|
Abstract:
针对传统显示系统在动态范围和色域方面的不足, 在现行高动态范围显示技术和色域扩展技术的基础上, 提出了一种使用白色和宝石蓝两种颜色发光二极管作为背光源的液晶显示系统, 并对系统高动态范围和宽色域的效果进行了论证．根据系统结构和功能将系统进行模块划分, 详细地介绍了信号处理模块、数据转发模块以及背光控制模块的结构及实现方案, 描述了模块间的关系及接口连接．测量结果表明, 显示系统的峰值亮度可达1 258 cd/m2, 黑色亮度低于0.02 cd/m2, 色域覆盖率达45.65% ．相较于传统显示器, 显示系统的动态范围得到很大提高, 色域获得了显著扩展．
To overcome the deficiencies in the dynamic range and color gamut of traditional display system，a liquid crystal display system，using white and emerald light-emitting diodes as backlight，was proposed based on the current high dynamic range display technology and color gamut expansion technology. Then，the feasibility of high dynamic range and wide gamut of the system was demonstrated. The display system was divided into multiple modules according to its structure and function，and the structure and implementation of the signal processing module，data forwarding module and backlight control module，as well as the inter-module relationship and interface connection，were described in detail. The measurement results show that the display system has a peak brightness of 1 258 cd/m2，a black brightness of less than 0.02 cd/m2，and a gamut coverage of 45.65% . Compared with traditional display，the dynamic range of the display system has been greatly improved，and the color gamut significantly expanded
