Abstract

The invention provides an OLED (Organic Light Emitting Diode) display panel and an OLED display device. The OLED display panel comprises a substrate, a driving circuit layer, a planarization layer and a light-emitting functional layer, the OLED display panel comprises light-emitting areas and an electronic element arrangement area located between the light-emitting areas, a via hole is formed in at least one of the whole of the electronic element arrangement area, the planarization layer and a pixel definition layer and the driving circuit layer, a filling material is arranged in the via hole, and the light-emitting functional layer is arranged on the substrate. And the filling material is used for converging light rays when the light rays are transmitted to the driving circuit layer from the pixel definition layer. The via hole is formed in at least one of the planarization layer and the pixel definition layer of the electronic component setting area and the driving circuit layer, and the filling material is arranged in the via hole, so that the filling material can converge the light transmitted from the pixel definition layer to the driving circuit layer, scattering and reflection of the light are avoided, and the display quality is improved. The transmittance of light in the OLED display panel is improved, so that the electronic component can receive enough light and can work normally.

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 (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices are widely used due to the advantages of self-illumination, flexibility and the like. In order to increase the screen-to-body ratio of existing display devices, the sensing device is placed under the display screen. However, due to the design of the existing display device, when the external light enters the OLED display device, it needs to pass through a film layer with a high refractive index. Then it reaches the low-refractive-index film layer, causing the light to be totally reflected and part of the light to be scattered, which makes the sensing device unable to obtain sufficient light and causes the sensing device to fail to work properly. [0003] Therefore, the existing OLED display device has the tec...
