A technician is helping the marketing department choose a new laptop model. The team often huddles around one screen to review color-accurate layouts, so the display must look consistent even when viewed from the side. Which characteristic of an in-plane switching (IPS) LCD panel best meets this requirement when compared with a twisted nematic (TN) panel?
Self-emitting pixels that eliminate the need for a separate backlight.
Highest native contrast ratios due to deeper black levels.
Fastest pixel response times for reduced motion blur during gaming.
Significantly wider viewing angles with more accurate color reproduction.
IPS LCD technology aligns liquid crystals parallel to the screen, keeping light transmission more uniform across a wide range of angles. This produces noticeably wider horizontal and vertical viewing angles and better color accuracy than TN panels, whose perpendicular crystal alignment causes color shifting and contrast loss when viewed off-center. Although IPS response times are usually slower and costs higher, those drawbacks do not affect the requirement in this scenario. TN offers fast response but poor side-angle viewing, VA offers high contrast, and OLED uses self-emitting pixels rather than a backlight.
