A simplified scenario is given to illustrate the basic steps a designer takes in selecting a flat-panel display. The attributes of flat-panel displays are then examined and compared to those of cathode-ray-tube (CRT) displays. Criteria for using one or the other are given. Cost factors are considered 相似文献

LCDs versus CRTs-color-calibration and gamut considerations 总被引:1,自引:0,他引:1
Sharma G. 《Proceedings of the IEEE. Institute of Electrical and Electronics Engineers》2002,90(4):605-622
This paper presents a comparative evaluation of liquid-crystal displays (LCDs) and cathode-ray tube (CRT) displays from a color-rendition and color-calibration perspective. Common display calibration models and assumptions are reviewed and their applicability to LCDs and CRTs is evaluated through an experimental study. The displays are compared with respect to the color-calibration accuracy, ease of calibration, and achievable color gamut. The offset, matrix, and tone-response correction model commonly employed for CRT color calibration is also suitable for color calibration of LCDs for most applications, though the calibration error for LCDs is higher For the prototype LCDs used in the experimental study, large color variations significantly above the calibration accuracy are observed with changes in viewing angle. Under typical viewing conditions, LCDs provide a significantly larger color gamut than CRTs primarily due to their higher luminances 相似文献

FED up with fat tubes 总被引:2,自引:0,他引:2
Field emission displays (FED) offer the best and brightest of two display worlds: the bright picture of bulky cathode-ray tube devices and the trim flat-panel picture of liquid-crystal displays. The similarities and differences between FED and CRT are briefly mentioned. The principles of FED operation, and the fabrication of the emitter array and anode, are described 相似文献

为了定量评价两种技术在视觉研究实验中的适用性,本文根据文献分析和视觉研究需求设计了显示器性能测试系统与测试流程,对一台阴极射线管(CRT)显示器和两台通用液晶显示器作为视觉刺激显示设备的关键性能进行测试。结合心理物理学理论,特别是韦伯定律,详细地分析和比较了各项测试结果。实验结果显示所有的显示器有不同的Gamma特性,需要进行相应的Gamma校正之后才能线性呈现图像的灰度级;CRT显示器在响应时间上具有绝对优势,但屏幕空间均匀性和独立性较差;相比于CRT显示器,LCD显示器具有较高的亮度和较好的空间均匀性和独立性,但是响应时间偏慢,而且相邻两帧图像之间独立性较差。这些测试结果表明,CRT显示器仍然是高动态特性视觉刺激显示的首选,而LCD显示器可以用于呈现对空间亮度一致性和空间的独立性要求高,但对响应速度要求不高的视觉刺激。 相似文献

Tomorrow's TV - the grating light valve 总被引:1,自引:0,他引:1
《Spectrum, IEEE》2004,41(4):38-41
The host of technologies tussling to displace the CRT have yet to face one strong contender: the grating light valve (GLV). This paper describes the construction and operation of GLVs which are MEMS technology electrostatically operated ribbon-shaped mirrors. Their main application, also outlined in this paper, is in large sized, high quality laser projection displays. 相似文献
