显示技术在历经黑白、彩色和数字高清显示时代后,将迎来大色域显示时代。三枪CRT和阴罩结构的应用,使显示产品由黑白显示走向彩色显示,较好地再现客观世界;随着数字技术的发展,高解析度视频图像的压缩、传输以及解码技术的广泛应用于图像领域,视频信号也由模拟信号转变为数字信号,从而解决了高分辨率画面的传输带宽和画面稳定问题。然而,由于显示发光光源的制约,前三代显示技术仅能再现人眼所能识别的色彩空间的30%,致使70%的色彩无法通过显示让人们来感知,颜色的真实再现是下一代显示的关键。
Display technology in the black and white, color and digital high-definition display era, will usher in a large color gamut era. With the application of three shots of CRT and shadow mask structure, the display products are going from black and white to color display, which can better reproduce the objective world. With the development of digital technologies, the compression, transmission and decoding technologies of high-resolution video images are widely used In the field of image, the video signal is also converted from an analog signal to a digital signal, thereby solving the problem of transmission bandwidth and picture stability of a high-resolution picture. However, due to the restriction of the display light source, the first three generation display technologies can only reproduce 30% of the color space recognized by the human eye, so that 70% of the colors can not be perceived by the display and the true color reproduction is displayed by the next generation The essential.
