Description

Signal state display method and display equipment

Technical Field

The present application relates to the field of display technologies, and in particular, to a signal state display method and a display device.

Background

Currently, a display device may be connected to an external device through various signal source interfaces. When the display device detects the connection state of the external device or the signal state update of the external device, the corresponding prompt message is usually displayed.

For example, when it is detected that the external device is connected to a Signal source interface, the display device may update the connection state, and display the prompt information with "Signal connected" (Signal connected); for another example, when it is detected that the Signal state of the external device connected to a certain Signal source interface is updated from absence of a valid Signal to presence of a valid Signal, the display device may display a prompt message with "received Signal" content corresponding to the Signal state update; for another example, when it is detected that the Signal status of the external device connected to a certain Signal source interface is updated from the presence of a valid Signal to the absence of a valid Signal, the display device may display a prompt message with "Signal lost" content corresponding to the Signal status update.

However, in some cases, for example, when an external device connected to the display device is powered on from a standby state, a signal input to the display device by the external device needs a certain time to be locked, and during this time, the signal state of the external device frequently changes between the presence of a valid signal and the absence of a valid signal, which results in frequent display of prompt information updated by the display device corresponding to each signal state of the external device, and affects user experience.

a signal detection module, configured to detect a signal state of an external device accessing the display device according to a preset time period, where when it is detected that the signal state of the external device is switched from a first state to a second state, the first state indicates that no valid signal exists, the second state indicates that a valid signal exists, and starts to record the signal state of the external device detected each time, and when a number of consecutive times that the recorded signal state of the external device is the second state reaches a number threshold, report the signal state of the external device to the UI module as the second state;

and the UI module is used for displaying prompt information corresponding to the second state through the display when the signal state of the external equipment reported by the signal detection module is the second state.

In a second aspect, a signal status display method is provided, which is applied to a display device, where the display device at least includes a signal detection module and a user interface UI module, and includes:

the signal detection module detects the signal state of the external device accessed to the display device according to a preset time period, when the signal state of the external device is detected to be switched from a first state to a second state, the first state indicates that no effective signal exists, the second state indicates that an effective signal exists, the signal state of the external device detected each time is recorded, and when the recorded continuous times that the signal state of the external device is in the second state reach a time threshold value, the signal state of the external device is reported to the UI module to be in the second state;

and when the signal state of the external equipment reported by the signal detection module is a second state, the UI module controls the display equipment to display prompt information corresponding to the second state.

In the above embodiment, when the signal state of the external device is continuously detected for multiple times as the second state, the display device may display, on the display, the prompt information corresponding to the second state through the UI module. Therefore, the problem that the display equipment frequently displays prompt information according to frequent change of the signal state in the signal locking process of the external equipment input display equipment can be effectively avoided.

In one embodiment, the signal state display method may include: when the signal state of the external equipment accessed to the display equipment is determined to be switched from the absence of the effective signal to the presence of the effective signal, whether the signal state of the external equipment is stable or not is further judged, and corresponding prompt information is displayed under the condition that the signal is determined to be stable.

In order to make those skilled in the art better understand the method provided by the embodiments of the present application, the following description is taken in conjunction with fig. 2.

Referring to fig. 2, fig. 2 is a flowchart illustrating a signal status display method provided by an embodiment of the present application. In one example, the method may be applied to a display device, such as a digital television, a smart television, or the like, which may include at least a signal detection module and a UI module. It should be noted that the signal detection module and the UI module are named for convenience of description, and other names may be used in practical applications. As shown in fig. 2, the process may include the following steps:

step S41, the signal detection module detects the signal status of the external device connected to the display device according to a preset time period, and starts to record the detected signal status of the external device each time when detecting that the signal status of the external device is switched from the first status to the second status.

The signal state here is a first state indicating that no valid signal is present and a second state indicating that a valid signal is present.

The first state and the second state are names for easy distinction and are not intended to limit the present application. For example, in practical applications, the first state may be a signal unlock state, and the second state may be a signal lock state.

In one example, the display device has various types of signal source interfaces for connecting external devices, such as a High Definition Multimedia Interface (HDMI), an Audio Video (AV) Interface, a Video Graphics Array (VGA) Interface, a Components Interface, and the like, and the external devices connected to the signal source interfaces can input signals to the display device as signal sources of the display device. As one embodiment, the display apparatus may determine a connection state of the external apparatus to each signal source interface by detecting a voltage value change of the signal source interface.

