Preferably, the top shading sheet is provided with a skylight opening, a skylight cover is arranged at the skylight opening, the skylight cover is adhered to the top shading sheet through a single-sided nano adhesive tape, and the rotatable polarization adjusting ring of the camera is conveniently adjusted through the skylight cover.

Preferably, the arc-shaped polaroid is formed by laminating a linear polarization module and a transparent PC film.

The invention has the beneficial effects that: the invention makes the light from the surrounding environment and the reflection of other objects on the glass only pass through the polaroid at a certain specific angle and reflect on the glass display panel with the camera through the arc polaroid, and filters out the reflected light of the surrounding environment and the objects on the glass and enters the camera after the rotation of the rotatable polarized light adjusting ring assembled in front of the camera is adjusted to a certain angle, so that the camera only acquires the images of users and handwriting needed by people, the acquired images are very clean, and the use effect of the glass display panel with the camera is improved; the supporting component and the polarizer component are connected through magnetic attachment of the rubber magnetic strip, so that the supporting component and the polarizer component are convenient to disassemble and assemble; support frame and arc strip both ends are rotated through rotatory pivot through last horizontal pole both ends and are connected through riveting post and preceding support frame both sides bottom rotation before connecting, make it on the arc strip and the arc strip can rotate the level when using with down and expand the state, can rotate when not using with preceding support frame laminating state, be convenient for accomodate.
