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

Embodiment Construction

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0044] figure 1 It is a flow chart of the method for dividing a layout and generating random graphics according to the present invention, which will be referred to below. figure 1 , the method of dividing the layout and generating random graphics of the present invention will be described in detail.

[0045] First, in step 101, a pixel unit is specified for identifying the pixel array in the layout.

[0046] Preferably, the name of the pixel unit is specified, including library name, unit name and view name.

[0047] Preferably, the name of the specified pixel unit further includes the specified process layer used for the graphics representing the outline in the pixel unit, so...

Abstract

A method for dividing a layout and generating random graphics, comprising the following steps: 1) identifying the display area and the position of each pixel unit according to specified pixel unit information; 2) determining the cutting line according to the specified cutting line process layer Position; 3) Divide the display area according to the cutting line; 4) Set the number of rows / columns for generating mosaic graphics; 5) Set the number of mosaic graphics generated in the row / column direction to account for the pixel units in the row / column The ratio of the number; 6) generating the mosaic pattern. The method for dividing the layout and generating random graphics of the present invention can accurately realize the division of the display area, and at the same time efficiently create mosaic graphics satisfying strict random characteristics and numbers.

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] With the photolithography of large-sized panels, when the size of the panel exceeds the size of the exposure machine, if the boundary of the two exposures is a straight cut, the human eye can clearly identify 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 the 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 an outline layer, if a pixel is to be exposed in shot A, its layer graphic is retained in the shot A cell, otherwise it is completely covered with the same layer rectangle with the same size as the pixel out...
