1.54″ 128×64 Monochrome OLED Display – LGO12864C-154

The Longtech LGO12864C-154 is a compact 1.54-inch 128×64 monochrome OLED display designed for industrial instruments, control panels and embedded systems. It has a 42.54 × 21.51 mm module size, a 37.04 × 19.51 mm viewing area and a 35.04 × 17.51 mm active area. The display uses 0.249 × 0.249 mm pixels with a 0.274 × 0.274 mm pixel pitch, providing a clear white-on-black graphical display for icons, status information, measurement data and compact user interfaces.

The module uses an SSD1317 OLED controller and supports 4-wire SPI and I²C interfaces for different MCU and embedded system designs. It supports a standard logic supply voltage of 1.65 V to 3.3 V and uses a 13-pin FPC with a 0.50 mm pin pitch for connection to the host PCB. The interface configuration includes IM1, CS, RES, DC, D0 and D1 signals, allowing serial communication according to the selected interface mode.

The standard version provides a white monochrome OLED display with a compact side-exit FPC structure. The specified operating temperature range is -20°C to +70°C, with a storage temperature range of -30°C to +80°C. The FPC is designed for a 13-pin, 0.50 mm pitch, bottom-contact drawer-type connector. FPC length, connection structure and other mechanical or electrical specifications can be customized according to project requirements where applicable.