According to one embodiment, when the UI module of the display device detects that the external device is connected to any signal source interface, the UI module can display corresponding prompt information through the display. For example, a signal source icon corresponding to the signal source interface can be highlighted on the signal source interface; the first prompt box is used for prompting that the signal source interface has external equipment access; and so on.

As an embodiment, when detecting that an external device connected to any signal source interface is unplugged, the UI module of the display device may also display corresponding prompt information through the display. For example, a signal source icon corresponding to the signal source interface can be non-highlighted on the signal source interface; the second prompt box is used for prompting that the external equipment accessed to the signal source interface is disconnected; and so on.

In one example, for a signal source interface connected to an external device, the signal detection module may detect whether specified information exists in an input signal of the signal source interface, so as to determine whether the input signal of the signal source interface is a valid signal, that is, detect a signal state of the external device. As an embodiment, for any signal source interface accessing to the external device, it may be detected whether timing information exists in the signal input by the signal source interface, and if the timing information exists, it is determined that the signal input by the signal source interface is an effective signal, that is, it is determined that the signal state of the external device accessing to the signal source interface is the second state; otherwise, determining that the signal input by the signal source interface does not have a valid signal, that is, determining that the signal state of the external device connected to the signal source interface is the first state.

Timing information in the signal is used for reflecting the number of pixels of the video signal, and may generally include Hactive (horizontal display pixel point number) information, Htotal (horizontal actual pixel point number) information, Vactive (vertical display pixel point number) information, and Vtotal (vertical actual pixel point number) information.

When the signal detection module detects the signal state of the external device connected to the display device according to a preset time period, in one example, the time period may be preset according to the working experience of the worker, for example, may be set to 50 μ s. As an embodiment, different time periods may be set in advance for different types of signal source interfaces, that is, a corresponding relationship between the type of the signal source interface and the time period is set. When detecting the signal state of the external device, the signal detection module may search, according to the interface type of the signal source interface to which the external device is connected, a time period corresponding to the interface type in a pre-configured correspondence relationship between the signal source interface type and the time period, and detect the signal state of the external device according to the searched time period.

In one example, when the signal state of the external device is detected according to the preset time period, the signal detection module compares the signal state detected each time with the signal state detected last time, and if the signal states detected two times are different, the step S41 is selectively executed according to the specific signal state, or the UI module is executed to report the signal state detected this time to display the prompt information corresponding to the signal state.

As an example, when the signal state detected this time is the second state and the signal state detected last time is the first state, that is, when it is determined that the signal state is switched from the first state to the second state, the above step S41 is executed; and reporting the external equipment as the first state detected this time to the UI module when the signal state detected this time is the first state and the signal state detected last time is the second state, namely when the signal state is determined to be switched from the second state to the first state.

As an embodiment, in the case where the detected signal state of a certain external device is currently recorded, the detected signal state of the external device is not compared with the signal state detected last time for each time.

In one example, the signal detection module may record the detected signal status of the external device in a variety of ways.

As an embodiment, after starting recording of the signal state of the external device detected each time, when the signal state of the external device is detected, the signal state is recorded without overwriting the signal state recorded last time. For example, when the signal state of the external device is detected to be the first state for the first time, the first state is recorded, and when the signal state of the external device is detected to be the second state for the second time, the second state is recorded after the first state existing in the record, and the recording is described as: a first state and a second state.

As another embodiment, the signal status of the external device may also be recorded by counting the first status and the second status, respectively. Specifically, the count value of the first state may be incremented by 1 when the signal state of the external device is detected to be the first state, the count value of the second state may be incremented by 1 when the signal state of the external device is detected to be the second state, and the count value of the first state may be cleared if the signal state of the external device is detected to be the second state when the count value of the first state is not 0; when the signal state of the external device is detected to be the first state when the count value of the second state is not 0, the count value of the second state is cleared. Thereby, the number of times of continuously detecting the signal state of the external device as the first state/the second state can be effectively recorded.

As another example, since the method provided by the present application is implemented with an emphasis on determining whether the number of times that the signal status of the external device is continuously detected as the second status reaches the threshold number of times, only the detected second status may be counted. Specifically, when the signal state of the external device is detected as the second state, the count value of the second state is incremented by 1, and when the signal state of the external device is detected as the first state in a case where the count value of the second state is not 0, the count value of the second state is cleared. Therefore, the number of times that the signal state of the external device is continuously detected to be the second state can be effectively recorded.

