스마트폰 디스플레이 색재현 성능향상에 관한 비교연구 : AMOLED 및 TFT-LCD를 중심으로

Abstract

This paper carries out an evaluation of the quality of preferred colors in digital photography reproduced on the display of smart phones. In order to inquire into the display that has established itself as a major media of the reproduction of digital photographs, this study compares the color reproduction ability of two smart phones equipped with the latest display technologies such as AM-OLED and TFT-LCD and evaluates their colors and image quality. The methods of research include: 1) an analysis of the results of preceding research through the process of an objective evaluation of colors; and 2) addition of details of an analysis of the enhanced display of the newest smart phones and suggestion of a few supplement points. It is safe to say that the scale of delivery of various visual arts through smart phones has recently exceeded that through the analogue methods. According to this flow, an objective evaluation of digital colors and a study on standards have become necessary subjects of research, regarding the way in which a picture taken is digitally reproduced on a display. This paper recorded a comparative analysis of the trend of colors reproduced through smart phones in the processes of producing and generating digital images. The displays are calculated from the range of the performance included within display gamut volume from six categories of database that are luminance, white balance, gray scale linearity, RGB channel, color reproduction and contrast.
