0.31″ 32×62 Monochrome OLED Display – LGO3262A-031

The Longtech LGO3262A-031 is a compact 0.31-inch 32×62 monochrome OLED display designed for wearable electronics, miniature instruments and space-constrained embedded systems. The OLED panel measures only 6.2 × 11.88 × 1.0 mm, with a 3.82 × 6.986 mm active area. It uses 0.10 × 0.093 mm pixels with a 0.12 × 0.113 mm pixel pitch, providing a high-density white-on-black display for icons, status information and compact graphical interfaces.

The module uses an ST7312 OLED driver and supports an I²C serial interface through SCL and SDA signals. The logic supply supports 1.65 V to 3.3 V, with 2.8 V as the typical value. The design also supports an internal DC/DC charge-pump configuration, with a VBAT supply range of 3.5 V to 4.2 V when the internal converter is enabled.

The standard version provides a white monochrome passive-matrix OLED display with 1/32 duty driving. The model-specific drawing specifies an operating temperature range of -20°C to +70°C and a storage temperature range of -30°C to +80°C. Brightness, power configuration and other electrical parameters can be selected according to the final application requirements.
