Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Based on the above problems, embodiments of the present application provide a display screen connection detection method and apparatus, a computer-readable storage medium, and a terminal, which can effectively improve the use efficiency of a display screen of the terminal. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a first display screen connection detection method according to an embodiment of the present disclosure. The display screen connection detection method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The terminal includes at least a circuit board and a display screen. The circuit board is provided with an electric signal output port, the display screen is provided with an electric signal input port, and the circuit board is electrically connected with the display screen through the output port and the input port. The specific process of the display screen connection detection method can be as follows:
101. when detecting that the circuit board is electrically connected with the display screen, acquiring the input current and the input voltage of the display screen.
In this embodiment, the circuit board may be a motherboard. Specifically, the main board may be installed inside the terminal, and the main circuit system constituting the computer is installed on the main board, and includes various control chips, keyboard and board control switch interfaces, indicator light connectors, expansion slots, and dc power supply connectors for the main board and the plug-in card.
In this embodiment, the display screen may be a display of the terminal device, and the display is an input and output device belonging to the terminal. The Display can be classified into a CRT (cathode-ray tube Display), an LCD (liquid crystal Display), an OLED (Organic Light-Emitting Diode), and the like. The electronic document display tool is a display tool which displays a certain electronic document on a screen through a specific transmission device and reflects the electronic document to human eyes.
The trigger circuit board and the display screen can be electrically connected in various ways, for example, by turning on a terminal power supply and touching the terminal screen. Specifically, the circuit board is electrically connected with the display screen, namely the circuit board supplies power to the display screen, so that the display screen can start to work.
Specifically, when detecting that the circuit board is electrically connected with the display screen, whether the user performs the opening operation on the terminal can be detected. For example, when it is detected that the user turns on the terminal power supply, the circuit board may be triggered to be electrically connected to the display screen, and at this time, the display screen may be switched from the off state to the on state.
Furthermore, when the circuit board is detected to be electrically connected with the display, the input current and the input voltage of the display screen can be acquired. In some embodiments, before the obtaining of the input current and the input voltage of the display screen, the following process may be further included:
detecting whether the display screen displays an image picture or not;
if yes, executing the step of acquiring the input current and the input voltage of the display screen;
if not, triggering a vibrator to vibrate to prompt that display abnormity exists.
Specifically, after the circuit board is electrically connected with the display screen, the power can be supplied to the display screen, so that the display screen starts to work and display image pictures. After the circuit board is electrically connected with the display screen, whether the display screen displays image pictures or not can be detected. The image frames may be different image frames displayed according to different operations of the user on the terminal.
For example, the operation of the user on the terminal may be to turn on a terminal power button, and when the operation of the user is detected to be to turn on the terminal button, the image screen displayed on the terminal display screen may be a lock screen image interface.
When the display screen is detected to start displaying the image picture, the input current and the input voltage of the display screen can be acquired. Specifically, the input current and the input voltage of the display screen can be obtained by detecting a current value and a voltage value at an input interface of the display screen, the detected current value can be the input current, and the detected voltage can be the input voltage.
For example, if it is detected that the current value of the input interface of the display screen may be 1A (ampere) and the voltage value may be 10V (volt), the input current of the display screen may be 1A and the input voltage may be 10V.
When the display screen is detected to be still in a closed state, namely no image picture is displayed, the mobile phone vibrator can be triggered to start vibrating, and the user terminal is prompted to display abnormal conditions. Specifically, the vibration mode of the vibrator may be various, and for example, the vibration mode may be a continuous vibration. Wherein, the continuous vibration may be continuous vibration at the same vibration frequency within a set time period, and the like.
For example, when it is detected that the display screen is in the off state, the terminal may prompt the user that the terminal displays an abnormality by turning on the continuous vibration mode. In the embodiment, the user can be prompted that the terminal is abnormal through vibration, so that the user can conveniently send the terminal for repair in time.
102. An output voltage of the circuit board is determined from the input current.
Specifically, after determining the input current of the input port of the display screen, the output voltage of the output port of the circuit board can be determined according to the input current.
