Abstract

A higher color gamut can bring more comfort to one’s watching experience; therefore, it is a key aspect when assessing the quality of the display. To improve the color gamut of a display, many techniques have been used. Although some techniques have been claimed to work, the overall quality of the color gamut of the display still does not satisfy many researchers. In this paper, we will consider several key factors that can affect the color gamut of the newly developed laser display system, including the center wavelength of the Quantum dot film, the efficiency of the Brightness Enhancement Film, and the quality of the color filter of the liquid crystal display panel. An improvement of nearly 45% can be achieved through fine tuning of the key factors when compared with our earlier models without finetuned ones. The average color gamut of the laser quantum dot backlight display system can reach up to 110% NTSC color gamut that yields vivid color results.
