IF you REALLY WANT TO SOLVE THIS PROBLEM do what casio did for sports fans
attending American footbll and baseball games -- they use a transparent back
panel which can be propped up and viewed with a translucent white panel that
is illuminated by sunlight behind the TFT matrix - it works in a pocket TV --
it hould work fine with any of the Thinkpad projection TV systems -- the TP
with the detachable LCD screen -- or one of the overhead projector screens.
This solves the main problems with reflected sunlight illumination and low
power backlight vs TFT screens.
> Nevertheless, why not a secondary backlight? Could be turned on
>in bright conditions for maximum readibility in sunlight, off for max
>battery life (or just a brighter main backlight for everything--turn it up
>in the sun, down indoors). ThinkPads are generally considered to have
>screens that are not as bright as their competition's.
