Abstract

The invention discloses a flexible curved surface display screen and a preparation method thereof. The flexible curved surface display screen is provided with a plane area and a curved surface area connected to the plane area; the flexible curved surface display screen comprises a flexible display panel, a supporting gasket and a flexible filling piece, wherein the flexible display panel extends from the plane area and is bent to the curved surface area; the supporting gasket is attached to and supported on the back of the flexible display panel and extends from the plane area to the curved surface area; and the flexible filling piece is arranged in the curved surface area and is filled between the supporting gasket and the flexible display panel, so that the flexible display panel is supported by the supporting gasket. A groove is formed in the surface of the side, facing the flexible display panel, of the supporting gasket, the groove is filled with foam rubber to form a flexible filling piece, an arc-shaped surface is formed on the flexible filling piece, and the arc-shaped surface is perfectly attached to the back of the flexible display panel. The foam rubber can be compressed, so that the profile tolerance zone of the supporting gasket can be ensured, and when the flexible display panel is bent, the flexible display panel can be perfectly attached to the supporting gasketduring bending, and the accuracy and precision during bending of the flexible display panel are guaranteed.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a flexible curved display screen and a manufacturing method thereof. Background technique [0002] With the development of the display industry, people are pursuing higher and higher screen-to-body ratios for display devices. Traditional LCD (Liquid Crystal Display, liquid crystal display) displays, due to the existence of the OLB (Outer Lead Bonding, outer lead bonding) area at the bottom of the screen , resulting in the inability to further increase the overall screen-to-body ratio. With the development of flexible OLED (Organic Light Emitting Display, Organic Light Emitting Display), by folding the OLB area of ​​the panel to the back of the panel (referred to as Pad bending technology), the lower frame of the screen is further reduced, and the overall screen ratio is increased. [0003] At this stage, mobile phones attract customers because of new appearance and struct...
