Description

WEA160128B series has a resolution of 160x128 dots, with a diagonal size of 1.92 inches, and is built-in with the CH1120 OLED IC. It supports a 4-wire SPI interface, providing excellent high-color contrast (contrast ratio: 10,000:1), sharpness, and image consistency.

The WEA160128B series of COG graphical OLED modules additionally feature a PCB board, providing four screw holes for customers to securely mount the module onto their application products. In addition, the WEA160128B model is an extension of the WEO160128B model. Customers who do not need a PCB board can choose the WEO160128B model as your best solution.

This 1.92-inch COG OLED series module can be applied in control panels for medical, smart home, smart building equipment (including residential and office), lighting management, heaters, smartwatches, sports watches, and other devices.

The logic power supply voltage for this COG OLED is 3V to 3.3V, with a driving method of 1/128 duty, supports 16 (4-bits) grayscale ,consuming a current of 160 mA (typical value) with a 50% display screen. The module's operating temperature ranges from -40℃ to +80℃, and its storage temperature ranges from -40℃ to +85℃.

Interface Pin Function

No. Symbol Function
1 GND Ground for logic and analog. This pad should be connected to GND externally.
2 VDD Power supply for logic and input/output
3 SCL serial clock input
4 SI serial data input
5 RES This is a reset signal input pad. When RES is set to “L”, the settings are initialized. The reset operation is performed by the RES signal level. This pin internal pull high.
6 A0 This is the Data/Command control pad that determines whether the data bits are data or a command.
A0 = “H”: the inputs at D0 and D1 are treated as display data.
A0 = “L”: the inputs at D0 and D1 are transferred to the command registers.
7 CS This pad is the chip select input. When CS = “L”, then the chip select becomes active, and data/command I/O is enabled.
