Product Introduction

CH091L002A 128X32 0.91 Inch Monochrome OLED Display: Compact Graphic Excellence

The CH091L002A, a 0.91-inch monochrome OLED display from Chenghao Optoelectronic, is engineered for compact graphical applications requiring high precision and efficiency. With a 128×32 resolution, it delivers crisp white graphics, making it ideal for wearables, small IoT devices, and portable instruments where space is at a premium.

Its ultra-compact dimensions (30×11.5×1.2mm) and lightweight design (1.05g ±10%) enable seamless integration into slim products. The 22.384×5.584mm window area, paired with 0.175×0.175mm pixel pitch and 0.159×0.159mm pixel size, ensures sharp text and icons.

The 0.91 inch Oled display operates from a 2.8-3.3V operating voltage to power the SSD**** driver IC, with a 1/32 duty cycle, ensuring both low power consumption and stable performance. A four-wire SPI interface and a 15-pin (1x15) pinout simplify connection to a microcontroller, while chip-on-glass (COG) technology enhances durability.

Whether used in fitness trackers or smart sensors, this display combines compactness, clarity, and efficiency to meet the demands of miniaturized electronic devices.
