An organic electroluminescence display panel and display device

Abstract

The present disclosure provides an organic electroluminescent display panel and a display device, which increases the area of ​​the opening region of the pixel defining layer so that it is not restricted by the evaporation shadow, and at least part of the evaporation shadow, that is, the middle film of the monochromatic organic light-emitting film Part of the edge area with uneven thickness falls into the opening area as an effective light-emitting area, and the color resistance corresponding to the light-emitting color of the monochromatic organic light-emitting film in the filter layer is used to filter the light emission in the opening area to ensure that light is emitted from each sub-pixel The color will not appear color cast problem. Since the color purity is ensured by the filtering function of the color resist, the evaporation shadow can be used as an effective light-emitting area to increase the pixel aperture ratio, thereby reducing the power consumption of the display panel. Moreover, the use of the filter layer can replace the existing polarizer to reduce the reflection of external ambient light. The light transmittance of the filter layer is generally higher than that of the polarizer, so the light output of the organic electroluminescent display panel can be improved. efficiency to reduce the power consumption of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display panel and a display device. Background technique [0002] At present, in the organic electroluminescent display panel, the evaporation process is mainly used to produce the monochrome organic film layer, and the evaporation shadow (Shadow) will inevitably appear during the evaporation process using the high-precision metal mask FMM. The organic film layer emits light in the edge area with uneven film thickness, that is, the evaporation shadow area, which will cause color shift, so the edge area cannot be used as an effective light-emitting area in the prior art. In this way, the opening area of ​​each sub-pixel in the pixel defining layer (i.e. the effective light-emitting area of ​​the sub-pixel) is limited by the evaporation shadow, and the opening area in the pixel defining layer can only have the size of the central area of ​​the monochr...
