从2002年至今,CRT、LCD、PDP电视经过几年的激烈竞争,CRT电视逐渐萎缩,以LCD、PDP为代表的平板电视成为我国家电市场的主导产品。其中,LCD凭借上游链厂和生产厂的优势,在我国家电市场上占有80%以上的份额,正在各领域逐步代替CRT显示设备。由于液晶本身不发光,需要通过外来光源实现透射或反射来显示。目前LCD主要以CCFL为背光源,但CCFL的固有缺陷,使LCD电视显示的图像质量在彩色鲜艳度、图像柔和、自然、真实性等方面不如采用RGB自发光的CRT、PDP电视机。为此,具有色域宽、彩色还原性好等一系列优点的LED背光源开始逐步走向舞台。
Since 2002, CRT, LCD, PDP TV after years of fierce competition, CRT TV is shrinking to LCD, PDP as the representative of flat-panel TVs become the leading home appliance market in China. Among them, LCD with the advantages of the upstream chain plant and manufacturing plant in China’s home appliance market, accounting for more than 80% of the share, are gradually replacing CRT display devices in various fields. Due to the liquid crystal itself is not light, need to be transmitted or reflected by external light source to display. At present, LCDs mainly use CCFLs as backlight sources. However, the inherent defects of CCFLs make LCD TVs display images of images with RGB self-luminous CRTs and PDP TVs in vivid colors, soft images, naturalness and authenticity. To this end, with a wide color gamut, color reproduction and a series of advantages LED backlight began to gradually stage.