In some embodiments, the step of "determining the output voltage of the circuit board according to the input current" may further include the following process:
matching a voltage at a target sample number from a preset relationship library based on the input current as an output voltage of the circuit board, wherein the preset relationship library comprises: and the corresponding relation between the plurality of sample input currents of the display screen and the plurality of sample output voltages of the circuit board.
Specifically, a relational library of current and voltage is obtained, which may include circuit board output voltage corresponding to display screen input current. Because the power of the display screen is constant, the output voltage of the circuit board can be correspondingly changed when the circuit board outputs different currents.
The relational database can be obtained in advance according to experimental data and stored on a circuit board of the mobile terminal. For example, after determining the input current, the output voltage of the circuit board may be looked up in a relational library based on the input current.
103. And determining the resistance value between the output port and the input port when the circuit board is electrically connected with the display screen according to the input current, the input voltage and the output voltage.
In this embodiment, after the input current and the input voltage of the display screen are obtained, processing may be performed according to the obtained input current and the obtained input voltage, so as to obtain a resistance value between the circuit board and the electrical connection of the display screen. Specifically, the circuit board may include an output port, the display screen may include an input port, and the resistance value may be a connection resistance value between the output port of the circuit board and the input port of the display screen.
In some embodiments, the step of "determining the resistance value according to the input current and the input voltage" may include the following process:
performing difference value operation processing based on the input voltage and the output voltage to obtain a voltage difference value;
and calculating to obtain the resistance value according to the voltage difference value and the input current.
Specifically, the input current, the input voltage and the output voltage are processed according to a preset rule to obtain a processing result. The preset rule may be a calculation method, for example, the calculation method may be: rc ═ Ve-Vq)/Iq. Wherein Rc may be represented as a resistance value, Ve may be represented as an output voltage of the circuit board, Vq may be an input voltage at the display screen interface, and Iq an input current at the display screen interface. After the input current, the input voltage and the output voltage are obtained, calculation can be performed according to the calculation mode to obtain the resistance value.
For example, the input current Iq may be acquired as 1A, the input voltage Vq may be acquired as 10V, the output voltage Ve may be acquired as 15V, and the resistance value Rc may be calculated as 5 Ω (ohm) according to a preset calculation formula Rc ═ Ve-Vq)/Iq.
104. And comparing the resistance value with a preset threshold value to obtain a comparison result.
Specifically, the resistance value is compared with a preset threshold value. The preset threshold value can be set according to the actual use of the terminal, and the preset threshold value can ensure that the resistance value of the display screen of the terminal in the working process is below the preset threshold value and cannot influence the use performance of the terminal.
After the resistance value is calculated, the resistance value is compared with a preset threshold value, and a comparison result can be obtained. For example, the resistance value may be greater than a preset threshold value, less than a preset threshold value, or equal to a preset threshold value.
105. And judging whether the connection between the circuit board and the display screen is abnormal or not according to the comparison result.
Specifically, whether the connection between the circuit board and the display screen is abnormal or not can be judged according to the comparison result of the resistance value and the preset threshold value.
In some embodiments, the comparison result may include a plurality of types, and thus the step of "determining whether there is an abnormality in the connection between the circuit board and the display screen according to the comparison result" may include the following steps:
if the resistance value is larger than a preset threshold value, judging that the connection between the circuit board and the display screen is abnormal;
and if the resistance value is smaller than or equal to a preset threshold value, judging that the connection between the circuit board and the display screen is normal.
Specifically, the resistance value may be greater than a preset threshold value, less than the preset threshold value, or equal to the preset threshold value. When the resistance value can be larger than a preset threshold value, the circuit board and the display screen can be judged to be abnormal in connection; when the resistance value is smaller than a preset threshold value or equal to the preset threshold value, the circuit board can be judged to be normally connected with the display screen.
For example, the calculated resistance value may be 10 Ω, 8 Ω, or 5 Ω, and the preset threshold may be 8 Ω. If the resistance value is 10 omega, the resistance value is larger than a preset threshold value, and the circuit board and the display screen can be judged to be abnormal in connection; if the resistance value is 8 omega, the resistance value is equal to a preset threshold value, and the circuit board can be judged to be normally connected with the display screen; if the resistance value is 5 Ω, the resistance value is smaller than the preset threshold value, and the circuit board and the display screen can be judged to be normally connected.
