WEP012832N – Graphic OLED display from Winstar

The WEP012832N is a COG graphic OLED module with a PCB board, featuring a resolution of 128×32 dots and a diagonal size of 2.23 inches (active area: 55.016 × 13.096 mm). It includes a built-in SH1106 driver and supports communication via 6800 or 8080 parallel, 4-line SPI, and I2C interfaces. The logic power supply voltage ranges from 2.9V to 3.5V, with a typical value of 3.3V. It operates with a 1/32 duty cycle and features internal power boost and external power supply capabilities. The series is equipped with a metal frame and four screw holes, facilitating easy module installation, and offers a contrast ratio (typical value) of 10,000:1.

The WEP012832N series eliminates fixed pin headers, enabling semi-custom part numbers with varying pin lengths tailored to specific customer needs. The PCB design retains space for integrating capacitive touch panel modules without requiring redevelopment, ensuring flexibility to meet diverse customer demands seamlessly.

Ideal for applications such as voice recorders, blood glucose meters, MP3 players, mini radio, and medical instruments, the WEP012832N operates reliably in temperatures ranging from -40℃ to +80℃, with storage temperatures extending from -40℃ to +85℃.

Full observation angles

Using an IPS/MVA (or a variation thereof) matrix, the display is readable from all angles. There is no grayscale inversion effect that characterizes popular TN matrices. Also, the decrease in contrast when increasing the viewing angle is much lower.

High brightness (wide format)

High brightness of the image (high brightness) is a feature that is extremely useful when the display is in bright sunlight. With this functionality, the content displayed is fully readable by the user. High Brightness displays can be successfully used, for example, in exhibitions, kiosks, on trains and buses, as digital signage, or as part of other outdoor solutions.
