What is 2x16 LCD display in 2026

February 14, 2026

Best Embedded display of 2x16 LCD 8-bit.

The Embedded display is 2x16 LCD 8-bit mode Display, which is use for to know the value of the input and output. In the LCD display to know the value like calculator, addition, subtraction, Multiplication and Division.

You can go further details about 2X16 LCD 8-bit Display data sheet to know the dimensions of the device.

In the 2x16 LCD display have LED lights internal and external display. In the device have dot matrix black color led. it is designed systematical to use the device in our daily projects like, Microcontroller, Arduino uno etc., it is best choice for hobbyist or students.

In detail about 2x16 LCD 8-bit display have 16 pins, first to end ie.,16th pin.

1st and 2nd pin is GND and VCC

3rd pin is for contrast the display give 10K preset have 3 terminal 1 terminal for VCC another terminal for GND, middle pin is for LCD 2x16 3rd pin use.

4th, 5th and 6th pins for control and program to give access from Microcontroller or Arduino uno. like as RS, RW and EN these three command in Embedded C code. it has mentioned in program as Sbit RS=P3^0; Sbit RW=P3^1; and Sbit EN=P3^2, these three are very important. don't confuse here is have very critical. most important point in the embedded project.

7th to 14th is 8-bit data lines from the 2x16 LCD 8-bit display, it's had dateline from 8052 microcontroller to LCD Display. To carry data from microcontroller to LCD to display text like, "Hello World".

15th and 16th pin is for to glow the back light, then use these 15th pin as VCC and 16th pin as GND.

To know clear, understand the LCD, then we need to write Keil C code embedded.

Sample C code:

#included <Reg52.h>

#define LCD P2

Sbit RS = P3^0;

Sbit RW=P3^1;

Sbit EN=P3^2;

void delay(unsigned int msec) // Time delay funtion

{

int i,j ;

for(i=0;i<msec;i++)

for(j=0;j<1275;j++);

}

void lcd_cmd (unsigned char item) // Function to send command on LCD

{

dataport = item;

rs= 0;

rw=0;

en=1;

delay(1);

en=0;

return;

}

void lcd_data(unsigned char item) // Function to send data on LCD

{

dataport = item;

rs= 1;

rw=0;

en=1;

delay(1);

en=0;

return;

}

void lcd(unsigned char str1[5]) // Function to initialize LCD

{

lcd_cmd(0x38); //2 lines 5x38 matrix,

lcd_cmd(0x0e); //Cursor Blinking

delay(m_sec);

lcd_data_string(str1);

return;

}

It's just sample code looks like this for 2x16 LCD 8-bit Display, the above Embedded Keil C program, it has dump to Flash Isp programmer to dump into the Microcontroller or Arduino UNO.
