到目前为止,CRTs(阴极射线管)做为典型的电子显示技术在市场上一直处于几乎不可动摇的地位。它具有成本低廉,画面质量高的特点。但在刚刚过去的10年里,液晶显示技术领域的开发使得视听产品和显示方法有了某些显著变化。液晶显示比先前的屏幕更大、色彩更丰富、分辨率更高。但生产成本和最终用户价格仍居高不下,这主要是产率低造成的。液晶显示(LCDs)的主要制造商们矢志追求一个目标,就是制造能在居室或办公室的任何地方安放(或者挂在墙上,或者放在桌子上)真正的薄屏幕电视监视器。这意味着多年的研究与开发将要见成效。而与此同时,虽然还不能打开大规模的消费者市场,这些制造商们却通过为商业通信市场生产显示材料而获得利润。本文旨在对液晶显示(LCDs)的历史、不同的液晶显示技术、在过去10年里取得的显著进步如何导致商业通信产品在设计及应用方面的根本转变和这种进步如何为发信机在大屏幕上显示可视信息提供新的机会做一个简要概述。
Until now, CRTs (Cathode Ray Tube) have been on the market almost unshakably as a typical electronic display technology. It has the characteristics of low cost and high picture quality. However, in the past 10 years, the development of liquid crystal display technology has made some significant changes in audio-visual products and display methods. LCD display larger than the previous screen, richer colors, higher resolution. However, production costs and end-user prices remain high, mainly due to low productivity. Major manufacturers of liquid crystal displays (LCDs) are determined to pursue a true thin-screen TV monitor that can be placed anywhere on a home or office (either on the wall or on a table). This means years of research and development will be successful. In the meantime, while not yet opening up large-scale consumer markets, these manufacturers have made profits by producing display materials for the commercial communications market. This article aims to show how the history of liquid crystal displays (LCDs), different liquid crystal display technologies (LCDs), and significant advances made over the past decade have resulted in fundamental shifts in the design and application of commercial communications products and how such advances have been made to the transmitter Displaying visual information on the big screen offers new opportunities to give a brief overview.
