Detailed explanation of display technology

3.1 Comparison between VFD and LCD Technologies

Vacuum Fluorescent Display (VFD): The VFD technology used in CP02F-02 is a self luminous display device that works similarly to a cathode ray tube, emitting light by electron bombardment of fluorescent powder. VFD has the following outstanding advantages:

High brightness: still clearly visible even in strong ambient light

High contrast: Self luminous characteristics bring excellent contrast performance

Wide viewing angle: a viewing angle close to 180 degrees, suitable for multi angle observation

Quick response: No ghosting, suitable for dynamic data display

Rich colors: usually presented in blue-green or amber, visually comfortable

However, VFDs also have limitations such as relatively high power consumption and inability to display custom characters.

Monochrome LCD: CP02R-04 uses LCD technology to adjust light transmittance by controlling the arrangement of liquid crystal molecules, relying on backlight illumination. Its advantages include:

Low power consumption: suitable for long-term operation and battery powered scenarios

Long lifespan: LED backlight has a lifespan of up to 100000 hours and requires almost no maintenance

Custom Characters: Supports 8 user-defined characters to enhance information expression ability

Software contrast adjustment: adapt to different environmental lighting conditions

3.2 Display Specifications

The character height of both models is 5mm, ensuring good readability at typical operating distances. The 2-line display of CP02F-02 is suitable for displaying key parameters and simple prompts, while the 4-line display of CP02R-04 can present richer information content and reduce page switching frequency.
