A display becomes less viewable
in a bright ambient light. This is true for both light
emitting panels such as an OLED or for a transmissive
LCD display that uses a backlight. In a bright ambient
environment, the light from the sun competes with the
light from the display and the perceived contrast goes
down. We have two soutions to deal with this intrinsic
problem, high brightness solution and transflective
technology solution..
High brightness
Solution Building a stronger backlight
unit behind the display or more efficient to guide
the light from the source to the panel surface, It
make the display viewable under sunlight.
Transflective
Technology Solution The transflective technology
gets enough light from a backlight unit to see the display
in darker environments and under bright ambient conditions,
light coming through the display is reflected. Such
enhance the brightness on the panel surface not only
from the backlight unit but also from the reflection.
