Abstract

The embodiment of the invention provides a display panel, a display device and a driving method of the display device, relates to the technical field of display, and can solve the problem that aging of an OLED display panel is accelerated due to the fact that the current of the OLED display panel needs to increase in a high-brightness scene. The display panel comprises a first array substrate, a second array substrate and a liquid crystal layer; the first array substrate and the second array substrate are arranged to oppositely close; the liquid crystal layer is arranged between the first array substrate and the second array substrate; the display panel comprises multiple sub-pixel units; each sub-pixel unit comprises a colour film pattern, an electroluminescent layer and a driving electrode; the colour film pattern is arranged on the first array substrate; the electroluminescent layer is arranged on the second array substrate; the driving electrode is used for driving the liquid crystal layer and the electroluminescent layer; the driving electrode comprises a reflective electrode, a transparent electrode and a pixel electrode; the reflective electrode is positioned on the second array substrate and below the electroluminescent layer; the transparent electrode is over the electroluminescent layer; and the pixel electrode is positioned on the first array substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, organic electroluminescent diode) display panel has the characteristics of self-illumination, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display, so it is widely used in display field. [0003] For the existing OLED display panel, when used in a dark environment, the OLED display panel has a better display effect, and the main performance is: bright colors, darker black images and the like. However, when used outdoors or under bright ambient light, the OLED display panel will show strong reflected light, which is mainly due to the strong reflection effect of the anode metal electrode in the OLED display panel. Therefore, when the user uses it in an outdoor environment, the display effe...
