What is a common type of display technology used in patient monitors?

Liquid Crystal Display (LCD) technology is widely used in patient monitors due to its several advantageous properties. LCDs are known for their low power consumption compared to other display technologies, making them suitable for medical equipment that needs to operate efficiently for extended periods. They also provide clear, sharp images that are essential for monitoring vital signs such as heart rate, blood pressure, and other critical parameters.

Moreover, LCDs can be made thinner and lighter than older technologies like Cathode Ray Tubes (CRT), enhancing portability and ease of integration into various medical environments. The readability in bright conditions is also an important factor, as patient monitors are often used in well-lit clinical settings.

In contrast, while Organic Light Emitting Diode (OLED) technology is emerging and has advantages like better contrast and color representation, it is less common in current patient monitoring applications due to cost and longevity concerns. Tungsten lamp displays are not typically used in patient monitors, as they are outdated technology, and CRTs, while historically significant, are now largely replaced by more modern and efficient options like LCDs. Thus, LCDs remain the standard for their efficiency, portability, and clarity, which are crucial in healthcare settings.
