2004a lcd module datasheet factory

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!

Winstar WH2004A is a Character LCD 20x4 display which is built in with ST7066 controller IC; its default interface is 6800 4/8-bit parallel. These 20x4 LCD modules are also available in SPI and I2C interface by using RW1063 controller IC. WH2004A is available in several different backlight colors including blue, green, white, yellow-green, amber, red, white, and RGB LEDs. There are different character fonts/texts available for ST7066 IC including English/Japanese, English/West European, English/Scandinavian European, or English/Cyrillic (Russian) as options.

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.

ERM2004DNS-1 is 20 characters wide,4 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with white color included can be dimmed easily with a resistor or PWM,ffstn lcd negative,white text on the balck color,wide operating temperature range,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set. It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

I2C/TWI LCD2004 module compatible with Gadgeteer is a cool lcd display with a high speed I2C serial bus from DFRobot. With the limited pin resources, your project may be out of resources using normal LCD shield. The LCD display is a 4x20 character STN white display with a blue LED backlight.

With this I2C interface LCD module, you only need 2 lines (I2C) to display the information.If you already have I2C devices in your project, this LCD module actually cost no more resources at all. Fantastic for Arduino based project.
