The invention discloses an emitter and a wireless screen projection device. According to one specific embodiment, the transmitter comprises a first input device, a first controller and a wireless transmission module for realizing wireless connection with a receiver, the first controller is used for sending a screen image from a first terminal device connected with the emitter to the receiver through the wireless transmission module, so that the receiver transmits the screen image to a display device connected with the receiver for display; and the first controller is also used for responding to the operation of the user on the first input device, so that the display device stops displaying the screen image. According to the embodiment, rapid screen locking can be conveniently realized by utilizing the emitter, and the embodiment is high in compatibility and can be applied to various types of terminal equipment for wireless screen projection.
Description
technical field [0001] The invention relates to the technical field of wireless screen projection. More specifically, it relates to a transmitter and a wireless screen projection device. Background technique [0002] At present, wireless screen projection devices are widely used in various fields. Taking the wireless screen projection office field as an example, in conference scenes, speakers often use wireless screen projection devices to display the screen images of terminal equipment such as laptops in large sizes. Displayed on the screen or projected through a projector, the business reports, analysis data and other information in the PPT slides shown on the laptop can be displayed to the participants through a large-size display or projector. [0003] Existing wireless screen projection devices include a transmitter and a receiver, and the transmitter and receiver are wirelessly connected, usually WiFi; A wireless transmission module (such as a Wifi module) for realiz...