Specifically, when the resistance value is greater than the preset threshold value, it can be determined that the connection between the circuit board and the display screen is abnormal. For example, the calculated resistance value may be 10 Ω, the preset threshold may be 8 Ω, and if the resistance value is greater than the preset threshold, it may be determined that the connection between the circuit board and the display screen is abnormal.
When the abnormal connection between the display screen and the circuit board is detected, the terminal can send out a related prompt message, so that after the step of determining that the abnormal connection between the circuit board and the display screen exists, the method further comprises the following steps of:
displaying an information prompt interface on the display screen, wherein the information prompt interface comprises a selection control for judging whether to continuously display a picture;
and when the touch operation of the user for the selection control is detected, judging whether the connection between the circuit board and the display screen is disconnected according to the touch operation.
Specifically, the information prompt interface is displayed on the display screen, and the information prompt interface may be a pop-up interface for the current display screen display interface. The pop-up interface may include a prompt message, for example, the prompt message may be "display screen connection is abnormal, and whether to continue displaying". The pop-up box interface can also comprise a selection control, and the selection control can be a prompt message of the user aiming at the pop-up box and executing different operations. For example, according to the prompting message content "whether to continue displaying", various selection controls can be included, and the selection controls can be "yes", "no", and the like.
For example, when the display screen displays the information prompt interface, if the user wants the display screen to continue displaying the image content, the user can click a selection control-yes of the information prompt interface; if the user wants to disconnect the display screen from the circuit board, the user can click a selection control-NO of the information prompt interface. The display box reminds a user of abnormal connection of the display screen through the display bullet frame, so that the user can know the abnormal problem of the display screen in time.
In this embodiment, when it is detected that the circuit board is electrically connected to the display screen, the input current and the input voltage of the display screen are obtained; determining an output voltage of the circuit board according to the input current; determining a resistance value between the output port and the input port when the circuit board is electrically connected with the display screen according to the input current, the input voltage and the output voltage; comparing the resistance value with a preset threshold value to obtain a comparison result; and judging whether the connection between the circuit board and the display screen is abnormal or not according to the comparison result. According to the scheme, the corresponding resistance value is calculated by obtaining the current and the voltage when the display screen is electrically connected with the circuit board, the abnormal connection between the display screen and the circuit board is judged according to the resistance value, the display screen can be prevented from being used under the heating condition, the service life of the display screen is prolonged, and the service efficiency of the terminal display screen can be effectively improved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a second display screen connection detection method according to an embodiment of the present disclosure. In this embodiment, the specific scene application of the display screen connection detection method may be as follows:
201. and the terminal receives a starting instruction triggered by a user and electrically connects the circuit board with the display screen according to the starting instruction.
In this embodiment, the terminal receives a start instruction triggered by a user, and the user may trigger the start instruction in various ways, for example, the user may turn on a terminal power switch, perform a touch operation on a terminal screen, or click a terminal screen button, and the like.
After the terminal receives a starting instruction triggered by a user, a battery in the terminal starts to work, the circuit board is electrically connected with the display screen, and power is supplied to the display screen to enable the display screen to start displaying image pictures. Referring to fig. 3, fig. 3 is a schematic diagram of a hardware connection of a display screen connection detection method according to an embodiment of the present disclosure. The circuit board may include an output port a, the display screen may include an input port B, and the output port a is electrically connected to the input port B.
202. The terminal obtains the input current and the input voltage of the input port of the display screen.
After the circuit board inside the terminal is electrically connected to the display screen, the display screen of the terminal may start to display an image, see fig. 4, where fig. 4 is a display interface diagram of a display screen connection detection method provided in the embodiment of the present application. The interface shown in fig. 4 may be a terminal lock screen interface.
Specifically, the terminal obtains an input current and an input voltage of the input port B of the display screen. Wherein the input current may be denoted by I, e.g. the input current I may be 1A. The input voltage may be represented by U1, for example, the input voltage U1 may be 10V.
203. And the terminal determines the connection resistance value of the output port of the circuit board and the input port of the display screen according to the input current and the input voltage.
