Problems solved by technology

At this time, the flexible display screen 92 produces serious stress concentration, and the local tensile stress rises sharply, which leads to the failure of the flexible display screen 92 due to the breakage of the internal circuit due to the stress concentration, and reduces the curling life of the rollable display device.

Abstract

The invention provides a reel and a display device. The display device comprises the reel, the reel comprises a reel body, the reel body is cylindrical, a first circle of installation groove is formedin the reel body in the extending direction of the length of the cylinder, and the depth of the first circle of installation groove is matched with the thickness of an installed flexible display screen. The flexible display screen is wound around the rell body from the first circle of installation groove until the first circle is finished; the inner side face of a second circle of the flexible display screen and the outer side face of a first circle of the flexible display screen do not generate section difference, it is guaranteed that the flexible display screen does not generate the stressconcentration phenomenon in the curling process, the stress value borne by the flexible display screen in the drawing process of the display device is reduced, the failure risk of the flexible display screen is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a scroll and a display device. Background technique [0002] At present, people are increasingly dependent on electronic products such as mobile phones, tablet computers, and smart wearable devices. In order to enhance user experience and enhance product competitiveness, the use of large screens has become a development trend. For the inconvenience of carrying large-screen electronic equipment, a rollable electronic display device emerges at the historic moment. When not in use, the electronic display screen can be rolled into the reel and stored in a small-sized form, which is easy to carry; Pull out from the reel. With the development of flexible electronic display technology, research on the structure of rollable devices is also underway. [0003] Such as figure 1 As shown, an existing display device 90 includes a scroll 91 and a flexible display 92 . The reel 91 is a st...
