Abstract
With the advent of the information society, full-color, high-resolution large-screen LED display panels because of its rich color, high brightness and adjustable, can be carried out and the screen editor, such as spots prominent feature of the application in all walks of life become more to the more general. Therefore, the general two-color LED dot matrix display, can display Chinese characters and a variety of common characters, such as information, can be applied to public places to the public release of the information.
The design of two-color LED dot matrix display 89C51 control through their shows, the output can be a particular color output can be two colors at the same time; can change the dynamic display of the mobile speed; also can change the display (left , down, diagonal movement, etc.).
Understanding as well as the display shows the control principle is the principle of design. The design of two-color display screen in monochrome developed from the basis, therefore, increase the width of the circumstances, the focus of this design is the design of color control circuit, as well as upper and lower sub-display screen.
