Problems solved by technology

[0004] There are multiple components distributed on the flexible circuit board, and multiple components are usually concentrated in a small area on the flexible circuit board. In order to avoid damage to the components and prevent the components from being separated from the flexible circuit board, the flexible circuit board will be separated by The flat state is installed in the hollow reel, so that the hollow reel needs to have a larger diameter to accommodate the flexible circuit board, resulting in a larger volume of the hollow reel for the flexible display device

Abstract

The invention provides a flexible display device, and belongs to the field of display equipment. The flexible display device comprises a hollow scroll, a flexible display panel and a flexible circuitboard, the flexible display panel is positioned on the hollow scroll, the flexible circuit board is positioned in the hollow scroll, the flexible circuit board comprises a flexible body and a plurality of components, the flexible body is provided with a first side edge connected to the flexible display panel and a second side edge opposite to the first side edge. The flexible body is provided withat least two component arrangement areas spaced in the arrangement direction of the first side edge and the second side edge and a wiring area connected between the adjacent component arrangement areas, and the multiple components are located in the at least two component arrangement areas. The wiring area between the two component arrangement areas of the flexible body is in a bent state, so that the two component arrangement areas are not coplanar, normal arrangement of the components can be guaranteed, the flexible circuit board can be placed in a hollow scroll with a smaller diameter, andthe diameter of the hollow scroll can be reduced.

Description

technical field [0001] The present disclosure relates to the field of display devices, in particular to a flexible display device. Background technique [0002] As an important application technology of OLED (Chinese name: Organic Light-Emitting Diode, English name: Organic Light-Emitting Diode), the flexible display device has obtained important development in recent years. Compared with traditional display devices, flexible display devices have significant advantages, such as lighter and thinner volumes and lower power consumption, and because flexible display devices are bendable and flexible, their application scenarios are becoming wider and wider. [0003] In the related art, a flexible display device usually includes a hollow reel, a flexible display panel, and a flexible circuit board connected to the flexible display panel. The flexible circuit board is located inside the hollow reel, and the flexible display panel is located outside the hollow reel. The flexible di...
