Title
(EN) Flexible display device
(ZH) 柔性显示装置
Abstract
(EN) The invention provides a flexible display device. The flexible display device comprises an outer frame, a first supporting plate mounted on the outer frame, a second supporting plate connected to thefirst supporting plate, a reel device connected to the second supporting plate and arranged at the edge of one side of the second supporting plate and far away from the first supporting plate, a rotating shaft assembly mounted on the outer frame, and a transmission assembly. One end of the transmission assembly is connected to the rotating shaft assembly, the other end of the rotating shaft assembly is connected to the reel device, and the rotating shaft assembly is meshed with the second supporting plate through the transmission assembly; when the second supporting plate and the first supporting plate are oppositely unfolded or mutually combined, the reel device and the rotating shaft assembly are driven by the transmission assembly to rotate at the same time. Through the transmission mode that a gear and rack mechanism is matched with a pull wire, stable transmission of the screen in the stretching or retracting process is guaranteed, the flexible display screen is prevented from being pulled and floated, and the service life of the flexible display screen is prolonged.
(ZH) 本发明提供一种柔性显示装置,包括外框架;第一支撑板,安装于所述外框架;第二支撑板,连接至所述第一支撑板;卷轴装置,连接至所述第二支撑板,且设于所述第二支撑板的一侧边缘处远离所述第一支撑板;转轴组件,安装于所述外框架;以及传动组件,其一端连接于所述转轴组件上,转轴组件其另一端连接于所述卷轴装置上,所述转轴组件通过所述传动组件与所述第二支撑板相啮合;当所述第二支撑板与所述第一支撑板相对展开或者相互合并时,所述卷轴装置和所述转轴组件在所述传动组件带动下同时转动。本发明通过齿轮齿条机构配合拉线的传动方式,保证屏幕在拉伸或收缩过程中的平稳传动,避免柔性显示屏被拉扯、起浮,提升柔性显示屏的寿命。
