Product Description

This 20x4 LCD Display Module with an integrated HD44780 controller enables the display of 4 rows of 20 characters each in white text on a green background The display is controlled by Raspberry Pi etc.
The 20x04 LCD screen has a HD44780 driver chip. The micro-controller communicates with the driver chip to control the screen.
The driver chip has a SPI communication interface.
Every pixel area can be turned ON/OFF by introducing the electricity through an on-board controller chip.
The module is a low-power consumption LCD Module with a built-in controller, its LED back-light enables viewing in dim lighting conditions. The unit uses the HD44780 interface found in most parallel character displays.
To control the screen, one of the two parallel modes can be used, 8-bit or 4-bit mode.
In the 8-bit mode, all 8 data pins (D0 – D7) are used, and in the 4-bit mode, only 4 data pins (D4 – D7) are used.
The VO pin uses analog voltage to set up the screen contrast level. Hardware contrast adjustment can be done by using voltage divider or potentiometer.
Module dimensions | 98 mm x 60 mm x 14 mm |
Resolution | 20 Characters x 4 Lines |
LCD type | STN, Positive, Transflective, Green |
Back-light | Green |
View Angle | 180 degrees |
Modes | Parallel (8-bit and 4-bit) |
Operating Voltage | 3.3V and 5V |
Operating temperature | from -20°C to +70°C |
Storage temperature | from -30°C to +80°C |

- Reviewed in the United Kingdom on 29 September 2021In every project, I always try get an LCD in, this time I can double the size!
Typically, I have used 16x2 LCD displays and find them fairly easy to setup, with either Arduino or Raspberry Pi. Myriad cable setups can be found online to get this hooked up and started, with one diagram being provided with this pack. Yes, this does not have an I2C board soldered to the back which, if you didn't know, makes connecting LCDs far easier- after you only need to connect three cables. Regardless, with a potentiometer this can be setup and fed with some code to display text, 20 characters along, 4 rows down.
It appears this has a green display as apparent even its off position. I much prefer blue but the function remains the same. I think for one LCD this is pricier than expected.

- Reviewed in the United Kingdom on 21 September 2021When you just need to display some simple data, this is an ideal screen. Fit perfectly with the Arduino project I was working on and works really well.
- Reviewed in the United Kingdom on 6 February 2022As supplied this is a parallel bus LCD display; although an I2C interface is available from the same distributor (or anywhere else); this makes it a little more difficult to get running ( lots of jumper cables ), but once up and running the display is bright with good contrast for the text.
Note: the connectors are blank and no header is supplied so a little less useful for hobby projects.
Good quality and an informative and clear downloadable instruction booklet is available.
- Reviewed in the United Kingdom on 13 November 2020Number Of Items: 3Verified PurchaseIt is a standard parallel display, can be used in 8 bit or 4 bit parallel, but not serial and does not have an SPI interface, the description is mis leading.
- Reviewed in the United Kingdom on 24 October 2021As others have stated the issue is that this is a parallel and not a serial device and that is important to know when you are setting it up with your Arduino. For anyone new needing extra support this is a confusing mistake. There is a downloadable guide to connecting it but you also need to know so that you can install the right drivers. It is good value for money but they do need to update the product description.
- Reviewed in the United Kingdom on 5 October 2021So this is an HD44xxx screen, not a serial one. In some ways, that doesn't matter. You can still use it for your arduino etc. In fact, the HD44 libraries are very reliable and well established.
However, what it doesn't do is use four wires (is it 4 for serial? I think so). It works in parallel mode.
That being said, it is a decent and well priced 4x20 lcd screen! I have no issues with it at all.
- Reviewed in the United Kingdom on 7 October 2021I don't like products whose title/description is wrong or misleading. It is not a serial display but a parallel.
It works well and is well made.It is not high priced and does its function of displaying certain simple data is sufficient.
But, it is not as advertised.
- Reviewed in the United Kingdom on 25 October 2021This LCD is quite expensive considering you can get them for a lot cheaper elsewhere. It works well and does the job. It's like any other LCD that you have probably used in your Arduino projects. The libraries for these are well made and compatibility is no issue.
Just note that the listing says serial but this is not a serial LCD.
