Problems solved by technology

Due to the large number of pixel units in large-size panels, mosaic graphics are required to be generated at any time, so they cannot be created in an array, so the efficiency is very low, and it is often difficult to ensure good randomness

Abstract

The invention discloses a method for segmenting a layout and generating a random graph. The method comprises the following steps: 1) identifying a display area and the position of each pixel unit according to specified pixel unit information; 2) determining the position of the cutting line according to a specified cutting line process layer; 3) segmenting the display area according to the cuttingline; 4) setting the row / column number of the generated mosaic pattern; 5) setting the ratio of the number of mosaic patterns generated in the row / column direction to the number of pixel units in therow / column; and 6) generating the mosaic pattern. According to the method for segmenting the layout and generating the random graphs, a display area can be accurately segmented, and meanwhile the mosaic graphs meeting strict random characteristics and the number can be efficiently created.

Description

technical field [0001] The invention relates to the technical field of layout design, in particular to a method for dividing a layout and generating random graphics. Background technique [0002] When performing photolithography on a large-size panel, when the size of the panel exceeds the size of the exposure machine, if the boundary between the two exposures is a straight cut, the human eye can clearly distinguish the exposure dividing line in the light-emitting area of ​​the screen after the finished product. Because the human eye is more sensitive to the shape of a long strip. [0003] In order to avoid the above problems, it is necessary to perform fuzzy cutting at the exposure boundary. The method is to randomly select the pixel (pixel unit) for photolithography. Specifically, for a certain outline layer, if a certain pixel is to be exposed in shot A, its layer graphics will be kept in the shot A cell, otherwise it will be completely covered with a rectangle of the s...
