The most common solutions which will enable you to clearly see the image on a bright sunny day are
Sunlight Readable and Optically Bonded .
Sunlight Readable screens employ more (or more powerful) backlights to increase the monitor's brightness to 1,000 nits or more. This added brightness is enough to "over-power" the ambient light and produce viewable images. However, the drawbacks of Sunlight Readable are that they have greater power consumption, produce excess heat, and are more costly than standard LCD monitors.
Another approach is to use optical bonding is the process of injecting a clear, optical-grade resin into the gap between the LCD panel and the protective outer glass, bonding them together. This fills the air gap between the two, eliminating two reflective surfaces. An Anti-Reflective coating is then applied to the outside of the protective glass, minimizing surface reflections.
The net result of the optical bonding process is a drastic (up to 98%) reduction in reflections, and a significant increase in contrast ratio. This produces a tremendous improvement in viewability in direct, bright sunlight.
In addition to the obvious improvement in image quality outdoors, Optical Bonding also provides several other important benefits:
Optically Bonded LCD monitors are ideal for use in a wide range of industries and applications:
In summary, Optically Bonded monitors provide excellent image quality even in bright sunlight. They are more rugged and durable, and cost less than Sunlight Readable monitors.
