Displaying information is one of the crucial steps in electronic projects. So using LCDs has always been one of the most popular ways to display information. 16*2 LCD module is yellow with an orange backlight display module. These are brand new and high-quality displays with orange backlight. It ensures high contrast and a wide viewing angle. This display is larger than a normal LCD display. These are big character LCD display modules with black text on the Orange background. LCD modules are the most prominent as they are low cost and program friendly, hence these modules are commonly used in the embedded system.
16*2 LCD module consists of 16 columns and 2 rows, so it has 32 (16*2) characters in total. Each character has 40pixels (5*8) and thus for 32 characters there 1280 pixels (32*40). LCD modules are the most prominent as they are low cost and program friendly, hence these modules are commonly used in the embedded system. An interface IC HD44780 is attached to the backside of the LCD module to determine the position of the pixel. This IC gets commands and data from the microcontroller and processes it, thus display it on the screen. Using a resistor or PWM the color can be dimmed easily.
It is quite simple to work with these LCDs s and they have full compatibility with all microcontrollers and processor boards. This display module works on 5V and has a white backlight which can be on or off as per requirement. This module consists of a minimum of 6 I/O pins to interface this LCD screen. Moreover, it can work in both 4 bit and 8-bit MCU interfaces.
