Join Zahraa Khalil for an in-depth discussion in this video Introduction to the liquid crystal display (LCD), part of Learning Arduino: Interfacing with Hardware.
- [Instructor] LCD stands for liquid-crystal display.…LCD is one of the components that can be used…with Arduino board to show text or graphics.…The principle behind LCD is to energize…a series of crystals to appear either opaque…or transparent against a lighted background.…The two major types are alphanumeric LCD…and graphical LCD.…The most common alphanumeric LCD device…is 16 by two LCD.…
It can display two lines of 16 characters.…A 16 by two LCD simply means having two rows…and 16 columns,…so basically two lines to show the text.…And the same thing applies if you have any other type.…Eight by two.…Five by two.…The first one is reserved for columns…and the second one is for rows.…The second common type is graphical LCD.…The graphical LCD device use a single larger grid…of individual lights to display information,…instead of a separate grid for each character.…
The most common graphical layout…is 128 by 64 LCD.…The benefit of using that layout…is that you can display any character…at any resolution you prefer,…and you're not only limited to the five by eight resolution…
