16x2 LCD DISPLAY MODULE LCD Features and Technical Specifications Operating Voltage is 4.7V to 5.3V Current consumption is 1mA without backlight Alphanumeric LCD display module, meaning can display alphabets and numbers Consists of two rows and each row can print 16 characters. Each character is build by a 5×8 pixel box Can work on both 8-bit and 4-bit mode It can also display any custom generated characters Available in Green and Blue Backlight Brief Description on LCD modules 16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but 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. Now, we know that each character has (5×8=40) 40 Pixels and for 32 Characters we will have (32×40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels. Hence it will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780 is used, which is mounted on the backside of the LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen. You can learn how to interface an LCD using the above mentioned links. If you are an advanced programmer and would like to create your own library for interfacing your Microcontroller with this LCD module then you have to understand the HD44780 IC working and commands which can be found its datasheet.
