Description

Winstar's OLED WEO006432A is a 0.49-inch micro OLED display module with a resolution of 64x32 dots. The WEO006432A has module dimensions of 14.5×11.6×1.26 mm and an active area size of 11.18×5.58 mm (Diagonal: 0.49"). The micro OLED display is equipped with a built-in SSD1306 IC, supporting the I2C interface. The module operates with a logic voltage of 3V and a duty cycle of 1/32. Additionally, the module supports an internal charge pump supply and external VCC supply. The OLED micro display, also referred to as a micro OLED screen, boasts a high contrast ratio of 10,000:1.

Featuring a COG (Chip-on-Glass) structure OLED display, this micro display module is ultra-thin and eliminates the need for a backlight (self-emitting). It is lightweight and consumes low power, making it ideal for various applications. The module can operate in temperatures ranging from -40℃ to +80℃, with storage temperatures ranging from -40℃ to +85℃. This small-sized 0.49-inch OLED module is well-suited for wearable devices, MP3 players, portable devices, personal care appliances, voice recorder pens, health devices, and more.

Winstar's 0.49" 64x32 OLED WEO006432A is a versatile micro OLED display module offering high performance, a compact design, and suitability for a wide range of applications.

Interface Pin Function

No. Symbol Function
1 C2N C2P/C2N – Pin for charge pump capacitor; Connect to each other with a capacitor.
C1P/C1N – Pin for charge pump capacitor; Connect to each other with a capacitor
2 C2P
3 C1P
4 C1N
5 VBAT 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 or kept float when the converter is not used.
6 NC No connection.
7 VSS This is a ground pin.
8 VDD Power supply pin for core logic operation.
9 RES# This pin is reset signal input. When the pin is low, initialization of the chip is executed.
Keep this pin HIGH (i.e. connect to VDD) during normal operation.
10 SCL The serial clock input
11 SDA The serial data input/output
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 The pin for COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
14 VCC This is the most positive voltage supply pin. When charge pump is enabled, a capacitor should be connected between this pin and VSS.
