An all-in-one computer with screen projection function and screen projection control method

Abstract

The invention discloses an all-in-one machine with a screen projection function and a screen projection control method. A communication transmission unit is used to establish a communication connection with an operating terminal; a temporary plank road storage unit is used to receive multiple screen projection data at the same time. Each temporary plank only receives one projection data at a time and distributes all the projection data to different temporary planks in sequence; the data identification unit is used to identify the data transmission on-off and data type of the projection data in each temporary plank The display split screen control unit automatically controls the number of split screens according to the identification results of the projection data in all temporary plank roads by the data recognition unit, and creates a tree-like selection activity correspondence between the projection data and the display split screen; the display size control unit is used for Adjust the size of each screen of the split screen of the display; the present invention realizes that the replacement of the projected screen content affects the normal operation of the projected screen, and avoids the accidental release of content that does not need to be projected to ensure the stability of the projected screen.

Description

technical field [0001] The invention relates to the technical field of screen projection all-in-one machines, in particular to an all-in-one machine with a screen projection function and a screen projection control method. Background technique [0002] The function of same-screen interaction allows users to project all content on the screens of Windows laptops, Android smartphones / iPhone / tablets and other devices to touch all-in-one computers that support this function to achieve multi-screen sharing. [0003] Generally, if a mobile phone needs to cast its screen to a smart TV, the mobile phone and the smart TV must first be in the same L2 LAN. Secondly, both mobile phones and smart TVs are required to support screen projection protocols such as AirPlay, Miracast, and DLNA, which are generally supported by modern mobile phones and smart TVs. APP, can also realize the screen projection operation. [0004] Although the existing screen projection methods are various, the disa...

Problems solved by technology

[0007] The purpose of the present invention is to provide an all-in-one machine with a screen projection function and a screen projection control method to solve the problem that in the prior art, when the operation terminal opens other content that does not need screen projection, the display of the all-in-one machine will operate other operation content of the terminal The position of synchronous display and projection data is relatively fixed, and it is not convenient to change the technical problem of display position
