Which statement accurately describes a characteristic of LCD TN (Twisted Nematic) technology commonly found in monitors and laptop screens?
TN panels offer fast response times but often have limited viewing angles
TN panels are known for their slower response times, causing motion blur
TN technology is not suitable for mainstream applications due to high production costs
TN panels provide superior color accuracy and wide viewing angles
Correct Incorrect Unanswered
Answer Description
LCD TN (Twisted Nematic) panels are known for their fast response times, making them suitable for applications that require quick refresh rates, such as gaming. However, TN panels typically have limited viewing angles, which means that the display quality and color accuracy can degrade when viewed from off-center angles. This characteristic is an important consideration when choosing displays for specific use cases.

The twisted nematic effect (TN-effect) was a main technology breakthrough that made LCDs practical. Unlike earlier displays, TN-cells did not require a current to flow for operation and used low operating voltages suitable for use with batteries. The introduction of TN-effect displays led to their rapid expansion in the display field, quickly pushing out other common technologies like monolithic LEDs and CRTs for most electronics. By the 1990s, TN-effect LCDs were largely universal in portable electronics, although since then, many applications of LCDs adopted alternatives to the TN-effect such as in-plane switching (IPS) or vertical alignment (VA).
Many monochrome alphanumerical displays without picture information still use TN LCDs.
TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Viewing the display from above whitens colors, and viewing the display from below dims colors.
