Raystar’s Transflective TFT LCD Modules: Optimized for Sunlight Readability

Raystar’s Transflective TFT LCD Modules: Optimized for Sunlight Readability

In industrial and outdoor environments, display visibility under direct sunlight is a critical requirement. Raystar Optronics addresses this challenge with its innovative transflective TFT LCD modules, designed to deliver exceptional readability in both bright and dim lighting conditions. The transflective modules from Raystar help to enhance system life and increase energy savings due to the lower power requirements and reduced heat generation. Currently, Raystar offers two new transflective TFT modules for immediate evaluation and quotation RFN02000A2A07WDNN00 (2.0-inch, 240×320 resolution, IPS) and RFN05000A2A08WDNN00 (5.0-inch, 800×480 resolution, IPS).

Key features: Excellent sunlight readability: Transflective layers reflect ambient light, improving visibility with high contrast in direct sunlight Power efficiency: Reduced backlight reliance lowers power consumption and extends battery lifespan in portable devices Flexible integration: Multiple sizes and resolutions available with various interface options for support of diverse design needs Wide Temperature Range: Reliable performance in harsh environments Optimized design: for portable, industrial and outdoor devices

What Is Transflective Technology?

Transflective TFT displays combine the benefits of transmissive and reflective technologies. In low-light or indoor settings, the backlight ensures clear visibility. Under sunlight, the display reflects ambient light, enhancing contrast and readability without relying solely on the backlight. This dual-mode operation makes transflective displays ideal for energy-efficient and sunlight-readable applications.
