Graphic Small OLED Display Module, Small OLED Screen 48x64, 0.71"

Model No. REX004864A

REX004864A is the smallest OLED display module in our product line; the diagonal size is only 0.71inches. This small OLED has resolution of 48 × 64 pixels, using SSD1306 controller IC. The OLED display can be emitting light by itself, there’s no need for backlight. Therefore, REX004864A is thinner than other TFT LCD modules of the same size. This small COG OLED screen display supports I2C interface, and its operating temperature ranges from -40 to+80°C. REX004864A offers different types of FPC such as ZIF and Hotbar FPC.

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.
