To Build a Novel HDR/WCG Display Model

Recently the High Dynamic Range (HDR) display has been a focused topic in display area, especially with the development of Organic Light Emitting Diode (OLED) technique and Quantum Dot Liquid Crystal Display (QD-LCD) technique, it has been possible to achieve a higher luminance and lower black level in commercial product application. However, currently the OLED display or QD-LCD display could attain a peak luminance for around 500–800 cd/m2, which is better than traditional Liquid Crystal Display (LCD) but far away from BT.2020 standard expectation. To reach a higher luminance, Helge Seetzen et al. had built a novel LCD-DLP display model, using a Digital Light Projector to replace the conventional LCD’s backlight, and using the LCD panel as color controller, which could display impressive high dynamic range images. But the disadvantages were that the system was complex, and the color gamut was smaller than common commercial displays. So in this study, an LCD-DLP display prototype was firstly built and optimized, then the display was calibrated and measured. Finally we proposed to use the color filter to enlarge the color gamut.
