And the different specifications of the port 13, the wireless communication module 14 for wireless networking and the storage space for storing some necessary programs or other materials, the port 13 can be mainly divided into a USB port or an RJ45 port, a USB connection.埠 used to connect external discs such as USB storage devices or external hard drives, and the RJ45 port is connected to the network information through physical lines. In addition to the display 1 has the ability to access the Internet, the display 1 can also be used by the network. The disk drive obtains the required information, and the wireless communication module 14 provides the function of wirelessly connecting the network, or performs the necessary information connection through wireless communication, such as the function of communicating with a personal computer or a smart phone. The data of the disc or the external disc can be stored in the storage space 15 for subsequent use.

In addition to the above-mentioned basic part, the display 1 has a main hardware part that realizes the source of the detection signal and switches by itself, such as the path setting unit 2, the signal source checking unit 3, the operation judgment checking unit 4, the checking time setting unit 5, and The background service check unit 6, the main purpose of the present invention is that the signal source switches by itself. When no external signal is input or operated, the information in the storage space 15, the external disk or the network disk is played, and the path is The setting unit 2 mainly sets the information to be played when there is no external information input, and the signal source checking unit 3 is used to check whether there is an external signal input. The operation determining and checking unit 4 is used to check whether there is an operation command input or not. The time setting unit 5 provides a time setting. When there is no external signal input or operation, after a certain time, it will switch to the storage space and the like to play the memory information, and the time parameter is completed by this, and the background service checking unit 6 is When the display 1 starts playing information such as storage space, check whether the external signal is restored or not. In particular, the display 1 of the present invention mainly works on external signal playback. When there is no external signal or operation, it will enter the sub-program for playing the information in the storage space by itself. In the process of executing the secondary program, The current status will be checked continuously and the subroutine will be interrupted if an external signal or operational action occurs.

Please refer to FIG. 2 , which is a schematic flowchart of the steps of the method for self-switching according to an embodiment of the display of the present invention. Steps S1 to S4 can be seen from the figure, which are described as follows:

In step S1, in the state where the external signal information is input and played, this is the part of the first check.

In step S2, in the state where the external signal information is interrupted, this is the part of the second check.

Step S3 is in the first background service check at this time, and occurs in the state that there is no external input signal and no operation behavior, and it will check again whether there is an external signal input, operation or event in a certain time, which is the third The part of the inspection, when passed the inspection, will enter the sub-program, that is, play the information in the storage space.

Step S4 is in the second background service check, and occurs in the state of playing the information in the storage space, and will repeatedly check whether there is an external signal input, operation or event, which is the fourth part of the inspection. When the check fails, it will leave the subroutine and return to the main program to play the external signal or respond to the current operation.

Step S3 is composed of S31~S35, and the description is as follows:

In step S31, in order to start the background service check, the subsequent check will loop back to this action.

In step S32, in order to start the background service check, the second step is to check whether there is an external signal input, and if yes, jump back to play the external signal action, if not, perform the next check.

Step S33, in order to start the third step of the background service check, check whether there is an operation or an event, if yes, jump back to play the external signal action, if not, proceed to the next check.

Step S34, in order to start the background service check, the entire background service check is completed, and according to the result, the process returns to S31 or enters the sub-program (playing information in the storage space).

In step S35, this is an additional action, mainly setting the length of the entire inspection time of S31~S34, and when the time is over, it will enter the subroutine to play.

Among them, step S4 is composed of S41~S44, and the description is as follows:

In step S41, in order to start the background service check, the subsequent check will loop back to this action.

Step S42, in order to start the second step of the background service check, check whether there is an external signal input, if any, stop playing the information in the storage space and jump back to play the external signal action, if not, perform the next check.

Step S43, in order to start the third step of the background service check, check whether there is an operation or an event, if any, stop playing the information in the storage space and jump back to the playing action, if not, perform the next check.

Step S44, in order to start the background service check, the entire background service check is completed, and the result returns to S41 or enters the main program (plays an external signal).

Please refer to FIG. 3 , which is a schematic flowchart of a method for determining a self-switching method according to an embodiment of the present invention. The figure is an actual program judgment flow chart, which is described as follows:

The S51 television plays an external signal; for normal working conditions, the display plays an external signal, and proceeds to step S52.

The S52 TV loses the external signal; for the first inspection item, it is judged whether there is an external signal, if yes, it enters S53, otherwise it enters S51.

S53 has no internal or external key events or operations; for the second inspection item, it is determined whether there are internal or external key events or operations, which can be recognized as operations or reminders, if yes, then proceeds to S54, otherwise to S51.

The S54 background service check is started; the check loop for preparing to enter the information in the playback storage space is looped, and the flow proceeds to step S55.

The S55 TV loses the external signal; for the first check item in the loop, it is judged whether there is an external signal, if yes, it enters S56, otherwise it enters S51.

S56 has no internal or external key events or operations; for the second check item in the loop, it is judged whether there are internal or external key events or operations, which can be recognized as operations or reminders. If yes, enter S57. Otherwise enter S51.

The S57 background service checks the timeout mechanism; for the third check item in the loop, it is ready to enter the check and judgement of the information in the playback storage space. Because the external signal is often unstable, it is used as a mechanism for detecting whether the signal service times out. To determine whether there is no external signal, if yes, go to step S58, if otherwise, go to step S54.

The S58 starts to play the information in the storage space; that is, when the display enters the idle mode, the information in the storage space is usually a plurality of pictures or short films, and a dynamic photo wall or a looping movie is performed to improve the overall use effect, and the process proceeds to step S59. .

The S59 background service check starts; at this time, the information in the storage space is played, and the polling loop is performed, and the process proceeds to step S60.

The S60 TV loses the external signal; it polls the first check item in the loop to determine whether there is still no external signal. If yes, it enters S61, otherwise it enters S63.

S61 has no internal or external key events or operations; for polling the second check item in the loop, it is determined whether there are internal or external key events or operations, which can be recognized as an operation or reminder, if yes, then enter S62, If not, enter S63.

The S62 background service check ends; in order to prepare to enter the check loop for playing the external information, if the polling loop (S59~S62) is not satisfied, the process proceeds to step S63, and then proceeds to step S51, and if it is satisfied, the polling is repeated. Circle (second jump back to S59).

S63 stops playing the information in the storage space; if there is any non-conformity in the check condition occurring in the polling loop, it can be regarded as any condition to interrupt the idle state of the display, and proceeds to step S51.

It can be seen that such a method and structure can make the display 1 have better use in an idle state, and can also be regarded as adding new functions, which is convenient for use and added value, and the above mentioned dynamics. The photo wall interval, the effect of playing the movie, checking the no signal time, etc., are all available for the user to adjust.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention.
