컬러유니버설 측면에서의 LCD TV와 OLED TV의 색채재현 비교 연구

Abstract

Changes in the Earth's environment, human lifestyle changes, such as the rapid development of digital devices is happening. So, there are human visual variously changed. Therefore, the interest in a Color-Universal is required. Color-Universal is to consider a wide range of color vision, including people with partial color blindness and the elderly. Especially for large-sized TV trend is continuing, due to the development of the display industry. Therefore, modern people are constantly exposed to the light stimulus, by looking more and more clear digital image. People with a variety of color vision is required, the display can more easily distinguish the colors. So it is necessary to compare and check to see the types of display. Therefore, the present study was to compare the color reproduction of the state of OLED TV and an LCD TV. In terms of Color-Universal, which TV is better color reproduction evaluate the good. To this end, targeted at partial color blindness and the elderly, an LCD TV and OLED TV was tested compared. Through experiments, the OLED TV was evaluated to be favorable in terms of Color-Universal. OLED TV is the color vision condition was rated better than LCD TV, characteristics of OLED TV is as follows: First, the wide color gamut of the OLED TV. As widen the gamut, color representation of high saturation is possible. Therefore, OLED TV was easy to distinguish between colors, so a variety of colors can be implemented. Second, the fine brightness gradations. OLED TV is capable of expressing delicate lightness and a complete black representation. So could better discriminate the colors of similar brightness compared to LCD TV. Third, the excellence of Color Reproduction Range. If the OLED TV is maintained with high color reproduction, regardless of the gray level. Therefore, various saturation level expression was achieved. However, the Color Reproduction Range of the LCD TV was decreased in the low gradation.
