Abstract
The NIST ambient contrast ratio measurement method was used in this experiment to measure the ambient CR of different display in market.The samples include: transmissive LCD,transflective LCD,e-Ink,color e-Ink and Interferometric modulation mirasol display.Their sunlight readability were also compared under sunlight by human eyes.The ambient CR of these displays were qualitatively and quantitatively analyzed.Some methods to enhance sunlight readability were found: For LCD,enhancing LCD panel brightness will enhance LCD sunlight readability.for transflective LCD and reflective display,enhancing the reflectivity of display area will enhance their sunlight readability.
