Abstract

The application discloses an OLED display panel, comprising: a base substrate, an array structure layer, an organic light emitting layer, a thin film encapsulation layer, a touch screen layer and a polarizer layer, wherein the array structure layer, the organic light emitting layer and the thin film encapsulation layer are formed on the base substrate in such a manner as to be spaced apart from each other, and at least one of the touch screen layer and the polarizer layer is located in the thin film encapsulation layer. Therefore, the inorganic material layer in the thin film encapsulation layer is replaced by the touch screen layer and / or the polarizer layer disposed in the thin film encapsulation layer to reduce the number of layers of the OLED display panel and reduce the thickness of the OLED display panel, thereby shortening the optical path and effectively improving the luminous flux efficiency.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] OLED display panels have gradually become the mainstream in the field of display technology due to their low power consumption, high color saturation, wide viewing angle, ultra-thin and foldable properties. In order to ensure various excellent performances of the OLED display panel, a thin film encapsulation layer is provided in the OLED display panel, which includes a plurality of overlapping inorganic material layers and organic material layers. Wherein, the inorganic material layer is used to prevent the intrusion of moisture and oxygen, and the organic material layer is used to reduce the pressure on the inorganic material layer and prevent the inorganic material layer from cracking or even breaking due to external force. The inventors of the present application have discovered in the ...
