WEO012832R – Graphic OLED display from Winstar

The WEO012832R series is a popular 0.91-inch COG graphic OLED module in the market. This module features a resolution of 128×32 dots and integrates the SH1106 IC, supporting an I2C interface. The IC also facilitates internal power boost and external power supply. With outline dimensions of 30.0 × 11.5 mm and an active area of 22.384 × 5.584 mm, the module is very lightweight due to its COG structure, measuring just 1.26 mm in thickness.

The logic power supply voltage ranges from 1.65V to 3.3V, with a typical value of 3.0V, and operates with a duty cycle of 1/32. Additionally, the module features a wide temperature range, reliably operating from -40℃ to +80℃, with a storage temperature range of -40℃ to +85℃.

This module is particularly suitable for various applications requiring compact and lightweight OLED displays. It is ideal for integrating into devices such as voice recorder, charging cables with embedded OLED displays and keychain lights featuring OLED displays, where space and visual clarity are paramount.

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.
