[0003] At present, in existing elevators, one-way perspective glass mirrors are often used instead of ordinary glass mirrors, and a liquid crystal screen is placed behind the glass. When the screen is on, the video content on the screen can be seen in the car. When the screen is off, only the normal glass mirror can be seen in the car, and the screen behind the mirror is invisible. However, in winter, the temperature in the elevator is higher than the outside temperature, and the water vapor is heavy. It is easy to generate water vapor on the display screen, which will form a large number of water droplets, resulting in unclear display screens, affecting the visual effect of users, and reducing user experience. In addition, the display screen will generate a lot of heat during long-term operation. If the heat cannot be dissipated in time, it will cause the display screen to short-circuit or burn, posing a safety hazard. Utility Model Content
