摘　　要：常规电视基于CRT低亮度范围显示技术已无法满足新型显示器要求。介绍了杜比和BBC公司的HDR光电转换特性，揭示了两种方案支持亮度高达2000～10000cd／m^2的技术细节。这两种方案基于人眼视觉系统特性，以较少的量化比特支持10^7高动态范围显示，对提高4K超高清图像质量有重大意义。Conventional CRT-hased low-luminance range TV display technology has been unable to meet the requirements of the new display. This article describes Dolby and the BBC HDR photoelectric conversion characteristics to reveal two schemes technical details supporting hrightness up to 2 000-10 000 ed/m^2. Both schemes are based on human visual system, with less quantization bit to support high dynamic range up to 10^7, to improve the 4K uhra high-definition picture quality which has great significance.
