В роботі розглянуто можливість створення пристрою для формування динамічно розгорнутого
кольорового зображення з невеликою кількістю діодів. Запропоновано конструкції блоків індикації для формування
динамічно розгорнутого зображення (7-колірного та повноколірного). Для запропонованих блоків індикації
розроблено електричні схеми, блоки живлення, генерації та керування, а також конструкції лінійок зі
світлодіодами. Розроблено програмний код для формування зображення. Виготовлено стенд для формування
динамічно розгорнутого кольорового зображення та підтверджено працездатність блоків індикації.
The aim of the research is to develop a device for dynamically-expanded color image formation with a small number of diodes. Design of the indication unit for the formation of dynamically-expanded 7-color image has been put forth. For imaging, it uses RGB diodes and shift register that are installed on a special moving line, imaging being done with a group of RGB diodes pixels, the color of which is set by a program via control system depending on the speed of their motion and plane or space positioning coordinates. Moreover, a design of indication unit for the formation of full-color dynamically-expanded image, in which full spectrum of each RGB diode is set with a program via a chip of signal pulse-width modulation has been proposed. Electric circuits, power, generation, and control units as well as line construction units with light-emitting diodes have been developed for the proposed indication units. After electric circuits have been checked, a number of works including elaboration of a model of printed circuit boards, installation, and development of experimental samples have been done. Project work was done in OrCADCapture automated design system taking into account general recommendations regarding development and design of electronic control systems. Several ways of light-emitting diodes installation have been suggested. Depending on the number of diodes on a line, distance between them, and the system of signal formation, an image of various resolutions and color spectrum can be obtained. A program code for imaging has been developed. The system of dynamically-expanded image formation was installed on a bicycle wheel for experimental research. As a result of the research, parameters of indication units have been calculated and their working capacity has been proven.
