Small OLED Display Module,0.71-inch Smallest OLED Screen

Small OLED Display Module 0.71-inch COG Type

Model No. REX004864A

The REX004864A is one of our smallest OLED solutions—a 0.71-inch 48x64 COG (Chip-on-Glass) Passive Matrix OLED display module. With module dimensions of just 13.90 × 22.0 × 1.26 mm and an active area of 10.54 × 14.70 mm, this small OLED display is an ideal fit for small display applications such as wearable devices, handheld instruments, and compact control units.

This small OLED display module integrates the SSD1306 driver IC, supports I2C interface, and offers flexible FPC options to meet a variety of hardware integration needs. Available FPC types include ZIF and Hotbar, allowing easy adaptation to different connection methods.

Engineered for stable operation in harsh environments, the REX004864A supports a wide temperature range from -40°C to +80°C. With a typical current consumption of just 15 mA, this small OLED screen is perfectly suited for power-sensitive, battery-operated systems.

Overview of the REX004864A Small OLED Display

Technical Specifications of the REX004864A OLED Display Module

No.	Symbol	Function
1	C2N	Positive Terminal of the Flying Inverting Capacitorr Negative Terminal of the Flying Boost Capacitor The charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.
2	C2P
3	C1P
4	C1N
5	VBAT	Power Supply for DC/DC Converter Circuit This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used.
6	NC	No connection.
7	VSS	Ground of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground.
8	VDD	Power Supply for Logic This is a voltage supply pin. It must be connected to external source.
9	RES#	Power Reset for Controller and Driver This pin is reset signal input. When the pin is low, initialization of the chip is executed.
10	SCL	Host Data Input/Output Bus When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. When I2C mode is selected, D2 & D1 should be tired together and serve as SDAout & SDAin in application and D0 is the serial clock input SCL.
11	SDA
12	IREF	This is segment output current reference pin. When external IREF is used, a resistor should be connected between this pin and Vss to maintain the IREF current at a maximum of 30uA. When internal IREF is used, this pin should be kept NC
13	VCOMH	Voltage Output High Level for COM Signal This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS.
14	VCC	Power Supply for OEL Panel This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used.
