An organic light emitting diode pixel arrangement structure

Abstract

The invention discloses an organic light emitting diode pixel arrangement structure, which is characterized in that it comprises: a first sub-pixel, a second sub-pixel and a third sub-pixel forming a matrix; two adjacent first sub-pixels are arranged to form a first sub-pixel A pixel group, two adjacent second sub-pixel groups are arranged to form a second sub-pixel group, and two adjacent third sub-pixels are arranged to form a third sub-pixel group; the first sub-pixel group, the second sub-pixel group The pixel group and the third sub-pixel group correspond to the square opening of the mask plate in the evaporation process, and there is an inclination angle between one side of the square and the horizontal line, and the inclination angle is not 0°, 90° or 180° °. By applying the technical solution of the present invention, the influence of the shadow effect can be reduced, and the aperture ratio and resolution can be improved conveniently.

Description

technical field [0001] The invention relates to the technical field of semiconductor display devices, in particular to an organic light emitting diode pixel arrangement structure. Background technique [0002] Organic Light Emitting Diode (OLED, Organic Light Emitting Diode) has become the third largest display after liquid crystal displays due to its display characteristics such as self-illumination, large viewing angle, wide color gamut, short response time, and high contrast ratio, as well as its advantages of thinness and flexibility. generation display technology. [0003] In traditional techniques, such as figure 1 As shown, an organic light emitting diode pixel arrangement structure usually consists of a plurality of pixel points 100, each pixel point includes a red (R) sub-pixel 101, a green (G) sub-pixel 102 and a blue (B) sub-pixel 103, The R, G, and B sub-pixels are arranged circularly in turn to form a matrix. R, G, and B sub-pixels are square, and the long an...

Problems solved by technology

If l1 and l2 are larger, the distance between the openings of the mask must be larger, so that the metal area between the openings will increase, thereby reducing the aperture ratio (ratio of the pixel light-emitting area to the total area of ​​the pixel), increasing The distance between the openings will also reduce the pixel resolution (PPI, Pixels Per Inch)