Step S42, when the recorded number of consecutive times that the signal status of the external device is the second status reaches the threshold value, reporting the signal status of the external device as the second status to the UI module.

As an embodiment, the signal detection module may check whether the number of consecutive times that the currently recorded signal state of the external device is the second state reaches the number threshold each time the signal state of the external device is recorded.

In one example, the threshold number of times may be pre-configured based on the work experience of the worker. As an embodiment, different times threshold values may be configured in advance for different types of signal source interfaces, that is, a corresponding relationship between the type of the signal source interface and the times threshold value is configured. For example, for an HDMI interface, the configurable number threshold is 2; for a VGA interface, the configurable number threshold is 4.

As an embodiment, the signal detection module may search, according to an interface type of a signal source interface accessed by the external device, a number threshold corresponding to the interface type in a pre-configured correspondence relationship between the signal source interface type and the number threshold, and determine the found number threshold as the number threshold in step S42.

When the recorded continuous times that the signal state of the external device is in the second state reach the time threshold, the signal state of the external device is considered to be stable, or the locking is completed, so that the signal state of the external device is reported to the UI module as the second state, and the UI module can display corresponding prompt information according to the stable second state.

To facilitate understanding that the signal state is the second state, the number of consecutive times reaches the number threshold, a simple example is as follows:

taking the number threshold as 4 times as an example, if the currently recorded signal states of the external device are respectively: the first state, the second state, and the second state, it can be seen that the signal states of the external device detected for the last 4 times recorded currently are all the second states, that is, the number of consecutive times that the signal state is the second state reaches the number threshold 4 times.

In one example, the signal detection module may stop recording the detected signal state of the external device when the number of consecutive times that the recorded signal state of the external device is in the second state reaches a number threshold.

When the above steps S41 and S42 are implemented in detail, there are many possible implementations, which are described by way of example below and are not described herein again.

And step S43, when the signal state of the external device reported by the signal detection module is the second state, the UI module controls the display device to display the prompt message corresponding to the second state.

In an example, when the signal state of the external device reported by the signal detection module is received, the UI module may control the display device to display the corresponding prompt information according to the signal state. As an embodiment, when the signal state is the second state, the UI module may determine prompt information corresponding to the second state, and output the prompt information to a display of the display device, so that the prompt information is displayed by the display.

As an embodiment, the prompt information corresponding to the second state may include: highlighting a signal source icon corresponding to a signal source interface accessed by the external equipment at the signal source interface; displaying a third prompt box, wherein the third prompt box is used for prompting that an external device accessed to the signal source interface currently has an effective signal, and the third prompt box can also be used for prompting that the display device can be switched from the current signal source channel to the signal source channel corresponding to the signal source interface by pressing a designated key on the control device; and so on.

As an embodiment, a display duration may be set when the first, second, and third prompt boxes are displayed, and the prompt boxes may be hidden when the display duration is reached. Specifically, the first, second, and third prompt boxes may be toast message prompt boxes.

It is easily understood by those skilled in the art that, when the signal state of the external device reported by the signal detection module is the first state, the UI module may also display a prompt message corresponding to the first state through the display, which is not described in detail herein.

Thus, the flow shown in fig. 2 is completed.

Through the process shown in fig. 2, when the number of times of continuously detecting that the signal status of the external device is the second status (there is a valid signal) reaches the number threshold, the display device may display the prompt information corresponding to the signal status.

As an embodiment, the signal detection module may include a detection submodule and a determination submodule, where the detection submodule is configured to detect a signal state of an external device accessing the display device according to a preset time period, and report the detected signal state to the determination submodule; the determining submodule is configured to report the signal state to the UI module according to the signal state reported by the detecting submodule, or further determine whether the number of consecutive times that the recorded signal state of the external device is the second state reaches a number threshold through the steps S41 and S42, and report the signal state of the external device to the UI module as the second state when the number threshold is determined to be reached.

Next, with reference to fig. 3, a specific implementation of steps S41 and S42 in the flow shown in fig. 2 is described as an example.

Referring to fig. 3, fig. 3 illustrates a flowchart of one implementation of steps S41, S42, which may be performed by the signal detection module. As shown in fig. 3, the process may include the following steps:

and step S51, when the signal state of any external device connected to the display device is detected to be switched from the first state to the second state, recording the external device to the signal source list.

