How Does The Lcd Display Module Affect The Overall Cost Of A Wide-range Voltage Regulator?

The wide range stabilizer for ac integrates real-time voltage and status display functions, which involves additional investment in hardware design, display driver circuitry, and more complex software logic support.

LCD display hardware itself requires independent driver components and backlight units. The cost of these components in the BOM (Bill of Materials) is significantly higher than that of traditional single-module regulation units. Furthermore, to achieve stable output over a wide input voltage range, designers need to adjust PCB layout, optimize power filtering, and interface mapping to adapt to the data acquisition and output of the LCD display, which also increases resource consumption during the engineering development phase.
