12. A display apparatus comprising: an inputter configured to receive a user command input; a controller configured to: identify a first attribute value of a font effect to be applied to a character input through the inputter according to at least one of a characteristic of the character and a characteristic of the display apparatus, render the font effect based on the identified first attribute value, and apply the rendered font effect based on the identified first attribute value to the character input through the inputter, wherein the font effect comprises a glow effect for adjusting a filtering intensity of a border of the character; and an outputter configured to output the character to which the font effect is applied, wherein the identifying the first attribute value of the font effect comprises reducing the glow effect by reducing the filtering intensity of the glow effect such that the filtering intensity of the glow effect decreases as a screen resolution characteristic of the display apparatus decreases, and wherein in response to a size of the character to which the rendered font effect is applied being changed, the controller identifying a second attribute value of the font effect according to the changed character, and applying the font effect based on the second attribute value to the character.
