AI Technical Summary

Technical Problem

Existing transparent display panels have insufficient light-shielding structures and lack effective driving mechanisms, making it difficult to reliably open and close transparent display panels.

Method used

The system employs a combination of pulleys and rollers. Through the interaction between the pulleys and rollers, the light-shielding film is wound and unwound. Combined with the pulley support and side frame, a frame structure is formed, which drives the light-shielding film to block light from the transparent display panel.

Benefits of technology

The durability of the light-shielding film for the light-shielding driving mechanism of the transparent display panel has been improved, enabling reliable opening and closing and effective light shielding of the transparent display panel.

Abstract

A display device is disclosed. The display device may include: a display panel for displaying images and having light transmittance; a transparent panel facing the display panel; a side frame extending elongated along the side edge of the display panel and connected to the transparent panel; a belt built into the side frame and movable along the length direction of the side frame; a rod extending elongated in a direction intersecting the side frame and fixed at one end to the belt; a rotatable roller near the lower edge of the display panel connected to the side edge of the display panel and extending elongated along the lower edge of the display panel; a light-shielding film fixed at one end to the rod and connected to the roller at the other end, which wraps around or unwraps around the roller if the rod moves; an upper pulley located on the upper side of the side frame for winding the belt; a drive pulley near the lower side of the side frame for winding the belt; and a pulley support member supporting the rotation axis of the upper pulley and connected to the side frame.
