen state, detecting whether an ultrasonic signal sent by a second terminal is received.
In this embodiment, when the first terminal is in the sleep state, that is, the display screen of the first terminal is in the black screen state, the ultrasound acquisition device in the first terminal may maintain a normal operating state, that is, the ultrasound acquisition device in the terminal may detect the ultrasound signal sent by the second terminal within the preset range of the terminal. Specifically, in a possible implementation manner, S201 specifically includes: and judging whether a display screen of the terminal is in a black screen state, and if so, periodically detecting whether the ultrasonic signal sent by the second terminal is received, for example, an ultrasonic acquisition device in the terminal can detect whether the ultrasonic signal sent by the second terminal is received every other one second.
It should be noted that the ultrasonic signal in this embodiment may be understood as an ultrasonic wave carrying information (such as an IP address).
S202: and if the ultrasonic signal is received and meets a preset condition, awakening a display screen of the terminal.
In this embodiment, after the terminal receives the ultrasonic signal sent by the second terminal, it may be determined whether the ultrasonic signal meets a preset condition, and if the ultrasonic signal meets the preset condition, it is described that the ultrasonic signal is a trigger instruction for triggering the terminal to display the target identifier, then a subsequent operation may be performed in response to the ultrasonic signal, for example, a display screen of the terminal may be awakened first, so that the target identifier may be displayed.
It should be noted that, in this embodiment, the preset condition may be that the target information corresponding to the ultrasonic wave is the same as the preset information. Specifically, when the preset condition is that the target information corresponding to the ultrasonic wave is the same as the preset information, S202 specifically includes: if the ultrasonic signal is received, analyzing the ultrasonic signal to obtain target information corresponding to the ultrasonic wave; judging whether the target information meets a preset condition or not, wherein the preset condition is that the target information is the same as preset information; and if the target information meets the preset condition, awakening the display screen of the terminal.
it can be understood that after the ultrasonic signal sent by the second terminal is acquired, the target information corresponding to the ultrasonic signal may be extracted first, where the target information is information carried in the ultrasonic information; and comparing the target information with preset information, if the target information corresponds to the preset information, it is indicated that a second terminal needs to acquire a target identifier in a preset range of the current first terminal, that is, the first terminal needs to display the target identifier so that other second terminals can acquire the target identifier, and therefore, a display screen of the first terminal needs to be awakened first at this time so as to facilitate subsequent operations.
S203: and displaying a target identifier in the display screen so that the second terminal can acquire the target identifier.
after the display screen of the first terminal is awakened, the target identifier can be displayed in the display screen, so that the second terminal can acquire the target identifier and perform related operations according to the target identifier. It should be noted that, in this embodiment, the target identifier may be an identifier for describing information, for example, the display form of the target identifier may include a two-dimensional code, that is, the target identifier may be a two-dimensional code.
in this embodiment, the target identifier may be pre-stored by the terminal, or may be generated by the first terminal. It should be noted that, when the target identifier is a condition generated by the first terminal, the first terminal may generate the target identifier before waking up the display screen of the first terminal after determining that the voice information meets the preset condition, or may generate the target identifier after waking up the display screen of the first terminal, where the generation time of the target identifier is not limited in this embodiment.
When the information recorded in the target identifier is different, the other terminals acquire the target identifier and perform different operations according to the target identifier. The following will respectively describe the case where the target identifier is a netmeeting link, a terminal pairing code, a synchronization instruction, and a control instruction:
First, a case when the target identification includes a network conference connection is introduced. In one implementation, the target identifier includes a network conference link, and S203 may include: and displaying a target identifier in a display screen of the second terminal so that the second terminal can acquire the target identifier and enter a network conference corresponding to the network conference connection according to the network conference link in the target identifier.
specifically, when the target identifier records information of the web conference connection, after the second terminal obtains the target identifier shown by the first terminal, for example, the target identifier is a two-dimensional code, and after the second terminal scans the two-dimensional code, the second terminal may obtain the web conference link from the target identifier and join the web conference link in the web conference according to the web conference link.
Next, a case when the target identifier includes a terminal pairing code is introduced. In one implementation, the target identifier includes a terminal pairing code, and S203 may include: and displaying the target identification in the display screen so that other terminals can acquire the target identification, and pairing with the terminal according to the terminal pairing code in the target identification.
Specifically, when the target identifier records information of the terminal pairing code, after the second terminal acquires the target identifier displayed by the first terminal, for example, the target identifier is a two-dimensional code, and after the second terminal scans the two-dimensional code, the second terminal may acquire the terminal pairing code from the target identifier and pair with the terminal according to the terminal pairing code.
Next, a case when the target identifier includes a synchronization instruction is described. In one implementation, the target identifier includes a synchronization instruction, and S203 may include: and displaying a target identifier in the display screen so that the second terminal can acquire the target identifier, and projecting a display interface of the second terminal to the display screen of the first terminal according to the synchronous instruction in the target identifier.
Specifically, when the target identifier records information of the synchronization instruction, after the second terminal acquires the target identifier displayed by the first terminal, for example, the target identifier is a two-dimensional code, and after the second terminal scans the two-dimensional code, the second terminal may acquire the synchronization instruction from the target identifier and perform interface synchronization with the first terminal according to the synchronization instruction, so that the content displayed in the display screen of the first terminal is the same as the content displayed in the second terminal, that is, the contents displayed in the first terminal and the second terminal are synchronized.
finally, a case when the target identification includes a control instruction is described. In one implementation, the target identifier includes a control instruction, and S203 may include: and displaying a target identifier in the display screen so that the first terminal can acquire the target identifier and control the terminal according to the control instruction in the target identifier.
specifically, when the target identifier records information of the control instruction, the second terminal obtains the target identifier displayed by the first terminal, for example, the target identifier is a two-dimensional code, and after the second terminal scans the two-dimensional code, the second terminal can obtain the control instruction from the target identifier and control the terminal according to the control instruction, for example, a user can control a key in the second terminal or click on another terminal to control the first terminal to perform a corresponding operation, for example, the user can control a volume increase key in the second terminal to control the volume increase of the first terminal.
It is thus clear that, in this application, when the display screen of first terminal is in the black screen state, if the ultrasonic signal that the second terminal sent is received, just ultrasonic signal satisfies the preset condition, then awakens up the display screen of first terminal and is in show target identification in the display screen, so that the second terminal obtains target identification.
