Bushma O. Reliability Improvement for Multiple-unit LED-based Bar Graph Display Devices

The construction of high reliable bar graph display was researched. The analysis of construction intrinsic to this group of devices at functional and structural levels, and also at a level of their element base is performed. The appropriate mathematical models are offered and tested. The original optimized double cycle structures for controlling bar graph display are developed and investigated. A number of display digital units is synthesized and analyzed. The minimized original converter of a binary normal code in a bar graph code is proposed and tested. The injection thermal interference of LEDs in multiple unit scale modules is experimentally found and investigated. Practical recommendations for hardware realization and parametrical optimization of the basic structural units for bar graph display devices are suggested.
