ZENG Zheng-lin, LIU Xue-man. LCD Module Based on FPGA Accelerating Graphics and Characters Processing[J]. , 2012,(3): 352-358 DOI: 10.3788/YJYXS20122703.0352.
Industrial Personal Computer (IPC) and LCD display is widely used
because of high-performance graphics cards in IPC.It is very convenient to design a human-computer interaction interface. However
in aerospace applications where real-time performance and reliability is most important
graphics and display integrated in LCD module is usually required to reduce the burden of processors and to improve the real-time performance of systems.This paper focuses on how to use FPGA to draw 2D graphics (including drawing point
drawing a line
circle
ellipse)that is based on Bresenham algorithm
and display dot matrix characters and bitmaps on the LCD screen
it also proposes a series of strategies about how to optimize display performance. Through simulation and practical application in a product
this LCD module based on FPGA is stable
and has good performance.It can be used in aerospace applications.
