How can I add lyric display on my player (with lyric display function)?

 

The player will display lyric from a LRC file which normally came with your MP3 song. 

LRC is a computer file format that synchronizes song lyrics with an audio file, such as MP3. When an audio file is played with certain music players on a computer or on modern digital audio players, the song lyrics are displayed. The lyrics file generally has the same name as the audio file. For example, song.mp3 and song.lrc. The file .lrc is simple like text but it is quite hard to make, this can be done well with several software. You can find more information about how to make LRC file on the internet or in this site http://www.mobile-mir.com/en/HowToLRC.php
