AI Technical Summary

Technical Problem

The projection screen in laser projection equipment is prone to wrinkles after being rolled up for a long time, which can cause image distortion and affect the display effect.

Method used

The design combines a rollable substrate with a rolling mechanism. The optical engine is located in the first accommodating part, and the rolling mechanism is located in the second accommodating part. The screen is bonded to the rollable substrate. The screen can be rolled up and down by retracting and unfolding the rollable substrate, ensuring the flatness of the screen.

Benefits of technology

This avoids changes in the position of the optical engine and the screen, ensures the flatness of the screen after it is unfolded, prevents the device from taking up too much space when not in use, and improves the display effect.
