Abstract
Provided are a display device and an operating method for the display device. The display device includes a display panel, a channel selection circuit, and a processor. The channel selection circuit transmits communication data through one of channels. The processor receives image data and controls the display panel to display an image according to the image data. The processor determines an image source of the image according to a link command. The processor switches one of the channels to be an active channel according to the image source.

A display device, comprising:
- a display panel;
- a hub circuit;
- a channel selection circuit coupled to the hub circuit, and configured to transmit communication data through one of a plurality of channels;
- and
- a processor coupled to the channel selection circuit and the display panel, and configured to:
- receive image data, and control the display panel to display an image according to the image data;
- determine an image source of the image data according to the link command in response to receiving a link command, wherein the link command is a communication signal that an electronic device does not detect the hub circuit;
- determine a result of whether the image source originates from the electronic device that provides the link command;
- and
- switch one of the channels to be an active channel according to the result.
An operating method adapted to a display device, wherein the display device comprises a processor, a display panel, and a channel selection circuit, and the operating method comprises:
- receiving, by the processor, image data, and controlling the display panel to display an image according to the image data;
- transmitting, by the channel selection circuit, communication data through one of a plurality of channels;
- in response to a link command, determining, by the processor, an image source of the currently displayed image according to the link command, wherein the link command is a communication signal that an electronic device does not detect the hub circuit;
- determining a result of whether the image source originates from the electronic device that provides the link command;
- and
- switching, by the processor according to the result, one of the channels to be an active channel.
