Abstract

The invention discloses a display device. The display device comprises a first folding rack, a second folding rack, a first supporting plate, at least one second supporting plate, at least one pre-tightening assembly and a flexible display screen, and the second folding rack and the first folding rack rotate relatively. The first supporting plate is arranged on the first folding rack and the second folding rack and comprises a bending structure. And the bending structure is connected with the first folding rack and the second folding rack. The at least one second supporting plate is at least arranged on one side of the first supporting plate. And the at least one pre-tightening assembly is connected with the second supporting plate. The flexible display screen is arranged on the first supporting plate and the at least one second supporting plate and connected with the second supporting plate. The at least one pre-tightening assembly is used for providing a pre-tightening force for the flexible display screen.

Description

Technical field [0001] TECHNICAL FIELD The present application relates, in particular, is a display device having a biasing assembly. Background technique [0002] OLED (organic light emitting diode, OLED) display technology has matured greatly promoted the clamshell phone, notebook computer folding commercial market. Folding display products by consumers pro-gaze. However, the issue has been one of the main crease folding mobile phone market influence to further expand. Currently, on how to effectively reduce mobile phone OLED screen crease question, yet to find a reasonable solution. [0003] Factors OLED display crease problem is more complex, including the following reasons. Since the display device is folded, the folding mobile phone, for example, unreasonable design of the hinge, resulting in the mobile phone during use, the screen can not be completed with the natural fold expansion action. Note that the mobile phone is present between the folding screen and block structur...
