Description

Display device and operation method for the same Technical Field The present invention relates to an electronic device and an operating method for the electronic device, and more particularly, to a display device and an operating method for the display device. Background With the development of display device technology, more use scenes are provided, and the multi-screen connection of a plurality of display devices can bring wide viewing angles, better immersion sense and multi-window display and processing. The multi-screen connection of multiple display devices has become a necessary requirement for multi-service operation in the office, game, and movie industries. However, the appearance of the USB Type-C sized connection ports of the display device are the same. It is difficult for the user to recognize the USB Type-C sized connection port of the display device. Therefore, the probability of connection error is increased. In the case of a connection error, the display device can display only abnormal pictures such as blue screen and black screen. The user can only find out or try different connection modes until the display device is connected with the video source device (such as the display device for providing video signals) correctly and normally. Therefore, the connection between the display device and the video source device reduces the experience of the user. Therefore, how to provide a display system capable of detecting the connection state of the display device and providing the connection prompt screen according to the connection state is one of the important points of the study of the person skilled in the art. Accordingly, there is a need to provide a display device and an operating method for the display device to solve the above-described problems. Disclosure of Invention The invention provides a display device and an operation method for the display device, which can detect the connection state of the display device and provide a connection prompt screen according to the connection state.

The detection circuit is coupled to the input port and the output port. The detection circuit generates a first state value according to the connection state of the input port and generates a second state value according to the connection state of the output port. The processor is coupled to the data port and the detection circuit. The processor generates a third state value according to the connection state of the data port. The processor reads the first state value and the second state value, and judges the connection between the display device and the video source and provides a connection prompt signal according to the first state value, the second state value and the third state value. The connection prompting circuit is coupled to the processor. The connection prompt circuit controls the display device to display a connection prompt picture in response to the connection prompt signal. The operation method of the invention is used for the display device. The display device includes an input port, an output port, a data port, and a detection circuit. The operation method comprises the steps of generating a first state value by a detection circuit according to the connection state of an input port, generating a second state value by the connection state of an output port, judging the connection between a display device and an audio-visual source according to the first state value, the second state value and a third state value corresponding to the connection state of a data port, providing a connection prompt signal, and controlling the display device to display a connection prompt picture in response to the connection prompt signal. Based on the above, the display device confirms the connection result of the display device and the video source according to the first state value, the second state value and the third state value, and displays the connection prompt screen accordingly. In this way, in the case of a connection error, the display device can provide a connection prompt screen to guide the user to perform a correct connection.
