Understanding the Key Parameters of Sunlight-Viewable Outdoor LCD Monitors

In outdoor industrial environments, monitors often face challenges such as direct sunlight, strong light interference, and complex weather conditions. Ordinary LCD monitors often struggle to display content clearly in such environments, hindering information transmission. Therefore, sunlight-viewable outdoor LCD monitors have emerged, ensuring clear and accurate display even under strong light through the optimization of a series of key technical parameters. This article will detail these key parameters and introduce LEEHON Technology’s solutions in this field.

I: Key Parameters of Sunlight-Viewable Outdoor LCD Monitors

1. Brightness
   Brightness is a core parameter for sunlight-viewable monitors, usually measured in nits (cd/m²). Ordinary indoor monitors have a brightness between 200-300 nits, while outdoor monitors need at least 1000 nits to remain clear under direct sunlight. Some high-end outdoor monitors can reach 1500-2000 nits or even higher. For example, outdoor advertising screens and traffic sign screens typically require 1500-2000 nits of brightness to ensure clear display even in midday sunlight.
2. Contrast Ratio
   Contrast ratio is an important indicator of a display’s brightness and darkness. Outdoor displays typically have a contrast ratio of 1500:1 or higher, with high-end products reaching 2000:1. High contrast ratio ensures that images and text remain clear and sharp even in strong light, without blurring or graying.
3. Resolution
   Outdoor displays typically have a resolution of 1280×720 pixels (HD), with some high-end products reaching 1920×1080 pixels (FHD). Higher resolution ensures image detail, making text and image details clearly discernible even on small screens.
4. Viewing Angle
   Outdoor displays typically use IPS or VA panels, supporting a wide viewing angle of 178°. This design ensures consistent image information when viewed from multiple angles, making it suitable for multiple viewers simultaneously.
5. Protection Rating
   Outdoor displays need to be waterproof, dustproof, and corrosion-resistant. The screen surface typically has an IP65 or IP67 protection rating, effectively preventing the intrusion of rain, dust, oil, and corrosive gases, thus extending the device’s lifespan.
6. Wide Temperature Range
   Outdoor displays need to withstand extreme temperature environments, with an operating temperature range typically from -30℃ to 80℃. This wide temperature design ensures stable operation in both extremely cold and hot regions.
7. Automatic Light Sensing Adjustment
   Many outdoor displays are equipped with automatic light sensing adjustment. This function automatically adjusts the screen brightness according to ambient light, ensuring clear visibility in strong light and automatically reducing brightness at night to avoid excessive glare.
8. Optical Lamination and Anti-Reflective Coating
   To further improve visibility, some outdoor displays use optical lamination technology to eliminate the air layer between the touchscreen and the TFT, reducing internal reflections. In addition, an anti-reflective coating can reduce the screen’s reflectivity from 4-5% to below 1.5%.
