A Hangul input keyboard is provided to display all Hangul consonants and vowels by arranging keys in a fan shape, and easily and quickly combining the keys with an 'a' key placed at the center of the keyboard. A Hangul input keyboard includes a plurality of keys. Basic consonants and vowels of Hangul are assigned to each key. An 'a' key displays the consonant and the vowel changed according to an input frequency by functioning as an additional stroke key for the basic consonant and vowels. A double consonant key changes the consonant into a double consonant by receiving input. |
