1602a LCD Qapass Display is very basic module and is very commonly used in various devices and circuits. 1602a LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5×7 pixel matrix. 1602a LCD is named so because; it has 16 Columns and 2 Rows. the most used one is the 16×2 LCD. So, it will have (16×2=32) 32 characters in total and each character will be made of 5×8 Pixel Dots.
An LCD (Liquid Crystal Display) screen is an electronic display module and has a wide range of applications. 1602a LCD is very basic display module and is very commonly used in various devices and circuits. The 16×2 intelligent alphanumeric dot matrix display is capable of displaying 224 different characters and symbols. This LCD has two registers, namely, Command and Data.
The term LCD stands for liquid crystal display. It is one kind of electronic display module used in an extensive range of applications like various circuits & devices.
Liquid crystal displays (LCD) come in two main types that are of interest to hobby and DIY makers; Character LCD displays and pixel / graphic LCD displays. LCD displays come in many sizes most often named by the number of rows and then the length of the display line. For example a 16×1, 16×2, 20×4 LCD display will have one row of sixteen characters and a 4×20 LCD display will have four rows with twenty characters in each.
