Abstract
PURPOSE: To realize display with a small number of input keys for the alphabet and the kana (Japanse syllabary) letters by grouping the characters and registering them in time division for the wristwatch or the like.
CONSTITUTION: The alphabet is grouped with every two letters to input key 4, and the addresses are generated 6 for the characters of two letters in accordance with the output given from key 4. The pulse of the fixed duration is delivered from divider circuit 8 via the output gate 7 and by the operation signal of key 5. As a result, gates 9 and 11 are controlled, and the addresses of two letters are supplied to OR gate 12 in time division. At the same time, the character signals of the two letters are produced in time division from circuit 13 to drive 14 liquid crystal display substance 15. Thus the alphabet can be registered with a small number of keys.
