What kind of device is it, and what are the advantages of using OLED?
We will explain in simple terms.
What is a pulse oximeter?
It is a medical device that measures blood oxygen saturation without taking blood samples, and checks how much oxygen in the lungs is taken into the blood and transported throughout the body.
It is widely used in the daily health management of people with chronic diseases and in medical and nursing cares.
OLED has a wide viewing angle
A variety of displays are currently used in pulse oximeters. Among them, OLED displays are recommended for displaying readings in an easy‑to‑read manner.
The OLED display has the advantage that the values are clearly visible even when the display is viewed from an angle.
For clear display of measured values
If you look at a traditional display, you may see segments that are not lit. This can make it difficult to read the measured value.
On the other hand, with OLED, only the characters to be displayed are illuminated, so the segments that are not lit are not visible, and only the measured values are clearly visible.

"When I look at the readings from an angle, the numbers are blurry and difficult to read. You have to look at them from the front..."
OLED has the advantage that the display is easy to see even when viewed from an angle. Measurements are clearly visible even when not in front.
"It's hard to see the numbers because you can faintly see the lines not to be shown..."
The non‑displayed area is completely black and does not glow. Numbers are clearly readable.
