How to display Chinese characters on STN Characters LCD Module?
Jul 28, 2025| Hey there! As a supplier of STN Characters LCD Module, I often get asked about how to display Chinese characters on these modules. It's a pretty common question, especially for those who are working on projects that require multilingual support. So, I thought I'd share some tips and tricks on how to make it happen.
First things first, let's talk about what an STN Characters LCD Module is. If you're not familiar with it, you can check out STN Characters LCD Module. These modules are great for displaying alphanumeric characters, symbols, and even some simple graphics. They're commonly used in a variety of applications, such as calculators, weight scales, and other small electronic devices.
Now, when it comes to displaying Chinese characters on an STN Characters LCD Module, there are a few things you need to consider.
1. Character Encoding
Chinese characters have a large character set, and you need to make sure your LCD module can handle the encoding. The most common encoding for Chinese is GB2312, which covers a wide range of commonly used Chinese characters. However, if you need to display more complex or rare characters, you might want to consider using UTF - 8, which is a more comprehensive encoding that can handle multiple languages, including Chinese.
2. Character Font and Memory
Your STN Characters LCD Module needs to have the appropriate font data for Chinese characters. Some modules come with built - in fonts, but they might not include Chinese characters. In this case, you'll need to load the font data into the module's memory. This can be a bit tricky, as you need to ensure that the font data is in the correct format and that there's enough memory to store it.
3. Communication Protocol
The way your microcontroller or other control device communicates with the LCD module is crucial. Most STN Characters LCD Modules use serial or parallel communication protocols. You need to make sure that your code can send the correct commands and data to the module to display Chinese characters. For example, you might need to send commands to set the cursor position, select the character set, and then send the actual character data.
4. Example: Displaying Chinese on a Weight Scale
Let's take a look at an example of how to display Chinese characters on a weight scale using an STN Characters LCD Module. You can find more information about Weight Scale Of Character LCD Display.
First, you'll need to connect your microcontroller to the LCD module. Make sure you've set up the communication protocol correctly. Then, load the Chinese font data into the module's memory.
Here's a simple code snippet in Python (assuming you're using a microcontroller with Python support) to display a Chinese character:
import serial
# Connect to the LCD module via serial port
ser = serial.Serial('/dev/ttyUSB0', 9600)
# Send commands to set up the LCD
# For example, set cursor position
ser.write(b'\x0C') # Clear display
ser.write(b'\x80') # Set cursor to the beginning
# Send a Chinese character (in GB2312 encoding)
chinese_char = b'\xB9\xFA' # Example Chinese character '国'
ser.write(chinese_char)
ser.close()
This is a very basic example, and in a real - world scenario, you'll need to handle errors, set up proper communication, and manage the font data more effectively.
5. Using an STN Characters LCD Module for a Function Calculator Screen
Another common application is using the module for a function calculator screen. You can learn more about LCD Module for Function Calculator Screen.
When designing a calculator with Chinese character support, you need to consider the layout of the display. You might want to use different areas of the screen for different types of information, such as input numbers, calculation results, and Chinese prompts.


You'll also need to make sure that the calculator's software can handle Chinese input. This could involve creating a virtual keyboard or using a different input method to select Chinese characters.
6. Troubleshooting
If you're having trouble displaying Chinese characters on your STN Characters LCD Module, here are some common issues and solutions:
- No characters are displayed: Check your communication protocol. Make sure that the baud rate, data bits, and stop bits are set correctly. Also, check if the power supply to the module is stable.
- Characters are displayed incorrectly: This could be due to incorrect encoding. Double - check that you're using the right encoding for your Chinese characters. It could also be a problem with the font data, so make sure it's loaded correctly.
- Some characters are missing: If only some characters are not displayed, it might be that the font data doesn't cover all the characters you need. Consider using a more comprehensive font set or encoding.
