The invention discloses a transmitter and a wireless screen projection device. A specific embodiment of the transmitter includes a first input device, a first controller and a wireless transmission module for wireless connection with the receiver; The screen image of the device is sent to the receiver through the wireless transmission module, so that the receiver transmits the screen image to a display device connected to the receiver for display; the first controller also uses In response to a user's operation on the first input device, the display device stops displaying the screen image. This implementation manner can use a transmitter to conveniently realize fast screen locking, and this implementation manner has high compatibility, and can be applied to various types of terminal devices that perform wireless screen projection.
Description
technical field [0001] The present 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 field of wireless screen projection in the office as an example, in conference scenarios, speakers often use the wireless screen projection device to display the screen image of a terminal device such as a notebook computer through a large-scale display. It can be displayed on the screen or projected through a projector, so that 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 screen or a projector. [0003] The existing wireless screen projection device includes a transmitter and a receiver. The transmitter and the receiver are connected wirelessly, ...
