Abstract

The invention provides a flexible OLED display panel, which comprises a backboard, a flexible substrate and a signal line layer. The backboard comprises a first backboard and a second backboard. The flexible substrate is arranged on the backboard. The flexible substrate comprises a first region corresponding to the first backboard, a second region corresponding to the second backboard and a bending region connecting the first region and the second region. The signal line layer is arranged on the flexible substrate. In the bending region, a groove is formed in the side, away from the signal line layer, of the flexible substrate. By forming the groove in the bending region, bending radius of the flexible OLED display panel can be reduced, size of the border area is reduced, and screen-to-body ratio is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED display panel. Background technique [0002] With the development of technology in the display industry, full screen technology has become a major development trend, and narrow bezel design of display panels is becoming more and more important. [0003] The structure of the flexible OLED display panel in the prior art in the bent state is as follows: figure 1 As shown, it includes a first backplane 10, a second backplane 20, and a flexible panel 30 arranged on the first backplane 10 and the second backplane 20, the flexible panel 30 includes a bending area 31, and the The flexible panel 30 in the bending area 31 has a semicircular structure. This design can better balance the stress of the bending line, but the bending radius R is too large, which limits the minimum design size of the frame area of ​​the display panel and cannot meet the design of a full screen....
