Abstract

The embodiment of the invention discloses an organic light-emitting display panel and device. At least a part of the area of the organic light-emitting display panel is a bent surface or a curved surface, and the organic light-emitting display panel is provided with a front view surface; the organic light-emitting display panel comprises a plurality of arc-shaped organic light-emitting units, eacharc-shaped organic light-emitting unit is provided with an arc-shaped light emergent surface, and the central axis of each arc-shaped organic light-emitting unit is perpendicular to the front view surface. According to the embodiment of the invention, the problem of non-uniform display brightness of the existing curved organic display panel is solved, the display brightness of the organic light-emitting display panel is ensured to be consistent when the organic light-emitting display panel is observed from each angle, the color cast is avoided, the brightness uniformity of the display panel is improved, and the display quality is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to an organic light emitting display panel and a device. Background technique [0002] With the development of display technology, various types of display panels, such as liquid crystal display panels, organic light-emitting display panels, and electronic paper display panels, are more and more widely used. Among them, the organic light emitting display panel includes an organic light emitting diode (Organic Light Emitting Diode, referred to as OLED) display panel. The OLED display panel has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high response speed. In addition, the organic light-emitting display panel can be made into a flexible display panel, which is easy to bend. [0003] For a curved organic light-emitting display panel or an organic light-emitting display panel...
