Data processing terminals, icon badges, and methods of making and using the same

A method of displaying a plurality of icons of a plurality of apps on a display unit of a data processing terminal which is installed with said apps and which receives contents which are related with said apps, wherein an unread content is a content which said terminal has received after a user of said terminal has finished running said apps and which, therefore, said user has not confirmed, wherein said unread content is either an unread labeled content or an unread unlabeled content, wherein said unread labeled content is a first content which a sender of said first content labels said user as a labeled receiver, and wherein said unread unlabeled content is a second content which said sender of said second content has not labeled said user as said labeled receiver, said method comprising the steps of:

• a receiving step wherein said terminal receives said unread contents related to a certain app;
• a label checking step wherein said terminal determines whether said unread contents include at least one unread labeled content;
• a classifying step wherein said terminal classifies said certain app as a first group app when said unread contents includes said at least one unread labeled content, and wherein said terminal classifies said certain app as a second group app when said unread content does not include said unread labeled content;
• and
• a displaying step wherein said terminal displays said first group of said apps and said second group of said apps in different portions of said display unit,
• whereby said terminal allows said user to easily identify said first group of said apps each of which has received said at least one unread labeled content,
• wherein the method further comprises displaying said unread labeled content and unread unlabeled content in one of different fonts, colors, thickness, sizes, and backgrounds.
