Abstract

The embodiment of the invention provides a screen projection control method, a screen projector and a processing chip. The method is applied to the processing chip in the screen projector, the screen projector further comprises a touch screen and a touch circuit board, and the processing chip is electrically connected with the touch circuit board and a light emitting device. The method comprises the following steps: acquiring a first touch signal generated by a touch circuit board, wherein the first touch signal is generated by the touch circuit board when a first touch operation exists on a touch screen; controlling a light-emitting device to display a first screen projection lamp effect based on the first touch signal, and starting a screen projection function. A user can start the screen projection function of the screen projector by carrying out the first touch operation on the touch screen, and the problem that a button is stuck does not occur. The screen projector can display the first screen projection lamp effect to prompt a user of the current state of the screen projector, and the man-machine interaction effect is good.

Description

technical field [0001] The present application relates to the technical field of screen projection, and in particular to a screen projection control method, a screen projection device and a processing chip. Background technique [0002] The content in one device can be projected to another device for display by using the screen projector, for example, the content in a laptop can be projected to a tablet computer with a large screen for display, etc. The screencaster acts as a bridge between the two devices. [0003] Current screen projectors are generally button-type screen projectors, and users can press mechanical buttons to control the screen projector to turn on or off the screen projection function. Since the mechanical button is prone to a seesaw phenomenon when pressed, the button is easy to get stuck, and the above-mentioned screen projection device has poor human-computer interaction when in use. Contents of the invention [0004] The purpose of the embodiment o...
