Note 3 : Definition of Contrast ratio The contrast ratio is defined to be the ratio of transmission or reflection of a symbol at its "on" and "off" state. Transmission/Reflectance at "OFF" state Contrast ratio(K) = Transmission/Reflectance at "ON" state Note 4 : Definition of response time At specific operating voltage and temperature, the times measured by observing contrast or transmission ratio.
