Design of N-Segmented Display system for Bengali vowels

Abstract

Different segmented display systems have been proposed for representing Bangla and English alphabets and numerals in past few years. In order to distinguish Bengali Vowels in precise form, they must be represented with their unavoidable curved shapes. Accurate recognition of Vowels is difficult due to their complex shapes. In this paper, we tried to represent a total of 11 Bangla vowels in simpler and accurate look. To improve their accuracy, we have proposed a 58-segmented display. And we derived a very simple, scientific logic to find segments out of matrix display. We have introduced a 4-bit input line to represent all the Bengali Vowels, analyzed all the 58-sements against each and every Vowel, and designed the suitable circuit for each of the 58 segments.
