产品叙述
0.91寸OLED显示器模块是最常被采用作为穿戴式显示器的PM OLED(被动矩阵式OLED)小尺寸之一。华凌WEO012832D荣获2017台湾精品奖是市场上最受欢迎的COG图形0.91寸 OLED模块;分辨率为128x32 像素，外形尺寸为30×11.5 mm，AA有效区域尺寸为22.384×5.584 mm。此款内置SSD1306 IC，模块控制接口仅能使用串列式4线 SPI。因为是OLED面板无需背光源，此款使用COG工艺，所以显示器模块非常的薄仅1.26 mm，重量轻且低耗电流，超高对比度且视角超过175度，所以非常适合手持式产品、量测仪器、智慧电表、穿戴式产品、电子烟、物联网设备等等。 COG OLED与TAB OLED有个很重要的差异是因为COG模块的IC是打在玻璃上，因此COG OLED 模块的FPC多半是可以饶折的，因而在客户端的产品设计上较为方便。此型号OLED模块可支持内部升压及外部供电。

Pin功能定义
| No. | 符号 | 功能说明 |
|---|---|---|
| 1 | C2P | Positive Terminal of the Flying Inverting Capacitor Negative 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. |
| 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 30uA. |
| 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. |
