会社のニュース Optimizing Readability & Branding: A Guide to Selecting the Right Monochrome Color for Your 2.42-inch OLED

Introduction
In the design of industrial HMIs, portable medical devices, or consumer electronics, the choice of display color is rarely just aesthetic. It directly impacts readability under specific lighting, conveys brand identity, and can influence power perception. A one-size-fits-all “white” display may not be the optimal solution.

The Engineering Question: Which Monochrome is Right for My Application?
Engineers must balance technical specifications with human factors. The SFOS242JY-12864WBYG from Saef Technology Limited addresses this by offering four distinct monochrome options: White, Blue, Yellow, and Green. This allows for precise matching to the application environment.

Technical Comparison: Beyond the Datasheet Numbers
While all variants share the same mechanical footprint (2.42-inch diagonal, 128x64 pixels) and excellent electrical characteristics, their optical profiles differ:

• White: Offers the highest contrast ratio (2000:1, typical) and is the standard for general-purpose applications where familiarity and clarity are paramount.

• Blue/Yellow/Green: These colors provide superior performance in specific scenarios. For example, Yellow (with CIE coordinates x:0.45, y:0.53, typical) offers exceptional visual comfort and reduced eye strain in low-light or nighttime operation, a principle supported by human factors research on long-duration monitoring.

Designing with Purpose: Matching Color to Context

• Medical/Industrial Handhelds: Amber/Yellow is often preferred for its low-glare and night-vision friendly properties.

• Consumer/Status Indicators: Blue or Green can align with corporate branding or create a distinctive, modern look.

• High-Ambient Light: The 150 cd/m² brightness ensures all color options remain readable.

Extending Functionality with Touch
Regardless of the chosen color, this 2.42-inch OLED can be seamlessly combined with a touch panel from Saef Technology Limited. We offer customized touch solutions that complement the display’s optical stack, creating a cohesive and interactive interface.

Conclusion: Specify with Intent
Offering a choice is a mark of a thoughtful component supplier. By selecting the appropriate monochrome color from Saef Technology Limited， you optimize the end-user experience and product differentiation from the display level up.
