This item is a 6 digit 7-segment LCD display module. It features large black LCD digits displayed against a green backlight resulting in a clear and easy to read display. Communication to the module is via a 5V serial interface requiring only 3 digital pins (CS, WR, Data). Additionally, this 6 digit display module also features a 3 state battery charge icon.

For Arduino users we have also written an exclusive library (HCDisplay) which will help you develop your project with the minimum of effort. This library can be downloaded from the support section of our support forum here:

Hobby components notes: Although this module can display numbers up to 6 digits, for fractional numbers only the 3 right most digits are capable of displaying a decimal point.

Program crashes immediately, this may be due to interrupt! Include the line "DISPLAY_INTR(display)" in your program, it will only generate code when needed.

Refresh rate of digits is very slow or processor is slow. This may be wrong interrupt frequency for a interrupt controlled display. There can be two reason for this: Interrupt not correctly initialized, add "display.begin();" in "setup()"

The last digits in a long display or multiple displays is strange or the program crashes sometimes, remember to change "MAX_DIGITS" in LEDDisplayDriver.h when using more than 8 digits.

Since seven segment display module (Monochrome LCD Display Module) only displays fixed images, the industry is basically a fixed product, and each customer uses different segment lcd screen. If your time is not urgent, our company suggests you directly mold making and customization:

3. Seven segment display module customization screen for the whole industry, basic not standard, it is difficult to find the same one your required size and display the same image products, even if can find, also need to spend a lot of time, and even if you"re lucky enough to find, to find is someone else"s products, is likely to be your competitors are using Lcd screen, it is easy to cause infringement and other unnecessary trouble.
