Problems solved by technology

[0004] However, in the process of implementing the present application, the inventors found that there are at least the following problems in the prior art: on the one hand, the flexible screen cannot be in contact with the outer surface of the rotating shaft because of the deformation resistance generated by the internal stress during the rotation of the flexible screen around the rotating shaft. The surface fit makes the first end of the flexible screen tilt up, which affects the flatness of the screen, and the tilting of the flexible screen will reduce the contact surface between the flexible screen and the shaft, which is prone to slipping on the surface of the flexible screen and the shaft during the winding process. use, it is easy to cause damage to the screen, thereby reducing the service life of the display device

Abstract

The embodiment of the invention provides a display device and electronic equipment, and belongs to the technical field of display. The display device comprises a sliding machine shell, a fixed machineshell, a flexible screen and a conveying assembly. The sliding machine shell is in sliding connection with the fixed machine shell. The conveying assembly comprises a rolling shaft, a pre-tighteningshaft and a transmission part. The rolling shaft and the pre-tightening shaft are both hinged to the sliding machine shell. The transmission part is fixed in the fixed machine shell. A first end of the flexible screen is fixed to the fixed machine shell, the flexible screen covers the outer surface of the top of the fixed machine shell, and a second end of the flexible screen winds the rolling shaft and is fixed to the transmission part. The pre-tightening shaft is located between the rolling shaft and the transmission part, and the outer surface of the top of the pre-tightening shaft abuts against the flexible screen. Thus, the outer surface of the pre-tightening shaft abuts against the flexible screen all the time, the contact area between the flexible screen and the rolling shaft is increased, meanwhile, the flexible screen is always subjected to supporting force of the pre-tightening shaft, and the flexible screen can be always matched with the outer surface of the rolling shaft under the effect of the supporting force of the pre-tightening shaft.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and electronic equipment. Background technique [0002] With the continuous development of display technologies, users have increasingly diverse demands on display effects of display devices. With the application of flexible display screens, display devices are increasingly pursuing practicability and personalization, such as changing the display ratio of the display device to realize switching between different functional modes of the display device. [0003] At present, the display device includes a flexible screen and a device casing, and a rotating shaft is arranged in the device casing, the first end of the flexible screen is fixed on the device casing, and the second end of the flexible screen is wound around the rotating shaft, and rotates through the rotating shaft , the area covered by the flexible screen on the device casing can be changed to ...
