2004a lcd module datasheet manufacturer

RC2004A is 20 characters x 4 lines monochrome LCD display module. The RC2004A LCD display has the same specs as RC2004A1. The only difference between them is the position of pins. RC2004A has 16pins on the PCB; pins of RC2004A1 are on the FFC connector. Default interface of RC2004A LCD display is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they’re available as well, but the IC will be replaced with RW1063. Power supply of LCD display RC2004A is 5V (3V is optional). Negative voltage version is available for 3V power supply.

Raystar provides various LED backlight combinations for RC2004A display LCD, such as white, yellow-green, amber, red and RGB. You can choose module with LED backlight or without it. There are many LCD modes to choose from, including STN negative, blue ; STN positive, gray/yellow-green ; FSTN positive, white ; FSTN negative, black. RC2004A display LCD 20x4 offers a selection of fonts, for instance, English/Japanese, Europe and Cyrillic (Russian), etc. If you’d like to obtain full datasheet of LCD 20x4, please contact us for more info!

LCD modules are very commonly used in most embedded projects, the reason being its cheap price, availability, and programmer-friendly. Most of us would have come across these displays in our day to day life, either at PCO’s or calculators. Alphanumeric Graphical LCD (2004A) is a 20x4 Blue Coloured Liquid Crystal Display. It can display 4 lines of text and each line can have up to 20 characters in it, which is bigger than the 16x2 LCD displaybut the programming is almost same. These characters can either be text, numbers, graphical symbols or even custom characters. It can be used in DIY projects, to display the data on IoT projects, etc.

We know that each character has 40 Pixels and for 80 Characters we will have 3200 Pixels. Further, the LCD should also be instructed about the Position of the Pixels. It is a hectic task for the microcontroller, hence Driver IC like ST7066 is used, which is mounted on the backside of the LCD Module.it takes data from the Microcontroller and processes them to display on the LCD Screen. You can use it in 8 bit parallel interface or 4 bit parallel interface mode if you need to connect fewer lines to the microcontroller.

There are not many differences between the two LCD screens apart from the obvious one that 16*2 can display only 32 characters and 20*4 can display 80 characters. So you have to choose the display according to your needs. If you need a display to show a lot of data then go for 20*4 size and if there is not too much of data to display then go for 16*2 LCD. It also depends on the packaging size of your project. If space is at a premium then go for smaller sized 16*2 else its 20*4.

4 line, 20 positions alphanumeric Standard LCD 20×4 with HD44780 (or compatible) display controller and the standard 4/8 bit parallel interface. The optional available I2C interface fits right on the back of the display and turns its interface from parallel to simple 2-wire I2C (perfect for microcontrollers like Arduino to save on I/O ports).

Standard LCD 20×4 (2004A) green LCD character display with bright yellow LED backlight, high contrast, and optional serial interface (I2C, SDA/SCL) for microcontrollers. The display needs a 5V power supply for operation. With the I2C interface installed on the backside of the Standard LCD 20×4, the backlight can be controlled by software as well. Many different libraries for different programming languages and controller families are available, also countless examples.

Character display module is an LCD module with a certain number of rows and columns, and has a green or blue backlight and white character. These displays can usually be used to display text, characters and numbers. The contrast can be adjusted by connecting a potentiometer to pin 3. Pin 15 and 16 are for backlight. You can use 6 pins E, RS, DB4, DB5, DB6, DB7 to interface the display with Arduino.
