Problems solved by technology

However, during the use of the roll-type display device, when a part of the flexible screen is stretched, the overall thickness of the flexible screen wound on the rotating shaft decreases, and the relative position of the rotating shaft and the opening is fixed, resulting in a gap between the flexible screen and the opening. Or friction occurs on the inner wall of the reel, resulting in scratches on the flexible screen, etc.

Abstract

The invention discloses a reel-type display device, which includes a reel and a flexible screen. The reel includes a shell and a rotating shaft rotatably arranged in the shell, the shell is provided with an opening in the first direction, the flexible screen is wound on the rotating shaft and provided with a connecting end and a telescopic end, the connecting end is connected to the rotating shaft, the telescopic end is configured to be expanded and retracted by the opening, wherein sliding grooves are formed in the positions, corresponding to both ends of the rotating shaft, of the inner wall of the shell correspondingly, the sliding grooves extend in the second direction, the second direction intersects with the first direction, and the two ends of the rotating shaft are slidably matched with the two sliding grooves correspondingly. The reel-type display device further includes a driving mechanism, the driving mechanism is configured to drive the rotating shaft to slide along the sliding grooves to make the part of the flexible screen unwound on the rotating shaft keep extending in the first direction according to the telescopic state of the flexible screen.

Description

technical field [0001] The present disclosure relates to the technical field of display devices, in particular to a scroll-type display device. Background technique [0002] Such as figure 1 As shown in , it representatively shows a partial cross-sectional view of a conventional scroll-type display device. Wherein, the reel type display device mainly includes a reel 101 and a flexible screen 104, the reel 101 is provided with a rotating shaft 102, the reel 101 is provided with an opening 103, the flexible screen 104 is wound on the rotating shaft 102, and one end of the flexible screen 104 is connected to the rotating shaft 102 , the other end can be stretched by the opening 103. However, during the use of the roll-type display device, when a part of the flexible screen is stretched, the overall thickness of the flexible screen wound on the rotating shaft decreases, and the relative position of the rotating shaft and the opening is fixed, resulting in a gap between the fle...