In this embodiment, the terminal circuit board stores a current-voltage relationship table in advance, and the relationship table may include a circuit board output voltage corresponding to the input current I, where the output voltage may be represented by U2. Specifically, the corresponding relationship between the input current I and the output voltage U2 can be obtained through experiments. For example, in the corresponding relationship in the relational library, when the input current I is 1A, the output voltage U2 may be 5V; when the input current is 2A, the output voltage U2 may be 10V, and so on.
After determining the input current I, the input voltage U1, and the output voltage U2, the calculation may be performed according to a preset calculation rule, where the preset calculation rule may be R1 ═ I1 (U2-U1). R1 may be expressed as a resistance value between the output port a and the input port B. For example, if the input current I may be 1A, the input voltage U1 may be 4V, and the output voltage U2 may be 5V, then the resistance value R1 may be calculated to be 1 Ω according to the calculation formula.
204. And the terminal calculates the resistance value and a preset resistance value to obtain a resistance difference value.
Specifically, the preset resistance value may be a resistance value between the output port a and the input port B when the circuit board is normally connected to the display screen, and the preset resistance value may be represented by R2. For example, the resistance R1 may be 1 Ω, the predetermined resistance R2 may be 0.5 Ω, and the difference between the resistance R1 and the predetermined resistance R2 is 0.5 Ω.
205. The terminal judges whether the connection between the circuit board and the display screen is abnormal or not according to the comparison between the resistance difference value and the preset difference value, and if the connection between the circuit board and the display screen is abnormal, the step 206 is executed; if there is no exception, go to step 207.
Specifically, the preset difference may be obtained in the test detection according to the actual terminal, for example, the preset difference may be 5% of the preset resistance value R2.
For example, the resistance difference may be 0.5 Ω, and the preset difference is according to the formula: the 5% preset resistance value R2 can be found to be 0.025, and comparing the resistance difference value with the preset difference value can determine that the resistance difference value is greater than the preset resistance difference value. When the resistance difference is greater than the preset resistance difference, it is determined that the connection between the circuit board and the display screen is abnormal, and step 206 may be executed.
In some embodiments, if the resistance difference is smaller than or equal to the predetermined resistance difference according to the calculation result, it may be determined that the connection between the circuit board and the display screen is normal, and step 207 may be executed.
206. And displaying a prompt message on a terminal display screen.
Specifically, after it is determined that the connection between the circuit board and the display screen is abnormal, the terminal may pop up an information prompt pop-up frame on the display interface of the current display screen, referring to fig. 5, where fig. 5 is a prompt message interface diagram of the display screen connection detection method provided in the embodiment of the present application. The display interface shown in fig. 5 may include prompt text information, and the prompt text information may be "whether the display screen displays an abnormal state, and continues to display the screen! ", may include the selection controls" yes "and" no ".
For example, when the circuit board is abnormally connected with the display screen, the display screen pops up a prompt pop-up frame to prompt a user that the display screen is abnormally displayed, the user can click a selection control according to the content of the pop-up frame to execute the next operation, and if the user clicks 'yes', the terminal continues to display the current image picture; if the user selects 'no', the terminal closes the display screen to display the picture, and the electric connection between the circuit board and the display screen is disconnected.
207. And finishing the operation.
And the circuit board in the terminal is normally connected with the display screen, no operation is performed, and the display screen continues to display the current image picture.
In this embodiment, a terminal obtains an input current and an input voltage of an input port of a display screen, determines a connection resistance value between an output port of a circuit board and the input port of the display screen according to the input current and the input voltage, calculates the resistance value and a preset resistance value to obtain a resistance difference value, judges whether the connection between the circuit board and the display screen is abnormal or not according to comparison between the resistance difference value and the preset difference value, and displays a prompt message on the display screen of the terminal if the connection between the circuit board and the display screen is abnormal; if there is no exception, the operation ends. According to the scheme, the corresponding resistance value is calculated by obtaining the current and the voltage when the display screen is electrically connected with the circuit board, the abnormal connection between the display screen and the circuit board is judged according to the resistance value, the display screen can be prevented from being used under the heating condition, the service life of the display screen is prolonged, and the service efficiency of the terminal display screen can be effectively improved.
