Sunlight
Readable LCD panels typically produce a maximum brightness
(white llight) of 200-350 nits, which is insufficient luminance
(brightness) in environments where they are exposed to high ambient
lighting or direct sunlight. It is VarTech Systems' experience that
a luminance greater that 100
footLamberts (343 nits) is required for daylight applications, and
a luminance greater than 200 footLamberts (686 nits) is required
for sunlight readable applications. It should be noted that the
contrast ratio of the panel and the reflectance of the viewing surface
also play significant roles in determining a display's luminance
requirement in high ambient lighting conditiions.
VarTech
offers a comprehensive range of special Sunlight Readable LCD Monitors.
These TFT LCD Monitors are designed to operated in high ambient
light conditions. At 700 nits to 1850 nits of brightness, VarTech's
Sunlight Readable Monitors outperform commercially available products
that washout in direct and/or indirect sunlight conditions. These
superior quality High Bright Sunlight Readable LCD Monitors are
an ideal solution for factory automation, marine/mobile and process
control applications.
