Winstar introduces the new series of 0.91" graphic OLED displays, designed to combine compact dimensions, low power consumption and maximum integration flexibility for embedded systems and portable devices.
Developed for applications where space optimization, readability and ease of implementation are essential, the series is available in two configurations:
     🔸 Ultra-compact Chip-on-Glass (COG) version, ideal for integrations with minimal depth
          requirements.
     🔸 PCB version, designed to simplify assembly and prototyping.

Both versions integrate the CH1120 driver IC and feature a 128×32 resolution, with 4-bit grayscale support (16 grayscale levels) for more advanced graphic management compared to traditional monochrome displays.
The wide 160° viewing angle and operating temperature range from -40°C to +80°C ensure excellent visibility in both consumer and industrial applications.
An ideal solution for wearables, IoT devices, compact instrumentation, portable electronics and industrial applications requiring energy efficiency, reliability and reduced dimensions.
