Abstract

The main purpose of this article is to incorporate the JND (Just Noticeable Difference) into the design of mobile device display, especially LCD display of mobile phone. JND is the difference threshold between stimuli that can be detectable by human sense. Thirty participants were employed for two experimentations in order to find out JND value of sensation for LCD. The critical design variables of LCD and the affective component of user satisfaction were investigated using AHP and regression analysis. Finally, the JND of design variables of LCD and its characteristics were investigated.
