What is LCD display 20×4?
A 20×4 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs. A 20×4 LCD means it can display 20 characters per line and there are 4 such lines. In this LCD each character is displayed in 5×7 pixel matrix.
