Example Embodiment

[0030] Some vocabulary is used in the specification and claims to refer to specific components. Those skilled in the art will appreciate that hardware manufacturers may call with different nouns. This specification and claims do not use the difference between the name as a differential component, but is used as a distinction between the components in functional differences. As mentioned in the presentation and claims, "including" is an open term, so it is explained to "including but not limited to". "Properly" refers to the technical problem can be solved within a certain error range within a certain error range within a certain error range. In addition, the term "coupling" here includes any direct and indirect electrical coupling means. Thus, a first device is coupled to a second apparatus in which a first device is described in which a first device can be directly electrically coupled to the second device or indirectly electrically coupled by other devices or coupling means. Con...

Abstract

The invention discloses a display panel, a display device and a display method, and relates to the technical field of display. The display panel comprises a first display area and a second display area, the first display area is a plane area, and the second display area is a curved surface area. The display panel further comprises an underlayment substrate; pixel light-emitting elements which are located on the side, close to the light-emitting face of the display panel, of the underlayment substrate, and each comprise an anode, a pixel light-emitting layer and a cathode which are sequentially arranged in a stacked mode; and compensation layers which are located in the second display area, and are located on the sides, away from the light-emitting face of the display panel, of the pixel light-emitting elements. In the direction perpendicular to the light-emitting face of the display panel, the orthographic projections of the compensation layers on the underlayment substrate are at least partially overlapped with the orthographic projections of the anodes of the pixel light-emitting elements of two colors at most on the underlayment substrate. The compensation layers are arranged on the anodes of the pixel light-emitting elements, so that the compensation layers and the anodes form capacitor structures, the brightness of each pixel light-emitting element is compensated, and the problem of color cast under a large visual angle is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel, a display device and a display method. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has become one of the most competitive technologies in the new generation of display devices due to its wide color gamut, high contrast ratio, energy saving, and foldability. It has a wide range of applications , for example, smart wearable devices, vehicle-mounted devices and smart home appliances. [0003] With the continuous development of display technology, the development process of flexible display panels is gradually accelerated. Due to its low power consumption, bendable and foldable characteristics, flexible display panels will have a profound impact on the application of wearable devices, and in the future, flexible display panels will also be widely used with the continuous penetration of personal smart te...
