WEO12832L#D89-FC

PMOLED 0.91'' Graphic 128x32, Yellow color, COG, 3V, Interface SPI (FPC per Soldering), Thinner version + DST (spongy tape), Glare

DESCRIPTION

The 0.91 inch is one of the most popular sizes of COG OLED for wearable displays which received 2017 Taiwan Excellence Award. Winstar Graphic COG 128x32 OLED is also built-in SSD1306 driver IC; it communicates via 4-wire serial SPI interface only. This controller's built-in voltage generation only need a single 3V power supply is needed. Operating temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃. These COG 0.91 inch OLED modules are ultra thin + DST (spongy tape) lightweight and low power consumption which is great for handheld instruments, meters, smart grid, wearable device, E-cigarette, MP3, IoT, etc. One of the significant advantages of COG structure is the FPC usually is bendable comparing to TAB OLED since the FPC is flexible and there is no chip on the FPC. Therefore, the customers have less limitation to design the displays on their applications.

Interface Pin Function

No.	Symbol	Function
1	C2P	Positive Terminal of the Flying Inverting CapacitorNegative Terminal of the Flying Boost CapacitorThe charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.
2	C2N
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	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.
7	VDD	Power Supply for Logic This is a voltage supply pin. It must be connected to external source.
8	CS#	Chip Select This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.
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	D/C#	Data/Command Control This pin is Data/Command control pin.. When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection.
11	SCLK	When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK.
12	SDIN
13	IREF	Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 12.5μA.
14	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.
15	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.
