FAQ of Character LCD Display

What is the difference between 20x4 and 16x2 character LCD display modules?

The core difference lies in display capacity and application scenarios. The 16x2 LCD only supports 16 characters per line with 2 lines, while the 20X4 LCD DISPLAY supports 20 characters per line and 4 lines, with larger display area and more data display volume. It can show more parameter data, prompt information and working status at one time without page turning. In terms of performance, both adopt mature monochrome STN technology with consistent stability, but the 20x4 module is more suitable for industrial equipment requiring multi-data simultaneous display, while 16x2 is more for simple consumer electronic products.

Can the 20x4 LCD DISPLAY work stably in high and low temperature industrial environments?

Yes. Our industrial-grade 20x4 monochrome LCD module is specially optimized for harsh working environments, with a working temperature range of -20℃ to +70℃ and storage temperature of -30℃ to +80℃.
