Detailed explanation of display technology

3.1 Comparison between LCD and VFD

LCD (Liquid Crystal Display): CP01R-04 and CP05R-04 are equipped with a transmissive monochrome LCD, relying on LED backlight. Its character height is 5mm and supports software contrast adjustment (only CP05R-04). LCD can still be read in strong ambient light and has extremely low power consumption, making it suitable for devices powered by batteries or requiring heat dissipation.

VFD (Vacuum Fluorescent Display): CP01F-02 adopts VFD technology, self luminous, high brightness, and the color is usually blue-green or amber, which is very eye-catching in dark environments. VFD has fast response speed and no viewing angle limitation, but its power consumption is relatively high and its lifespan is limited by the aging of fluorescent materials (although it can still reach tens of thousands of hours).

3.2 User defined Characters

CP01R-04 and CP05R-04 support up to 8 user-defined characters, which can be used to display special symbols or simple graphics, enhancing the flexibility of information expression. Due to the use of VFD, CP01F-02 does not support custom characters, but its standard character set is sufficient to meet most text display needs.
