Embodiment Construction

[0028] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [up], [down], [front], [rear], [left], [right], [inner], [outer], [side], etc., are only for reference Additional schema orientation. Therefore, the directional terms used are for describing and understanding the present invention, not for limiting the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0029] The present invention provides a flexible OLED display panel to alleviate the technical problem that the bending radius of the existing flexible OLED display panel is too large.

[0030] like figure 2 As shown, it is a schematic diagram of the first structure of the flexible OLED display panel provided by the embodiment of the present invention. The flexible OLED display pane...

Abstract

The present invention provides a flexible OLED display panel, which includes a backplane, a flexible substrate, and a signal line layer. The backplane includes a first backplane and a second backplane; the flexible substrate is disposed on the backplane, and the flexible substrate includes corresponding a first area of ​​the first backplane, a second area corresponding to the second backplane, and a bending area connecting the first area and the second area; the signal line layer is arranged on the flexible substrate; wherein, in the bending area Inside, a groove is formed on one side of the flexible substrate away from the signal line layer. By forming grooves in the bending area, the bending radius of the flexible OLED display panel can be reduced, thereby reducing the size of the frame area and increasing the screen ratio.

Description

technical field [0001] The present invention relates to the field of display technology, and 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 the main development trend, and the narrow border design of the display panel 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 disposed on the first backplane 10 and the second backplane 20. The flexible panel 30 includes a bending area 31. The flexible panel 30 in the folding area 31 is a semicircle structure, which can better balance the bending line stress, but the bending radius R is too large, which limits the minimum design size of the display panel frame area and cannot meet the design of the full screen. [0004...
