  4. 4. The display device of claim 1, wherein the second controller is configured to: When the first controller opens a camera related application program when no application occupies the camera currently, a mark bit sys.camera.nova_used=0 is written on the second controller in a dual-system communication mode so as to mark that the first controller currently uses a camera node Video0; When the camera is not used at the first controller, the flag bit sys.camera. Nova_used= -1 is reset at the second controller to flag that the first controller is not using any camera nodes.
  5. 5. A method for sharing data transmitted by a camera, which is applied to a display device, wherein the display device comprises a camera, a display, a first controller and a second controller, the camera is connected with the second controller, and the first controller is connected with the display, the method comprises the following steps: When detecting that a user starts a camera related application program stored on the first controller, writing a mark bit on the second controller, and marking the running state of the camera; When the fact that a user starts a camera related application program stored on the first controller is detected, a first output node is virtualized out of the second controller, so that data collected from a camera are transmitted to the first controller through the first output node and a USB bus; and independent operating systems are respectively installed in the first controller and the second controller.
  6. 6. The method of claim 5, wherein the step of writing a flag bit on the second controller when the user is detected to launch a camera-related application stored on the first controller, and the step of marking the operational status of the camera comprises: When the first controller opens a camera related application program when no application occupies the camera currently, a mark bit sys.camera.nova_used=0 is written on the second controller in a dual-system communication mode so as to mark that the first controller currently uses a camera node Video0; When the camera is not used at the first controller, the flag bit sys.camera. Nova_used= -1 is reset at the second controller to flag that the first controller is not using any camera nodes.
  7. 7. A computer storage medium having stored thereon computer executable instructions for causing the computer to perform the method of any one of claims 5 to 6.

Description

Display equipment Technical Field The embodiment of the application relates to a display technology. And more particularly to a dual chip display device having a camera. Background Currently, a display device is receiving a great deal of attention from users because it can provide a user with a play screen such as audio, video, pictures, etc. With the development of big data and artificial intelligence, the functional demands of users on display devices are increasing. For example, the user wants to play the display screen and simultaneously present the multi-channel video chat screen, or the user displays the real screen of the participant in real time in the game scene, or the user learns the content of the current screen and performs remote audio/video interaction with parents/teachers in the education application program. However, current display devices, especially household devices such as smart televisions, cannot implement the above-mentioned scenario by themselves without a built-in camera. Therefore, there is an urgent need for a display device capable of presenting a conventional television picture and simultaneously presenting multiple video calls, so as to provide a user with a good user experience.
