1.54″ 128×64 Monochrome OLED Display – LGO12864A-154

The Longtech LGO12864A-154 is a compact 1.54-inch 128×64 monochrome OLED display designed for industrial instruments, control panels and embedded systems. It has a 42.04 × 27.22 mm panel size, a 37.052 × 19.516 mm viewing area and a 35.052 × 17.516 mm active area. The display uses 0.254 × 0.254 mm pixels with a 0.274 × 0.274 mm pixel pitch, providing a clear graphical display for icons, status information, measurement data and compact user interfaces.

The module uses an SSD1309 OLED controller and supports multiple host interfaces, including 8-bit 6800/8080 parallel, 4-wire SPI and I²C, 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 24-pin FPC with a 0.50 mm pin pitch for connection to the host PCB. The interface configuration includes BS1, BS2, CS#, RES#, D/C#, R/W#, E/RD# and D0–D7 signals, providing flexibility for different communication requirements.

The standard version features a monochrome OLED display with a COG structure. The specified operating temperature range is -40°C to +70°C, with a storage temperature range of -40°C to +85°C, making it suitable for industrial applications requiring extended low-temperature performance. Its extended FPC structure provides mounting flexibility, while FPC length, connection configuration and other mechanical or electrical specifications can be customized according to project requirements where applicable.
