A 20×4 Dual Line 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. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on.

A 204 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. This LCD has two registers, namely, Command and Data.

There is no change code for interfacing standard 16×2 or 20×4 LCD.

Features :

• 20 characters wide, 4 rows

• Black text on the yellow background

• The module can easily interface with an MCU

• The module is a low-power consumption character LCD Module with a built-in controller

• Single LED backlight included can be dimmed easily with a resistor or PWM.

• Can be fully controlled with only 6 digital lines! (Any analog/digital pins can be used)
