Description

The WEO004864A is one of the smallest OLED displays, featuring a 48x64 dot matrix with a diagonal size of 0.71 inches. With dimensions of 13.90 × 22.0 mm, an active area of 10.54 × 14.70 mm, and an ultra-thin profile of just 1.26 mm in thickness, this display features a narrow bezel design that maximizes the screen area. Powered by the SSD1306 controller IC, it operates with a 3V power supply and supports I2C interface. As a COG-structured PMOLED display, it offers a self-emitting design with no need for a backlight and low power consumption, making it ideal for portable devices.

The WEO004864A supports both internal DC/DC boost and external power supply options, providing flexibility for different application needs. Whether you're powering the display via an external VCC or using the internal boost converter, it ensures reliable performance in various environments.

This display is perfect for wearable devices, MP3 players, voice recorders, health devices, and more. It supports both portrait and landscape modes for flexible integration. Operating temperature range is -40°C to +80°C, with a storage temperature range of -40°C to +85°C.

Interface Pin Function

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.
