Text display refers to the way that words and letters appear on a screen or printed page. When you look at a computer screen or a book, you see words and letters that are made up of little shapes and lines called "characters." A character is a special symbol that represents a letter, number or other symbol.
Your computer or device has software that knows how to take the words, letters and symbols that you type and turn them into characters that can be displayed on a screen. To create each character, the software uses a set of instructions called a "font". Fonts are like different sets of stamps that can be used to imprint shapes into the paper or display them on the screen.
Fonts dictate how each character looks, the size, the style and the spacing between them. When you choose a font for your text, you are picking out what style you want your letters to look like.
The way that text is displayed can also be affected by the color, the contrast, and the brightness settings on your screen. These settings control how easily you can read the text on the screen.
In summary, text display is the way that letters and symbols are made to look on a computer screen, monitor or printed page through a set of instructions called fonts. The style, size and spacing of each character can all be adjusted to make reading easier on your eyes.