In one example, the external device may be recorded to the signal source list by recording the signal source interface accessed by the external device. As an embodiment, when it is detected that the signal state of an external device accessing any signal source interface of the display device is switched from the first state to the second state, specifically, when it is detected that the signal state of an input signal of the signal source interface is switched from the first state to the second state, the signal source interface may be recorded in the signal source list.

For example, when the signal state of the external device connected to the HDMI interface is detected to be switched from the first state to the second state, the HDMI interface can be recorded in the signal source list; when the signal state of the external device connected to the VGA interface is switched from the first state to the second state, the VGA interface can be recorded in the signal source list.

In step S52, for each external device recorded in the signal source list, the signal status of the external device detected each time is recorded.

As an embodiment, when any external device is detected to be recorded in the signal source list, the start of recording the detected signal state of the external device may be triggered. Specifically, a recording thread may be started for the external device to record the signal state of the external device detected each time.

Step S53, when the continuous times that the recorded signal state of any external device is in the second state reaches the time threshold corresponding to the external device, reporting that the signal state of the external device is in the second state to the UI module, and stopping recording the signal state of the external device.

Here, the time threshold corresponding to the external device may be determined according to an interface type of a signal source interface to which the external device is accessed, which has been described above through the embodiments and is not described here again.

Through the present step S53, the signal status of the external device can be continuously recorded before the number of times that the signal status of the external device is continuously detected to be the second status reaches the number threshold corresponding to the external device, that is, before the signal input to the display device by the external device is stable.

In one example, when recording the signal status of any external device, if the detection result of each signal status is recorded, only the signal status detected in the last N times can be retained. Here, N, as an embodiment, may be determined according to a number threshold corresponding to the external device, for example, for an external device whose corresponding number threshold is 4, only the signal status detected for the last 4 times may be retained.

As an embodiment, after stopping recording the signal status of any external device, the external device may be removed from the signal source list. As an embodiment, after removing any external device from the signal source list, the signal source interface accessed by the external device may be recorded in an effective interface list, where the effective interface list is used to record the signal source interface currently accessed by the external device and having the input signal state of the second state.

As an embodiment, the signal detection module may stop recording the detected signal status of any external device when the recorded total number of times of detection of the signal status of the external device reaches a total number threshold, and restart recording the signal status of the external device each time the signal status of the external device is detected to be the second status. By the embodiment, unnecessary resource occupation caused by recording the signal state of the external equipment under the condition that the signal cannot be stabilized all the time due to some reasons such as external equipment faults can be avoided.

The flow shown in fig. 3 is completed.

Regarding the steps S41 and S42 in the flow shown in fig. 2, the present application also provides another specific implementation manner, which is described below with reference to fig. 4 by way of example.

Referring to fig. 4, another implementation flowchart of steps S41, S42 is exemplarily shown in fig. 4, and the flowchart can be applied to the signal detection module. As shown in fig. 4, the process may include:

and step S61, when the signal state of any external device connected to the display device is detected to be switched from the first state to the second state, recording the external device to the signal source list.

In step S62, for the target external device recorded in the signal source list, the signal state of the target external device detected each time is recorded.

The target external device in step S62 may be the external device that is currently recorded in the signal source list first.

Step S63, when the recorded continuous times that the signal state of the target external device is in the second state reaches the time threshold corresponding to the external device, reporting the signal state of the target external device to the UI module that the signal state is in the second state, stopping recording the signal state of the target external device, and removing the target external device from the signal source list; and when the recorded total detection times of the signal state of the target external device reach a total time threshold value, stopping recording the signal state of the target external device, and removing the target external device from the signal source list.

As an embodiment, after the target external device is removed from the signal source list, if there are external devices in the current signal source list, one of the external devices is taken as the target external device, and the steps S62 and S63 are executed.

As an example, the total number threshold in step S63 may be set according to the work experience of the worker, for example, 10 times.

The flow shown in fig. 4 is completed.

The flows shown in fig. 3 and 4 are examples. In practical applications, other solutions that can be obtained by those skilled in the art without creative efforts based on the flow shown in fig. 2, fig. 3, and fig. 4 should be considered to be within the protection scope of the present application.

As described in the above embodiments, the display device may display the corresponding prompt information on the display through the UI module when the signal status of the external device is continuously detected to be the second status for a plurality of times. Therefore, the problem that the display equipment frequently displays prompt information according to the change caused by frequent change of the signal state in the signal locking process of the external equipment input display equipment can be effectively avoided.
