Problems solved by technology
Since the common electrode usually has a certain reflective ability, and the spacer column structure arranged in an array makes the common electrode form a grating structure with a fixed period, so as to produce regular reflection on the external light, and it is easy to cause rainbow patterns on the display panel at this time. Interfering with the display screen, thus affecting the display effect of the display panel

The embodiment of the present invention discloses a mask and an organic light-emitting display panel. The mask is used to prepare a common electrode of the organic light-emitting display panel. The organic light-emitting display panel includes a plurality of light-emitting units and a plurality of The spacer column between the light-emitting units, the mask plate includes: a mask version body; a common electrode opening located on the mask version body; the common electrode opening correspondingly exposes the common electrode; A plurality of shading strips in the opening, one end of the shading strips is connected to the mask version body; when the mask is masked, the orthographic projection of each of the shading strips on the organic light emitting display panel A plurality of said spacer columns are covered. The embodiments of the present invention can eliminate the rainbow stripes on the organic light emitting display panel, which is beneficial to provide the display effect of the organic light emitting display panel and improve user experience.
Description
technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a mask and an organic light-emitting display panel. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED) display panel has gradually become a popular emerging flat-panel display. It has the advantages of being made into a flexible panel and a simple manufacturing process, so it has been widely used in various flat display products. [0003] A conventional OLED display panel includes a plurality of organic light emitting units as display pixels to display images. Wherein, each organic light-emitting unit is composed of two electrode layers and a light-emitting layer located between the two electrode layers, and the two electrode layers and the light-emitting layer are stacked on the substrate. In order to reduce the manufacturing process and simplify the driving method, a common electrode is usually formed in the OLED display panel, ...
