Pixel arrangement structure, mask plate assembly and display panel

Abstract

The invention discloses a pixel arrangement structure, a mask plate assembly and a display panel, the pixel arrangement structure comprises a plurality of repetitive units arranged in an array, the repetitive units are N-sided, N is greater than or equal to 4, and N is an even number; the repeating unit is divided into N pixel units by connecting lines between midpoints of N edges of the repeatingunit and the center of the repeating unit, the pixel units are quadrilateral, each pixel unit comprises a vertex angle close to the center of the repeating unit, a corner adjacent to the vertex angleand a diagonal opposite to the vertex angle, and the vertex angle and the corner are provided with first sub-pixels; and the adjacent N-polygon repeating units are connected through edge butt joint.The first sub-pixels, located at the same position, of the different pixel units can share the evaporation openings in the same mask plate for evaporation, the opening area of the evaporation mask plate is effectively increased, and the manufacturing difficulty of the evaporation mask plate process is reduced. A gap does not need to be reserved when the adjacent first sub-pixels are evaporated, and high-resolution display can be achieved while the aperture opening ratio is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a pixel arrangement structure, a mask plate assembly and a display panel. Background technique [0002] In the display industry, as people's requirements for display effects gradually increase, OLED (Organic Light Emitting Diode, organic light-emitting diode) display performance will also continue to improve; among them, resolution and aperture Rate are two important indicators of device performance. For an OLED device, each pixel generally includes three sub-pixels (red, blue, and green). To avoid color mixing, the aperture ratio will be reduced while the resolution is increased; therefore, based on the existing pixel arrangement, it is difficult to achieve high-quality display with high resolution and high aperture ratio at the same time. [0003] Therefore, there is an urgent need for a new pixel arrangement structure, mask assembly and display panel....
