Wireless screen projection method and LED display

Abstract

The embodiment of the invention relates to a wireless screen projection method and an LED display suitable for the wireless screen projection method. The wireless screen projection method comprises the following steps: receiving screen projection picture data transmitted by a screen projector in a wireless manner, wherein the screen projection picture data is video data obtained by accessing a preset storage space of the screen projector with a plug-and-play interface by source equipment and operating a target application program in the preset storage space to perform screen capture operation;acquiring image data acquired by a camera; performing face recognition detection on the image data to obtain a target face recognition detection result; and in response to the target face recognitiondetection result, decoding the screen projection picture data to obtain decoded data, and driving and controlling a target display screen to display a screen projection picture based on the decoded data. According to the embodiment, projection screen image display is triggered through a face recognition detection means, and the screen projector does not need to be provided with a physical key, sothat the service life of the screen projector can be prolonged.

Description

technical field [0001] The invention relates to the technical field of data transmission and display, in particular to a wireless screen projection method and an LED display. Background technique [0002] In related technologies, displaying content on one screen to another screen is called screen projection. Screen projection technology is widely used in work conferences, video education, home theaters, and other occasions. Based on screen projection technology, the media data played and displayed in the source device can be transmitted to the display screen of the display device for synchronous playback and display; the source device refers to the device that projects the media data to the display device for synchronous playback and display, such as a desktop Desktop computer, notebook computer, mobile terminal, etc. At present, screen projection technology is divided into wired screen projection technology and wireless screen projection technology. Among them, wireless sc...

AI Technical Summary

Problems solved by technology

[0003] The current wireless screen projection technology is mainly through the wired connection of the wireless screen projector and the source device, and by the user performing a corresponding mechanical trigger operation on the screen projector, the media data in the source device is wirelessly projected through the wireless screen projector. The screen is on a display device such as an LED conference screen; although it can realize screen projection, it requires additional pressing of the physical buttons on the wireless screen projector to trigger the screen projection operation, which is laborious and the physical buttons are prone to failure after multiple pressing operations
