The WO32032A is a 4.24-inch monochrome graphic LCD display module featuring a 320x32 resolution and built with a COG (Chip-on-Glass) structure. This monochrome STN LCD is ideal for displaying icons, messages, and status indicators in compact devices such as control panels, handheld instruments, medical devices, and industrial monitoring systems.
With an active area of 106.865 × 12.85 mm, this module integrates the ST7586S controller and supports both 4-Line SPI and 3-Line SPI serial interfaces, selectable via software or hardware. A single 3.0V power supply drives both the module and its LED backlight, simplifying integration and enhancing energy efficiency.
The built-in booster circuit generates the necessary Vop, minimizing the need for external components and enabling software-adjustable contrast to suit various lighting environments. A two-piece LED backlight structure ensures even illumination and long-term reliability.
This monochrome LCD module is available in two display types:
