Method and device for controlling roller shutter

Abstract

The invention discloses a method for controlling a roller shutter for a display screen. The method comprises the following steps: a receiving module receives an open signal or close signal of the display screen; when the receiving module receives the open signal, a control module sends a roller shutter rolling-up instruction; when the receiving module receives the close signal, the control module sends a roller shutter spreading instruction; an electric roller shutter rolls up the roller shutter according to the roller shutter rolling-up instruction sent by the control module so as to expose the display screen; or the electric roller shutter spreads the roller shutter according to the spreading instruction sent by the control module so as to cover the display screen. The invention also correspondingly discloses a device for controlling the roller shutter for the display screen and a television using the same. By adopting the technology disclosed by the invention, automatic and intelligent dustproof functions of the roller shutter can be realized.

Description

technical field [0001] It relates to roller blind technology, in particular to a method and device for controlling a roller blind. Background technique [0002] Television sets have become a necessity in people's lives. Generally speaking, for the convenience of life, TV sets, especially their display screens, are exposed to the air, which makes the TV sets or display devices vulnerable to dust, external electronics, etc. The damage of radiation, etc., thus affecting its lifespan. [0003] Some solutions have appeared in the prior art, for example, one is that the user himself puts coverings such as a cloth cover on the TV set; After watching TV, go forward and dial the button or dial on the electric or manual roller blind to unfold the roller blind to cover the TV or the TV display screen; when you need to watch TV, you also need to go forward and manually operate the button or the dial to retract the roller blind to expose the TV display. [0004] The first solution is ...

AI Technical Summary

Problems solved by technology

[0004] The first solution is obviously very troublesome, so many users are too lazy to cover it every time, so it can't actually achieve the purpose of dustproof and so on.

[0005] One of the implementations of the second solution is as figure 1 As shown, the second solution is improved compared to the first solution, but the user needs to go to the TV 01 to roll up or unfold the roller blind 02 before watching TV or after watching TV, which is still troublesome

[0006] How to solve the problem of inconvenient control and insufficient automation of roller blinds, this is exactly where the existing technology needs to be improved
