Clear Visibility Even Under Direct Sunlight
Outdoor environments and high-brightness conditions often make standard TFT displays difficult to read. Eileentek’s Sunlight Readable Display technology enhances display brightness, improves contrast, and delivers stable, reliable visual performance for industrial and outdoor applications.
Displays hard to read in bright sunlight
Most standard TFT display and monitors are rated between 200 and 300 (cd/m2). If it installed indoors, these displays are usually of sufficient brightness to be easily read. But for use in outdoor environment or even direct sunlight, you will find that content on TFT displays with normal brightness is often difficult to read. Reflection is the major reason. It is difficult to read your screen in bright sunlight, as the strong light reflecting off the screen's surface washes out the display.
Mostly range for displays:
The most common brightness for indoor displays: 200~300(cd/m2)
The ideal brightness of LED backlight for outdoor displays: 500 to 1500(cd/m2)
What is Sunlight Readable display technology?
There are many technologies to increase the outdoor viewing ability of an LCD display such as high brightness backlight, transflective LCD, optical bonding and surface treatment. However, each has benefits and drawbacks depending on the specific application.
Mostly Technical Solutions:
High Brightness TFT LCD
Transflective TFT LCD
Optical Bonding Technology
Surface Treatment
┃High Brightness TFT LCD
Increasing display brightness is one of the most common ways to improve outdoor visibility. High-brightness TFT LCD modules utilize efficient LED backlight designs to deliver brightness levels of 800–1000 cd/m² or higher.
This solution significantly enhances readability under sunlight without changing the display size. However, it may also increase power consumption and reduce battery life.
Features:
Brightness up to 1000 cd/m² or higher
Enhanced outdoor visibility
Suitable for industrial and outdoor equipment
┃Transflective TFT LCD
Transflective TFT LCD combines the characteristics of transmissive and reflective display technologies, utilizing ambient light to enhance visibility under sunlight while still providing clear images with backlight support in low-light environments.
This technology offers both low power consumption and excellent readability across various lighting conditions, making it ideal for portable and outdoor devices.
Features:
Excellent sunlight readability
Lower power consumption
Ideal for portable devices
Supports various lighting environments
┃Optical Bonding Technology
Optical Bonding technology eliminates the air gap between the LCD and protective glass, reducing light reflection while enhancing display performance and touch accuracy.
Features:
Reduce light reflection
Enhance contrast ratio
Improve touch sensitivity
Increase structural durability
Prevent dust and moisture ingress
Reduce fogging issues
┃Surface Treatment
Anti-Glare (AG) and Anti-Reflection (AR) coatings effectively reduce reflections from external light sources on the display surface, improving outdoor readability.
AG (Anti-Glare) Treatment
AG surface treatment creates a matte finish that minimizes light reflection and glare interference.
AR (Anti-Reflection) Coating
AR coating reduces surface reflections, enhancing display clarity and contrast performance.
