Brightness: LEDs have a brightness range of 800-8,500 nits, which is higher than the brightness of most LCDs. Depending on whether the display will be indoors or outdoors, brightness may or may not be an issue.
Size: LCD displays are only available in the sizes specified by the manufacturer and are not easily customizable. Some manufacturers offer stretch sizes, but the majority of options have a 16x9 aspect ratio.
Viewing Angle: LED displays have a much wider viewing angle than LCD displays. When viewing an LCD display, the image clarity decreases when you move your gaze away from the center point in either direction.
Temperature: Because LEDs are semiconductors, they can operate at a wide range of temperatures. The operating temperature limits of the meter will be determined by other components. Because the chemical action in the LCD slows down at low temperatures (typically 0°C), a heater may be required in these situations. The maximum temperature of an LCD meter may also be more limited than that of an LED meter, depending on the type of LCD.
Life Span: Either type of display will provide years of continuous operation. However, due to an imperfect seal between the glass plates, LCDs can degrade in high humidity. LEDs have a longer lifespan, lasting around 100,000 hours. LCDs, on the other hand, have a lifespan of only 75,000 hours.
