Contrast and Readability:

• Negative TN LCDs can offer higher contrast in certain lighting conditions. The light text against the dark background can make the display easier to read in low-light environments, as the light segments stand out more clearly.
• However, like standard TN displays, the contrast and viewing angles are still limited. When viewed from the side or at an angle, the display may become washed out, and text may become difficult to read.

Power Consumption:

• TN negative displays are still power-efficient and are suitable for devices that require low power consumption. They work in a similar way to positive TN displays, with individual segments being turned on or off to form the characters.
• These displays are often used in battery-powered devices like watches, clocks, and other handheld electronics where low energy consumption is important.

Color and Aesthetics:

• The light text on a dark background can give a sleek, modern look to the display, which is why negative displays are often favored in designs that require a more contemporary or professional appearance.
• Common colors for the light segments include white, blue, and green, although variations may exist depending on the manufacturer.
