Character input method and display apparatus

A display apparatus comprising:

• a display;
• an inputter;
• and
• a controller configured to:
• control the display to display an input window and a virtual keyboard including a plurality of keys, each of the plurality of keys having a corresponding character,
• based on a stroke input on a key among the plurality of keys being received through the inputter, control the display to display a character of the key in the input window,
• identify at least one suggestion character related to the character of the key, and
• control the display to display at least one suggestion key including the at least one suggestion character at a space on the virtual keyboard such that the at least one suggestion character and characters of keys adjacent to the key do not overlap,
• wherein based on the stroke input on the key being received, a size of the keys adjacent to the key is enlarged and the characters of the keys in the enlarged keys are moved away from the character of the key, and each enlarged key of the enlarged keys overlaps with neither the key that received the stroke input nor a key that is adjacent to the enlarged key and is on an opposite side of the enlarged key with respect to the key that received the stroke input, and
• wherein the controller is configured to control the display to display the each enlarged key of the enlarged keys to overlap with a corresponding suggestion key of the at least one suggestion key and to display each of the moved characters not to overlap with each of the at least one suggestion character in the at least one suggestion key.
