Product Description
The QIHAN HQ099PMBX-1 is a compact 0.91-inch OLED display module designed for embedded systems requiring ultra-low power consumption, high contrast, and reliable display performance. Featuring a resolution of 128×32 pixels, this OLED module provides sharp text and graphic display quality while maintaining a compact footprint for space-limited applications.
Built with OLED self-emitting technology, the display does not require a backlight, resulting in lower power consumption, deeper blacks, and superior image contrast compared with conventional LCD displays. With an ultra-wide viewing angle greater than 160°, users can view content clearly from almost any direction.
The module supports a 4-wire SPI interface and operates at a wide voltage range compatible with 3.3V power systems. QIHAN also supports customized interfaces and OEM solutions for different project requirements.
Designed for stable long-term operation, this display is suitable for wearable devices, industrial instruments, medical equipment, IoT products, and embedded development platforms.
