Abstract

The invention provides an OLED display panel and an OLED display device. The OLED display panel comprises an array substrate, an OLED device layer, a thin film packaging layer, a touch layer and a color filter layer, the OLED device layer is arranged on the array substrate, and the OLED device layer comprises a plurality of light emitting units; the thin film packaging layer is arranged on the light emitting side of the OLED device layer; the color filter layer comprises a plurality of blocking units and a plurality of first openings formed among the blocking units, color filters are arrangedin the first openings, and the colors of light rays allowed to penetrate through the color filters are the same as the light-emitting colors of the corresponding light-emitting units; the touch layerand the color filter layer are sequentially stacked in the thin film packaging layer. According to the OLED display panel provided by the invention, the touch layer and the color filter layer are arranged in the thin film packaging layer, so that the problems of too fast brightness attenuation and color cast under a large viewing angle can be improved, the thickness of the display panel can be reduced, and flexible display is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] Compared with liquid crystal display devices, Organic Light Emitting Diode (OLED) display panels have many advantages such as self-illumination, fast response speed, low-voltage drive, high brightness, and thinness, so they have gradually become the mainstream in the display field. [0003] When the OLED display panel is displaying, external ambient light will irradiate the OLED display panel, and will be reflected out of the OLED display panel by metal electrodes inside the OLED display panel, resulting in a decrease in the contrast of the OLED display panel. In view of this, at this stage, a circular polarizer is usually installed on the light-emitting surface of the OLED display panel, and the circular polarizer is used to prevent part of the external ambient light from passing through the circula...
