Problems solved by technology

The limitation is that you cannot temporarily make any changes to the graphics before exposure to production
Method (2) simplifies the graphics filling process after decomposing the graphics, but still requires multi-step processing, which is cumbersome
And to ensure efficiency, the triangles obtained by polygon decomposition are not Delaunay triangles, and the graphics may be deformed due to calculation errors when the triangles are rasterized

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, (1) The vector data is first preprocessed by the CPU program, including closing the unclosed polygons, and copying the edges of all polygons into an array;

[0026] (2) Copy the array in step (1) to the GPU memory, run the GPU filling program, and then copy the result to the CPU memory after completion; among them, in the process of rasterizing vector graphics, use GPU general parallelism Computing technology, combined with figure 2 As shown, the specific calculation steps are as follows:

[0027] 1) Scale the coordinate unit of the vector graphics point, and dynamically adjust the coordinate unit of the vector point according to the difference in grid precision of different LDI models and the actual grid precision;

[0028] 2) Rasterization of the edges of the vector graphics: extract the pixel coordinates of each edge o...

Abstract

The invention discloses a vectorgraph rasterizing method for a digital micromirror display. A general parallel computing technique of a GPU (Graphics Processing Unit) is utilized in the process of rastering the vectorgraph. The method comprises the following specific calculation steps: 1) zooming a coordinate unit of a vectorgraph point, and dynamically adjusting a vector point coordinate unit according to the differences of different LDI (Laser Direct Imaging) model grid precisions and the actual grid precisions; 2) rasterizing the edges of the vectorgraph; extracting pixel coordinates after each edge of the vectorgraph is rasterized, and filling all pixel points, and collecting all point pixel coordinates beyond an upper top point; and 3) carrying out resorting and pair filling on the pixel points obtained in step 2). According to the vectorgraph rasterizing method provided by the invention, the vectorgraph rasterizing process can be accelerated to realize rasterizing; furthermore, the vectorgraph data can be allowed to change temporarily when the capacity is guaranteed, therefore the method has an extensive practical value and a marketing situation, and the efficiency of the overall industry can be beneficially improved.

Description

technical field [0001] The invention relates to a vector graphics rasterization method for digital micromirror display, and belongs to the technical fields of digital image processing technology of direct-write photolithography machine and GPU parallel development technology. Background technique [0002] Photolithography is used to print a pattern of features on the surface of a substrate. Such substrates may include chips used in the manufacture of semiconductor devices, various integrated circuits, flat panel displays (eg, liquid crystal displays), circuit boards, biochips, micromechanical electronic chips, optoelectronic circuit chips, and the like. [0003] DMD (Digital Micro mirror Device, digital micromirror device): Developed by Texas Instruments (TI), it is a very small mirror. These micromirrors are suspended and can be tilted to both sides by about 10-12°. Thereby, two working states of on and off can be formed. In order to obtain different brightness, the rate ...
