Product Description
The QIHAN 2.7 Inch OLED Display Module is a high-performance graphic display solution designed for industrial control systems, medical devices, smart electronics, and embedded applications. Featuring a 128×64 resolution with Passive Matrix OLED technology, this module provides excellent contrast, fast response time, wide viewing angles, and superior image quality.
Unlike traditional LCD technology that requires a backlight, OLED pixels generate their own light, providing deeper black levels and enhanced readability under various lighting environments while consuming less power. The module supports both 4-wire SPI and 8-bit parallel communication interfaces, allowing flexible integration with multiple development platforms and controllers.
QIHAN also provides OEM/ODM customization services, including display colors, power supply options, module dimensions, viewing direction, graphics, and touch functionality to satisfy various project requirements.
