Abstract
LCD has being used for displaying characters, pictures, and graphs in every industry. One difficult point is to display the graphs plotted real time with high efficiency and good quality. There are four kinds of main plotting algorithms, i.e., pointwise comparison interpolation method, digital differential interpolation method, midpoint interpolation method, and Bresenham interpolation method, for interpolating the straightline and arc while plotting graphs. Based on the contrast studies for the principles of four algorithms, this paper compared the interpolating efficiency while they are used to interpolate straightline and circle. Then a LCD display system with drive circuit was designed and manufactured for comparing the plotting quality and display effect. Finally, the optimized algorithms with highest efficiency and best quality for plotting were achieved for interpolating the straightline and circle with these four algorithms on the LCD. The research result will be helpful to selecting a best interpolation algorithm for LCD display.
