OLED Display Applications – Examples

Laser Rangefinders

"I want to know the exact distance to the green somehow…"
A laser rangefinder plays a useful role in such a golf scene.
The following are examples of OLED displays used for laser rangefinders.

How many yards to the green?

At the second shot after the tee shot,
which club should I use next?

The most important information in such a case
is "the remaining distance".

A laser rangefinder is an essential item
at a golf course you go to for the first time.

When you look into the viewfinder
of a laser rangefinder,
Liquid Crystal Display(LCD) with monochrome is
mainly used.

However, a transparent OLED display makes it
possible to produce a colored presentation.

Comparison of LCD and OLED

Liquid Crystal Display (LCD)

Texts produced by LCD in the viewfinder
are black.

In a landscape like the photo above,
the displayed information blends into
the background.
It would be difficult
to recognize the accurate distance.

OLED with multiple colors can be clearly seen
unlike monochrome texts.

Tohoku Pioneer's OLED produces multicolor displays without using a RGB color filter because it uses the deposition technology. Furthermore,
by making full use of the technical expertise of
optical design, it is possible to make wiring patterns and non-emitting segments less visible.

It is simple to use and less stressful due to
the clear display provided within the viewfinder.
